Aerobics For Fitness
Getting in shape and staying fit is not always easy but some ways are easier than others such as aerobics when you do it right. Aerobics For Fitness Provides You With Everything You Need to Know to Make Aerobics Work Right And Produce Real Fitness Results.
Aerobic exercise contributes to the energy deficit, improves cardiovascular fitness and lipid profiles, and also enhances the preservation of LBM and bone-mineral density. This benefit accrues for individuals with type 2 diabetes, as well as the general OW OB population. Before embarking on an exercise program, OW OB individuals with type 2 diabetes should be assessed as to the need for exercise stress testing (46), according to the discretion of their primary-care physician. Once readiness for training has been confirmed, a program of 30-45 minutes of moderate-intensity aerobic activity (40 percent to 60 percent maximum oxygen uptake or 50 percent to 70 percent maximum heart rate) three to five days per week is typically recommended with a gradual increase in duration and frequency of the activity (8, 47). For sedentary individuals who are quite inactive at the onset, the initial exercise should be of short duration and allow for a gradual progression to the target duration and...
Many people still believe that to lose weight you need to focus on daily aerobics. That's old school. The key to permanent, long-term fat loss and weight control is with strength training. Muscle requires more calories (energy) to sustain itself, so the more muscle you have, the more calories you're going to burn. Even while you're sleeping Aerobics does little if any muscle building. But it's a great supplement to your strength training, to aid in more calorie burning.
Implement more flexibility sessions into your workout. A word of caution warm up with 5-10 minutes of aerobic activity, then get down to business with your workout. Stretch AFTERWARDS. Why Stretching cold muscles is like taking a cold ruler out of the freezer, bending it just a little, and it SNAPS almost immediately. When you're done working out, blood is flowing, your muscles are extremely warm, and joints are lubricated. Aerobics become a little more important now, for your heart's sake. Continue doing your daily aerobics just add 10-15 minutes to each session. Stay active with gardening, bicycling, swimming, and dancing.
Do your strength training. Keep up with your aerobics. Balance and spread out your meals. Muscle tone is MUCH more attractive than low body weight with flab. Focus on how wonderful being healthy and strong FEELS, the things you're able to do now that you weren't able to do before because you were out of shape, the more you're getting out of life.
Body fat comes off MUCH FASTER when you incorporate strength training into your routine. And maybe your walking (or other aerobic activity) is too leisurely. Pick it up Challenge yourself Stick with these Big 3 of strength training, aerobics, and healthy eating - even for ONE week - and you'll definitely FEEL tons better.
Aerobics Exercise should take place most days and include a warm-up period, the exercise itself, and then a cooling-down period. To warm up before exercising, do stretching exercises slowly and in a steady, rhythmic way. Start at a medium pace and gradually increase it. Next, begin jumping rope or jogging in place slowly before starting any vigorous activities to ease the cardiovascular system into the aerobic exercise. The exercise part of the session should burn at least 300 kcalories, which can be achieved with 15 to 30 minutes of aerobic activity in the target zone or 40 to 60 minutes of lower-intensity activity, such as leisurely walking. After exercising, slowing down the exercise or changing to a less vigorous activity for 5 to 10 minutes is important to allow the body to relax gradually.
You may have been told that to drop the pounds you need more aerobics. But if you want to take your aerobics to a higher level, you need better-conditioned muscles. Then you can handle your walking, swimming, biking, gardening, and housework with more intensity and less fatigue. How do you do that That's right strength training.
You'd think that 30 minutes would be enough exercise for one day. After all, that's how long aerobics videos last, how aerobic machines are generally programmed, how long you have time at your lunch hour to break a sweat. Even our Surgeon General recommends 30 minutes of physical activity daily. So if 30 minutes a day is the ticket, why are so many people having trouble losing weight
Just keep doing your strength training. If you're just starting now, GOOD FOR YOU. If you don't use it, you lose it. You'll start seeing attractive muscle appearing in just a few weeks. Plus, you know how important muscle is in increasing your metabolism. And aerobics helps to burn even more calories.
Building a leaner, energized, shapely body is not an event it's a PROCESS. You don't just get to a certain weight, and that's it - you continue to challenge your mind and body to stay in peak condition. You are always experimenting with new and better ways to be at your best, otherwise you'll quit. If you've exhausted a particular training routine, move on to the next. Same with nutrition, aerobics, stretching, alternative medicine, etc.
Some caution should be applied, however, to the type of activity a pregnant woman chooses. Contact sports and movements involving rapid directional changes and jarring motions should be avoided. Exercise such as low impact aerobics, walking, and swimming is considered safe during pregnancy. However, a female must pay particular attention to her energy consumption and monitor her body weight and hydration status.
Your best bet to combat this situation is to continue exercising daily and eating as healthy as possible. Strength training is the best for metabolism-boosting, lean muscle. Aerobics will burn extra calories and promote healthy lungs and heart. A little spread is inevitable, but you can make it virtually unnoticeable. MUSCLE Muscle is the most metabolically active tissue in the body, so the more you have, the higher your metabolism will be. Challenge that body every time you work out to continue building and toning. Eat small, frequent meals to keep it in high gear. Take your nutritional supplements to help maximize your metabolism. Supplement your strength training with aerobics.
A concern about some form of overweight is common in most sports events where certain weight categories are in place (Table 1). Wrestling, particularly, has been subject to a great number of studies that have dealt with body composition, eating habits and weight loss regimens. A number of these studies have focused on the impact that rapid weight loss may have on various physical performances parameters. Some excellent reviews and discussions can be found in references 382-386. Basically the following findings have been reported. The primary methods of weight loss are diet manipulation by using well balanced diets, fasting and reduction or elimination of fluid intake. Other measures are aerobics to reduce body fat, dehydration via thermal exposure (sauna, hammam) or exercising in nylon suits or multiple layer clothing. The use of diuretics, laxatives, colon cleaning procedures and very low caloric diet (VLCD) products has also been reported. Some reports mention that a low percentage...
Numerous meta-analyses of the effect of aerobic exercise on blood pressure have been published, and the results have been consistent. Fagard18 performed a metaanalysis on 44 RCTs and concluded that aerobic exercise reduces blood pressure and that the lowering effect was greater in hypertensives (-7 -6 mm Hg) than normotensives (-3 -2 mm Hg). Further, he concluded that the evidence in support of these findings achieved the highest level of confidence rating, i.e., a Category FIGURE 4.1 Prevalence of individual risk factors before and after 20 wk of aerobic exercise training in the HERITAGE Family Study among 105 participants with the metabolic syndrome at baseline. *P 0.05 pretraining versus posttraining.

Ever rack your brain over a difficult problem for days, only to have the perfect answer jump into your head during an intense aerobic workout There's a growing body of evidence that suggests that aerobic exercise may boost brainpower, stimulate creativity, and increase intellectual capacity.
Despite OVERWHELMING evidence to support that weight training (at ANY age) can stop and even reverse this deterioration, most Americans who begin an exercise program choose more aerobic activity and neglect the muscle-saving, metabolism-boosting, fatigue-fighting strength training. Excessive aerobic exercise can actually waste away muscle, making you a skinny-fat person.
Many people engage in regular aerobic exercise such as running, cross country skiing, bicycling, rowing, fast walking, roller blading (in-line skating), distance swimming, and health club aerobic programs. During these activities the resistance against movement is not as great as weight training and the activity is sustained for 15 minutes or longer. Because muscle energy is generated by burning fat and carbohydrate in oxygen required processes mostly, these forms of exercise are termed aerobic. And, because the heart and blood vessels are responsible for delivering the oxygen-endowed blood to muscle, these types of activity are also called cardiovascular exercise.
Strength training makes you stronger, so you can do more vigorous tasks without undue muscular fatigue. Aerobic exercise conditions your heart and lungs, delivering nutrient-rich blood to working muscles and organs. Ultimately doesn't have to work as hard just to pump blood.
During prolonged aerobic (cardiovascular) exercise, muscle protein is broken down and amino acids, mostly alanine and glutamine are released into the blood. Alanine is one of the principal amino acids used to make glucose in the liver and the new glucose can help maintain blood glucose levels and fuel muscle during long aerobic exercise bouts. This process is
Women can actively engage in moderate exercise during lactation without affecting milk production, milk composition, or infant growth 15, 16 . Lovelady et al. demonstrated that overweight sedentary lactating women randomized to a regimen of reduced energy intake (-500 kcal day) and aerobic exercise (45 min 4 days each week) had babies that grew similarly to those of women who were not on an energy restricted diet and exercised once or never per week 15 . Aerobic exercise in this study consisted of walking, jogging, and dancing at 65-80 of maximum heart rate. The duration of exercise was initially 15 min, increased by at least 2 min each day until the women were exercising for 45 min at the target heart rate. There is some evidence that exercise in the absence of energy restriction will not promote weight loss postpartum, and diet restriction alone results in a greater percentage of lean body mass loss compared to exercise in combination with energy restriction 16, 17 .
Physical activity is recognized as one factor that affects polyunsaturated fatty acid status.5 Physical activity per se induces changes in the phospholipid fatty acid composition of muscle membranes.5,95 The effects of an aerobic exercise program (55 VO2 peak) on phospholipid fatty acid composition of ro-3 and ro-6 fatty acids in the skeletal muscle have been examined in sedentary subjects.95 Six weeks of physical training showed changes in the levels of ro-3 (EPA, DHA, and docosapen-taenoic acid) fatty acids, decreased the proportion of ro-6 (linoleic acid, dihomo-y-linolenic acid, and arachidonic acid) fatty acids in muscle phospholipids, and reduced the ro-6 to ro-3 ratio.96 Similar results were reported by Helge et al.95 when investigating the effect of endurance training of the knee extensor of one leg for 4 weeks on the muscle membrane phospholipid fatty acid composition. After 4 weeks of training, the phospholipid fatty acid contents of oleic acid and DHA were higher in the...
A level, indicating that the conclusion was based on a rich body of data from well-designed, randomized clinical trials providing a consistent pattern of results. In addition to this general finding, this report looked at the effects of the individual components of exercise training intensity, frequency, and individual session duration. Fagard concluded that the beneficial aerobic-exercise effect was not dependent In a somewhat larger and more recent meta-analysis, also on RCTs (n 54), Whelton et al.32 concluded that aerobic exercise decreased diastolic and systolic blood pressure in both hypertensive and normotensive individuals. The effect was somewhat larger in the hypertensives (-5 -4 mm Hg) than the normotensives (-4 -2 mm Hg). Additional analyses revealed that the beneficial exercise effects were observed in Caucasians and Asians for both systolic and diastolic blood-pressure reductions. In African Americans, a significant beneficial effect was found for systolic, but not...
Period. Keep your waist slim by FIRST and foremost, changing your diet. Second, supplement your strength training with aerobic exercise for more calorie burning. Third (and you probably thought this should be first), do your ab training daily.
Situations can occur that increase the use of body protein for energy. Eating too few calories or fasting increases the reliance on body protein as an energy source. In these situations the level of circulating glucagon and cortisol increase. Cortisol, the stress hormone, will promote the breakdown of our body proteins to amino acids. Meanwhile, both of these hormones promote the conversion of amino acids to glucose in our liver which is released to serve as fuel. The amount of amino acids used to make glucose is related to the length and degree of caloric restriction and the intensity and duration of exercise. Simply stated, as glycogen stores in the liver and muscle become depleted, as in prolonged fasting and aerobic exercise, the reliance upon amino acids to make glucose increases.
A nonessential AA, alanine is produced in large amounts within skeletal muscle during exercise. Much of the amino nitrogen released from BCAA metabolism in muscle is utilized to produce alanine via transamination of pyruvate. During states of stress such as aerobic exercise, there is a net flux of alanine from muscle tissue into the blood for transfer of nitrogen from skeletal muscle to the liver. In the liver, alanine is deaminated back to pyruvate and ammonia. Pyruvate can enter liver gluconeogenesis for the production of glucose, and the fate of ammonia is mainly in the formation of urea for excretion via the kidneys. This process, often called the glucose-alanine cycle, allows the skeletal muscles to eliminate ammonia via a gluconeogenic precursor that the liver can return to the circulation as glucose to support continued muscular contractions.11 To keep up with glucose demand in times of physiological stress such as exercise, alanine can become vital in helping to maintain blood...
There are only a couple of conditions where carnitine supplementation may actually act to increase concentrations within the muscle. These circumstances include a supraphysiological dose (100 mg kg body weight). In addition, those individuals who are carnitine deficient will benefit from supplementation. Specifically, this is because those individuals already have low carnitine concentrations and supplementation will allow for the accumulation of the necessary carnitine content within the muscle to perform. These studies1245-47 emphasize that there is adequate carnitine within the muscle mitochondria to oxidize lipids, and furthermore that a carnitine deficiency will not occur as a result of aerobic exercise. In addition, when muscle carnitine levels were compared to plasma levels, it was found that the carnitine metabolic state, associated with exercise, was very poorly reflected by changes in both the plasma and urine.46
Studies have shown that exercise can have a direct effect on preventing heart disease, cancer, and other causes of premature death. Furthermore, participation in regular physical activity may reduce the rate of occurrence of these maladies. An inverse relationship exists between disease and exercise, meaning that with increased levels of physical activity there is a decreased prevalence for certain diseases. Currently, there is strong evidence that exercise has powerful effects on mortality, CAD (including blood lipid profiles), and colon cancer. Research has also confirmed that aerobic exercise can reduce high blood pressure, obesity, type II diabetes, and osteoporosis. In addition, stroke and several types of cancer (such as breast, prostate, and lung cancer) can also be reduced with regular physical activity.
Caffeine has long been considered a stimulant and is used by many individuals in normal daily life as well as by athletes. Caffeine and related substances are found naturally in foods and beverages, such as coffee, teas, and chocolate and as part of recipes, such as in various soft drinks. Coffee contains caffeine whereas tea contains theophylline and chocolate contains theobromine. These factors are considered stimulants as they impact the central nervous system and increase alertness, which alone can improve the enjoyment of exercise and help some people perform at a higher level. Caffeine and related substances also enhance and prolong the effects of certain hormones such as glucagon and epinephrine in fat tissue. If fat release is increased and made more available to muscle then more fat might be used during aerobic exercise and improve performance and help lean the body.
While a little bit of dietary fat can be used for energy very early during a meal as the body shifts from a fasting to a fed state, by and large dietary fat is destined for storage or put to use in other ways. By design, fat cells will store loads of fat and insulin promotes this activity. On the contrary, skeletal muscle cells and the heart have a limited ability to store fat. However, the amount of fat that skeletal muscle can store can be increased by aerobic training (such as running and biking). The importance of this fat is related to performance, as during exercise this fat is readily available to the muscle cells in which it is stored. In addition, aerobic exercise training also promotes adaptations in muscle cells, making them better fat burners during and after exercise. More on the relationship between exercise and fat burning and storage will be discussed in later chapters.
Physical activity has beneficial effects on both plasma HDL cholesterol and triglyceride concentrations as well as LDL and HDL particle size.43 A meta-analysis on the effects of aerobic exercise on lipid profiles of adults at the age of 50 years and older reported that aerobic exercise increased plasma HDL cholesterol, creating a more favorable ratio of plasma total cholesterol to HDL cholesterol concentration.44 The magnitude of increased plasma HDL cholesterol concentration following aerobic exercise training may partially depend on exercise intensity, frequency, duration of the individual exercise session, and the length of the training period. It is suggested that changes in plasma HDL cholesterol levels occur incrementally and reach statistical significance around a distance of 7 to 10 miles of moderate-intensity exercise per week, or equivalent to 1200 to 1600 kcal.45 Resistance exercise has been shown to reduce plasma LDL cholesterol concentration.43
However, not all aerobic activities are the same. Some programs are better than others, especially for weight control. The general recommendation for aerobic fitness (NOT weight loss) is 20-40 minutes of moderate activity 3-5 times a week. So you're going to divide your aerobic workout into 15 minutes spent on 3-4 different exercises for a great alternative to doing the same darn thing on ONE machine every time you work out.
Twenty to 30 miles per week is a good training distance for an intermediate runner (Table 6-3). As a rule, your risk of injury sharply increases as your running mileage increases. So, if running for fitness rather than competition, keep your weekly mileage below 30 miles. Beyond this, your injury risks far outweigh any additional fitness benefits. Cross-train to work on aerobic fitness without running more than 30 miles.
Now you are ready to design your aerobic workout When designing a cardiovascular routine there are a few questions you must answer. These are Walking, running, and swimming all provide excellent aerobic workouts. These three types of exercise will be discussed in this chapter for two reasons 1) walking and running are the most common types of exercise that people engage in, and 2) all three modes of exercise can be used to test your level of physical fitness on the Navy PRT tests.
Increase in heart rate is not the training stimulus it is only indicative of the oxygen consumption required during the exercise. If an increase in heart rate was all that was needed to increase aerobic capacity, then watching a thrilling movie while sitting on your favorite couch would provide an aerobic training benefit
To become more muscular and lean, people combine weight training with dietary control. In addition, integrating aerobic training will certainly be beneficial. It's not important not to drastically restrict energy intake, if at all. Drastic energy restriction can place an extra demand upon skeletal muscle to provide amino acids for energy, thus counteracting resistance training to some degree. Thus drastic energy restriction and weight training may create a futile cycle as muscle breakdown contradicts muscle hypertrophy.
Throw in some intervals with your aerobic training. Change your strength training routine every few weeks. Do a major overhaul - create an entirely different routine with exercises you haven't done in a long time. Bike for a couple of weeks, then walk for a couple, then do the ski machine or elliptical trainer for a couple. You eliminate boredom, too.
It is common to hear fitness professionals and medical doctors prescribe low to moderate intensity aerobic training (cardio) to people who are trying to prevent heart disease or lose weight. Most often, the recommendations constitute something along the lines of perform 30-60 minutes of steady pace cardio 3-5 times per week maintaining your heart rate at a moderate level . Before you just give in to this popular belief and become the hamster on the wheel doing endless hours of boring cardio, I'd like you to consider some recent scientific research that indicates that steady pace endurance cardio work may not be all it's cracked up to be.
It is widely accepted that chronic-endurance aerobic training can induce changes within the skeletal muscle to enhance performance and increase endurance. Some of these changes include increased capillary density, increased enzymatic concentration, and an increase in the size and number of mitochondria. This is associated with an increased ability of the athlete to oxidize FAs, in the form of intramuscular trigylcerides, for fuel. This phenomenon has led researchers to analyze the potential changes that might occur with carnitine concentrations in all pools, including urinary excretion, plasma, and muscle.
If you prefer to do your aerobic conditioning indoors and are willing to spend a little, you've got the old stand-by, the treadmill. Walking is still the 1 aerobic activity year after year. And why not It's easy, you burn calories, and you can increase your pace as you get more fit.
Although confined spaces can limit your training options and make you feel less than enthusiastic to train, you need to remain physically active. Stopping all physical training results in a rapid decline in muscle strength and endurance, flexibility, and aerobic conditioning (see Chapter 4). One option to boost morale and increase participation in physical training during deployment is to help organize and participate in team competitions such as mini-triathlons (perform any three aerobic exercises back-to-back for the best time) and sports days. Finally, you may feel that the biggest barrier to working out when deployed is time limitations. In actuality, it requires less time to maintain fitness levels than to increase fitness levels. Though not ideal, you can maintain your fitness level by working at your usual intensity fewer times per week and for shorter durations than what is required to improve your fitness level. A minimum of one strength session, which includes exercises for...
Since most daily activities are aerobic in nature, improving the delivery of oxygen to the muscles will improve your work performance. On the other hand, a sedentary lifestyle decreases the heart's ability to circulate blood and oxygen. So, view your heart as an aerobic muscle that must be conditioned for optimum functional health and fitness throughout your life. Even though some people are born with higher aerobic capacities than others, everyone will benefit from aerobic conditioning.
Evans and his colleagues have developed an approach for managing sar-copenic obesity through regular strength and aerobic conditioning exercise. A controlled trial found that strength training improved functional capacity and muscle physiology, and reduced sarcopenia in 90-year-old men.47 Physiology research has demonstrated that properly prescribed and implemented resistance training increases the production of anabolic hormone messengers and reduces inflammatory mediators.
It is not necessary to do aerobics to experience the health benefits of exercise. All that you have heard about heart rate and cardiovascular effectiveness of the exercise is only partially true, because much of the information is age-related. In fact, the elderly could be significantly harmed by the physical demands of aerobic exercise.
But some of my clients complain to me that they have lost no weight despite hours of working out. That often happens because they are rewarding themselves afterward with generous amounts of calories that replace all they burned off. They may have exercised for 30 minutes and burned off 300 calories, but then they consumed 300 calories of recovery food in 3 minutes. Despite popular belief, appetite tends to keep up with your exercise load (except in extreme conditions). The more you exercise, the hungrier you will eventually become, and the more likely it is that you will eat enough to replace the calories you burned off. Nature does a wonderful job of protecting your body from wasting away, particularly if you are already lean with little excess fat to lose (Woo, Garrow, and Pi-Sunyer 1982 Woo and Pi-Sunyer 1985). Another factor that influences the effectiveness of exercise as a means to lose weight relates to the toll of exercise on your total daily activity. Some avid exercisers put...
What are aerobics If you think that aerobics are just jumping around to bad disco music, dust off your sneaks you're way behind the times. The term aerobic literally means with air.' Therefore, the exercises in which your muscles require an increased supply of air (more specifically, the oxygen within air) are termed aerobic. Aerobic activity is also known as cardiovascular activity (or cardio) because it most definitely challenges your heart and lungs. Think about this When you jog, the large muscles of your lower body are continuously working over an extended period of time and therefore require more than their usual supply of oxygen. Because your heart and lungs are the key players in retrieving and circulating oxygen, they go into overdrive to increase oxygen delivery. Therefore, in addition to working out the large exterior muscles, aerobic activity also provides one heck of a workout for your heart and lungs. Normally, aerobic exercise should last 20-60 minutes, depending upon...
Trick keep your strength training workouts between 20-40 minutes, and aerobic training to 15-20 minutes. If you don't have time for both strength and aerobic, DO THE STRENGTH TRAINING. Better muscle means less fat, less weight, and a dynamite body. No need for the 90-minute workouts. Guys, split your body in half do half three days a week, and the other half the other three days. Or, you can lift 4 days a week, and do your aerobics the other two. Gals, do abs and lower body EVERY DAY. Do your upper body 2-3 times a week. For the most part, your workouts will be about 30 minutes.
Cross-sectional studies also suggest a dose-response relationship between amount of exercise and HDL-C concentrations. However, exercise-training studies, according to Durstine and Haskell, have not been as consistent, as many studies have reported a significant training benefit on HDL-C levels, while many other studies did not find the effect to be significant. Leon and Sanchez,37 in their meta-analysis, reported a marked inconsistency of the effects of aerobic-exercise training on blood lipids in general, and they suggested that the most frequent finding was of a significant (P 0.05) increase in HDL-C. However, this significant beneficial effect was reported in only 24 of the 51 studies (47 percent) included in the review. The exercise-induced change in HDL-C ranged from a decrease of 5.8 percent to an increase of 25 percent. Nevertheless, overall there was an average increase of 4.6 percent across the studies (P 0.05).
Note that the duration of this workout is dependent on the number of exercises that are performed and the length of the aerobic exercise. Perform the number and duration of exercises that are appropriate for your fitness level and adjust the routine as your fitness improves. Note that the duration of this workout is dependent on the number of exercises that are performed and the length of the aerobic exercise. Perform the number and duration of exercises that are appropriate for your fitness level and adjust the routine as your fitness improves. Worksheet B-1. Aerobic Exercise Log
The best way to prevent weight gain is to exercise and maintain an active lifestyle. Research suggests that women who exercise do not gain the weight and waist of their nonexercising peers (Sternfeld et al. 2004). The optimal exercise program includes both aerobic exercise (to enhance cardiovascular fitness) and strengthening exercise (to preserve muscles and bone density). The book Strong Women Stay Slim by Miriam Nelson is a good resource for helping women develop a health-protective exercise program.
The FEP should be geared to meet the deficiency of the member. If the PRT failure was for body fat, a longer duration exercise session would be more beneficial for losing body fat. If the PRT failure was for failing the run, then the member should be running 1.5 miles or longer to build endurance. Many people who are overweight may not be able to run for a 40-minute period of time. Brisk walking (in your target heart rate range) is an aerobic exercise. A 12-minute mile is a good pace, however you should be working towards a 10-minute mile. Believe it or not, many experienced runners have started with a good walking program. Always keep in mind as you progress in your walking program, you should be covering greater distances in the same amount of time. Regardless of whether you are walking or running, the key is level of exertion. You should strive to maintain a target heart rate of 65-80 percent of your maximal heart rate during your entire aerobic exercise session. Navy policy...
As you can plainly see, resistance training is essential to losing fat and maintaining lean body mass (muscle). In fact, it's just as important as aerobics if not more so. The truth is if a person has limited time for either weight training or aerobics, I would recommend the weight training over the aerobics any day. Several recent studies have found that resistance training maintains resting metabolic rate (RMR) better than aerobics (Bryner, et al, 1999). As well studies have shown resistance training is far superior to aerobics for maintaining the metabolically active tissue we need (muscle ) for a superior fat burning metabolism while trying to gain muscle mass. Weight lifting is the only exercise that has been proven to keep a person's metabolism elevated over long periods of time. Resistance training does burn approximately the same number of calories as if you went for a run or hopped around in an aerobics class. But the calorie burning and metabolism raising effects of weight...
Pregnancy is associated with profound respiratory changes minute ventilation (tidal volume x breaths minute) increases by approximately 50 , primarily as a result of increased tidal volume (volume of gas inhaled and exhaled during one respiratory cycle) 30, 31 . Because of the increased resting oxygen requirements and the increased work of breathing caused by pressure of the enlarged uterus on the diaphragm, there is decreased oxygen availability for performance of aerobic exercise during pregnancy. Thus, both workload and maximum exercise performance are decreased 31, 32 .
Do aerobic exercise regularly try to maintain your exercise intensity (see Chapters 4,5,6). Do speed work in addition to aerobic exercise only if you want to maintain performance-related fitness or participate in competitive sports (see Chapters 4,5). Cross-Training - No specific exercise is better than another to offset all the health and fitness changes mentioned. However, many of these concerns can be addressed by cross-training, or altering the types of exercises you perform, throughout the week (see Chapter 5). By cross-training, you can improve and maintain your aerobic fitness while recovering from intense workouts or while taking a break from weight-bearing exercises. This will help prevent overtraining and overuse injuries (see Chapter 13) while you remain physically active. So, consider making cross-training a regular practice in your exercise routine, if it is not already.
Findings regarding the ergogenic efficacy of creatine supplementation.71 Creatine supplementation has no effect on aerobic exercise metabolism and performance.66,67 At this point, there is no justification for creatine supplementation by vegetarian athletes involved in power sports. Sports in which performance is subjectively scored (dance, figure skating, diving, gymnastics, aerobics)
This time, within two months after taking Nystatin and vitamins, and doing aerobics, and going to an emotional therapist to make sure that I got everything worked out, I was a different person. I felt so totally different, that it gave me the vantage point to look back over the previous 20 years of my life and say, Oh, if only I had known all of this then, I wouldn't have done all of that. I had spent my life running down the wrong roads. And it was such a relief because it allowed me to really begin to live. Now I have my little ritual. I take my vitamins and do my aerobics, and make sure that I keep my house environmentally clean of gases and pollutants that exacerbate the condition. The change in how I felt was like going from 2 percent to 98 percent well. It was so dramatic.
Fitness improves when the body has more muscle and less fat. (Okay, you already knew that.) The way to improve your muscle fat ratio is with a focus on strength training, supplemented with aerobic conditioning. Strength training increases metabolism, while aerobics burns extra calories and fat.
If you're only doing three days a week of exercise, you're looking down the road of frustration, anger, and disappointment - and lack of progress. Bump it up to 4, 5, even 6 days a week. Your body is designed to move, so use it or lose it. 20-40 minutes strength training, 15-20 aerobics. Even one extra workout day will make a difference in weight loss.
During the postpartum period, many women are eager to lose weight and improve muscle tone. Of concern to many women is whether an energy deficit will affect the quality of breast milk, thus impairing infant growth. Aerobic exercise performed four to six times per week at a moderate intensity of 60-70 maximal heart rate for 45 min per day does not appear to affect breast milk volume and composition 74 . The Institute of Medicine recommends lactating women should lose no more than 2 kg month 75 . However, one study reveals that short-term weight loss of approximately 1 kg week through a combination of aerobic exercise and dietary energy restriction helped preserve lean body mass without affecting lactation performance 76 .
Ideally, for the joint purposes of enhancing weight reduction, preserving and possibly building lean mass, and improving cardiovascular and metabolic parameters, an optimal exercise regimen should incorporate a mixture of aerobic and resistance training, as the two types of exercise might have separate and different, as well as interactive, protective effects for the individual with type 2 diabetes. An exercise regimen might, for example, include some form of aerobic exercise three times weekly, supplemented by resistance training twice per week.
Capacity, probably by its incorporation into membranes and its effect in the increase of the deformability of red blood cells, enhancing oxygen transport and then improving exercise performance. However, other studies have shown contrasting results. Therefore, enhanced aerobic exercise performance has not been clearly demonstrated, and more research is needed to elucidate the effect of supplementation. Based on available information, ro-3 fatty acids supplementation seems to reduce the severity of EIB in athletes by reduction of several inflammatory mediators. Additional research is needed in this area, as the research on supplementation of ro-3 fatty acids on nonathlete individuals does not show enough evidence to form a clear conclusion.
Aerobic exercise does require oxygen for energy. This is observed during exercise that is less intense but of longer duration. This energy system is primarily used during events lasting longer than several minutes, such as a two-mile run or the Tour de France bicycle race. The potential does exist that one can use both systems, as in soccer, where a match requires ninety minutes of continual activity with short intense bursts of effort.
Burning only an extra 100 calories a day by walking briskly for about 20 minutes will lead to a weight loss of about 10 pounds a year, while burning an extra 300 calories by walking briskly for about 60 minutes a day will lead to a weight loss of about 30 pounds. Physical activity contributes to weight loss, decreases abdominal fat, increases cardiorespiratory fitness, and helps with maintenance of lost weight. Any aerobic exercise, such as swimming, bicycling, jogging, skiing, or dancing, leads to these benefits, but for most obese people brisk walking seems to be the easiest activity to do. Other forms of exercise, such as resistance training or lifting weights, can also be helpful in a weight loss program. Finding ways to be more active every day, such as walking up a flight of stairs rather than taking the elevator, or walking somewhere rather than driving, can help a person burn calories without much effort.
Using running as an example (any aerobic exercise applies), set your pace at about 60 of your max heart rate. It would be an EXCELLENT idea for you to invest in a heart rate monitor for accurate readings. HILLS. Using hills in your aerobic training calls for the muscles in your legs to work harder, making them stronger and more durable. Once a week run a hill up and down several times. Use the interval training principle so you're not killing yourself, and your body won't punish you days later.
For example, one recent study evaluated the effects of 5 months of Vitamin E (alpha-tocopherol) supplementation on physical performance during aerobic exercise training in 30 top-class cyclists. The study found the plasma Vitamin E concentration increased significantly in the vitamin E-supplemented group, whereas the placebo group showed a trend toward decrease.
The last T in FITT refers to the type of exercise performed. To increase aerobic fitness, exercise should be a low-resistance, high-repetition activity (e.g., biking) that trains the heart and the muscles to use oxygen more efficiently. To choose the best exercises for you, consider the following Table 5-2. Examples of Aerobic Exercise Table 5-2. Examples of Aerobic Exercise Swimming, water aerobics
People often ask me what kind of home equipment to purchase. Put simply, buy what you'll actually use. Everybody knows you need a combination of strength training and aerobic conditioning. So, you'll definitely use some dumbbells and barbells and an adjustable bench for strength training.
Ability to lose weight - and keep it off. Yes, exercise burns calories, increases your metabolism and energy, and develops lean muscle mass. But just as important, exercise catapults your self-esteem, which makes you more likely to do other things to take care of yourself, like eat less. Get moving means strength training AND aerobic conditioning.
If you're pretty overweight, or deconditioned, start slowly to improve your strength and aerobic conditioning level. You're still challenging your body, but in this case you're using common sense. After a couple of weeks, you should be able to kick your fitness program into high gear.
In the resting muscle cell a relatively high percentage of the overall energy production stems from FA oxidation. This high contribution is either maintained or becomes slightly reduced during light aerobic exercise. However, with high exercise intensities there will be a more pronounced shift from fat as energy source to CHO, particularly at intensities above 70-80 of VO2max. This points to the fact that there are limitations to increase the FA oxidation rate in order to replenish sufficient ATP to cover the needs. Several theoretical explanations have been given for this exercise induced shift from fat to CHO
Unfortunately, too much attention has been focused on aerobic exercise. A commonly held belief is that unless you maintain a specified heart rate for a particular period of time, little good comes of the effort. As a result, many people just give up after a brief foray into the fitness jungle and resume a sedentary lifestyle. Fortunately, growing evidence indicates that moderate exercise, such as brisk walking or a moderate workout with an exercise machine, can impart the most healthful benefits. The most important consideration is that, whatever exercise you choose, it must be done on a regular basis and for at least forty-five minutes per session. The important thing to remember is that the number of free radicals generated during exercise depends on the intensity of the exercise and its duration. Recent studies on intensely training athletes have demonstrated a remarkable increase in free-radical generation and lipid peroxidation. Fortunately, these harmful effects can be reduced...
