Fat tissue provides some protection to various tissues in the body. For instance, fat tissue around our internal organs provides some cushioning. This helps protect the organs against external trauma. Furthermore, the subcutaneous layer of fat storage also provides some cushioning, which protects muscle. Subcutaneous fat is not well vasculated, meaning that there aren't a lot of blood vessels in that tissue relative to other tissue. Meanwhile, skeletal muscle is heavily endowed with blood vessels which provide oxygen and energy nutrients during activity and exercise. In the absence of subcutaneous fat it would be easier to rupture smaller blood vessels in skeletal muscle, which then would be evident in bruises. As an example, prior to competition, bodybuilders will be very cautious not to bang into things or play contact sports (rugby, football, roller hockey, etc.). As they attempt to "lean out" for the competition, they reduce their subcutaneous fat to nadir levels, which would allow them to bruise more easily. This then would impact their aesthetic presentation during the bodybuilding competition.
