Summary

The aim of this study is to determine whether the distribution of internal load predicts the distribution of muscle hypertrophy among hamstring heads after a 10-week resistance exercise program. The hypothesis is that the distribution of internal muscle load among the hamstring is related to the distribution of muscle hypertrophy.

Detailed description

It is well accepted that muscle stress (mechanical and/or metabolic) is the major way to induce muscle hypertrophy. While this link between muscle stress and hypertrophy is pivotal is sport training, prevention and rehabilitation, it remains poorly understood. To date, the only indirect evidence of relationship of muscle stress and muscle hypertrophy is the similar patterns (from independent studies) between muscle damage and hypertrophy within quadriceps (i.e., rectus femoris (RF) \> vastus (VL) = vastus medialis VM), hamstring, and triceps surae. However, muscle damage is an indirect proof of muscle mechanical stress. With the quantification of internal muscle load, it is interesting to determine whether the muscle that receives the larger stress exhibits the larger hypertrophy.
