The phenomena of muscle hypertrophy in response to overloading is under written. The purpose of this study was to assess the early changes in muscle size and architecture during a 35-day high-intensity resistance training (RT) program.

For the first time, results showed that increases in muscle size were detectable after only 3 wk of RT and that remodelling of muscle architecture precedes gains in muscle cross-sectional area (central and distal regions of the quadriceps femoris (QF). As muscle hypertrophy seems to contribute to strength gains, flywheel training has positioned itself as particularly effective for inducing these early structural adaptations.
