To examine the impact of 8 weeks of low-volume resistance training with or without personalized blood flow restriction on measure of muscle mass, strength, quality, and bioenergetics. We will use high-load resistance training as a reference control. We will measure muscle mass using Dual Energy X-Ray Absorptiometry, muscle strength using isokinetic testing. We will normalize knee extensor strength to lower limb lean mass to quantify muscle quality. We will also use near infrared spectroscopy and oxygen recovery kinetics to measure mitochondrial oxidative capacity in the vastus lateralis.
