Irises released into the bloodstream function to execute regulation of energy metabolism, triggering browning white adipose, which is useful mitochondrial biogenesis. The American College Sport Medicine (ACSM) recommends moderate intensity training with a frequency 3-5 times week, duration 20-60 minutes, using treadmill. St...

Resistance training (RT) is the main method of exercise for improving strength and skeletal muscle mass (i.e., muscle hypertrophy; ACSM, 2009). In order to promote such adaptations, high-intensity resistance training (HI-RT) with loads above 60% of one repetition maximum (1-RM) are typically recommended (ACSM, 2009). To further maximize increases in strength and muscle hypertrophy, it has been ...
