Body composition, stress-related parameters, and visual function during the 12-week intervention
muscle hypertrophy
Generally, the adaptation of skeletal muscles to resistance training results in an initial increase in muscle strength, followed by muscle hypertrophy with an extended training period. Therefore, we conducted trial 2 with an intervention period of 12 weeks. Stress-related parameters in saliva and visual ability were also examined because the outcomes of trial 1 and previous studies suggested that matcha may suppress the stress response [Muscular, stress, and visual parameters in trial 2. Muscle weight (Among stress-related parameters, the salivary cortisol secretion rate showed a trend indicating interaction (
