Muscle thickness (MT) of the elbow flexors, elbow extensors, mid-thigh, and lateral thigh was assessed using B-mode ultrasound. Upper-body muscle endurance was assessed by performing the bench press to failure at 50% of 1RM.
Maximal strength was assessed using the one repetition maximum (1RM) tests in the leg press and bench press.
#Powerflex isometric workout iso
A 2-min rest interval was afforded between sets the ISO group performed iso-holds for the first 30 s of each rest interval and then recovered for the final 90 s. Three sets of 8–12 repetitions were performed per exercise. Training for both routines consisted of three weekly sessions performed for 8 weeks. Twenty-seven resistance-trained male volunteers were randomly assigned to either a traditional group (TRAD) that performed a hypertrophy-oriented RT routine with the rest intervals spent passively ( n = 13) or to a group that supplemented traditional RT with iso-holds (ISO) for the working muscle group between each set ( n = 14). We aimed to investigate the effects of resistance training (RT) combined with no-load isometric actions (iso-holds) during the inter-set recovery period versus RT that involves passive inter-set rest on muscular strength, muscular hypertrophy, and muscular endurance in resistance-trained men. 7Department of Statistics, Northwestern University, Evanston, IL, United States.6Department of Biomedical Engineering, Northwestern University, Evanston, IL, United States.5Department of Health Sciences and Human Performance, The University of Tampa, Tampa, FL, United States.
