Abstract This study investigated the effects of varying strength exercises and/or loading scheme on muscle cross-sectional area (CSA) and maximum strength after four strength training loading schemes: constant intensity and constant exercise (CICE), constant intensity and varied exercise (CIVE), varied intensity and constant exercise (VICE), varied intensity and varied exercise (VIVE). Forty-nine individuals were allocated into five groups:
D
CICE, CIVE, VICE, VIVE, and control group (C). Experimental groups underwent a twice a week training for 12 weeks. Squat 1RM was assessed at baseline and after the
TE
training period. Whole quadriceps muscle and its heads CSA were also obtained preand post-training. The whole quadriceps CSA increased significantly (p
