Exercise-induced hormone elevations are related to muscle growth. J Strength Cond Res 31 (1): 45–53, 2017—Partial least squares regression structural equation modeling (PLS-SEM) was used to examine relationships between the endocrine response to resistance exercise and muscle hypertrophy in resistance-trained men. Pretesting (PRE) measures of muscle size (thickness and cross-sectional area) of the vastus lateralis and rectus femoris were collected in 26 resistance-trained men. Participants were randomly selected to complete a high-volume (VOL, n= 13, 10–12RM, 1-minute rest) or high-intensity (INT, n= 13, 3–5RM, 3-minute rest) resistance training program. Blood samples were collected at baseline …
