Free Abstract This study investigated the effects of a high volume 5-wk weight training program and different exercise/rest intervals on measures of power, high intensity exercise endurance (HIEE), and maximum strength. Subjects, 33 weight trained men (M age 20.4±3.5 yrs), were divided into 3 equal groups. The groups used the same exercises and set-and-repetition scheme. Rest intervals were 3 min for Gp 1, 1.5 min for Gp 2, and 0.5 min for Gp 3. Pre/post changes were analyzed using G × T ANOVA. Peak power, average peak power, and average total work, as measured during 15 five-sec cycle max-efforts rides and the 1-RM squat, increased significantly (N = 33, p < 0.05). The vertical jump and vertical jump power index did not show a statistically significant change. The 1-RM squat increased significantly more in Gp 1 (7%) than in Gp 3 (2%). Data suggest that, except for maximum strength, adaptations, to short-term, high-volume training may not be dependent on the length of rest intervals. © 1995 National Strength and Conditioning Association
