Abstract
Participants were 43 Navy men (.hivin.X [mean] age = 32.1 yr) assigned to 1 of 3 exercise training protocols: aerobic/circuit wt training performed at either 40 or 60% of determined one-repetition maximum strength or aerobic/calisthenic training. During the 10-wk study, each exercise group participated in 3 training sessions per wk performed on alternate days. Dynamic strength (both upper and lower) evidently increased for the aerobic/circuit wt training groups but not for the aerobic/calisthenic group. With the exception of bench press endurance for the aerobic/calisthenic group, all groups showed significant increases in muscular endurance and stamina. No significant changes were seen in static strength or flexibility in any of the groups. Subjects [in a 2nd study] were 87 male Navy personnel (.hivin.X age = 19.8 yr) receiving basic training at the Recruit Training Command, San Diego, CA [USA]. One company of recruits (N = 41) participated in an experimental aerobic/circuit wt training program at 70% of determined 1-repetition maximum. A 2nd company (N = 46) received the standard Navy recruit physical training program (aerobic/calisthenic training). During the 8-wk study, both groups participated in an identical running program performed 3 times/wk on alternate days. Additionally, aerobic/circuit wt training participants completed 2 circuits (1 circuit = 15 exercises) 3 times/wk on alternate days to running. Study findings show the experimental aerobic/circuit wt training program produced significantly greater dynamic muscular strength and muscular endurance changes than the standard aerobic/calisthenic program. Recruits following the standard training program showed decrements in several muscular strength and muscular endurance measures.
