This study examined the effects of training frequency on strength maintenance in 21 trained pubescent male baseball players (mean age 13.25 ± 1.26 yrs). The subjects completed 12 weeks of preseason, progressive strength training 3 days a week and were assigned to 1 of 3 experimental groups for an additional 12 weeks of in-season maintenance training. Group 1 (n = 7) lifted weights 1 day a week, Group 2 (n = 8) lifted weights 2 days a week, and a control group (n = 6) did not train during this 2nd 12 weeks. The preseason strength training program revealed significant increases (p < 0.05) for all groups in upper (bench press) and lower (leg press) body strength and dynamic upper body muscular endurance (pull-up). Following the 12-week in-season maintenance program, significant differences (p < 0.05) were observed between the control group and both training groups for the bench press. However, no significant differences were revealed between groups for the leg press or pull-up. It was concluded that for pubescent male athletes, a 1-day-a-week maintenance program is sufficient to retain strength during the competitive season.
