Effects of Training Frequency on Strength Maintenance in Pubescent Baseball Players

Abstract

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.
