The purpose of this study was to investigate the effect of combined lin-ear and nonlinear periodic training on physical fitness and competition times in finswimmers. The linear resistance training model (6 days/week) and nonlinear underwater training (4 days/week) were applied to 12 finswimmers (age, 16.08±1.44 yr; career, 3.78±1.90 yr) for 12 weeks. Body composition measures included weight, body mass index (BMI), percent fat, and fat-free mass. Physical fitness measures included trunk flexion forward, trunk extension backward, sargent jump, 1-repeti-tion-maximum (1 RM) squat, 1 RM dead lift, knee extension, knee flex-ion, trunk extension, trunk flexion, and competition times. Body compo-sition and physical fitness were improved after the 12-week periodic training program. Weight, BMI, and percent fat were significantly de-creased, and trunk flexion forward, trunk extension backward, sargent jump, 1 RM squat, 1 RM dead lift, and knee extension (right) were sig-nificantly increased. The 50- and 100-m times significantly decreased in all 12 athletes. After 12 weeks of training, all finswimmers who partici-pated in this study improved their times in a public competition. These data indicate that combined linear and nonlinear periodic training en-hanced the physical fitness and competition times in finswimmers.
