Background: Rhythm step training (RST) for sensorimotor dual tasks is in the spotlight as it provides physical activity that is fun and allows participants to express various and creative movements, although it lacks a scientific evidence base. Therefore, this study was to investigate how RST affects the physical and cognitive functions of adolescents. Materials and Methods: A total of sixty-six female middle-schoolers were divided into non-exercise group (control group, CON, n = 22), step training group (STG, n = 22), and rhythm step training group (RSTG, n = 22). To verify the combined effects of music-based rhythm and exercise, the program was conducted for 45 min/session a day, three times a week for 12 weeks. Results: RST scores increased significantly in the STG and RSTG compared to the CON after 12 weeks. Specifically, the Δ% of RST scores in the RSTG (11.44%) was higher than those of STG (9.01%) and CON (3.91%). By the end of the experiment, the power ( p < 0.001), agility ( p < 0.001), muscle endurance ( p < 0.001), dynamic or static balance ( p < 0.001), and gait velocity ( p < 0.001) of RSTG were significantly improved compared to the others. The Δ% of all variables in RSTG was higher than those of the CON or STG. In addition, the verbal memory ( p < 0.001) and attention ( p < 0.001) of cognitive function were significantly improved in RSTG. Specifically, there was more of an increase in Δ% of RSTG for verbal memory (7.52%) and attention (10.33%) than in the CON (verbal memory, 3.34%; attention, 5.83%) or STG (verbal memory, 5.85%; attention, 5.43%). Conclusions : This study confirms that RST had a positive effect on the physical and cognitive functions of female middle-schoolers. We propose that rhythmic exercise combined with music is beneficial for adolescents' physical and cognitive health.
