- Abstract
Introduction: Although the World Health Organization recommends 60 minutes of physical activity per day for children, approximately 80% do not meet this recommendation.1,2 Rhythm jump training (RJT), involving rhythmic jumping exercises, is aimed at increasing physical activity and improving motor skills; however, its effectiveness remains unclear. Objectives: This study was aimed to elucidating the effects of RJT on motor skills. Study design: We conducted a non-randomized comparative trial. Methods: Overall, 101 preadolescent soccer players attending soccer school once a week were included, with 79 individuals (age: 8.5 ± 1.6 years) ultimately participating after exclusions. The participants were divided into two groups, RJT group (n = 44, age: 8.3 ± 1.8 years) and CON group (n = 35, age: 8.7 ± 1.4 years). The RJT group performed six different RJT exercises synchronized to music at a tempo of 115-120 BPM for the initial 10 minutes of each 60-minute practice session once a week, totalling eight sessions. The CON group performed regular warm-up exercises. Motor skill performance measurements included the reactive strength index (RSI), which measures jump height per ground contact time, and the pro-agility test (PAT), a 20-meter sprint including two changes of direction. Results: Following the intervention, PAT scores significantly improved in RJT group compared with CON group (p < 0.01). Conclusions: This study showed that RJT positively affected the agility of preadolescent soccer players. RJT is an effective training method that is easy to sustain and can increase physical activity. Because the difficulty of the exercises can be adjusted by altering the types of jumps and the music, RJT is considered feasible for a wide range of age groups. Future research endeavours will require elucidating the improvement in various motor skills through RJT and determining the impact of long-term RJT interventions on injury incidence.
