The effects of 12 weeks of high-intensity interval rope skipping training on speed qualities in male soccer players: a randomized controlled trial

Abstract Objectives: This study was to investigate the effects of high-intensity interval jump rope training on the speed qualities of soccer players. Design: Randomized controlled trial Methods: T Methods: Twenty-five elite soccer players were randomly assigned to an experimental group (N=13) performing high-intensity interval jump rope training and a control group (N=12) undergoing traditional training for 12 weeks. Both groups trained two times per week. Speed qualities were assessed using 30-meter sprint, Optojump rapid frequency and visual reaction tests, T-run test, and standing long jump. Data were analyzed using Two-factor repeated measures ANOVA.） Results: High-intensity interval rope skipping training could improve sprint speed (P=0.000***), movement speed (P=0.000**), visual reaction speed (P= 0.000**), change of direction speed (P= 0.000**), and explosive speed (P= 0.000**). Further, compared to traditional training methods, high-intensity interval rope skipping training was more effective in sprint speed(P=0.033**) and visual reaction speed(P= 0.010**). Conclusions: High-intensity interval rope skipping training can improve the speed quality of soccer players, especially in sprint speed and visual reaction speed.
