Influence of skill training variations on technical and physical performance in youth soccer

Abstract

This study examined how varied skill repetition affected the performance of 14–16-year-old male soccer players. Thirty-seven players were randomly assigned to a low repetition skill training group (LRSTG, n = 13), a high repetition skill training group (HRSTG, n = 12), or a control group (CG, n = 12). Over six weeks, the LRSTG and HRSTG supplemented their regular team training with structured drills in passing, shooting, and dribbling (DR), while the CG continued their usual football activities. Performance was assessed via anthropometric measurements, the Y Balance Test (YBT), 10 and 30 m sprint tests, vertical jump (VJ), the Little & Williams Zigzag Agility Test (LWZ), and the Mor & Christian Soccer Ability Test. A double-blind design was used. Both the LRSTG and HRSTG demonstrated statistically significant improvements (p < 0.05) in accurate passing (AP) and accurate shooting (AS), with DR performance improving only in the LRSTG. Compared to the CG, who showed no significant changes in these technical skills, both experimental groups exhibited significantly better AS, and LRSTG demonstrated higher DR. Additionally, the experimental groups showed significant gains in 10m sprint and agility. However, no significant changes were found in VJ, YBT, or 30-m sprint across any group. These findings suggest that adjusting repetition volume in skill training can improve both technical and physical performance, challenging previous claims about the limited value of repetitive drills. The results have implications for coaches planning more effective training programs.
