Abstract
Soccer is a globally popular Olympic sport. The aim of this study was to investigate the relationship between kicking velocity and leg power among soccer players across different playing positions. A total of thirty (30) male soccer players, classified into defenders, midfielders, and forwards participated in the study. Leg power was assessed using the vertical jump test, while kicking velocity was measured using a radar gun during standardized kicking trials. The mean leg power of forward groups was 57.7 kg-m/sec and ball velocity is 98.3 km/h; mean leg power of midfielder groups is 55.1 kg-m/sec and ball velocity is 92.2 km/h; mean leg power of defender groups is 56.5 kg-m/sec and ball velocity is 97.4 km/h. The finding revealed a significant positive correlation between leg power and kicking velocity (p < .05), with forwards and defenders exhibiting higher values compared to midfielders. These findings highlight the role of leg power in contributing to effective kicking performance and suggest that positional demands in soccer influence the development of these physical attributes. Understanding these relationships can inform position-specific training programs to enhance player performance.
