The effect of Hopz exercises on the explosive power of leg muscles and the accuracy of heading goals in young soccer players

Abstract

The importance of the research lies in studying the effect of hopz training on developing the explosive ability of the leg muscles, and its reflection on improving the skill of heading the ball among young football players, which contributes to raising their physical and technical efficiency in line with the requirements of the modern game. The aim of the research is to: identify the effect of hopz training on the explosive ability of the leg muscles and the accuracy of heading the ball among young football players. The researchers used the experimental method with a single experimental group design accompanied by pre- and post-tests. The research community was represented by the players of the Al-Hay district clubs participating in the Wasit Governorate League for the sports season (2024-2025), numbering (72) players, aged between (17-19) years. As for the basic research sample, it was chosen randomly, and it was represented by the players of Al-Hay Sports Club, as their number amounted to (12) players out of (24) players, after excluding the goalkeepers and four injured and physically unprepared players, and choosing (6) other players randomly for the purpose of conducting the two experiments. The two surveys, which constituted a sample of (16.66%) of the total research population, concluded that the use of Hopz training contributed effectively to developing the explosive capacity of the leg muscles in young soccer players.
