Pengaruh Latihan Ankle Weight Terhadap Peningkatan Kecepatan Lari Pemain Sepakbola Generasi Medan Krio

Abstract

Running speed is a crucial component in modern football performance, but a preliminary survey at Medan Krio Generation Football School showed that players' running speed is still relatively slow (average 17 seconds for 100-meter sprint). The use of ankle weight is believed to increase leg muscle strength and explosive power, which has the potential to increase running speed. Objective: This study aims to determine the effect of ankle weight training on increasing the running speed of Medan Krio Generation football players. Method: This study used a pre-experimental design with a one group pretest-posttest approach. The research sample was 20 U-15 football players from Medan Krio Generation Football School who were selected using the total samplingtechnique. The intervention in the form of ankle weight training was carried out for 4 weeks with a frequency of 3 times a week. Running speed measurements were carried out using a stopwatch at a distance of 100 meters. Data were analyzed using a paired sample T-test. Results The Wilcoxon test analysis showed a significance value (p < 0.001), indicating a significant difference between pretest and posttest results. Conclusion The use of ankle weights in a structured and consistent training program proved to significantly improve running speed.
