This study aims to determine the effect of six-week plyometric training on the reactive strength index (RSI) and anaerobic capacity in U18 male football players. In the study, a pre-test post-test control group design, one of the experimental models of the quantitative research method, was used. A total of 18 male football players who voluntarily participated in the study were randomly assigned to the experimental group (n=9) and the control group (n=9). While the football players in the experimental group followed a plyometric training program three times a week for six weeks in addition to their regular football training, the football players in the control group only continued their regular football training during this period. Prior to the training program and at the end of the six-week period, the participants underwent assessments including the Reactive Strength Index (RSI) and the Wingate Anaerobic Power Test (WAnT). The normality of the data was determined using the Shapiro-Wilk test. For the analysis of normally distributed data, the Independent Sample T-Test was used for independent groups, while the Paired Sample T-Test was employed for dependent groups. According to the findings of the study, a significant difference in favor of the post-test was observed in the Reactive Strength Index (RSI) (t = -2.353; p = 0.046) and peak power (PP) (t = -3.418; p = 0.009) parameters of the experimental group football players. However, no significant difference was found in the mean power (MP) and fatigue index (FI) parameters. In conclusion, it was determined that the six-week plyometric training program applied to U18 male football players had positive effects on RSI and PP values.

U18 Erkek Futbolcularda Altı Haftalık Pliometrik Antrenmanların Reaktif Kuvvet İndeksi ve Anaerobik Kapasiteye Etkisi

Öz

Bu çalışamanın amacı, U18 erkek futbolculara uygulanan altı haftalık pliometrik antrnmanların reaktif kuvvet indeksi (RSI) ve anaerobik kapasiteye etkisini belirlemektir. Araştırmada nicel araştırma yöntemi deneysel modellerinden ön test-son test kontrol gruplu desen kullanıldı. Araştırmaya gönüllü olarak katılan 18 erkek futbolcu seçkisiz olarak deney grubu (n=9) ve kontrol grubuna (n=9) ayrıldı. Deney grubundaki futbolculara düzenli futbol antrenmanına ek olarak altı hafta boyunca haftada 3 gün pliometrik antrenman programı uygulanırken kontrol grubundaki futbolculara bu sürede yalnızca düzenli futbol antrenmanı uygulandı. Araştırmaya katılan futbolculara antrenmanlar öncesi ve altı haftalık antrenmanlar sonunda RSI ve Wingate anerobik güç testi (WAnT) uygulandı. Verilerin normallik düzeyi Shapiro-Wilk testi ile belirlendi. Normal dağılım gösteren verilerin analizinde bağımsız gruplar için Independent Sample T Testi ve bağımlı gruplar için Paired Sample T Testi kullanıldı. Araştırmadan elde edilen bulgulara göre deney grubundaki futbolcuların RSI (t = -2,353 ; p = 0.046) ve zirve güç (PP) (t = -3,418 ; p = 0.009) parametrelerinde son testler lehine anlamlı bir fark tespit edillirken, ortalama güç (MP) ve yorgunluk indeksi (FI) paremetrelerinde anlamlı bir farklılık bulunmamıştır. Sonuç olarak, U18 erkek futbolculara uygulanan altı haftalık pliometrik antrenmanların RSI ve PP değerlerinde olumlu etkiler sağladığı belirlenmiştir.
