Abstract

Alt Yapı Voleybol ve Basketbol Sporcularında Reaktif Güç Profillemesi: RSI Temelli Bir Segmentasyon Modeli

ÖZET
Bu çalışmanın temel amacı, altyapıda aktif olarak voleybol ve basketbol branşlarında antrenman yapan genç sporcuların reaktif güç kapasitelerini RSI (Reactive Strength Index), CMJ (Countermovement Jump) ve SJ (Squat Jump) testlerinden elde edilen veriler aracılığıyla değerlendirmek; bu veriler ışığında sporcuları performans profillerine göre segmentasyon modeli ile gruplandırmak ve ortaya çıkan gruplar arasında çeviklik, sıçrama ve hız gibi fiziksel performans değişkenleri açısından anlamlı fark olup olmadığını belirlemektir. Çalışmada, RSI düzeyi yüksek sporcuların patlayıcı kuvvet, sprint ve çeviklik testlerinde daha yüksek performans sergileyip sergilemediği incelenecek; CMJ ve SJ testleri arasındaki fark yüzdesi değerlendirilerek stretch–shortening cycle (SSC) kullanım verimliliği yorumlanacak ve RSI ile bu fark arasındaki ilişki analiz edilecektir. Saha ölçümleri tek günde yapılacak ve veriler çok değişkenli istatistiksel yöntemler ile değerlendirilecektir.

REACTIVE POWER PROFILING IN YOUTH VOLLEYBALL AND BASKETBALL ATHLETES: AN RSI-BASED SEGMENTATION MODEL

Year 2025, Volume: 6 Issue: 3, 238 - 246, 22.12.2025

Abstract

The primary objective of this study is to assess the reactive power capacity of young athletes actively training in volleyball and basketball at the youth level using data obtained from the RSI (Reactive Strength Index), CMJ (Countermovement Jump), and SJ (Squat Jump) tests. Based on this data, the athletes will be grouped according to their performance profiles using a segmentation model and determined whether there are significant differences between the resulting groups in terms of physical performance variables such as agility, jumping, and speed. This study will examine whether athletes with higher RSI levels exhibit higher performance in explosive strength, sprint, and agility tests. The percentage difference between the CMJ and SJ tests will be evaluated to interpret the efficiency of stretch-shortening cycle (SSC) utilization and analyze the relationship between this difference and RSI. Field measurements will be conducted on a single day, and the data will be analyzed using multivariate statistical methods.
