A cohort of 212 university athletes, active in sports, participated in the study. Hop tests, comprising four distinct procedures, were administered to evaluate lower extremity strength. The hop tests demonstrated high reliability, with reliability coefficients ranging from 0.704 to 0.990. Examination of asymmetry indices revealed mean values of 101.07%, indicative of symmetrical limb function among participants. Gender-based differences were notable in hop test results, particularly in the crossover hop test, which showed significant asymmetry (p</p></abstract>

Çalışmaya toplamda 212 sporcu öprenci katılım gösterdi. Alt ekstremite kuvvetini değerlendirmek için dört farklı prosedürden oluşan hop testleri uygulandı. Analiz sonuçlarında hop testin Türk sporcu öğrenci örnekleminde güvenirlik düzeyleri 0,704-0,990 arasında olduğu ve yüksek düzeyde güvenirliğe sahip olduğu belirlendi. Sporcu öğrencilerin asimetri indekslerine bakıldığında ortalamaların 101,07% olduğu ve bu grubun normal uzuv simetrisine sahip olduğu belirlendi. Sporcu öğrencilerin cinsiyetleri açısından hop test değerlerinde farklılıkların olduğu, asimetri indeksi açısından ise sadece çapraz atlamada fark oluştuğu görüldü (p</p></trans-abstract>
