Abstract (2. Language): 
The purpose of this study was to investigate if the grip strength could be used to predict upper body strength of college football players through comparing dominant grip strength and upper body strength of college football players. Forty-one Division II National Collegiate Athletic Association football players (24 defensive players and 17 offensive players) participated in the present study. A grip strength dynamometer was used to measure grip strength of football players and the one-repetition maximum (1RM) bench press was used to measure participants’ upper body strength. Each player had undergone a minimum of eight weeks of heavy resistance training during the winter off-season conditioning program prior to measurement. None of the participants had a serious pre-existing injury that could hinder their performance throughout the study, and participants in the study had the ability to understand and perform bench press and grip strength tests. The Pearson product-moment coefficients of correlation and a simple regression were computed to determinerelationship between 1RM bench press and grip strength. One-way analyses of variance (ANOVA) were conducted to test the differences in upper body and grip strength among offensive and defensive college football players and their player positions by using their relative strength. Notably, strength scores were divided by body weights to express bench press and grip strength relative to weight. The results of this study showed that grip strength test did not predict the upper body strength of college football players when we used the 1RM bench press strength test as a standard test to measure upper body strength of players (β = .248, p = .118).
Abstract (Original Language): 
Bu araştırmanın amacı, Amerikan kolej futbol oyuncularının dominant el kavrama kuvvetleri ile üst beden kuvvetlerini karşılaştırarak, el kavrama kuvvetlerinin üst beden kuvvetlerini tahmin etmede kullanılıp kullanılmayacağını incelemektir. Kırk bir II. Küme Amerikan Milli Kolej Atletik Birliği futbol oyuncuları (24 savunma ve 17 hücum oyuncusu) bu çalışmaya katılmıştır. Katılımcıların kavrama kuvvetlerini belirleyebilmek için bir el kavrama dinamometresinden ve üst beden kuvvetinin tespiti için bir tekrarlı maksimum bench press testinden (1RM) yararlanılmıştır. Testlerin uygulama aşamasında katılımcıların herhangi bir ciddi sağlık sorunları ve sakatlanma problemleri olmamıştır. El kavrama kuvveti ve 1RM bench press arasındaki ilişkinin belirlenmesinde Pearson Product Correlation ve Simple Regression analizleri kullanılmış, oyuncuların pozisyonlarına göre kuvvetlerinde farklılık olup olmadığı ANOVA ile belirlenmiştir. İstatistik analizlerinde futbol oyuncularının kaldırdıkları ağırlıklar kendi beden ağırlıklarına bölünmek suretiyle elde edilen rölatif kuvvet sonuçları kullanılmıştır. Bu araştırmanın sonucu, el kavrama kuvvetinin, 1RM bench press kuvvet testi kullanılarak elde edilen üst beden kuvvetini tahmin etmede yeterli olmadığını göstermiştir (β = .248, p = .118).
