Erkek hentbolcularda antropometrik ve motorik özelliklerin sıçrayarak atış hızı üzerindeki yordayıcı rolü

Abstract

The aim of this study is to investigate the relationships between jump ball speed and various anthropometric and motoric characteristics in young male handball players. The study group consists of 14 elite level male handball players with a mean age of 18.85±0.36 years. Within the scope of anthropometric characteristics of the participants, height, body weight, body mass index (BMI), stroke length, bust length, hand length and hand width were measured. Motoric capacities were evaluated with variables such as leg strength, agility, reaction time, flexibility, grip strength and speed. Jump ball speed used as a performance indicator was determined accurately and reliably by radar speed measuring device. Pearson correlation and multiple linear regression analyses were used in the analysis of the data. As a result of correlation analyses, significant relationships were found between jump ball speed and stroke length (r = 0.674; p = 0.008), agility (r = 0.604; p = 0.022), reaction time (r = –0.672; p = 0.008), flexibility (r = 0.567; p = 0.034) and grip strength (r = 0.568; p = 0.034). According to the regression analysis results, significant predictors of jump ball speed were determined as stroke length (β = 0.492; p = 0.050), agility (β = –0.568; p = 0.021), reaction time (β = –0.438; p = 0.039) and flexibility (β = 0.567; p = 0.027). The regression model established explains 64.2% of the variance (R² = 0.642; F(4,9) = 8.982; p = 0.001). The findings reveal that not only technical skills but also anthropometric and motoric characteristics that form the basis of these skills are decisive in increasing the speed of the jump shot ball. Therefore, it is recommended that training programs be structured to develop motoric characteristics such as quickness, flexibility and reaction time.
