Investigating of the relationship between sprint and jump performance with power parameters during propulsive phase of full back squat exercise

The basic purpose of this study was to investigate of the relationships with sprint and jump performance of power parameters during propulsive phase of full back squat exercise and to determine which variable was associated with which loading loading. For this purpose, thirty-two men amateur athletes (age: 20.4 ± 1.98 years; height: 179.3 ± 7.23 cm; weight: 73.5 ± 9.85 kg) who actively involved in sports and have a basic level of force participated in voluntarily to this study. In the study, one repetition maximum (1RM) full back squat (SQ) strength test, vertical jump test, 5 meters and 30 meters sprint test were applied. The descriptive statistics and pearson correlation analysis was used for statistical evaluation of datas. According to statistical analysis results; It was concluded that there are mean level, negative and statistically a significant relationship between mean propulsive power (MPP) values (r = - ,607, p < 0.05) obtained at 70 % of 1RM load values and mean power (MP) values (r = - ,409; r = - ,454; p < 0.05, respectively) and peak power (PP) values (r = - ,445; r = - ,365, p < 0.05, respectively) obtained in the propulsive phase of full back squat exercise performed at 40 % and 70 % of 1RM load value with 5 meters sprint times. It was concluded that there are mean level, negative and statistically a significant relationship between PP values (r = - ,400; r = - ,355, p < 0.05, respectively) obtained at 40 % and 60 % of 1RM load values OG (r= - ,375; r = - ,394, p< 0.05) respectively) values obtained in the propulsive phase of full back squat exercise performed at 40 % and 70 % of 1RM load value with 30 meters sprint times. It was obtained that there are no statistically a significant relationship between power parameters during propulsive phases of full back squat exercise performed in different loads of 1RM and vertical jumping distance (p > 0.05).
