摘要：The aim of this study is to determine whether the anaerobic power and maximal strength are an important factor for velocity values during loaded-squat jump movement. For this purpose, 36 male students (age: 21,4 ± 1,57 years; height: 175,2 ± 5,91 cm; weight: 68,7 ± 7,12 kg) who are studying at school of physical education and sport at the Gumushane University and have active athlete license in different sport branches participated in the study voluntarily. In the study, loaded-squat jump (SJLoaded) movement was practiced by using an external load equaled to 40% of their body weights in order to determine velocity parameters of the participants. Also, in order to determine the maximal dynamic strength of the participants, one repetition maximal strength (1RM) in the full back squat (SQFull) movement and anaerobic power tests were done. For the analysis of data, Shapiro-Wilk normality test, descriptive statistics and Pearson Correlation analysis were used. According to the analysis results, there is a positive and statistically significant relationship between the absolute and relative 1RM strength values in the SQFull movement and mean relative anaerobic power values together with peak velocity values obtained in the concentric phase of SJLoaded movement of participants. Also, it was found that there is a positive and statistically significant relationship between 1RM squat strength and both absolute maximal anaerobic power and absolute mean anaerobic power values. There was no statistically significant relationship was found except for this. As a result, since there is a significant relationship between strength and velocity values in terms of absolute and relative, it can be asserted that as the strength increases, there will be an increase in peak velocity values during concentric phase and maximal strength training should be performed to provide an improvement in the movement velocity.
