The aim of this study is to investigate the effects of traditional strength and power interval training methods on the development of velocity parameters in the concentric phase of loaded-squat jump exercise and to determine which training method improves velocity parameters more. To achieve this goal, 30 male students who were studying at the School of Physical Education and Sports and did not regularly exercise participated voluntarily in this study. Participants were divided into three different groups using randomization: traditional strength training group, power interval training group, and control group. The participants performed a weighted squat jump exercise using external loads equivalent to 40% of their body weight in both pre-test and post-test measurements, and their mean velocity, mean propulsive velocity, and peak velocity values were obtained through an isoinertial velocity transducer. According to the analysis results, it was found that peak velocity significantly increased after traditional strength training. In addition, the power interval training method made a significant difference on the 1 RM pre-post test. The effect size of traditional strength training on peak velocity was determined as "small". In conclusion, it is thought that traditional strength training is a more prominent training method in improving movement velocity compared to power interval training.
