Foam roller exercises are frequently used in training, especially during the warm-up phase. The aim of this study is to examine the acute effects of foam roller exercises performed only on the calf, quadriceps or gluteus maximus muscles on vertical jump performance and the time-course changes of these effects. In this study, 23 males participated voluntarily. The study was carried out using the crossover experimental design. In this study, the participants performed foam roller exercises on the calf, quadriceps, and gluteus maximus muscles on separate days. Foam roller exercises were performed in 3 sets and each set lasted 30 seconds. 30 seconds of rest was given to participants between the sets. Vertical jump performance was determined by measuring flight time using the Bosco Mat. The vertical jump test was performed before, immediately after (0.min), and at the 5th, 10th, 15th, 20th minutes after the foam roller exercises. The countermovement jump test protocol was performed to determine the vertical jump performance of the participants. Statistical analyzes were carried out to compare the jump heights of the participants by using the two-way analysis of variance in repeated measurements. As a result of the statistical analysis, no significant difference was found in the effects of group, time, and group×time (p>0.05). In this study, it was concluded that 3 sets of 30-second foam roller exercises applied to different muscle groups did not affect the vertical jump performance.
