The aim of this study was to investigate the effects of local quadriceps-hamstring (LFR) and Foam Roller (WBFR) performed to the whole body (calf, hamstring, quadriceps, adductor and latissimus dorsi) on quadriceps and hamstring 1 repeat maximal strength (1RM). The total of 14 volunteers who play soccer in the regional amateur league, participated to this study (age: 20.85 ± 3.97, Height: 1.78 ± .054 Kg: 64.55 ± 9.61, BMI: 20:21 ± 2.57). In the first stage, foam roller (FR) were performed to the H:Q muscle groups for 2x30 seconds to the athletes, and then 1RM strength measurements were performed until they were exhausted. After 3 days, FR was performed to the whole body for 2x30 seconds, and the athletes performed the 1RM strength test until they were exhausted. In the statistical analysis of the study, according to the conformity of the data to normal distribution, paired sample t-test and wilcoxon signed rank test were performed, and then the effect size was calculated. The results of the study showed that FR performed to the whole body produced more positive 1RM strength results compared to local FR performs (p <0.05). According to the results of this research, it is thought that the athletes will get more efficiency from the maximal strength results after FR performs they will perform to the whole body before 1RM strength measurements.
