R—right side; L—left side; Baseline—the first measurement; After—measurement after application of self-myofascial release technique (in Group 1) and after 15 min without any intervention (in Group 2); SD—standard deviation; p ^a—p value between first and second measurement within each group; p ^b—p value between study groups. Values are expressed as Mean ± SD; bold—statistically significant.
