r = PearsonĀ“s correlation coefficient; rt = KendallĀ“s tau correlation coefficient = 1RM BS = one-repetition maximum for the back squat; 1RM SCR = one-repetition maximum for the standing calf raise; SJ = squat jump; RSI 24 = reactive strength index from the 24 cm falling height; RSI 32 = reactive strength index from the 32 cm falling height; RSI 40 = reactive strength index from the 40 cm falling height; 20-m LS = 20-meter Linear Sprint; COD = change of direction sprint; * = level of significance (p < 0.05)
