This research is a descriptive correlational study aimed at knowing the Contribution of Leg Explosive Power, Wrist Flexibility, Balance when doing lay-up shoots at Old School Makassar basketball club athletes. Based on the results of the study (1) The explosive power of the limbs obtained a correlation coefficient (r) of 0,946, while the RS (R Squer) value was 0,894 with a prob level. 0,000 is smaller than α 0,05. This means that there is a significant contribution of leg explosive power of 89,4% to the lay up shoot ability of the Makassar Old School Basketball Club Athletes. (2) Flexibility of the wrist obtained a correlation coefficient (r) of 0,919, while the value of RS (R Squer) was 0,844 with a prob level. 0,000 is smaller than α 0,05. This means that there is a significant contribution of wrist flexibility of 84,4% to the lay up shoot ability of the Makassar Old School Basketball club athletes, (3) Balance obtained by the correlation coefficient value (r) 0,827, while the RS value (R Squer) is 0,683 with level prob. 0,000 is smaller than α 0,05, this means that there is a significant balance contribution of 68,3% to the lay up shoot ability of Old School Makassar basketball club athletes.
