SLJ correlates more with squat than sprinting IMO.throwing athletes have very good SLJ because they are really strong..some bounding tests would correlate better with sprinting speed IMO..stephen francis said that no one at MVP is over 3.00m in the test..so asafa is under 3m in the SLJ.its probably a good test for team sport sport athlete where acceleration is important..but in 100m you need more than good explosive strength
