Abstract

The aim of the present investigation was to identifythe kinematic characteristics of dives that produce a greater peakflight height. Eight junior divers (13.25 ± 1.04 years) performedforward somersault dives at three different fulcrum settings offa one metre springboard. Selected variables were input to a stepwiseregression analysis to identify predictors of dive height. Significantpredictor variables were vertical velocity at touchdown, angle oflean at takeoff, vertical displacement at touchdown, ankle angleat touchdown, and external work. External work done during takeoff,although a significant predictor of dive height, was of relativelyminor influence when compared to the kinematic variables. This studyemphasises the importance of the hurdle flight in setting touchdownparameters that strongly determine take-off characteristics.
