ABSTRACT
Purpose:
While take-off accuracy and approach run velocity are known determinants of long and triple jump performance, the interaction of these factors with step length adjustment (SLA) is not as clear.
Methods:
The study involved 39 male and 31 female national-level long and triple jumpers. The Optojump Next device was used to analyse jump attempts. Three groups were identified according to maximum variability of footfall placement (HVF - high, MVF - medium, LVF - Low) as well as three groups regarding the onset of step length adjustment (ESLA - early, MSLA - mid, LSLA - late).
Results:
Take-off accuracy in the LVF and MVF groups was greater compared with the HVF group among females. Among males, the LVF group made significantly (p < 0.05) fewer foul attempts than the HVF group. The ESLA group achieved significantly (p < 0.05) higher velocity during the last five steps of the approach run than the LSLA group in men.
Conclusions:
Coaches should implement exercises targeting SLA in long and triple jump training exercises to improve performance.
