Abstract

INTRODUCTION: both Olympic weightlifting movements are usually considered to require the generation of maximum power in the moving bar. It is not clear, however, whether signs of a reduction in this power as the training period progresses are positive or negative in terms of final competition performance. The variables that influence the generation of this power may be affected by training, although the literature in this area is scant.

AIM: analyse how training influences maximum power generation and determine those kinematic variables that better predict performance.

METHOD: changes in the power behavior of the bar in the pull lift training exercise were analysed in four weightlifters (two men and two women) over a 53 week period leading up to an international competition. Data was distributed in three season moments and a one way ANOVA was used for analysis.

RESULTS: the relative height attained by the bar decreased (7% men, 8 % women) through the season (i.e., relative to the height of the weightlifter). Also mean (0.98-0.82 ms¹) and peak bar speed (2.37-1.92 ms¹) decreased in women.

CONCLUSIONS: the relative bar height attained became progressively lower as the competition date approached, even though the athletes were able to lift the same or even heavier loads than those used at the beginning of the training period, probably done to technical performance. This variable seems to be the best performance predictor of all kinematic variables.
