Weight cycling in adolescent Taekwondo athletes.
Kazemi M, Rahman A, De Ciantis M.
BACKGROUND: Weight reduction cycles are used by weight classed athletes in Taekwondo to make a weight category. Tension, dizziness, headaches, and confusion have been associated with rapid weight loss (RWL). There is a lack of research in weight cycling and its benefits among Taekwondo athletes.
PURPOSE: To investigate the rate of weight cycling in Junior Taekwondo athletes and its effect on performance.
METHODS: Athletes were weighed prior to competition, then again before their first match. Body mass difference in relation to winning was compared.
RESULTS: A significant increase from weigh-in to pre-match measurements was consistently found in both genders with no significant difference between them. Winners had a mean body mass gain (1.02 kg) which was non-significantly less than the non-winners (1.09 kg).
CONCLUSIONS: RWL practices do not define which athlete will perform better. Negative effects of weight cycling coupled with RWL has unclear performance benefits which indicates a need for further research.
