Effect of Choline Supplementation on Rapid Weight Loss and Biochemical Variables Among Female Taekwondo and Judo Athletes

Taekwondo and judo competitions are divided into weight categories. Many athletes reduce their body mass a 
few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast body mass 
reduction, athletes use a number of nutritional strategies, including choline supplementation. The goal of this study 
was to identify the effects of choline supplementation on body mass reduction and leptin levels among female taekwondo 
and judo athletes. Twenty-two female athletes (15 taekwondo and 7 judo athletes) were selected from different weight 
categories and divided into two groups, according to weight. The players in the experimental group took choline tablets 
for one week before a competition. The results revealed significant differences between pre- and post-competition 
measurements of leptin, free plasma choline, urine choline and urine malondialdehyde levels; body mass was also 
reduced in the post-competition measurements. In conclusion, choline supplementation could rapidly reduce body mass 
without any side effects on biochemical levels or static strength. 
Key words: Choline supplementation, body mass reduction, biochemical variables, female athletes, combat sports.
