Abstract

We evaluated the effects of a 7-day rapid weight loss (RWL) intervention on body composition and biomarkers of creatine metabolism in eight elite judokas during a pre-competition period. RWL induced a significant drop in weight (81.7±10.7 kg at baseline vs. 76.8 ± 10.3 kg at follow-up; p<.001), fat mass (12.6±5.6 kg vs. 9.2±4.0 kg; p=.003) and fat-free mass (69.1±7.3 kg vs. 67.6±7.7 kg; p=.05), accompanied by an increase in serum creatinine levels at follow-up (104.0±10.5 µmol/L vs. 114.9±10.2 µmol/L; p=.009). An acute restriction of food and fluid intake appears to negatively affect fat-free mass and indices of kidney function in judokas.

快速减重对柔道运动员体成分和肌酸代谢循环指标的影响

我们评估了7天快速减肥(RWL)干预对8名优秀柔道运动员赛前身体成分和肌酸代谢生物标志物的影响。RWL诱导体重显著下降(基线时为81.7±10.7 kg，随访时为76.8±10.3 kg;P < 0.001)，脂肪质量(12.6±5.6 kg vs. 9.2±4.0 kg;P = 0.003)和脱脂质量(69.1±7.3 kg vs.67.6±7.7 kg;p= 0.05)，随访时血清肌酐水平升高(104.0±10.5µmol/L vs.114.9±10.2µmol/L;p = .009)。急性限制食物和液体摄入似乎会对无脂质量和肾功能指标产生负面影响。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
