Rapid weight loss in visually impaired judo athletes: Prevalence, magnitude, and methods

Abstract

The aim of this study was to determine the prevalence, magnitude, and methods of rapid weight loss (RWL) in visually impaired (VI) judo athletes, and compare these aspects between males and females. Thirty VI judo athletes (20 men and 10 women) completed a validated questionnaire to assess information about the magnitude and methods of RWL. Simple frequency was used to describe the influence and methods in all athletes and according to sex. Moreover, the t test was used to compare the variables between the sexes with the significance level set at p < .05. The main results showed that most VI judo athletes (67%) lost weight to compete. Most methods included gradual dieting (40%) and increased exercise volume (33%). The judo coach/ sensei was the person who most influenced the athletes in RWL (45%). There were no significant differences between the sexes regarding the RWL magnitude and methods used. As concluded, most VI judo athletes lost weight to compete, but the interval to reduce weight seemed slightly longer than it usually occurs in RWL. Gradual dieting and increased exercise volume were the most frequently used methods to lose weight, without any differences between males and females.
