Abstract:
The aim of this study was to investigate the methods adopted to reduce body mass (BM) in competitive athletes from the grappling (judo, jiu-jitsu) and striker (karate and taekwondo) combat sports’ athletes in the State of Minas Gerais Brazil. An exploratory methodology was employed through descriptive research, using a standardized questionnaire with objective questions self-administered to 580 athletes (25.0±3.7 yrs, 74.5±9.7 kg and 16.4±5.1% of body fat). Regardless of the sport, 60% of the athletes reported using a method of rapid weight loss (RWL) through increased energy expenditure. Strikers tend to begin reducing BM during adolescence. Furthermore, 50% of the samples used saunas and plastic clothing, and only 26.1% received advice from a nutritionist. We conclude that a high percentage of athletes use RWL methods. In addition, a high percentage of athletes use unapproved or prohibited methods, such as diuretics, saunas and plastic clothing. The age at which combat sports’ athletes reduce BM for the first time is also worry, especially among strikers.
