This study investigated the prevalence, magnitude, and methods of rapid weight loss among male and female Taekwondo athletes from all competitive levels.

It is common for athletes in weight category sports to try to gain a theoretical advantage by competing in weight divisions that are lower than their day-to-day body mass (BM).

The aim of this study was to investigate the magnitude of rapid weight loss (RWL) of female and male young wrestlers at the Brazilian high-school games.

Most competitions in combat sports are divided into weight classes, theoretically allowing for fairer and more evenly contested disputes between athletes of similar body size, strength and agility.

Weight-sensitive sports are popular among elite and nonelite athletes. Rapid weight loss (RWL) practice has been an essential part of many of these sports for many decades.

Athletes competing in individual sports such as judo are categorized by weight. Before competitions, weight cutting is common.

Although some sports seem to present a higher risk of disordered eating compared to others, the effects are weak and heterogeneous. We make suggestions for the development of the research area, which has been severely hampered by the diagnostic tools that have been available for the study of men.
