Résumé

Abstract Depending on the nature of their sports, athletes may be engaged in successive weight loss (WL) and regain, conducing to “weight cycling.” The aims of this paper were to systematically (and meta‐analytically when possible) analyze the post‐WL recovery of (i) body weight and (ii) fat mass; fat‐free mass; and performance and metabolic responses in weight cycling athletes (18–55 years old, body mass index < 30 kg.m −2 ). MEDLINE, Embase, and SPORTDiscus databases were explored. The quality and risk of bias of the 74 included studies were assessed using the quality assessment tool for quantitative studies. Thirty‐two studies were eligible for meta‐analyses. Whatever the type of sports or methods used to lose weight, post‐WL body weight does not seem affected compared with pre‐WL. While similar results are observed for fat‐free mass, strength sports athletes (also having longer WL and regain periods) do not seem to fully recover their initial fat mass (ES: −0.39, 95% CI: [−0.77; −0.00], p = 0.048, I 2 = 0.0%). Although the methods used by athletes to achieve WL might prevent them from a potential post‐WL fat overshooting, further studies are needed to better understand WL episodes consequences on athletes' performance as well as short‐ and long‐term physical, metabolic, and mental health.
