Abstract：
Combat sports athletes seeking a competitive edge often engage in weight management practices to become larger than their opponents, which ultimately includes periods of gradual weight loss, rapid weight loss, and weight regain. This pattern of weight loss and regain is known as weight cycling and often includes periods of low energy availability, making combat sports athletes susceptible to metabolic dysfunction. This narrative review represents an effort to explore the metabolic perturbations associated with weight cycling and outline the short-, medium-, and long-term effects on metabolic flexibility, function, and health. The short-term effects of rapid weight loss, such as a reduced metabolic rate and alterations to insulin and leptin levels, may prelude the more pronounced metabolic disturbances that occur during weight regain, such as insulin resistance. Although definitive support is not currently available, this cycle of weight loss and regain and associated metabolic changes may contribute to metabolic syndrome or other metabolic dysfunctions over time.
摘要：
寻求竞争优势的战斗运动运动员经常从事体重管理实践，使其变得比对手大，最终包括逐渐减轻体重的时期，快速减肥，和体重恢复。这种体重减轻和恢复的模式被称为体重循环，通常包括能量利用率低的时期，使格斗运动运动员容易发生代谢功能障碍。这篇叙述性综述代表了探索与体重循环相关的代谢扰动的努力，并概述了短，medium-,以及对代谢灵活性的长期影响，函数,和健康。快速减肥的短期影响，如降低的代谢率和改变胰岛素和瘦素水平，可能是体重恢复过程中发生的更明显的代谢紊乱的前奏，如胰岛素抵抗。尽管目前尚无明确的支持，随着时间的推移,这种体重减轻和恢复以及相关代谢变化的循环可能导致代谢综合征或其他代谢功能障碍.
