Making Weight in Combat Sports


Learning Objectives

  • To describe the rationale for weight loss in athletes in combat sports

  • To identify undesirable (unregulated) methods of reducing weight by weigh-class athletes

  • To recommend appropriate methods (regulated) for making weight

  • To describe the adverse effects of making weight on performance, acute physiology, and chronic nutritional status

2.1 Introduction

Unlike most other sports, combat sports match competitors based on size. The purpose of matching, which relies on body mass, is to create equity between opponents and reduce injury risk because of discrepancies in physical strength and mass. Utilizing weight classes also allows a broad range of specific-sized individuals to participate (Tables 22.1 and 2.2). This is seldom the case with team sports and non-combat individual sports in which athletes of greater mass are drawn to the sport. By pairing opponents by mass, skills, strategy, relative strength, and conditioning are emphasized as factors that produce success...
