Higher-protein diets do not hinder athletic perform in male fighters

Abstract

Background As Mixed Martial Arts grows in popularity, more athletes are participating in “weight cutting” to compete in weight classes that are below their regular weight. Current weight cutting techniques include dehydration, food restriction, diuretic use and self-induced vomiting to rapidly decrease weight. All of these can inhibit performance and negatively impact the health of an athlete. It was hypothesized that the use of a higher protein diet could be used to replace current weight cutting practices resulting in safer measures for the athlete without hindering athletic performance in male fighters. Design US Army soldiers (n=13, age=24±4yr, weight=75±13kg, body fat=14±7%) in the Combatives training program were recruited for this study. Prior to the start of the 6week training program participants were prescribed one of three diets: PRO (40% carbohydrate, 30% protein, 30% fat), CHO (65% carbohydrate, 15% protein, 20% fat) and control (no dietary restrictions). Pre-test and posttest assessments of vertical jump height, explosive leg power index (LPI), 600m shuttle and 1.5 mile run were completed during the first and last week of the 6-week program.
