Prevalence and Magnitude Weight Loss Among Collegiate Wrestlers

Jagim, AR, Dobbs, WC, Horswill, CA, Twohey, E, Fields, JB, and Jones, MT. Prevalence and magnitude weight loss among collegiate wrestlers. J Strength Cond Res 40(1): 90-97, 2026-The purpose of this study was to examine the percentage of wrestlers who compete in their minimal weight class (MWC), and the magnitude of weight loss. Data from the 2023-2024 collegiate season were retrospectively analyzed resulting in a sample of 9,638 collegiate male wrestlers from the National Association of Intercollegiate Athletics ( n = 1,904) and all 3 divisions of the National Collegiate Athletics Association ( n = 7,734). All wrestlers completed skinfold assessments for weight certification at the start of the competition season. The lowest recorded weight class (LRW) achieved by each wrestler during the season was also recorded and used to determine magnitude of weight loss. Out of the 4,605 (53.2%) of wrestlers who competed in their MWC, their average amount of weight loss was significantly higher than those who did not compete in their MWC (3.9 ± 2.5 vs. 3.2 ± 2.9 kg.; p < 0.001), yet they had an initial lower body fat percentage (12.7 ± 2.9 vs. 17.5 ± 4.8%; p < 0.001). At the time of weight certification, wrestlers weighed 8.1 ± 4.5 (95% confidence interval (CI): 8.0-8.2; effect size (ES) = 1.8) kg more than their minimal wrestling weight. The LRW was 3.6 ± 2.9 (95% CI: 3.6-3.7; ES = 1.2) kg lower than their weight at the time of weight certification. Given that slightly more than half of the male wrestlers competed in their MWC, coaches and sports practitioners should recognize that not all athletes follow the traditional assumption of cutting to the lowest possible weight class. Importantly, those who did achieve their MWC had lower initial body fat percentages, limiting the amount of weight they could safely lose. This underscores the need for individualized weight management strategies that consider body composition and health implications.
