OBJECTIVE: This study aimed to identify changes in body mass and hydration status, alongside rapid weight loss (RWL) methods, in elite Para judo athletes with visual impairment.
METHODS: Using a cohort repeated-measures design, twelve elite Para judo athletes with visual impairment (6 males, 6 females; age: 33.1 ± 4.3 years) were monitored. Measurements occurred at three distinct time points: one week before the competition (T1), at the official weigh-in (T2), and on competition day (T3). Body weight was measured using a calibrated digital scale, and hydration status was evaluated through midstream urine samples analyzed for urine specific gravity (USG). Hypohydration was defined as a USG ≥ 1.020.
RESULTS: Athletes experienced a significant reduction in body weight, losing 3.89 ± 0.79 kg (5.2%) from T1 to the official weigh-in at T2. Following the weigh-in, athletes regained significant weight with a mean value of 3.44 ± 0.71 kg (4.8%) until the morning of the competition (T3). Hydration markers worsened alongside weight reduction; USG levels increased significantly from 1.023 ± 0.002 at T1 to 1.031 ± 0.002 at T2, indicating severe dehydration. Although USG values decreased significantly to 1.026 ± 0.001 by T3, they remained significantly higher than baseline levels. Notably, all of the athletes (100%) presented hypohydration one week before the competition, at the official weigh-in, and before the start of the competition.
CONCLUSION: Elite Para judo athletes with visual impairment utilize aggressive RWL strategies, resulting in significant weight fluctuations and severe dehydration at the time of weigh-in. Despite experiencing substantial body weight regain during the recovery period prior to the match, the athletes fail to adequately rehydrate, starting the competition in a continuous state of hypohydration.
