Methods Twenty elite athletes (age: 20.6 ± 2.2 years; body mass: 72.3 ± 14.4 kg; height: 1.73 ± 0.09 m) were assessed during a 10-day period leading up to competition. Body mass, heart rate variability (HRV) at rest, cognitive performance, and technical-tactical performance were examined. Athletes were categorized into moderate (MWLG, n = 9) and high (HWLG, n = 11) weight-loss groups. Statistical analyses included repeated measures ANOVA and correlation tests. Results Both groups showed significant body mass reduction (MWLG: mean: 3.0 ± 2.0%; HWLG: mean: 6.8 ± 1.5%), with moderate to strong correlations between body mass reduction and increased response times on Flanker task (r = 0.52–0.61, p < 0.05). HRV indices remained stable, reflecting athletes’ physiological resilience across the pre-competition period. Importantly, no significant differences were observed between groups in technical-tactical performance, self-control and inhibitory control. Conclusion WL was moderately associated with delayed response times on an inhibitory control task, indicating a change in cognitive strategy. These findings emphasize the need for integrated strategies combining weight management, recovery protocols, and cognitive training, as the observed associations between WL and cognitive response times may influence decision-making processes without directly impairing technical-tactical performance. 2026-01-09T11:52:41Z 2026-01-09T11:52:41Z 2025-10-30 journal article Conceição-Santos, D.
