Fatigue-induced performance reductions in jump, landing balance, and the agility of directional changes after landing can lead to decreased sports performance and an increased risk of injury. While pelvic belts are employed to enhance jumping and landing performance, their efficacy in reducing post-fatigue performance declines remains unclear. The purpose of this study was to investigate whether a compression garment with a pelvic belt (CG-PB) can suppress the deterioration of jumping and landing performance after fatigue. We hypothesized that wearing the CG-PB would contribute to reducing performance declines following fatigue. The experiment involved ten male participants and was conducted under two conditions: with and without the CG-PB (BELT and CON). Before and after the fatigue-inducing tasks, participants performed counter movement jumps (CMJ), single leg landings, and landing cuttings (LC), during which their movements and ground reaction forces were measured. While significant decreases in jump height during CMJ and lateral propulsion force during LC were observed post-fatigue in the CON (CMJ: p = 0.01, LC: p = 0.04), no significant differences were observed in the BELT before and after fatigue (CMJ: p = 0.99, LC: p = 0.13). Thus, the CGPB potentially relieves the reduction in vertical jump height and lateral propulsion force during LC after fatigue.
