Benefits of LLTH in systematic hypoxia models to improve sea-level performance are more evident in anaerobic efforts. Literature has mentioned 4 training types (Continuous-Hypoxic Training, Interval-Hypoxic Training, Repeated-Sprint Training in Hypoxia and Resistance- Training in Hypoxia) in LLTH, but a pure plyometric training in hypoxia wasn't seen yet. Therefore, it was aimed to investigate the effects of plyometric training in hypoxia on Wingate test variables. 23 male volunteers from physical education students (age=20.39±2.02) who did not perform resistance and plyometric exercises in the last 6 months participated in the study. They were divided into the groups of Plyometric Hypoxia(PH)(n=8), Plyometric Normoxia(PN)(n=7) and Control(n=8). While PH performed drop jump, split-squat jump, countermovement jump and squat jump exercises in normobaric hypoxic-environment (3.536m) with a face mask attached to a hypoxic generator for 3 days/week throughout 8 weeks, PN executed the same program in normoxic-environment without a mask. While mean oxygen saturation of PH group varied between 82.8 and 84.7%, that of PN group was between 95.3 and 96% during the exercises. Control- group participants continued just their own physical activity. While Wingate results showed no significant difference between the groups, a significant increase of 60.53W(7.72%)(p=.02,r=-.60) in PH and 46.14W (6.09%)(p=.03,r=-.59) in PN were found in peak power in intragroup-comparison. Relative peak power significantly increased by 0.89W/kg (7.89%)(p=.05,r=-.49) in PH, and by 0.81W/kg (7.05%) (p=.02,r=-.63) in PN. An insignificant increase of 0.36W/kg (4.41%)(p=.07,r=-.46) in PH and a significant increase of 0.79W/kg (10.06%) (p=.02,r=-.63) in PN were observed in relative average power, whereas there was no significant change in average power in all three groups. Although there is an approach suggesting similar training programs produce higher performance efficiency by providing more physiological and muscular adaptations when performed in hypoxia, this study results showed that plyometric training in hypoxia doesn't provide greater improvement in Wingate test variables versus normoxia.
