- W2953641375 abstract "The influence of maximal sprint exercise in hypoxia on muscle glycogen content muscle has not been directly evaluated. PURPOSE: The purpose of the present study was to determine the effect of a single bout of maximal sprint exercise in hypoxia on muscle glycogen content among competitive athletes. METHODS: Ten sprinters (height; 176.9 ± 1.9 cm, body weight; 66.9 ± 2.0 kg, BMI; 21.4 ± 0.5 kg/m2, athletic career, 10.3 ± 2.9 years) performed two exercise trials under either hypoxic [HYP, fraction of inspired oxygen (FiO2): 14.5%, a simulated altitude of 3,000m] or normoxic (NOR, FiO2: 20.9%) conditions with a randomized, a single-blind and crossover design. The exercise in each trial consisted of three sets of 30-s maximal sprint. Muscle glycogen content was measured using carbon magnetic resonance spectroscopy (13C-MRS) in the vastus lateralis and vastus intermedius muscles before and after the exercise. Moreover, time-course changes in power output, percutaneous oxygen saturation (SpO2), blood lactate, metabolic responses and muscle oxygenation were evaluated. RESULTS: The average SpO2 value was significantly lower in the HYP trial (91.0 ± 0.3%) than in the NOR trial [95.9 ± 0.3%, P < 0.01, effect size (ES) = 5.08]. Mean power output did not differ significantly between the two trials (P = 0.80, ES = 0.01). There was a significant main effect for time (P < 0.01, ES = 0.97) for blood lactate concentration, but no significant difference between the two trials was observed (P = 0.31, ES = 0.12). Change in muscle glycogen content showed significant interaction (P = 0.03, ES = 0.40) and main effect for time (P < 0.01, ES = 0.89). Relative change in muscle glycogen content between before and after the exercise was significantly greater in the HYP trial (-43.5 ± 0.4 %) than in the NOR trial (-34.0 ± 0.3 %, P < 0.01, ES = 0.83). CONCLUSION: Maximal sprint exercise in hypoxia caused further decrement of muscle glycogen content compared with the same exercise under normoxia." @default.
