Methods: Ten male athletes (age, 20 ± 1.25 yrs; height, 175.1 ± 4.12 cm; weight, 63.8 ± 4.42 kg) were voluntarily recruited in this repeated measures and crossover designed study. All participants were requested to perform three different experimental treatments, including inspiratory muscle warm-up (IMW), placebo (PLA) and control (CON). The control trial was without IM warm-up while the PLA and IMW were with IM warm-up by performing two sets of 30 breaths at 15% and 40% maximum inspiratory mouth pressure (PImax), respectively. After treatment, participants ran on treadmill with 100% vVO2max until exhaustion. The running distance, blood lactate, ratings of perceived exertion (RPE), and rating of perceived breathlessness (RPB), were measured during the experiments. Results: No significant differences were found on the blood lactate, RPE and RPB three treatments. The running distance in IMW were significantly higher than in CON and PLA (CON vs. PLA vs. IMW，1532 ± 359.15 vs. 1685.2 ± 456.45 vs. 1930.40 ± 544.56 m，F＝10.552，p＜.05). Conclusion: These results indicate that the IMW might improve endurance performance in athletes.
