We aimed to evaluate the effects of a 2-week exercise training program in hypobaric hypoxic conditions on exercise performance and immune function in Korean national cycling athletes with disabilities. Six Korean national cycling athletes with disabilities participated in exercise training consisting of continuous aerobic exercise and anaerobic interval exercise in hypobaric hypoxic conditions. The exercise training frequency was 60 min (5 days per week for 2 weeks). Before and after the exercise training, exercise performance and immune function were measured in all athletes. Regarding the exercise performance parameters, the 3-km time trial significantly decreased and blood lactate levels after the 3-km time trial test significantly increased by exercise training in hypobaric hypoxic conditions. Regarding the oxygen-transporting capacity, significant differences were not observed. Regarding immune function, the number of leukocytes and natural killer cells significantly decreased and that of eosinophils, B cells, and T cells significantly increased. These results indicated that our 2-week hypoxic training showed the potential to improve exercise performance in Korean national disabled athletes. However, the effects of our hypoxic training method on immune function remained unclear.
我们旨在评估在低气压缺氧条件下进行为期 2 周的运动训练计划对韩国残疾国家自行车运动员运动表现和免疫功能的影响。六名韩国残疾国家自行车运动员在低气压缺氧条件下进行了连续有氧运动和无氧间歇运动的运动训练。运动训练频率为 60 分钟（每周 5 天，共 2 周）。在运动训练前后，所有运动员都测量了运动表现和免疫功能。关于运动表现参数，在低气压缺氧条件下进行的 3 公里计时赛中，3 公里计时赛的时间明显缩短，3 公里计时赛后的血乳酸水平明显升高。关于氧运输能力，没有观察到显著差异。关于免疫功能，白细胞和自然杀伤细胞的数量明显减少，嗜酸性粒细胞、B 细胞和 T 细胞的数量明显增加。这些结果表明，我们为期 2 周的低氧训练有可能提高韩国残疾运动员的运动表现。然而，我们的低氧训练方法对免疫功能的影响仍不清楚。
