| Popis: | [Purpose] The present study aimed at examining changes in aerobic energy metabolism and performance in cycling athletes after 2 weeks of intermittent training in a multistep hypobaric hypoxia environment. [Subjects and Methods] We also aimed at using the findings to propose an efficient training program in hypobaric hypoxia for endurance athletes with disabilities. The study participants were three cycling athletes with physical disabilities from the Korean national team (A, B, and C athletes). They underwent complex (repetition, interval, and continued) training with a roller-type cycle in a multistep hypobaric hypoxia environment (simulated altitude, 4,000 m above sea level). The training was conducted in twelve 60-min sessions for 2 weeks and it was based on the ventilatory threshold intensity, measured in an exercise stress test, conducted prior to training, at constant temperature (23 °C ± 2 °C) and humidity conditions (50% ± 5%). [Results] B and C athletes showed no noticeable changes in relative VO2max and HRmax values after training. A, B, and C athletes all showed increases in all-out time, 2′09″ (13.1%), 2′43″ (18.7%), and 1′22″ (7.4%), respectively after training. Although the relative VO2max and HRmax values were not improved, submaximal exercise performance ability was improved. [Conclusion] Therefore, 2 weeks of intermittent training in a hypobaric hypoxia environment positively affected aerobic energy metabolism and performance. |
