[[alternative]]The Effects of 5 Weeks of Inspiratory Muscle Training on the Rowing Performance of Female Athletes.

[[abstract]]The inspiratory-muscle training is a new developed training method and it is beneficial for the respiratory-hindered patients. However, it is rarely used for the athletes to observe the potential to improve the performance. Purpose: This research was to investigate the effects of 5 weeks inspiratory muscle training on the rowing performance of female rowing athletes. Methods: There were 10 female competitive rowing athletes were recruited as the subjects. They were paired and randomly assigned to training group and control group. The training group athletes were trained for 5 weeks, 7 days per week, 2 times each day, 30 breaths each time with breathing mouth pieces (POWERbreathe,UK). After 5 weeks of training, the subjects were cross over and repeated the same process. The 5000 meters rowing trial performance and 6 minutes all-out (on rowing machine) and the rowing perceived scales were assessed before and after 5 weeks of training. The collecting data were analyzed by mixed-ANOVA. Results: 1.The 5000 meters after 5 weeks of inspiratory muscle training was significantly improved from 1319.96 seconds to 1286.01 seconds (p <.05)。2. The 6 min all-out （1513.5 m）after 5 weeks training was significantly better than the previous one (1479.9m) (p <.10)。3. The training subjects had better respiratory feeling during exercise.Conclusion: The Training Effect on Rowing Performance of 5000m and 6 min all-out can be improved with 5 weeks of Inspiratory muscle training.
