Purpose: The purpose of this study is to confer the intervene of 5-week inspiratory muscle training to see if it can boost the interval anaerobic sport ability and foot work performance. Method: to select 10 collegiate male badminton players, using the breathing mouth pieces (POWERbreathe, UK). They were paired and randomly assigned to experiment group (EPG, N=5) and control group (CG, N=5). The former proceeds 5 weeks training: 7 days a week, twice a day, 30 times once by using the POWERbreathe. After 5 weeks, the latter is to take turns to performance the same training program. Modified Borg Scale of Rating Perceived Exertion (RPE) was implied to estimate effort and exertion of the subjects. Tow way ANOVA was used to compare the differences. Result: 5 weeks of inspiratory muscle training found the 2 groups have no significant difference in interval anaerobic ability. While on the foot work performance, considering the trainee’s different ability level in the beginning, the grade of each stage is referred to a progress percentage. By analyzing datum to show the progress rate of inspiratory muscle training in the foot work performance on each stage has remarkably better than control group in the same period. While on the respiratory RPE, the training effectively make less difficult of the interval anaerobic sport ability; However, the foot work performance has little progress to have no significant difference. Conclusion: The intervene of a 5-week inspiratory muscle training to collegiate male badminton players can effectively enhance the foot work performance, and make less difficult of the interval anaerobic sport ability and foot work on the RPE.
