ABSTRACT
This research aimed to investigate the effects of swimming and inspiratory muscle training intervention on swimmers’ performance. The subjects were 18 males and 10 females Taipei high school. All the subjects were grouped into experimental group and control group according to their gender, age and swimming performance. In the experimental group, the subjects received inspiratory muscle training of 80% PImax; the control group received 20% PImax once a day, 30 times once, five days a week for six consecutive weeks. Meanwhile, a test of maximal respiratory muscle strength was administered at the fourth week to modify the intensity. The experiment was of eight weeks’ duration. It included basic practice for the experiment and pre-test in the first week, six weeks of respiratory muscle training and post-test in the last week. The data was analyzed with Two-Way Mixed Design ANOVA to examine the variables such as pulmonary function, respiratory muscle strength, swimming performance and self awareness of breathlessness before and after the intervention, with t-test design to examine the variables such as heart rate, blood lactate level. The analysis results are interaction, while the simple main effects were analyzed, if significant, post hoc comparisons to LSD method. The results showed that after six weeks’ inspiratory muscle training intervention (1) the maximal inspiratory muscle strength in the post-test was superior to that in the pre-test (145.78±31.64 cmH2O vs. 116.89±29.08 cmH2O) (p<.05) (2) the FVC and FEV1 ratio in the post-test was significantly higher than that in the pre-test (4.69±0.96 l vs. 4.07±0.90 l;4.12±0.79 l vs. 3.76±0.84 l) (p<.05) (3) the FEV1/FVC% in the pre-test was significantly higher than that in the post-test (92.54±3.92% vs. 87.37±7.29 %) (p<.05) (4) the swimming performance in 50M post-test was better than the pre-test (27.62 ±2.57 sec. vs. 28.60±2.97 sec.) and in 100M as well (60.14±4.64 sec. vs. 61.45±4.64 sec.) (p<.05). (5) there was no significant difference in the aspect of the difference rate of heart beat of pre-test and post-test in 50M and 100M (p>.05). (6) there was no significant difference in the difference rate of the blood lactate level in the pre-test and post-test of 50M and 100M (p>.05). (7) there was no significant difference between selfawareness of breathlessness in the pre-test and post-test (p>.05). In conclusion, six consecutive weeks’ inspiratory muscle training had a beneficial effect on the performance of youth elite swimmers.
