The Effect of eight-Week Endurance Training and Respiratory Muscles Training on the Pulmonary Function of Male Mountaineers

Sports exercises are beneficial in strengthening the respiratory system and improving the level of pulmonary function the purpose of the current study is analysis of the effect of eight-week endurance exercise and respiratory muscle training on the Pulmonary Function of male mountaineers.

  The current study is a clinical trial that includes a pretest and posttest. 30 male mountaineers of the Shahrood University of Technology. They were randomly divided into three groups of ten (1. Endurance training 2. Respiratory muscles training and 3. Control group). Before and after the training program, the Bruce test and spirometry test were given to the participants. The endurance-training group did the training for eight weeks that consisted of exercises three times a week and each session for 50 minutes. The respiratory muscles training group also did their exercises for eight weeks with 30 complete breathing with a power breath device. The dependent T-test was used to analyze the intergroup differences; the ANONA test was used to analyze the intragroup difference and the Bonferroni posthoc test was used to distinguish the groups which made a difference in the ANOVA test, with a significance level of P<0.05. 

Respiratory indices, slow vital capacity (SVC), vital capacity with pressure FVC, pressure expiratory volume in one second FEV1, peak expiratory flow (PEF), maximum expiratory flow (MVV), expiratory flow at 25-75% of vital capacity (25-75% %FEF) and VO2max index increased significantly in the respiratory muscle training group and caused a difference. In the endurance training group.

considering the results of the current study, it seems that using respiratory muscles training and endurance training can bring about an improvement in pulmonary function which was even more in the function of the respiratory muscles training group than in the endurance training group.
