چکیده
عنوان مقاله [English]
The aim of this study was to investigate the effect of inspiratory muscle training at high altitude on Energy cost, peripheral capillary oxygen saturation and 1500m performance among endurance runners. The study was carried on a group of Twelve endurance male runners (age: 244.41±3.14yrs, height: 180.5±4.23cm, weight: 66.75±3.46 kg, Body mass index: 20.53±1.07) among Iranian national team were randomly divided into case and control group in hypoxic condition. Exhaustive testing free1500m, energy coast, strength Index and arterial oxygen saturation tests were taken before and 24hour after training period. Training program include same continues, interval, aerobic and resistance training for two groups. Runners performed 16 training session per week in high altitude within four weeks. Data were analyzed by analysis of variance (P≤0.05). Inspiratory muscle training at hypoxia due to significant decrease in 1500m running performance, inspiratory muscle strength and Energy coast in both group, but the differences in peripheral capillary oxygen saturation were not significant (P≤0.05). This study suggests that using inspiratory muscle training along with specified training in hypoxia increases inspiratory muscle strength and reduction in the work of breathing meanwhile it decreases ventilation and 1500meter running time in lower altitude.
