A072: Study on Respiratory Muscle Training Impact on Static Lung Functionin Amateur Runners

<bold>Objective:</bold> Respiratory muscle training (RMT) is a specialized training method targeting the strength and endurance of respiratory muscles, aimed at enhancing lung function and the adaptability of the respiratory system. Common training techniques in RMT include deep breathing, inspiratory muscle training, expiratory muscle training, and diaphragm training. It is generally applicable to athletes, individuals with lung function impairments, the elderly, and those requiring high-intensity respiratory efforts. This study aimed to investigate the effects of an 8-week RMT on static lung function in amateur runners, comparing the performance between the training and control groups to determine the effectiveness of RMT. <bold>Methods:</bold> This study recruited 40 amateur runners, randomly assigning them to either the training or control group, with 20 individuals in each. Both groups continued their regular running exercises according, but the training group additionally underwent an 8-week RMT, with three 30-minute sessions per week. The control group maintained their routine without any pulmonary training. Pre- and post-training, static lung function parameters including VC, VE, BF, FVC, FEV1, and MVV were measured using a static lung testing device, followed by comparative analysis. <bold>Results:</bold> The findings showed that after the 8-week RMT, significant improvements (P &lt; 0.05) were observed in the pulmonary function indicators of the training group, while the control group didn't exhibit as notable improvements. Specifically, the training group experienced a 7.1% increase in VC (Vital Capacity), a 6.2% increase in VE (Minute Ventilation), a 4.5% reduction in BF (Breathing Frequency), a 9.4% increase in FVC (Forced Vital Capacity), a 10.2% increase in FEV1 (Forced Expiratory Volume in 1 second), and an 8.6% increase in MVV (Maximum Voluntary Ventilation). <bold>Conclusion:</bold> In conclusion, on top of regular running exercises, RMT significantly improved static lung function in amateur runners. These results indicate that RMT is an effective method for pulmonary function training, enhancing lung function levels in amateur runners, which indirectly elevates their physiological levels, thereby improving running capability.
