Abstract:
Introduction: An increased popularity of the marathon running and has been used widely as a model to investigate the limits of physiological function. Sufficient capacity of the respiratory system to meet the endurance exercise demands pressure-generating potential from the respiratory muscles. Marathon running is sufficient to induce substantial reductions in pulmonary function which are directly influenced by aspects of respiratory muscle fatigue. The respiratory muscle fatigue has been evidenced by decrements in inspiratory and expiratory mouth pressures, FEV1, FVC and MVV. The effectiveness of stretching protocols on the muscular systems are known and hence are given to recover from fatigue of the endurance run. These mostly comprise of the lower body stretches but the respiratory muscle fatigue is left to the time course recovery. The effect of Chest Wall Stretching on dynamic pulmonary function parameters among Healthy Marathon Runners remains unexamined. Therefore, the main purpose of the study was to observe the effect of Chest Wall Stretching on pulmonary function parameters like FVC, FEV1, MVV, SpO2, RR, PR changes in 21k marathon runners.

Materials and Methodology: Study design was Quasi-Experimental study design. Study was conducted on 8th edition of Shaheed Marathon 21k Runners. Sampling method used was convenient sampling on a sample size of 60 subjects. Elite Normal healthy 21k runners of age group 25-45 years, both male and female with normal BMI were included in the study. Subjects with any respiratory, cardiac, musculoskeletal and neurological pathology with 5k and 10k runners were excluded.

Results: Significant changes in pulmonary function parameters with FVC, MVV, SpO2, RR and PR (p=<0.0001) was seen showing increase in their ventilatory volumes. FEV1 (p=0.03) showed significant improvements in individual groups but in comparison there was no statistical significance in between the two groups in 21k marathon runners.

Conclusion: It can be concluded that Chest Wall Stretching is significantly effective in improving the Ventilatory Parameters thus, reducing the acute effects of respiratory fatigue, of the Marathon Runners in comparison to Conventional Lower limb Streching hence it can be incorporated as one of the Therapeutic Stretching maneuvers after endurance running.
