Effects of Different Types of Physical Activity on Respiratory Health Parameters in Elderly Males: A Cross-Sectional Study.

Background  is a global phenomenon associated with declines in muscle mass, physical activity levels, and respiratory health among elderly individuals. Despite evidence suggesting the benefits of physical activity on respiratory function, there is limited research examining its effects on lung function in the Indian elderly population. Materials and methods This cross-sectional study aimed to investigate the impact of different intensities of physical activity on respiratory health parameters among apparently healthy elderly males aged 60-80 years. Participants were categorized into walking, swimming, and sedentary groups based on their level of physical activity. Anthropometric measurements, cardiovascular parameters, respiratory endurance tests, and spirometry were conducted to assess lung function. Statistical analysis included nonparametric tests to compare the groups. Results Age, height, weight, BMI, waist circumference, and hip circumference were similar across groups, but the waist-to-hip ratio was higher in the sedentary group. Systolic and diastolic blood pressure did not differ significantly, while the pulse rate was lower in the swimming group. The sedentary group exhibited lower respiratory endurance, with a significantly reduced 40 mmHg endurance test and maximum expiratory pressure compared to the walking and swimming groups. Spirometry results showed significant improvements in various parameters, including forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), peak expiratory flow rate (PEFR), forced expiratory flow 25% (FEF-25), and maximum voluntary ventilation (MVV) in the walking and swimming groups compared to the sedentary group. Conclusion Regular physical activity, particularly walking and swimming, appears to positively influence respiratory health parameters among elderly males. Engaging in these activities may enhance respiratory muscle strength and lung function, potentially mitigating age-related declines in pulmonary function and promoting overall well-being.
