Purpose: This study examines the association amid hand grip strength (HGS) and peak expiratory flow rate (PEFR), while controlling for height, weight, and body mass index (BMI).
Methods: A cross-sectional study was carried out on healthy young adults, measuring HGS and PEFR. Multiple regression was applied separately for male and female participants. To evaluate the independent contribution of HGS to PEFR, zero-order, partial, and part correlations were calculated after adjusting for height, weight, and body mass index (BMI).
Results: HGS depicted a significant positive correlation with PEFR in both male (r = 0.353, p = 0.007) and female (r = 0.245, p = 0.041). In regression analysis, HGS persisted a significant predictor of PEFR in male (β = 0.385, p = 0.015) and female (β = 0.293, p = 0.035) after adjusting for height, weight, and BMI. Other anthropometric variables showed weak and non-significant associations with PEFR. The partial correlation of HGS with PEFR was r = 0.329 in men and r = 0.258 in women, indicating its independent contribution beyond body composition measures.
Conclusion: HGS emerged as a significant and independent predictor of PEFR, underscoring the importance of muscle strength in pulmonary function. These results indicate that HGS assessment may serve as a practical, non-invasive method for evaluating respiratory health in both clinical and fitness environments.
