CORRELATION OF UPPER AND LOWER LIMB STRENGTH WITH BODY MASS INDEX AND WAIST TO HIP RATIO IN YOUNG ADULTS

Background: Body mass index (BMI) and waist-to-hip ratio (WHR) indicate body fat distribution, which can reduce muscle strength. The objective of this study was to determine the correlation of upper limb strength and lower limb strength with BMI and WHR in young adults. Methods: This cross-sectional study was conducted on a total of 105 young healthy adults (18–25 years) recruited from a medical college with convenience sampling. Span of study was six months from 1 May 2023 after approval from the Institutional Ethical Review Board. Manual Muscle Testing (MMT) was used to measure the strength of upper extremity and for lower limb strength 30 seconds sit to stand test (STS) and 20 m shuttle run test (SRT) were utilized. Pearson correlation test was run to find correlations. Results: WHR and BMI had a statistically significant but mild correlation (p=0.01, r=0.26). BMI was significantly correlated with MMT of Finger flexors and 30 sec-STS (p?0.05). BMI with upper limb strength and lower limb strength was not found to be correlated (p>0.05). WHR had no statistically significant correlation with strength of shoulder abductors, biceps and finger flexors, 20 m shuttle run test and 30 sec sit-to-stand test. Conclusion: Positive correlation was present between BMI and WHR. Strength of finger flexors, shoulder abductors and bicep muscles were significantly correlated with lower limb strength. Body Mass Index and Waist to Hip Ratio decreased finger flexors strength and 30 seconds sit to stand repetitions.
