Aim: To determine whether height, body mass index (BMI), hand length, and hand breadth were predictive of hand grip strength in healthy Punjabi adult males and females.
Materials and methods: This cross-sectional study recruited 100 healthy adult males (50) and females (50) in the age group of 50 to 60 years randomly. Their anthropometric characteristics including height, weight, BMI, hand length, and hand breadth were measured using standard techniques. Hand grip strength was measured using Jamar dynamometer. Data were analyzed using Student's t-test and analysis of variance (ANOVA).
Results: The present study generated the normative data for hand grip strength and its association with gender, height, weight, BMI, hand length, and hand breadth in study subjects. The gender difference in grip strength was statistically significant with higher grip strength found in males than females. Also, it was found that grip strength was more in the dominant hand as compared with the nondominant hand. Subjects with longer and broader hands had stronger grip.
Conclusion: The knowledge of determinants of hand grip strength in a normal population is essential as in clinical settings it is used as an indicator of overall physical strength and health. Hand length and hand breadth should be well thought out for hand grip strength measurements in the older age group since these anthropometric measures could affect the results of treatment and control of hand function.
