Abstract

Background: Muscular strength of the adult population is the key factor for their potency. Dominant hand plays an important role in most of the daily muscular activities and sport activities. There are many factors which may affect the handgrip strength and very few studies especially in India have shown their correlation with handgrip strength. Aims and Objectives: The cross-sectional study was carried out to find the correlation of age, body height, body weight, body mass index (BMI), waist circumference (WC), waist to hip ratio (WHR) and hand span of dominant hand with dominant handgrip strength in adult males and females. Material and Methods: The study included 121 healthy adults, 76 males and 45 females. All the parameters to be studied were measured using the standard methods and dominant handgrip strength was measured using the standard adjustable digital hand grip dynamometer in both males and females. Statistical Analysis: The data was analysed by Pearson’s correlation coefficients and 5% level of probability was used to indicate the statistical significance. Results: The dominant hand’s grip strength in males (M) and females (F) have significant positive correlation (P < 0.05 – 0.001) with body height (r = 0.245 (M), 0.379 (F)), body weight (r = 0.497 (M), 0.484 (F)), BMI (r = 0.428 (M), 0.350 (F)) and hand span of dominant hand (r = 0.761 (M), 0.418 (F)). Whereas handgrip strength in subjects have non- significant weak positive correlation ship (P > 0.05) with WC (r = 0.180 (M), 0.102 (F)) and WHR (r = 0.058 (M), 0.101 (F)). Conclusion: Our study showed the significant positive correlation of dominant hand’s grip strength with age, body height, body weight, BMI and hand span of dominant hand. Weak positive but not significant, correlation of handgrip strength was also observed with WC and WHR. More research work is needed to obtain the precise correlation of these variables with handgrip strength of dominant hand
