CORRELATIONS BETWEEN BODY MASS INDEX AND HANDGRIP STRENGTH AND HANDGRIP ENDURANCE AMONG YOUNG HEALTHY ADULTS
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2015, Vol 2, Issue 27
Abstract
BACKGROUND: Physical inactivity has become a serious problem all over the world. Handgrip Strength (a form of isometric static contraction test), is an important test to evaluate the physical fitness and nutritional status of an individual. A number of factors like age, gender, body size, effort, skeletal muscle bulk and contractility may affect the handgrip strength (HGS) and handgrip endurance (HGE). AIM: This study was conducted to establish the possible correlation (if any) between body mass index and handgrip strength and endurance among young healthy adults. MATERIALS AND METHODS: A population based cross-sectional study comprising of 200 students (both male and female), age group-18-22 yrs was carried out in the Department of Physiology, Jorhat Medical College. Anthropometric parameters like height and weight were taken to evaluate the BMI and handgrip strength and handgrip endurance were taken by using handgrip dynamometer. According to WHO classification of BMI, subjects were categorized into three groups as underweight BMI ≤18.5 kg/m2 , normal weight BMI 18.5-24.9 kg/m2 and overweight BMI≥ 24.9 kg/m2 . Gender wise difference was analyzed by unpaired t test. Statistical analysis for correlation was done by using Karl Pearson’s Correlation Coefficient denoted by(r). RESULT: Males had higher handgrip strength and handgrip endurance than females. Statistically significant correlation was found between BMI and handgrip strength & endurance in underweight & overweight subjects. Gender differences in correlation were observed in correlation between BMI & HGS and HGE. CONCLUSION: The observed influence of BMI and gender differences in correlation between BMI and HGS and HGE indicate that besides BMI several other factors like effort, strength, muscular contractility etc. affect muscular strength & endurance in young males and females.
