Role Of BMI On Hand Grip Force With Respect To Gender.
Biomedica Jan ;34(2):108-12.

Background and Objectives: Hand Grip Force is due to extreme voluntary force of flexors of fingers. Muscle fatigue causes decline in grip force. We aim to observe the role of Body Mass Index (BMI) in connection to Maximum and Mean Grip Force in young boys and girls of Shalamar Medical & Dental College, Lahore, through Power Lab. Methodology: The duration of this study analytical cross-sectional study was from November 2014 to February 2017. Convenience Sampling Technique was used and thirty participants with equal number of boys and girls were selected. All were between 20-23 years of age and consented after the explanation of the research procedure. They all were with good health and with no history of present illness or on any medication nor involved in any physical fitness training procedures. Power Lab Model 26T along with Hand Grip Transducer as hardware and Lab tutor as software were selected to get Grip Force values for each participant. Direct values in percentages were obtained by following the instructions given on the respective window for recording and calibration. To record weight and height of each subject Adult Weighing Scale ZT-160 was used. Results: Increased Grip Force values was observed in boys compared to girls by > 300% for Maximum Grip Force, > 33% for average grip force and > 58% for maximum grip force just before fatigue. A direct relation was observed between BMI and Grip Force values in boys, although in girls this relation was inverse for Maximum grip force and Grip Force just before fatigue, while direct relation for Average Grip Force values. Conclusion: In boys the BMI was directly proportional to Hand Grip Force. However, in girls, it was in inverse relation with Maximum value and Grip Force values just before fatigue; but directly related with Mean Grip Force.
