description | Introduction: Muscle strength and endurance are key
determinants of physical fitness, cardiometabolic profile, and
overall health. Clinically, they are tested by estimating Handgrip
Strength (HGS) and Handgrip Endurance (HGE) through an
isometric contraction of the flexors of the forearm and hand.
Body Mass Index (BMI) and body fat content can both influence
muscle performance, but there are wide variations regarding
their effects. BMI and body fat also do not show unequivocal
similarity to each other.
Aim: The aim of this study was to determine and compare
the effects of BMI and body fat on muscle strength and
endurance.
Materials and Methods: A descriptive cross-sectional study was
conducted at the Department of Physiology, Himalayan Institute
of Medical Sciences, Swami Rama Himalayan University, Jolly
Grant, Dehradun from April 2019 to March 2020. A total of 100
subjects who fulfilled the selection criteria were included. BMI and
body fat were measured, and HGS and HGE were recorded using
a handgrip dynamometer. Statistical analysis was performed
using SPSS version 17.0. Descriptive statistics, independent
sample t-test, and one-way ANOVA were used for comparison.
Pearson’s correlation coefficient and linear regression were used
to determine and quantify the nature of the effect, with a p-value
of ≤0.05 considered statistically significant.
Results: The participants had a mean BMI of 23.809±3.798 kg/
m2
and a mean body fat percentage of 25.309±7.162%. The
mean HGS and HGE of the participants were 36.08±9.956 kg
and 18.46±14.2 seconds, respectively. Body fat percentage
showed a negative and moderately significant correlation
(p-value≤0.001) with both muscle strength and endurance.
Approximately one-fifth of the variations in muscle strength and
one-third of the variations in muscle endurance were determined
by body fat content. HGS and HGE were higher in males, while
body fat percentage was higher in females. Gender variation in
body fat contributed to more than 40% of the variance.
Conclusion: The study revealed a negative correlation between
total body fat and muscle strength and performance. Keeping
body fat under control can improve muscle performance, which,
in turn, enhances cardiometabolic health. |
