Abstract
BACKGROUND: Malnutrition refers to excesses, deficiencies or imbalance in a person's intake of energy and/or nutrients. The term Malnutrition addresses 3 broad conditions like undernutrition, micronutrient related malnutrition and overweight, obesity & diet related non-communicable diseases. The under nutrition includes wasting, stunting, underweight and deficiencies in vitamins and minerals. As the pandemic of overweight around the globe continues to rise, many countries face a double burden of overnutrition and undernutrition. Altered nutritional status is known to impact several physiological functions of the body. Skeletal muscle function indices have been advocated for the assessment of nutritional status. Skeletal muscle functions can be assessed by their parameters like skeletal muscle work done, muscle strength and endurance. AIM OF THE STUDY: To test the hypothesis that altered nutritional status is associated with poor functional ability and the role of nutrition in the muscle functions of young adult population. MATERIALS AND METHODS: This is a Cross Sectional study involving 200 male Persons belonging to the age group of 18-25yrs. According to WHO and Asia pacific guidelines for obesity, the subjects were classified into underweight (< 18.5 kg/m2), normal (18.5–22.9 kg/m2), overweight (23–24.9 kg/m2), and obese (≥ 25 kg/m2). Muscle function parameters namely Maximum Voluntary Contraction in Kgs (MVC), Endurance Time in seconds (ET) were measured using Hand grip dynamometer. Work done was calculated using Mosso’s ergograph. Comparison between groups for all measured variables was done using one way ANOVA. Statistical Analysis was done using SPSS software. RESULTS: The mean value of Workdone in normal subjects was 55.18 Kg.m2.s-2 which was higher than underweight, overweight and obese with the mean value of 25.80 Kg.m2.s-2, 47.46 Kg.m2.s-2, and 34.84 Kg.m2.s-2 respectively. The mean value of Maximum Voluntary Contraction (MVC) in normal subjects was 21.26 Kgs which was higher than underweight, overweight and obese with the mean value of 8.88Kgs, 16.80Kgs, and 12.70Kgs respectively. The mean value of Endurance Time (ET) in normal subjects was 31.16 Seconds which was higher than underweight, overweight and obese with the mean value of 11.38 Seconds, 28.16 Seconds, and 24.96 Seconds respectively. CONCLUSION: Our study concluded that the normal subjects had greater muscle strength, work output and longer endurance than obese, overweight and underweight subjects. One's nutritional status would lead to specific levels of body mass, which in turn has been found to correlate directly to muscle strength and endurance.
