TO STUDY THE CORRELATION BETWEEN FATIGUE AND BODY MASS INDEX (BMI) USING MOSSO'S ERGOGRAPH IN YOUNG ADULTS

Muscles are the only tissues in the body that have the ability to contract and hence move the other parts of the body. The strength of any given muscle, in terms of force exerted on the skeleton depends upon length, shortening speed, cross-sectional area, sarcomere length, myosin isoforms and neural activation of motor units. Fatigue is a reversible physiological state in which there is an objective reduction in the performance or it's absence resulting from continuous or prolonged activity. The degree, duration and type of work are the important factors that affect the performance and onset of fatigue. To correlate body mass index (BMI) and muscle fatigability in young healthy adults. This cross sectional study included 100 apparently healthy young adults, both males and females between 18-24 years of age and without a history of alcohol or tobacco consumption, history of any cardiovascular disorders or diabetes mellitus and any drug history like corticosteroids, beta blockers. and underwent fatigue test using Mosso'sErgograph and the work done (Kgm) was calculated and correlated with body mass index. The results showed a strong positive correlation between Body Mass Index and work done(r=1) which was found to be statistically significant (p<0.05). Moreover, The results showed a very strong positive correlation(r=1) between different categories of Body Mass Index and the amount of work done by the exercising muscle, but the results were statistically non significant (p<0.05) in all the sub categories of body mass index. A strong positive correlation between Body Mass Index and amount of work done by the exercising muscle suggests that the level of fatigueness in an individual is related to his/her nutritional status and physical fitness.
