Comparison of muscle fatigue in prediabetic and normal individuals

Abstract

It was observed that people with prediabetes had greater performance fatigability of the knee extensors due to contractile mechanisms compared with controls, although less performance fatigability than that of people with Type 2 Diabetes Mellitus. The aim of this study was to compare muscle fatigue in normal and prediabetic individuals. A comparative cross- sectional study was conducted in adults between 24-60 years of age.A total of 100 age matched normal and 100 prediabetic individuals were selected for the study. Fatigability was calculated as a function of work done by the pleximeter finger of the dominant hand. The work done was categorized broadly into four groups viz. 0-2 kg.m, 2.1-4 kg.m, 4.1-6 kg.m and 6.1 and above. Fatigue test was performed using Mosso’s Ergograph. The study was conducted at Rajarshi Dashrath Autonomous State Medical College, Ayodhya. Overall, average work done by prediabetic individuals was lesser (0-2 kg.m=23%, 2.1-4 kg.m=58%, 4.1-6= 17% and 6.1 and above=2%) as compared to normal individuals (0-2 kg.m= 20%, 2.1-4 kg.m= 48%, 4.1-6= 27% and 6.1 and above= 5%).T
