Abstract :

Objectives: The aim of the study was to compare total and regional body composition and their relationship with glucose homeostasis in physically active and non-active c-SCI individuals. Methods: Individuals with lesion level between C5-C7 were divided into two groups: Physically active (PA n=14; who practiced physical exercise for at least 3 months, 3 times/week or more, minimum of 150 minutes/week): and non-physically active (N-PA n=8). Total fat mass (t-FM) and regional fat mass (r-FM) were assessed by dual energy X-ray absorptiometry (DXA). Fasting plasma insulin (FPI) was determined by ELISA. Results: PA group present lower (p<0.01) total fat mass (t-FM), % and Kg, regional fat mass (r-FM), % and Kg, FPI levels and HOMA index, while they had higher (p<0.001) total free fat mass (t-FFM), %, and regional free fat mass (r-FFM), %, compared to the N-PA group. In the N-PA group, FPI and HOMA index were negatively (p<0.05) correlated with FFM% (r=-0.71; r=-0.69, respectively) and positively correlated to trunk-FM (r=0.71, r=0.69, respectively) and trunk-FM:t-FM (kg) ratio (r=0.83, r=0.79, respectively). Conclusion: Physical exercise is associated with lower t-FM, r-FM and insulin resistance, which could contribute to the decrease of the risk of cardiovascular and metabolic conditions in c-SCI individuals.
