Abstract
BACKGROUND: We examined whether aerobic exercise could have an impact on anthropometric and metabolic parameters of type 2 diabetes mellitus (T2DM) Cameroonian women aged ≥50 years. METHODS: We enrolled 23 T2DM Cameroonian women aged ≥50 years regularly followed at the National Obesity Center of Yaounde, Cameroon, in a 12-week aerobic exercise program monitored by a pedometer. Exercise intensity was progressively set between 55% and 75% of maximum heart rate. We measured weight, body mass index (BMI), fat, lean mass, visceral fat, maximum oxygen uptake, glycaemia and insulin tolerance index at baseline, after six and twelve weeks. A mixed ANOVA model was used to evaluate changes of outcome measures over time. RESULTS: Total body weight was significantly reduced after 12 weeks (P<0.05), waist circumference after 6 and 12 weeks (P<0.05). There was an increase of the lean mass from 6 weeks (P<0.001) and a reduction of the mean visceral fat at 12 weeks (P<0.001). At the end of the program, the mean glycaemia was significantly decreased (P<0.05), and the maximum oxygen uptake was enhanced (P<0.05). CONCLUSIONS: The 12-week aerobic exercise program improved the anthropometric and metabolic parameters as well as the aerobic capacity of T2DM Cameroonian women aged ≥50 years.
