Health status of older adults with Type 2 diabetes mellitus after aerobic or resistance training: A randomised trial
A prior study showed positive effects of resistance training on health status in individuals with diabetes compared to aerobic or no exercise, the exercise regimens were either different in volume, duration or rate of progression. We aimed to compare the effects of progressive resistance training (PRT) or aerobic training (AT) of similar volume over an 8-week period on health status (measured using the Short-form 36 Questionnaire) in middle aged adults with type 2 diabetes mellitus (T2DM).
Sixty subjects aged 58 (7) years were randomised to PRT (n = 30) or AT (n = 30). General health and vitality were significantly improved in both groups (mean (SD) change scores for PRT were 12.2(11.5) and 10.5(18.2), and for AT, 13.3(19.6) and 10.0(13.1), respectively) and exceeded the minimally important difference of 5 points. The PRT group also had improved physical function and mental health status (mean (SD) change scores: 9.0(22.6), p < 0.05 and 5.3(12.3), p < 0.05, respectively), which was not observed in the AT group. However, the between group differences were not statistically significant.
Both exercise regimens have positive impact on health status that correlated well with clinical improvement in patients with T2DM. PRT may have some additional benefits as there were significant changes in more domains of the SF-36 than that observed for the AT group.
