Abstract

Patients with type 2 diabetes mellitus (T2DM) are at increased risk of developing neurodegenerative diseases. There is growing evidence that repeated exercise-induced transient increases in neurotrophic factors can augment neurogenesis and neuroplasticity. This pilot study compares the effects of 30-min submaximal cycling with those of exergaming (combining exercise and video gaming) at the same duration and same rating of perceived exertion (BORG RPE: 14-15) on serum neurotrophic factors in 8 elderly non-insulin-dependent T2DM patients (71±4 years) (2×2 crossover design). Brain-derived neurotrophic factor (BDNF), vascular endothelial growth factor (VEGF) and insulin-like growth factor (IGF)-1 levels were quantified using enzyme-linked immunosorbent assay (ELISA) kits. Heart rates were almost equal during cycling and exergaming, while lactate values were significantly higher during cycling (cycling versus exergaming: 3.7±1.1 versus 2.5±1.2 mmol/l, p<0.05). BDNF and VEGF levels were increased significantly post-cycling (+20%,+14%, p<0.05). No other significant pre-post changes were evident. This study demonstrates that acute exercise can increase neurotrophic factors (BDNF, VEGF) in elderly T2DM patients, depending on exercise mode.
