Glycemic reductions following water- and land-based exercise in patients with type 2 diabetes mellitus

Abstract Purpose To assess the acute glucose responses to the first sessions of three mesocycles of water- and land-based aerobic exercise. Methods The water-based exercise group (WBE, n = 14; 54.1 ± 9.1 years) performed deep water walking and/or running, while the land-based exercise group (LBE, n = 11; 60.1 ± 7.3 years) performed walking and/or running on athletic track. In the first mesocycle, patients trained at 85–90% of their anaerobic threshold (AT) for 35 min, progressing to 90–95% of the AT in the second mesocycle, and 95–100% of the AT in the last mesocycle. Capillary glucose was assessed before and immediately after the first session of each mesocycle. Results There was glycemic reduction (p  Conclusions The acute response of blood glucose to aerobic training between 85 and 100% of the heart rate of AT is effective and independent of the environment in which it is performed.
