Effects of aquatic high intensity interval training on parameters of functional autonomy, mental health, and oxidative dysfunction in elderly subjects with type 2 diabetes

The present study investigated the effects of aquatic exercise on parameters of functional autonomy, mental health, and oxidative dysfunction in elderly patients with DM2. A total of 130 elderly were included in the longitudinal clinical study and were attributed to the non-diabetic group (n = 27) and diabetes the group (n = 22). Both groups participated in 24 sessions of Hydro-HIIT, 48 h before and after Hydro-HIIT, the GDLAM index, depression, and anxiety scores and markers of oxidative dysfunction were quantified. After intervention, GI decreased in both groups (non-diabetes group = −24%; diabetes group = −22%) (p < 0.05), markers of depression (−46%), anxiety (−60%), DCFH-DA (−55%), SOD (+59%), TNF-α (−37%) and IL-1 (−48%) in diabetes group (p < 0.05). The intervention with Hydro-HIIT improves aspects related to functional autonomy, mental health, and exerts consequently, a modulating effect on oxidative stress and inflammatory response in elderly people diagnosed with DM2.
