It has been shown that exercise not only improves insulin sensitivity and decreases glucose levels in patients with type 2 diabetes and metabolic syndrome (MacLeod et al., 2013; Malin et al., 2013), but also reduces coronary heart disease risk and improves exercise capacity (Golbidi & Laher, 2012; Malin et al., 2013; Sacre et al., 2014). Here, INS is linked to metabolic syndrome.
