The effects of low‐intensity exercise on cardiac glycogenesis and glycolysis in male and ovariectomized female rats on a fructose‐rich diet

We previously reported that low‐intensity exercise prevented cardiac insulin resistance induced by a fructose‐rich diet (FRD). To examine whether low‐intensity exercise could prevent the disturbances of key molecules of cardiac glucose metabolism induced by FRD in male and ovariectomized (ovx) female rats, animals were exposed to 10% fructose solution (SF) or underwent both fructose diet and exercise (EF). Exercise prevented a decrease in cardiac GSK‐3β phosphorylation induced by FRD in males (p
