INS and Insulin resistance: This may result in better plasma glucose handling, hence, lower insulin concentrations as observed in the 70 % T. Indeed, research data has revealed that exercise-induced glycogen depletion and enhanced glycogen synthase activity may contribute to the improvement of insulin sensitivity and attenuated insulin resistance.43, 44, 45 The results were in agreement with a similar study using hyperlipidemic participants, which demonstrated that exercising at 40–70 % intensities not only attenuated PHTG, but also lowered insulin response.28
