Type: article
Abstract: Background : The effect of physical activity on diet-induced thermogenesis is still controversial. Irisin is a new protein that is secreted from the muscle into the circulation after acute exercise and induces browning of adipocytes. The purpose of the present study was to examine whether the changes in serum irisin levels following a single bout of exercise could modulate diet-induced thermogenesis. / Methods : Nine normal-weight healthy young volunteers (32±4 years) participated in two experiments performed in a random order. In the exercise trial, 40 min of exercise on a bicycle ergometer at 60% of heart rate reserve were performed on the day before the assessment of energy expenditure. Blood concentrations of irisin, glucose and insulin were measured before and after the intake of a fixed 860 kcal meal. Serum irisin levels were also examined before and immediately after the exercise. In the no exercise trial, energy expenditure was assessed without previous exercise....
