Figure 4From: Effect of interval training intensity on fat oxidation, blood lactate and the rate of perceived exertion in obese men The concentration of blood lactate (BLa) during 4-week training of MIIT (a) and HIIT (b); data collected in the first exercise session of every week; data represented as mean ± SEM. Note: workload at 30 mins of MIIT was lower than workload at 5 and 15 mins of MIIT. There was a significant effect of training period (weeks) (p ≤ 0.001). MIIT-1-4: moderate-intensity interval training at weeks 1, 2, 3 and 4; HIIT-1-4: high-intensity interval training at week 1, 2, 3 and 4.Back to article page
