- Abstract
Purpose: This study investigated the cardiometabolic health of overweight/obese untrained individuals in response to 8 weeks of HIIT and MICT using a field approach, and to 4 weeks of training cessation (TC). Methods: Twenty-two subjects performed 8 weeks of moderate intensity continuous training (MICT—n = 11) or high-intensity interval training (HIIT—n = 11) (outdoor running), followed by 4 weeks of TC. Cardiorespiratory fitness, body composition, arterial blood pressure, glucose metabolism and blood lipids were measured pre-training (PRE), post-training (POST) and TC. Results: HIIT improved eight indicators of cardiometabolic health ( V O 2 max , BMI, body fat, visceral fat, systolic blood pressure, total cholesterol, fasting glucose and triglycerides—p < 0.05) while MICT only three ( V O 2 max , BMI, and visceral fat—p < 0.05). After 4 weeks of TC, four positive adaptations from HIIT were negatively affected ( V O 2 max , visceral fat, systolic blood pressure and total cholesterol—p < 0.05) and three in the MICT group ( V O 2 max , BMI and visceral fat, p < 0.05). Conclusion: Eight weeks of HIIT performed in a real-world setting promoted a greater number of positive adaptations in cardiometabolic health of individuals with overweight/obese compared to MICT. Most of the positive effects of the HIIT protocol were also found to be longer lasting and maintained after the suspension of high-intensity interval running for 4 weeks. Conversely, all positive effects of MICT protocols were reversed after TC.
