Optimal Health Gains From HIIT and MICT
Study compares which workout provides the most benefits.
Adding to the debate over whether high-intensity interval training (HIIT) or moderate-intensity continuous training (MICT) is more effective, a recent review study by German researchers at Tübingen University found that HIIT and MICT each produce different health-enhancing outcomes. Investigators found that HIIT increased both aerobic and anaerobic fitness faster, showing more effectiveness in improving heart health and aerobic fitness. MICT, in contrast, was better at improving long-term glucose metabolism. On other health parameters, both training methods were equally effective.
Look for the study in Medicine & Science in Sports & Exercise (2021; 53 [3], 559–73).
