High-intensity interval training (Wingate-based HIIT) has been shown to induce similar adaptations as traditional training at a moderate intensity following 6 wk of training in healthy adults despite the lower training volume (5). This suggests that HIIT may be a time-efficient alternative (6). Recently, HIIT was also reported to rapidly induce adaptations that are linked to improved health-related outcomes in sedentary and overweight/obese individuals (7, 8).
