High-Intensity Interval Training as an Efficacious Alternative to Moderate-Intensity Continuous Training for Adults with Prediabetes
Table 3
Changes in fitness and cardiometabolic parameters (mean [SD]) before and 1 month following intervention for study participants randomized to high-intensity interval training (HIIT, ) and moderate-intensity continuous exercise (MICT, ) and overall () effect of time. The current results represent per-protocol analysis.
