4x4 HIIT yields greater VO2max gains than shorter HIIT or MICT in overweight adults; extends RCT evidence guiding protocol selection.
Does high-intensity interval training improve maximal oxygen uptake compared to moderate-intensity continuous training in overweight and obese individuals?
A 4x4-minute high-intensity interval training protocol is superior to 10x1-minute HIIT and moderate-intensity continuous training for improving V˙O2max in overweight and obese individuals.
