Effects of a Low-Volume Aerobic-Type Interval Exercise on V˙O2max and Cardiac Mass

Abstract

Our study revealed that V˙O2max improvement with the HIAT was greater than with the CAT despite the HIAT being performed with a far lower volume and in far less time than the CAT. This suggests that the HIAT has potential as a time-efficient training mode to improve V˙O2max in sedentary adults.
