Repeated brief bouts of fast and intense exercise interspersed with low intensity exercise termed as high intensity interval training (HIIT) has shown to be a time-effective strategy to improve cardiorespiratory fitness in young and older. Moreover, HIIT has shown to improve glycemic control in patients at high risk for TDM2, muscle mass, body fat and physical function. However, there were many pending issues involving the HIIT for sarcopenia and cachexia in older people. For instance, the lack of access to physical activity facilities, such as the need for specific equipment (i.e. fitness equipment: treadmill, bike or resistance exercise equipment) and the need for high motor skill levels to performance the high-intensity exercise (i.e. run at high speed) have been reported as another reason to older people not to do HIIT.
