MVIT, or low volume high intensity training, involves repetitions of ‘all out’ maximal volitional effort, typically for 30 seconds, followed by a recovery period. In addition to AIT another form of HIIT, maximal volitional interval training (MVIT) has also been well described. A common model for studies using HIIT (high intensity interval training) in populations with or at risk of cardiac disease is an AIT (aerobic interval training) prescription of 4 or 5 work bouts each of 3 to 4 minutes duration, done at around 85% to 90% of maximal heart rate, followed by a recovery period. The ‘lack of time’ barrier has been addressed recently both in patients with chronic conditions and also in those at risk of cardiometabolic disease by the introduction of high intensity activity programs, which reduce the time required to exercise compared to low intensity programs. Barriers to achieving a regular physical activity program include lack of time, lack of access to exercise facilities and lack of motivation. Physical activity has multiple health benefits and is a key component of many lifestyle programs aimed at improving physical fitness and reducing cardio-metabolic risk –.
