Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The MICT group is the standard care group and will be instructed to walk for 30 minutes, 5 days per week at a moderate intensity. The goal is to accumulate 150 minutes of continuous aerobic exercise each week. Participants will be instructed on the use of the Rating of Perceived Exertion (RPE) scale during baseline testing and will be instructed to reach an RPE of 12-16. A heart rate monitor will be worn to monitor exercise intensity. Heart rate should reach \~70% of maximal heart rate.
The IT group will perform 5 body-weight exercises in three progressive phases. During the first 2 weeks the circuit will be completed twice, 30 second intervals, 90 seconds of rest. The exercises will be performed on 3 days of the week with at least one day of rest between exercise days (ideally Monday, Wednesday, Friday). The number of repetitions will increase to a maximum of 4 while the interval and rest periods increase to a maximum of 45 seconds each. The total time spent performing intervals by week 8 will be 15 minutes. A 2 minute warm up and 3 minute cool down will be performed, such as jumping jacks or simply walking. A heart rate monitor will be used to measure exercise intensity. Heart rate should reach approximately 90% of heart rate max during the intervals. Participants will be instructed on the use of the Rating of Perceived Exertion scale during baseline testing and will be instructed to reach an RPE of ≥17 during the high intensity intervals.
