Cardiometabolic Effects of Combined Aerobic Exercise and Non-Exercise Physical Activity

Aerobic exercise will be performed on the treadmill at 40-60% of the participants' heart rate reserves. Each aerobic exercise session will last for 40 minutes. All participants will be monitored with a heart rate monitor throughout the exercise sessions. During the first three-week, participants will exercise on the treadmill at intensities between 40-50%, and between fourth and eighth weeks, 50-60% of their heart rate reserves. Participants will wear an accelerometer on their non-dominant wrist during the intervention to monitor the physical activity and sedentary behavior data. At the same time, these participants will be asked not to change their routine diet during the intervention period.

Participants who will carry out this intervention will increase their non-exercise physical activities. Before intervention period, participants will receive face-to-face training to increase their non-exercise physical activities. This training will generally consist of recommendations based on the study which effectively reduced sedentary behavior (SB) with non-exercise physical activities (Sarah Kozey-Keadle et al. 2012). A one-on-one interview will be held with each participant every week to learn about strategies by which the volunteers successfully increased their non-exercise physical activities in the previous week, and the difficulties or barriers they encountered. New strategies to overcome these difficulties and barriers will be discussed and suggestions will be made. Participants will wear an accelerometer on their non-dominant wrist to monitor the physical activity and SB data, and will be asked not to change their routine diet during the intervention period.
