Upon completing informed consent, all the eligible participants will have their body composition measured at the Exercise Nutrition Research Laboratory, Western University, using non-invasive air displacement plethysmography (BodPod). This requires participants to sit in a chamber while space [volume] their bodies take up is assessed. This along with their body mass allows body density [d=m/v] and body composition to be determined pre and post the 5-week exercise intervention. Upon completing the body composition measurements, participants will have their endurance capacity assessed by performing a timed one-mile run (which will be used as an index of their endurance capacity). Participants will be advised to dress appropriately for physical activity including proper footwear.
Each participant will be matched to either HIIT or MCEET group based on their one-mile run time. The HIIT group will perform six, 20-second bouts of high-intensity interval exercise separated by 2 minutes of active recovery (walking) while the MCEET group will perform 14 minutes of continuous endurance exercise at 70% of Maximum Heart Rate (MHR). Both exercise protocols will include 3 minutes of warm up and cool down at a 30% MHR, for a total of 20 minutes for each treatment. The first week of the exercise intervention will consist of one-on-one supervised treadmill training, three times per week in the lab. From week two to five, participants will follow the same exercise program on their own at their preferred gym three times per week in order to examine free-living individuals adhere to two exercise programs.
All participants will log their heart rate before, during, and immediately after each training session using a free heart rate monitor mobile App to ensure safety and achievement of their targeted heart rate. Further, they will complete two validated questionnaires [physical activity enjoyment scale and exercise adherence rating scale] as well ratings of perceived exertion scale after the 6th, 9th and 15th session. Finally, no attempt will be made to modify the participants daily diet, but a 3-day food log will be collected to assess food intake.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||40 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Each participant will be match-paired to either HIIT or MCEET group based on their time to complete a mile run. There will be rank from 1 to 40, where number one will be assigned randomly to one group while two goes to the other group. Then, number three goes to the second group and fourth is assigned to the first group. Alternating patterns will be continued thereafter.|

Experimental: High Intensity Interval Training
six 20 second bouts of high intensity interval exercise (HIIT) separated by 2 minutes of active recovery with 3 minutes and warm up and cool down on the treadmill, three times per week for five weeks
The participant will perform HIIT where they will warm up for 3 minutes at 30% maximum heart rate (MHR), followed by 20 seconds of high intensity interval exercise at an all out intensity separated by 2 minutes of active recovery at 30% MHR. The interval will be repeated six times. Once completing all six intervals, participants will cool down for 3 minutes. This training program will be performed three times per week for five weeks.
14 minutes of Moderate Endurance Training with 3 minutes and warm up and cool down on the treadmill, three times per week for five weeks
The participant will perform MCEET, where they will warm up for 3 minutes at 30% maximum heart rate (MHR), followed by 14 minutes of moderate, continuous endurance exercise at 70% MHR. Participants will cool down for 3 minutes. This training program will be performed three times per week for five weeks.
- Program Adherence [ Time Frame: 5 weeks ]Physical Activity Enjoyment Scale assess levels of exercise enjoyment based on 18 questions on a 1 to 7 Likert Scale
- Program Adherence [ Time Frame: 5 weeks ]Exercise Adherence Rating Scale measures adherence to prescribed exercise program based on 6 questions on a 0 to 4 Likert Scale
- Body Composition [ Time Frame: 5 weeks ]A whole body densitometry (BodPod) measures body mass, fat mass and non-fat mass to determine body density which then gives body composition
- Endurance Capacity [ Time Frame: 5 weeks ]A mile run performance is an indication for a relative VO2 max.
