Overview
Brief Summary
The aim of the study is to determine the physiological evidence of how muscular and cerebral oxygenation changes link to fatigue, physical, and cognitive performance after moderate-intensity exercise in sedentary older adults with type 2 diabetes.
Detailed Description
This is an experimental design. One intervention group will do exercise for 2 months and be measured twice, at baseline, and after 2 months. The other 2 control groups will be assessed just once without exercise intervention. Our primary objective is to clarify physiological evidence of how muscular and cerebral oxygenation changes in sedentary older adults with diabetes after low-to-moderate intensity exercise. The secondary objective is to determine fatigue, physical, cognitive performance changes, blood glucose level among sedentary older adults with diabetes after low-to-moderate intensity exercise.

Outcomes
Primary Outcomes
normalized ∆SmO2 rate
Time Frame: measure twice, at baseline and after 2 months
a parameter of muscular oxygenation to indicate the match or mismatch between oxygen supply and oxygen demand during the physical stimulus.
recovery time
Time Frame: measure twice, at baseline and after 2 months
a parameter of muscular oxygenation, time taken in seconds after the exercise to back to the beginning oxygenation level.
Oxyhemoglobin differences
Time Frame: measure twice, at baseline and after 2 months
a parameter of cerebral oxygenation, the difference of the oxyhemoglobin in mL per gram before and after the cognitive tests.
Resting SmO2
Time Frame: measure twice, at baseline and after 2 months
a parameter of muscular oxygenation, the average oxygenation level in % while sitting still for 3 minutes before doing physical performance tests.
Secondary Outcomes
- Fatigue(measure twice, at baseline and after 2 months)
- Mini-cog test(measure twice, at baseline and after 2 months)
- Trail Making Test(measure twice, at baseline and after 2 months)
- Timed Up and Go test score in seconds(measure twice, at baseline and after 2 months)
- Bilateral Heel Raise test(measure twice, at baseline and after 2 months)
