The aim of the first year of this three-year plan is to analyze and compare the muscle quality of lower limb muscle (microcirculation, muscle performance and mechanical characteristics) and maximal aerobic exercise capacity in treadmill exercise tests for diabetic and non-diabetic cases. The hypotheses are:1) the muscle quality of lower limb muscle and maximal aerobic exercise capacity are different between participate with diabetic and non-diabetic, 2) the effect of the three-month aerobic exercise intervention or home exercise on the characteristics of the muscle quality are different , and 3) intrinsic factors (such as age, BMI, and HDL) and characteristics of specific FTO genes are influenced the training outcomes.
Name: supervised aerobic exercise or home-based aerobic exercise
Description: elastography was used, units on kPa
