説明
Inclusion Criteria:
- overweight/obese Chinese man (25 kg/m2<BMI<32.5 kg/m2) aged between 21 and 60 years old; prediabetes, impaired glucose tolerance (mean 2-h blood glucose ≥7.8 and ≤11.1 mmol/l after a 75-g oral glucose challenge) or impaired fasting glucose (mean fasting blood glucose ≥6.1 mmol/l and ≤7.0 mmol/l and HbA1c levels between 5.7% and 6.4%).
Exclusion Criteria:
- any neurological, musculoskeletal or cardio respiratory condition, which would put them at risk during exercise or inhibit their ability to adapt to an exercise program; any subject participated in a regular vigorous exercise and/or diet program more than 2 times per week in the 3 months prior to recruitment; any subject who is taking medicine, especially antibiotics in the past week prior to study.

|
rate of non-responsiveness in the alleviation of insulin resistance to exercise intervention
時間枠:before and after 12 weeks after exercise training
|
Participants in the exercise arms are further classified into responders or non-responsders, depending on whether they could demonstrate a decrease of insulin resistance index (HOMA-IR) greater than 2-fold technical error, which is a threshold for true physiological adaptation.
HOMA-IR is calculated using homeostasis model assessment methods, defined as fasting insulin (μU/mL)×fasting glucose (mmol/L)/22.5.
