Sequences of Aerobic and Resistance Exercise in Training and Their Effects on Cardio-metabolic Functions Among Type 2 Diabetes Patients - a Randomized Study
In Brief
A clinical study evaluating AR group: aerobic training before resistance training and RA group: resistance exercise before aerobic exercise for Type 2 Diabetes. Completed, enrolled 56 participants across 1 site.
Detailed Summary
Aerobic exercise and resistance exercise are two types of exercise commonly used in physical conditioning. Compared to aerobic exercise, a combination of aerobic and resistance exercise has been linked to a greater reduction in hemoglobin A1c (HbA1c) among patients with type 2 diabetes (T2D). However, it is not clear that in a concurrent aerobic-resistance training session, whether the orders of the two types of exercise could act differently in glucose metabolism. This randomized trial aims to investigate the effect of the sequence of exercise modalities (aerobic-resistance vs resistance-aerobic in a training session) on glycemic control among T2D patients following an 8-wk intervention period.
Study Details
Timeline
Interventions
Exercise are performed 3 times/wk for 8 wks. Aerobic training sessions are performed using cycle ergometers. Riding speed is 55-60 rotations/min, at an intensity between 50%-75% of heart rate reserve (HRR). Real-time heart rate monitors are worn by each participant during the session. Aerobic training session lasts for 30 minutes, with an additional 5-minute warm-up and 5-min relaxation training before and after the session, respectively. Participants perform resistance exercise on a set of strength training equipment. Load of resistance exercise is between 60-80% of repetition maximum (RM) in each set of exercise. Six different groups of resistance exercise (involving contractions and relaxations of biceps, triceps, pectoralis major, latissimus dorsi, quadriceps, and hamstrings) are conducted, with 6 sets of 10 repeated tasks in each group. Participants are instructed to finish each set of exercise task within 60 seconds. Between each two sets, there are 60 s of rest time.

Riding speed is 55-60 rotations/min, at an intensity between 50%-75% of heart rate reserve. Real-time heart rate monitors are worn during the entire session. Each aerobic training session lasts for 30 minutes, with an 5-minute relaxation training after the session.
