About this study

Official title: Effects of Different Aerobic-to-Resistance Training Time Ratios in Adults Aged 50 Years and Older With Prediabetes: A Randomized Controlled Trial

The goal of this clinical trial is to evaluate how different time ratios of aerobic and resistance training affect blood glucose levels and physical health in adults aged 50 years and older with prediabetes. Researchers will compare three combined exercise programs with aerobic-to-resistance training time ratios of 3:1, 1:1, and 1:3 with a health education control group.

Participants in the exercise groups will take part in supervised training three times per week for 12 weeks. Each session will include approximately 60 minutes of aerobic and resistance exercise, with the amount of time spent on each type of exercise differing according to the assigned group. Participants will complete health assessments before and after the 12-week intervention. The main outcome of interest is glycated hemoglobin (HbA1c), which reflects average blood glucose levels over the previous 2 to 3 months. Participants in the control group will receive standardized health education and will not take part in the study-provided structured exercise program during the 12-week intervention period.

Read the detailed description

Prediabetes is a high-risk metabolic state associated with an increased likelihood of developing type 2 diabetes and other cardiometabolic complications. Both aerobic and resistance exercise can improve glucose regulation and metabolic health, but there is limited evidence regarding how the relative amounts of aerobic and resistance training should be combined when the overall training duration is kept similar. This study is designed to compare different aerobic-to-resistance training time ratios while maintaining a broadly comparable overall exercise duration across the exercise groups.

This is a prospective, four-arm, parallel-group randomized controlled trial. A total of 212 adults aged 50 years and older with prediabetes are planned to be randomly assigned in a 1:1:1:1 ratio to one of three combined aerobic and resistance training groups or to a health education control group. The three exercise groups will use aerobic-to-resistance training time ratios of 3:1, 1:1, and 1:3.

Participants assigned to the exercise groups will complete supervised training three times per week for 12 weeks. Each session will include approximately 60 minutes of main exercise training. The 3:1 group will complete approximately 45 minutes of aerobic exercise and 15 minutes of resistance training, the 1:1 group will complete approximately 30 minutes of each, and the 1:3 group will complete approximately 15 minutes of aerobic exercise and 45 minutes of resistance training. Aerobic training will consist of a standardized low-impact aerobic exercise routine. Resistance training will include standardized exercises targeting major muscle groups. Exercise intensity, resistance, and exercise difficulty will be progressively adjusted according to predefined training principles, safety considerations, and individual tolerance.

All study groups will receive standardized general health education. The control group will continue usual medical and community care and will not receive the study-provided structured aerobic and resistance exercise program during the 12-week intervention period.

Randomization will occur after completion of baseline assessments and confirmation of eligibility. Because of the nature of the exercise intervention, participants and exercise instructors cannot be masked to group assignment. Laboratory samples will be identified using coded study numbers without information on intervention assignment.

Study assessments will be conducted at baseline and after the 12-week intervention, with an additional follow-up planned approximately 12 weeks after completion of the intervention to explore the maintenance of selected effects. Assessments include measures of glucose regulation, body composition, physical performance, muscle strength, functional exercise capacity, physical activity, and selected metabolic measures. Continuous glucose monitoring and some additional mechanistic assessments will be conducted in prespecified exploratory components of the study.

    Participants will complete 12 weeks of supervised combined aerobic and resistance training, three sessions per week. Each session will include approximately 60 minutes of main training, consisting of approximately 30 minutes of a standardized low-impact aerobic exercise routine and 30 minutes of resistance training. Training intensity and exercise difficulty will be progressively adjusted according to predefined safety criteria and individual tolerance.

Each session will include approximately 60 minutes of main training, consisting of approximately 15 minutes of a standardized low-impact aerobic exercise routine and 45 minutes of resistance training. Training intensity and exercise difficulty will be progressively adjusted according to predefined safety criteria and individual tolerance.
