Trial Summary

What is the purpose of this trial?

This research study proposes to quantify the efficacy of the novel high intensity body-weight circuit (HIBC) training intervention on metabolic profile, body composition, and health related fitness exercise in middle aged persons with type-2 diabetes (T2DM). This research project is extremely relevant to public health, in that prevalence of T2DM continues to rise on a national and global scale, placing a heavy economic cost on both the healthcare industry and the individual patient in an age-dependent fashion. Results of this study may provide an effective and appealing alternative exercise intervention for cardiometabolic disease management in adults with T2DM, and have significant clinical and public health applications.

Will I have to stop taking my current medications?

The trial requires that participants are not on any medicinal treatment for their diabetes, so you would need to stop taking any diabetes medications before joining.

What data supports the effectiveness of the treatment High Intensity Circuit Training for Type 2 Diabetes?

Research shows that high-intensity exercise, including circuit training, can improve blood sugar control and reduce insulin levels in people with type 2 diabetes. This type of exercise is also time-efficient and can improve heart health and muscle function, making it a beneficial option for managing diabetes.12345

Is high-intensity circuit training safe for humans?

High-intensity circuit training (HICT) has been studied in various groups, including obese women and middle-aged men, and is generally considered safe when performed appropriately. It can improve physical fitness and cardiovascular health, but as with any exercise program, it's important to start at a suitable level and increase intensity gradually to avoid injury.34678

How does high-intensity circuit training differ from traditional exercise for type 2 diabetes?

High-intensity circuit training is unique because it combines short bursts of intense exercise with rest periods, making it a time-efficient alternative to traditional exercise. This approach can improve blood sugar control and physical fitness in people with type 2 diabetes, even with a lower overall time commitment compared to moderate-intensity exercise.3491011

Eligibility Criteria

This trial is for middle-aged individuals recently diagnosed with type-2 diabetes who haven't started any medicinal treatment and are not insulin-dependent. They should have an HbA1c level between 6% and 8%, no current exercise program, and must be willing to be randomly assigned to a workout group. Smokers or those with kidney, lung, heart diseases, past revascularization procedures, or cognitive dysfunction cannot participate.

Timeline

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Treatment

Participants undergo high intensity body-weight circuit (HIBC) training, starting with three sessions per week, increasing to four sessions per week after three weeks. Session duration starts at 5 minutes and increases by one minute each week, peaking at 10 minutes by the eighth week.

16 weeks
Sessions completed at home

Follow-up

Participants are monitored for changes in body composition, VO2max, glucose tolerance, and HbA1c levels after the intervention.

Interventions

  • high intensity body-weight circuit
  • traditional exercise intervention (TEI)
Trial Overview The study is testing the effectiveness of a new high intensity body-weight circuit (HIBC) training compared to traditional exercise interventions (TEI). It aims to see which one better improves metabolic profile, body composition, and fitness in people with type-2 diabetes.

Experimental Treatment
Group I: high intensity body-weight circuit (HIBC)Experimental Treatment1 Intervention
HIBC Exercise Protocol- circuit repetition and order is as follows: modified squats (10 repetitions), modified rows (5 repetitions), crunches (10), and modified push-ups (5). The exercise sessions will involve repeating a series of repetitions of each movement in sequence, and completing as many sequences as possible in good form in the time allotted for the exercise (initially, 5 minutes). Three sessions per week will be completed at home. After three weeks of training, participants will be asked to add a fourth session each week. Initially, the HIBC sessions will be five minutes long, and the duration of the sessions will increase by one minute each week as tolerated beginning in week four, peaking at 10-minutes per session (warm up not included in this timing) as early as the eighth week of training. Session duration will be capped at 10-minutes.

Findings from Research

A 3-month circuit resistance training program significantly improved long-term glycaemic control in subjects with non-insulin-dependent diabetes mellitus (NIDDM), as indicated by a reduction in HbA1c from 8.8% to 8.2%.
The study found a strong inverse correlation between muscle size (measured by thigh muscle cross-sectional area) and HbA1c levels, suggesting that increased muscle mass may enhance glycaemic control in NIDDM patients.
Resistance training in the treatment of non-insulin-dependent diabetes mellitus.Eriksson, J., Taimela, S., Eriksson, K., et al.[2022]
A meta-analysis of 24 trials involving 962 patients with type 2 diabetes showed that high-intensity resistance exercise significantly reduced HbA1c levels and insulin levels compared to low-to-moderate intensity exercise.
Specifically, high-intensity resistance exercise led to a greater decrease in HbA1c (-0.61) and insulin levels (-4.60), highlighting its effectiveness in improving glycemic control in patients with type 2 diabetes.
Resistance Exercise Intensity is Correlated with Attenuation of HbA1c and Insulin in Patients with Type 2 Diabetes: A Systematic Review and Meta-Analysis.Liu, Y., Ye, W., Chen, Q., et al.[2022]
A 12-week study involving 15 participants with type 2 diabetes showed that high intensity interval exercise (HI-IE) is as feasible as moderate intensity continuous exercise (MI-CE), with both groups maintaining high adherence rates of over 97%.
Both HI-IE and MI-CE effectively reduced total body fat and trunk fat, but neither intervention significantly changed glycated hemoglobin A1c (HbA1c) levels, indicating limited impact on blood sugar control in participants who were already well-managed.
