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

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.

Resistance training in the treatment of non-insulin-dependent diabetes mellitus. [2022]Aerobic endurance exercise has traditionally been advocated in the treatment of non-insulin-dependent diabetes mellitus (NIDDM). However, the effect of aerobic endurance exercise programs on long-term glycaemic control is small to moderate. The aim of the present study was to determine the effect of circuit resistance training on long-term glycaemic control (HbA1c) and to examine the potential association between muscle size and glycaemic control in NIDDM subjects. Eight NIDDM subjects participated in a 3 month individualized progressive resistance training program (moderate intensity, high-volume) twice a week with measurements of HbA1c, lipids, blood pressure, VO2max and thigh muscle cross-sectional area. There was a significant improvement in HbA1c (8.8% - 8.2%; p
Resistance Exercise Intensity is Correlated with Attenuation of HbA1c and Insulin in Patients with Type 2 Diabetes: A Systematic Review and Meta-Analysis. [2022]We investigated the influence of resistance exercise (RE) with different intensities on HbA1c, insulin and blood glucose levels in patients with type 2 diabetes (T2D). Diabetes trials that compared RE group with a control were included in meta-analysis. Exercise intensities were categorized into low-to-moderate-intensity and high-intensity subgroups. Intensity effect on glycemic control was determined by meta-regression analysis, and risk-of-bias was assessed using Cochrane Collaboration tool. 24 trials met the inclusion criteria, comprised of 962 patients of exercise (n = 491) and control (n = 471). Meta-regression analysis showed decreased HbA1c (p = 0.006) and insulin (p = 0.015) after RE was correlated with intensity. Subgroup analysis revealed decreased HbA1c was greater with high intensity (-0.61; 95% CI -0.90, -0.33) than low-to-moderate intensity (-0.23; 95% CI -0.41, -0.05). Insulin levels were significantly decreased only with high intensity (-4.60; 95% CI -7.53, -1.67), not with low-to-moderate intensity (0.07; 95% CI -3.28, 3.42). Notably, values between the subgroups were statistically significant for both HbA1c (p = 0.03) and insulin (p = 0.04), indicative of profound benefits of high-intensity RE. Pooled outcomes of 15 trials showed only a decreased trend in blood glucose with RE (p = 0.09), and this tendency was not associated with intensity. Our meta-analysis provides additional evidence that high-intensity RE has greater beneficial effects than low-to-moderate-intensity in attenuation of HbA1c and insulin in T2D patients.
Feasibility and preliminary efficacy of high intensity interval training in type 2 diabetes. [2022]To compare the feasibility of high intensity interval exercise (HI-IE) versus moderate intensity continuous exercise (MI-CE) in patients with type 2 diabetes (T2D), and to investigate the preliminary efficacy of HI-IE and MI-CE for improving glycated hemoglobin A1c (HbA1c) and body composition.
High-intensity exercise training for the prevention of type 2 diabetes mellitus. [2014]Aerobic exercise training and diet are recommended for the primary prevention of type 2 diabetes mellitus and cardiovascular disease. The American Diabetes Association (ADA) recommends that adults with prediabetes engage in ≥ 150 minutes per week of moderate activity and target a 7% weight loss. However, traditional moderate-intensity (MI) exercise training programs are often difficult to sustain for prediabetic adults; a commonly cited barrier to physical activity in this population is the "lack of time" to exercise. When matched for total energy expenditure, high-intensity (HI) exercise training has a lower overall time commitment compared with traditional low-intensity (LI) or MI exercise training. Several recent studies comparing HI exercise training with LI and MI exercise training reported that HI exercise training improves skeletal muscle metabolic control and cardiovascular function in a comparable and/or superior way relative to LI and MI exercise training. Although patients can accrue all exercise benefits by performing LI or MI activities such as walking, HI activities represent a time-efficient alternative to meeting physical activity guidelines. High-intensity exercise training is a potent tool for improving cardiometabolic risk for prediabetic patients with limited time and may be prescribed when appropriate.

Effects of high-intensity circuit training, low-intensity circuit training and endurance training on blood pressure and lipoproteins in middle-aged overweight men. [2022]The aim of this study was to determine the physiological effects of an high-intensity circuit training (HICT) on several cardiovascular disease risk factors in healthy, overweight middle-aged subjects, and to compare the effects of HICT to traditional endurance training (ET) and low-intensity circuit training (LICT).
Metabolic effects of two high-intensity circuit training protocols: Does sequence matter? [2022]Label="BACKGROUND/OBJECTIVE" NlmCategory="OBJECTIVE">The integration of high-intensity interval training (HIIT) and circuit weight training (CWT) is seamless and practical for meeting recommended exercise guidelines. The purpose of this study was to determine the ideal combination of HIIT and CWT to elicit desired acute cardiorespiratory and metabolic responses in variables such as energy expenditure (EE), oxygen consumption (VO2), heart rate (HR), blood lactate (BLa-), excess post-exercise oxygen consumption (EPOC), rating of perceived exertion (RPE), and enjoyment.
The effect of chronic high-intensity interval training programs on glycaemic control, aerobic resistance, and body composition in type 2 diabetic patients: a meta-analysis. [2023]Type 2 diabetes is an increasing health problem worldwide. HIIT has been proposed as an exercise alternative to be part of integral type 2 diabetes treatment.
Resistance training improves the metabolic profile in individuals with type 2 diabetes. [2022]Aerobic endurance exercise has traditionally been advocated in the treatment of type 2 diabetes, while the potential role of resistance training has often been overlooked. The aim of the present study was to determine the effect of circuit-type resistance training on blood pressure, lipids and long-term glycaemic control (HbAlc) in type 2 diabetic subjects. Thirty-eight type 2 diabetic subjects were enrolled in the study; 18 participated in a 5-month individualized progressive resistance training programme (moderate intensity, high volume) twice a week, while the remaining 20 served as controls. The exercise group showed improvements in total cholesterol (6.0 +/- .3 vs 5.3 +/- .3 mM; P
Effects on training and detraining on physical function, control of diabetes and anthropometrics in type 2 diabetes; a randomized controlled trial. [2014]The purpose of this study was to investigate the effect of circuit exercise training and detraining, which is defined by termination of training without additional physical activities, in type 2 diabetic patients. Elderly with type 2 diabetes were divided into a group that exercised for 1 h three times a week for 12 weeks, followed by detraining for 8 weeks, or into a control group. Muscular strength, endurance, flexibility, agility, balance, body mass index (BMI), glycosylated hemoglobin (HbA1c), and blood lipid profile were measured. Of the 98 diabetic participants who joined this study, 37 patients completed the program (exercise group = 24, control group = 13). After training, muscular strength, flexibility, balance, agility, and endurance in the training group were significantly higher than at baseline and compared to the control group. HbA1c levels decreased in the training group. There was no significant improvement in BMI and blood lipid profile in either group. Flexibility and agility in the training group declined significantly after detraining. In spite of this decline, flexibility and agility were significantly higher compared to the baseline and to the control group. In type 2 diabetic patients, circuit training had a beneficial effect on the indices of physical function and glucose metabolism. Training resulted in good improvement; and during detraining, the effect of exercise training was maintained except in some parameters.
