Abstract: (2489 Views)
Background: Type 2 diabetes is one of the chronic metabolic diseases that because of the high incidence and burden of this disease it was introduced as one of the public health problems (1). Complications of diabetes are related to problem in controlling the glycemic level in type 2 diabetic patients which leads to increased mortality and morbidity in these patients (5,6). Quality of lifestyle is one of the main principles of diabetes treatment (7). The results of longitudinal research indicate that exercise is one of the effective therapeutic interventions to treat, prevent and reduce the complications of metabolic diseases (8). One of the methods of aerobic training is Body pump. Although this sport does not have much history, but it has quickly been able to gain a lot of popularity in the must countries of the world, however, not much study has been done about it in Iran. Body pump is a program to improve physical fitness that includes about 60 minutes of training in the classroom with training weights based on predetermined tracks in which various sports movements are preformed with the rhythm of the music (9). In general, Body pump training class is a typical resistance training program with a large number of repetitions that is include low and medium intensities with focuses on endurance (10). On the other hand, one of the items that is in compliance with exercise is intensity, which is impact on the adaptation and obtained from exercise in healthy people and patients (12). It could be considered that the intensity of exercise can be one of the factors affecting metabolic adaptations in diabetic patients. So far a specific study on the role of intensity in Body pump exercises was confirmed as one of the new styles of rhythmic exercises in controlling blood sugar in patients, therefore, the aim of this study is to compare the effect of eight weeks of exercise with two different intensities on controlling the glycemic level in obese women with type 2 diabetes.
Methods: In the present quasi-experimental study, 30 women with type 2 diabetes from Ahvaz Diabetes Clinic were selected by random sampling method and randomly divided into 3 groups of 10, including two groups. Intervention Body pump exercises were divided into moderate and high intensities and controls. The training program was performed for 24 sessions for eight weeks and in each session on a daily basis (3 day a weeks), and each training session including 60-90 minutes of Body pump exercise which performed at 9-10 am. In the first group exercise was performed with 55-60 percent of maximum reserved heart rate (moderate intensity training) and in the second group training with 75-80 percent of maximum reserved heart rate (high intensity training). Fasting blood sampling was performed in two stage of pre-test (24 hours before the start of research interventions) and post-test (48 hours after the last training session) and fasting blood sugar levels, fasting insulin, insulin resistance and HbA1c were measured. The statistical analysis of information obtained from the subjects, dependent t-test was used to examine intragroup changes and statistical test of analysis of covariance and LSD post hoc test were used to examine intergroup changes. Statistical analysis was performed with SPSS software version 25 and was considered at a significate level (p≥0.05).
Results: The subgroup analysis showed the significant decrease in the level of fast blood sugar, fast insulin, resistance to insulin and HbA1c in both groups with medium intensities exercise (p=004; p=0.029; p=0.20; and p<0.001, respectively) and high intensities exercise (p=0.020; p<0.001; p=006; and p<0.001, respectively). No significant difference was observed in the control group with no exercise (p>0.05). To evaluate the effect of the intensity of the training on the variables of the study, significant difference was observed between changing in fast blood sugar (p=0.591), fast insulin (p=0.847), resistance to insulin (p=0.989) between both medium and high intensities training. However, HbA1c changes were significant and it was higher in the high intensities training group in comparison with medium intensities group (p=0.019).
Conclusion: According to the results, both intensities in Body pump training led to decrease in fast blood sugar, fast insulin, homeostatic model assessment of insulin resistance (HOMA-IR) and HbA1c in type 2 diabetic women. Based on previous results, medium (24, 23, 8) and high intensities training (25) led to control glycemic level in type 2 diabetic patients. To analysis the effect of the intensity of the training on variables, it was shown that there is no significant differences between the changes in the level of fast blood sugar, fast insulin and resistance to insulin in both Body pump with medium intensity and high intensity groups. However, changes in HbA1c as a blood sugar average index in Body pump with high intensity group showed a significant difference in comparison with medium intensity group. This results showed the positive effects of training as a variable in control of hypoglycemic level in type 2 diabetic women. According to this result in clinical condition, controlling the blood sugar level and HbA1c level can prevent the complication and mortality and morbidity in type 2 diabetic patients and the Body pump training had a great effect on health promotion and decreasing the diabetic complication. High concentration of HbA1c is related to diabetic neuropathy, diabetic retinopathy and nephropathy in long time (28). In the present study 6.3 % HbA1c and 23.3 % resistance to insulin were decreased in Body pump with medium intensity group. Also, in Body pump with high intensity group, 12.4 % HbA1c and 24.7 % insulin resistance were decreased. It was reported that 1 % decrease in HbA1c is related to 14 % decrease in acute myocardial infraction and 21 % decrease in mortality (29). Based on twice more intensity in high intensity Body pump training group in comparison with medium group, it could be concluded that Body pump training with high intensity is more appropriate for reducing the microvascular and macrovascular complications. It is also recommended for diabetic type 2 patients that have no problems in practicing to do high intensity training.
