Stimulating the hormones and enzymes involved in the lipolysis, resistive exercises can increase lipolysis. The aim of this study was to examine the effect of circular resistive exercises before exhausting running on treadmill on fat and carbohydrate oxidation and energy expenditure in overweight and obese girls.

Ten overweight and obese girls (weight range: 78.02 to 10.18 kg) performed two types of exercises: 1) performing circular resistive exercises before running on treadmill, 2) just running on treadmill without any circular resistive exercises. Running on treadmill was performed at the intensity of 75% of the maximum heart rate until they were exhausted, and the circular resistive exercises consisted of five stations, each with three rounds at 55% of 1-RM (1-Repetition Maximum). The respiratory gases of the participants were measured by a gas analyzer system for 30 minutes in the baseline and while running on the treadmill until exhaustion. The collected data was analyzed using multivariate analysis of variance (MANOVA) (α = 0.05).

It was found that fat metabolism during the activity in the first group (performing circular resistive exercises before running on treadmill) were significantly higher than the second group (just running on the treadmill). Energy expenditure and carbohydrate metabolism were not reported to be significantly different between the two groups of the study.

Overweight and obese girls can use circular resistive exercises before running on a treadmill in order to increase their fat oxidation and reduce their body fat percentage.

The purpose of this study was to compare effects of three combined aerobic-resistance exercise training protocols with different intensities on adiponectin, retinol binding protein4 and lipid profile in men with type 2diabetes. 43male patients with type2 diabetes were randomly divided into 4groups (three combined aerobic-resistance exercise training groups 1 (Age 47.3±9.0, Weight 77.1±9.1, BMI 26.6±3/5), 2 (Age 45.6±8.3, Weight 80.6±8.7, BMI 26.9±1.8), 3 (Age 47.0±5.9, Weight 82.9±11.7, BMI 28.0±2.9) and control (Age 46.1±9.2, Weight 84.4±10.3, BMI 28.2±2.4)). Training groups performed combined aerobic-resistance exercises for 12 weeks, 3 times a week with given intensities )group 1: resistance 50-60% one repetition maximum- aerobic 70-80% maximum heart rate, group 2: resistance 60-70% one repetition maximum- aerobic 60-70% maximum heart rate and group 3: resistance 70-80% one repetition maximum- aerobic 50-60% maximum heart rate). The blood sampling to determine the levels of adiponectin, retinol binding protein 4 and lipid profile before and after 12weeks, were conducted. Data were analyzed using analysis of covariance. Retinol binding protein 4 levels significantly decreased in 2 and 3 combined training groups compared with control group (P

The purpose of this study was to compare effects of three combined aerobic-resistance exercise training protocols with different intensities on metabolic control and Visfatin levels in men with type 2 diabetes.
43 male patients with type 2 diabetes were randomly divided into 4 groups (three combined aerobic-resistance exercise training groups 1, 2, 3 and control). Training groups performed combined aerobic-resistance exercises for 12weeks, 3 times a week with given intensities )group 1:resistance 50-60% one repetition maximum- aerobic 70-80%maximum heart rate, group 2:resistance 60-70% one repetition maximum- aerobic 60-70% maximum heart rate and group 3:resistance 70-80% one repetition maximum- aerobic 50-60% maximum heart rate). Blood sampling to determine the levels of Visfatin, insulin, HbA1c, fasting glucose before and after 12weeks, were conducted.
Visfatin levels and HbA1c in all training groups and fasting glucose in 2 combined training groups significantly decreased compared with control group (P 12 weeks of combined aerobic-resistance exercise training protocols with were executed intensities through decreasing Visfatin and HbA1c levels and improving aerobic capacity could be helpful in patient with type 2diabetes. In addition to the above benefits, combined exercise training protocols of with intensity of 60-70% maximum heart rate–intensity 60-70% repetition maximum due to reducing fasting blood glucose could give greater benefits to patients.

The purpose of this study was to determine the effects of combined aerobic-resistance training on lipid profile and liver enzymes in patients with non-alcoholic fatty liver disease under diet. 19 male patients (age: 38.1±8.2 years and BMI of 28.1±3.8 Kg/m2) were randomly divided into two groups of diet and diet plus exercise intervention. Training program included combination of aerobic (50-70 Percent of HRR) and resistance training (50-70 percent of 1RM), eight weeks and three sessions per week. In order to designing dietary regimen, alleviate 400 to 500 kcal/day from total daily calorie intake. Before and after intervention, blood taking, body composition, maximal oxygen consumption, and muscular strength assessment performed. Data were analyzed using dependent and Independent-Samples T test on gain scores, employing the SPSS 18 statistical package program (α≤0.05). The results indicated significant improvement in maximum oxygen uptake (P= 0.0001), and reduction in body composition indexes, TC (P= 0.0001), TG (P= 0.01), LDL (P= 0.004) and TC/HDL (P= 0.0001) in both diet and combined exercise group. In diet group, a considerable improvement was observed in weight (P= 0.01), body mass index (P= 0.01), waist circumference (P= 0.004), waist to hip ratio (P= 0.04), maximum oxygen uptake (P= 0.0001), TC (P= 0.01), LDL (P= 0.005) and TC/HDL (P= 0.003). But between group differences were not significant. This study showed that eight weeks of diet alone and combined with diet have no significant effect on liver enzymes in non alcoholic fatty liver patients, but induce increase in maximal oxygen consumption and improvement in lipid profile in patients with non alcoholic fatty liver. However, there is not significant difference between two groups. Insufficient period of intervention (diet and exercise), frequency and intensity of training may be the possible causes of ineffectiveness of exercise and diet on above-mentioned variables.
