AbstractBackground and Purpose: 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.Materials and Methods: 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).Results: 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.Conclusion: 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.

Introduction:. The purpose of this study was to investigate the comparison of the effectiveness of two methods of operational-skills and combined exercises training of immunity systems in male firefighters. Materials and methods: 36 men firefighters were selected voluntarily. The participants of first experimental group were participated in one program of operational-skills training about eight weeks. This program was consisted of stair climb, equipment carry, victim rescue, ladder heel and raise, forcible entry, and hose drag. The treatment of the combined training program was included 15 minutes of aerobic running with 60 to 70 percent of maximum heart rate and five selected strength training for upper and lower parts of the body. Blood test was obtained with all the samples in fasted stated to determine the parameters of IL6, CD40 and cortisol before starting the training period and 48 hours after the last training sessions. The collected data were analyzed according to paired-samples t and analysis of variance with the significant level of P< 0.05. Results: The collected data revealed that the level of cortisol and serum IL6 were decreased significantly in two experimental groups in comparison with the control group. But the level of soluble CD40 had significantly differences in the first experimental group in contrast with the other groups, and there were no differences between two other groups. Conclusions: the results of this study suggested that, it is better the male firefighters use operational- skills training to strengthen the immune system and reduce risk factors in cardiovascular disease
