RESUMEN
Background: There are evidences that obesity is influenced by physical activity, but the daily nutrition can modify its effect. According to this, the aim of present study was to evaluate the effect of aerobic training on body compositions indices in male rats fed with high fat diet
Materials and methods: In an experimental trial, 16 Wistar male rats were divided randomly to two groups, including aerobic training + high fat diet group and high fat diet without any aerobic training group. High fat diet was composed of 40% fat, 13% protein and 47% carbohydrate. The training protocol was in progressive form, thus exercise intensity was increased every week. The aerobic training included running at speed of 20 m/min in 1st week and reached to 25 m/min in 12th weeks. Waist circumference, chest circumference, Lee index were measured in first week, end of batten level, end of 6th and 12th weeks
Results: Intake of high fat diet induced significant increase in the body weight, body mass index [BMI], Lee marker and waist to chest ratio [P=0.001]. The aerobic training didn't have any significant effect on the anthropometric markers of obesity
Conclusion: The results showed the aerobic training couldn't decrease body weight, and high fat diet induced negative impression. Therefore, it is recommended that aerobic training alone isn't effective solution for reducing the weight gain caused by excess calorie intake
RESUMEN
Background and Aim: The present study aimed at investigating the effect of a 12-week aerobic water exercise and atorvastatin on of Atrial Natriuretic Peptide [ANP] and Brain Natriuretic Peptide [BNP] changes in older men with cardiovascular diseases
Materials and Methods: In the current study, 40 patients with cardiovascular disease, aged 50-65yrs, who were volunteers for the research were divided in to four equal groups including1.exercise, 2.exercise plus atorvastatin, 3.atorvastatin, and 4.control. Then, blood was taken before and after the interventions. Groups 1 and 2 performed the specific water aerobic exercise 3 times a week for 12 weeks. Group 3 took 20mg of atorvastatin daily under a physician Water aerobic exercise lasted 12 weeks, 3 periods a week, with intensity of 55-60% of heart-beat. Every week, due to overtax principle, 3.5 minutes was added to exercise period. In order to determine the difference between pre-test and post-test, dependent T was applied. Intergroup difference was determined through ANOVA using Tukey for post-test; [P
Results: ANOVA application revealed that mean of functional variables in pre-test compared to that of posttest was significantly different. Mean post-test of BNP in the four groups exercise, atorvastatin, exercise plus atorvastatin and control was P= 0.001, P=0.002, P=0.000, respectively. But mean post-test of ANP in the above mentioned groups was P=0.022, P=0.001, P=0.000, respectively
Conclusion: Aerobic exercises together with daily taking of atorvastatin can have significant effects on decreasing natriuretic peptides and CVDs
