چکیده:
Due to the increase in ob 's world, encouraging the individualsto do appropriate and a ying sports programs with different structures are if great im udy the effect of 30 minutes interval short courses of running an intensity of 60-75% of heart rate reserve (HRR) for 6 wee capacity (Vo2max) in untrained girl university students. Twenty six untrained girl university students aged 19 to 23 years old with a percentage of body fat (PBF) of more than 30 and a Vo2max of less than 40 ml/kg/min were randomly selected and into divided into two groups including training group (n=16) and the control (n=10). Weight, body mass index (BMI), percentage of body fat (BF%), lean body mass (LBM), and maximal oxygen uptake (VO2max) were measured as indicators of health before and after six weeks of trial. Findings of the present study showed that 6 weeks of interval running improved body composition and aerobic capacity of untrained girls. This means that there was a significant decrease in PBF, weight, and BMI of untrained girls. In addition, maximal oxygen consumption showed a significant increase (p≤0.05), while no significant change was observed in lean body mass. Findings of the present study indicate the importance of combining the short courses of work and rest for 30 min in a day. The present study merely discuss the effective role of interval short course training in stimulating and changing physiological adaptations and consequently improving the performance of cardiovascular system and body composition in untrained girls.

ow activity; obesity; interval training; aerobic capacity; percentage of body fat;body mass index INTRODUCTION Tremendous advances in technology and mechanical lifestyle of people in this century have made many works easier from one hand and caused a significant decrease in physical activity level, lifestyle change, inactivity and low mobility of individuals, and obesity (1).
No significant change was variables for the control present study showed erval running improved and aerobic fitness of means that, as a result interval running, a in weight, body mass ous fat and a significant increase in maximal oxygen consumption of the subjects were observed.
de Souza e Silva et al (2009) showed that 50 minutes of exercise (رجوع شود به تصویر صفحه) (2×20 min of exercise and 10 min rest) for 12 weeks and 5 days per week caused significant increase in maximal oxygen consumption and a significant decrease in percentage of body fat and waist circumference of the subjects which is consistent with the results of the present study (13).
(3, 14, 24-30) On the other hand, the results of the present study are inconsistent with the findings of Osei- Tutu et al (2005), who studied the effect of 8 weeks of short-term interval exercise (3 ten- hanges of percentage of not achieve significant ossible reason can be sidering the training and colleagues used fewer replicates (3 ten- ctivity periods) which uitable to stimulate tions for fat oxidation."
