Abstract:The aim of this study was to compare the effects of two types of high intensity interval training (HIIT) on body mass and physiological indexes in inactive female students. 27 inactive female students (mean age 24.81 ± 0.66 yr, height 162.09 ± 0.67 cm, weight 59.41 ± 0.33 kg) were voluntarily selected and randomly assigned to three groups (each group = 9 subjects) of high intensity interval training (type 1), high intensity interval training (type 2) and control. HIIT (type 1) (8 seconds of sprint running and 12 seconds of active recovery) was performed for 4 weeks, 3 sessions per week, 6-9 min. per session with above 90% maxHR. HIIT (type 2) (40-m shuttle run test with maximum speed) was performed with above 90% max HR while the control group did not participate in any training. Data analysis with dependent t test showed that HIIT (type 1) and HIIT (type 2) significantly increased VO 2max while they decreased fat percentage and BMI. The intergroup data were analyzed by one-way ANOVA at P < 0.05. The results showed a significant difference among HIIT (type 1), HIIT (type 2) and control groups in VO 2max , BMI and fat percentage.

In this study, emotional intelligence, which is the ability to understand the excitement and emotion, was evaluated in Iranian elite wrestlers (with the mean age 19.40±5.5years) to determine its relationship with sports injuries. For this purpose, 90 wrestlers, who had participated in Country Championships and who had been invited to Iranian national team in 2012, participated in this research. For data collection, profile sheets, the Schulte Self Report Emotional Intelligence Test, sports injury reports and interviews with athletes and team physicians in addition to available medical records were used. Based on the wrestlers' injury reports, there was an average of 12 injuries in 2012. The results showed significant negative relationships between the ability of wrestlers to regulate emotions (p=-0.309), their ability to use emotions (p=-0.313), their ability to assess their emotions (p=-0.582), their ability to generally regulate their emotions (p=-0.445) with the number of sports injuries. Also, only the ability to assess the emotions could predict the probability of injuries in wrestlers, that is, the wrestlers who had high ability to regulate their emotions suffered from lower injuries. The significant relationship between the components of emotional intelligence and the number of sports injuries showed that the athletes who had lower ability to regulate their emotional intelligence might put themselves more in risky situations and consequently more injuries. Coaches and officials are recommended to identify these athletes and to improve their emotional intelligence to reduce the probability of their sports injuries
