Physical education course is compulsory in higher education system of Iran. The curriculum focuses on physical fitness tests and student marks are apparently based on them. Students are dissatisfied with marking system and think it is unfair and biased. This destroys incentive and reduces the probability of a student''s engaging in physical activity. This study aimed to modify the evaluation system of the course. During three subsequent semesters all participants were tested and marked by a new psychomotor test battery accompanied by new standards. The study included the whole population of 2651 female and 992 male subjects (age 18-24 years). Tests were administered by the same standards، but different administrators in every semester. Test Battery included Stork stand test، Sit-ups، 30 meter sprint، Sargent vertical jump، Sit and reach، Pull-ups، T-test، Trunk lift، Phantom chair، and PACER. Demographic data included age، weight، stature، and BMI. A new set of norms and standards were set for evaluation of the course. Distribution line-charts of new marks were compared to older ones. For females، distribution of marks became closer to ideals، whilst for boys it did not take place. Standardization of fitness testing and scoring neither resolved abnormal distribution of final marks nor eradicated dissatisfaction of students with their marks. It is likely that instructors had alternated final marks based on their subjective understanding of achievements of students in affective and cognitive domains. It seems likely if standardization of scores for affective and cognitive achievements is added to standardization of fitness scores، the marking system might improve.

Background: flatfoot is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries Aim: to the purpose of this study was to compare some motor-physical factors, lower extremity performance and stability index in male adolescents 10-12 having structural flat foot with and without insole. Materials and Methods: Subjects who utilized medical insoles for four to six months were selected in access from technical orthopedic in Karaj. After parents got aware of the purpose and conditions participating in research, their height and weight were measured. In the first day, they were assessed by motor-physical factors test (agility, speed, endurance), lower extremity performance (one-leg jump, cross jump, maximum distance access, walking six meters) and stability index wearing insole and on the next day without wearing insole. To analyze data, paired t-test was utilized. Wilcoxson was used respectively for parametric and non-parametric data. Results : According to the paired t-test a significant difference was observed in the 6-meter timed test. Mean difference was slower in wearing insole compared to not wearing insole. Moreover, stability index results showed more stability when not wearing insole which eyes were closed to significant. Conclusion: According to the results, wearing insole in individuals with flat foot, could slow down the walking speed. However, wearing insole may improve stability index when visual input is not in access.

Background: The physical fitness is essential for wrestlers to perform successfully. The Tabata Protocol can be appropriate to develop these physical qualities.Aim: This study aims to investigate the effects of high-intensity interval training using “Tabata  protocol” on the physical fitness of teenage wrestlers.Material and Methods: 16 participants were randomly assigned to two groups of Tabata training (n=8) and the control group (n=8). All mentioned variables were measured before and after 4 weeks of the intervention. Tabata training group performed Tabata protocol in 2- 3 sets of 8 exercises with 20 sec of training and 10 sec of rest. The control group kept up their normal training routine during the same time. Physical fitness components were measured. The collected data were statistically analyzed by an independent t-test at a significance level of P>0.05.Results: Wrestlers in both groups significantly increased physical fitness components except flexibility (P<0.05). Tabata training was significantly more efficient in endurance of core muscle (P= 0.019, ES= 0.490) and upper body strength (P= 0.001, ES= 0.490) than control group (P<0.05). Also, results showed that for leg explosive power, only Tabata training had a positive effect (P= 0.026, ES=0.541).Conclusions: Our results suggest that wrestlers after Tabata protocol interventions can obtain better physical fitness, and event time benefits with more efficient performance and time-efficient manner compared with control group.
