the purpose of this study was the comparison effect implementation methods physical activity outside of class on the physical fitness of 15 y. boy students. method of study was quasi experimental and statitical population of that includes all of the 15 y. boy students of  maraghe city(n=2865). sample of study was 80 pepole who were selected of sample available and then randomly in four groups of 20 people called as experimental group 1, the method on based students self-supervision, experimental group 2, the method on based parentals supervision, experimental group 3, the method on based physical education teachers supervision and controll group that were homogenous. at first a pretest was done from the four groups by pull up test, sit and rich test, sit up test, 540 meter running test. implementation methods physical activity outside of class were done on groups for 8 weeks and then a post test was done from four groups. for statistical analysis of multivariate analysis of variance was used for comparison mean between groups.The results showed that the method of enforcement activity outside of class fitness factors of boy students, there are significant differences ( p≤0/05).however, The results showed that the method on based physical education teachers supervision had a  more impact on physical  fitness  related to health.

The current research aims to compare the effect of basic gymnastic exercises in environments with different colors, on static and dynamic balance. Participants were 40 female students ranging in age from 8 to 10 years, who were classified into three groups: "exercise in the environment with warm colors", "exercise in the environment with cool colors" and "exercise in the environment with compound colors". A pre-test of balance was given to each group in its colored environment. Static and dynamic balance were assessed using the balance subscale of bruininks-oseretsky test of motor proficiency. Then the groups have performed gymnastic exercises in colored environments for 24 sessions, and after 8 weeks, they took the post-test in the same environment. The transfer test was performed in the environment with a neutral color, 48 hours after the post-test. Data were analyzed using one-way ANOVA and ANCOVA tests. The findings showed that the color of the environment had had no effects on the learning and retention of static and dynamic balance.it seems that, the color of learning environment related to type of motor skill.
