The aim of this research was to determine the effect of different training environments, type of skills and interactions on open and closed skills. The statistical  population was all students living in dormitories of Tehran University in the 88-89  academic year. The sample was 60 people selected based on convenience sampling methods among students who had no experience in badminton skills (Long Service and clear). Based on pre-test subjects were matched in six groups of ten persons (noncompetitive, competitive, and combined). All of six groups performed a practice in defined medium for 10 sessions and each session were performed 40 times. The long-service tests were used to measure open badminton skill and clear test was performed to measure closed skill. Test scores of subjects were computed based on the mean of ten hits score. Descriptive statistics were used to determine the mean and standard deviations and to test research hypothesis, a two-way analysis of variance (ANOVA) with repeated measures and independent t-test were utilized. The result of ANOVA showed that exercise in each of the training environment increased acquisition and retention of each skill, but the levels are different (p<0.05). Also, Factorial ANOVA showed that the skills and environments does not have meaningful effects on acquisition and retention of skills while each skill interacts significantly with the training environment (p<0.05). In addition, exercising each of the skills in the same environments had different levels of acquisition and retention.

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.

In this correlational study, physical activity of girls’ has been predicted using ecological approach. For this purpose, 374 girls aged 10-12 years selected and completed Self-report questionnaire and physical activity children with reminders 7 days (PAQ-C), Perceived physical competence questionnaire (PPFS), Perceived School Climate Questionnaire for physical activity (Am & et al,2005) and Social Support Questionnaire (Grier and et al, 2008). The BMI index and Lincoln Oseretsky Motor Skills Test was calculated for all subjects. Multiple regression analysis showed Children's fitness, physical competence, perceived climate of the physical environment and social support of  friends and family (social environment) are significant predictors for amount of children's  physical activity (P <0.5). In this regard, based on effect coefficients it would be say that Fitness (10%), physical competence (15%), Motor Skills (12%), physical environment (23%) and social environment (24%) can predict children's physical activity. According to results, it would be suggested using the well- known ecological variables to predict children's activities.

The purpose of this research was to investigate the environmentally friendly behavior of active sports tourists visiting Bushehr beach sports tourism destinations for beach and water sports. The research sample consisted of 102 active sports tourists who were selected by available method and completed the research questionnaire. The research tools included questionnaires of Eco-friendly compliance, Eco-friendly policy, Eco-friendly disposition and word-of-mouth advertisement by Kontojiani and Kotoris (2014). Frequency and percentage indices were used for descriptive statistics and structural equation modeling was done using PLS3 software in the inferential statistics section. The results showed that the Eco-friendly compliance of sports recreation centers providing coastal sports tourism services has a significant effect on the word-of-mouth promotion of active sports tourists, and also the Eco-friendly policy among sports tourists has a significant effect on the Eco-friendly disposition. Eco-friendly disposition did not have a causal relationship with the word-of-mouth advertising of sports tourists. The compliance of sports tourism service providers with environmental protection indicators did not have a significant effect on the Eco-friendly disposition, and this indicates that those sports tourists who have an Eco-friendly policy, in any situation, they show their Eco-friendly disposition. Considering the influence of the Eco-friendly policy on the Eco-friendly disposition of sports tourists, it is suggested that courses and educational programs in different platforms for members of the society, especially sports tourists, in order to familiarize themselves with environmental issues and improve the way and their environmental attitude should be done.
