Psychological states affect focus of attention and play a mediating role in its effect on motor performance and learning. The present study investigated the effect of practice under psychological pressure and attention focusing with instruction on learning billiard shot. Participants were 48 female volunteer students (19-23 years old) who were randomly selected and assigned to 4 experimental groups (internal focus under high and low pressure, external focus under high and low pressure). The groups practiced for 8 sessions after the pretest. Acquisition test was performed in the last session of practice, and the retention test was conducted with 2 and 10 days of delay after the last practice session. The accuracy of the shots was scored according to the distance of the ball from the pit. The results of U Mann-Whitney test showed priority of internal attention in the acquisition and 10-day delay retention tests and priority of practice under low pressure in 10-day delay retention test (P<0.05). The results of Kruskal–Wallis test and pairwise comparisons indicated priority of the acquisition of internal attention under high pressure on external attention under high pressure and the priority of delayed retention of internal attention under low pressure on external attention under high pressure (P<0.05). It seems that given the nature of skill in terms of unchanged environmental conditions and high accuracy and attention requirements especially in the early stages of learning, practice under low psychological pressure conditions and internal focusing will result in more delayed retention for novice people

Increased level of stress has negative effects on cognitive functions. Thus, it is necessary to identify appropriate strategies to prevent cognitive and motor performance decline. The aim of this research was to study the effect of immobilization stress on learning and memory and the protective role of physical activity in them. From male Albino-Wistar rats of Pastor Institute, 32 rats were randomly divided into four groups. According to the type of the groups, rats were exposed to stress interventions including immobilization (two hours per day for 21 days), moderate running (30 minutes per day for 21 days), combination of stress interventions and running and also without any interventions. In order to determine the effectiveness of stress, animal weights were measured in two phases: before the protocol and after the tests. Morris Water Maze in several steps (four days for the acquisition phase, the fifth day for Probe test, three days for resting and the ninth day for recall test) was used for learning and testing of rats. ANOVA test with repeated measures and paired sample t test in acquisition phase and Tukey post hoc test were used to analyze data. The results revealed that stress damaged learning and memory (P=0.03). However, physical activity neutralized performance damage caused by stress (P=0.000). Physical activity group showed a significant positive effect on the time to reach the platform in the acquisition phase (P=0.005) and on cognitive function in recall phase (P=0.006) which was a sign of positive effect of physical activity on learning and memory. Therefore according to the present results which show that stress impairs learning and memory, it is expected that physical activity will be used as an effective factor to moderate stress.

The aim of the present study was to investigate the relationship of the perception of the peer motivational climate, stress and the weekly training with burnout in junior elite athletes of Kerman province. The statistical population consisted of 120 male elite athletes from Kerman province from individual and team sports (table tennis, karate, taekwondo, badminton, cycling, handball, volleyball, basketball, football) who continuously trained at Kerman championship gym in 1391 with the age range of 15–19 years and at least 4 years of experience of participating in a sport field with medals in Iran championships. 92 athletes were randomly selected using Cochran formula. To collect data, peer motivational climate questionnaire (Ntoumanis and Vazou, 2005), athletes' burnout questionnaire (Raedeke and Smith, 2001) and perceived stress scale (Cohen et al., 1983) were used. Finally, personal demographic forms were used to determine the weekly training hours, acquired positions, the duration of activity, age and sport field. To analyze the data, Pearson correlation coefficient, multivariate regression, scatter plot and independent t test were used. The results showed a negative and significant relationship between all peer motivational climate components (except for intra-team conflict) and all burnout components (P<0.05). There was a positive relationship between intra-team conflict and burnout but this relationship was not significant (P≥0.05). There was a positive and significant relationship between perceived stress and all burnout components (P<0.05). There was no significant relationship between weekly training hours and burnout and its components (P≥0.05). Also, there was no significant difference in burnout, perception of peer motivational climate, stress and weekly training hours between individual and team sports (P≥0.05). Finally, the statistical results for prediction of burnout showed that 47.7% of burnout could be explained by the perception of peer motivational climate, stress and weekly training. In addition, stress was the dominant predictor of burnout. The results showed that paying attention to the role of peers and controlling stress during burnout process can guarantee to decrease this phenomenon in junior elite athletes and can improve their performance and stability in sport.
