The purpose was to investigate the effect of different levels of exercise on memory and thinking strategies in athletic. athletes in a non-random sampling were selected based on inclusion criteria. Participants completed demographic questionnaires Control of thinking and meta-memory. Data were analyzed with MANOVA and Bonferroni post hoc test. Findings showed that there was a difference between the mean of meta-memory variable and memory satisfaction components, perception of daily memory ability, use of strategies, daily memory aids, thought control and distraction components, self-comparison, reassessment, social control and anxiety in skilled athletes. And a beginner is a significant difference.Skilled athletes had a higher average than skilled and beginner athletes in metamorphic variables and happy components of memory, perception of daily memory ability, use of strategies and daily memory aids, and skilled athletes in metaphysical variables and happy components of memory ability, memory. Everyday life, the use of strategies and daily memory aids were better than beginner athletes.The results also showed that the difference between the mean variables of mind control and distraction, self-comparison, reassessment, social control and anxiety in the three groups of expert, skilled and beginner was statistically significant. In the variable of controlling thoughts and reassessment components, the social athlete had a higher average than the beginner athlete's, and the beginner athlete had a higher average in the distraction, self-esteem, and anxiety components than the expert and skilled athlete. Having sports activity at national and international level leads to increased memory and thought control in young athletes.

The aim of the current research was to compare minigolf shots in beginner and expert players and analyze its kinematics. The present research was applied and semi-experimental and the research design was of causal-comparative research. The statistical population of this research was all the beginner and expert mini-golf players in Mashhad city. According to the limitations in the field of data processing,This is the moment when the putter is at its farthest point in the x direction. This process was done using Matlab software. Then the shoulder, elbow, hip and knee angle variables were calculated as an average and at the moment of impact. Also, the variables of putter speed, displacement and duration of swing of the putter from the moment of preparation to the time of impact were calculated. data collection, the obtained data were analyzed by independent t-test and Excel, Spss software. The results of the present research showed that there was a significant difference between the knee angle and the maximum linear speed of the putter in both beginner and expert groups (p≥0.05) and there was no significant difference in other variables between the two groups (p≤0.05). . Therefore, there was a difference between skilled and beginner players only in limited variables, but when referring to the average value, a significant difference was observed. It seems that the shape of the pattern should be close to that of skilled players in order to achieve a suitable pattern for beginner players and to train and train skilled players.

The aim of the current study was to examine the effect of the basketball net's height and skill level on the emergence of especial skill in basketball free throwing. To do this, ten experts (23±2.58) and ten less-expert (21.90±2.18) basketball players was taking 150 shots from five different distances from the basket including the free throw line. Players took their shots in the raised, standard and lowered basketball net's height. Two groups of the experts and less-experts threw 150 set shots in the raised, standard and lowered basketball net's height. The data was analysed based on Bayesian analysis applying a generalization model. The results reveal that the vision noise parameter in the model is quite constant (K vision=0.03). Also, the especial skill parameter showed the presence of the especial skill only in the experts when basketball net height was standard (a= 0.13). Whereas, the especial skill parameter showed no especial skill by the change of the basketball net's height in the experts. Furthermore, no especial skill was seen in the less-expert. These results proposed that besides the massive amount of practice, visual context information play critical role in the emergence of the especial skill and supported visual- context hypothesis.
