Abstract

The aim of this study was to compare the effects Errorless, Error full and scaling equipment methods on accuracy of the throw basketball under stress in children. 50 elementary boy students 10-12 years randomly divided into five groups (errorless, error full, Training with scaling and standard equipment, scaling equipment and combined). After 5 session in acquisition, retention and transfer (under stress) tests were conducted. Revised Competitive State Anxiety Inventory-2 was filled out by participants before retention and after transfer tests. Data was analyzed with dependent t-test and mixed ANOVA. Significant reduction were found between retention and transfer tests in training with standard equipment group. Performance of standard equipment group declined under pressure. However, performance Decrement in other groups was not significant. In general, according the results of this study, the use of scaled equipment by children lead to implicit learning in the same manner as the errorless learning paradigm and prevents choking under stress. Therefore, it can be used as a proper method for teaching motor skills in children.

Abstract

Executive dysfunction is a hallmark of traumatic brain injury (TBI) and is associated with significant complications. Deficiency in problem-solving, emotion regulation, and attention is one of the most common phenomena after brain injury. This study aimed to evaluate the effectiveness of short-term intervention of dual executive function on problem-solving, emotion regulation, and selective attention in patients with traumatic brain injury. This quasi-experimental design used pre-test and post-test with a control group. Twenty subjects with brain injury were selected with the Purposive sampling method. They were randomly entered into two experimental and control groups (10 in the experimental group and 10 in the control group). After performing the pre-test, the experimental group received the short-term intervention and double executive function in 8 sessions of 90 minutes, while the control group did not receive any intervention. The assessment was performed in two stages of pre-test-post-test using a set of software tests of the Tower of London, Stroop and John and Gross (2003) Emotion Regulation Questionnaire. Analysis of covariance was used to analyze the data. The results showed a significant difference in the mean scores between the experimental group and the control group in all variables after the test. Therefore, it can be concluded that short-term intervention of dual executive function has a significant effect on improving attention, emotion regulation, and problem-solving in people with traumatic brain injury.

Abstract

The effectiveness of different educational methods in learning different types of motor skills has been considered. However, comparisons of these methods in regulated team sports games have been less studied. Therefore, the aim of the present study was to compare the three educational methods of imagery, observation, and execution of in-field pattern on the performance of regulated games in skilled basketball players.15 players working in the country's Super League and Premier League competitions participated in this study with available access. The players were divided into 3 teams of 5 players according to the position of the game and were subjected to one of three training conditions in each stage based on random classification; So that each team performed all three methods randomly in each stage. Each condition included 1 practice session and a written and practical test session (after 24 hours). The players observed each tactic 3 times in the observation conditions; In terms of imagery, 3 trials were made for each tactic, and the execution conditions included 3 slow execution of tactics inside the field. The results of mixed analysis of variance 3 (training method) in 2 (written and practical test) showed that the execution method compared to observation and imagery causes better performance in regulated games (P <0.05); Also in the written test, the observation method scored higher than the imagery (P <0.05). Therefore, it seems that the field execution method for teaching team tactics in skilled players, has a greater advantage than the observation and imagery method, but the mental imagery is also more effective in acquiring knowledge of team tactics than observation.
