Purpose: The purpose of this study was to investigate the effect of attention instructions on kinesthesia of memory, alpha and theta wave changes in professional basketball players. Method: Thirty-six male athletes were randomly assigned into three groups: internal attention, external attention, and control. A quasi-experimental research design with a pretest-posttest design including experimental and control groups was applied. In the pre-test, kinesthesia of memory, free throw, and 5- blinded brain waves on baseline were measured. In the acquisition phase, participants performed 20 attempts on the coordination test under four conditions (40-40°, 80-80°, 40-80°, 80-40°). The internal attention group focused on the movement of their limbs while moving, while the external attention group focused on the purpose and angle of movement. The retention test was conducted one day later, and the transfer test was conducted two days after the acquisition test. Results: Practicing a sense of movement showed significant progress. There were also significant interactive effects with the group. The results within each group showed that the effect of training sessions on theta and alpha waves was significant. Conclusion: The results support the constrained action hypothesis and the conscious processing hypothesis, suggesting that external focus requires less attention than internal focus. The non-optimal increase of alpha waves resulting from internal attention led to performance impairment. The decrease in alpha waves also led to increased sensory processing of information and improved performance. [ABSTRACT FROM AUTHOR]

Objectives. This study aims to investigate whether mento-physical exercises can decrease mental fatigue during shift work. Methods. Research subjects including the control room staff of an urban train system were chosen randomly, for whom mental fatigue was assessed before and after rest breaks for control and experimental groups. A new protocol was applied in the experimental group, including breathing exercises, isometric and isotonic exercises, and progressive relaxation during the inter-shift break. A designed questionnaire and the Stroop test were used to evaluate fatigue and the reaction time, respectively. Results. Pre and post-test results showed that mental, visual and physical fatigue and reaction time decreased by 14.48, 49.22, 26.85 and 8.35% in the control group and 36.42, 48.48, 76.37 and 20.56% in the experimental group, respectively. Conclusions. At the 5% α level, Student's t test showed that mento-physical exercises effectively decreased mental and physical fatigue as well as reaction time in the experimental group compared to the control group.
