In sport context, the motivational climate created by significant others (e.g., coachs and peers) has been influences on the athletic-student's motivation, engagement, performance, and skill development. Collective efficacy is important for team performance because it influences a group's task choice, effort expenditure, persistence in the face of failure, and resistance to discouragement. This study was to examine the influence of peer motivational climate (i.e., task-involving and ego-involving motivational climate) and coach autonomous support for basic psychological need satisfaction and collective efficacy. In the study, participants were 289 athletic-students' of team sports. In the study then, questionnaire was assessed using by the correlation and path analysis. The results showed that task-involving motivational climate significantly predicted of collective efficacy, while ego-involving motivational climate were negatively predict to the collective efficacy. The results suggest the importance of considering peer influence in addition to coach influence when examining motivational climate in team sport.
PURPOSE This study aimed to examine the mediating effect of psychological needs in the relationship between multiple coaching styles and teamwork among college football players. METHODS This cross-sectional study involved 526 elite football players. Descriptive statistics, reliability analysis, confirmatory factor analysis, correlation analysis, path analysis, and macroprocess were performed using statistical software to test the mediation effects of the data collected. RESULTS The findings suggested that autonomy-supportive and structure coaching styles positively correlated with and impacted psychological needs satisfaction and teamwork. Conversely, control and chaos coaching styles negatively correlated with and impacted psychological needs satisfaction and teamwork. In addition, autonomysupportive and structure coaching styles negatively correlated with and impacted psychological need frustration, while control and chaos styles positively correlated with and impacted psychological needs frustration. Furthermore, psychological needs satisfaction and frustration were found to partially mediate the relationships between autonomy support and teamwork, structure and teamwork, control styles and teamwork, and chaos styles and teamwork. CONCLUSIONS Autonomysupportive and structure coaching styles positively influenced teamwork by satisfying psychological needs. In contrast, control and chaos coaching styles negatively impacted teamwork by contributing to psychological needs frustration.
The cerebellum is one of the major parts of the brain involved in the motor control including motor coordination, muscle tone, balance, and the learning of motor skills. The purpose of this review paper was to explore of pathophysiology, anatomical function and neurophysiological mechanism for cerebellum. For this, we sought to examine of previous study related cerebellar disease. Specifically, this paper suggested that motor deficiency of limb movements, coordination, gait/posture balance, adaptation of during movement execution through information proprioception or kinaesthesia, and motor planning and programming of cerebellar patients. We expect that this review will be able to offer the useful information to research. For example, movement scientists will provide an academic information about cerebellar ataxia. Patients and their families will provide relevant information to the daily life (e.g., management and rehabilitation exercise).
