对摔跤运动员启蒙训练的探讨

优秀的摔跤运动员必须经过启蒙训练。启蒙训练必须经过4个阶段：首先是选拔运动员。其次是培养运动员对本项目的兴趣和爱好。第三是进一步做到掌握运动员在运动中产生的情绪，引导运动员如何克制情绪反应。然后是进行“三从一大”的训练方法。

The impact of individual efficacy beliefs on group goal selection and group goal commitment

Collective efficacy research has begun to progress from simply trying to verify the relationship between collective efficacy and performance to examining the mechanisms through which collective efficacy impacts on performance. To test hypotheses concerning the impact of collective efficacy on group goal selection and commitment, 24 participants were assigned to triads (consisting of the participant and two confederates) and performed two time-trials on cycle ergometers. Before each trial, the participants were asked to select both a finishing time and position goal for their group and to indicate their commitment towards these goals. After trial 1, the participants were assigned to either a high or low collective efficacy condition and received appropriate bogus performance feedback. Analysis of variance and post-hoc tests revealed that participants in the low collective efficacy group significantly reduced both finishing time and group position goals from trial 1 to trial 2, whereas participants in the high collective efficacy group maintained their goals. These results provide support for Bandura's suggestions concerning the mechanisms through which collective efficacy impacts upon performance.     

Cricket bowling deliveries and the discrimination ability of professional and amateur batters

Bowlers in cricket try to disguise their bowling action by movement pattern similarity. The batter's task is, therefore, to solve rapidly perceptual discrimination problems. Previous research has suggested that batters can discriminate perceptual cues that provide depth or target information. However, at present, there is a lack of applied research evidence on further perceptual cue utilization, including bowling delivery identification. This ability is required when batting against wrist-spin bowlers who may use five different types of delivery. In the present study, we assessed this perceptual discrimination ability among three distinct standards of batters. In addition, the relative potency of body action and ball flight information was assessed by visual occlusion techniques. We found that more expert batters in general showed greater perceptual discrimination skills when faced with different ball types. However, this discrimination ability was linked specifically to delivery type and to previous experience. We also found that additional ball flight information provided no more advantage to this discrimination ability. This finding reinforces the importance of advanced cue information and the need to expose cricket batters to different bowling actions. Further study of the development of movement pattern recognition is recommended.
