【摘要】：目的:随着我国人民生活水平提高及国家对体育产业的支持,全民健身逐渐成为风尚。拥有一个好的体魄,不但是工作学习的基础,更是陪伴家人、享受生活的保障。当今社会,在闲暇时安排健身计划已经成为现代人不可或缺的日常活动。健身要讲究科学,不当的健身方式可能对健康产生不良的影响,而适宜的方式能产生事半功倍的效果。以往研究表明,与健身活动带来的其他收益如体脂改变、心肺功能提高等相比,健身使人心情愉快是更重要的增进健康因素。那么如果在健身活动中存在异性,是否由于这种愉快感,从而提高健身的效益呢?这是值得从自然科学的角度进行证明的。本研究通过对受试者在独自条件下进行负重深蹲训练,以及与异性陪同完成负重深蹲训练两种训练形式。以事件相关电位P300作为检测手段,研究异性效应在负重深蹲训练中对大脑认知功能的影响。方法:随机抽取山东师范大学长清湖校区男性15名、女性22名作为本实验受试者。采用哑铃负重深蹲的训练手段,对受试者独自训练前、独自训练后进行事件相关电位检测,获得个人组训练前后脑电数据。间隔两天以上后,对其在异性陪同下训练前后进行事件相关电位检测,获得异性组训练前后脑电数据。结果:(1)男性异性组训练后P300波幅较男性异性组训练前显著性降低(P0.05)。而男性个人组训练前后P300波幅无显著性差异。(2)女子个人组训练前后及异性组训练前后P300波幅、潜伏期、反应时均无显著性差异。(3)性别差异分析显示,在异性组训练后P300波幅方面,女性受试者较男性受试者波幅更高。(4)性别差异分析显示,在异性组训练后P300潜伏期方面,女性受试者较男性受试者潜伏期时间更长。结论:独自进行负重深蹲训练对大脑认知功能的影响不明显,男性进行负重深蹲训练存在异性效应,表现为注意力投入的能力降低。在异性陪同下进行负重深蹲训练,女性的注意力投入能力高于男性。信息加工的速度低于男性。这种结果可能是由于训练或异性效应两种因素叠加的效果。
[Abstract]:Objective: with the improvement of our people's living standards and the support of our country to the sports industry, the national fitness has gradually become a fashion. Having a good physique is not only the basis of work and study, but also the company of family members. Enjoy the security of life. In today's society, it has become an indispensable daily activity for modern people to arrange fitness plans in their leisure time. Previous studies have shown that compared with other benefits such as body fat changes and cardiopulmonary function improvements, Fitness makes people happy is a more important factor to improve health. So if there is the opposite sex in fitness activities, because of this sense of pleasure, thereby improving the effectiveness of fitness? This is worth proving from the point of view of natural science. As well as the two training forms of weight-bearing squat training with the escort of the opposite sex. The event-related potential P300 is used as the detection method. To study the effect of heterosexual effect on cognitive function of brain in weight-bearing squat training. Methods: 15 males and 22 females in Changqing Lake Campus of Shandong normal University were randomly selected as subjects. Before and after training alone, the subjects were tested for event-related potentials, and EEG data were obtained before and after training. After the interval of more than two days, the event-related potentials were detected before and after training with the opposite sex. Results the P300 amplitude of male heterosexual group was significantly lower than that of male heterosexual group before and after training, but there was no significant difference in P300 amplitude between male group and male group before and after training. P300 amplitude before and after training, There was no significant difference in latency and response time. Gender difference analysis showed that the amplitude of P300 in female subjects was higher than that in male subjects. Conclusion: the effect of weight-bearing squat training alone on the cognitive function of brain is not obvious, and there is heterosexual effect of male training on weight-bearing squat training. It shows that the ability to pay attention is reduced. The weight bearing squat training is carried out with the opposite sex. Women's attention input ability is higher than that of men, and the speed of information processing is lower than that of men's. This result may be due to the combination of training or heterosexual effects.
