概括

在体位训练之前可以通过减少能量消耗来改善平衡. 通过压力中心 (CoP) 摆动的变化测量这种效应,在训练后至少持续5小时.

科学领域:

神经科学
生物力学
人类生理学

背景情况:

姿势控制对于平衡至关重要,并涉及复杂的感觉运动集成.
之前的研究表明运动活动可以影响后续的姿势学习和表现.

研究的目的:

研究作为运动活动对健康成年人的姿势学习的影响.
将与手握对姿势控制参数的影响进行比较.

主要方法:

16名健康志愿者在各种支持和视觉条件下进行双脚和单脚姿势评估.
参与者在单脚姿势训练前进行2分钟的或节奏手握.
在训练前和训练后测量压力中心 (CoP) 参数,包括速度,路径长度和摇摆面积,并在5小时后进行后续检查.

主要成果:

在单脚姿势的姿势训练导致两组的CoP速度和路径长度下降.
握手组的身体摇摆面积减少,而组的摇摆面积保持不变,但能量消耗减少 (表面的功率长度).
在训练后5小时,单脚姿势参数的改善与双脚姿势的变化相关.

结论:

与手握相比,有助于保持较低的能量成本和更高的可适应性.
在单脚姿势转移到双脚姿势的姿势训练适应,受先前运动活动的影响.
在体位训练之前可以通过优化能量消耗来提高平衡,尽管需要进一步的研究来证实平衡的安全性.

Cognitive Learning

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...
