フィジカルトレーニング
Green exercise refers to physical exercise undertaken in natural environments. Physical exercise is well known to provide physical and psychological health benefits. There is also good evidence that viewing, being in, and interacting with natural environments has positive effects, reducing stress and increasing the ability to cope with stress, reducing mental fatigue and improving concentration and cognitive function. The concept of Green exercise has therefore grown out of well-established areas such as the attention restoration theory within environmental psychology which have tended to focus on the psychological and physical effects of viewing nature (e.g., see the work of Kaplan and Ulrich) and well-recognised work about the psychological benefits of physical exercise.
