如何理解运动训练的生理本质?

答案

参考答案:

“刺激-反应-适应”是生物机体具有的基本特征。机体或一切活组织具有对刺激发生反应的能力,表现在当体内外环境发生变化时,细胞组织或机体内部的新陈代谢及外部的表现形式都将发生相应的变化。机体若长期生活在某一特定的环境中,则可逐渐形成一种与环境相适应的反应模式,表现在对长期施加于机体的各种刺激,通过自身形态、结构与功能的改变以适应这一刺激,从而提高机体对环境变化的适应能力。

TOKYO —Imagine a bicycle seat connected by mechanical frames(机械支架) to a pair of shoes for an idea of how the new wearable assisted-walking machine from Honda works.

The experimental machine, showed on Friday, is designed to support bodyweight, reduce stress on the knees and help people organize steps and stay in crouching(蹲坐) positions.Honda showed a video of its employees wearing the machine.

Engineer Jun Ashihara also said the machine is useful for people standing in long lines and to people who run around to make deliveries.

"This should be as easy to use as a bicycle," Ashihara said."It reduces stress, and you should feel less tired."

To wear it, you put the seat between your legs, put on the shoes and push the “on” button.Then just start walking around.

In a test run for media, this reporter found it does take some time to get used to the machine.  “I could sense how it supported my moves, pushing up on my bottom when I crouched and pushing at my soles(脚底) to help lift my legs when I walked,” he said.

The system has a computer, a motor, gears(齿轮), batteries and sensors in it, so it responds to a person's movements, according to Honda Motor Co.

Pricing and commercial product plans are still undecided.Japan's No.2 automaker will begin testing a prototype(模型) later this month.

The need for such mechanical help is expected to grow in Japan, which has one of the most rapidly aging societies in the world.

Other companies are also eyeing the potentially attractive market of helping the weak and the old get around.Japan is among the world's leading nations in robotics technology, not only for industrial use but also for entertainment and companionship.
