1
Why is bone health so important for women in particular?
2
It is driven by interplay between estrogen and progesterone.
3
We see peak velocity or peak bone mass hitting around the time we're 20-ish,
4
and then we'll start to degrade it if we're not creating multi-directional stress on the bone through resistance training.
5
And if we start to lose bone density and we become osteopenic or osteoporitic, they break easily.
6
It's really, really difficult for someone who is in their reproductive years to
7
be able to do all the things they want to do if they don't have a really strong, robust skeletal system.
8
And this is why vitamin D is also so important.
9
Yes.
10
And men and women have different bone density.
11
Yep.
12
Men have thicker bones and tend to not have as much degradation of the bone because they don't have estrogen,
13
progesterone perturbations that are changing the signaling to increasing bone density or stopping the growth of bone.
14
So, women have this perturbation throughout their menstrual cycle that will change how their bones are responding.
15
And then when we don't have a menstrual cycle or we get put on an oral contraceptive pill, we have changes in that signaling which changes our bone density.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
