I tried to move to, like, an altitude training group, switched coaches.

我试着转到，比如，一个高原训练组，换了教练。

For example, there are special training groups where children are taught things like looking at other children while talking to them, --- talking about other people's interests, and even smiling.

例如，有一些特殊的培训小组，孩子们被教导在与其他孩子交谈时要注视他们，---谈论其他人的兴趣，甚至微笑。

Now to the results, which frankly won't take long because, although both the 2-day and 4-day training groups showed progress across all measured muscle and strength outcomes, which is great, there were no significant differences between any of them.

现在来看看结果，这不会花很长时间，因为，尽管 2 天和 4 天的训练组都显示了肌肉和力量的测量结果有进步，这很好，但它们之间没有显著差异。
