这里是省略了相同的主句及be动词，整句完整的话应该是：
The experiment shows that proper amounts of exercise, if the proper amouts of exercise is carried out regularly, can improve our health.
或者the proper amouts of exercise 可以用it代替。
懂了吗

实验表明：如果定期进行适量的练习，可以使我们更健康
这里的空为carried out
是一个省略句，原为if it is carried out regularly……可以将it is（主语，系动词）删除，it代表的是exercise……
