“如果强度太大以至于你都想昏倒了，你绝对不能再继续进行这个锻炼进程了，这个进程对你来说太难了，你受伤或精力耗竭的风险都会因此而增加，”Burron说道。

"If it's so intense you're thinking of passing out, you can't continue this session for longer, then it's too difficult and you're at increased risk for injuries or burnout," Burron said.

但是，研究指出，即使伴有这一增加的风险，如果坐着不动超过4小时，罹患静脉血栓栓塞的绝对风险仍然相对较低，约为6000分之一。

However, the study points out that even with this increased risk, the absolute risk of developing VTE, if seated and immobile for more than four hours, remains relatively low at about 1 in 6000.

但是，只提相对风险（比如，风险增加100%），而忽略绝对比值（比如，患病概率为7千分之一）这类重要事实，非常容易误导大众。

Relative risks ("a 100% increase") are very misleading, however, when important facts like base rates are left out.
