运动强度是指动作时用力的大小和身体的紧张程度。决定运动负荷的主要因素之一。影响运动强度的因素主要有：练习的密度、练习的间歇时间、动作速度、练习所负的重量、要求投掷的距离、每次跳高的高度以及动作的难度和复杂性。运动强度对人体的刺激作用较大。适宜的运动强度能有效地促进身体机能的提高，增强体质。如果强度过大，超过身体的承受能力，反会使身体机能减退，甚至损害身体健康。

不同强度运动 different intensity exercise
“运动自觉量，即你对自己运动强度的自我感觉往往更为可靠，”赛事组资深编辑Matt Fitzgerald说道。
"The perceived exertion, your own sense of how hard you're working is a much more reliable of exercise intensity," said Matt Fitzgerald, senior editor of Competitor group.
当然，其实你身体的某些部分可能非常努力的运转了，但是在面对不同种类的运动时你应该问问自己这个运动强度够了么？
Yes, there are individual parts of your body that are being worked hard, but with every form of exercise you should ask yourself is it intensive enough?
