在运动锻炼时,不少人都一味地强调运动强度,误认为运动强度越大越好。其实不然,过大的运动强度对人体健康非但无益反而有害,对于老年人来说更是如此。据医学研究表明:老年人的运动强度过大,会使机体内耗氧急剧增加,产生大量的“活性氧”,而“活性氧”是一种能够促使机体衰老的物质;同时,运动过于激烈或超时、超量,也会加剧人体某些器官的磨损。因此,老年人锻炼,宜选用运动强度相对较小的温和运动方式。 In sports exercise, many people blindly emphasize the intensity of exercise, mistakenly believe that the greater the better exercise intensity. In actual fact, excessive exercise intensity is not only harmful to human health but harmful, for the elderly is even more so. According to medical research shows that: the exercise intensity of the elderly is too large, will make the body oxygen consumption increased dramatically, resulting in a large number of “reactive oxygen species,” and “reactive oxygen species” is a kind of substances that can promote body aging; the same time, Overtime, excessive, will also exacerbate the wear and tear of certain organs of the human body. Therefore, the elderly exercise, should use a relatively mild exercise intensity mode of exercise.
