Exercise speeds up aging | 运动老更快！45年万人研究揭:运动不会让人变长寿

Not only does exercise have nothing to do with longevity, it may also make people age faster. After a 45-year survey of 11,000 same-sex twins, the University of Jyväskylä in Finland published this research conclusion that goes against popular belief and stated that high-level exercise has no additional benefits on lifespan, and People who exercised the most were “older” by up to 1.8 years than those who were less active.

According to the New York Times, the research team divided the subjects into four groups: sedentary group, moderate activity group, active group and highly active group. After calculating all data from 1975 to 2020, they found that the amount of exercise Those who were least likely to die were 20% more likely to die than those who exercised regularly, but after filtering out factors such as education, BMI, smoking and drinking, this number dropped significantly, with the sedentary group only 7% more likely to die. .

The team pointed out that this result shows that “too little or too much exercise will accelerate aging”, that is, moderate exercise is enough, and people who exercise regularly do not live longer because of exercise, but “they usually live healthier lives.” It is worth mentioning that although this study was recognized by Finland’s National Sports Medicine Award, it has not yet undergone peer review.

In addition, most relevant past studies have concluded that regular exercise has positive benefits for lifespan. The WHO also recommends that adults aged 18 to 64 should engage in 150 to 300 minutes of moderate aerobic exercise, or 75 to 150 minutes of high-intensity exercise per week. Aerobic exercise.

运动不仅与长寿无关，更可能让人老得更快。芬兰于韦斯屈莱大学（University of Jyväskylä ）经过长达45年、针对11,000名同性双胞胎调查后，发表这项有违大众认知的研究结论，并指高水平运动对寿命没有额外好处，且最常运动的人比活动量较少的人“年长”达1.8岁。

据《纽约(专题)时报》报导，研究团队将受试者分为久坐组、中等活动组、活跃组与高度活跃组等4组，并在计算1975年至2020年间所有数据后，发现运动量最少的人比经常运动的人死亡可能性高出20％，但过滤掉教育、BMI、抽烟及饮酒等因素后，该数字就显着下降，其中久坐组的死亡可能性仅高出7％。

团队指出，这结果表明“运动量过少或过多都会加速老化”，也就是适度运动即可，且经常运动的人不是因为运动变更长寿，而是“他们通常过着更健康生活”。值得一提的是，该研究虽获得芬兰的国家运动医学奖表扬，但尚未经过同行评审(Peer review）。

此外，过去相关研究大多认定经常运动对寿命有正面助益，WHO也建议18岁至64岁成年人每周应进行150分钟至300分钟中等有氧运动，或75分钟到150分钟的高强度有氧运动。
