Exercise sets up a chain reaction that is generally positive for the human body, preventing and controlling some health problems. However, endurance sports, requiring the sustained
2、efforts for long periods of time, reveal a darker side of exercise.从控制体重到延长寿命,定期锻炼使人们受益匪浅。 运动会建立一个连锁反应,通常对人体有益,可以预防和控制一些健康问题。 然而,耐力运动需要长时间的持续努力,揭示了运动的阴暗面。 A common endurance sport is marathon. Running 26.2 miles is an achievement, but its ultimately harmful. In one study, about 75% of marathon runne
3、rs suffered from kidney injury after finishing the race. Similarly, cross-country skiing offers excellent cardiovascular benefits when performing at a leisurely pace. Yet cross-country skiing alters the structure of the heart, making it more easily damaged to an arrhythmia, a condition where the hea
4、rt beats irregularly. When it came to the participants hearts, competitive success in cross-country skiing doesnt always translate into better health. The most extreme endurance races, such as Ironman Triathlons, provide more discouraging data.一项常见的耐力运动是马拉松。 跑 26.2 英里是一项成就,但最终是有害的。 在一项研究中,大约 75% 的马拉
5、松运动员在完成比赛后遭受了肾损伤。 同样,越野滑雪在以悠闲的速度进行时提供了极好的心血管益处。 然而,越野滑雪会改变心脏的结构,使其更容易因心律不齐而受损,这是一种心脏不规则跳动的情况。 当谈到参与者的内心时,越野滑雪的竞争成功并不总是转化为更好的健康。 最极端的耐力赛,例如铁人三项,提供了更多令人沮丧的数据。 Endurance athletes face another serious problem: they may drink much water while competing.

Evidently, ex
7、treme endurance sports can transform the basic necessity of drinking water into a potential source of harm.耐力运动员面临另一个严重问题:他们在比赛时可能会喝很多水。 运动时适当补充水分是健康和表现的关键。 但是,太多的好东西可能是危险的。 据报道,超过 10% 的铁人三项参与者患有低钠血症,发生在血液中钠水平变得危险的低水平时,通常是在水中钠浓度过低时。 显然,极限耐力运动可以将饮用水的基本需求转化为潜在的伤害来源。 Does running help a person live lon

However, running distances and speeds beyond this was not tied to higher rates of survival. This finding demonstrat
9、es no exercise is better for ones health than excessive exercise in endurance sports.跑步能延长人的寿命吗? 发表在 Mayo Clinic Proceedings 上的一项研究得出结论,每周以每小时 6 到 7 英里的速度跑步 0.1 到 19.9 英里与较低的死亡风险有关。 然而,超出此范围的跑步距离和速度与更高的存活率无关。 这一发现表明,没有什么运动比耐力运动中的过度运动更有益于一个人的健康。 Certainly, none of this means that exercise in moderati
