目前我個人只能看到 abstract，希望能有神人可以看到整篇文章；中譯的部分
已經盡個人所能了，如果錯誤歡迎指正 Orz
就 abstract 來說：
Background People who are physically active have at least a 30% lower
risk of death during follow-up compared with those who are inactive.
However, the ideal dose of exercise for improving longevity is
uncertain.
背景 常運動的人死亡風險低過不運動的人至少 30%。不過增進壽命的最佳
運動量是不確定的。
Objectives The aim of this study was to investigate the association
between jogging and long-term, all-cause mortality by focusing
specifically on the effects of pace, quantity, and frequency of jogging.
研究目的 此研究僅針對慢跑的「跑速、跑量和實施頻率」對於長期、全因素
死亡率之間的關聯性。
Methods As part of the Copenhagen City Heart Study, 1,098 healthy
joggers and 3,950 healthy nonjoggers have been prospectively followed
up since 2001. Cox proportional hazards regression analysis was performed
with age as the underlying time scale and delayed entry.
研究方法 作為哥本哈根市心臟研究的一部分，自 2001 起長期追蹤 1,098 位
慢跑者及 3,950 位健康的不跑步者。以年紀為時序基礎利用回歸分析出害處比例。
Results Compared with sedentary nonjoggers, 1 to 2.4 h of jogging per
week was associated with the lowest mortality (multivariable hazard
ratio [HR]: 0.29; 95% confidence interval [CI]: 0.11 to 0.80).
The optimal frequency of jogging was 2 to 3 times per week (HR: 0.32;
95% CI: 0.15 to 0.69) or 1 time per week (HR: 0.29; 95% CI: 0.12 to
0.72). The optimal pace was slow (HR: 0.51; 95% CI: 0.24 to 1.10) or
average (HR: 0.38; 95% CI: 0.22 to 0.66). The joggers were divided into
light, moderate, and strenuous joggers. The lowest HR for mortality was
found in light joggers (HR: 0.22; 95% CI: 0.10 to 0.47), followed by
moderate joggers (HR: 0.66; 95% CI: 0.32 to 1.38) and strenuous joggers
(HR: 1.97; 95% CI: 0.48 to 8.14).
（這段落落長，數值部分請原諒中文部分不摘要了）
研究結果
與久坐不跑步的參考組比較，每週慢跑 1 至 2.4 小時呈現最低死亡率。
最佳的實施頻率為每週跑 2 至 3 次或是每週 1 次。
最佳跑速為緩慢或一般。
慢跑強度再分「輕、中及強」，最低傷害率發生在輕度跑者上，其次是中度跑者，
最後是強度跑者。
Conclusions The findings suggest a U-shaped association between
all-cause mortality and dose of jogging as calibrated by pace,
quantity, and frequency of jogging. Light and moderate joggers have
lower mortality than sedentary nonjoggers, whereas strenuous
joggers have a mortality rate not statistically different from that
of the sedentary group.
結論 研究結果認為全因素死亡率與慢跑量（隨跑速、跑量及實施頻率校正）
呈現 U 型相關。輕度及中度跑者與久坐不跑者相比有較低的死亡率，而強度
跑者與久坐不跑者的死亡率在統計學上沒有差別。

原來的 paper 跟新聞報的差了十萬八千里... 到底是哪裡出問題呢？
※ 引述《firstkiki (洛晴)》之銘言：

: 這是英文新聞的原文，中文的內容根本亂拼亂湊
: Numerous studies have associated physical activity with reduced mortality,
: with some suggesting that just small amounts of exercise can do the job.
: A recent study reported by Medical News Today, for example, claims that a
: daily 20-minute brisk walk could reduce the risk of early death by 16-30%.
: 許多研究表示身體活動可降低死亡率
: 今日醫學新聞報導最近的一項研究，例如每日快走可減少16~30%的早死風險

: The link between lower levels of exercise and reduced mortality is supported
: with this latest study, which suggests light jogging is most beneficial for
: lowering the risk of premature death.
: 這研究中證實低強度運動和降低死亡率是有關連性的
: 慢跑是最有利減少早死率的運動
: To reach their findings, Dr. Schnohr and colleagues analyzed 5,048 healthy
: individuals who were a part of the Copenhagen City Heart Study.
: Of these, 1,098 were joggers and 3,950 were sedentary non-joggers.
: 分析對象1098個跑者跟3950個久坐不跑者
: (最後研究統計跑者是878 久坐不跑者是413)
: Jogging more than a few times a week at a strenuous pace 'may be harmful'
: 高強度慢跑超過幾次"可能有害"
: During the study, there were 28 deaths among joggers and 128 among non-joggers.
: The team notes that overall, the joggers were younger, had a lower prevalence
: of diabetes and smoking, and had lower blood pressure and body mass index
: (BMI).
: 研究過程中有28個跑者死亡(我去找paper看圖表是寫17人)
: 128個不跑者死亡
: 該團隊指出，整體而言，有跑步的人會較年輕，低糖尿病患病率和較少抽菸，
: 而且血壓跟身體質量指數都較低
: Dr. Schnohr notes that light jogging in this study represents vigorous exercise
: , while strenuous jogging represents very vigorous exercise.
: "When performed for decades, this activity level could pose health risks,
: especially to the cardiovascular system," he adds.
: Dr. Schnohr指出輕度慢跑在這項研究是屬於劇烈運動，
: 而更高強度的慢跑是非常劇烈的運動
: 他補充說，當此活動進行了幾十年，可能會造成健康風險，尤其是心血管系統。

: Conclusions:
: The findings suggest a U-shaped association between all-cause mortality and
: dose of jogging as calibrated by pace, quantity, and frequency of jogging.
: Light and moderate joggers have lower mortality than sedentary nonjoggers,
: whereas "strenuous joggers have a mortality rate not statistically different

: 請看最後一句
: "劇烈運動跟久坐不動者的死亡率在統計學上無明顯差異"
: Perspectives
: COMPETENCY IN MEDICAL KNOWLEDGE:
: Compared with more sedentary people, people who jog regularly exhibit a
: significantly lower all-cause mortality rate. Those who jog lightly or
: moderately appear to benefit more than strenuous joggers,
: whose long-term mortality rate is similar to that of sedentary people.
: COMPETENCY IN PATIENT CARE: When prescribing exercise to improve longevity,
: strenuous exercise is not necessary and might reduce the health benefits
: of light to moderate physical activity.
: TRANSLATIONAL OUTLOOK: Further studies are needed to explore the mechanisms
: by which excessively strenuous exercise adversely affects longevity before
: the pattern of association between exercise intensity and long-term mortality
: can be incorporated into physical activity recommendations for the general
: public.
: 最後一段說，在探討過度強烈運動的不利影響之前，
: 還需要先研究探討運動強度跟長期死亡率的關聯性。

: : 1周快跑4次 死亡率比慢跑增9倍
: 統計數據上，快跑死亡率跟慢跑死亡率比較，快跑較高
: 但研究中無法證實快跑會增加死亡率
: : 丹麥最新研究指出，快跑等激烈運動長期有損健康，增加死亡風險，速度適中的慢跑才是
: : 長壽最佳秘訣。
: 研究中沒有說會"增加"死亡風險，是數據比較的高低而已
: 記者自己斷章取義加油添醋還蠻厲害的
: : 哥本哈根腓特烈斯貝醫院的團隊，研究1098名健康跑者與413名健康但不運動者，追蹤期
