1周快跑4次　死亡率比慢跑增9倍 - 健身

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
from that of the sedentary group."

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

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

研究中沒有任何數據證實快跑"傷身"

總結，就記者自己加了幾筆混淆視聽
