How Different Types of Physical Activity Reduce the Risk of Death
不同類型的身體活動如何降低死亡風險
Introduction
Recent long-term research shows that specific amounts of strength training and walking are linked to a lower risk of death and heart disease.
最近的長期研究顯示，特定 amount 的重量訓練與步行，與降低死亡及心臟病風險相關。
Main Body
A 30-year study of over 147,000 participants, mostly women, examined the link between weight training and a longer life. The results suggest that about 120 minutes of strength training per week—including both weights and body-weight exercises—is connected to a 13% reduction in overall death and a 19% reduction in heart-related deaths. Furthermore, the best health results occurred when participants combined this strength training with aerobic exercise. While aerobic activity alone provided the greatest overall benefits, combining both types of exercise offered a powerful way to reduce health risks.
一項針對超過 147,000 名參與者（大部分為女性）的 30 年研究，探討了重量訓練與長壽之間的關聯。結果顯示，每週約 120 分鐘的力量訓練——包括重量訓練與自重練習——與整體死亡率降低 13% 及心臟相關死亡率降低 19% 相關。此外，當參與者將力量訓練與有氧運動結合時，健康效果最顯著。雖然單純的有氧活動帶來最大的整體益處，但結合兩種運動則是降低健康風險的強有力方式。
Another study focused on older women, with an average age of 72, to see how daily step counts affected health over 11 years. The findings show that walking 4,000 steps a day, even if only done once or twice a week, is associated with a 26% reduction in overall mortality. Although walking more frequently reduced the risk further, the data emphasized that the total number of steps is more important than how many days a week the person walks. Consequently, this evidence suggests that the common goal of 10,000 steps may be unnecessary, as lower targets can still provide significant health benefits for older women.
另一項研究聚焦於平均年齡 72 歲的年長女性，旨在觀察 11 年間每日步數如何影響健康。研究結果顯示，每天行走 4,000 步，即使每週僅執行一次或兩次，也與整體死亡率降低 26% 相關。雖然增加行走的頻率能進一步降低風險，但數據強調，總步數比每週行走的天數更重要。因此，這項證據表明，普遍追求的 10,000 步目標可能並非必要，因為較低的目標仍能為年長女性提供顯著的健康益處。
Conclusion
Current evidence indicates that moderate strength training and basic walking goals can significantly help people avoid premature death.
目前的證據顯示，適度的力量訓練與基本的步行目標，可以顯著幫助人們避免早逝。
Vocabulary Learning
🧩 The 'Connecting' Secret: Moving from A2 to B2
At an A2 level, students often write short, choppy sentences like: "Walking is good. It reduces risk. 10,000 steps are not necessary."
To reach B2, you must use Logical Bridges (Connectors). These words act like glue, showing the reader how two ideas relate to each other. Look at how this article does it:
⚡ The 'Adding' Bridge: Furthermore
Instead of just saying "and," the author uses "Furthermore."
- Usage: Use this when you have already given one strong point and want to add an even stronger one.
- Example: "Strength training is beneficial. Furthermore, combining it with aerobic exercise is even better."
⚖️ The 'Contrast' Bridge: Although
A2 students use "but" at the end of a sentence. B2 students use "Although" to start a complex thought.
- Usage: It introduces a fact that makes the main point surprising.
- Example: "Although walking more frequently reduced the risk further, the total number of steps is more important."
🎯 The 'Result' Bridge: Consequently
Stop using "so" for every result. "Consequently" is the professional version.
- Usage: Use this to show a direct mathematical or logical result of the previous sentence.
- Example: "Lower targets provide benefits. Consequently, the 10,000-step goal may be unnecessary."
