Recent data indicates a correlation between increased weekly physical activity and enhanced cardiovascular protection, suggesting that current health guidelines may be insufficient for optimal outcomes.

近期數據顯示，每週增加身體活動量與提升心血管保護之間存在相關性，這顯示目前的健康指南可能不足以達到最佳成效。

A longitudinal study conducted by Macao Polytechnic University, involving approximately 17,000 British adults aged 40-69, examined the relationship between cardiorespiratory fitness (VO2 max) and cardiovascular disease. The findings indicate that while adherence to the World Health Organisation (WHO) and NHS guidelines—specifically 150 minutes of moderate activity or 75 minutes of vigorous activity per week—yields a modest risk reduction of 8-9%, optimal protection is associated with significantly higher volumes. Specifically, the data suggests that 560 minutes for fit individuals and 610 minutes for unfit individuals per week may reduce cardiovascular risk by over 30%.

由澳門理工大學進行的一項長期研究，對象約為 17,000 名 40 至 69 歲的英國成年人，探討了心肺適能（最大攝氧量 VO2 max）與心血管疾病之間的關係。研究結果顯示，雖然遵循世界衛生組織（WHO）和 NHS 的指南——即每週 150 分鐘中強度活動或 75 分鐘高強度活動——能帶來 8-9% 的適度風險降低，但最佳保護則與顯著更高的活動量相關。具體而言，數據顯示，健康者每週活動 560 分鐘，不健康者每週活動 610 分鐘，可將心血管風險降低 30% 以上。

Despite these findings, academic and clinical perspectives suggest that the relationship between activity and health is incremental rather than binary. Professor Aiden Doherty of the University of Oxford asserts that the data continue to support existing WHO guidelines, noting that any increase in activity correlates with a reduction in risk. Consequently, the pursuit of 'optimal' volumes may be impractical for the general population due to socioeconomic and temporal constraints. To mitigate the fact that one-third of UK adults fail to meet minimum guidelines, practitioners suggest the implementation of 'exercise snacks'—brief, high-intensity bursts of activity—and 'micro-walks' to enhance insulin sensitivity and glucose regulation.

儘管有這些發現，學術與臨床觀點認為活動量與健康之間的關係是遞增的，而非二元的。牛津大學的 Aiden Doherty 教授主張，數據仍支持現有的 WHO 指南，並指出任何活動量的增加都與風險降低相關。因此，由於社會經濟和時間限制，追求「最佳」活動量對一般大眾而言可能並不切實際。為了緩解三分之一英國成年人未能達到最低指南的情況，專業人員建議實行「運動零食」（exercise snacks）——即短時間、高強度的爆發性活動——以及「微散步」（micro-walks），以提升胰島素敏感度與血糖調節。

Furthermore, the integration of strength training and varied intensity levels is recommended to improve functional capacity. Clinical observations indicate that vigorous-intensity activity is necessary to strengthen the cardiac muscle, whereas light activity primarily benefits energy expenditure. Strategies such as interval walking or consolidated 45-minute sessions incorporating mobility, strength, and aerobic work are proposed as sustainable alternatives to the high-volume requirements identified in the study.

此外，建議整合重量訓練與不同強度等級，以提高功能能力。臨床觀察顯示，高強度活動對於強化心肌至關重要，而輕微活動則主要有助於能量消耗。研究提出了一些可持續的替代方案，例如間歇式行走，或將靈活性、力量和有氧訓練整合在 45 分鐘的課程中，以取代研究中確定的高活動量要求。

While higher volumes of exercise correlate with superior heart health, current guidelines remain a valid baseline, with incremental increases in activity providing cumulative benefits.

雖然較高的運動量與更優的心臟健康相關，但目前的指南仍是一個有效的基準，活動量的遞增能提供累積的益處。
