Why Getting Winded Might Be Six Times Better for Your Heart

New research suggests that pushing your pace — really pushing — may do far more good for your heart than a leisurely walk. Vigorous-intensity exercise has been found to be up to six times more effective at reducing cardiovascular risk than moderate activity like brisk walking. This comes from a large study out of the University of Sydney, which tracked tens of thousands of adults using wearable activity monitors. The results showed that every minute of vigorous activity (think fast running, cycling, or other high-effort aerobic movements) provided a much stronger protective effect on heart health than six minutes of moderate exercise. ([The Independent][1]) What does “vigorous” mean in practice? According to the lead researchers, it’s activity during which your heart pounds, breathing becomes hard, and you can’t speak full sentences comfortably. (*The Independent][1]) Examples can include fast running, swimming, or climbing stairs — basically anything that makes your body work hard and fast. Why does the intensity matter so much? Studies suggest that vigorous exercise more effectively strengthens the heart, improving its capacity to pump blood and enhancing cardiorespiratory fitness. ([Lippincott Journals][2]) These adaptations are more powerful and efficient than what many moderate activities typically provoke. Still, walking has its place. Walking (especially brisk walking) does reduce cardiovascular risk, and for many people — including those with health challenges — it’s a very valuable form of movement. ([PubMed][3]) But the new insights highlight that if you have the capacity for more intense exercise, even short bursts can deliver big benefits. In real terms, adding just a few vigorous minutes to your weekly routine could be more impactful than adding more walking time. (*The Independent+*1+) That doesn’t mean everyone needs to train like an athlete, but it does suggest that when heart health is the goal, intensity can be a powerful ally.
