More Weekly Movement Tied to 30% Lower Heart Risk

Heart risk was more than 30% lower among adults logging 560 to 610 minutes each week of movement ranging from moderate effort to vigorous exertion. That total may sound daunting, but it works out to about 80 minutes daily. Brisk walks, bike rides, hikes, swimming, running, fitness classes and active travel all contributed when they increased heart rate.

Researchers studied 17,088 UK Biobank participants whose average age was 57. Each person wore a wrist-based motion tracker for one week, giving the team an objective picture of everyday activity. Fitness was also assessed through VO2 max, which reflects the body’s ability to take in and use oxygen while exercising. The researchers then recorded heart attacks, strokes, heart failure and atrial fibrillation across nearly eight years.

At the familiar target of 150 minutes per week, the study found an 8–9% reduction in cardiovascular risk. The association grew stronger as weekly movement rose. Fitness level mattered alongside time spent active, suggesting that equal exercise totals can accompany different cardiovascular conditioning. The findings preserve the value of the standard benchmark while showing that additional movement throughout the day was linked with greater heart protection.
