A study supported by the British Heart Foundation and published in the European Heart Journal, conducted by researchers at UCL, is the first to explore the link between different movement patterns throughout the 24-hour day and heart health. Cardiovascular disease is the leading global cause of mortality, responsible for one in three deaths in 2021. Analyzing data from 15,246 participants across six studies and five countries, the researchers found that moderate-vigorous activity provided the most significant benefit to heart health, followed by light activity, standing, and sleeping, in comparison to the adverse impact of sedentary behavior. Even small changes, like replacing as little as five minutes of sitting with moderate-vigorous activity, had noticeable effects on heart health. The study emphasizes the importance of considering various behaviors throughout the entire day for personalized recommendations to improve heart health.
