Cai et al. analyze accelerometer data from UK Biobank participants using machine learning to separate sporadic from bouted moderate-to-vigorous physical activity (MVPA) and link them to mortality and cardiovascular outcomes. They find that 150 min/week of sporadic MVPA yields maximal mortality benefit, and adding bouted MVPA offers further gains.
