Key result
Regular moderate-to-vigorous physical activity provides cardioprotective benefits that far outweigh the potential risks of maladaptive cardiac remodeling associated with high-intensity regimens.
Why the study?
Despite established cardioprotective benefits of exercise, vigorous physical activity can trigger acute cardiac events in susceptible individuals, and high-volume, high-intensity regimens may induce maladaptive cardiac remodeling.
What are the physical activity thresholds for optimizing cardiovascular health outcomes, and does high-intensity exercise pose cardiovascular risks?
What are the physical activity thresholds for optimizing cardiovascular health outcomes, and does high-intensity exercise pose cardiovascular risks?
While extreme high-volume, high-intensity exercise may be associated with maladaptive cardiac remodeling, regular moderate-to-vigorous physical activity provides cardioprotective benefits that far outweigh the risks for the vast majority of individuals.

Supports moderate activity recommendations; leaves high-intensity thresholds open for prospective trials.
Franklin et al. (2023) conducted a review in Cardiovascular disease. Physical activity was evaluated. Regular moderate-to-vigorous physical activity provides cardioprotective benefits that far outweigh the potential risks of maladaptive cardiac remodeling associated with high-intensity regimens.
