Adults may need far more weekly exercise than current guidelines recommend to achieve a major reduction in the risk of heart attack and stroke, according to findings from an observational study published online in the British Journal of Sports Medicine.
The researchers found that substantial cardiovascular protection was associated with 560 to 610 minutes of moderate-to-vigorous physical activity each week. That amount is roughly 3 to 4 times higher than the current public health recommendation of at least 150 minutes per week.
Moderate-to-vigorous activities include brisk walking, running, and cycling.
Fitness Level May Change Exercise Needs
The study also suggests that people with lower fitness levels may need slightly more exercise than highly fit individuals to receive similar cardiovascular benefits.
