Less-fit individuals must exercise more weekly to gain the same heart benefits, study finds
A UK Biobank study of over 17,000 adults followed for about eight years found that meeting the NHS guideline of 150 minutes per week reduces cardiovascular risk by ~8-9%, but the least fit participants needed about 30-50 extra minutes weekly to achieve the same benefit. Greater risk reductions require even more activity (370 minutes for ~20% risk reduction for least fit vs 340 minutes for most fit; >610 minutes for >30% reduction vs ~560). The findings suggest higher activity levels may be needed for optimal protection, though experts caution against pushing extreme weekly totals; public health guidance remains that 150 minutes is beneficial for all, with more providing added protection.
