Exercise interventions have the potential to reduce blood pressure in older adults, however, rates of exercise uptake and adherence are low, with 'lack of time' a commonly cited reason. As such, there remains the need for time-efficient physical activity interventions to reduce blood pressure in older adults. To compare the effect of three, novel time-efficient physical activity interventions on resting blood pressure in older adults. Forty-eight, healthy, community-dwelling older adults (mean age 71years) were recruited to a 6-week randomised control trial. Resting blood pressure was measured before and after one of three supervised, time-efficient interventions high-intensity interval training (HIIT) on a cycle ergometer; isometric handgrip training (IHG); unilateral, upper limb remote ischaemic preconditioning (RIPC) or non-intervention control. Both HIIT and IHG led to a statistically significant reduction in resting systolic blood pressure (SBP) of 9mmHg, with no significant change in the RIPC or control groups. There was no change in diastolic blood pressure or pulse pressure in any group. Supervised HIIT or IHG using the protocols described in this study can lead to statistically significant and clinically relevant reductions in resting SBP in healthy older adults in just 6weeks.

Although coronavirus disease 2019 (COVID-19) disproportionally affects older adults, the use of conventional triage tools in acute care settings ignores the key aspects of vulnerability. This study aimed to determine the usefulness of adding a rapid vulnerability screening to an illness acuity
