The acute physiological effects of high- and low-velocity resistance exercise in older adults

The aim of the present study was to determine if workload matched, high-velocity (HVE) and low-velocity (LVE) resistance exercise protocols, elicit differing acute physiological responses in older adults. Ten older adults completed three sets of eight exercises on six separate occasions (three HVE and three LVE sessions). Systolic blood pressure, diastolic blood pressure and blood lactate were measured pre- and post-exercise, heart rate was measured before exercise and following each set of each exercise. Finally, a rating of perceived exertion was measured following each set of each exercise. There were no significant differences in blood lactate (F(1,9) = 0.028; P = 0.872; ηP2 = 0.003), heart rate (F(1,9) = 0.045; P = 0.837; ηP2 = 0.005), systolic blood pressure (F(1,9) = 0.023; P = 0.884; ηP2 = 0.003) or diastolic blood pressure (F(1,9) = 1.516; P = 0.249; ηP2 = 0.144) between HVE and LVE. However, LVE elicited significantly greater ratings of perceived exertion compared to HVE (F(1,9) = 13.059; P = 0.006; ηP2 = 0.592). The present workload matched HVE and LVE protocols produced comparable physiological responses, although greater exertion was perceived during LVE

Can the Safety Net be Age-Friendly? How to Address Its Important Role in Caring for Older Adults with Geriatric Conditions

The safety net, a collection of public hospitals, federally qualified health centers (FQHCs), and publicly funded community-based healthcare entities, provides essential care to middle-aged and older adults with geriatric conditions. The role of the safety net for these adults will intensify over the next two decades with the growing numbers of middle-aged and older adults with adverse social determinants of health and premature geriatric conditions. The foundation for addressing their needs is to detect geriatric conditions and then focus care plans on the impact of these factors on function, which predicts mortality and quality of life more than chronic conditions alone. To detect geriatric conditions in safety net populations, the Age-Friendly Health System (AFHS) framework offers an evidence-based focus on the 4Ms: Mentation, Mobility, Medications, and what Matters. Further incorporating geriatric care models that target the 4Ms and are adapted to safety net populations will enable age-friendly care that optimizes health and addresses what matters to older people
