Background: The aim of this study was to determine the effectiveness of UK government COVID-19 safe offices policy to increase stair use in a higher education setting during the COVID-19 pandemic. Methods: Automated counts at 3 ground floor staircases and the elevator entrances were used to estimate stair to elevator use ratio for ascent and descent from/to the ground floor of a university building at baseline (January to March 2020), first and second intervention months (October 2020, November 2020, respectively). Stair promoting signage and a 1-way system was implemented, in line with government policy. Results: At baseline, stair to elevator use ratio for ascent from and descent to the ground floor was 1.36 (0.02) and 1.88 (0.02) people, respectively. The ratio significantly increased in the first intervention month to 2.64 (0.09) and 3.96 (0.22) people for ascent and descent, respectively. However, the ratio decreased between the first and second intervention months to 1.63 (0.06) and 3.05 (0.52) people for ascent and descent, respectively. Conclusion: The UK government COVID-19 policy was effective at increasing stair use in a higher education setting. [ABSTRACT FROM AUTHOR]

Background: The aim of the study was to provide an isotemporal substitution model to predict how changes in physical behavior may affect the cardiovascular parameters (CVPs) of older adults. Methods: Participants wore a thigh-mounted accelerometer for 7 days. Phenotype of the carotid, brachial, and popliteal artery was conducted using ultrasound. Isotemporal substitution was used to simulate the degree to which replacing 1 hour of physical behavior with another would affect CVP. Results: Substitution of sedentary behavior with Standing and sporadic moderate- to vigorous-intensity physical activity (MVPA accumulated in bouts <10 min) would reduce resting heart rate [-6.20 beats per minute (-12.1 to -0.22) and -3.72 beats per minute (-7.01 to -0.44), respectively]. Substitution of sedentary behavior with light-intensity physical activity would reduce carotid artery diameter [-0.54 mm (-1.00 to -0.07)]. Substitution of Standing with sporadic MVPA would increase popliteal artery diameter [1.31 mm (0.11 to 2.51)]. Conclusions: Our modeling suggests that an accumulation of MVPA bouts that are shorter than the recommended 10-minute minimum may still improve CVP, with lower intensity physical activity also influencing CVP. Our findings are a promising avenue for lifestyle interventions in older adults to reduce the aging effects on CVP for those who cannot engage or sustain sufficient MVPA. [ABSTRACT FROM AUTHOR]
