Individual physical activity profiling in older adults: Reforming the assessment of dose-response relationship (PA-REFORM)<\/strong><\/h3>\n

Reassessment of the exercise dose-response relationship in the era of wearables<\/strong><\/h3>\n

Our understanding of older people\u2019s physical activity in relation to recommendations is based on flawed models that don\u2019t account for an individual\u2019s ability to move. Methods based on movement speed or volume may underestimate the actual load experienced by an older person. In this project we are using wearable technology and machine learning methodology to examine physical activity and internal load of exercise in older people.<\/p>\n

Initial data collection in 2017-2018 was done in the AGNES study<\/a> with 75-, 80- and 85-year-old people, and involved physical activity surveillance for one week using two wearable sensors: an accelerometer and a heart rate monitor. We repeated the activity assessments in 2021-2022 and will be following participants\u2019 health until 2025.<\/p>\n

We will develop a new method for quantifying physical activity in older people, which takes into account individual differences in physical capacity, and will make it possible to develop individualised physical activity recommendations.<\/p>\n
