Lifestyle Sedentary

There are few studies that already have validated specific raw accelerometer cut-points for people over 65 years old. The purpose of the present study is to validate raw accelerometer cut points for general people over 65 years old and specific raw accelerometer cut points based on the functional status of older adults over 65 years old. The study will be carried out with an observational approach. Participants will be divided into 4 groups. First of them will be made grouping all subjects and the rest divided according to their functional status. They will perform different-intensity physical activities while wearing accelerometers attached to their body and wearing a portable gas analyser too. Their intensity will be assessed based on their own Rest Metabolic Rate (RMR). Energy expenditure and accelerations will be matched and, based on that, sedentary behaviour, light physical activity and moderate-to-vigorous physical activity cut-points will be derived.

Introduction: Regular practice of exercise or physical activity (PA) is a recognized intervention as a determinant of good health acquisition, maintenance, or recovery for a large number of chronic pathologies. Nevertheless, few studies have evaluated adherence to an initial health-adapted PA (APA) program, and persistence of active behavior over the time in individuals with a chronic disease. The aim of the study is to determine the brakes and levers associated with motivation and long-term compliance. In addition, the investigators aim to evaluate the cost-effectiveness of such program in term of care consumption. Finally, the investigators complete their interest for APA prescription from practitioners agreeing to enroll their patients in the present study. Method: The investigators perform a prospective monocentric cohort, of 2024 patients affected of a chronic disease or long-term illness (LTI), enrolled from 2021 to 2024 (4 years, 506 per year), for a 16-week APA program, and followed 5 years with an annual fitness and habits of life and care consumption evaluation.
