Brief Summary
A multicentric, non-interventional study using a clinical questionnaire (SAPHIR) and activity monitor (Activ-PAL) to estimate the level of physical activity in the general population. This study compares the level of physical activity reported by the SAPHIR questionnaire with the activity recorded by the activity monitor during the same period, in order to determine if the SAPHIR score is able to represent the measured physical activity, in a simple and easily calculable manner. Hypothesis: The aim of this work is to propose a new questionnaire that is simple to complete by the patient,quick to analyse and directly calculable by the doctor and adapted to the general population, whether during the initial evaluation or the follow-up. Indeed, these scores are rarely used outside the context of the prescription of physical activity in specialized centers. Moreover, a tool suited to the constraints of community medicine seems necessary, given the growth of the prescription of physical activity in primary care. The idea behind this new questionnaire is to obtain a score ranging from 0 to 100 that can be calculated through simple mental arithmetic, which is not the case for most existing questionnaires, in particular the IPAQ.

Outcome Measures
Primary Outcomes (1)
correlation between SAPHIR score completed at inclusion and the level of physical activity estimated from measurement data collected using the Activ-PAL® activity monitor
A score is based on the time spent at each intensity level of physical activity, using the correlation between cadence and METs extrapolated from the literature (Tudor-Locke et al, 2020). The primary outcome measure is the correlation coefficient between the amount of physical activity estimated by the SAPHIR score and that estimated from the Activ-PAL data.
7 days
Secondary Outcomes (5)
correlation between the final SAPHIR score (completed at the end of the measurement week) and the amount of physical activity calculated from the Activ-PAL® activity monitor data
7 days
correlation between the initial SAPHIR score and the IPAQ score (baseline)
inclusion
correlation between the final SAPHIR score and the final IPAQ score
7 days

Eligibility Criteria
The study population consists of patients referred for consultation in the department of sports medicine (generally active patients, although patients may also be sedentary and/or inactive) or in the department of vascular medicine (patients with lower limb peripheral artery disease, mostly inactive)
You may qualify if:
- Patients referred for a consultation at one of the participating centers
- Patients over 18 years old with no upper age limit
- Patients with a contra-indication to walking
- Professional athletes or patients participating in endurance sports competitions
- Patients refusing to participate in the study
- Patients unable to understand the objectives or instructions of the study
You may not qualify if:
- Patients with Activ-PAL recordings of less than 3 days
