Effect of PEP'C-R on Endurance Parameters and Maximal Cardio-respiratory Function Among Sedentary Older Seniors Over 70

Study Overview
=================
Brief Summary
-----------------
The primary purpose of the protocol is to determine the effects of a new program of PEP'C PEP'C with constant load and intermittent recovery (PEP'C-R) on endurance parameters of older seniors. The study hypothesis: the investigators propose that PEP'C-R training offers a significant improvement in endurance parameters for older seniors. The secondary objectives are to determine the effects of PEP'C-R on maximal cardio-respiratory function, FMD (Flow-mediated dilation), PWV (pulse wave velocity), systolic and diastolic heart function, body composition (measured by impedance), biological, functional and cognitive functioning and quality of life.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: PEP'C-R<br>Subjects will benefit from one preliminary session and 18 sessions of PEP'C-R, (2 sessions per week for 9.5 weeks). | Other: PEP'C-R<br>* Preliminary session of calibration and tolerance: Test of Borg: determination of VT1 for 10 minutes, 3 min pedaling at 25 W and then 20 minutes pedaling on VT1 determined during the exercise test (ET) -10%. Session 1: 30 min of pedaling at constant load VT1 determined during exercise testing (EE) - 10%. Session 2 Session 17: increase in the burden of BASE (5 BASE * 5 min: 25 min) by 10% and decrease in relation to the load of the PIC (5 PIC * 1 min: 5 min) to get a cumulative charge of the same session. Changes in heart rate (HR) determine the evolution of sustained loads: a decrease of 10 bpm in heart rate leads to an increase by 10% in the intensity of the base (PIC load remains constant). Session 18 = Session 1.<br>|
| Active Comparator: Control group<br>Subjects do not participate in the program PEP'C-R and continue their usual activities at home for 9.5 weeks. | Other: Control group usual activities<br>* Participants in the control group will not follow the intervention PEP'C-R. They will continue their usual activities for 9.5 weeks and will be assessed before and after this period. After the study, they will be offered the benefit of the conventional program of the PEP'C.<br>|
