Study Arms:
- Chronic Respiratory Disease Group (Type: EXPERIMENTAL): Each patient receive the same intervention : 4 visits with different exercise tests.~Visit 1: Inclusion Visit, Functional Assessment and TTLM Speed Determination (6-minute walk test x2, cardiopulmonary exercise testing on ergocycle, questionnaires and accelerometer)~Visit 2 : Functional Evaluation and Shuttle Tests (ISWT, ESWT, Speed tests on 4m, Quadriceps muscle strength)~Visit 3 : Feasibility of the WTLT (WTLT x2 or 3)~Visit 4 : Reproducibility of the WTLT (WTLT x2) Specific measures for COPD subjects : Respiratory Functional Assessment and Dyspnea questionnaire
- Cardiovascular diseases Group (Type: EXPERIMENTAL): Each patient receive the same intervention : 4 visits with different tests.~Visit 1: Inclusion Visit, Functional Assessment and TTLM Speed Determination (6-minute walk test x2, cardiopulmonary exercise testing on ergocycle,, questionnaires and accelerometer)~Visit 2 : Functional Evaluation and Shuttle Tests (ISWT, ESWT, Speed tests on 4m, Quadriceps muscle strength)~Visit 3 : Feasibility of the WTLT (WTLT x2 or 3)~Visit 4 : Reproducibility of the WTLT (WTLT x2)
