This study is designed to evaluate the reproductibility and the performance of the 3 minutes sit-to-stand test in patients with idiopathic pulmonary fibrosis. To do this, the investigators are recruiting 40 patients with idiopathic pulmonary fibrosis in 2 centers (Grenoble university hospital and Lyon university hospital). Patients had to achieve an effort test on a cycle ergometer. 2 visits are planned in the hospital. During each visit, patients will perform a 3 minutes sit-to-stand test, a 1 minute sit-to-stand test and a 6 minutes walk test. During the second visit, patients will also perform a 3 minutes sit-to-stand test with measurement of oxygen uptake. The investigators will then analyse the results by comparing numbers of cycle, functional response and symptoms during the 3 minutes sit-to-stand test of the 2 visits. The investigators will also compare the functional response obtained during the 3 minutes sit-to-stand test, the 1 minute sit-to-stand test and the 6 minutes walk test. Finally, the investigators will compare the maximal values of oxygen uptake, respiration rate and expired volume obtained during the 3 minutes sit-to-stand test to the effort test on cycle ergometer.

Reproductibility of the 3 minutes sit-to-stand test in patient with idiopathic pulmonary fibrosis
Evaluate the reproductibility for the number of rise and down during the 3 minutes sit-to-stand test of the 2 visits (the investigators will compare the number of rise and sit during the 3 minutes sit-to-stand test of the 2 visits to see if they are similar)
Time frame: 2 days
Functional response during the 3 minutes sit-to-stand test: Oxygen saturation
Evaluate the reproductibility of functional response (oxygen saturation) during the 3 minutes sit-to-stand test
Time frame: 2 days
3 minutes sit-to-stand test compared to the 6 minutes walk test: oxygen saturation
compared oxygen saturation during the 3 minutes sit-to-stand test to the 6 minutes walk test
Time frame: 2 days
1 minute sit-to-stand test compared to 3 minutes sit-to-stand: oxygen saturation
Compared oxygen saturation during the 3 minutes sit-to-stand test with 1 minute sit-to-stand test
Time frame: 2 days
Functional response during the 3 minutes sit-to-stand test: Heart rate
Evaluate the reproductibility of functional response (heart rate) during the 3 minutes sit-to-stand test
Time frame: 2 days
Functional response during the 3 minutes sit-to-stand test: symptoms
Evaluate the reproductibility of functional response (symptoms) during the 3 minutes sit-to-stand test
Time frame: 2 days
3 minutes sit-to-stand test compared to the 6 minutes walk test: heart rate
Compared heart rate during the 3 minutes sit-to-stand test to the 6 minutes walk test
Time frame: 2 days
3 minutes sit-to-stand test compared to the 6 minutes walk test: symptoms
Compared symptoms during the 3 minutes sit-to-stand test to the 6 minutes walk test
Time frame: 2 days
1 minute sit-to-stand test compared to 3 minutes sit-to-stand: heart rate
Compared heart rate during the 3 minutes sit-to-stand test with 1 minute sit-to-stand test
Time frame: 2 days
1 minute sit-to-stand test compared to 3 minutes sit-to-stand: symptoms
Compared symptoms during the 3 minutes sit-to-stand test with 1 minute sit-to-stand test
Time frame: 2 days
