Objective: To determine the level of cardiorespiratory fitness in patients with chronic low back pain and to establish factors limiting the maximal effort during the ergometry Methods: Patients performed a maximal exercise test to measure V ̇O2max. Clinical endpoints of the tests were determined and grouped as maximal effort and symptom‐limited effort. Results: 101 patients aged 29.8 achieved a V ̇O2max value of 30 ml.kg‐1.min‐1. When compared to normative categories, men and women were situated in the fair category. Quadriceps/leg fatigue was the most frequent limiting factor. Symptom limited effort endpoints were reported by 54.4% of the subjects. An association between the clinical endpoint and the accomplished V ̇O2 value was established. Maximal effort is associated with a V ̇O2max value while symptom‐limited effort is associated with a V ̇O2peak value. Conclusions: Clinical limiting factors of maximal exertion interfere the achievement of maximal oxygen uptake in patients with chronic low back pain. Further, there exists an association among the clinical endpoints of the tests and the V ̇O2 value achieved. Chronic low back pain patients have a lower level of aerobic fitness than healthy controls.
