Exercise Limitation after Critical Versus Mild COVID-19 Infection: A Metabolic Perspective.

Exercise limitation in COVID-19 survivors is poorly explained. In this retrospective study, cardiopulmonary exercise testing (CPET) was coupled with an oxidative stress assessment in COVID-19 critically ill survivors (ICU group). Thirty-one patients were included in this group.

Cardiopulmonary Exercise Testing in Critically Ill Coronavirus Disease 2019 Survivors: Evidence of a Sustained Exercise Intolerance and Hypermetabolism.

Unlabelled: To investigate exercise capacity at 3 and 6 months after a prolonged ICU stay.

Design: Observational monocentric study.

Setting: A post-ICU follow-up clinic in a tertiary university hospital in Liège, Belgium.

Biomechanical analysis of abdominal injury in tennis serves. A case report.

The serve is an important stroke in any high level tennis game. A well-mastered serve is a substantial advantage for players. However, because of its repeatability and its intensity, this stroke is potentially deleterious for upper limbs, lower limbs and trunk.
