[Exercise capacity after mechanical ventilation because of COVID-19: Cardiopulmonary exercise tests in clinical rehabilitation].

Objective: To safely and effectively train the exercise capacity of post-COVID-19 patients it is important to test for cardiopulmonary risk factors and to assess exercise limitations. The goal of this study was to describe the exercise capacity and underlying exercise limitations of mechanically ventilated post-COVID-19 patients in clinical rehabilitation.

Design: A retrospective cohort study.

An Incremental Shuttle Wheel Test for Wheelchair Tennis Players.

Purpose: To determine the relationship between outcomes of the shuttle wheel test (SWT) and peak oxygen uptake (VOpeak) during that test and whether SWT and VOpeak can discriminate between different skill levels of wheelchair tennis players.

Methods: Fifteen wheelchair tennis players performed an SWT on a tennis court while VO was measured continuously. Outcome measures were VOpeak and achieved stage.

The energy cost for balance control during upright standing.

The aim of this study was to investigate whether balance control during a static upright standing task with and without balance perturbations elicits a significant and meaningful metabolic energy demand and to test whether this energy demand correlates with conventional posturography measures for balance control. Ten healthy subjects were assessed in four 4-min upright standing conditions on a force platform while energy consumption was measured using open circuit respirometry. In the reference condition subjects stood upright in parallel stance without balance perturbation (PS).
