Estimating cardiopulmonary fitness with a new sampling technology in patients with rheumatoid arthritis-associated interstitial lung disease.

Background And Objectives: Although peak oxygen uptake (VO ) is one of the most important measures in clinical practice, the high cost and time consumption have led to the search for simpler devices and the development of the estimating cardiopulmonary fitness (eCPF) equation. Since the lungs are one of the sites most affected by rheumatoid arthritis (RA), this study aimed to create a predictive equation for VO obtained by simple sampling technology in women with RA-associated interstitial lung disease (RA-ILD).

Methods: This cross-sectional study evaluated 47 women with RA-ILD.

Kinematic evaluation of patients with chronic obstructive pulmonary disease during the 6-min walk test.

Background: A better understanding of gait kinematics during the 6-min walk test (6MWT) may facilitate the development of rehabilitation strategies for patients with chronic obstructive pulmonary disease (COPD).

Aim: To evaluate gait kinematics during the 6MWT in patients with COPD.

Method: Thirty-six patients with COPD and 19 healthy controls underwent a full-body kinematic analysis during the 6MWT.

Are the group-based interventions improving the functional exercise capacity and quality of life of frail subjects with chronic heart failure?

Objectives: Frail subjects with chronic heart failure (CHF) often demonstrate limited tolerance of exertion, shortness of breath, and reduced walking capacity resulting poor quality of life (QoL). The aim of this study was to quantify the improvements in functional exercise capacity (FEC) and QoL among Bulgarian frail subjects with CHF performed group-based high-intensity aerobic interval training (HIAIT)/m-Ullevaal intervention and to compare it with moderate intensity continuous training (MICT) protocol.

Methods: One hundred and twenty (n=120) frail subjects with mean age of 63.
