Effect of Ground-Based Walk Training in Pulmonary Hypertension

Abstract

© 2022 Elsevier Inc.This study aimed to determine the effect of ground-based walking training on exercise capacity, physical activity, quadriceps muscle strength, and quality of life (QoL) in patients with pulmonary hypertension. A total of 24 patients were included in the study. Patients were randomly assigned to 2 groups as the walking group or the control group. The walking group participated in 30-minute supervised ground-based walking training 2 days/week for 8 weeks. Also, they walked unsupervised at least 1 day/week. The control group received no intervention. The number of weekly steps taken in both groups was recorded using a pedometer. In addition to the sociodemographic and clinic characteristics of the patients, the endurance shuttle walk test, incremental shuttle walk test, and 6-minute walk test were used for the evaluation of exercise capacity, and an activity monitor and pedometer for physical activity, a dynamometer for quadriceps muscle strength, and emPHasis-10 for QoL. After 8 weeks, endurance capacity, maximal exercise capacity, and the number of steps significantly improved in the walking group (p 0.05). The results of the study showed that ground-based walking could improve endurance capacity, maximal exercise capacity, and the number of steps. Quadriceps muscle strength also improved in the walking group. No adverse effects were reported during the training period. Ground-based walking training can be performed safely in patients with pulmonary hypertension.
