Effects of Upper Extremity Aerobic Exercise Training in Hematopoietic Stem Cell Transplantation Recipients

Overview

Hematologic malignancy is a tumor of myeloid or lymphatic cells that affects lymph nodes with the involvement of blood, bone marrow or other organs.There are various treatment options for hematological malignancies ranging from follow-up to single or multiple agent chemotherapy, radiotherapy, immunotherapy and autologous or allogeneic hematopoietic stem cell transplantations (HSCT). The general recommendation for patients is to relax and avoid intense exercise, regardless of the devastating consequences of neglecting physical exercise. Patients also go to relaxation by reducing their activity to avoid fatigue, which leads to loss of muscle strength and endurance. As a consequence of all, fatigue, vomiting, weight loss, anemia, depression, decreased aerobic capacity, muscle weakness, decreased physical function and poor quality of life are observed in HSCT recipients. It has been shown that physical exercises improve oxygen consumption, depression and fatigue, cardiorespiratory fitness, muscle strength and physical well-being in patients with hematologic malignancies who are at stages of various treatments. In literature, effects of upper extremity aerobic exercise training have been investigated in patients with spinal cord injury, neuromuscular diseases, claudication, hypertension, multiple sclerosis, heart failure, paraplegic patients and healthy individuals. Results of these studies has shown that upper extremity aerobic exercise training improves walking distance, increases oxygen pulse, muscle strength and endurance of upper extremity. No study was observed to investigate the effects of upper extremity aerobic exercise training on exercise capacity and quality of life in HSCT recipients, as we know. For this reason, our aim is to investigate the effects of upper extremity aerobic exercise training on exercise capacity and quality of life in HSCT recipients.

Minimum 30 allogeneic and autologous HSCT recipients (˃100 days past post-transplant status) will be included. Before and after 6-week upper extremity aerobic exercise training, maximal and submaximal exercise capacity, respiratory and peripheral muscle strength, pulmonary functions, physical activity, dyspnea and fatigue perception, anxiety, depression and quality of life were evaluated. Primary outcome measurements were exercise capacity and quality of life , secondary outcomes were respiratory and peripheral muscle strength, pulmonary functions, physical activity, dyspnea and fatigue perception, anxiety and depression.
