Strength training following hematopoietic stem cell transplantation

Area of Science:

• Oncology
• Hematology
• Rehabilitation Medicine
• Exercise Physiology

Background:

• High-dose chemotherapy and hematopoietic stem cell transplantation (HSCT) significantly impair patients' physical activity and overall health status.
• Reduced physical activity and health deterioration are common challenges faced by patients post-HSCT.

Purpose of the Study:

• To evaluate the impact of strength training versus usual activity on physical activity, muscle strength, fatigue, health status, and quality of life after HSCT.
• To assess the feasibility and preliminary efficacy of a strength training intervention in the early recovery phase following HSCT.

Main Methods:

• A pilot study involving 19 subjects randomized into an exercise group or a control group.
• Strength training commenced post-hospital discharge, with measurements taken before HSCT admission, on day 8 post-HSCT, and 6 weeks after discharge.
• Key variables measured included physical activity levels, muscle strength, fatigue, perceived health status, and quality of life.

Main Results:

• A significant decline in physical activity, muscle strength, and health status was observed immediately after HSCT, followed by improvements at 6 weeks post-discharge.
• The strength training group reported significantly less fatigue compared to the control group.
• Trends indicated potentially higher physical activity in the exercise group, although interactions were not statistically significant.

Conclusions:

• Strength training shows potential benefits for improving physical activity, reducing fatigue, and enhancing quality of life in patients undergoing high-dose chemotherapy and HSCT.
• Preliminary evidence supports the use of strength training, utilizing accessible tools like elastic resistance bands, to promote early recovery after HSCT.
