Strength Training Exercise for Acute Lymphoblastic Leukemia

(STEP-ALL Trial)

This trial explores how a structured strength training exercise program affects children newly diagnosed with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma. The researchers aim to determine if a 9-week exercise plan, combined with weekly symptom check-ins, is practical and beneficial during the first phase of chemotherapy, potentially improving physical function and overall wellbeing. The trial includes a mix of in-person and virtual sessions, allowing children to safely participate from home. Children newly diagnosed with ALL or lymphoblastic lymphoma who are medically able to exercise are encouraged to join. As an unphased trial, this study offers a unique opportunity for children to potentially enhance their wellbeing during treatment.

Research has shown that strength training can be safe for children with acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma. One study with a 12-week strength training program found no harmful effects. This program included high-intensity exercises that increased strength without causing any issues. Other research has also demonstrated that low- to moderate-intensity aerobic and strength exercises three times a week are safe. These findings suggest that the exercise plan for the trial is well-tolerated and offers a safe way to improve fitness during treatment.¹²³⁴⁵

Unlike the standard treatments for Acute Lymphoblastic Leukemia (ALL), which typically involve chemotherapy and targeted drug therapies, strength training exercise offers a non-pharmacological approach that aims to improve the physical health and quality of life for children with ALL. This method is unique because it focuses on enhancing muscle strength and overall well-being through physical activity, which can be particularly empowering for young patients. Researchers are excited about this trial because they hope to find out if regular exercise can serve as a supportive therapy, potentially reducing treatment side effects and improving recovery outcomes, thus offering a complementary approach to traditional medical treatments.

Research has shown that strength training can benefit children with acute lymphoblastic leukemia (ALL). Studies indicate that exercise enhances muscle strength, movement, and overall fitness in these children. This is crucial because their treatment often weakens muscles and reduces fitness. Other research suggests that exercise can also improve quality of life and help manage long-term side effects such as weight gain and heart problems. Additionally, regular exercise may boost mood and reduce fatigue. This trial will evaluate a structured exercise program as a key component in managing ALL in children.¹³⁶⁷⁸
