Home-exercise Program for Children and Adolescent Survivors of Acute Lymphoblastic Leukemia

Exercise programs in children and teenagers with Acute Lymphoblastic Leukemia (ALL) strengthens their physical fitness. Exercising improves muscular and functional mobility fitness after finalizing chemotherapy in children and teenagers diagnosed with ALL. Assess cardiological changes

Children and adolescents survivors of ALL will be randomly assigned to the intervention group and to the control group. A home-exercise program will be designed for 16 weeks with 55 sessions, combining aerobic, strength and flexibility exercises of light and moderate intensity. The following tests will be performed to evaluate the effects of the intervention program: Echocardiography, Tape treadmill test using a ramp protocol to assess cardiorespiratory fitness, hand grip test to assess muscular grip strength, Timed Up test And Go Test (TUG) and Timed Up and Down Stairs Test (TUDS) to assess functional mobility, the sit and reach test to assess flexibility and a questionnaire to assess levels of physical activity. The control group will perform their usual physical activity

An exercise program will be designed over 16 weeks with 55 sessions, moderately increasing the volume and intensity of the load every 4 weeks. The program will consist of strength exercises, flexibility and aerobic endurance, which will be explained in videos and are going to be available in an online platform

The control group will be recommended to maintain a level of physical activity they would routinely and habitually have during the 4 months that the study will last.

The physiotherapist will contact the patient and/or tutor weekly so as to answer and doubts they may have with respect to the exercise program and to further supervise their compliance (group with intervention).

Index of the lateral mitral annulus level (isovolumetric contraction time + Isovolumetric relaxation time / ejection time), measured by Echocardiography. Index of TEI at the level of the septal mitral ring (isovolumetric contraction time + Isovolumetric relaxation time / ejection time), measured by means of Echocardiography. TEI index at the level of the tricuspid ring (isovolumetric contraction time + Isovolumetric relaxation time / ejection time), measured by means of Echocardiography.

For this variable the sit-and-reach (SR) test was used, that of which allowed evaluation of the hamstring muscle extensibility

This variable was measured utilizing the family of the international questionnaire of physical activity (IPAQ). For children between the ages of 8-12 the Physical Activity Questionnaire for Children (PAQ-C) version was used, and for adolescents between the ages of 13-18 the PAQ-A form was used.

Inclusion Criteria: The study included of children and adolescents between 7 and 18 years old that were at time in complete remission for a minimum of one year of their neoplastic disease and had finalized their chemotherapy treatments by the time they began the physical exercise program. Exclusion Criteria: Patients with structural cardiac anomalies, congenital cardiopathies, those in recurrence of their neoplastic diseases, signs of clinical or subclinical cardiac insufficiency and an echocardiography with alterations in systolic and/or diastolic function.
