PurposeThe aim of this study was to evaluate the effects of a home-exercise programme on physical fitness indicators and physical functioning after completion of chemotherapy in children and adolescents diagnosed with acute lymphoblastic leukaemia (ALL).MethodsTwenty-four survivors of ALL were assigned to usual care (control group, n = 12, 11.0 ± 3.7 years) or to a home-exercise programme (intervention group, n = 12, 11.8 ± 4.3 years). Peak oxygen uptake (VO2peak ml/kg/min), minute ventilation (VE L/min), output of carbon dioxide (VCO2 L/min), respiratory exchange ratio (RER), peak heart rate (beats/min), maximal load (W), VO2 at anaerobic threshold (VO2 at AT, ml/kg/min), pulse oxygen (PO2 ml/beat), heart rate at anaerobic threshold (beats/min), handgrip test (pounds), flexibility (cm), Timed Up & Go test TUG (s), and Timed Up and Down Stairs test (TUDS s) were measured at baseline and over 16 weeks of intervention.ResultsAdjusted mixed linear models revealed a significant group-time interaction + 6.7 (95% CI = 0.6-12.8 ml/kg/min; η2 partial = 0.046, P = 0.035) for VO2peak. Similarly, changes in mean values were observed after the home-exercise programme compared with baseline for VE (L/min) - 8.8 (3.0) (P = 0.035), VCO2 - 0.2 (0.08), (P = 0.041), maximal load (W) - 35.5 (12.8) (P = 0.024), TUDS (s) 0.8 (2.6) (P = 0.010), and TUG (s) 0.6 (0.1) (P = 0.001); however, the group-time interaction was not significant.ConclusionThe home-exercise programme resulted in changes in measures of VO2peak, VE, VCO2, and functional capacity during daily life activities (TUDS and TUG test). This is an interesting and important study that surely adds to the current body of knowledge/literature on the safety of exercise interventions, especially in children with haematological cancer.
