Brief Summary
This study compared the effects of constant-load aerobic exercise (CL-AEx) and graded aerobic exercise (G-AEx) on cardiopulmonary fitness and functional capacity in pediatric survivors of acute lymphoblastic leukemia (ALL). A cohort of 72 pediatric ALL survivors was randomly assigned to one of three groups: a CL-AEx group (n=24), a G-AEx group (n=24), or a control group (n=24). All groups participated in a structured exercise regimen. The CL-AEx group performed additional moderate-intensity aerobic training at a fixed load, while the G-AEx group performed additional aerobic training with progressive increases in intensity and duration. The control group performed the structured exercise regimen only. Interventions were administered three times per week for 12 consecutive weeks. Cardiopulmonary fitness and functional capacity were assessed in all three groups at baseline and following the completion of the 12-week intervention.

Study Arms (3)
CL-AEx group
EXPERIMENTALThe CL-AEx group received a 12-week constant-load aerobic training besides a structured exercise program.
G-AEx group
EXPERIMENTALThe G-AEx group received a 12-week intensity- and duration-graded aerobic training in addition to a structured exercise program.
Control group
ACTIVE COMPARATORThe control group received the structured exercise program only for 12 consecutive weeks.
Interventions
The CL-AEx group completed a 12-week, moderate-intensity aerobic training program in addition to the structured exercise regimen. The aerobic component was performed three times per week at a fixed intensity of 65% of the maximum age-predicted heart rate for 45 minutes per session. Each session included a 5-minute warm-up and a 5-minute cool-down. The intensity and duration remained constant throughout the intervention period.
The G-AEx group completed a 12-week aerobic training program that progressively increased in intensity and duration, in addition to the structured exercise regimen. Sessions were conducted three times per week. The program commenced at an intensity of 50% of the maximum age-predicted heart rate for 25 minutes. Parameters were increased every two weeks, culminating in an intensity of 75% for 50 minutes during the final two weeks. Each session included a standard 5-minute warm-up and 5-minute cool-down.
The structured exercise regimen was conducted three times per week for 45 minutes per session over 12 consecutive weeks. Each session consisted of flexibility exercises, progressive resistance training, balance training, and low-intensity conditioning activities.
