This trial aims to evaluate the impact of exercise intensity on cardiac health in young adult survivors of childhood cancer previously treated with anthracyclines.
This phase 1, pilot, randomized clinical trial aims to evaluate the impact of exercise intensity on cardiac health in young adult survivors of childhood cancer previously treated with anthracyclines. Participants will be randomized into 1 of 2 study groups: Arm 1: High-intensity interval training (HIIT) or Arm 2: moderate intensity continuous training (MICT). The research study procedures include screening for eligibility, in-clinic visits, questionnaires, measurements of height, weight, waist, and hip circumference, blood pressure, cardiopulmonary fitness, activity measurements, blood tests, and electrocardiograms (ECGs). Participation in this research study is expected to last about 4 months. It is expected that about 20 people will take part in this research study.

Change in average E/e' ratio
Average E/e' ratio assessed by echocardiography using Doppler methods per ASE/EACVI guidance. E is the early diastolic transmitral inflow velocity (pulsed-wave Doppler) and e' is early diastolic mitral annular tissue velocity (tissue Doppler); average e' is typically the mean of septal and lateral e'. Reported as change from baseline to post-intervention.
Time frame: Baseline (Week 0) and post-intervention (Week 17)
Change in septal mitral annular e' velocity
Septal e' velocity measured by tissue Doppler imaging at the septal mitral annulus. Reported as change from baseline to post-intervention. Units: cm/s (or m/s).
Time frame: Baseline (Week 0) and post-intervention (Week 17)
Change in lateral mitral annular e' velocity
Lateral e' velocity measured by tissue Doppler imaging at the lateral mitral annulus. Reported as change from baseline to post-intervention. Units: cm/s (or m/s).
Time frame: Baseline (Week 0) and post-intervention (Week 17)
Change in left atrial maximum volume index (LAVImax)
Maximum left atrial volume indexed to body surface area (mL/m²) measured by 2D echocardiography (e.g., biplane method of disks). Reported as change from baseline to post-intervention.
Time frame: Baseline (Week 0) and post-intervention (Week 17)
Change in peak tricuspid regurgitation velocity
Peak tricuspid regurgitation (TR) jet velocity measured by continuous-wave Doppler. Reported as change from baseline to post-intervention. Units: m/s.
Time frame: Baseline (Week 0) and post-intervention (Week 17)
Change in left ventricular global longitudinal strain (LV GLS)
LV global longitudinal strain measured by 2D speckle-tracking echocardiography (typically averaged across LV segments from apical views). Reported as change from baseline to post-intervention. Units: %.

Change in VO₂max
Change in peak oxygen uptake (VO₂max) during a graded cycle cardiopulmonary exercise test (CPET), reported as VO₂max (mL/kg/min), derived from expired gas analysis (averaging interval per prespecified CPET analysis approach).
Time frame: Baseline (Week 0) and post-intervention (Week 17)
