Feasibility of High Intensity Interval Training in Survivors of Childhood, Adolescent, and Young Adult Hodgkin Lymphoma

Overview

This pilot study evaluates the feasibility of a 12-week high intensity interval training (HIIT) program in survivors of childhood, adolescent, and young adult Hodgkin lymphoma within 24 months of completing treatment. Preliminary efficacy of the HIIT intervention for improved cardiorespiratory fitness, body composition, physical function, autonomic response to exercise, peripheral neuropathy, biological aging markers, and physical activity will also be evaluated. Primary Objective: To determine the feasibility of a 12-week high intensity interval training (HIIT) program in survivors of childhood, adolescent, and young adult Hodgkin lymphoma within 24 months of completing treatment. Feasibility will be assessed by: * Participation Rate: Number of eligible survivors approached who enroll. * Completion Rate: Number of scheduled HIIT sessions attended and number of enrolled participants who complete post-intervention testing.

Hodgkin lymphoma survivors face elevated risks of cardiovascular disease and premature aging. HIIT, which alternates high-intensity effort with recovery periods, has shown benefits in adult cancer survivors but has not been tested in younger populations. This study will assess whether recently treated survivors can complete a remotely supervised 12-week HIIT program and evaluate its effects on multiple health outcomes. Participants will undergo baseline and post-intervention assessments including exercise testing, body composition, autonomic function, and blood biomarkers. The intervention is delivered via a secure web-based platform with live supervision by exercise physiologists.
