Resistance Training Program and Cardiovascular Exercise in Increasing Muscle Mass in Adolescent and Young Adult Stem Cell Transplant Survivors

PRIMARY OBJECTIVES:

I. Determine the feasibility of a 12-week resistance training (RT) intervention in adolescent
and young adult (AYA) hematopoietic cell transplant (HCT) survivors starting +100 days
post-HCT.

SECONDARY OBJECTIVES:

I. Examine the change from baseline of a RT intervention on muscle strength and body
composition at day +200 and day +365.

II. Determine the effectiveness of RT exercise on improving the cardio-metabolic risk factor
profile at day +200 and day +365.

III. Determine the effectiveness of RT exercise on improving quality of life (QOL) measures.

IV. Compare day +80 and day +365 assessments to subjects in a historical control population.

OUTLINE:

Patients undergo moderately intense aerobic/cardiovascular exercise over 30-60 minutes and
complete 1-2 sets of 8 to 10 resistance/strength training exercises, 8 to 12 repetitions of
each exercise, 3 days per week for 12 weeks. Patients also participate in weekly phone calls
with an exercise physiologist to ensure adherence to the program and to provide support.

After completion of study intervention, patients are followed up within 2 weeks, then at 365
days post HCT.

Inclusion Criteria:

- > 80 days but less than <120 days post-autologous or allogeneic HCT for a hematologic
malignancy.

- Platelet transfusion independent.

- Fully mobile on an independent basis.

- For patients who have been on steroid therapy for graft versus (vs) host disease,
doses of prednisone must be =< 0.5 mg/kg/day and they must be on a tapering schedule.

- English speaking.

Exclusion Criteria:

- Individuals who are determined by the investigators or primary treating physician to
not be physically able to participate in an independent exercise intervention such as
hospitalized, wheel chair bound, unable to ambulate independently, on oxygen.

- Women who are pregnant will be excluded.
