Brief Summary
This study is being conducted because low lean muscle mass is prevalent among childhood cancer survivors. Lean muscle is the non-fatty muscle tissue that makes up part of the body's lean body mass. Low lean muscle mass is associated with loss of overall body strength, declining mobility and eventually, loss of independence. Among childhood cancer survivors, low lean muscle mass may contribute to reduced physical functioning and a sense of fatigue with exertion, limiting ability to participate in adequate physical activity. Loss of strength and a sense of fatigue with repeated movement make it difficult to participate in daily activities. Although there have not been exercise intervention studies among childhood cancer survivors specifically designed to evaluate the effects of resistance training on muscle mass, studies among individuals with chronic disease, including survivors of adult onset cancers, indicate that resistance exercise improves muscle mass, muscle strength, mobility, vitality and physical activity levels. Resistance training (weight lifting) is a form of physical activity that is designed to improve muscular fitness by exercising a muscle or a muscle group against external resistance. The purpose of the study is to evaluate the effects of resistance training combined with either a protein supplement or a sports drink on changes in lean muscle mass in young adults who were treated for childhood cancer. The sports drink, for this study, is considered a placebo.

Outcome Measures
Primary Outcomes (15)
Change in lean muscle mass by arm
Dual x-ray absorptiometry (DEXA) will be used to determine lean muscle mass. Fat free mass will be measured in the total body scanning mode.
Baseline and at 24 weeks
Change in handgrip by arm
Handgrip strength will be evaluated with a hand held dynamometer.
Baseline and at 24 weeks
Change in knee extension by arm
Knee extension strength will be evaluated with the Biodex System IV dynamometer.
Baseline and at 24 weeks
Change in ankle dorsiflexion by arm
Ankle dorsiflexion strength will be evaluated with the Biodex System IV dynamometer.
Baseline and at 24 weeks
Change in walking speed by arm
Usual walking speed will be evaluated by having participants complete a timed 10 meter walk test.
Baseline and at 24 weeks
Change in endurance by arm
Endurance will be evaluated by having participants complete the six minute walk test in a level of corridor as outlined by the American Thoracic Society.
Baseline and at 24 weeks
Change in activity level by arm
Participants will complete the physical activity monitor (PAM) component of the most recent release of the National Health and Nutrition Examination Survey to measure activity levels. The PAM collects information on intensity and duration of common activities like walking and jogging for seven consecutive days. Participants will receive an accelerometer with written instructions, programmed to begin recording 12:01 a.m. on the day after the baseline assessment (the week before they begin training) and the day after their final training appointment.
Baseline and at 24 weeks
Change in blood pressure by arm
Blood pressure will be evaluated with a sphygmomanometer.
Baseline and at 24 weeks
Change in high density lipoprotein by arm
High density lipoprotein will be evaluated from fasting blood samples as part of a standard lipid panel.
Baseline and at 24 weeks
Change in triglycerides by arm
Triglycerides will be evaluated from fasting blood samples as part of a standard lipid panel.
Baseline and at 24 weeks
Change in abdominal obesity by arm
Abdominal obesity will be evaluated by measuring waist circumference with a Gulick tape measure to the nearest mm.
Baseline and at 24 weeks
Change in fasting glucose by arm
Glucose level will be measured from fasting blood samples.
Baseline and at 24 weeks
Change in fasting insulin by arm
Insulin level will be measure from fasting blood samples.
Baseline and at 24 weeks
Change in C-reactive protein by arm
Highly sensitive C-reactive protein will be measured from fasting blood samples.
Baseline and at 24 weeks
Change in self-reported exhaustion by arm
Measured using the vitality subscale of the Medical Outcomes Survey Short Form-36 (SF-36), version 2.
Baseline and at 24 weeks

Supplement Group
ACTIVE COMPARATORParticipants will receive educational handouts and complete research testing to evaluate their physical condition prior to beginning the resistance training and dietary supplementation. Adherence will be assured as described below.
Placebo Group
PLACEBO COMPARATORParticipants will receive educational handouts and complete research testing to evaluate their physical condition prior to beginning the resistance training and placebo. Adherence will be assured as described below.
Interventions
Both groups of participants will receive educational handouts that explain the Physical Activity Guidelines for Americans at enrollment.
Individuals in both groups will participate in an individually tailored progressive resistance training program 3 times/week for 24 weeks. During weeks 1-4 participants will be supervised twice a week tapering to once a week in weeks 5-12, every other week in weeks 13-20 and then once a month in weeks 21-24 by an American College of Sports Medicine (ACSM) Certified Exercise Specialist (trainer). Adherence: To assure fidelity and safety of the resistance training component of the intervention, participants will initially be supervised more frequently They will complete an exercise log for each of their sessions. As the supervision level for exercise is tapered, participants may receive reminders to exercise and take their supplement/placebo via text, phone, or e-mail as needed.
A medical quality protein supplement powder will be mixed with water or a sugar free drink mix to be taken daily within 60 minutes of training on exercise days or mid-morning on non-exercise days.
A placebo that appears to be identical to the medical quality protein supplement powder will be mixed with water or a sugar free drink mix to be taken daily within 60 minutes of training on exercise days or mid-morning on non-exercise days.
