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.
This double-blind placebo controlled study will randomize adult survivors of childhood cancer who are 18 to 44 years of age, greater than ten years post first cancer diagnosis, and with low lean muscle mass to two groups: Resistance Training + Supplement (RT+S) or Resistance Training + Placebo (RT+P). Randomization will be stratified by sex and age (18-29 and 30-44 years) in a block size of 4. Three weekly resistance training sessions will occur over a 24 week period. The participants, investigator, trainer and individuals involved in testing will be blind to group assignment.
Participants will receive information about physical activity and its health benefits. They will be randomly assigned to one of two groups to receive individually tailored resistance training three times per week for 24 weeks. One group will receive a protein supplement, while the other group will receive a sports drink (placebo).
To assess outcomes, participants will have the following research tests:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Supplement Group | Active Comparator | Participants 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 Comparator | Participants 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Educational handouts | Other | Both groups of participants will receive educational handouts that explain the Physical Activity Guidelines for Americans at enrollment. |
|
| Measure | Description | Time Frame |
|---|---|---|
| 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. |

| Resistance training | Other | 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. |
