Outcome Measures

Primary Outcomes (2)

  • Change in strength in breast cancer survivors

    Participants will be evaluated for knee extensor strength via isometric maximum voluntary contraction at approximately 60° knee flexion.

    From baseline to 12 weeks

  • Change in functional capacity in breast cancer survivors

    Functional exercise capacity will be assessed via the 6 minute walk test (6MWT).

    From baseline to 12 weeks

Secondary Outcomes (2)

  • Change in intramuscular creatine and altering energy storage.

    From baseline to 12 weeks

  • Change in muscle cross sectional area

    From baseline to 12 weeks

Study Arms (2)

Creatine Supplement Group

EXPERIMENTAL

Participants will engage in three center-based exercise sessions each week for 12 weeks; each session lasting roughly 1-hour. Participants will be given a fitbit (electronic watch that measures steps or heart rate) as well to track heart rate and monitor activity throughout the study.

Dietary Supplement: Creatine

Exercise Only Control Group

NO INTERVENTION

Participants will not participate in the creatine intervention (creatine supplementation). Participants will engage in three center-based exercise sessions each week for 12 weeks; each session lasting roughly 1-hour. Exercise sessions will be held by trained study staff held at the Medical Arts and Research Center Physical Therapy clinic (address listed above).

Interventions

CreatineDIETARY_SUPPLEMENT

Those randomized to receive creatine (experimental group) will be initially dosed at 20 g/day for 7 days to boost availability of creatine systemically. Thereafter, the dose will be reduced to 5 g/day for maintenance through the duration of the 12-week protocol.

Model Details: This study plans to enroll 30 breast cancer patients who have completed chemotherapy within 6 months prior to consenting for this study. Patients eligible to participate in this study will be allocated to either the creatine group or the control group (1:1) based on a pre-determined randomization list. Each arm will have 15 participants. One arm will receive creatine and the other will serve as the control group with no creatine.
