A Low or High Physical Activity Level Does Not Modulate Prostate Tumor Tissue Protein Synthesis Rates.

Introduction: Physical activity level has been identified as an important factor in the development and progression of various types of cancer. In this study, we determined the impact of a low versus high physical activity level on skeletal muscle, healthy prostate, and prostate tumor protein synthesis rates in vivo in prostate cancer patients.

Methods: Thirty prostate cancer patients (age, 66 ± 5 yr; body mass index, 27.
