Effects of an Acute Bout of Resistance Training on Leukocyte and Leukocyte Subset Response in Breast Cancer Survivors.

摘要

The purpose of this study was to examine the immune response to a single bout of moderate-intensity resistance training in breast cancer survivors (BCS). BCS (n=4) and healthy controls (n=8) completed an exercise session consisting of 3 sets of 10 repetitions at 70% of one repetition-maximum on leg press, lateral pull down, leg extension, and seated row performed in a circuit fashion. Blood samples taken at baseline, immediately post (0h post), 2-hours post (2h post), and 24-hours post (24h post) exercise were assessed for total leukocyte, granulocyte, lymphocyte, and monocyte cell counts. Percent change (%Δ) scores from baseline-0h post, baseline-2h post, and baseline-24h post were compared using mixed-model ANOVAs between groups and indicated that there were no significant differences between total leukocytes (p=0.560), granulocytes (p=0.239), lymphocytes (p=0.257), or monocytes (p=0.721) at any point. Results suggest BCS and controls exhibit similar immune responses to an acute bout of resistance training.
