Abstract/OtherAbstract:
The purpose of the present study was to examine the acute effects of resistance training (RT) on CD4+ and CD8+ T lymphocytes apoptosis (annexin V+) and migration (CX(3)CR1). Twelve subjects performed two RT sessions (3 sets of 9 exercises) with 1min (Hyper-1) and 3min (Hyper-3) of rest-interval length between sets and exercises. CD4+ and CD8+ cells count displayed no change following Hyper-1 and Hyper-3. There was an increase in the percentage of CD4+ positive for annexin V+ and CX(3)CR1+ immediately after and 24h post Hyper-1. Percentage of CD4+ positive for annexin V+ increased 2 and 24h post Hyper-3, and decreased after CXCR1+ for the same time-points. There was an increase in CD8+ positive for annexin V+ and CX(3)CR1+ immediately after, 2 and 24h post Hyper-1 and Hyper-3, while no differences were found between Hyper-1 and Hyper-3. Acute RT increase the apoptosis and migration of CD4+ and CD8+ lymphocytes even 24h after exercise, with minimal effects of rest-interval length.
