Relationship between some immunological indexes and maximal oxygen pulse in active girls: effect of a bout of intense aerobic physical activity

The aim of this study was to determine the relationship between T lymphocytes (CD4, CD8), NK (CD56), CD4ﰠ ratio and maximal oxygen pulse among the active girls in response to an intense aerobic physical activity.
This semi-experimental study was conducted on 20-25 years old active women. To estimate maximal oxygen pulse and immune response parameters, GXT treadmill test was performed. In order to evaluate the immune system response to intense physical activity, blood samples were obtained at 3 times (before, immediately after and 2 hours after the exercise).
The T-CD4燩 and CD4ﰠ rations were significantly decreased after an intense aerobic physical activity (P The findings of this research showed that in active women the maximal oxygen pulse, as an indicator of the efficiency of the cardiovascular system, has strong relationship with some immune system parameters.
