Alterações imunológicas e antropométricas induzidas por uma ultramaratona em Kayak. Um estudo de caso

Abstract: RESUMO Replicando um estudo anterior com o mesmo canoísta veterano, foram analisados, no sangue periférico, os valores de várias células da função imune, bem como algumas medidas antropométricas, antes e um, cinco e dez dias após uma ultramaratona (UM) em Kayak. As amostras sanguíneas foram obtidas em jejum, às 9 horas da manhã e, pelo menos, mais de 12 horas após o último momento de esforço. Foram medidos o número de leucócitos e o número e percentagens de linfócitos, monócitos, neutrófilos, eosinófilos e bas… Show more

“…This ratio has been used as a useful index which represents the relative distribution of the T lymphocyte subtypes 25 , suggesting that decrease in the CD4 + /CD8 + ratio may be associated with the suppression of the responsiveness of the T cells after exercise 26 30 , suggesting that the body is at potential status of alertness against external aggression, which tends to take the clinical meaning of the transitory decrease of the CD4 + /CD8 + ratio for granted. In the present study, it was verified that there was no statistically significant difference in the CD4+/CD8+ T lymphocytes ratio between two days before and immediately after the event; however, statistically significant increase of the CD4+/CD8+ ratio was observed between two days before and six days after the event ( figure 1E).…”
