Abstract

Neutrophil numbers and function (oxidative burst) were assessed in peripheral blood and oral samples before and after prolonged exercise. Blood neutrophil count increased (∼3.5-fold, P < 0.001) and function decreased (30% ± 19% decrease, P = 0.005) postexercise. Oral neutrophil count (P = 0.392) and function (P = 0.334) were unchanged. Agreement between oral and blood neutrophil function responses to exercise was poor. These findings highlight the importance of studying neutrophils within various compartments/sample types.

On évalue le nombre et la fonction (poussée oxydative) des neutrophiles dans le sang périphérique et dans des échantillons de salive avant et après un exercice prolongé. Le nombre de neutrophiles sanguins augmente (∼3,5 fois, P < 0,001) et leur fonction diminue (diminution de 30 ± 19 %, P = 0,005) après l’exercice. Le nombre de neutrophiles salivaires et leur fonction ne varient pas : P = 0,392 et P = 0,334 respectivement. La concordance entre les réponses fonctionnelles des neutrophiles salivaires et sanguins à l’effort est faible. Ces observations soulignent l’importance d’étudier les neutrophiles dans les différents compartiments/échantillons. [Traduit par la Rédaction]
