Abstract
The purpose of thjs study is to detem1ine the effects of an acute
bout of exercise on sa)jvary lactoferrin responses among smokers and non·
smokers. Eighteen sedentary men were recruited; nine smokers (age = 22.4
± 1.4 years; BM1 = 22. I ± 1.1 kglm2) arul nine non-smokers (age = 22. 1 ±
0.7 years old; BM1 = 22.5 ± 1.9 kg!m2). In this study, participants cycled at
an intensity of 60% tnaxjmum heart rate for 60 minutes. Pamcipants were
given cool water as much as 3 ml!kg body weight at minutes 20 and 40
during the exercise session. Participants' body weight and saliva samples
were collected at pre and post-exercise. Heart rate and rate of perceived
exertion (RPE) were recorded at pre, during and post-exercise. Mixed
ANOVA was used to measure significant differences between groups and
within group. The resuJts showed that sa)jva flow rate, lactoferrin
concentration and lactoferrin secretion rate were not significantly di!Terent
(p>O.OS) between smokers and non-smokers groups and also between pre
and post-exercise withjn each group. Heart rate and RPE showed
significant increased (p<0.05) during the exercise session in both groups.
As a conclusion, acute bout of exercise docs not affect salivary lactoferrin
responses among sedentary smokers and non-smokers men.
