Purpose: The inflammatory markers cause changes in body composition and endocrine activity and lead to
cardiovascular disease and diabetes. The aim of present study was to determine the comparison the effects of 12
weeks of morning and evening aerobic training . Method: this study was of type Quasi – experiments, 40 nonathletes,
obese men were randomly allocated to four groups of morning and evening aerobic training and morning
and evening control. Morning and evening training groups performed the aerobic training protocol three sessions per
week for 12 weeks with 75 to 85 percent of maximal heart rate and 15 minutes training per session. The training
time was increasingly added 1 minute every two session until the training time reached to 30 minutes .while the
control groups were denied doing training programs during the research period. Blood samples (5 cc) were taken
from the participants at the beginning of the period, week 6 and end of week 12 in order to measure C-reactive
protein (CRP), interlukin-6 (IL-6) and tumor necrosis factor-alpha (TNF- α). Statistical analysis of the data was
performed using the 4× 3 factorial ANOVA with statistical process was done using SPSS software, version 15, and
the significance level was considered P<0.05Results: The results showed that morning and evening aerobic training
decreased CRP and IL-6 in the experimental groups compared with the control ones. Also, the amount of produced
inflammatory markers was less in the evening than in the morning (in the evening training group, the amount of
CRP was 17.1%, 10.5% and 18.87% in week 1, week 6 and week12 and the amount of IL-6 was respectively 21.5%,
16.74% and 25.32% lower than that of the morning training group). level of TNF-α decreased in the experimental
group mor than control group after 6 and 12 weeks of training, Although this change was not
significant..Conclusion: According to the results of this study, it was determined that different times of the day
influence the compatibility of inflammatory markers caused by aerobic training and these markers show more
reduction in the evening. Therefore, it is recommended to young obese men to do exercises in the evening rather
than morning.
