Abstract
Summary: There is an inverse relationship between regular physical activity and concentration of serum inflammatory
markers, with variations in resting CRP in trained and untrained subjects. The effect of acute and prolonged exercises has
been studied on inflammatory markers with dearth of information and controversies on the resting serum values of high
sensitivity CRP (hs-CRP). Therefore, this study sought to identify and compare variations that occur in serum levels of high
sensitivity CRP in groups of sportsmen (6) and physically active untrained subjects. Eighty-one healthy male participants
made up of 21 untrained (control), 10 footballers, 10 athletes, 10 karates, 10 volleyballers, 10 basketballers, and 10
baseballers voluntarily participated in the study. Participants rested while in sitting position for about 30 minutes during
which blood pressures and heart rates were taken. 5 mls of venous blood was withdrawn from the antecubital vein of the
participants (aseptically) between 7:00 and 10:00 am into lithium heparin bottles following an overnight fast. The supernatant
was decanted and centrifuged at 3000 rpm, serum was collected and stored at -20ºC prior to biochemical assay which was
done with the use of enzyme linked immunosorbent assay (ELISA) kits for hs-CRP. Differences in the means within the
sporting groups were analysed using one-way ANOVA while the difference between the trained sportsmen and untrained
young adults was analysed using the independent T-test. Statistical significance was set at p < 0.05. The Mean ±SEM age,
weight, height, and BMI of the participants were 22.0±0.8 years, 64.1±2.2 kg, 1.74±0.3 m, and 20.6±0.2 kg/m2
respectively.
The resting concentration of hs-CRP (µg/ml) was 1.0±0.2 in the untrained, 2.6±0.7 in footballers, 3.6±2.1 in track athletes,
2.4±0.5 in basketballers, 2.2±0.5 in volleyballers, 2.4±1.3 in baseballers, and 1.7±0.5 in karate respectively. There was no
significant difference in the resting hs-CRP amongst the sporting groups, and in the sportsmen and untrained group. Resting
serum levels of hs-CRP falls within normal range, and varies insignificantly in groups of sports, and in sportsmen and
untrained young male adults. This may suggest that the types of sporting activities or participation in sports has no impact
on the resting serum hs-CRP.
