THE EFFECT OF AN ENDURANCE SWIMMING SESSION ON CLARA CELL PROTEIN AND CRP CONCENTRATIONS IN ELITE AND RECREATIONAL ENDURANCE MALE SWIMMERS

The presence of epithelial cells in the blood is a symptom of cellular damage.
Clara's cell proteins are the epithelial cells of the lungs and the respiratory tract, also, the existence of
cytokines such as reactive protein C is a sign of inflammation. The purpose of the present study was to
investigate the effect of one session of endurance swimming activity on the serum concentration of Clara
proteins and reactive protein C in elite male swimmers.
Materials & Methods: The present study was a semi-experimental research with two stage pretest and
posttest design. 20 male swimmers (BMI 23/55±1/22 kg/m2, Height 174±9/12 cm, Weight 61/35±5/65
kg, fat 19/19±2/4 percent, Elite: 10 male, recreational: 10 male) participated in this study. Clara cells
and reactive protein C were measured after a session of endurance activity with an intensity of 70-75%
of maximum oxygen consumption for 30 minutes. Data were analyzed by repeated measures analysis
of variance (P≤0/05).
Results: Statistical analysis showed that Clara's serum concentration increased significantly in both
groups of elite and recreational swimmers after training intervention (p=0.001). Also, reactive protein
C increased significantly (p = 0.003). The results of the comparison of the mean posttest for Clara cell
and the reactive protein C of the elite and recreational groups showed that there was a significant
difference in the amount of Clara cell protein (p = 0.001), and the amount of C-reactive protein
(p=0.002).
Conclusion: It seems that a session of endurance activity of the swimming-pool causes a sharp increase
in the serum levels of Clara proteins and CRP in elite and recreational male swimmers, although the
history was not intended
