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

Background & Aims: 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.
