Abstract:
Acute ultra-endurance cycling efforts may induce high amounts of oxidative and inflammatory stress among the cyclists and if the adaptation to neutralize these effects are insufficient or if the oxidative and inflammatory stress are excessive and uncontrolled, could lead for inflammatory damage to the bronchial epithelial tissue and also could cause for the temporary suppression of immune strength leading to easier infections from pathogens of the respiratory tract. Upper Reparatory Tract Infections (URTIs) may be seen common among the people involve in the high intensity ultra-endurance physical activities. Two groups of cyclists, one professional and the other recreational cycling groups participated in the study, with hundred male cyclists in each, in the age range of 23 to 35 years. WURSS-44 questionnaire was used to quantify the URTI symptom scores of the subjects and the FEV1was measured through digital spirometry for further analysis. The scores of the professional and recreational groups when analyzed indicated that there was significant difference both in in their URTI symptom scores and FEV1scores, the Pre cycling URTI symptoms scores of the Professional and Recreational cyclists were 19.54 and 41.88, whereas the Post cycling URTI symptoms scores were 29.56 and 58.27. Pre cycling FEV1 scores of the Professional and Recreational cyclists were 5.595 and 4.226, whereas the Post cycling FEV1 scores were 5.2986 and 3.903. Covariance analysis indicated both variables showed significantly different as the F value was 6.62 (P=0.010819) for URTI symptom score and for FEV1 was 39.48 (P=0.0001), and interaction for two-way factorial ANOVA was of 117.819, significantly high at P of <0.00. Acute ultra-cycling effort of the study brought significant reductions in the functional lung capacities of both the professional and recreational cycling groups of the study.
