Background: Numerous studies have analyzed changes in biochemical blood parameters in ultra-endurance events but never in a kayak and cycling ultra-endurance event. Research question: The objective of this study was to analyze blood biochemistry changes in creatine kinase, urea, triglycerides, haemoglobin, creatinine, creatinine clearance and lactate in a 20-hour ultra-endurance kayak and cycling event. Type of study: Descriptive field study. Methods: The parameters of creatine kinase, urea, triglycerides, haemoglobin, creatinine, creatinine clearance and lactate were measured in 16 subjects (mean ±SD age 28.0±3.4 years; height 176.0±5.5cm; body mass 71.8±9.2kg) who participated in an ultra-endurance event before, and at the end of the race, in which they covered 100km in a kayak and 65km on a mountain bike. Results: Significant changes were observed (p<0.05) between the pre- and post race samples in the variables: creatine kinase and urea, but not between those of haemoglobin, creatinine, creatinine clearance, triglycerides and lactate. Conclusions: A 20-hour kayak and cycling race caused an increase in protein catabolism and muscle breakdown, but did not affect the subjects' renal function.
