An observational analysis of climbing an obstacle in mountain biking: A case study.

This article focuses on the development and validation of an ad hoc observation system within observational methodology to analyze and intervene in the technical action of climbing an obstacle in mountain biking. Using data from an elite Enduro mountain biker, the study identifies four fundamental phases of the climbing technique—pedal stroke, handlebar pull, hip push, and stabilisation—detailing specific biomechanical and positional characteristics at the start and end of each phase. The observation instrument demonstrated high reliability and validity through intra-observer concordance (Cohen's Kappa) and generalisability analysis, and the findings provide a detailed model of ideal technique useful for coaches and mountain biking practitioners. This system offers a practical tool for improving obstacle climbing skills, complementing existing expert guidelines with empirical evidence from a professional athlete's performance.
