Eight cyclists were photographed with a digital camera for three trials while positioned on their own bicycle wearing their helmet. The positions were different from each other and described as hands on the brake hoods, hands below the curve of the brake hoods on the handlebars, and using aerobars. Twenty-four trials were digitized by two different individuals three times to estimate the inter- and intra-rater reliability of the method. The intraclass correlation coefficient (p less than 0.05) value for the intra-rater (test-retest) reliability was 0.993, and for inter-rater consistency, it was 0.976. There were significant differences (p less than 0.05) between digitizers and between trials, apparently due to a learning effect that disappeared by the third trial. Due to small differences between digitizers and trials, caution is recommended when considering the use of this method. (Contains 4 figures.)
