Competition Load Described by Objective and Subjective Methods During a Surfing Championship

Fernández-Gamboa I., Yanci J., Granados C., Freemyer B., Cámara J.

The aims of this study were to describe the competition load of surfers during a
single heat via objective and subjective methods and to analyze the relationship
between objective and subjective methods with the judges’ score. Ten
competitive surfers were fitted with a global positioning system (GPS) during a
competitive heat. The GPS was synchronized with a chronometer and a stationary
video camera to identify the surfer’s specific actions. After the end of each heat,
participants were assessed for the rating of perceived respiratory and muscular
exertion (RPEres, RPEmus) and also official scores from every participant were
collected. A very large significant relationship between wave riding distance and
respiratory perceived exertion heat load (RPEres HL, r =0.79; ± 0.26 CL p < 0 .01, 99.5/0.4/0.1, very likely) was found. Active time was also very large and significantly related to both RPEres HL (r = 0.75; ± 0.29 CL p < 0.05, 99.0/0.8/0.2, very likely) and muscular perceived exertion heat load (RPEmus HL, r = 0.83; ± 0.22 CL, p <0.01, 99.8/0.2/0.0, most likely). Very large significant correlation was obtained between the RPEres and score (r = 0.83; ± 0.22 CL, p < 0.01, 99.8/0.2/0.0, most likely). The subjective method seems to be a good instrument to assess the heat load of a surf competition. Wave characteristics seem to be an important factor in perceived exertion during competitive surfing.
