can strategize when and how much to eat and drink. Additionally, the nutritional requirements do not end with competition. Elite athletes train as they race. This means these cyclists know their nutritional requirements during a training session, and use this information to get the most from each training session.
SUMMARY
The introduction of the GPS to the world of cycling has greatly affected the way elite cyclists test and train. This technology alone does not add much benefit to training except for giving the cyclist a map to where he or she is going, or where he or she has already went. However, the combination of GPS with power analysis greatly enhances the cyclist’s ability to train more efficiently. These two metrics allow the cyclist to see how well he rides over certain terrain, which adds a new level of data analysis. The cyclist can work on these areas to increase physical fitness and efficiency. Additionally, the right analysis software presents the data in a format that allows the cyclist to make conclusions in order to make the proper adjustments in training. Being able to see how one performs on a portion of terrain speaks volumes. Finally, the cyclist can be better equipped with proper nutrition by calculating nutritional requirements to enhance performance. By using these technologies, elite cyclists can train in ways that are the most effective and efficient for their sport. ?
