How do trainers of professional supercross racers use this data to make their workouts more sport specific?
The knowledge of this competition data gives the trainer or athlete a starting point to design effective training programs using heart rates. They would use different training programs like interval training and cycling to accomplish their goals. This type of training would get the athlete in shape to the fitness level necessary to maintain heart rate levels similar to those experienced during actual race condition. For example, if a racer recorded his heart rate during training (cycling or on the track) so that it was kept above the average heart rate during a 20 minute main event and could sustain that rate for say 30 or 45 minutes (after working up to that time over a period of weeks) without fatiguing or laying down slower lap times they should theoretically be able to perform during a race with much less effort. This would decrease their chance of fatigue and or perceived exertion. This data can be used as a gauge to determine a racers fitness level as compared to the average prof
