Abstract

Background: Triathletes have an extremely high rate of injuries during training and competition. Studies vary from 50% -90% injury rate each year. Most studies find that the injuries most often occur during running (50%). This study and all other studies have been done in the laboratory setting, none of the studies were completed outdoor where competition typically take place.

Objective: The study analyzed the mechanics of triathletes during the bike-run transition and during the run following it to determine if there are biomechanical changes during training. Drone technology using GPS guidance will be used to follow the triathlete during this process to document the running mechanics.

Methods: This descriptive pilot case series recorded 3 triathletes while training for a triathlon. A drone followed the participants and recorded the biomechanics during a 5k run to get a baseline for their run, then they biked a 40k then finished with another 5k run.

Results: Significant differences in the hip angle, specifically the pelvic tilt, in 2 out of 3 triathletes. Subject 1 was p< .03, subject 3 was p< .01. There was a difference in subject 2 but it was not a significant level.

Conclusion: The biomechanical analysis showed a significant difference in anterior pelvic tilt during the run after the bike training. This has a significant impact on the stress in the lumbar-pelvis and lower lumbar areas, thus predisposing the triathlete to injuries to these areas.
