Hypothesis

Can a peak detection algorithm and machine learning model effectively measure movement cadence and recognize cycling task changes in triathletes?

Conclusion

The study found that a custom peak detection algorithm and machine learning model are effective tools for automatically analyzing triathlon performance.

Supporting Evidence

  • The peak-counting algorithm detected 98.7% of swimming strokes and 97.8% of cycling pedal strokes.
  • The machine learning model was 94% accurate at distinguishing between 'in-saddle' and 'out-of-saddle' riding.
  • Participants were filmed while competing to ensure accurate data collection.

Takeaway

This study created a tool that helps triathletes measure their swimming, cycling, and running movements automatically, making it easier to improve their performance.

Methodology

Triathletes wore a trunk-mounted measurement unit while competing in a triathlon, and their movements were recorded and analyzed using a peak detection algorithm and machine learning model.

Potential Biases

The initial data collection had an overrepresentation of 'in-saddle' riding, which may have inflated the model's accuracy.

Limitations

The model could not distinguish between 'coasting' and 'in-saddle' riding, limiting the analysis of cycling motor skills.

Participant Demographics

12 triathletes (6 males, 6 females; mean age 16.2 years) with varying competition levels.
