Hypothesis
Does the skiing quality score from the Connected Boot correspond to self-assessed carving ability in recreational skiers?
Conclusion
The study found a strong correlation between self-reported carving ability and the skiing quality score from the Connected Boot, particularly for female participants.
Supporting Evidence
- The average skiing quality score was 5.55, with female participants scoring lower than male participants.
- Self-reported carving ability decreased from 7.26 before the study to 6.98 after.
- Correlation between self-reported ability and skiing quality score was 0.52, indicating reliable results.
Takeaway
This study looked at how well recreational skiers can judge their own skiing skills compared to a special sensor's measurements, finding that women adjusted their self-assessment more than men after using the sensor.
Methodology
Participants skied with the Connected Boot sensor system and completed questionnaires to assess their skiing skills before and after the study.
Potential Biases
Technical difficulties with the sensor system may have affected data collection and participant engagement.
Limitations
The study's findings may be limited by the short duration of sensor use and the lack of standardized instructions for participants.
Participant Demographics
The sample included 16 female and 46 male participants, with ages ranging from 16 to 72 years.
