Emotional reactions to cycle helmet use.

Area of Science:

• Sports Science
• Human Factors
• Cycling Safety

Background:

• Bicycle helmet safety benefits may be limited by risk compensation.
• Previous helmet use is a factor that could influence responses to safety interventions.

Purpose of the Study:

• To investigate if prior bicycle helmet use affects behavioral and physiological responses to helmets as a safety intervention.
• To test the risk compensation hypothesis in relation to bicycle helmet use.

Main Methods:

• A field experiment was conducted to measure cycling pace and psychophysiological load.
• Heart rate variability was utilized as a measure of psychophysiological load.

Main Results:

• Routine helmet users cycled slower and exhibited increased psychophysiological load after helmet removal.
• Non-helmet users showed no significant changes in cycling behavior or psychophysiological load post-intervention.
• Heart rate variability proved effective in assessing psychophysiological load in real-world cycling scenarios with low physical demand.

Conclusions:

• The findings suggest that risk compensation in response to bicycle helmet use may be influenced by prior helmet usage patterns.
• Routine helmet use might lead to altered risk perception and behavior when helmets are removed.
• Heart rate variability is a viable tool for psychophysiological load assessment in cycling research.
