Area of Science:

Human Factors
Motorcycle Safety
Thermoregulation

Background:

Riding motorcycles in cold climates is common in Northern Europe.
Cold hands can affect dexterity and reaction time.
Understanding the impact of cold on braking is crucial for rider safety.

Purpose of the Study:

To quantify the effect of cold hands on motorcycle braking performance.
To assess reaction time and motor control during braking tasks under cold conditions.

Main Methods:

28 students with prior motorcycle braking experience participated.
Braking tests were conducted at normal hand temperatures and after cooling hands.
Performance was measured by reaction time to a visual stimulus and lever actuation speed.

Main Results:

Cold hands significantly reduced the time to respond to the stimulus and grip the brake lever.
Digit extension and flexion times for braking were also significantly slower with cold hands.
Overall braking performance showed a marked decrement under cold conditions.

Conclusions:

Cold hands negatively impact critical motorcycle braking actions.
This impairment poses a potential safety risk for motorcyclists in cold weather.
Further research into protective gear and rider training for cold conditions is warranted.
