Principles, Science and Training Methods

 It is not enough to know how to ride; you must know how to fall.

Spontaneity isn’t random. . . . How good people’s decisions are under the fast moving, high stress condition of rapid cognition is a function of training and rules and rehearsal.

On average riders have about ¾ of a second (ranging from ½ second to about 1 second) to respond in a fall incident.

Average adult SRT is about 200 ms

RT = Reaction Time + Movement Time

Emergency Response Action

250 ms (React)* + 250 ms (Brace) = 500 ms *(once the rider realises they are falling)

RT = Reaction Time + Movement Time

Movement time = 250 ms

SUMMARY

There is no time for conscious analysis and evaluation of alternative courses of actionThere is time for trained response actionResponse action can be quick once trainedResponse Time will improve with training

Expectancy(warning signals) Bertelson (1967) found that

where there was a warning of 100 to 200 ms, reaction time was quicker than when there was no warning.

In an unexpected fall incident, additional time is needed (up to 200 ms) to change the focus of attention from “riding” to “falling”

Rider response time, after training, is estimated to be on average 500 ms where there is some warning signal that the rider may fall and 700 ms where the rider has no warning signal. Allowing for individual and situational differences, this is expanded to a range of values ±100 ms.

Hanging onto the Reins

• Not all falls can be practiced but the advantage of training is to make some behaviour second nature – crucial when there is only a split second to react.

• There is a tendency to hold on to the reins when falling. . . these images demonstrate potentially dangerous consequences for the rider.

Tumbling at SpeedNewtons First Law of Motion

A body at rest will remain at rest or a body in motion will remain in motion unless acted upon by an external force.Benefit of Tuck and roll: Some of the force is spent on the rolling the length of time to come to rest is increased, and forces of impact are drastically reduced with arms in brace position the forces of impact can be diverted away

from the head and neck

Muscle tension to stay in tuck position, and arms in brace position to protect the head and neck

IMPORTANT SAFETY NOTE:

• A number of basic exercises, drills and skills can be practiced by riders unsupervised.

• Other skills must be learned under the supervision of a qualified fall safety instructor.
