Is elastic fantastic? Impact of elastic inserts on rein tension assessed

reins-stockClear differences in the tension applied by riders between normal reins and those with elastic inserts have been identified by researchers, who have sounded a note of caution.

Elastic has been used over the years to achieve “give” and flexibility in equestrian equipment such as girths and reins.

The reins provide a physical means for the delivery of signals / aids from the human to the horse.

Rein design with the inclusion of elastic inserts are designed to “diffuse tension, to avoid pressure on the horse’s mouth and to avoid sustained tension on the reins”.

However, researchers found that this design can have a substantial impact on the tensions applied, particularly when making transitions during equitation.

A study entitled, “Is elastic fantastic? The impact of elastic inserts on rein tension”, was conducted by researchers Dr Hayley Randle and Alison Abbey, from Duchy College, in Cornwall, England.

Their findings were presented at the recent International Equitation Science Conference in Demark.

The pair set out to determine the effect of elastic inserts in reins on, first, the tension applied for normal riding and a walk to halt transition, and second, the ability to release the tension in the reins.

Thirty female riders rode horses with either standard rubber or rubber reins with elastic inserts.

Rein tensions were measured using a Centaur rein tension gauge for left and right hands, with both rein types when taking up a normal riding contact and executing a walk to halt transition.

The results of the study showed significantly different tensions were applied by riders with the two types of rein.

Lower tensions were exerted on reins with the elastic insert than with the rigid reins in the normal riding contact condition, whilst higher tensions were evident with elastic insert reins than with rigid reins in the walk to halt transition.

rein-tensionThe time taken for rein tension to return to zero following complete release by the rider was significantly greater, and less consistent, with the elastic insert reins than with the rigid reins.

Since sustainable and ethical equitation relies upon the effective delivery and receipt of clear signals and timely pressure-release; rein tension and pressure-release should be used carefully and consistently in training.

The study suggests that although elastic inserts in reins may result in less tension in general riding, they may alter riders’ behaviour in terms of the tension applied when executing a particular equitation task.

Furthermore, elastic inserts in reins may have a harmful effect on a rider’s ability to apply negative reinforcement accurately and therefore clarity during training.

The impaired ability to simultaneously release pressure may have a negative impact on equine learning and training, and consequently equine stress and welfare.

Further research was needed into the incorporation of materials such as elastics, the researchers concluded.
