More E-Trakka Innovation: Stride Length Captured During Workouts
Adding yet another dimension to understanding your horse’s performance, Etrakka has formally introduced the metric known as SL50 – stride length at 50kmh (31mph, or 14.8sec/furlong). The new GPS antenna also will allow you to view stride length at peak speed; something that is becoming ever more common at 2yo in training sales.
To date: several hundred measurements of SL50 have been taken ranging from 18-23ft, with the average score sitting right at 20 feet. As expected, elite horses average readings come in at just over 21.3 feet. How do your horses measure up?
This link takes you to some info from the manufacturer; including a neat comparison between 2 horses with identical HR/GPS responses to exercise – however a superior stride length made one a millionaire:
Some barns are looking for reasons to keep a handsome, well bred young colt – and yet others are looking to cull stock. Stride length can provide a valuable piece of information when making those difficult choices.
Bringing along some youngsters and hoping to avoid downtime due to shin soreness? Checking these figures during each workout is crucial – as you can catch the very first instance of a shortening of stride – as little as 1.5 feet, that can be one of the very first signs of problems. Perhaps you are then looking at 2 weeks of rest, as opposed to 2 months-
A while back someone had posted this link on my Facebook page about Stride Angle:
The great Secretariat was thought to have a stride length at peak speed of just over 25 feet, which may be larger than all the greats save Man O War – however the link above shows him to have a very large stride angle (110 degrees). Conversely, Seattle Slew had a small stride angle of just 88 degrees.
While some of the measurements featured here could be open to debate, the main point is that when you increase stride angle by 1 degree you improve stride length by 2%. Think shoeing, think massage work, think uphill gallops – all ways to increase power and range of motion – leading to an improved stride length – the Etrakka can help you quantify and analyze this variable during your conditioning regimens. Find out what is, and isn’t, working.
