How to Measure. To measure your horse, have him stand square on a level surface. Hold the tape or stick so it is perpendicular to the ground and beside the horse so it is even with the top point of the horseâs withers. If you are using a proper measuring stick, lower the bar so it meets the top of the horseâs withers.
Both these traits can be measured. The muscle tissue can be biopsied and the heart measured with an ultrasound machine. The heart can also be measured with a heart rate monitor which tells you how hard a horse is working at a specific speed or workload. The GoPro Hero 3 Jockey Cam and HR monitors make a great pair. If a horse can maintain a high cruising speed and continue work out near the aerobic threshold then he would be an exceptional animal.
