š“ Conditioning 101 š
Horses have 3 types of muscle fibers.
1. Type 1 or the slow twitch. Responsible for posture, endurance, low intensity training. You build these by trail riding, water treadmill, and endurance riding. Horses like Arabians & Thoroughbreds can have a higher make up of type 1 & type lla fibers than other breeds.
2. Type IIa Fibers (Fast-Twitch Oxidative Fibers)
Hereās your middle of the road. These maintain power over a more extended period. Used more in dressage, eventing or distance racing.
3. Type IIx Fibers (Fast-Twitch Glycolytic Fibers)
Barrel racers this is you. This is your high intensity but short burst fibers like for sprinting. And you can probably guess that these occur at a higher rate in QHs.
Performance horses need cross training. Not just one single conditioning routine. Get out and do the long slow trail ride but if you want to be building those Type llx fibers you need to get out there and sprint some hills now and again to. š
