Interesting study that shows that leg boots and wraps can be more detrimental than helpful.
A client recently asked me if they should be using boots or polos on their horse. Many horse owners have the best intention in using boots or wraps to protect their horses legs from trauma during exercise and competitions. But many don’t realize that boots can essentially insulate the distal limb and prevent heat loss during exercise leading to increased temperatures that can reach damaging levels during maximal exertion.
A study from Middle Tennessee State University measured temperature increase during a specified exercise protocol with different types of leg protection. The study found that the reduced rate of heat dissipation a boot can cause can be detrimental to the superficial digital flexor tendon. They tested six different types of boots or wraps during exercise: a traditional neoprene boot, a perforated neoprene boot, a plant-based neoprene boot made of Stomatex, a cross-country boot, an elastic track bandage, and a fleece polo wrap.
The study found that the bare limb had the lowest temperature, all treatment temperatures were greater than the bare limb across all time points. The fleece polo wrap had the highest temperature and humidity. None of the treated limbs returned to baseline temperature and humidity after the 180-minute recovery period, and all treated limbs reached temperatures that negatively affect tendon cells. The study suggests that the use of boots and wraps during exercise impairs convection cooling, causing chronic microdamage to the tendon.
Riders must weigh the pros and cons, considering boot design, application and material permeability. No matter what boot you choose, the best way to protect your horse is to remove it immediately after exercises and stand your horse in an ice bath.
Ps. (Cold hosing and ice boots aren’t even half as effective. We can chat about that about that research in a future post ;))
