Extra calories can be provided in the form of fat (oil) for performance horses that are prone to PSSM. Since PSSM1 is an autosomal dominant trait, there is at least a 50% chance of passing the causative mutation to each offspring. The most common breed affected by PSSM is the Quarter Horse, followed by the Draught and Warmblood breeds. Its likely an old genetic mutation that occurred prior to the foundation of most modern horse breeds. McCue ME, Valberg SJ, Miller MB, Wade C, DiMauro S, Akmand HO, Mickelson JR. Glycogen synthase (GYS1) mutation causes a novel skeletal muscle glycogenosis. Horse Ownership, , For chronic cases, prolonged rest after an episode appears to be counterproductive and predisposes PSSM horses to further episodes of muscle pain. This build-up of glycogen interferes with the muscle cells ability to contract and relax, which can lead to muscle stiffness, cramping, and weakness.

The effect of exercise on glucose clearance in horses with polysaccharide storage myopathy. A recent study did not find a significant association between the commercial genetic test variants P2, P3 (a and b), and P4 and horses with a diagnosis of PSSM2 or MFM based on histopathology (the gold standard for evaluation of muscle disease). Approximately 11% of quarter horses are affected by PSSM1.

Many exercise studies have proven that this is absolutely not the case with PSSM. One is to feed a diet that is high in calories and low in carbohydrates. Muscle conditions affecting sport horses. The beneficial effect of the low starch, high fat diet is believed to be the result of less glucose uptake into muscle cells and provision of more plasma free fatty acids for use in muscle fibers during aerobic exercise.
