Targeting supple & smooth adaptation of fast twitch oxidative muscle fibres
As horses progress (during a preparation) from paddock condition to race fitness, muscle fibres must adapt to the increasing demands made on them. When work steps up to _ pace, Fast Twitch Oxidative Fibres are recruited to provide the power. As with other body tissues these muscle fibres must be trained to enable them to store glycogen and to generate more mitochondria (the power houses of the muscle cell) to use glycogen. If work rate gets too far ahead of mitochondria production, muscles may lose suppleness.
Fast Twitch provides specific nutrients to assist mitochondrial formation, anti-oxidant vitamins, selenium to enable glutathione peroxidase production and magnesium to address the metabolism imbalance caused by calcium flux on the muscle cell wall. For horses positive to the GYS1 gene (PSSM), feed a diet with minimum starch, combined with Fast Twitch pellets. For best results, Fast Twitch should be used in conjunction with an exercise program that maximises the use of the Fast Twitch Oxidative fibres.
