Why are some Greyhounds extremely explosive, that is to say, the speed is very fast, why are some Greyhounds not fast, but their endurance is particularly good, so they are suitable for running long distances?
these The reason is all determined by the musculature of the Gree dog. The Gree dog is actually doing two kinds of exercise when running: one is anaerobic exercise and the other is aerobic exercise.
The speed-up of the Gree dog is an explosive anaerobic exercise, that is, it exerts the maximum speed in a short period of time. This exercise usually only lasts for a few seconds. This exercise consumes A substance called creatine phosphate (ATP), creatine phosphate can directly supply the energy needed by the muscles, at this time, there is no need to add oxygen. However, creatine phosphate will be consumed in a few seconds, and the next exercise is aerobic exercise. Aerobic exercise can last for several hours. At this time, sugar (that is, starch) and fat in the body participate in oxidative conversion and convert into energy.
Gree dogs have different muscles and feel different. The muscles of dogs with good explosiveness are very soft, flexible, and feel like water. Such muscles are the most suitable for running, and they are not suitable for running. Easy to strain. The muscles of some Gree dogs are particularly strong, giving people a strong sense of beauty. It is true that everyone likes strong muscles, but hard muscles are the easiest to strain, and such muscles are not suitable for particularly vigorous running.
