There are many different types of body muscles. Among these different body muscles, some of them work involuntarily. Of these muscles, theskeletal musclesare the muscles that move bones, limbs and the body in general. These skeletal muscles have two general types of fibers. Namely, they are the slow twitch fiber (type I) and fast twitch fiber (type II). Generally, a human body contains a relatively equal amount of these two fibers. However, it is not surprising to note that sprint runners in Olympics have almost 80% of fast twitch fibers and marathon runners have almost 80% slow twitch fibers that aid them in their events. It is because we have different percentage makeup of slow and fast twitch fibers in our bodies due to our genetics. Therefore, even if you want to be a runner, whether that suits you depends on your fiber makeup on the basis of your genetics.

What are Slow Twitch Fibers?
Slow twitch fibers (type I) are a type of muscle fibers that contracts slowly. These fibers help in long endurance heats such as distance running since they are resistant to fatigue. Furthermore, these fibers are very efficient in utilizing oxygen for cellular respiration and in the production of ATP. For these purposes, slow twitch fibers have more线粒体.
As they can hold oxygen efficiently, they can produce energy easily without causing a buildup of lactic acid. Also, these fibers have great endurance despite being weak. Athletes running marathons make good use of these fibers to run long distances. Moreover, red fiber is another name for these fibers due to their color. That is; because of the high amount of blood-carrying myoglobin, they get this darker appearance.
什么是快速抽搐纤维?
快速抽搐纤维是一种迅速收缩的肌肉纤维。由于这些纤维可以在短时间内产生更多的能量,因此它们有助于诸如冲刺之类的强大爆发运动。因此,它赋予了他们额外的力量,他们变得活跃和爆炸性。但是,他们很容易变得疲倦。简而言之,当力需求较高时,它们比缓慢的抽搐纤维更快,身体会募集或激活快速的抽搐肌肉纤维。但是,只有在缓慢的抽搐纤维无法满足力需求时才发生。
此外,快速抽搐纤维以白色出现,因为它们不含太多血液。因此,它们的外观比缓慢的抽搐纤维更轻。此外,快速抽搐纤维有两种类型。也就是说,它们是快速的IIA和快速交换型IIB。
What are the Similarities Between Slow and Fast Twitch Fibers?
- 缓慢和快速的抽搐纤维是两种类型的骨骼肌纤维。
- 两种类型都产生能量并帮助运动。
- 而且,两者都产生力。
- Furthermore, both types of fibers are present relatively in equal amounts in the human body.
What is the Difference Between Slow and Fast Twitch Fibers?
Slow twitch fibers are the muscle fibers that help long endurance while fast twitch fibers are the muscle fibers that facilitate powerful movements while having least endurance. Therefore, this is the key difference between slow and fast twitch fibers. Based on the endurance capacity, long-distance runners have a relatively high amount of slow twitch fibers while short distance runners who engage in sprinting etc., have a relatively high amount of fast twitch fibers.
A further difference between slow and fast twitch fibers is that the slow twitch fibers do not fatigue faster while the fast twitch fibers fatigue faster. Moreover, the capacity to hold oxygen is another difference between slow and fast twitch fibers. That is; the slow twitch fibers can hold more oxygen for cellular respiration than the fast twitch fibers.

摘要 - 缓慢与快速抽搐纤维
Slow and fast twitch fibers are two types of skeletal muscle fibers. Slow twitch fibers contract slowly and are somewhat weaker muscle fibers. On the other hand, fast twitch fibers contract very quickly and are strong fibers. Hence, this is the key difference between slow and fast twitch fibers. Furthermore, the slow twitch fibres appear in red since they have a greater capillary density while fast twitch fibers appear in white since they have a very low capillary density. Also, slow twitch fibers are highly resistant to fatigue; hence, do not become tired quickly.
另一方面,快速抽搐纤维更快地疲劳,因此很容易疲倦。此外,缓慢的抽搐纤维有助于长时间耐力,而快速抽搐纤维的耐力较低。此外,快速抽搐纤维涉及强大的运动,因为它们可以在短时间内产生大量的力。但是,缓慢的抽搐纤维的线粒体比快速的抽搐纤维更多。以上是缓慢和快速抽搐纤维之间差异的摘要。

I suspect males have a higher ratio of fast twitch muscles than females or else sports records would show it in results!
