Answer 1

Можна, м’язи запам’ятовують багато нового, якщо їх тренувати вони зміняться

Answer 2

Can training change the ratio of slow and fast fibers in a muscle?

The ratio of slow and fast fibers in a muscle is primarily determined by genetics and cannot be significantly altered through training. Slow-twitch (Type I) muscle fibers are more resistant to fatigue and are better suited for endurance activities, while fast-twitch (Type II) muscle fibers generate more force and are used for explosive movements. The proportion of these fibers in a muscle is largely determined by an individual's genetic makeup.

While training can lead to adaptations within muscle fibers, such as increased size and improved efficiency, it does not fundamentally change the ratio of slow and fast fibers. Training can, however, enhance the performance and capabilities of the existing fibers.

It's important to note that the specific training regimen can influence the recruitment and activation of different muscle fiber types. For example, endurance training, such as long-distance running, tends to activate and develop slow-twitch fibers, while resistance training, such as weightlifting, can stimulate the growth and strength of fast-twitch fibers. However, these adaptations do not change the underlying ratio of slow and fast fibers in the muscle.

In conclusion, while training can lead to improvements in muscle performance and adaptations within muscle fibers, it does not significantly alter the ratio of slow and fast fibers in a muscle. The genetic makeup of an individual plays a major role in determining the proportion of these fiber types in the muscle.
