在肌肉增长上更有优势 Genetic factors also play a role in one's ability to grow muscle. 基因因素也会影响肌肉增长 Some people have more robust immune reactions to muscle damage, 有些人对肌肉损伤有更强大的免疫反应, and are better able to repair and replace damaged muscle fibers, 更容易修复和...
If you imagine the cross-section of a muscle, you would see bundles of fibers known as fasciculi, which are surrounded by a connective tissue called the perimysium. Each fasciculi contains from 10 to 100 muscle fibers, depending on the specific muscle. A large, strong muscle, such as t...
A pulled muscle occurs when a muscle anywhere in the body is stretched beyond its means, leading to slight tearing of the tiny fibers that make up the muscle. A pulled muscle is sometimes known as a strained muscle, and the condition can be quite painful, though some instances of a ...

Fast twitch muscle fibers are tissues capable of creating intense but short bursts of power. Muscle tissue is generally broken down into two categories: fast twitch and slow twitch. Fast twitch fibers are sometimes called Type II muscle, and slow twitch fibers are known as Type I. Fast and ...
Fast-twitch fibers, also called white fibers or type II fibers, are skeletal muscles that help with power performance for short periods. Because so much power is used in a short time, these muscles become fatigued faster.1 Fast-twitch muscle fibers are also broken up into two types: type ...
Hyperplasia is the splitting of muscle fibers, resulting eventually in a greater number of fibers the same size as the originals. It has been said that the number of muscle cells one is born with is all they will ever have, and the splitting is not new fibers but damage to existing fiber...
How Are Muscle Fibers Different From Each Other? Not all muscle fibers are the same. There are two main types: slow-twitch (Type I) and fast-twitch (Type II), Andy explains. They differ in size, function, and where they get their energy, which makes each type suited to different kinds...
You damage your muscles during your workout. A few hours later, inflammatory chemicals invade your muscles, causing you to experiencemuscle sickness. This sickness challenges your immune system, which releases healing chemicals. Within a week, the process ends with rejuvenated muscle fibers. ...
In addition, your muscle fibers gradually change in response to your workouts. For example, intermediate type 2a fibers morph into type 2b fibers, which are the muscle fibers responsible for strength and size (2). It stands to reason that the longer and more consistently you train, the more...
