Well that hypertrophy is concentric, which means that the new sarcomeres are generated in parallel with existing ones.

肥大是向心性的，这意味着有新肌产生，与之前的肌平行生长。

Its their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax.

正是它们对钙和三磷酸腺苷的使用导致了使肌和放松的结合和松弛。

A muscle contracting is all about sarcomeres contracting, bringing those Z-lines closer together.

肌就是肌，使这些 Z 线更靠近。

In the process, it shrinks the whole sarcomere, and contracts the muscle.

在这个过程中，它会整个肌，肌。

Both those features--myomeres and notochords--are found only in chordates.

这两种特征——肌和脊索——仅存在于脊索中。

The fossils revealed distinctive, zig-zag-shaped muscles, known as myomeres, which are still present in fish today.

这些化石展示了独特的、呈之字形的肌，即肌， 这种结构至今仍然存在于鱼类中。

For skeletal muscles, improved flexibility comes from additional sarcomeres, which allow you to maintain strength at even greater lengths.

对于骨骼肌， 增加的柔韧性来自于额外的肌，这使您可以在更长的距离内保持力量。

They're divided lengthwise into segments called sarcomeres, which contain two even tinier strands of protein — two different kinds of myofilaments called actin and myosin.

它们在纵向上被分成称为肌的部分，其中包含两股更小的蛋白质——两种不同的肌丝称为肌蛋白和肌蛋白。

At the smaller scale, these skeletal muscle fibers are comprised of millions of sarcomeres— the smallest contracting unit of muscle tissue.

在较小的尺度上，这些骨骼肌纤维由数百万个肌组成——肌组织的最小单位。

A sarcomere contains both thin filaments, made up mostly of two light and twisty actin strands, and thick filaments, composed of thicker, lumpy-looking myosin strands.

肌既包含细丝，主要由两条轻盈而扭曲的肌蛋白链组成，也包含粗丝，由更厚、看起来块状的肌蛋白链组成。

Sarcomeres are added and subtracted to muscles depending on how frequently they're used, so improving overall flexibility requires a comprehensive stretching regimen.

肌的增减取决于肌的使用频率，因此提高整体柔韧性需要全面的拉伸方案。

You might be able to piece a guess together by the shape, color, bones, and myotomes which are the little meat squiggles you see on the fish.

你可以根据鱼的形状、颜色、骨头以及中那些小条纹（肌）来拼凑出一个猜测。

Sarcomere's long, fibrous proteins can relax to elongate muscle fibers or they can contract to shorten them— pulling on tendons and protective tissue to create the force propelling our athlete's body.

肌的长纤维蛋白可以放松以拉长肌纤维，也可以以短它们——拉肌腱和保护组织以产生推运员身体的力量。

Immediately after a muscle fiber is stimulated by a nerve — when calcium ions are flooding into the sarcomeres to pull away those two protein bodyguards of tropomyosin and troponin from the actin — that's called the latent period.

肌纤维被神经刺激后立即——钙离子涌入肌，将肌蛋白中保护原肌蛋白和肌钙蛋白的蛋白质带走——这称为潜伏期。
