USAGE OF SLOW-TWITCH MUSCLES

Most of the muscles are made up of two types of muscle fibers. These muscle fibers help you move your body. One of them is slow-twitch muscle fibers. They move more slowly but help to keep you moving longer. “Twitch” refers to the contraction, or how rapidly and often the muscle moves. Slow-twitch muscle fibers are all about endurance or long-lasting energy.

What are slow-twitch muscles?

Slow-twitch muscles have lots of blood vessels and minicells that produce energy called mitochondria. This helps to keep them going for long periods of time.

Slow-twitch muscles are aerobic muscles. This means that they use oxygen to generate energy in the form of ATP from their high concentration of mitochondria. As long as you get oxygen, they can keep you going.

Some of their features are –

• Use energy at a slow speed and somewhat equally enough to make it last for a long period of time. This helps them contract (work) for longer time periods, without any shortage of power.
• Fuel low-intensity activities for they need a steady supply of energy.
• Muscles with more slow-twitch fibers have a greater number of blood vessels. This is because they need a good and constant supply of blood as well as oxygen. This enables them to work for a long period of time without getting tired.
• Since they use an aerobic energy system, they run on oxygen.
• The bigger blood supply in slow-twitch muscles fibers can make them look redder or darker.

Which are slow-twitch muscles?

In your body, most of the muscles have more than one kind of muscle fiber. But some muscles have more slow-twitch fibers. This is because they have to do the same job for a long period of time.

For example, the muscles in the back of your lower legs and the muscles in your back are mostly made up of slow-twitch fibers. This is because they have to help you stand and hold your posture for long periods of time.

Types of activities that use slow-twitch muscles

Whenever you’re doing an activity or exercise that needs muscles to work — or even stay still — for a longer time period, your slow-twitch muscle fibers are working hard. These activities include sitting up, standing, walking, slow jog, running a marathon, biking, swimming laps, rowing, many yoga positions, and some pilates exercises.

What are the benefits of slow-twitch muscles?

Slow-twitch muscles are great for endurance exercises such as cycling and swimming
Slow-twitch “aerobic” exercises are generally called “cardio” exercises since they’re good for the health of the heart. They’re also good for toning your muscles.

Conclusion

Slow-twitch muscle fibers help you move or stay steady at one positionfor longer. Since they use oxygen as a source of energy, they need a rich supply of blood. This is exactly why slow-twitch muscle fibers are also called “red” muscles.
