They get their name from the &#8216;twitching&#8217; movement they produce when they contract.\u00a0<\/span><span style=\"font-weight: 400;\">There are two types of twitch muscle fibers: fast-twitch and slow-twitch. As you might expect, each type of fiber has its own unique set of characteristics (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4315934\/\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">). <\/span><span style=\"font-weight: 400;\">Fast-twitch muscle fibers are used for activities that require quick, explosive movements, such as sprinting or jumping. They contract more quickly than slow-twitch muscle fibers, but they also tire more quickly. <\/span><span style=\"font-weight: 400;\">Slow-twitch muscle fibers are used for activities that require sustained muscle contraction, such as long-distance running or cycling. These contract more slowly than fast-twitch muscle fibers, but they can do so for a longer period of time before fatigue sets in. <\/span><span style=\"font-weight: 400;\">Both types of fibers are important for overall fitness and performance. You can train each type of fiber differently to improve your results. Read on to learn more about fast-twitch and slow-twitch muscle fibers, and how you can benefit from training both.<\/span><\/p>\n<a

But the distribution of these fibers varies from person to person. And this can impact your athletic performance. There are a few ways to determine if you have more fast-twitch or slow muscle fibers.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Activity_Level\"><\/span><strong>Activity Level<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you&#8217;re a highly active person, chances are you have more fast-twitch muscle fibers. That&#8217;s because these fibers are better suited for the explosive activities that require quick bursts of energy. For example, power athletes have a higher ratio of fast-twitch to slow-twitch <a href=\"https:\/\/betterme.world\/articles\/high-knees-benefits\/\">muscle fibers<\/a> (<\/span><a href=\"https:\/\/www.mdpi.com\/2075-4663\/9\/9\/127\/htm\"><span style=\"font-weight: 400;\">6<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, if you&#8217;re not very active, you&#8217;re likely to have a 50\/50 distribution of fast-twitch and slow-twitch muscle fibers. But if you lead a sedentary lifestyle, you may have a higher percentage of slow muscle fibers.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Genetics\"><\/span><strong>Genetics<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Your genes also play a role in determining the distribution of fast-twitch and slow-twitch muscle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">According to research, the type of <a href=\"https:\/\/betterme.world\/articles\/wood-chop-exercise-benefits\/\">muscle fibers<\/a> you have is mostly determined by your genes (<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/7649409\/\"><span style=\"font-weight: 400;\">3<\/span><\/a><span style=\"font-weight: 400;\">). So if your parents were endurance athletes, you&#8217;re likely to have more slow-twitch muscle fibers. And if they were power athletes, you&#8217;re likely to have more fast-twitch muscle fibers.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Age\"><\/span><strong>Age<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">As you age, the number of fast-twitch muscle fibers in your body decreases. That&#8217;s because these fibers are more susceptible to damage, wear and tear. Furthermore, loss of lean muscle mass is a natural part of the aging process (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4414960\/\"><span style=\"font-weight: 400;\">1<\/span><\/a><span style=\"font-weight: 400;\">) (<\/span><a href=\"https:\/\/academic.oup.com\/biomedgerontology\/article-abstract\/50A\/Special_Issue\/11\/597813?redirectedFrom=fulltext&amp;login=false\"><span style=\"font-weight: 400;\">4<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As you get older, you&#8217;re likely to have more slow muscle fibers.

This type of training increases your body&#8217;s ability to sustain prolonged effort. It enables your muscles to use oxygen more efficiently and resist fatigue for a longer period of time (<\/span><a href=\"http:\/\/link.springer.com\/10.2165\/00007256-200232080-00002\"><span style=\"font-weight: 400;\">12<\/span><\/a><span style=\"font-weight: 400;\">).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Endurance training can be performed through a variety of activities, including running, cycling, rowing, and swimming.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some of the key characteristics of endurance training are:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Low_Resistance\"><\/span><strong>1.

They get their name from the 'twitching' movement they produce when they contract.\u00a0<\/span><span style=\"font-weight: 400;\">There are two types of twitch muscle fibers: fast-twitch and slow-twitch. As you might expect, each type of fiber has its own unique set of characteristics (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4315934\/\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">). <\/span><span style=\"font-weight: 400;\">Fast-twitch muscle fibers are used for activities that require quick, explosive movements, such as sprinting or jumping. They contract more quickly than slow-twitch muscle fibers, but they also tire more quickly. <\/span><span style=\"font-weight: 400;\">Slow-twitch muscle fibers are used for activities that require sustained muscle contraction, such as long-distance running or cycling. These contract more slowly than fast-twitch muscle fibers, but they can do so for a longer period of time before fatigue sets in. <\/span><span style=\"font-weight: 400;\">Both types of fibers are important for overall fitness and performance.
