Fusion


It is generally accepted that muscle fiber types can be broken down into two main types: slow twitch (type I) muscle fibers and fast twitch (type II) muscle fibers. Fusion is a way to train both slow and fast muscle fibres. We are going to play with tempo this week. If you want to learn a little about the muscle fibres, I have broken it down below.

Slow Twitch Muscle Fibbers (Type I)

The slow twitch muscle fibers are more efficient at using oxygen to generate more adenosine triphosphate (ATP) fuel for continuous, extended muscle contractions over a long time. They fire more slowly than fast twitch fibers and can go for a long time before they fatigue. Therefore, slow twitch fibers are great at helping athletes run marathons and bicycle for hours.


Fast Twitch Muscle Fibers (Type II)

Because fast twitch fibers use anaerobic metabolism to create fuel, they are better at generating short bursts of strength or speed than slow muscles. However, they fatigue more quickly. Fast twitch fibers generally produce the same amount of force per contraction as slow muscles, but they get their name because they are able to fire more rapidly. Having faster twitch fibers can be an asset to a sprinter since she needs to quickly generate a lot of force.


Cardio Monday is about shuttle runs and a Tabata workout, Saturday Parkmum Bootcamp is called Intervals of Destruction #parkmum #buggyfit #fusion #musclefibers #personaltrainer #primrosehill #regentspark #highgatewoods #postnatalexercise #postnatfitness #workoutfun
