Group 5- Muscle fibre types by https://padlet.com/patrick_license/taqei80pffln Matt's assignment en-us 2017-10-19 12:24:25 UTC 2017-10-20 11:47:24 UTC hello@padlet.com Fast twitch callum_hancock https://padlet.com/patrick_license/taqei80pffln/wish/198621186 fast twitch muscle fibers are used for short periods of maximal intensity work. but these types of muscle fibers fatigue easily and they are used for short bursts powerful movement e.g. sprinting. there are two types of fast twitch muscle fibers, there is fast-oxidative fibers and fast-glycolytic fibers.

advantages -  it allows us to work aerobically for longer periods of time, this helps us to do things such as run, swim, cycle and walk for long periods of time. 

disadvantages - if your in a sport that requires both fast and slow twitch fibers then if a defender only has slow twitch then they wont be able to catch a striker sprinting to score a goal.

sporting disciplines associated slow twitch - long distance running, swimming, cycling and walking are examples of this.]]> 2017-10-19 12:39:50 UTC https://padlet.com/patrick_license/taqei80pffln/wish/198623286 fast-glycolytic fibers callum_hancock https://padlet.com/patrick_license/taqei80pffln/wish/198627600 this type of muscle fiber is better suited to anaerobic activity. These fibers contract rapidly causing them to fatigue easily, this is why they are suited to anaerobic work. This type of muscular fiber is used in high intensity and short periods of work. the main reason why these are important with in physical activity is because they allow a quick change in pace, for example- a foot baller when they have to use a short burst of power to either jump and head the ball or even just and injection of pace in order to chase back an opposition player. ]]> 2017-10-19 12:48:57 UTC https://padlet.com/patrick_license/taqei80pffln/wish/198627600 References patrick_license https://padlet.com/patrick_license/taqei80pffln/wish/198628507

fast-oxidative fibres are used for aerobic metabolism, and are able to use either glucose or fats as a source of energy which means that if you havent eaten for a long time they can still work well. 
it last longer than glycolytic fibers when it comes to aerobic fitness so it is more use fell for sports such as rugby.

you wont be able to last a whole match just using these type of fibres because you need to move around a lot
doesn't contract as quick the glycolytic fibres
