types of muscle fibers

types of muscle fibers

1. fast type 2x

   • glucolitics
   • the fastest but the less effective
   • divides faster the ATP
     • ATP
       • is produced by cellular breathing
         • aerobic
           • produce more energy
         • anaerobic
           • produce less

2. Fast type 2a

   • oxidative and glucolitic
   • faster the slow type but not as fast as 2x

3. slow type 1

   • oxidative
   • slowest but effective
