Types of fibers

Types of fibers

Muscles generate ATP by cellular respiration
Glucose uptake
1. Glucose is one the primary energy sources
2. GLU channels are measured in intensity and will grow
Oxygen uptake
1. Maximum consuming of oxygen is called "maximum uptake"
  1. Expressed as: Vo(2) max
  2. Size, gender and age determine this
2. Means the quantity of O2 molecules used
3. Excercise means agitation and use of O2
  1. People breathe rapidly in order to pay the "oxygen debt"
Lactate threshold
1. Used to define the intensity of an excercise
Phosphocreatine
1. More ATP is used during excecise
2. Phosphocreatine in muscles is 3 times higher in number than ATP
Skeletic muscle fiber clasification
1. Type I: Slow contraction fibers
2. Type IIA: Oxidative glucolitic fibers of quick contraction
3. Type IIB: Glucolitic fiber of quick contraction
