fast and slow muscle fibres

• functions:

  fast = power (short term)

  slow = endurance (long term)
• production of ATP:

  slow - slow production of ATP

  fast - fast production of ATP
• respiration -

  slow - many mitochondria for aerobic respiration. Many capillaries. Less likely to fatigue

  fast - adapted for anaerobic respiration. fatigue quicker
• stores:

  slow - myoglobin, higher affinity to oxygen than haemoglobin (stores oxygen)

  fast - phosphocreatine, converts adp to atp
