Short term effects of excercise

• Lactic accumulation


  Muscles feel pain when tired. Muscle fatigue is a result of anaerobic respiration
• Breathing depth and rate increase


  More air per breath to oxygenate muscles
• Heart rate


  Bpm increases
• Stroke volume


  Blood pumped in each beat
• Amount of blood pumped by heart -increases with intensity in response to bodies demands


  Cardiac output
