exercise

• aerobic exercise takes place in the presence of oxygen
• anaerobic respiration happens in the absence of oxygen
• reaction of aerobic exercise

  glucose + oxygen --- energy + carbon dioxide + water carbon being a waste product
• reaction of anaerobic exercise

  glucose --- energy + lactic acid lactic acid builds up causing muscles to become tired
• excess post - exercise oxygen consumption

  amount of oxygen needed to recover from oxygen debt, enables lactic acid to be converted into glucose meaning we will continue to breathe deeper
• massages


  help prevent DOMS, reduces inflammation and increases blood flow meaning more oxygen delivery
• ice baths


  prevent DOMS, constricts blood flow so oxygenated blood can rush to the muscles and get rid of lactic acid, reduces swelling
• carbohydrates


  replace glycogen stores
• rehydration


  when we sweat we lose water and salt, prevents dehydration
• immediate effects of exercise - getting hot, sweating, increased rate of breathing, increased heart rate, having red skin
• short term effects - fatigue, nausea, aching muscles, cramp and DOMS
• long term effects - improved stamina, body shape may change, increase in size of heart (hypertrophy), lower resting heart rate (bradycardia)
• long term can build muscle, improve speed, cardiovascular and muscular endurance and improve speed
