When you have made your notes please add the key notes to the blog.
Your notes will be used to initiate discussion during wednesdays lesson.
i) Restoration of muscle glycogen stores during lactacid/alactacid EPOC recovery
ii) Effect of exercise and recovery on muscle myoglobin
iii) Buffering, removal, recycling and oxidation of lactic acid
iv) Sources of energy for exercise - i.e. carbo-loading
v) Reasons for ergogenic aids (drugs/supplements – CP ingestion).

"v) Reasons for ergogenic aids (drugs/supplements – CP ingestion)."
is what u wrote, but surely its supposed to be CO INGESTION and not cp?
brusk
im baffed?!
is it CP or CO ?????
brusk
Definately CP - Creatine and Phosphates suppliments. How
What is CO?
i think he means the effects of taking creatine, protein and other supliments.
is the first thing about the question from the test that i didnt understand?

carbo-loading aims to prevent the onset of fatigue during endurance events.carbo-loading can almost double the normal amount of stored carbohydrate found in a trained person. it also means reducing training load and resting the muscles to allow them to become completely loaded with glycogen.
ergogenic is a substance used for the purpose of enhancing performance by improving energy production, energy control or energy efficiency.
oxygen is essential for the production of energy by aerobic processes. The greater the body's capacity to supply oxygen to the muscles during exercise, the greater the ability to maintain aerobic activity without fatigue. If a person can improve their capacity to utilise oxygen they are likely to improve their performance in endurance events.
To increase the oxygen carrying capacity of the blood some athletes train at higher altitudes where the air contains less oxygen. The body then adapts to the shortage of oxygen by increasing the number of red blood cells. When the athlete returns to sea level the increased oxygen carrying capacity of the blood should enable the athlete to push harder and faster.
Caffeine is a performance enhancer as it is a central nervous system stimulant and has been used by some athletes as an ergogenic aid in endurance exercise. Caffeine does not seem to benefit short-term high intensity exercise.
epoc- the alactacid component, often refered to as fast replenishment and involves the restoration of atp and phosphocreatine stores.
the lactacid component- this is concerned with the removal of lactic acid, this is a slower process. lactc acid can be removed in some ways.1, oxidation into carbondioxide and water.2,conversion into glycogen,then stored in the the muscle/liver.3,conversion into protein or glucose.
Excellent stuff salih.
Have a go at the other aspects of lactic acid - i.e. buffering and recycling.
Also check out the importance of muscle myoglobin and how it differs from haemoglobin and what happens once it has reached the mitochondria.
Let me know if you can't find anything meanful and I will push you in the right direction. Brian mac is always a good starting point.
good stuff.....
Thanks Todd, thats exactly what I meant!
Come on brusk...tell us what CO means!
myoglobin is a protein substance used as the primary oxygen-carrying pigment of muscle tissues. It is the substance which gives muscles their red appearance. With increased activity in muscles, their myoglobin stores are said to increase. http://www.nature.com/nature/journal/v171/n4363/abs/1711069a0.html
