you become inspried by all the knowledge you have gained during the HSC 303 course and decide to start a running program.
why when you stop running does it take a while for your breathing to return to normal:
post exercise oxygen consumption
repay oxygen debt: oxygen taken in above resting values after exercise
O2 becomes available, binds to H+ ions and clears lactate
how long till all physicolgical systems return to normal? 24 hrs
how long till intramuscular PCr and ATP are restored? 2-3 minutes

susan is a 35 y/o Female who began an exercise program 6 months ago in which she has been running on the treadmill 4/week. answer the following questions based off of this scenario.
susan has noticed that her resting heart rate has dropped due to her training. what are the likely changes she has seen in resting cardiac output?
No change - because of increased stroke volume
susan is a 35 y/o Female who began an exercise program 6 months ago in which she has been running on the treadmill 4/week. answer the following questions based off of this scenario.
after six months of training what adaptations would be seen in susan's heart?
increased size in L ventricle wall
susan is a 35 y/o Female who began an exercise program 6 months ago in which she has been running on the treadmill 4/week. answer the following questions based off of this scenario.
she is now planning on running a half marathon. Design a training program to help her increase her lactate threshold, allowing her to finish the race under 2 hours.
tempo training- increase lactate threshold and structure accordingly
discuss the likely causes for msucle fatigue during exercise.
o2 deficitif you dont have o2, you wont have glycolysis
no glycolysis, no aerobic metabolism
lactate build upincreased H+ ions
increased acidity
decreased neuromuscular activity
in musclesdecreased Ca2++ release in SR, so less muscle contraction.
depletion of muscle glycogen

discuss the cardiovascular adaptions that take place with prolonged endurance training and how these factors might influence VO2max
increased L ventricle wall
increased stroke volume
decreased HR
increased blood plamsa
increased O2 to skeletal muscles
more blood flow, so all of these will increase peak vo2
