lab 2 intermittent vs continuous exercise

Question 1

what were the objectives of intermittent and continuous exercise lab?

Answer 1

• understanding how intermittent and continuous exercise work, and what systems are being used.
• understand which one used fatigue faster and why.
• understand the importance of blood flow during recovery of the exercise.

Question 2

1 = compare
2= contrast

compare and contrast the 2 subjects, who did the intermittent and continuous exercise?

Answer 2

compare.
- their is very little to compare bc the exercises are very different and are testing different things.
- duration in seconds in close in time.

contrast
- both subjects are using different energy systems.
- the intermittent exercise is pushing the subject to complete breakdown, where continuous is more of a partial breakdown.
- during the isometric bicep curl their is no work being done because the body is actually not moving, where the intermittent is producing over 17,000 J of work.

Question 3

what is the predominant fuel system being used during continuous and intermittent exercise?

Answer 3

continuous
- aerobic glycolysis is the system being used because their was lactate that was being slightly produced.

intermittent.
- creatine phosphate system is being used bc the lactate system is slowly taking over.

Question 4

during both exercises, fatigue begins to take place, which system is being used with fatigue during continuous and intermittent exercise?

Answer 4

continuous (bi-curl)
- anaerobic system is being used meaning that their is no oxygen is being used.
- CrP and lactate is what is causing fatigue to occur.

intermittent (bike)
- stored ATP is used right away.
- we move from stored ATP to aerobic glycolysis, as their is an increase in H+ protons.

Question 5

what are some key mechanisms for recovery of continuous and intermittent exercise?

Answer 5

intermittent
- regeneration of CrP during the recovery time on the bike.
- fatigue doesn’t occur as quickly bc more O2 is coming into the heart allowing for a better recovery time.

continuous
- not as aerobic as the bike.
- regeneration of ATP-CrP.

Question 6

how would creating more blood flow to the bicep, change this part of the lab? what would we notice?

Answer 6

• if we created more blood flow to the bicep then we would be bringing more O2 into that area allowing for a better recovery to occur.
