Section 6 Flashcards
What are the main energy systems?
Creating phosphate, lactate and aerobic
What energy rich compound can be identified as our main energy currency?
ATP
Describe how energy is released from ATP.
It is released when one of its high energy bonds is broken.
What is the main energy system employed by sprinting?
Creatine phosphate
Which energy systems require no oxygen?
Creatine Phosphate and Lactate
How are Creatine phosphate stores replenished?
Liver and kidney produce Creatine phosphate from amino acids or he body takes on dietary Creatine primarily from eating meat and fish.
Approximately how long does it take the body to replenish Creatine phosphate stores?
5 minutes rest
For how long can the lactate system sustain activity?
60-180 seconds
Give an example of an athletic event that relies on the lactate system.
400m
Which energy system is dominant during lower intensity activities?
Aerobic system
Which energy system results in the incomplete breakdown of carbohydrates?
Lactate system
Which energy system involves the complete breakdown of carbohydrates and fats?
Aerobic system
The use of which energy system can result in the characteristic “burning” sensation in muscles?
Lactate system
What are the byproducts of the aerobic energy system?
Carbon dioxide, water and heat
Give 3 examples of training adaptations achieved through aerobic training?
1) Pulmonary
2) Cardiovascular
3) Muscular
