Lecture 3 Flashcards
1
Q
Aerobic Power
A
rate of energy release by oxygen-DEPENDENT metabolic processes
2
Q
Maximal Aerobic Power
A
maximal capacity for aerobic resynthesis of ATP
- aka: aerobic capacity, maximal O2 uptake, VO2max
- primary limitation: cardiovascular system
3
Q
Anaerobic Power
A
rate of energy release by oxygen-INDEPENDENT metabolic processes
4
Q
Maximal Anaerobic Power
A
maximal capacity of anaerobic systems to produce ATP
- aka: anaerobic capacity
- maximal accumulated O2 deficit test
- critical power test
5
Q
Stretch Shortening Cycle
A
active stretch of a muscle during an eccentric contraction followed by an immediate shortening (concentric) of the muscle (i.e. coming out of the hole during a squat)
6
Q
Rate Coding
A
frequency of impulses sent to a muscle (i.e. twitch, summation, tetanus)
- increases with resistance training (rapid movement, ballistic type training)
- increased force can be generated through increase in either the number of muscle fibers recruited or the rate at which the impulses are sent
7
Q
Delayed Onset Muscle Soreness (DOMS) (5)
A
- results primarily from eccentric action
- associated with damage or injury within muscle
- may be caused by inflammatory reaction inside damaged muscles
- may be due to edema (accumulation of fluid) inside muscle compartment with in turn activates pain receptors
- is felt for 12-48 after exercise
8
Q
Normal Intrinsic Inhibitory Mechanisms (Autogenic Inhibition)
A
- Golgi tendon organs
- inhibit muscle contractions if if tendon tension is too high
- prevents damage to bones and tendon
9
Q
Training can _________ inhibitory impulses (Autogenic Inhibition)
A
decrease.
- muscle can generate more force
- may also explain superhuman feats of strength
