Module 2-Chapters6-10 Flashcards
(20 cards)
Define Concentric movement.
Shortening of muscle against resistance.
Define Eccentric movement.
Lengthening of muscle against resistance.
What are the 3 types of Muscle contractions during open-chain resistance training?
Isometric, Isotonic, and Isokinetic
Define Isometric
Constant length, tension developes with no movement.
Define Isotonic
Same or constant tension.
Define Isokinetic
Speed of muscle contraction is controlled by a machine.
Define Power
The rate at which muscles work.
Define Muscle Strength
The maximum force that a muscle or muscle group can exert during a contraction.
Define Endurance
The ability of the muscle or muscle group to sustain contractions repeatedly or over a certain period of time.
Selection of appropriate “training” response is based on what 5 principle?
1) Sequential reorganization of neurophysiologic parameters
2) Skill transference
3) Performers attention focus
4) Feedback (frequency, bandwidth, delay, concurrent, terminal.)
5) Training, Practice, Treatment design structure.
What are the 3 fiber types?
1) Slow oxidative (SO)
2) Fast oxidative glycolytic (fatigue resistant)
3) Fast glycolytic (fast fatigable)
Muscle performance is?
Strength, Power, and Endurance.
In the geriatric population, what is the preferred sequence to performing open-chained exercises?
Isometrics, eccentrics, then concentric.
What is the safest mode of exercise for young children?
Open-chain
What are Type 2 muscle fibers?
Fast stretch muscle fibers that generate tension in a shorter period of time: fatigue quickly.
What does DOMS stand for?
Delayed Onset Muscles Soreness
What is the “Sliding filament Theory?”
It states that the sliding of Actin past Myosin generates muscle tension and causes contractions.
Define Hypertrophy.
Increase in muscle fiber size.
Define Hyperplasia.
Increase in muscle fiber numbers.
What are Type 1 muscle fibers?
Slow twitch fibers that sustain muscle tension over a prolonged period of time: slow to fatigue.
