- 1Plyometrics is an exercise used to develop ... in muscle groups? (1)Power (1)
- 2What two types of muscle contractions with plyometrics use? (2)Concentric (1) Eccentric (2)
- 3What is the receptor called within a muscle? (1)Muscle spindle (1)
- 4What is the purpose of the muscle spindle? (2)Detect the stretch of a muscle and the rate of stretch (1), when stretch or rate is too high and muscle Is in danger, the muscle spindle tells brain to contract muscle (2) to avoid injury, creating an eccentric muscle contraction (3)
- 5Describe the process of the stretch shorten cycle (3)Step 1 - stretching of muscle stimulates muscle spindles (1), Step 2 - activation of sensory neurone (2), Step 3 - informing processing at motor neurone (3), Step 4 - activation of motor neurone (4), Step 5 - contraction of muscle (5)
- 6What are the three phases of plyometric movements? (3)Eccentric (1), amortisation (2), concentric (3)
- 7Explain the eccentric phase of the plyometric movement (2)As an athlete lands the muscle in the legs are working eccentrically to slow the athlete down (1), the muscle spindle detects the muscle stretch (2), to avoid damage it contracts the muscle (3), this slows us down it also stores energy (4)
- 8Explain the amortisation phase and the concentric phase (4)Amortisation - a short phase when our muscle is not getting longer or shorter (1), the shorter the phase, the more power is stored (2)
Concentric - a concentric contraction against gravity (3), the muscle gets shorter using the power (4), this is the performance movement (5) - 9What are the positives and negatives of plyometric training? (5)Positives - increase power (1), strengthen tendons (2), increase flexibility (3), improved muscle elasticity (4), improved response time (5)
Negatives - chance of injury (6), pre conditioned strength needed (7), change in surface properties (8), needs specialist coaching (9) - 10PNF was originally developed as a method of rehabilitation allowing athletes to regain...? (1)Lost flexibility after injury (1)
- 11Why is PNF different from other stretching? (1)Works by manipulating the body's protective measures (1)
- 12Where is the Golgi tendon organ and what is it's purpose? (3)In the tendon (1), when tension is high in a muscle the GTO will relax the muscle to avoid injuries (2), this will cause the muscle to stretch more (3), we use isometric contractions to cause this (4) When our muscle is stretched but contracting the GTO will relax the muscle, we use the relaxed muscle time to stretch further (5). When the muscle relaxes, we call it autogenic inhibition (6)
- 13Explain the hold relax type of PNF stretch? (3)Partner holds stretch at mild discomfort for 10 seconds (1), partner applies force against athlete and athlete resists creating isometric contraction for 6 seconds (2), athlete relaxes and partner pushes slightly beyond ROM for 30 seconds (3)
- 14Explain the contract-relax-antagonist-contract PNF? (3)Hold athlete in mild discomfort for 10 seconds as they contract against hold (1), relax as partner pushes past ROM (2), begin to assist by pulling in the same direction as partner pushes (3), complete for 30 seconds
- 15What is meant by periodization? (1)Planning training to maximize performance in relation to a series of goals
- 16If you train continuously for maximum intensity you are likely to ...? (1)Plateau (1)
- 17Periodization requires goal setting, what are the goals broke into? (3)Macrocycles (overall goal) (1), mesocycles (2), microcycles (3)
- 18What does a microcycle consist of? (2)Small aspect of training, they generally last 5-10 days (1) and contribute to mesocycles, they are usually training plans covering a week representing training in a pattern such as legs then arms on alternate days (2)
- 19What is meant by tapering? (1)Reducing training load prior to competition (1)
- 20What is meant by peaking? (1)Ensuring that mind and body are at optimal performing condition at the time of competition (1)
- 21What is the method of periodization and explain it? (3)Wave like method (1), a period of high intensity followed by low intensity (2), allows athlete to avoid overtraining (3) and recover before a period of high intensity leading to competition (4)
