Specialised Training Quiz What is the name of the specialised receptors that detect overstretching? What types of muscle contraction occur during the downward and upward phase of plyometric training? Describe a plyometric exercise that would improve the power of the quadriceps. What does PNF stand for? Name the sensor which causes the muscle to relax during PNF?

6. Briefly describe the process of using PNF for a hamstring stretch. 7. Briefly describe how altitude training is thought to improve endurance? 8. Name the 3 phases of training at altitude. 9. Describe 2 arguments against altitude training. 10. Name the process of boosting carb levels that many marathon runners use prior to an event.

11. Periodisation involves breaking down a training programme into separate parts. Name the 3 periods used. 12. Define tapering and peaking. 13. What does RER stand for? 14. How does RER provide a coach with knowledge of the energy source being used during exercise? 15. Name the process of measuring the levels lactic acid in blood to determine exercise intensity.

Answers Muscle spindles Isotonic eccentric then isotonic concentric Any appropriate bounding, jumping or hopping exercise Proprioceptive neuromuscular facilitation Golgi tendon organ Stretch to limit, hold for 10s, contract for 5s, stretch further, repeat. Increase number of RBC due to adaptation needed at lower partial pressure of oxygen. Acclimatisation, primary training, recovery Benefits don’t last very long, can’t train at same intensity, takes long time, expensive, altitude sickness, stressful. Glycogen loading (carbo loading) Macrocycles, mesocycles, microcycles. Tapering: reducing training prior to competition. Peaking: making sure that both mind and body are at their best for competition. Respiratory exchange ratio When fat is the major fuel RER will be a small number (as lots of 02 is being used) when carbohydrate is the major fuel RER will be high (less 02 required). Lactate sampling
