__**1. Energy Systems**__
 * Discuss the main difference between the three energy systems.
 * Explain why some endurance athletes 'hit the wall' in the final stages of a marathon. What strategues would you suggest to minimise the chances of this happening?
 * Explain how fatigue occurs when using each of the three systems.

To prepare athletes well for their events, training is essential. However, the type of training and methods used depends on the type of movements, skill requirements and specific demands of the activity (Outcomes 2, p153). The four main types of training are:
 * 2. Types of Training:**

1. Aerobic training: - Continuous training - Fartlek training (or 'speed play') - Aerobic Interval training - Circuit training

2. Anaerobic training: - Anaerobic level

3. Flexibility training: - Static (stationary) - Ballistic (repeated movements/bouncing) - Dynamic (uses speed and momentum with movements) - Proprioceptive Neuromuscular Facilitation (PNF - a progressive cycle incorporating static stretch, an isometric contraction and a period of relaxation in the lengthened position).

4. Strength training.
