  1. What is interval training?
    Interval training is simply alternating bursts of intense activity with intervals of lighter activity.
  2. What can interval training do for me?
    Whether you're a novice exerciser or you've been exercising for years, interval training can help you jazz up your workout routine. Consider the benefits:
  3. What is Endurance performance?
    Endurance performance is determined by the capacity of the athlete's heart to pump unusually large volumes of blood and oxygen to the muscles. This allows the muscles to achieve higher work rates before they outstrip the available oxygen supply, developing skeletal muscle anaerobiosis (a reduced oxygen content of the cells). Training increases 'cardiovascular fitness', especially by increasing the body's maximum capacity to consume oxygen (VO2 max). This effect results from an increased maximum capacity of the heart to pump blood (the cardiac output) and an enhanced capacity of the muscles to consume oxygen. These adaptations delay the onset of skeletal muscle anaerobiosis during vigorous exercise, thereby reducing blood lactate concentrations in muscle and blood at all exercise intensities above the so-called 'anaerobic threshold' and so allowing the exercising muscles to continue contracting for longer, at higher intensities, before the onset of fatigue. In addition, these changes increase the capacity of the muscles to use fat as a fuel during exercise, thereby enhancing endurance performance.
  4. Benefits of Interval training
    You'll burn more calories. You'll improve your aerobic capacity. You'll keep boredom at bay. You don't need special equipment.

  52. The Principle of Progression
    implies that there is an optimal level of overload that should be achieved, and an optimal time frame for this overload to occur. Overload should not be increased too slowly or improvement is unlikely. Overload that is increased too rapidly will result in injury or muscle damage. Exercising above the target zone is counterproductive and can be dangerous. For example, the weekend athlete who exercises vigorously only on weekends does not exercise often enough, and so violates the principle of progression.
  53. The Reversibility Principle
    dictates that athletes lose the effects of training when they stop working out. Conversely, it also means that detraining effects can be reversed when they resume training. In short, If you don't use it, you lose it. (1)

  70. How can interval training improve aerobic performance?
    This repetitive form of training leads to the adaptation response. The body begins to build new capillaries, and is better able to take in and deliver oxygen to the working muscles. Muscles develop a higher tolerance to the build-up of lactate, and the heart muscle is strengthened. These changes result in improved performance particularly within the cardiovascular system
