LectureNotes said the effect of training will be lost if the training is discontinued. Which principle of physical activity does it refer to?

Answer:

The statement “the effect of training will be lost if the training is discontinued” refers to the principle of reversibility in physical activity and exercise physiology.

Reversibility Principle

  1. Definition

    • The reversibility principle, also known as the “detraining effect,” states that the adaptations and improvements gained from systematic exercise and training will gradually be lost or diminished when the training stimulus is reduced or stopped.

  2. Explanation

    • When someone engages in consistent exercise or physical activity, physiological changes occur in the body, such as increased muscle strength, endurance, and cardiovascular efficiency. These adaptations are the result of progressive overload and regular training.
    • However, if the training stops or significantly decreases, these adaptations start to revert back to their pre-training states. For example, muscle strength and endurance decrease, aerobic capacity declines, and other fitness components regress.

  3. Implications for Training

    • To maintain the benefits of training, it’s crucial to engage in regular and consistent physical activity.
    • This principle emphasizes the importance of not only achieving a level of fitness but also sustaining it through continuous exercise. Even periods of reduced activity, often due to injury, illness, or other commitments, can lead to noticeable declines in fitness levels.

Examples

  1. Cardiovascular Fitness

    • After stopping aerobic exercise, VO2 max, which measures cardiovascular endurance, begins to decline within the first 1-2 weeks. Significant losses can occur within a few months.

  2. Muscular Strength and Endurance

    • Muscular strength starts to decrease after a few weeks of inactivity. Muscular endurance also diminishes, although the loss may be slower compared to cardiovascular fitness.

  3. Flexibility

    • Flexibility tends to last longer than cardiovascular or muscular fitness but will eventually decrease without regular stretching exercises.

Application

To counteract the reversibility principle, individuals should:

  • Include regular maintenance workouts in their routines.
  • Gradually reduce intensity or volume rather than stopping abruptly if needing to take a break from regular training.
  • Engage in cross-training or alternative activities that maintain fitness levels when specific activities are not feasible.

Final Answer:
The principle of physical activity discussed here is the reversibility principle.
