Final answer:
The Overload, Progression, and Reversibility Principles are essential in understanding how the body adjusts to training by managing stress levels effectively.
Explanation:
Overload Principle: The fitness principle states that a greater-than-normal stress load on the body is needed for the body to adjust to training. This principle suggests that the amount of stress applied during exercise must exceed a threshold level to stimulate adaptation, leading to improved fitness.
Progression Principle: This principle emphasizes the gradual and safe introduction of additional stress to improve fitness without risking injury or overuse. It focuses on progressively increasing the workload to continue challenging the body for adaptation.
Reversibility Principle: This principle highlights that adaptations to stress can be lost over time if training is modified or stopped. It underscores the importance of consistent training to maintain improvements achieved through exercise.
