Dora has recently started working on a research study that hypothesizes that people who have a defect in a specific gene may have a predisposition to depression. As a second hypothesis in the study, the researcher is studying the impact of a significant lack of social support in triggering the onset of depression in such people. If Dora’s research successfully validates both hypotheses, which of the following conclusion may be drawn?

To make improvements in your fitness you need to overload your body. You need to stress or challenge the bodily system (aerobic/musculoskeletal) beyond what it is used to.

2) Specificity Principle

Your exercise program must be specifically related to your training goals.

4) Reversibility Principle

Not being as good as something as you used to.

The four principles of building fitness are: Progressive Overload, Specificity, Rest and Recovery, Individuality.

1. Progressive Overload: This principle states that in order to improve fitness, the body must be exposed to progressively increasing levels of stress or challenge. This can be achieved by gradually increasing the intensity, duration, or frequency of exercise over time.

2. Specificity: The principle of specificity emphasizes the need to train specific fitness components or skills to achieve desired adaptations.

3. Rest and Recovery: Adequate rest and recovery are essential for building fitness. During exercise, the body undergoes stress and micro-damage, and rest periods allow for repair and adaptation to occur.

4. Individuality: Recognizing individual differences is a key principle in building fitness. Each person has unique characteristics, goals, abilities, and limitations.

Fitness programs should be tailored to individual needs and preferences, taking into account factors such as age, fitness level, health status, and personal circumstances.
