Concept explainers
To determine: The difference between movement and physical activity.
Introduction: A physical activity is an intentional movement that is done to achieve a particular goal. A physical activity includes not only playing sports, but also activities in the daily routine. For example: Cleaning a house, washing the clothes and dishes, shopping, and walking in a garden are also included in physical activities.
Explanation of Solution
The differences between movement and physical activity are as follows:
No. | Characteristics | Physical activity | Movement |
1. | Definition | The intentional and voluntary movement that is done to achieve a particular goal is called physical activity. | The change in position of one or more body parts or the entire body is known as a movement. |
2. | Features | Physical activity is always voluntary. | Movement can be voluntary or involuntary. |
3. | Example | Swimming in a pool, javelin throw, and running. | Movement of limbs, eyelids, and head |
To provide: An example of human movement that does not satisfy the technical definition of physical activity.
Introduction: Physical activities includes not only playing sports, but also activities in the daily routine. For example: Cleaning the house, washing clothes and dishes, shopping, and walking in garden are also included in physical activities.
Explanation of Solution
Most of the body movements do not meet the definition of physical activity in all the aspects. For example: Movement of eyelids when blinking is an involuntary movement. Swallowing food, expansion, and contraction of heart and lungs are involuntary movements that do not fit into the definition of physical activity.
