Q

What is the difference between physical activity and exercise?

A

Physical Activity
-A broad term used to describe all forms of large muscle movements including sports, dance, games, work, lifestyle activities, and exercise for fitness.

Exercise
-Any activity designed to develop or hone a skill or ability. Physical activity intended to improve strength, fitness and specific athletic skill or skills.

Q

What are some physical benefits of CV exercise? (6)

A
  • Reduce body fat.

  • Increase lung volume (and lung’s ability to take in O2).
  • Reduce demands on the heart (at rest and during exercise).
  • Lower BP.
  • Reduces risk factors for numerous disease.
17
Q

What are some mental benefits of CV exercise? (2)

A
  • Reduces anxiety.

- Improves mild-mod depression, self-esteem, and mood.

18
Q
