Children and adolescents
Define children.
Boys and girls who have not yet developed secondary sex characteristics
Define Adolescense.
A period of time between childhood and adulthood, generally including girls 12 to 18 years of age and boys 14 to 18 years of age
What are some benefits of physical activity for youth?
- Enhance cardiovascular fitness
- Increase muscular strength
- Improve metabolic health
- Also learn skills, make friends, have fun, and feel good about accomplishments
What is the recommended amount of moderate to vigorous physical activity (MVPA) for children and adolescents per day?
At least an average of 60 minutes per day across the week
(420 mins a week)
What types of activities should be included in the recommended physical activity for youth?
Both health- and skill-related activities
What are the three components of health-related physical activity?
Endurance, strength, flexibility
What are the components of skill-related physical activity?
- Agility
- Balance
- Coordination
- Speed
- Power
- Reaction time
Besides physical education and recess, where else should youth have regular opportunities for physical activity?
Before and after school
In the United States, what percentage of youth participate in 60 minutes of MVPA per day?
Only 24%
Are a majority of youth getting the recommended ammount of MVPA?
No
When does a decline and disinterest in physical activity tend to emerge in youth?
Early in life
What are some areas of concern related to youth physical activity levels?
- Poor fundamental movement skills, low muscle strength
- Also, technological advances and social media have decreased the need to move, physical education is considered expendable in some communities, and the cost of participating in organized sports may be a barrier
What are the potential annual costs of maintaining current physical activity levels in terms of direct medical costs?
$1.1 trillion
What are the potential annual costs of maintaining current physical activity levels in terms of lost productivity?
$1.7 trillion
Why are fundamental movement skills important?
They are foundational for ongoing participation in more complex exercise and sport activities
What are the three categories of fundamental movement skills?
- Locomotor
- Object control
- Stability
Why is muscular strength important for youth?
Weaker youth are susceptible to the inevitable consequences of muscle disuse and dysfunction
