PE Chapter 6 Unit 2
POLICE (Protect, Optimal Load, Ice, Compression, Elevate)
New formula instead of rice:
Physical skills
Referred to as motor skills because learning them requires you to use motor units in your body (nerves that cause muscles to contract; parts in the muscles that are directed by the brain)
Skill-related fitness
Refers to a group of basic abilities that help you perform well in sports and activities requiring certain physical skills
Microtrauma
An injury to your body that you don't feel, but with repeated movements the symptoms of damage will appear
No because overuse is the damage of tissue, while overload is good build-up of physical activity
Are overuse and overload the same? Explain why or why not
Avoid stretching injuries, avoid twisting joints or forcing them to move in weird ways, balance your muscle development on both joint sides so they develop properly
Biomechanical rules for preventing injury:
Osteoblast
Calcium and minerals going to where you broke/cracked a bone
Health-related fitness
Considered the most important because it helps you maintain good health and wellness and perform well in physical activities
Hyperflexion
Exercises that cause you to use your joints in ways that are not intended to be used; bend your joints too far and overstretch your ligaments
Heredity, age, maturation, training, and sex
Factors that affect skill-related fitness:
Agility (changing your direction quickly), balance (moving your body where you want it to be), coordination (using senses and reacting to them quickly), reaction time (how long it takes you to react when instructed to), and speed (how fast you move from point A to point B)
Five parts of skill-related fitness (with description):
start slow, listen to your body, be fit, use moderation, avoid risk, and dress properly
Guidelines for preventing injuries during physical activity:
physical skills
Having good skill-related fitness allows you to learn __________________ more easily
6-8 weeks, recurring, strengthen
Healing time for a bone is__________. Once you have a joint problem, it is _______________, while bones ________________ once broken
Maturation and age
Hormones affect physical growth and development; some develop/grow earlier than others, and teens who do tend to perform better on skill-related fitness tests
Hyperextension
Increasing the angle of the joint too much; causes joints to move in ways that are not intended and applies force inappropriately
Sprain
Injury to a ligament (in between two bones); most common is ankle
Strain
Injury to a muscle or tendon
Leadership
Involves motivating people in a group to work towards a common goal
Teamwork
Involves team members striving to achieve a common goal through cooperative effort
desire and motivation
Lack of inherited ability (heredity) can sometimes be made up for by...
Concussion
Your brain banging against the inside or your skull cage
perfect practice makes perfect
Practice doesn't make perfect...
Determine your needs through self-assessment, identify your strengths and weaknesses, choose specific activities that will benefit/improve what you want improved
Program planning in skill-related fitness:
rest (depends on injury), ice (helps reduce swelling), compression (helps reduce swelling), elevation (brings swelling out)
RICE formula for treating injuries:
Heredity
Relates to physical characteristics we inherit from our parents
Overuse injury
Results from the repetition of movements that place wear and tear on your body
cuts, scrapes, bruises, blisters, sprain, strain, bone breaks, concussions, joint dislocations
Some activity-related physical injuries:
Skills
The ability to perform a specific task that is acquired through knowledge and developed through practice
Practice (repeating a skill many times) and knowledge (need to have basic information of how to perform skills and practice)
Two most important factors that influence skill learning (with description):
Motivation
What is important in teamwork and leadership?
training
With the right kind of ________________ you can improve your skill-related fitness; takes time and motivation, and requires the principle of specificity
Flexion
bending a joint
Extension
straightening of a joint
