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
