+Skill
Ability to do a specific Task
+What are skills?
Sport Skills: Skills needed to perform vigorous activities such as sports.
Motor Skills: Skills that are needed to move but not necessarily for vigorous activities such as sports.
Motor Units: when nerves and muscles work together as they are signaled by the brain.
Performance Skills: Skills used in activities other than sports.
+Practice
We learn skills with PRACTICE and are able to function effectively.
The younger you are, the easier you may learn skills.
Basic skills and sport skills are learned in elementary and middle school.
+Parts of Skill-Related Physical Fitness
AGILITY
The ability to change body positions quickly and keep your body under control when it is moving.
Rope Games, Dancing, Wrestling, and defending in football and basketball.
+Parts of Skill-Related Physical Fitness
BALANCE
The ability to keep your body in a steady position while standing or moving.
Balance helps you to ride a surfboard, ride a bike, and do activities such as the balance beam in gymnastics.
+Parts of Skill-Related Physical Fitness COORDINATION
The ability of body parts to work together when you perform an activity. Hitting a ball requires the use of your eyes together with your hands and arms.
Jumping hurdles, kickboxing, and aerobic dance require your eyes, feet, and legs. Kicking and performing dance steps require coordination.
+Parts of Skill-Related Physical Fitness
POWER
The ability to combine strength with speed while moving. A shot putter combines strength with speed to perform with power.
A softball player who swings the bat quickly and with a lot of force demonstrates power.
+Parts of Skill-Related Physical Fitness
REACTION TIME
The ability to move quickly when you get a signal to start moving.
A swimmer or runner starting a race needs good reaction time.
+Parts of Skill-Related Physical Fitness
SPEED
The ability to get from one place to another in the shortest possible time.
You can have speed of your whole body, such as when you move your hands very quickly to steal a ball from another person in a basketball game.

First-Class Levers
Lever
Mental Practice
Paralysis by analysis
Practice
Routine
Second-Class levers
Third-Class levers
+What is practice?
Repeating an action over and over to improve skill.
+What is feedback?
Information that the instructor “feeds” or gives “back” to you after you perform a movement so you have a better idea of what you did.
Helps you to make appropriate changes so that you improve your performance.
+Biomechanical Principles: Levers
LEVER: Basic machine. A bar or stiff straight object that can be used to lift weight, increase force, or create speed.
+Biomechanical Principles: Levers
FIRST-CLASS LEVERS: Allow you to lift a heavy weight with a small amount of force. Ex: Whole body weight with the small leg muscles.
+Biomechanical Principles: Levers SECOND-CLASS LEVERS: Not common. Person doing a push-up.
Force required for the arms to lift the body is about half the total body weight.
+Biomechanical Principles: Levers THIRD-CLASS LEVERS: Most common. Pivot point at
the end. Muscles apply force to the lever near the pivot.
+Principle in Practice
Practice helps you use your body levers properly
Practice helps you improve speed
Practice helps you improve accuracy
+Paralysis by Analysis
Too much information given at one time
+Mental Practice
Imagining performing a skill properly.
+How often should you practice? Works best when you enjoy it and can focus on it.
Too long practices can get you tired or bored.
Find ways to make practice fun or use enjoyable practice drills.
Regular practices are necessary: Longer for athletes. Daily practice is best.
If you don’t practice, your body “forgets” the best way to perform skills.
