Chapter 1-2 Quiz Flashcards
(28 cards)
Biomechanics
study of the effects of forces on living and non-living objects.
Do mechanic principles apply to athletes alone?
No. They are used to improve the efficiency of sport equipment and playing surfaces.
Technique
the pattern and sequence of movements that the athletes use to perform a sport skill, such as a forearm pass in volleyball, a hip throw in judo, or a somersaulting dive from the tower.
What is important in analyzing technique?
That you are able to analyze and correct faults in the novice’s performance and that you use good teaching progressions to lea the novice to a more refined performance.
What teaching methodology isn’t effective?
“What worked well in the past should work well now.”
Goals of Sports Mechanics
To better performance by technique improvement, equipment improvement, and training improvement.
Technique Improvement
Verbal feedback and observation.
Equipment Improvement
Shoes, apparel, implements.
Training Improvement
analysis of technique.
Injury Prevention
Alteration of technique, equipment (knee brace, ankle brace), and training specific regimen.
Good Technique
Is influenced by height, weight, and strength. This means that the technique based on the best use of analysis of human motion.
Failure of Traditional Methods
Making every workout the same in terms of physique, training, and maturity. All athletes differ in these areas, so one must individualize the workouts.
Mass
substance or matter. All massive objects are attracted to one another.
Gravitational Attraction
Changed according to how much mass, and how far apart objects are. Gravity pushes down more on massive objects.
Weight
represents the earth’s gravity pulling on an athlete’s body. Too much or too little can affect performance.
Altitude
Can affect weight due to distance from earth’s core. Higher altitude means less weight.
Inertia
Resistance to change. What moves slowly wants to continue to move slowly. Objects want to move in a straight line.
Newton I
I am going to keep doing what I am doing until another force acts upon me.
NewtonII
Acceleration is produced when a net force acts on a mass.
Speed
how fast an object is traveling at a specific moment in time.
Acceleration
Rate that speed changes.
Velocity
Speed and direction.
Density
mass contained in a certain space.
Center of Gravity
Equal mass above, below, left, and right. Muscle and bone are dense, but fat is not.
