Biomechanics Final

Front 1

What is the difference between a qualitative and a quantitative biomechanical analysis?

Back 1

Qualitative - observation and subjective descriptions of mechanical movements
Quantitative - measurement and reporting numbers to describe movement

Front 2

What are the advantages of qualitative analysis?

Back 2

cheaper and very effective for novice to intermediate athletes

Front 3

When would quantitative analysis be useful?

Back 3

Finding very small errors that are naked to human senses in elite players

Front 4

What are the steps involved in making a qualitative analysis?

Back 4

1. Describe ideal
2. Observe performance
3. Eval - compare performance to ideal
4. Instruct - provide feedback to correct the errors found in performance

Front 5

What must one do to be able to describe the ideal technique?

Back 5

1. Gain fundamental knowledge through participating, reading books and journals, and know rules
2. Describe the goal of the skill in mechanical terms

Front 6

What can help describe complex skills?

Back 6

Dividing it into temporal divisions, e.g. tennis serve has cocking, foward swing, and followthrough.

Front 7

What are the factors in observing the performance?

Back 7

1. Whom you observe
2. Conditions
3. Vantage point
4. What to look for

Front 8

What is the most important question in evaluating the performer?

Back 8

Does the error dangerous to the performer? Is it an error that leads to injury?

Front 9

What questions should be considered in evaluating a performance?

Back 9

Does the error occur after another?
Does the error occur because of physical inadequacey?
Doest the error occur because of poor equipment?
Is the error easily fixed?
How great of an effect does the error have on the performance?

Front 10

What should the communication with the performer be like?

Back 10

Positive, simple, and specifice
only one error at a time
be patient with performance as it might decline while fixing the error

Front 11

What is the principle of specificity?

Back 11

It is key to replicate angular velocity and displacement, muscle actions, and external forces specific to the skills desired

Front 12

Define technical training

Back 12

Training geared towards performing the skill correctly as defined by the ideal technique from the qualitative biomechanical analysis

Front 13

How does an athlete effectively train technically?

Back 13

Mimic the movements of the skill or technique.
Drills need to be specific to skill

Front 14

What is often the best way of improving physical condition in training for a skill?

Back 14

Perform that skill

Front 15

What is the aim of physical training?

Back 15

To improve muscle strength, power, and endurace
To improve cardiovascular fitness
To improve body composition

Front 16

What are the steps in a qualitative anatomical analysis?

Back 16

1. Define temporal phases of skill
2. Describe joint motion during each phase
3. Identify muscle action types
4. Identify high accelerations
5. Identify extreme ROMs

Front 17

What does specificity require?

Back 17

Performance of the skill and drills that mimick the skill

Front 18

What force characteristics are related to injury prevalence?

Back 18

Magnitude
Area
Location
Rate
Direction
Frequency

Front 19

What other habits affect tissue ability to resist overuse injury?

Back 19

diet
genetics
sleep habits

Front 20

What are some intrinsic factors in injury?

Back 20

Body mass
Skeletal: density, alignment, and asymmetry
Muscular strength, endurance, and firing patters
Previous history of injury
Psychological: motivation and tolerance for pain

Front 21

What are some extrinsic factors in injury?

Back 21

Nature of task: frequency, speed, intensity, and duration
Level of participation
Equipment
Environment

Front 22

What factors should be considered in injury prevention?

Back 22

Force magnitude and frequency
Recovery time
Intrinsic and extrinsic factors
