Q

Poly vs Trivex

Study These Flashcards
A

Poly - standards, sports goggles, children

Trivex - superior impact resistance, optical clarity, and scratch resistance

24
Q

Benefits of Vermilion tinted lenses

Study These Flashcards
A
  1. Enhance contrast
  2. Excellent clarity in low light
  3. Enhance visibility against blue/green
25
Benefits of Brown/Grey/Green tinted lenses
- Reduce glare - Effective in bright light
26
Benefits of Yellow/Gold/Amber tinted lenses
- Provides strong depth perception - Efficient under hazy lighting
27
When designing a Sports Vision Program, what are our focuses? (Pyramid)
1. Monocularly sensory processing: VA, contrast sensitivity 2. Binocular sensory processing: stereo, depth perception 3. Neural processing: visual decision making 4. Visual integration/mechanics 5. On field goals
28
In Sports Vision, what system is used for a baseline evaluation?
SENAPTEC Sensory Station
29
Dynamic Visual Acuity
Either object is in motion and/or athlete is in motion
30
Difficulties with Dynamic VA can negatively impact:
1. Depth perception 2. Timing 3. Object detail variation 4. Perception span
31
Anticipation Timing
Amount of time it takes to determine where and when an object and an athletic movement will coincide
32
Peripheral Awareness
Ability to pay attention to what is in front (central vision) while being aware of that which is to the side (peripheral)
33
Deficits in Peripheral Awareness can cause an athlete to…
1. Lose objects 2. Be easily distracted by objects in periphery
34
Peripheral Field of Vision
Full extent of vision extending to 180 degrees, while focusing on a central fixed target
35
What is trained by SENAPTEC Strobe?
Visual processing/anticipation skills Trains connection between body, brain, and eyes
36
Perception Span
How quickly athlete can acquire visual information
37
Parts of brain associated with perception span
Parietal lobe Frontal lobe Hippocampus
38
Describe procedure for Football Drills w/ Strokes + How to make more difficult
1. Trainer and athlete 10 yards away 2. Trainer throws football to athlete until catches 5/5 throws 3. Decrease flicker rate More difficult: 1. Continue to decrease rate (increase level) 2. Vary trajectory and speed of throw 3. Decrease separation 4. Vary location of throw 5. Bosu ball or other balance system or on one foot 6. Change to monocular strobe
39
Visual Concentration
Ability to focus attention on given task at hand while filtering distractions
40
Deficit in visual concentration can cause
1. Objects to be visually lost 2. Decrease in accuracy and efficiency to react to stimulus
41
Go/No Go
Activity or inhibition based on sensory demand (visual or auditory)
42
Go/No Go: Go activated by: Inhibited by:
Activation: Pre-frontal cortex Inhibition: Dorsolateral and orbits frontal cortices
43
Depth Perception
Ability to interpret combined images from both eyes to judge distance, speeds, and spatial relationships
44
What part of the brain is important for **motion perception**?
Middle temporal visual area (V5)
45
Eye Movements: Pursuits + training methods
Following a moving target 1. Dynavision 2. Rotary pursuit 3. Marsden ball 4. Senaptec Sensory Station 5. Flashlight tag
46
Eye Movements: Saccades/Jumps + training methods
Ocular motility 1. H, V, and rotational saccades 2. Senaptec Sensory Station
47
Eye Movements: Z-axis Tracking + training methods
Follow moving object coming at you or away from you 1. Brock string 2. Ball toss
48
Multiple Object Tracking
1. Identify multiple objects in space 2. Identity objects as near, far, low, high, left, right 3. Maintain orientation of self in space 4. Determine priorities of objects in relation to task at hand
49
Focus Flexibility
Ability to change focus from one point in space to another rapidly w/o excess effort
50
Speed of Recognition + training methods
Ability to make quick visual decisions 1. Tachistoscope training 2. Scanning
51
Visualization
Positive mental imaging *the more details, the better*
52
Raw Foot Speed
How fast an athlete can run various distances
53
Eye-Foot Patterning
How proficiently an athlete can execute run patterns
54
Eye Foot REaction Time
How quickly athlete reacts visually to get their feet where they need to be
55
Eye to Hand Speed
Ability to react and respond with hands to a visual signal
56
Reaction Time
time required to perceive and respond to stimulation
57
Visual Reaction and Response Timing
Amount of time it takes for stimuli to travel from our visual system into out motor system to produce physical reaction
