Q
Why is it important to ask a client’s LIFESTYLE and what kind of information does it provide?
A
- Recreation: physical activities outside of the work environment “leisure time” - golf, ski, tennis, etc - gives general idea about other athleticism outside of gym / motivation towards enhancing performance - example: “better golf swing”

5
Q
JUST READ THIS OVER
What information (list 4) is important to collect in the client’s medical history?
Why is each important?
A
- Past Injuries: strong predictor of future musculskeletal injury during physical activity
- Past Surgeries: can cause pain and inflammation that can alter neural control to the affected muscles and joints if not rehabilitated properly
- Chronic Conditions: risk of chronic disease dramatically increase with lack of physical fitness
- Medications: meds may have an effect on the way the body (heart rate and blood pressure) as well as the way it may react to exercise
6
Q

22
Q
How do you determine a client’s estimated maximal heart rate or HRmax?

- Old method: Subtract client’s age by 220 example: 220 - 31 = 189
- New method: 208 - (70% of age)
23
Q

24
Q

or Rockport Walk Test
25
What are the percentage ranges for each zone for Target Heart Rate?
Zone 1: 65-75%
Zone 2: 76-85%
Zone 3: 86-95%
of maximal heart rate (HRmax) = target heart rate
26

What is the HR Reserve (HRR) method or the Karvonen Method?
27
What is the formula for the HR Reserve (HRR) method or the Karvonen Method?
THR = [desired intensity x (HRmax - HRrest)] + HRrest
example: THR = [(189 - 63) x 0.75] + 63 THR = [126 x 0.75] + 63 THR = [94.5] + 63 THR = 157.5 bpm
Multiply the percentage of intensity from the appropriate zone, times the difference between only your resting and maximum heart rate, then add back the resting heart rate.

What 3 underactive/long muscles would cause the knees to move outwards?
1. Adductors
2. Medial hamstring
3. Glut med/max (Can lead to TFL synergistically dominate for frontal plane control)
126
What 3 SHORT/OVERACTIVE muscles cause rounding of the lower back during overhead squat?
1. Hamstrings (short hams resist hip flex, so lumbar spine compensates)
2. Adductor magnus (attaches to ischial tuberosity and if short will resist hip flexion, so lumbar spine compensates)
3. Rectus abdominis/external obliques (cause excessive spinal flexion)
127
What 4 LONG/UNDERACTIVE muscles cause rounding of the lower back during overhead squat?
1. Glut Max
2. Hip flexors
3. Intrinsic core stabilizers (can't stabilize spine) just like in spinal extension
4. Lats
128
The human movement system can also be referred to as what?
which is comprised of what 3 parts?
The kinetic chain
1. Nervous System
2. Muscular System
3. Skeletal System
129
The KINETIC CHAIN can be defied as what?
1. The human movement system
2. How different segments of the body work together
130
If one link breaks down in the kinetic chain what happens?
It will affect how well the rest of the structure can do its job.
131
What 4 factors lead to neuromuscular disfunction and arthrokinematics, which causes a chain reaction affecting other muscles and joints around the body?
1. Poor posture
2. Repetitive movement/Pattern overload
3. Lack of movement
4. Injury
132
What are 2 main neuromuscular issues that can happen from patterns of movement dysfunction?
1. Altered Recrprocal Inhibition
2. Synergistic Dominance
133
What is ALTERED RECIPRICAL INHIBITION?
When a tight muscle causes decreased neural drive of its antagonist. (the opposing muscle will be lengthened and in an underactive state)
134
Explain how tight hamstrings during a squat can demonstrate RECIPRICAL INHIBITION and SYNERGISTIC DOMINANCE.
- TIGHT HAMS during SQUATS (which use glutes and quads but some hams because of hip extension)
- Causes REDUCED SIGNALS from brain TO GLUT MAX (which performs majority of heavy lifting)
- Causes SYNERGISTS like PIRAFORMIS to TAKE OVER
135
What is the neuromuscular phenomenon that occurs when inappropriate muscles take over the function of a weak or inhibited prime mover.
Synnergistic Dominance
