28
he PAR-Q primarily aimed at...
identifying individuals who require further medical evaluation before being allowed to exercise because they are at high risk for cardiovascular disease (CVD)
29
what happens when a client answers yes to one ore more questions on the PAR-Q?
the personal trainer should refer them to a physician for further medical screening before starting an exercise program
30
health history
a collection of information that is generally part of a medical physical or medical health history, which discuss relevant facts about the individual's history, including biographic, demographic, occupational, and general lifestyle (physical, mental, emotional, sociocultural, sexual, and sometimes spiritual) data
31
what are two important areas for the personal trainer to focus on?
the relevant answers provided about a client's occupation and general lifestyle traits
32
sample PAR-Q questions

2. chest pain during physical activity?
3. chest pain when not performing physical activity?
4. lose balance because of dizziness / lose consciousness?
5. bone or joint problem that could be made worse with physical activity?
6. any medications for blood pressure or for a heart condition?
7. any other reason why you should not engage in physical activity?
33
collecting information about a client's occupation helps personal trainers determine what?
- common movement patterns
| - typical energy expenditure levels during the course of an average day
34
how does collecting occupation information help a personal trainer?
it helps them to begin to recognize important clues about the client's musculoskeletal structure and function, potential health and physical limitations, and restrictions that could affect the safety and efficacy of an exercise program
35
sample occupation questions
1. current occupation?
2. extended periods of sitting?
3. extended periods of repetitive movements?
4. wear shoes with a heel?
5. cause you anxiety / mental stress?
36
effects of extended periods of sitting
- hips flexed for prolonged periods of time, which can lead to tight hip flexors (rectus femoris, tensor fascia latae, iliopsoas) and postural imbalances within the human movement system
- tendency for the shoulders and head to fatigue under the constant effect of gravity, which can lead to postural imbalances including rounding of the shoulders and a forward head
- indicative of low energy expenditure throughout the day and potentially poor cardiorespiratory condition
37
repetitive movement
a persistent motion that can cause musculoskeletal injury and dysfunction
38
effects of repetitive movements
they can create a pattern overload to muscles and joints, which may lead to tissue trauma and eventually kinetic chain dysfunction, especially in jobs that require a lot of overhead work or awkward positions such as construction or painting
39
working with the arms overhead for long periods of time may lead to...
- shoulder and neck soreness that may be the result of tightness in the latissimus dorsi and weakness in the rotator cuff
- this imbalance does not allow for proper shoulder motion stabilization during activity
40
effects of wearing shoes with a heel
- puts the ankle complex in a plantarflexed position for extended periods
- can lead to tightness in the gastrocnemius, soleus, and Achilles tendon, causing postural imbalance, such as decreased dorsiflexion and overpronation at the foot and ankle complex, resulting in flattening of the arch of the foot
41
effects of mental stress of anxiety
- elevated heart rate, blood pressure, and ventilation at rest and exercise
- can lead to abnormal (or dysfunctional) breathing patterns that may cause postural or musculoskeletal imbalances in the neck, shoulder, chest, and low-back muscles, which collectively can lead to postural distortion and human movement system dysfunction
42
what do lifestyle or personal questions pertain to?
a client's general lifestyle activities and habits
- smoking
- drinking
- exercise
- sleeping habits
- recreational activities
- hobbies
43
sample lifestyle questions
1. recreational activities (gold, tennis, skiing, etc.)?
| 2. hobbies (reading, gardening, working on cars, etc.)?
44

46
hobbies
refers to activities that a client might enjoy participating in on a regular basis, but are not necessarily athletic in nature
47
examples of hobbies
- gardening
- working on cars
- playing cards
- reading
- watching TV
- playing video games
48
true or false: hobbies do not need to be taken into account to create a training program
FALSE

49
why is obtaining a client's medical history important?
- it provides personal trainers with information about known or suspected chronic diseases, such as coronary heart disease, high blood pressure, or diabetes
- provides information about the client's past and current health status, as well as any past or recent injuries, surgeries, or other chronic health conditions
50
what can previous history of musculoskeletal injury predict?
future history of musculoskeletal injury during physical activity
51
effects of ankle sprains on the human movement system
- decrease the neural control to the gluteus medius and maximus
- lead to poor control of the lower extremities during many functional activities, which can eventually lead to injury
52
effects of knee injuries involving ligaments
- decrease in the neural control to muscles that stabilize the patella (kneecap) and lead to further injury
- knee injuries that are not the result of contact (noncontact injuries) are often the result of ankle or hip dysfunctions, such as the result of an ankle sprain
- the knee is caught between the ankle and the hip: if the ankle or hip joint begins to function improperly, this results in altered movement and force distribution of the knee
- with time, this can lead to further injury
53
sample medical history questions
1. pain or injuries?
2. surgeries?
3. chronic diseases?
4. medications?
54
effects of low-back injuries
- decreased neural control to stabilizing muscles of the core, resulting in poor stabilization of the spine
- this can further lead to dysfunction in the upper and lower extremities
55
effects of shoulder injuries
-altered neural control of the rotator cuff muscles, which can lead to instability of the shoulder joint during functional activities
56
other injuries that result from human movement system imbalances
- repetitive hamstring strains
- groin strains
- patellar tendonitis (jumper's knee)
- plantar fasciitis (pain in the heel and bottom of the foot)
- posterior tibialis tendonitis (shin splints)
- biceps tendonitis (shoulder pain)
- headaches
57
effects of surgical procedures
- create trauma for the body
- may have similar effects on the functioning of the human movement system and safety and efficacy of exercise as those of injuries
58
common surgical procedures
- foot and ankle surgery

103
straight percentage method (peak maximal heart rate)
- a client's estimated maximal heart rate is found by subtracting their age from the number 220
- once their HR max is determined, multiply the estimated HR max by the approximate intensity (65-95%) at which the client should work while performing cardiorespiratory exercise to calculate THR
104
hr reserve (hrr) method (karvonen method)
-a method of establishing training intensity on the basis of the difference between a client's predicted maximal heart rate and their resting heart rate

steps to recording blood pressure
1. instruct the client to assume a comfortable seated position and place the appropriate size cuff on their arm just above the elbow
2. rest the arm on a supported chair and place the stethoscope over the brachial artery, using a minimal amount of pressure
3. continue by rapidly inflating the cuff to 20-30 mm Hg above the point at which the pulse can no longer be felt at the wrist
4. release the pressure at a rate of about 2 mm Hg per second, listening for a pulse

2 common submaximal tests for assessing cardiorespiratory efficiency
- YMCA 3-minute step test
| - Rockport Walk Test
196
YMCA 3-minute Step Test
designed to estimate an individual's cardiorespiratory fitness level on the basis of a submaximal bout of stair climbing set at a pace for 3 minutes
197
steps of the YMCA 3-minute Step Test
1. perform a 3-minute step test by having the client perform 96 steps per minute on a 12 inch step for a total of 3 minutes
2. within 5 seconds of completing the exercise, the clients resting heart rate is measured for a period of 60 seconds and recorded as the recovery pulse
3. locate the recovery pulse on the table
4. determine the appropriate starting program
5. determine the clients maximal heart rate and then determine the heart rate ranges for each zone
198
Rockport Walk Test
- designed to estimate a cardiovascular starting point
| - the starting point is then modified based on ability level
199
Rockport Walk Test steps
1. record the clients weight, have them walk 1 mile as fast as they can on a treadmill, record the time, and immediately record heart rate after the 1 minute mark, then determine the oxygen consumption scorer
2. locate the VO2 score on the table
