Q

once VO2 max is determined, what is a common method to establish exercise training intensity?

A

have clients exercise at a percentage of their VO2 max

57
Q

why is measuring VO2 max often impractical?

A

the energy cost of physical activity as multiples of resting metabolic rate

65
Q

MET values are used to relate what with what?

A

to help improve cardiorespiratory fitness levels in apparently healthy sedentary clients

104
Q

who is stage 2 designed for?

A

clients with low-to-moderate cardiorespiratory fitness levels who are ready to begin training at higher intensity levels

105
Q

what is the focus of stage 2?

increasing the workload (speed, incline, level) in a way that will help the client alter heart rate in and out of zone 1 and zone 2

106
Q

stage 2 helps increase the cardiorespiratory capacity needed for the workout styles in the ___ level of the OPT model

A

strength

107
Q

stage 2 is the introduction to what?

A

interval training in which intensities are varied throughout the workout

108
Q

example of a stage 2 workout

A
  1. warm up in zone 1 for 5-10 min
  2. move into a 1 minute interval in zone 2. gradually increase the workload to raise the heart rate up to zone 2 within that minute. once the heart rate reaches zone 2 of maximal heart rate, maintain it for the rest of that minute. it might take 45s to reach that hear rate, which means the client will only be at the top end for 15s before reducing the workload and returning to zone 1
  3. after the 1 minute interval return to zone 1 for 3 minutes
  4. repeat this if the client has time and can recover back into the zone 1 range- the most important part of the interval is to recover back to zone 1 between the intervals
109

A

FALSE

-in stage 2, it is important to alternate days of the week with stage 1 training

112
Q

focus of stage 3

A

further increasing the workload (speed, incline, level) in a way that will help the client alter heart rate in and out of each zone

113
Q

stage 3 training increases the capacity of the energy systems needed at the ___ level of the OPT model

A

power

114
Q

example of a stage 3 workout

A
  1. warm up in zone 1 for 10 min
  2. increase the workload every 60s until reaching zone 3
  3. after pushing another minute in zone 3, decrease the workload
  4. drop workload down to level from before for one minute
  5. the faster the heart rate drops, the stronger the heart is getting
  6. if the client is not able to drop to the appropriate heart rate, client may be tired or about to overtrain- stay in zone 1 or 2 for rest of workout
  7. if hear rate drops to a normal rate, then overload the body again and go to the next zone, zone 3, for 1 min
  8. after this minute, go back to zone 1 for 5-10 min and repeat if desired
115
Q

how to minimize the risk of all overtraining

A

116
Q

how long should the intervals be in stage 3 at the start?

A

30-60 seconds

117
Q

what does circuit training allow for?

A
  • comparable fitness results without spending extended periods of time to achieve them
  • a very time-efficient manner in which to train a client
118
Q

kinetic chain deviations for clients who possess a rounded shoulder and/or forward head posture (upper crossed syndrome)

A
  • during use of stationary bikes, treadmills, and ellipticals, watch closely for rounding of shoulders forward and a protruding head
  • on steppers and treadmills, watch for the grasping of handles, which will cause elevated and protracted shoulders and a forward head (if possible, this equipment should be used without the assistance of the hands to increase the stabilization component, elevating the caloric expenditure and balance requirements)
  • in settings in which a TV is present, watch for excessive cervical extension or rotation of the head to view the TV
119
Q

kinetic chain deviations for clients who possess an anteriorly rotated pelvis and arched lower back (lower cross syndrome)

A
  • initial use of bikes and steppers may not be warranted, as the hips are placed in a constant state of flexion, adding to a shortened hip flexor complex. if they are used, emphasize corrective flexibility techniques for the hip flexors before and after use
  • treadmill speed should be kept at a controllable pace to avoid overstriding. the hips may not be able to properly extend and may cause the low back to overextend, placing increased stress on the low back. corrective flexibility for the hip flexors should be emphasized before and after use.
120
Q

kinetic chain deviations for clients whose feet turn out and/or knees move in (pronation distortion syndrome)

A
  • use of all cardio equipment that involves the lower extremities will require proper flexibility of the ankle joint. emphasize phone rolling and stretching for the calves, adductors, biceps femoris (short head), iliotibial (IT) band, and tensor fascia latae (TFL)
  • using the treadmill and steppers that require climbing (or aerobics classes) may initially be too extreme for constant repetition, especially if clients are allowed to hold on to the rails and speed up the pace. if these modalities are used, emphasize the flexibility exercises and keep the pace at a controllable speed
121
Q

circuit training

A

a series of resistance training exercises that an individual performs, one after the other, with minimal rest
