  5. Never ________
  6. Avoid __________ joints
  7. Allow ______ between RT sessions using same muscle groups

Keep in ming OA need more time to recover

A

How to perform RT in a safe way for OA?

  1. Warm up muscles for at least 10 minutes
  2. Start with low resistance and gradually add reps, intensity (load) and sets
  3. Conduct exercises through a full pain free ROM
  4. Discontinue or adapt any exercises that cause pain or decrease resistance
  5. Never hold your breath - can increase BP, exhale during exertion and inhale during release phase
  6. Avoid hyperextending joints
  7. Allow 48 hours between RT sessions using same muscle groups

Keep in ming OA need more time to recover

Q

What are 2 structural changes in the neuromuscular junction

A
  1. Flattening of the cell membrane containing the receptors which leads to an increase in the distance btwn receptors and decrease in the quality of transmission
  2. Myelin sheath infiltration, it can migrate to synaptic cleft and partly block acetylcholine which will decrease signal transmission which will decrease the speed and strength of the muscle contraction
24
Q

Is resistance training as effective as aerobic training to decrease bp and insulin resistance

A

No, aerobic training = 3-5 mmHg decrease

RT = 2-3 mmHg decrease

25
Q

What were the exercise parameters of the program
Duration?
Frequency?
Intensity?

A
Duration = 8 weeks
Frequency = 3 x per week
Intensity = 50-80% 1 RM
26
Q

What were the results

A

HR and VR groups increases in FFM, strength
No significant change occurred during DAT
Time effect for heart rate and perceived exertion. Greater decrease in normalized integrated electromyography during the carry test in the VR group

27
Q

in OA if the training goal is power
Load?
Reps?

A

40-60%

6-10 reps

28
Q

What is the main difference between seated and standing cable pulley machines

A

Standing = postural muscles much more involved and mimics ADL’s more

29
Q

Frail OA can tolerate loads up to?

A

80% 1RM

30
Q

What are the health related benefits of resistance training for bone mass

A

improves bone health and reduces the risk of osteoporosis

Q

The highest BP and HR will occur in the las few reps of a set, avoid?

A

Avoid sets to failure in OA especially in those with CV problems

Q

Lower back pain

A

increased strength and vertebral = maintain muscular balance = decrease in low back pain muscles

Why should this be a priority?

to increase _________(body comp, bone mass, glucose tolerance, blood lipids) and __________(walking endurance)

A

to increase health benefits (body comp, bone mass, glucose tolerance, blood lipids) and performance benefits (walking endurance)

36
Q

What is the overload principle in OA

A

The capacity of the muscle cells to exert force increases relative to the demands placed on the muscular system
