Chapter 9 - Therapeutic Exercise

Question 1

What is the order of recruitment for motor units?

Answer 1

1. Slow-twitch
2. Fast-twitch (IIa)
3. Fast-twitch (IIb)

Question 2

Muscle hypertrophy is observed after ____ weeks of training

Answer 2

6 – 8 weeks

Question 3

What is the effect of the Valsalva maneuver?

Answer 3

increases intrathoracic pressure, slows heart rate (HR), decreases the return of blood to the heart and increases venous pressure and cardiac work

Question 4

Why does muscle soreness develop?

Answer 4

decreased blood flow and reduced oxygen (ischemia) creates a temporary build-up of lactic acid and potassium

A cool-down period of low-intensity exercise can facilitate the return of oxygen to the muscle and reduce soreness

Question 5

Contraindications of resistance exercise

Answer 5

• inflammation

- pain

Question 6

How long should isometric exercises be held?

Answer 6

at least 6 seconds

Question 7

Progressive resistance exercise

Answer 7

uses the repetition maximum (RM), or the greatest amount of weight a muscle can move through the ROM a specific number of times. Three sets of 10 repetitions are completed with brief rests between sets. Progression of exercise begins with 10 reps at 50% 1 RM, followed by 10 reps at 75% 1 RM, and finally 10 reps at 100% 1 RM.

Question 8

What type of exercise should be used early in a rehab program?

Answer 8

high repetition, low-load exercises

Question 9

FITT equation

Answer 9

• Frequency
• Intensity
• Type
• Time

Question 10

How should obese individuals exercise?

Answer 10

• obese individuals should exercise at longer durations and lower intensities

Question 11

How do you calculate the minute ventilation

Answer 11

VE = respiratory rate x tidal volume

Question 12

How does balance training differ in an individual with ataxia?

Answer 12

the patient with ataxia requires the opposite progression: from dynamic stability activities to stabilizing activities: weight shifting through decrements (decreasing) ROM progressing to stability (steady holding)

Question 13

What are the contraindications of aquatic therapy?

Answer 13

• bowel or bladder incontinence
• severe kidney disease
• severe epilepsy
• severe cardiac or respiratory dysfunction
• severe peripheral vascular disease
• large open wounds, skin infections, colostomy
• bleeding or hemorrhage
• water and airborne infections
