Therex Flashcards
What type of exercise is needed to train the highly adaptable fast-twitch 2a fibers?
high intensity exercises for shorter durations (>20 reps)
intensity for resistance training
60-70% of 1RM for novice exercisers
40-50% of 1RM for beginners/older adult beginners/sedentary people
<50% 1RM to improve muscle endurance
20-50% 1RM for older adults to improve power
type of resistance training for healthy adults
multijoint and major muscle groups
repetitions for resistance training for healthy adults
8-12 for strength and power
10-15 for strength in middle-older age
15-25 for endurance
(2-4 sets, 2 or less good for endurance)
frequency for resistance training
2-3 days per week
frequency for aerobic training
5 or more days per week of moderate or 3 or more days for vigorous
time for aerobic training
30-60 min of moderate or 20-60 of vigorous
< 20 min for sedentary people
Pascal’s law (aquatic therapy)
- pressure exerted on an immersed body part is = on all surfaces
- increased pressure counteracts effusion and edema, and enhances peripheral blood flow
physiologic considerations for water immersion
- decreases weight bearing
- increases venous return and stroke volume
- reduces inspiratory reserve volume and may reduce forced vital capacity
Uncontrolled seizures within the last year are considered a contraindication for
aquatic therapy
Aquatic therapy is contraindicated for patients who have a vital capacity of
1 L or less
