What element of muscle performance is important to consider when trying to improve a patient’s abilities?
Motor control
-the correct movement pattern is essential to an exercise.
Though not functional and more of a strength base, isometric exercises should be held for how long?
6 to 10 seconds.
Concerning force, velocity and the strength of contractions, describe why more force generation means a slower motion.
More force = more actin/myosin filaments recruited for motion. For that to happen, there is an increase in the time requirement for the coupling and decoupling of those elements.
How fast can hypertrophy happen in young adults? Older?
3-4 weeks.
6-8 weeks in older adults.
What types of activities require endurance?
Postural
Athletic
Work
- for impaired muscle performance, endurance training tends to have a better effect on patients than strength training
- less force on joint, less stress to soft tissue
What are two different types of power (intensity and time)
High intensity, low time (box jump)
Low intensity, high time (long eccentric lowering from stair)
How does one incorporate the idea of 1RM into training?
As a baseline measurement for intensity of an exercise and as a guideline for selecting a training load. May be derived from a 10RM.
What are the 1RM training zones for healthy adults?
Strength: 60-100%
Power: 30-60%*
Endurance: s important.
Detail exercise prescription for strength, endurance and power activities.
Strength: 1-3 sets, 8-12 reps
Endurance: 2-4 sets, 13-22 reps
Power: 1-3 sets, 3-6 reps
What are rest parameters for low and high load exercise intrasession? What about intersession?
Low = 1-2 minutes High = 3-4 minutes
Post-surg or postural, several times per day
-resistive = alternating days
What are some signs of form fatigue (e.g. when the patient must discontinue ex or modify position or compensate)?
Discomfort
Cramping
Temors
Unable to complete full ROM
You know what the overload principle, specificity and overtraining are. How long does it take before detraining starts?
Can occur within a week or two after cessation of resistance exer training.
How do you progress exercises?
When patient can perform 1-2 reps over desired, increase load 2-10%.
If the pt can’t meet the exer demand, how would you regress?
- Reduce weight
- Change position
- Increase resting time
- Reduce reps or sets
-Progress 1 variable per session.
If soreness exists but goes away with warmup you continue to progress. What if it doesn’t go away?
Decrease to prior level of progression. If still sore, consider resting.
