Week 4 - Problem Solving: How to Improve Strength Flashcards
the highest amount of effort exerted by the muscles of the body in order to overcome the most resistance in a SINGLE effort.
muscular strength
the ability of a muscle or group of muscles to sustain repeated contractions against a resistance for an extended period of time.
muscular endurance
ability of muscles to produce force in or at a given time.
muscle power
proportional to the speed at which you can apply the maximal force
muscle power
Name 4 assessments used for determining strength.
- MMT
- Functional Muscle Strength
- Dynamometer
- Pinch Gauge
When does muscular strength improve?
when muscle is stressed (so that an increase # of motor units are recruited).
Muscles must be stressed to the point of ____ in order to ____ and strengthen.
fatigue, hypertrophy
Name 5 exercised parameters that can be manipulated to improve strength.
- type of muscle contraction
- intensity or load
- duration of contraction
- rate or velocity of contraction
- frequency of exercise
Name 2 aspects of using occupations to increase strength.
- may be sufficient for strengthening
- may be more motivating
Name 2 aspects of using exercise to increase strength.
- can be specifically targeted.
- may be “occupation” for some
the systematic performance of planned physical movements, postures, or activities
therapeutic exercise
How does therapeutic exercise differ from traditional exercise programs?
they are designed by rehab professionals to achieve MEASURABLE outcomes.
Describe general guidelines for therapeutic exercises during the acute management phase.
- minimize joint effusion and interstitial edema
- reduce pain
- AROM as tolerated.
Describe general guidelines for therapeutic exercises during the sub acute management phase.
- minimize joint effusion and interstitial edema
- reduce pain
- PROM
- early controlled mobilization (if tendons repaired)
- don’t forget “non-involved” joints.
Describe general guidelines for therapeutic exercises during the rehabilitation management phase.
- restore ROM, muscular strength, endurance
- prepare for return to work, ADLs, leisure
muscles move through ROM
isotonic exercises
Name the 2 types of isotonic contractions.
- concentric
- eccentric
Name the 2 types of isotonic strengthening.
- Delorme technique of PROGRESSIVE resistive exercise
- Oxford technique of REGRESSIVE resistive exercise
Does active range alone strengthen a muscle?
No
Delorme technique
-start low and go up with weights - progressive
Oxford technique
-start high and go up with weights.
static muscle contraction with little/no change in muscle length
isometric
maximum contraction at a constant speed through full ROM usually done with Cybex machine; matched resistance
isokinetic
form of specificity training facilitating rapid strength and endurance, calls into play type II fast twitch muscle fibers.
plyometric
