RESISTANCE EXERCISE Flashcards
To achieve adaptive changes in static muscle performance, an isometric contraction should be held for how many seconds?
6 seconds and no more than 10 seconds
-because muscle fatigue develops rapidly. This allows sufficient time for peak tension to develop and for metabolic changes to occur in the muscle.
This term refers to a system of isometric exercise in which resistance is applied, manually or mechanically, at multiple joint positions within the available ROM.
Multiple-angle isometrics
This form of isometric exercise is used to develop a submaximal but sustained level of cocontraction to improve postural stability or dynamic stability of a joint by means of midrange isometric contractions against resistance in antigravity positions and in weight-bearing postures if weight bearing is permissible.
Stabilization exercises, a type of isometric exercises
This type of isometric exercise involve low intensity isometric contractions performed against little to no resistance. They are used to decrease muscle pain and spasm and to promote relaxation and circulation after injury to soft tissues during the acutestage of healing.
Muscle-setting exercise
What is DOMS?
Delayed Onset Muscle Soreness
What is the difference between DeLorme and Oxford progressive resistance regimen exercise?
The DeLorme technique builds a warm-up period into the protocol, whereas the Oxford technique diminishes the resistance as the muscle fatigues.
the summation of the total number of repetitions and sets of a particular exercise during a single exercise session times the intensity of the exercise.
Volume
What are the symptoms of DOMS?
- Muscle soreness and aching
- Tenderness at myotendinous junction or muscle belly.
- Local edema and warmth
- Muscle stiffness
- Decreased ROM
- Decreased muscle strength
What type of activities causes the most severe DOMS symptoms?
High intensity eccentric exercises
What are the causes of DOMS?
- microscopic tearing of muscle
- high intensity eccentric exercise
DOMS develops how long after vigorous and unaccustomed resistance training?
Develops 12 to 24 hours and peaks at 48 to 72
-Signs and symptoms can last up to 10 to 14 days.
What are the 2 types of muscle soreness after exercise?
- Acute soreness (during or immediately after strenuous exercise caused by lack of adequate blood flow)
- Delayed Onset of Muscle Soreness
True or false. Dynamic resistance exercises are NOT contraindicated in the presence of acute inflammation of a joint.
False.
The use of dynamic resisted exercise can irritate the joint and cause more inflammation. Gentle setting (static) exercises against negligible resistance are appropriate.
True or false. Patients with severe coronary artery disease, carditis, or cardiac myopathy should not participate in vigorous physical activities including a resistance training program.
True.
Symptoms of over-training usually resolve in how long?
6-12 weeks, with rest and careful exercise regime
What are the adaptations of endurance training?
- increases in oxidative and metabolic capacities of muscle
- allow for better delivery and use of oxygen
What are the adaptations of strenght training?
- increase force produced by muscle
- increase muscle size
Muscle mass peaks in women between what ages?
16-20
