What type of strengthening exercise offers variable resistance?

What percentages of the 10 RM are used in both the Delorme and Oxford techniques?
100, 50, 75
What sequence does the Oxford technique use?
100 then 75 then 50 (regressive)
What are some advantages of isometric strengthening exercises?
They don't create shear forces, can be done early on in a rehab program without causing irritation to the injury, inexpensive
True or False: endurance training requires the use of light weights and several repetitions.
What principle needs to be followed in order to properly strengthen a muscle?
What kind of contractions are associated with isotonics?
Concentric and eccentric
Name a disadvantage of using isotonic with weights.
Strengthening occurs in the weakest part of the range of motion only.
What have manufactures done to overcome the disadvantage of performing isotonics with weights?
They have added a cam that deflects the pull of the resistance thus allowing for variable resistance throughout the ROM
True or False: according to Pascal's law, the amount of pressure exerted on a body in water increases as the depth of immersion increases.
Cameron page 247
Name the two factors that contribute to an increase in the work of breathing in patients who's whole body is immersed in water?
Shift of venous blood from the peripheral to central circulation and hydrostatic pressure on the chest wall.
Page 251
What are the benefits of buoyancy in the rehab of patients.
Buoyancy is used to decrease the weightbearing forces on joints. Neck-90% reduction in WB, Xiphoid-70%reduction and ASIS-50%
What are the physiological effects of hydrotherapy?
Cleansing, Musculoskeletal, Cardiovascular, Respiratory, Renal and Psychological
Cameron page 266
What are the MS effects associated with aquatic therapy?
Decreased WB forces, Strengthening, More fat loss than with other forms of exercise, slowed bone density loss
True or False: If the specfic gravity of an object is less than 1, then it will float in water.
Page 263
What property of water provides resistance to the motion of a body in water?
True or False: The amount of resistance offered by water increases in proportion to the speed of the body's motion.
Name the 5 contraindicaitions for FULL body immersion hydrotherapy.
Cardiac insufficiency, infectious conditions that can spread by water, bowel incontinence, severe epilepsy, and suicidal patients
What kind of whirlpool should be used with full body immersion?
Hubbard Tank
Page 268
What is the ratio of warm water immersion to cold water immersion when perfroming a contract bath?
3 or 4 minutes:1 minute
Page 270
What should the temperture of the water be when using a whirlpool to achieve soft tissue extensibility?
40-43 degrees C or 104-110 degrees F
Page 267
True or false: when performing a contrast bath on a patient, the patient should end the treatment in the warm water.
Page 270
What temperature range should an excerise pool be kept at?
26-36 degrees C or 79-97 degrees F
Page 270
True or false: the water temperature for an exercise pool should not be allowed to be below 20 degrees C.
False, 18.5 degrees C or 65 degrees C
Page 270
What method of measuring exercise intensity should be used with patients involved in a water exercise program?
Preceived exertion
Page 251
True or False: peforming an exercise in water increases the metabolic rate and energy expenditure by approximately a factor of 3 when compared to the same activity performed at the same speed in water as on dry land.
What are 6 adverse effects assoicated with hydrotherapy?
Drowing, Burns, fainting and bleeding, hyponatermia, infection, aggravation of edema and asthma excerbation
When cleaning a whirlpool after a patient who had an open wound, what should the PTA use first, detergent or disinfectant?
The detergent should be used first because most disinfectants are inactivated in the presence of blood or tissue debris.
True or False: The mode of exercise refers to the type of contraction the patient is performing.
6th Edition page 175
Name 3 variables that can alter the amount of resistance offered by theraband?
Color, the amount of tension and the angle that the theraband is to the moving part. To get maximum resistance the theraband resistance should be at a 90 degree angle.
Theraband offers what kind of resistance?
What is the sequence of muscle contractions that produce the most force to the least amount of force?
Eccentric, Isometric and Concentric
Define Hypertrophy
An increase in the size of an individual muscle fiber caused by an increase in myofibrillar volume.
Define Hyperplasia
An increase in the number of muscle fibers.
What is the volume of exercise if a patient does 1 set of 10 reps using 2, 4, and 6 pounds.
120 (2x10+4x10+6x10)
What is the relationship of load and reps when trying to increase endurance?
Low load and high reps
What is the relationship of load and reps when trying to increase strength?
High loads and low reps
What type of muscle fibers have a high resistance to fatigue?
Tonic, slow-twitch (type I)
What is the recommended rest time between sets when performing rigorous strengthening exercises?
3-4 minutes
Define Overload
If muscle performance is to improve, then they must be challenged to perform at a level greater than that to which it is accustomed
What kind of contraction works against gravity?
True or False: Patients should be instructed to exhale during exertion.
Box 6.11 page 194
List the contraindications for Resistive Exercises.
Pain, inflammation and Severe cardio-vascular disease
When performing isometric exercises, what increment (in degrees) do you need to progress the patient?
10 degrees
Name a closed kinetic exercise for the triceps.
A patient is performing shoulder flexion in supine with a weight. Describe the type of contractions that occur during the exercise.
0-90 degrees, concentric shoulder flexors, 90-180 degrees, eccentric to the shoulder extensors
Name 4 strategies that you can use to avoid a Valsalva maneuver?
1. Caution the patient about breath-holding
2. Ask the patient to count
3. Have the patient exhale with each resisted effort
4. Do not let high-risk patients perform high-intensity resistance exercises
Page 194
Differentiate overtraining from overwork.
Overtraining pertains to a decline in physical performance in healthy individuals participating in high-intensity, high-volume strength and endurance training programs.
Page 195
DOMS is associated with what types of muscle contractions?
True of False: with a concentric contraction, greater number of motor units must be recruited to control the same load compared to eccentric contraction.
True of False: training induced gains in muscle strength and mass are greater with maximum-effort concentric training than max-effort eccentric training.
False, eccentric
Box 6.8 pate 182 6th Edition
True of False: greater loads can be controlled with eccentric than concentric exercise.
