Secondary prevention: Early diagnosis & reduction of the severity or duration of existing disease & sequelae.
Tertiary prevention: Use of rehabilitation to reduce the degree or limit the progression of existing disability & improve multiple aspects of function in persons with chronic, irreversible disease.
What are the 4 risk factors of disablement and give example of each
Biological
age, sex, race, height, weight, congenital disorders, family history of disease.
Behavioral/Psychological/lifestyle
Sedentary lifestyle, use of drugs, poor nutrition, low level of motivation, inadequate coping skills, difficulty dealing with change, negative affect.
Physical environment characteristics
Architectural barriers in the home, community & work; ergonomic characteristics of the home, work or school environment.
Socioeconomic factors
- Low economic status, low level of education, inadequate access to healthcare, limited family or social support.
What are the strategies used for effective exercise and task-specific instructions?
- Select nondestructive environment
- Demonstrate & make patient to model your movement
- Guide patient through movement
- Use clear & concise verbal & written directions
- Complement written instructions for home program with illustration of exercises
- Have the patient demonstrate an exercise to you as you supervise & -provide feedback.
- Provide specific, action-related feedback rather than general, nondestructive feedback.
- Teach an entire exercise program in small increments to allow time for patient to practice & learn components of the programme over several visits.
Name and describe the three types of tasks of motor learning
- Discrete task: involves a movement with a recognizable beginning & end.
- Serial task: composed of a series of discrete movements that are combined in a particular sequence.
- Continuous task: involves a repetitive, uninterrupted movement that have no distinct beginning & ending.
What factors influence motor learning during exercise instruction & functional training?
Pre-practice consideration
Practice
Feedback (intrinsic feedback, augmented feedback, timing of feedback, frequency of feedback
What factors influence adherence to an exercise program?
Characteristic of the patient
Factors to health condition or impairment
Program related variables
What is resisted exercise?
Any form of exercise that forces the skeletal muscles (not the involuntary muscles of your heart, lungs, etc.) to contract.
An external resistance (such as heavy weights) is used to cause the contractions, and those contractions lead to increases in muscular mass, strength, endurance and tone
What are the benefits of resisted exercise?
Enhance muscle performance.
Increase strength of connective tissue.
Greater mineral density.
Decreased stress on joints during physical activity.
Reduced risk of soft tissue injury during activity.
Possible improvement in balance
Enhanced physical performance during daily living, occupational, recreational activities.
Positive changes in body composition: lean muscle mass & body fat↓
Enhanced feeling of physical well-being
What are the 3 components of strengthening?
Strength, power and endurance
Define 1RM
One-repetition maximum (one rep maximum or 1RM) in weight training is the maximum amount of force that can be generated in one maximal contraction.
One repetition maximum can be used for determining an individual’s maximum strength and is the method for determining the winner in events such as powerlifting and weightlifting competitions.
One repetition maximum can also be used as an upper limit, in order to determine the desired “load” for an exercise (as a percentage of the 1RM).
Describe the 4 levels of intensity with regards to exercise
Low strength 30% to 40% of 1RM for sedentary, untrained individuals
Mild strength 40 to 60% of 1RM
Moderate strength 60% to 70% of 1RM, healthy individuals
Very high strength 80% to 95% of 1RM for highly trained individuals
THR (target heart rate) formula
THR = MHR (max HR) x 60%
= (220 - age) x 0.6
Name and describe the 6 principles of training
- Overload
Increase in demand to force bodily adaptation.
To stimulate an improvement in the physical condition of the body, it must experience physical stresses greater than those it would normally encounter.
2.Training adaptation
Body’s response to physical stress.
When the body is subjected to appropriate overload, it will adapt to physical demands.
- Specificity
Changes occur to the parts that are stressed.
Type of training effects produced by the exercise are specific to that type of exercise.
Must be specific to the type of sport/activity. - Transfer of training
Carry over or cross over training
Training effect can occur from exercised limb to unexercised contra lateral limb - Individual differences
Training must meet individual needs.
Genetic, individual commitment, level of physical & mental maturity. - Reversibility
Stop strengthening the muscles will weakening the muscles.
Detraining
What are normal factors that affect strength?
Development Aging Gender Body types Training
What are abnormal factors affecting strength?
Injury
Disease
Disuse
Fatigue
What are the factors that contribute to the dosage of exercise prescribed at a patient?
Alignment of body segments Exercise intensity Volume of exercise Duration Frequency Recovery Mode of exercise (each one has an explanation, see lecture slides)
Name and describe the types of muscle contraction
- Isometric (static) contraction – muscle tension increases without change in muscle length.
- Dynamic concentric contraction - muscle shortens as it contracts.
- Dynamic eccentric contraction - muscle lengthens as it contracts
- Isokinetic contraction – dynamic contraction under controlled conditions
What are the 3 forms of resistance?
Manual resistance
Mechanical resistance
Body weight
What are the precautions or resisted training?
Valsalva manoeuvre Substitute motions Compensatory effort Overtraining and overwork Exercise induced muscle soreness Acute soreness Delayed onset muscle soreness – self study
What are the contraindication of resisted exercise?
During period of acute inflammatory conditions and diseases
Severe pain (joint and muscle)
Inflammation – 1st phase of healing
Severe cardiopulmonary disease
Name an describe the 3 types of stretching
- Static stretching - voluntary passive relaxation of muscle while it is elongated
- Dynamic stretching - A swinging, bouncing, or bobbing movement during the stretch as the final position in movement is not held
- Active stretching- involves active contraction of the agonist muscles to move a limb through a full ROM while the functional antagonist is being stretched
(Slow movements and Proprioceptive neuromuscular facilitation was also listed here but I don’t think it’s a type of stretching)
What are the components of a single exercise session?
Warm-up, Conditioning, Cool-down and Stretching
Each have a description, see lecture slides
What body systems are involved in response to exercise?
Musculoskeletal, Cardiovascular, Pulmonary, Nervous, GIT, Endocrine and Immune
What are the aerobic changes that occur in the musculoskeletal system with exercising?
- Increase in size and number of mitochondria
- Increase in capacity to generate ATP aerobically
- Increase the capacity in muscle to mobilise and oxidise fat
- Increase in myoglobin content
What are the acute adaptations that occur in the cardiovascular system with exercising?
- increase in heart rate, stroke volume, cardiac output and blood flow
- decrease in vascular resistance
What are the chronic adaptations that occur in the cardiovascular system with exercising?
- increase in plasma volume, red cell mass, total blood volume, maximal stroke volume, maximal cardiac output
- decrease in systolic and diastolic blood pressure
What are the long term aerobic changes to the cardiovascular system with exercising?
- heart size increases
- heart rate decreases with prolonged training
- Stroke volume increases at rest, which increases cardiac output
- Blood pressure increases acutely during endurance and strength training, but with prolonged training BP decreases
- oxygen uptake increases
What acute changes occur in the pulmonary system with exercising?
- rapid increase in ventilation, pulmonary blood flow and lung compliance
- airways dilate
- decrease resistance to air flow
- increased breathing volumes improves oxygen uptake
- increase in minute ventilation
- increase blood flow to exercising muscle
What changes occur in the nervous system with exercising?
- increased SNS activity
- increase endorphin release which improves mood
- increased NE release which decreases pain
- temporary increase in body temperature (contributes to decreased muscle tension, elevated mood, reduced anxiety and improved sleeping pattern)
- improve coordination and balance
- NE & E release stimulate pulmonary and CVS responses to increase oxygen to the muscles
- Growth hormone increases
- Testosterone and androgenic hormones increase
- cortisol increases to promote production of glucose
What changes occur in the immune system with exercising?
- increases in WBC
> this promotes healing and repair of injured tissue - overtraining has negative effects on the immune system
What changes occur to the GIT system with exercising?
- shunting of blood occurs
- increase in GIT mobility –> decreases constipation
- prolonged activity causes diarrhea, incontinence, stomach ache, vomiting, reflux and heartburn and sometimes rectal bleeding
