25
how would you define the "maximum limit of stability"?
the maximum distance a person can lean without moving the feet in any direction
26
what is the relationship between cognitive impairment and balance/fall risks?
it is an intrinsic risk factor; when attention, memory, and intelligence are declining it makes concentration on tasks difficult and affects OA ability to anticipate and adapt to changes in environment.
27
what are extrinsic risk factors for falls? What are some examples?
risk factors that are environmental or outside of the body: medication, environmental, aka tripping hazards, poor lighting, slippery surfaces, footwear, clothing etc.
28
what are intrinsic risk factors? What are some examples?
personal factors such as age, gender, race, changes to physiological systems: impairment to balance/gait, muscle weakness, impaired vision, hearing, cognition, symptoms from diseases
29
How is resting HR in the supine position affected by aging?
it is not affected, however age-related declines show up when moving from laying to seated position due to inability to rapidly increase HR. attributed to reduced responsiveness to sympathetic stimulation
30
what is the equation for predicting men's maximum HR?
predicted HRmax = 209.6-(.72-age)
31
what is the equation for predicting womens maximum HR?
predicted HRmax = 207.2-(.65-age)
32
why does the equation 220-age not work for older population?
it does not account for differences between men and women, and after the age of 40 it underestimates HRmax making HR based programming difficult.
33
what contributes to the reduced ability of OA to cope with hemodynamic perturbations that result from movement?
loss of vascular tone, higher blood pressure, reduced stroke volume leading to more difficulty adjusting to changes in HR when moving from recumbent to seated positions.
34
What happens to systolic blood pressure and diastolic blood pressure as a result of aging?
systolic blood pressure increases and diastolic BP decreases with age.
35
what age-related changes need to be taken into consideration when assessing performance?
vision, hearing, proprioception, medications, sleep, nutrition, and hydration
36
what muscle fibers atrophy at a greater rate due to aging?
type II muscle fibers, leads to loss of maximal muscle speed
37
what are subjective measurements of PA?
questionnaires
38
What are objective measurements of PA?
monitoring assessments that record data
39
What is sedentary behaviour?
any waking behaviour in a seated or reclined position that requires energy expenditure of less than or equal to 1.5METs
40
What are ADL's? examples?
Activities of daily living- activities that an OA must be able to perform to function independently; bathing or dressing or feeding oneself.
41
What are IADL's? ex.?
instrumental activities of daily living- important but not vital for independent living; shopping, managing finances
42
What is the most common self-reporting instrument?
Katz index of independence in ADL's; it is a 6 item questionnaire that measures ability to carry out simple self-care activities: bathing, dressing, use of bathroom, transferring, continence, feeding
43
What does the Lawton Instrumental ADLs questionnaire assess?
8 domains of IADLs in depth: includes activities such as running household: preparing meals, managing money, shopping for groceries, performing housework
44
What is considered moderate activity?
activity that increases energy expenditure greater than 3 METs
45
What is vigorous activity energy expenditure?
greater than or equal to 6 METs
46
What are some examples on how to reduce sedentary time?
make goals, self-monitoring, and stimulus control
47
What tests can measure endurance and power in older adults?
the timed up and go- TUG and the sit to stand
48
What does the TUG test assess?
individuals ability to rise from standard armchair, walk 10ft, turn around, walk back, and sit down.
49
What does the sit to stand test assess?
the maximum number of times a subject can stand up and sit down on a regular chair in a specified timeframe.
50
What are benefits of subjective measures?
accessible, variety of questionnaires to choose from, gives an idea of what kind of activity is or isn't being performed
51
What are drawbacks of subjective measures?
information might not be accurate, based on persons recall and honesty while answering questions
52
benefits of objective measures of PA?
reliable information, standardized results for comparison, accurate assessment of PA levels
53
Drawbacks of objective measures?
can be costly or inefficient if a lab setting and equipment is required.
54
what is the estimated global amount of physically inactive OA population ?
30-60%
55
what is the adapted social ecological model for physical activity?
a model that is based on four levels that influence PA behavioiur
56
What are the four factors on the adapted social ecological model?
individual, interpersonal, environmental, and policy factors
57
what is meant by intrapersonal factors?
factors directly involving individual person: health status, self-efficacy, enjoyment, expectations, ageism/attitudes, priorities, history of healthy habits.
58
what are the four primary sources of self-efficacy?
Mastery experiences, social modeling or vicarious experience, social persuasion, and interpretation of physiological and emotional responses
59
what are four types of reinforcement?
positive or negative, direct or vicarious
60
What are interpersonal factors?
relationships or actions between individuals that influence PA. Can be family members, peers, health care providers, or household pets
61
How does the social ecological model affect OA's level of PA?
barriers and facilitators of health behaviour interact across multiple levels so interventions should be considered. examples would be, state and local policies run programs for OA, ensure parks are accessible to get to, and offer transportation to particpate. this addresses many barriers that might prevent OA from joining.
62
what is the health risk appraisal tool, and what factors does it assess?
provides an individual with information about various aspects of their current health, risk factors, and fitness level. social factors, functional factors, somatic factors, psychological factors, environmental factors.
63
what are intrapersonal facilitators for PA in long-term care?
reduction of pain, prevention of falls, increased self-efficacy, physical abilities, and functional mobility, a sense of meaning and enjoyment, increased health benefits, and enhances QOL
64
what are intrapersonal barriers for PA in long-term care?
pain with PA, risk of falling, physical impairment or low level of function, fear of hurting the resident, fear of forcing residents to exercise if they don't want to, too much work for facilitator of exercise program.
65
What are interpersonal facilitators for PA in long-term care?
positive interaction with residents, including joy and gratefulness with class, decreased loneliness among residents and are burden among staff.
66
what are interpersonal barriers for PA in long-term care?
lack of appreciation, lack of support by staff, management, residents, and family members, lack of knowledge of the family members, staff, and management, lack of expectations for PA for some residents.
67
what is a masters athlete?
a former athlete who continues to participate in competitive sport later in life, or transfer to a new sport at an older age. over 35 is considered Masters athlete but cutoff varies per sport.
68
how does type of activity influence age-related function?
decreased the rate of decline in physical capabilities, individual activities vary per masters athlete but endurance training helps to maintain capacities as we age.
69
what training variables should be considered in masters athletes?
specificity is an important variable to address specific age-related declines in endurance and strength; progress overload is important for increases in adaptations; and proper recovery times as OA take longer to recover
70
besides physical benefits, what other benefits do masters athletes achieve?
psychological, cognitive, and social
71
how is PA related to psychological benefits?
improves mental health, emotional health, and self-concept status; helps to decrease depression into older age and increases enjoyment of participation and increase release of neurotransmitter serotonin.
72
How is PA related to cognitive benefits?
improves or maintains memory, processing speed, and verbal fluency; preserves specific brain regional volume related to visuospatial function, motor control, and working memory.
73
how does PA relate to social benefits?
higher social network from involvement in sport; enjoy companionship, friendship and social support that arises from participation
74
what are some physiological changes that result due to aging?
increased body fat, loss of muscle mass, loss of bone density, decreases in muscular strength and power, decreased aerobic capacity, increased risk of chronic disease.
75
what are the physiological changes from aging associated with that threaten independence and QOL?
diminished functional capacity, increased frailty, reduced sense of well-being
76
what are endocrine systems that change with aging?
decreased production of sex steroid hormones that result in menopause and andropause changes in adrenal function that lead to adrenopause, which is alterations to DHEA/S endocrine changes that lead to somatopause which affect GH/IGF-1
77
