Managing the Active Adult Flashcards
how does the WHO define health aging?
process of developing and maintaining the functional ability that enables well-being in older age
who are senior athletes?
- former competitive athletes
- have often sustained injuries in athletic career
- may/may not still be competing
- lifelong athletes
- may/may not compete
- athletic activity is a lifestyle
- nonathletes who picked up sports later in life
- may/may not compete
- initiation of exercise may be due to health crisis
describe some trends that occur with aging and sports performance
- runners of mean age 78 and running 60 min/week → lower levels of disability and prolonged survival
- 5x STS → faster in senior athletes vs community dwelling counterparts
- fall rates → lower in senior athletes vs community dwelling counterparts
- strength trained master athletes showed greater leg press max strength compared to recreationally active, sedentary young adults
neuromuscular changes that occur with aging
- loss of skeletal muscle → Type II muscle fibers
- women with greater loss of strength and power (especially UEs) than men
- strength loss at 2-5x rate faster than muscle mass loss (especially LEs)
- altered neural control, increased fat and connective tissue accumulation, changes in contractile units → reduced force
skeletal changes with aging
- OA common manifestation of joint deterioration
- BMD loss depends on skeletal loading
- master cyclists and swimmers < BMD than age-matched controls
- older runners > BMD than swimmers
- to prevent bone loss → add resistance training
cardiorespiratory changes with aging
- VO2 max
- central factors
- CO
- decline in HRmax
- Ventilation
- Peripheral factors
- lower a-VO2 diff
- loss of muscle mass
what are common injuries in active older adults?
- not enough data to really tell us
- knee and foot injuries appear to be more common
- injuries may be due to over training → but not enough data
- osteoarthritis
risk factors for osteoarthritis in active older adults
- type of sport
- training load
- BMI
- previous injury
what may be effective in reducing pain and improving function in older adults with OA?
resistance and aerobic exercise
what are the foundational movements important in movement performace?
kicking, running, and squatting
motor performance is influenced by ________ and __________ factors
physiologic and psychologic factors
- organismic (person) constraints (cardiovascular changes)
- environmental constraints ( lighting conditions)
- task constraints (size of golf club, dimensions of tennis court, etc.)
list several examples of mechanical constraints the impact motor/movement performance
- running → 5-7% speed reduction per decade in 100m sprint
- decreased stride length, GRF, leg stiffness
- reduced muscle thickness, type II muscle fiber size
- golf → reduced max club head speed
- decreased rotational strength, power, flexibility, balance
- altered biomechanics → decreased hitting distance
- swimming
- reduced stroke frequency, stroke length, and propelling efficiency
- cardiovascular and neuromuscular changes contribute to decline
list 5 principles of sports specific training
- specificity
- progressive overload
- variation
- reversibility
- individuality
describe specificity
physiological adaptations to exercise are specific to the stressors imposed by the type of exercise performed
describe progressive overload
stressors associated with a type of exercise must be sufficient level to elicit homeostatic disturbances to promote physiologic adaptation and must be incrementally increased over time
describe variation
systematic altering of one or more program variable(s) over time to allow for the exercise stimulus to remain challenging while preventing fatigue and stagnation
describe reversibility
removal of the exercise stimulus and physical inactivity will result in performance decrements
describe individuality
individual response to a given exercise stimulus
what are the 6 aspects of FITT-VP?
- Frequency
- Intensity
- Time
- Type
- Volume
- Progression
what are the resistance exercise recommendations for Hypertrophy in Older Active Adults?
- Modality → free weights; machines
- Frequency → 2-3 days/week on nonconsecutive days
- Intensity → 60-80% 1 RM
- Training volume → 1-3 sets/exercise, 8-12 reps/set
- Contraction velocity → slow to moderate
- rest intervals → 1-3 min between sets
- additional comments
- multiple and single joint exercises
what are the resistance exercise recommendations for strength in older active adults?
- Modality → free weights; machines
- Frequency → 2-3 days/week on nonconsecutive days
- Intensity → 60-80% of 1RM
- Training volume → 1-3 sets/exercise; 8-12 reps/set
- Contraction velocity → slow to moderate
- Rest intervals → 1-3 min between sets
- additional comments:
- multiple and single joint exercises
