Physical Activity + Health Promotion Flashcards
Why is PA for older pts important
They are the least physically active active of any age group
PA levels have been referenced as a modifiable risk factor a preventative measure as well as an intervention
Changes in mm with age
- Loss of mass, strength,power
- Sarcopenia- age related loss of mm function (major component in the development of frailty)
What are the categories(5) you assess sarcopenia in and what score is needed for more comprehensive eval
- strength
- assistence in walking
- rise from chair
- climb stairs
- falls
score of 4+ to assess further
Declines in isometric, concentric and eccentric strength will occur at which age, and be accelerated when
will decline from the age of 40+
Accelerated decline beyond the age of 60
What part of the body declines first
decline in lower body is more pronounced and occurs faster
When will u see a sig decline in flexibility
sig decline in hip, spine and ankle by the age of 70, more prominent in women
Gait differences in aging
preferred walking speed is slowing, stride length becomes shorter, steps more wide, increased gait variability
When do total number of mm fibres decline start
25
functional motor unit changes with aging
type 2 fast- reduces specificity (loss of power)
Fewer mm unites and they are serving larger areas
balance bw denervation and rein nervation is lost
@60 have 25-50% less fewer mm units than 20yold
Endocrine changes w age
- Increased insulin resistance
- decreased growth hormone
- reduction in sex hormones
- vit D Deficiency
- Increase in parathyroid hormone
What is frailty
most often defined as an aging related syndrome of physiological decline, characterized by marked vulnerability to adverse health outcomes
-dependent on your physiological state and how well you can respond to stressors (involves multiple body systems(
What % of those over 85 are frail
25-50% of imdv over 85 are frail
what supps are an option for those battling sarcopenia
L-Leuicine- could pot increase the effects of resistance training to prevent or manage sarcopenia
Hydroxymethylbutyrate- could pot increase the effects of resistance training to prevent or manage sarcopenia
Creatine
physical activity guideline for the older pt
150-300mins a week of mod intensity PA
75-150mins a week of big intensity activity
2 mins of mod intensity activity counts the same as how much vig
counts the same as 1 min of vig activity
