Every trauma, illness or long-term condition causes some decrease in a patient's overall level of ___.
What is the name given to an age-related loss of muscle mass and function?
What is sarcopenia?
Age-related loss of muscle mass and function
i.e your muscles get smaller and they're not as strong or fast-acting
The criteria for sarcopenia are
1. reduced muscle mass
2. reduced muscle strength
3. reduced physical performance
What is a test which can be used to measure each?
1. Any imaging - MRI, CT, DEXA
2. Hand grip dynamometry
3. Observe gait or sit-to-stand test
At what age does sarcopenia start?
At what age does sarcopenia accelerate?
At what age does sarcopenia
a) 30 years
b) 60 years
As you age, muscle mass decreases and ___ mass increases.
fat mass increases
What endocrine condition are older people more susceptible to?
Increased fat deposition causes insulin resistance (body needs to make more insulin to transport glucose into adipose tissue, sugar everywhere, beta cells, I can't remember endocrine come back to this)
Why is immobility described as a vicious cycle?
Immobile people develop muscle atrophy
Atrophied muscles hinder physical activity
So patients exercise less
Lack of exercise causes muscle atrophy
People with sarcopenia have weaker muscles, making them more prone to falls.
What nutrients, when deficient, increase the likelihood of fracture following a fall?
a) activity related
b) diet related
c) disease related causes of sarcopenia?
a) Muscle disuse
b) Starvation, malabsorption
c) Cachexia (e.g cancer cells using loads of energy, causing weight loss)
How is the rate of sarcopenia reduced?
resistance training and aerobic training
What is the recommended amount of exercise for adults?
150 mins of moderate exercise per week
or 30 mins 5x/week
What nutritional supplements are proven to reduce the rate of sarcopenia?
Which class of antihypertensive drug is thought to reduce the rate of sarcopenia?
