How do our moitivations for PA change from a life course perspective
Childhood
- Joy, sense of accomplishment
Young adulthood
- Appearance, weight loss, body optimisation
Adulthood
- Avoiding injury, health maintenance, function
Later life
- Bedy function, social connection
PA across lifespan is correlated with
Happiness and Life Sat
If PA is low in early adulthood
It does not easily become part of life later on (particularly among blue collar workers, women, and people with poor perceived health)
PA, pleasure and older adults
Endorphins
Part of endocrine system (involving pituitary gland, hypothalamus, CNS
What happens during PA and how does this influence HPA axis
During PA, increased HR, muscle micro-tears, oxygen demand all activate the hypothalamus, and thus the HPA axis
Switching on HPA axis triggers production of endorphins
Effects of endorphins
Vagus nerve
Involved in PSNS, mice swimming studies show that swimming at moderate pace can activate vagus nerve.
Vagus nerve communicate with adrenal glands to increase dopamine release
Effect of dopamine
Decrease inflammation (help us w stress)
Maintaining positive embodiment in PA relies upon
Ways in which Yoga serves as positive embodiment
Traditional Chinese medicine and purpose of PA
Main idea = there are different ways to practice movement to better find balance with qualities of the seasons we experience
