T13 - MOVEMENT CONTINUUM

3 categories of movement

• physical activity

• sedentary behaviour

• sleep

MET

• metabolic equivalent unit

• energy exuded at rest

stages of the movement continuum (L to R)

• sleep

• sedentary behhaviours

• light physical activity

• moderate physical activity

• vigorous physical activity

light activity

• 3 mets

  • standing, cooking, playing with pets, grooming

moderate

• 3-6 mets

  • gardening, horse grooming, patient care

vigorous

• >6

  • rugby, squash, tennis, running, moving furniture

why is it important to look at each movement type?

• recognition that major movements differentially impact physiological and physical health

• need to distinguish each to better understand their relationship

physical activity

• bodily movement produced by the skeletal muscles

• result in a metabolic rate over resting energy expenditure

physical inactivity

• insufficient physical activity level

• to meet physical activity recommendations

sedentary behaviour

• waking behavior characterized as energy expenditure

• <1.5 METS

• sitting, reclining or lying position

  • still expending energy

screen time

• time spent on screen-based behaviours

• while being sedentary or physically active

physical inactivity vs. sedentary behaviour (3)

1. measurement of sedentary behaviour

2. unique physiology of sedentary behaviour

3. unique nature of sedentary behaviour

sleep

• good quality sleep is essential for healthy functioning and development

silo vs. integrated guidelines

• assuming movement is its own silo is misleading

• implies they are unrelated to each other
