lab final review

bmi

weight (kilometers) / height (meters)² *actually square it*

can distinguish % body fat

Body Fat %

(1.46 x BMI) + (.14 x age) – (11.61 x sex) – 10.02

stadiometer

measure of height usually in cm, up against the wall

positioned with feet together and turned out or shoulder width apart

deep breath and stand up straight, lower headrest so its on the head

skin calipers

can determine body fat %, pinch skin then read after 3 secs of it resting/sitting

Physical activity

“any body movement produced by skeletal muscles that result in energy expenditure”

dimensions of physical activity

mode: type of exercise

intensity: how hard someone is working (rate of energy expenditure )

frequency: how often

duration: how long

mode in context

structured --------------- incidental

exercise, leisure, transportation, household, occupational

aerobic physical activity

require karge muscle groups and perform long enough to maintain or enhance cardio by using o2 support

muscular strengthening

activities targeting large muscle roups & improve muscular strength, endurance & power

strength: how much resistance can be overcome

endurance: how long you can do the activity

power: how quick you can do something

self reported survey / surveys

examples:

GPAQ asks about work household, and recreational

physical activity diary: logging physical activity

helpful but can be performative and too intricate, can forget

global questionnaires, quantitative questionnaires, short recalls

recall bias, cost effecting, details more generalizabile

pedometer

measure steps

best to wear them around your hip, center of gravity and tracks arm swing, foot swing movements

SOFIT

assessing PE classes by providing data on student activity levels, lesson context, and educator behavior

SOFIT activity levels

lying, sitting, standing, walking, vigorous

SOFIT lesson context

general context/management, knowledge, fitness, skill practice, game play, free play

bone strengthening

activity creating impact and muscle loading forces on bone

i.e hopping, jumping, skipping, walking

balance training

activity challenging postural control

i.e yoga, skateboarding, heel toe walking

flexibility

movements that improve range of motion around septic joints

i.e yoga, pilates, tai chi, static stretching

intensity

rate of energy expenditure

REE: resting energy expenditure

PAEE: any energy needed to do any activity

absolute intensity

intensity of activity is based on a standard energy output for the activity, METS

relative intensity

intensity of activity us relative to individuals fitness *vo max*

volume

time spent in each intensity classification over a period of time

i.e spin class

objective PA measure

quantify PA by biological signals like motion, ❤ rate, steps, self report

rosenthak effects

researcher bias where testers expect certain participants to perform better than others

hawthorne effect

participant bias where performance is changed when attention is paid

PA guidelines

adults: 150-300 moderate exercise min or 75-150 min of m/v exercise combined

older adults: multicomponent PA like muscle strength, aerobic, bone, balance activities

kids: 60 min of moderate aerobic PA, muscle & bone 3x week

preschoolers: 3 hrs of PA of any intensity, some bone activity incoporation

dimensions of health related factors

cardio, flexibility, body composition muscular

Physical fitness

activity: behavior

fitness: outcome
