Bio & Society Fitness Tracker Unit Mod #1

sensors found on a smartwatch

accelerometer/gyroscope

barometer

EDA sensor

SpO2

PurePulse

temperature

accelerometers

detects changes in acceleration

measures: type/intensity of exercise

analyzes sleep patterns

SmartTrack

gyroscope

detects changes in motion around 3 axes (forward/lateral/vertical)

photoplethysmography

uses green light to measure heart rate & sleep patterns

more light absorbed = higher rate

PurePulse

barometer

measure changes in air pressure associated with altitude changes to determine vertical distance covered

(# of stairs climbed)

altitude increases -> air pressure decreases

altitude decreases -> air pressure increases

Sp02

red & infrared technology

detects blood oxygen saturation levels

EDA sensor - electrodermal activity sensor

measures changes in sweat levels on the skin (assesses stress)

cardio fitness level

numerical score based on age, weight & sex

heart rate zones

relationship of heart rate to fitness goals and energy usage

Fat Burn heart rate zone

50-69%

low -> medium intensity

body uses fat as fuel

Cardio heart rate zone

70-84%

medium -> high intensity

preferred heart strengthener

Peak heart rate zone

85%+

intense exercise

short duration, improves performance

hypertension

type 2 diabetes

heart disease

cancer

list the 4 diseases associated with increased body fat

obesity

cardiovascular/heart disease

type 2 diabetes

elevated blood cholesterol

certain forms of cancer

list the 5 diseases associated with sedentary lifestyles

age, activity level, sex & genetics

individual water needs based on

importance of water

transports nutrients & wastes

acts as medium for chemical reactions

negative effects of too little sleep

type 2 diabetes

mental health issues

heart disease

stroke

premature death

light sleep

50-60%

most responsive time in sleep

memory processing

body conducts metabolic processes

deep sleep

10-25%

brain mostly inactive

body focuses on maintenance

delta brain waves

REM sleep

Rapid Eye Movement

20-25%

muscles mostly inactive

most dreaming occurs here

heart rate data

overall cardiovascular health

sleep patterns

exercise intensity/heart rate zones

metabolism/metabolic activities

uses plethysmography technology

step count data

determines type, duration & frequency of movement

provides indication of health of a number of body systems

uses three axis accelerometer sensors

sleep pattern data

determines quality of nightly sleep & changes in sleep patterns

uses plethysmography & three axis accelerometers

calorie data

# of calories burned by analyzing physical data, heart rate, activity levels & basal metabolic rate

plays important role in understanding how much energy your body expends to perform vital functions and basic metabolism

water intake data

data entered directly by the user

plays important role in understanding metabolism

prevents dehydration due to physical activity

stress data

detects small changes in sweat levels on the skin & produces stress management score for personal assessment

uses EDA (electrodermal activity) sensor

basal metabolic rate

estimate of the amount of energy a body uses to perform vital functions daily

based on: age, body mass, genetics, physical activity & state of health

(avg: 1000-2000 calories daily)

sleep cycle

detectable variations that occur as an individual progresses through light, deep & REM stages of sleep

sleep score

indication of quality of person's nightly sleep & measures changes in sleep patterns

3 factors: duration, quality, restoration

calorie

the amount of energy required to raise the temperature of 1 gram of water by 1 degree C at sea level

(amount of energy found in an item of food)

BMI - body mass index

an estimate of body fat based on heigh and weight
