Q

What is sedentary behaviour?

A
  • behaviour with <= 1.5 METs (metabolic equivalents of task)
    while seated, reclined, lying
  • independently increases disease risk and mortality
    (even if ppl are physically activity guidelines, but sitting lots too)

Functional capacity

A

6 min walk test

8 foot up and go test
- muscular power
- sit to stand from chair, walk 8 feet afap, walk around cone, return, sit down

46
Q

Assessment tools for
Cardioresp fitness

A

VO2 max
- max vol of O2 consumed during
(aerobic power)

Step testing
- 12 inch step, metronome
- steps for 3min to timing and rests for 1 min –> check HR and compare

Rockport fitness walking test
- 1 mile or 1.6km as fast as possible
- then measure HR
- estimate VO2 max with equation

12 min (Cooper) walk/run test
- cover max distance
- estimate VO2 with equation

47
Q

Assessment tools for
Muscular fitness
