- bouts of sitting time & breaking up sitting time
ACUSIT study protocol
observed effects of sedentary behaviour in elderly people
effect of sedentary behaviour on cardiovascular function

- negatively effects CV function
- worse effect the higher prolonged sitting time is
Profile Of Mood Subscales (POMS)
assessment for mood
effect of sedentary behaviour on mood
- significant increase in fatigue
