7 The Research What do we actually know?

8 How This All Started 1953 London Bus Study higher mortality in drivers than conductors. Health researchers have been making the correlations between increased risk of adverse health outcomes & sedentary living for 20+ years. Historically, however, this has focused on the implications for exercise, nutrition, etc. The research on Non-Exercise Activity Thermogenesis (NEAT) began to heat up in the early 2000 s. Concurrently, epidemiological studies that looked at population wide effects of sedentary life began to be published at an increasing rate. Correlations have been increasingly drawn in the media over the last 5-10 years.

9 It s all about the METs Metabolic equivalent (MET) measures the intensity of activity in terms of energy expenditure. MET Measures Per Activity: Laying Down / Reclining / Sleeping =.9 METs Quiet Sitting / TV Watching = 1 MET Quiet Standing = 1.2 METs Talking / Eating While Sitting = 1.5 METs Working at a Desk While Sitting = 1.5 METs Working at a Desk While Standing = <2.0 METs Walking 3.0 MPH = 3.0 METs Activity 1.5 METs or less is typically classed as SEDENTARY

10 It s all about the METs SUMMING IT UP Sitting at a workstation all day is a sedentary activity. Standing can barely be considered light activity. Sedentary activities are bad for you. Use caution with product benefit claims.

11 Can more standing help? Standing burns approximately 20% more calories than sitting. This works out to be approximately 10 more calories an hour! Standing boosts the production of the enzyme lipoprotein lipase (which turns bad cholesterol into good) and reduces glucose resistance. Standing has been shown to be helpful in addressing abdominal fat storage. Standing is an alternative to sitting which can be used to vary posture throughout the day. BUT

12 Prolonged Standing is BAD Stationary standing is correlated with extremely high incidence of low back pain, even in participants who had no prior history of low back discomfort. People working in a fixed standing posture are at a significantly greater risk of cardiovascular disease, blood clots, varicose veins, leg cramps, leg swelling, pregnancy complications and birth defects than those working in a fixed sitting posture.

13 The ROI of Standing Positive ROI for Sit/Stand workstations in facilities with high churn (moves) Briotix ROI calculator 21-42% increase in walking reference below Lack of longitudinal studies (Bibbs et al.,2014) and determining if effects are short term and can be translated into long term health benefits (Garrett et al.,2016)

15 What do we know about sit-stand desks? The research is uncertain (long term benefits?). The rate of adoption post implementation declines rapidly after 1 month. Self reported comfort measures and symptoms sometimes improve but there is a lack of high quality analysis and statistically significant findings. The studies that have shown positive results have specifically identified that the equipment must be provided along with specific training on use, a supportive management climate, and a participatory organizational culture which have been shown to improve movement rates without height adjustable equipment.

16 What about low cost solutions?

17 In summary People are not designed to sit all day People are not designed to stand all day Sit stand workstations haven t yet proven long term changes to movement behavior Standing simply substitutes another risky posture into the mix To achieve better health we need to MOVE MORE

18 So what s the answer? There are really two goals or outcomes we can aim at 1. How do we PREVENT further DECLINE in health & TREAT chronic conditions (e.g. return to population baseline)? 1. How do we IMPROVE the health and wellness of a sedentary population?

19 PREVENTION Simply stand up once every 15 minutes. The simple activity of standing up 30 to 35 times a day (which is akin to a squat) is enough to maintain your health and prevent a decline from sedentary life. (NASA, Vernikos)
