Sedentary Behavior Research Network
We suggest that journals formally define sedentary behaviour as any waking behaviour characterized by an energy expenditure ≤1.5 METs while in a sitting or reclining posture. In contrast, we suggest that authors use the term “inactive” to describe those who are performing insufficient amounts of MVPA (i.e., not meeting specified physical activity guidelines).
Sedentary Behaviour Research Network. 2012. Standardized use of the terms “sedentary” and “sedentary behaviours”. Appl Physiol Nutr Metab. 37: 540–542.
THIS is…..
What is
contributing to
sedentariness?
Recess!
Quality family time….
SITTING IS HAZARDOUS TO OUR HEALTH
Each 2-hr increment in sitting associated with 7% increase in Type 2 diabetes & 5% increase in obesity
Increasingly sedentary work over the past 50 yrs may account for the energy imbalance (+100 Calories) causing the obesity epidemic
Men who sit >23 hours a week of sedentary activity had a 64% greater risk of dying from heart disease than those who sit <11 hours a week, including many who routinely exercised
Work days are associated with nearly 1 hour more sitting than non-work days
Effects of Prolonged Sitting
Increase in sedentary work, entertainment &
transportation means 95% of Americans don’t get
enough physical activity
Sitting increases risk of death up to 40% & doubles
the risk of cardiovascular disease:
Shuts off electrical activity in leg muscles
Drops rates of calorie burning to 1/minute
Drops fat-burning enzymes by 90%
Drops good cholesterol & insulin effectiveness

Daily activity is exercise
“I work the third shift….I’m just always wiped out…”

A solution
Prevention vs. Treatment
Most experts agree that diet is most critical for weight loss (treating obesity), but physical activity (PA) is most critical for preventing weight gain (PAGAC, 2008)
Without increases in PA at a population level, impossible to decrease caloric intake sufficiently to achieve energy balance and get essential micronutrients (Hill et al., 2005)
White hunger drives eating, there is no inherent biological drive to be active in adulthood—therefore push strategies necessary to achieve population-wide PA increases (Yancey, 2009; 2010)
Population benefit estimates of risk factor
change: PA
3-minute bouts of PA 10 times per day lowers serum triglycerides to same extent as 1 continuous 30-minute bout of PA (Miyashita et al., 2006)
Sedentary behaviors (e.g., TV watching) as well as sub-optimal >moderate PA levels contributed to DM & obesity risk over 6 yrs in women (Hu et al., 2003)
Number of bouts as well as volume of PA correlated with youth overweight (Mark & Janssen, 2009)
“Bouts” more efficient at weight and waist control than “non-bout” PA in adults (Strath et al., 2008)
Manufacturing Facility
Has provided brief stretch breaks on company
time since 1982
Productivity measurements indicate 30 min.
returned productivity for every 15 min. invested
in exercise (5-min. breaks 3x/day)
Reduced work-related injuries from 14/yr to
essentially none within 1st 3 years
Stretch breaks are viewed as a safety measure
similar to wearing safety glasses
Have now increased to a few minutes every hour!
PAAC Cluster Randomized Controlled
Trial Outcomes Donnelly et al., Prev Med 2009
•Main effects on:
(1) accelerometry-monitored daily PA, in-school,
and outside school—both weekend, weekday
(2) improved academic achievement for reading,
math, spelling & compos. scores
•Disaggregated by exposure:
(1) 9 of 14 intervention schools averaged 75+ min.
active lessons/wk
(2) these schools showed signif. less increase in
BMI When teacher were active with students, student PA levels were significantly higher!
“Push” vs. “Pull”
Pull strategies: Majority of physical activity promotion efforts,
including traditional worksite prog. rely on individual motivation--largely unsuccessful at population level
--Improvements greater in individual inclined to be active
Examples: gym membership subsidies, stair prompt posters, lunchtime or after-work exercise classes
Push strategies: Efforts to make the active choice the default option—the path of least resistance, requiring individuals to “go out of their way” to make inactive choice
--Promise of broader engagement, including those at greater risk for obesity—including ethnic minority groups
Examples: walking meetings, exercise breaks during non-discretionary time at work, nearby parking restricted to disabled, scheduling meetings at a distance from workspace
What Is Instant Recess®?
What is Instant Recess®?
Instant Recess® is a 10-minute low-impact physical activity break that consists of: 7 – 8 aerobic-based callisthenic, dance, or sports related movements Upbeat, rhythmic music set at a moderate pace.
Tailored to represent cultural values and assets, popular sports,
and setting-specific elements e.g. California Endowment “Here and Now” IR
A “low-maintenance” physical activity strategy:
Low-cost (both money and time) No change of clothes necessary Can be modified to meet specific needs of an individual or organization. Can be used anytime, anywhere, by anybody
Basic Structure of an Instant Recess® Break
IR Breaks are designed to maximize energy expenditure Moves engage large muscle groups in the upper and lower
body.
IR Breaks are choreographed to be “do-able” for all ages, body types, and levels of coordination Each move is easy to learn, so that everyone can participate. Modifications available to tailor each move to your level, and
personal flair is highly encouraged!
IR breaks are designed to minimize risk of injury Your neck, back, and knees are protected to avoid injury
How Does Instant Recess® Work?
Creates opportunity on “paid time” Gives employees a brief mental and physical break
from the work day Provides a boost of energy during the “mid-
afternoon slump”
Also encourages changes to improve
the food environment at work With increased energy from taking daily recess
breaks, healthier snacks will taste better.
Employs multiple levels of influence: “Deliberate Practice” Social Support and Group Dynamics Motivational “teachable” moment
Studies
10-min. Instant Recess® during staff / training meetings longer than 1 hour
449 employees, mostly overweight, middle-aged women, ethnically diverse
90+% participation
Demonstrated feasibility of engagement regardless of weight or physical activity levels
Found group breaks add social conformity factor that positively influenced participation
“Teachable moment” - increased individual awareness of poor physical conditioning and health status

6 schools, n=647 students with baseline + follow-up data, 68 participating teachers/classrooms
Cluster RCT with early intervention-delayed intervention control groups--main outcome = school day pedometer readings (measured beginning & end of school day)
Final model: Linear regression of post-treatment steps on both intervention groups and baseline steps, clustered by school, and student ID (R2 = 0.2292, F = 78.41 (p < .001))
Results: Adjusting for intervention group, mean steps significantly increased with IR intervention (+1910.3 steps; p<.001)

Why Does Instant Recess® Work?
Minimal Cost For companies, minimal cost of time and money For employees, ability to use paid time to “recharge” The return on investment in terms of employee productivity is often
greater than the time invested
Made for Groups Group setting provides social support to engage in healthy behaviors Group setting also provides time to improve employee relationships and
boost morale
Reduces Barriers to Activity Initiated as a “default” activity rather than a “voluntary” option. Adjustable for all shapes, sizes, abilities, and fitness levels Minimizes perspiration, so prevents messing up hairstyles or work
clothes
