Active by Default:
Getting Communities Moving 10 Minutes at a Time
Toni (Antronette K) Yancey, MD, MPH Professor, Department of Health Services
Co-Director, UCLA KP Center for Health Equity
The Problem
Extremely Low US Physical
Activity Levels*
Mean moderate to vigorous intensity PA
levels: US adults = 6-10 min/day
PA Levels meeting federal recommendations:
<5% adults
<10% teens
<50% children
*when objectively measured—NHANES (Troiano et al., 2008)
Leisure Time Physical Activity Levels:
Little Change in >2 Decades
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
A potential solution
“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
Why worksites? The practical reasons… • Proportion of time spent at work is high & expanding
– Large proportion of daily caloric intake consumed during work hours
– Opportunities for physical activity outside of work hours may be limited
• Humans evolutionarily programmed for sedentariness & most won’t exercise on their own even if given instruction, encouragement and time, e.g., data entry workers reported stretching during only 25% of conventional breaks and 39% of supplementary breaks (Galinsky et al., 2007)
• Especially true for ethnic minority/low income populations who may work longer hours or multiple jobs, have longer commutes, and be single parents
Cross-sectional Workplace Studies
Employee Health Care Cost Savings
from Physical Activity
Among 23,490 employees at large corporation:
• Moderately active and very active employees had $250 less paid health care costs annually than sedentary employees across all weight statuses
• Savings were $450 for moderately and very active obese employees compared with their sedentary obese counterparts
Why worksites?
On the philosophical side…
• Changes made at work may spill over to home & school
• Growing realization of need for interventions to change the
physical & socio-cultural environment—work is important
context for such influence
• Recognition of cultural assets available to build upon, e.g.,
centrality of dance and music in ethnic minority populations
• Physical activity interventions focused solely on ―leisure-
time‖ behaviors less successful among lower income
individuals and people of color, especially women, those
with highest rates of chronic disease &obesity
• Need more interventions that ―push‖ vs. ―pull‖ someone to
choose active alternatives (i.e. make the active choice the
default choice that must be opted out of vs. opted in to)
Benefits of activity breaks • A simple 10% decrease in inactivity could decrease
healthcare spending by $150M/year
• Introducing 10-minute activity bouts in the workplace can:
Waist line, blood pressure, weight, and percent body fat
Appetite (relative appetite suppressant)
Urge to smoke
Stress and anxiety
Harmful effects of prolonged sitting
Speed and accuracy of data-entry
Engagement of inactive individuals
Mood, self-efficacy; self-esteem
Fruit and vegetable intake, water consumption
Overall (total) physical activity (due to spill-over to non-work settings)
Supportive work environment
Energy levels
Cognitive processing, especially executive function component (judgment, processing efficiency)
Bone density 11 11 11
Creating an Active School Day: Making activity the default option
Improving the quality of physical education (PE) and ensuring adherence to mandates for PE duration (200 min/10 d elementary/400 min/10 d secondary)
Integrating 10-minute Instant Recess break at scheduled time(s) of the day
Improving equipment & supervision to increase PA during recess
Establishing auto-free zones, e.g., bus drop-off point so that students & staff must walk 5-10 min.
Redesigning classrooms to substitute stability balls for chairs, rotations among small group activity stations
What Is Instant Recess®?
• Incorporation of 10-minute activity breaks into daily routine, e.g., on paid time or during non-PE classes
• Simple and easily replicable, low-impact, moderate intensity movements set to music and scientifically designed to produce a manageable level of exertion, positive and reinforcing affective responses and fitness improvements, and minimal injury risk for sedentary or overweight workers
• Structured to maximize accessibility & effectiveness while minimizing wasted time
• Implemented in over 1000 workplaces and thousands of schools since 1999, materials purchased in 45 states and DC, as well as 10 foreign countries
• Evaluated in foundation- & federally-funded studies
Short bouts easier for sedentary individuals, minimizing perspiration & hair/make-up disturbance
Variable intensity, low-impact physical activity accommodates higher proportion overweight, unfit and/or disabled individuals
Social support & desire for conformity drives participation
Activity breaks may be framed as fun, play, stress release, entitlement to move vs. exercise=work, drudgery, obligation to most people
Needed to counter negative activity framing typical in food policy debate
Integrating 10-Minute Instant Recess® Breaks into Organizational Routine
Activity Breaks Work! The rapidly growing evidence base
• Documented individual and organizational receptivity to integrating activity into routine ―conduct of business‖
• Contribute to daily accumulation of activity
• Motivational “teachable moment” helping inactive people link sedentariness to health status
• As little as 10 min./day improves BP, weight, waist circumference, mood, attention span, cumulative trauma, absenteeism, employee retention, bone mineral density, academic performance, discipline
• “Spill-over” to increases in active leisure
• Favorable return on investment — LL Bean mfg. plant gets 30 min. productivity for 15-min. investment (three 5-min. breaks per shift)
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

Replacements, Ltd. Greensboro, NC
• Instituted 10-minute group stretch breaks on the clock
every morning & afternoon 5 yrs ago in 550-employee
distribution center
• Occupational RN identified two departments with large
numbers of musculoskeletal complaints. Provided
instruction sheet to Dept #1 for individual use at their
desks; in Dept#2, turned on music and employees did the
stretches as a group ―on the clock‖ scheduled into the
daily routine.
• Dept #2 saw greater impact on musculoskeletal
complaints due to higher participation rates
• Decreases in workers’ comp claims led to decrease in
premiums
Westinghouse Plant College Station, Texas
• Study participants were employees who assembled computer boards
• Performed set of 23 flexibility and strength exercises designed to prevent lower-back & carpal tunnel injury
• 10 minutes each day on company time under supervision.
• Daily participation rates 97-100%
• Significant improvements observed in wrist flexion, wrist extension, lower-back flexibility, fatigue, and mood, compared with a control group that did not participate in these exercises
Danish Public Administration
Authority
• 616 office workers from 9 sites in dif. geographic areas
• 3-group design, all allotted 1 hr/wk during paid time:
A Three 20-min. neck & shoulder resistance training exercises
B Varied physical activity (PA)--organized walks, 8-min. aerobic & resistance exercise CD, steppers at copiers, hallway punching bags
C Attention controls—group discussion of worksite wellness—no PA!
• Both PA conditions worked compared with controls:
✪Statistically significant systolic BP (-6 mm Hg), body fat (-2.2%), shoulder & back pain
✪Statistically significant muscle strength, VO2max (aerobic capacity)
University of Kansas PAAC
