The proof Examining the scientific background of DirectLife DirectLife Every movement counts
Many research studies have already confirmed a direct link between
increased levels of activity and improved health. Most people already know
that exercise is good for the body and soul. However, they also find it
difficult to turn good intentions into action. DirectLife is for those people
who really want to become more active, but want to do it in a way that fits
their daily routine. Of course, that’s easier said than done. How do you
motivate people to be more active when they’ve been inactive for so long?
DirectLife shows that it’s possible. It’s an approach that’s based on proven
research and insight. This brochure examines the scientific basis of DirectLife.

Examining the scientific background of DirectLife
Structured motivation
What’s the best way to keep people motivated to increase their activity level? To address
this issue, we’ve invested many years in scientific research. Of course there are individual
differences. But, in general, we found a number of common factors that motivate people on
a structured basis. These are:
• A clearly defined path, with a distinct start and finish
• Specific, achievable goals
• Continuous tracking of activities ‘every movement counts’
• Personal feedback on the results
• Ongoing support from a live, personal coach
Up until now, no exercise program has been able to combine all of these factors. DirectLife
does. It’s a total concept that really works, based on smart technology and proven psychology.

Before introducing DirectLife, Philips invested in many years of psychological
research. This research helped us determine the critical factors for
successfully influencing long-term behavior : gradual change, direct feedback
and personal coaching. The following pages provide an in-depth look at each
of these factors.
Gradual change
Studies show that the most effective changes in behavior occur step by step. It’s human
nature. People are more motivated to stick with a program that has each new goal within
easy reach. Whatever the objective, we all achieve better results one step at a time. So it’s
important to set realistic yet still challenging goals. That’s why DirectLife is based on each
individual’s unique activity level. After an initial assessment period, specific goals are set.
Each week, the bar will be set just bit higher.
Direct feedback
For those trying to increase their activity level, there’s no better motivation than seeing
results. DirectLife provides this kind of valuable motivation in many ways. Both the activity
monitor and the online program make results clearly visible. The monitor immediately
displays the amount of activity already achieved each day. The online program translates
that activity into the amount of calories burned. Because every bit of activity counts,

DirectLife really works
DirectLife stimulates each person to add more activity to the daily routine. This way, becoming
more active does not become a hassle or time-consuming task. Instead, it‘s something that
comfortably fits the way you live and work. That’s essential for an activity program to be of
long-term value. You don’t have to drastically change … just follow an accessible program
that suits the way you live.

Personal support
Some people need an extra little push to keep going. From a personal coach, for example.
From a psychological point of view, being accountable to another person – and not just to
ourselves – is a powerful incentive to succeed. With DirectLife, it’s the personal coaching
program that really makes the difference. Each participant can count on regular, personalized

guidance to achieve his or her goal. The coach tracks all progress, is always available to answer
questions and, when necessary, can even give an extra motivational push by email. Each
coach is part of an international team of experts in the fields of psychology, communications,
health and wellness. All of the Philips DirectLife coaches have, at minimum, a bachelor’s degree.

The total concept of DirectLife is based onthree principles:
1. Tracking
The scientifically validated activity monitor records every movement in three different
directions. Advanced algorithms translate each and every motion into a specific amount
of calories burned. Of course, the individual’s age, gender, height and weight are also
considered. In this way, each person has a continuous profile of his or her unique activity
level.
2. Monitoring
Activity data is uploaded to a personalized web page. This clearly shows an individual his or
her activity pattern and progress. Everyone, whether they are slightly active or very athletic,
receives a personalized, achievable goal, based on the tracked activity level. It’s all geared to
the individual’s physical condition.
3. Motivating
Studies show that long-term, sustained motivation is a critical factor to success. DirectLife is
based on this principle. It motivates each individual in as many ways as possible. For example,
it sets realistic goals, yet keeps pushing the bar higher, one step at a time. It also shows
results online, and compares them with other participants. But mostly, sustained motivation
is provided by a personal coach. Someone who gives feedback and who will be there
throughout the program to provide encouragement and support. So there’s even more
reason to keep moving more and to never give up.

Measuring movement in three dimensions
The activity monitor features a motion meter that detects and records every movement in
three dimensions. Assuming the monitor is worn properly (and it’s difficult not to wear it
properly), every movement is measured. For example, as soon as the person gets up to
start walking, the upward and forward motions are measured and recorded. And while
cycling or swimming, all leg movements are tracked and recorded. So whatever the activity,
every movement counts.
Advanced algorithms
What makes the DirectLife activity monitor so unique? The key is its use of advanced
algorithms. These algorithms are able to express the activity pattern in terms of the amount
of calories burned. In addition, they take into account individual data such as gender, weight,
height and age. Philips has invested many years of research to perfect these algorithms, in
order to provide an accurate profile of an individual’s total energy expenditure during the
day.

11Enhanced precision
The most accurate way to track someone’s long-term energy use is with the proven ‘doubly
labeled water method’. This method is ideal for determining a participant’s total energy use. The
individual first drinks water that’s been enriched with heavy oxygen and heavy hydrogen. After
a few doses to determine the amount of isotopes in the subject’s urine, the CO2 production
level can be measured. When this is combined with data regarding the carbohydrate, protein
and fat ratios in the fat-burning substrate, the energy use can be calculated. This procedure is
completely harmless for the subject and can be performed on both healthy and sick individuals.
By using this method, we were able to assess the accuracy and precision of the activity monitor.
The result: the activity monitor prototype scored substantially higher for accuracy compared
to other activity monitors. It thereby proved to be a highly capable instrument for tracking and
measuring individual energy use over a 24-hour period.
Scientific research has shown: on average a 28% increase in activity
357 employees
DirectLife was tested with 215 employees in three Dutch companies, as well as with 140
city employees in the town of Gilbert, Arizona, (USA), in co-operation with Arizona State
University.. 43% of the Dutch participants were classified as inactive at the start of the
DirectLife program. Of the American participants, 70% were rated inactive. No incentives
or rewards were offered in any of the trials. Motivation was based solely on intrinsic factors.
An incentive or reward program would certainly increase the participation rate.
12 weeks of tracking
An average of 50% of the participants in the trial completed the full 12-week program.
These individuals tracked and monitored their activity level for 12 weeks, with their data
uploaded to the web site showing their progress.
28% more activity
Participants that were active at the beginning of the program did not significantly change
their activity level over the 12 weeks. However, amongst the initially inactive participants,
25% of them increased their activity level. At the very least, there was a 5% increase in
activity. On average, however, there was a 28% increase at the end of the 12 weeks.
How significant is this? Just a 5% increase for an inactive person means he or she is walking
15 minutes every day instead of sitting. So a 28% increase for this group signifies a substantial
boost in activity. In fact, this level approaches the WHO-recommended amount of 30 minutes
of moderate physical activity, five times a week.

DirectLife proven effective
25% of participants more active
In conclusion: After following the 12-week DirectLife program, 25% of the initial inactive
participants have become much more active. The rest have made a significant step towards
modifying their behavior by raising awareness of their own activity. This last point came to
light during an evaluation after the 12 weeks. Being able to observe and evaluate one’s own
activity level was clearly seen to be a key benefit to the program.
