• Health benefits of being
more physically active
• Research examining
exercise and its impact on
cancer survivorship
• How to start being more
physically active

Regular exercise
reaps more
benefits than most
other health habits
because of its
systemic effect on
the human body.

People who exercise regularly are less likely to develop cancer and to
survive longer after a cancer diagnosis
Why is it important to be
physically active?
• Overall individuals who
are more physically
active:
– are more likely to maintain
a BMI >25 kg/m2
– are less likely to develop
chronic diseases,
– are likely to recover faster
from surgeries,
– report a better daily quality
of life
– live longer

Exercise in cancer survivors: What
the science says
Limitations of the research:
• Few well-designed, long-term studies have
been done to date
• Most studies are observational; cannot
draw cause and effect conclusions
• Few studies have examined the effect on
cancer outcomes
• Most studies conducted in one or two
types of cancer
Exercise in women with breast cancer,
Stage I, II, III, Holmes et al, 2006
•
•
•
Research to study the relationship between exercise and brca survival
(stages I,II, and III) in 4400 women, Nurses Health Study (121,700)
since 1976
Results-women in any category of activity higher than 1hr/wk, had
better survival rates compared with those exercising less.
Comparing the highest with lowest categories of PA, there was a 2640% lower relative risk of adverse outcomes in those in the highest
category of PA. (Association particularly apparent in women with
hormone (+) tumors, and those with Stage III cancer)

Research-Exercise in
colon cancer survivors
• Meyerstadt, et al (2006)-2 studies in colon
cancer survivors
• Examined association between PA after
diagnosis and mortality (Nurses Health
Study data).
• Results-significant reduction in cancer
mortality for those exercising > 5-6 hours
/week. (Independent of pre-dx PA)
Relevant issues remain:
• What dose is required
for benefits?
• Is there benefit across
types of cancer?
• What are the
characteristics of
individuals most likely
to exercise?
• Is the positive effect of
exercise exerted
through weight control
or some other
molecular or metabolic
mechanism?
Determinants of exercise in
patients with multiple myeloma
• Jones et al. (2006) studied the determinants
of intention to exercise in patients (n=77).
• In examining demographic, medical and
social/cognitive factors results were:
– Being more likely to see exercise as beneficial
and
– Perceiving exercise being easy rather than
difficult were the strongest predictors
• Neither age, race, gender, nor stage of
cancer was related.
ACS Guidelines for Exercise
• Adults- Engage in at least 30 minutes of
moderate to vigorous physical activity,
above usual activities, on 5 or more days
of the week, 45-60 minutes are preferable
• Children and teens-Engage in at least 60
minutes/day of moderate to vigorous
physical activity at least 5 days/week
• American Cancer Society-www.cancer.org
How to start being more
physically active
• Make the decision
• Determine a schedule
• Use a calendar or a
daytimer
• If you are currently
sedentary, walking is
a good choice
• Start with walking 15
minutes 3 days/week
• A pedometer is useful
Exercise Intervention
• To address energy balance in African American
breast cancer survivors we developed a
cognitive behavioral, theory based walking
intervention, Walking Counts! (Wilson, et al).
• Study tested feasibility, recruitment/retention,
use of pedometers, attending weekly classes,
and impact of self-assessment, education,
motivation.
• Test for effect on level of exercise,
anthropometric, attitudinal and related measures
in a group of African American breast cancer
survivors recruited for the study in Richmond.

Summary
• Exercise has multiple benefits to mental and
physical health
• Individual who exercise have more positive
health outcomes
• Research with cancer survivors has shown that
survivors who exercise after diagnosis may have
fewer recurrences and better clinical outcomes
• Walking is a recommended activity-work towards
a goal of 30 minutes/day and then 10,000 steps
or 60 minutes long term
Include daily exercise on
your path to optimal health!
