actually there is a tonne of data on this do a forward and

OBJECTIVE: To examine the relationship between
pedometer-determined ambulatory activity (steps/day) and body
composition variables body mass index (BMI) and percentage
body fat). DESIGN:: Secondary analysis of a cross-sectional
objective activity monitoring study for up to 21 consecutive
days. SUBJECTS: A total of 109 apparently healthy adults
(eight African American males, 23 African-American females, 33
Caucasian males, 45 Caucasian females), age 44.9+/-15.8 y,
BMI=26.9+/-5.1 kg/m2. MEASUREMENTS: Pedometer-assessed
ambulatory activity (steps/day), height and weight, and
percentage body fat by bioelectrical impedance. RESULTS:
Analyzed as both a continuous and a categorical variable
(determined using 25th and 75th percentiles for distribution
for steps/day), ambulatory activity was consistently related
to body composition variables. Steps/day was inversely
correlated with BMI and percentage body fat (r=-0.30, and
r=-0.27, respectively, both P<0.01). The consistency of the
relationship was also evident when examined using accepted BMI
cut-off points for normal-weight, overweight, and obese
categories. CONCLUSIONS: Individuals in this small sample with
values greater than approximately 9000 steps/day are more
frequently classified as normal weight for height. Individuals
with values less than approximately 5000 steps/day are more
frequently classified as obese. These findings require further
corroborative investigation but provide preliminary cutoff
points for identifying individuals at risk who may benefit
from appropriate physical activity intervention.
