Reference Equation for Prediction of a Total Distance During Six-minute Walk Test using Indonesian Anthropometrics
ABSTRACT: to develop a
reference equation for prediction of the total distance walk using Indonesian
anthropometrics of sedentary healthy subjects. Subsequently, the prediction
obtained was compared to those calculated by the Caucasian-based Enright
prediction equation. Methods: the cross-sectional study was conducted among 123
healthy Indonesian adults with sedentary life style (58 male and 65 female
subjects in an age range between 18 and 50 years). Heart rate was recorded
using Polar with expectation in the sub-maximal zone (120-170 beats per
minute). The subjects performed two six-minute walk tests, the frst one on a
15-meter track according to the protocol developed by the investigator. The
second walk was carried out on Biodex®gait trainer as gold standard. Results:
an average total distance of 547±54.24 m was found, not signifcantly different
from the gold standard of 544.72±54.11 m (p>0.05). Multiple regression
analysis was performed to develop the new equation. Conclusion: the reference
equation for prediction of the total distance using Indonesian anthropometrics
is more applicable in Indonesia.
Key words: six-minute walk
test, reference equation for prediction of total distance, Indonesian
anthropometrics
