Six Minute Walk Test Case Study
Measuring the descriptive statistics, heart rate slopes and correlative relations were done in both these phases to make a comparative study using two tailed t-test. To minimize the prediction error of any variables of the 6MWT a stepwise linear regression slopes were used. To validate the regression equation, about 20% of subjects which chosen randomly was used as control group, while the remaining included for predictive equation group. In order to establish the most accurate relation between actual distance, walked by the different subjects and the measured heart rate slopes were also compared. In addition, a comparative perspective with previous studies was done to establish the most dependent factor used during 6MWT.

The 6MWT result reflects functional status, walking autonomy and efficacy of CR on walking endurance, which is more pronounced in patients with low functional capacity (heart failure – cardiac surgery). The 6MWT result is a strong predictor of mortality. However, clinically significant changes and reliability are still subject to debate – probably because of the ambiguity in terms of the target speed (either comfortable or brisk walking).(43). The present study was the first study to vali¬date a protocol to evaluate the beat-by-beat heart rate slopes during 6MWT in healthy male adults. This may be used to obtain the predicted 6MWD for individual subjects aged between 18 and 27 years performing the test for the first time, when using the standardized …show more content…
Thus a significant correlation between 6MWTS and 6MWTD strongly indicating that 6MWTD can be replaced with 6MWTS as a measurement of physical fitness. Distance has a wide variability mainly due to alteration in subjects’ height and other external factor like crowded corridor, so it is not entirely accurate measure of physical fitness(40-42) On the regression analysis, stepwise model used to predict the equations for the distance, 6MWTS and recovery slope. Different prediction values and its equations were mentioned in the result
