Key result
Systolic blood pressure returned to resting levels after 3 minutes of rest when measured with an automatic sphygmomanometer and after 4 minutes with a mercury sphygmomanometer following 12 minutes of low-intensity walking.

How much resting time is required for blood pressure to return to baseline after low-intensity walking when measured by automatic versus mercury sphygmomanometers in healthy young adults?
In healthy young adults, a resting period of at least 3 minutes is required before measuring blood pressure with an automatic sphygmomanometer after low-intensity walking to obtain accurate resting values.

Suggests device-specific rest intervals post-walking in young adults; hypothesis-generating and requires prospective validation before guideline consideration.
The purpose of this study was to identify the time for young adults to reach resting blood pressure after walking as measured by an automatic and a mercury sphygmomanometer. Methods: Participants were 33 nursing students in their 20s. Blood pressure after walking was measured every minute on both arms simultaneously for a total of 6 times after walking for 12 minutes on a treadmill at ratings of perceived exertion (RPE) of 11. Data were analyzed using paired t-test, Bland-Altman plots and repeated measures ANOVA. Results: Systolic blood pressure after walking was the same as measurements corresponding to resting blood pressure after 3 minutes of resting if measured with the automatic sphygmomanometer and 4 minutes of resting if measured with the mercury sphygmomanometer. Conclusions: In order to measure the resting blood pressure for healthy young adults who performed low-density walking for 12 minutes on flat land, the measurement needs to be made after a resting time of at least 3 minutes in the case of an automatic sphygmomanometer and 4 minutes in the case of a mercury sphygmomanometer.

Choi et al. (2014) conducted an observational in Healthy young adults (n=33). Resting after 12 minutes of low-intensity walking vs. Baseline resting blood pressure was evaluated on Time to reach baseline resting systolic blood pressure (p=<0.001). Systolic blood pressure returned to resting levels after 3 minutes of rest when measured with an automatic sphygmomanometer and after 4 minutes with a mercury sphygmomanometer following 12 minutes of low-intensity walking.
