Effect of Body Position on Heart Rate Recovery after Sub-maximal Test in Normal Subjects

Gyan et al worked to study the effect of body position on heart rate recovery after sub-maximal six minute walk test in normal subjects. The subjects were tested in two sessions on two consecutive days. The base line values of the subjects were recorded, i.e. the Heart rate. Then they performed the 6-minute walk test and were made to be positioned in the randomized test positions, namely, supine with legs raised to 70 degrees and supine with legs raised to 90 degrees position. Post test measurements of Heart rate were taken with the help of a pulse oximeter, starting from 0 minute to the end of 5^th minute. The conclusion of the study was that Supine with legs raised to 70° leads to a better recovery when compared to Supine with legs raised to 90° position at the end of 1minute, however further studies are necessary to establish it for the rest of the recovery duration.
