The purpose of the study was to measure arterial blood pressure with the Finaprestm noninvasive, continuous blood pressure monitor (FBPM) to characterize the continuous blood pressure response during three sets of a 10-repetition maximum double-leg press exercise. Seven recreational weight lifters volunteered for this study. Preliminary sessions determined the 10-repetition maximum (10-RM) for the double-leg press. Subjects lifted to a metronome cadence and were coached to avoid the Valsalva maneuver. During the experimental session, subjects were instrumented for blood pressure measurements by the FBPM. The FBPM used a cuff placed on the middle finger of the right hand, which was maintained at heart level. Subjects completed three sets of 10-RM lifts. Similar to previously reported studies using blood pressure via intra-arterial canulation: within a single repetition, peak pressure was developed as the legs initiated the concentric lift from the flexed position; lowest pressures were developed as the legs became fully extended, and the blood pressure increased with each successive repetition within a set. Additionally, blood pressure increased significantly with each subsequent set (peak systolic blood pressures: set 1- 238±18; set 2 - 268±18; set 3 - 293±21 mmHg). In conclusion, blood pressure responses to the leg press exercise increase with each repetition and also with each successive set, at least for three sets. Therefore, the highest pressures during the leg press were achieved as the lift was initiated from the flexed position, with further increases as repetition and set numbers increased.
