During exercise, lower leg muscle activation has been shown to increase venous return, exercise cardiac output, and arterial blood pressure (BP). Here we investigate BP at rest, with an increase in lower body pressure by unweighting volunteers in a lower body positive pressure treadmill (LBPP-TM). The purpose of this study was twofold; to determine if BP changes while standing over five-minute stages in response to four conditions. Nine participants (21.3±1.8 years) stood in a LBPP-TM in the following ordered conditions: 100%BWset (no unweighting, control), 70%BWset, 35%BWset, and 90%BWset (35%BWset is the greatest unweighted condition). A SunTech® automatic BP cuff measured …

Lower body positive pressure treadmills (LBPP-TM) provide assistive body weight support to the user by forcing air into an inflatable chamber in which the user is secured. The result of this positive pressure can be experienced as a lift to the user. The degree of chamber air pressure (CAP) determines the amount of supportive lift provided with greater and lesser CAP producing more and less lift, respectively. Exercise studies consistently report lower effort perceptions with greater CAP which suggest a reduced physiological and mechanical strain on the body. What is less well known is the effect on resting perceptions of …

Accurate heart rate (HR) measurements are key to exercise prescription. Many portable HR devices are available including the Apple watch. Resting HR from Apple series 3 watch were compared to measurements using a clinal grade Suntech Tango M2 (ST) and Vitalstream Caretaker (VS) pulse monitors. College-aged participants (N = 5) stood in the Alter G treadmill under positive pressures of 70%, 35%, and 90% body weight (BWset), respectively. Heart rates using each device were recorded at min 1, 3, and 5 for each condition. There were no significant differences in resting heart rates measured with the three devices. Average heart …
