This investigation attempted to determine whether heart-rate and blood pressure responses to maximal acute lower body negative pressure (LBNP) are exacerbated compared with maximal graded LBNP in active older (n = 9, 70 +/- 7 yr) and endurance-trained younger (n = 10, 23 +/- 3 yr) individuals. Heart rate increased earlier during graded LBNP in the younger group (-40 mm Hg vs. tolerance) and was significantly higher than that of the older adults at the point of tolerance. Mean arterial pressure… CONTINUE READING
