Why the study?
Are heart-rate and blood pressure responses to maximal acute lower body negative pressure exacerbated compared with maximal graded lower body negative pressure in active older and endurance-trained younger individuals?
Population
19 individuals, comprising active older and endurance-trained younger individuals.

MAP responses to acute LBNP similar by age in active adults; leaves open mechanisms of tolerance differences for prospective study.
Are heart-rate and blood pressure responses to maximal acute lower body negative pressure exacerbated compared with maximal graded lower body negative pressure in active older and endurance-trained younger individuals?
Age alone does not appear to predispose individuals to orthostatic intolerance, as mean arterial pressure responses to acute lower body negative pressure were similar between older and younger individuals.
Hernandez et al. (2010) studied this question.
