Schwartz B, Liu H, MacDonald E, Mekari S, OBrien M
Geroscience . 2025 Jan; PMID: 39754009
Health-related quality of life (HRQoL) is inversely associated with all-cause mortality in older adults and may be improved with physical activity and exercise training. The objective of this umbrella review...

Waghorn J, Schwartz B, Shivgulam M, Wu Y, Kimmerly D, OBrien M
Front Sports Act Living . 2024 Dec; 6:1509784. PMID: 39722741
Engaging in muscle strengthening activities (e.g., resistance training) at least twice/week is promoted by (Inter)national movement guidelines. Cardiovagal baroreflex sensitivity (cvBRS) reflects the ability to modulate R-R interval in response...

OBrien M, Schwartz B, Petterson J, Courish M, Shivgulam M, Kimmerly D
Auton Neurosci . 2024 Jun; 254:103193. PMID: 38852226
Purpose: The nadir pressure responses to cardiac cycles absent of muscle sympathetic nerve activity (MSNA) bursts (or non-bursts) are typically reported in studies quantifying sympathetic transduction, but the information gained...

Shivgulam M, OBrien M, Wu Y, Liu H, Petterson J, Schwartz B, et al.
Vasc Med . 2024 Apr; 29(4):381-389. PMID: 38594895
Introduction: Single bouts of prolonged bent-legged sitting attenuate popliteal endothelial-dependent vasodilation (as assessed via flow-mediated dilation [FMD]), which is partially attributed to arterial 'kinking'. However, the impact of knee-flexion angle...

Liu H, Shivgulam M, Schwartz B, Kimmerly D, OBrien M
Am J Physiol Heart Circ Physiol . 2023 Aug; 325(5):H933-H948. PMID: 37594481
Elevated pulse wave velocity (PWV) determined arterial stiffness is a prominent marker of cardiovascular disease (CVD) risk. Exercise training delays the progression of CVD, but existing reviews on the impact...

Schwartz B, Pellerine L, Bray N, Fowles J, Furlano J, Morava A, et al.
J Am Coll Health . 2023 Jul; 73(2):684-690. PMID: 37463523
Objective: Test the hypothesis that smoking, fast-food consumption, and binge drinking were negatively associated with academic performance in Canadian undergraduate students. Participants: Undergraduate students across Canada [ = 411 (335♀)...

OBrien M, Schwartz B, Shivgulam M, Daley W, Frayne R, Kimmerly D
Appl Physiol Nutr Metab . 2023 Jul; 48(11):876-881. PMID: 37429038
Heart rate variability (HRV) is a well-established noninvasive marker of autonomic cardiac control. We test whether time spent sitting (negatively) versus lying (positively) influences vagal HRV outcomes. HRV (10 min...

Shivgulam M, Frayne R, Schwartz B, Wu Y, Daley W, Kimmerly D, et al.
Physiol Meas . 2023 Jun; 44(7). PMID: 37352868
. Approaches to differentiate sitting and lying are available within the default activPAL software from a single thigh-worn monitor. Dual-monitor methods use multiple monitors positioned on the thigh and torso...

Schwartz B, Shivgulam M, Petterson J, Wu Y, Frayne R, Kimmerly D, et al.
J Hum Hypertens . 2023 May; 37(11):1015-1020. PMID: 37185597
Whole-day movement guidelines for improving health, recommend that adults engage in at least 150 min week of moderate-to-vigorous aerobic physical activity and limit their sedentary time. In young adults, higher...

Shivgulam M, Liu H, Schwartz B, Langley J, Bray N, Kimmerly D, et al.
Sports Med . 2023 Apr; 53(6):1161-1174. PMID: 37017797
Background: Dysfunction of the endothelium is a key precursor of cardiovascular disease. Endothelial function, as assessed via the flow-mediated dilation test, is attenuated with chronic disease (e.g., type 2 diabetes...
