Impact Of Priming Exercise Load In Vascular Occlusion Test Outcomes, Wonjae Lee, Elizabeth G. Knoll, Joshua L. Keller Feb 2026

Impact Of Priming Exercise Load In Vascular Occlusion Test Outcomes, Wonjae Lee, Elizabeth G. Knoll, Joshua L. Keller

International Journal of Exercise Science: Conference Proceedings

Near-infrared spectroscopy combined with a vascular occlusion test (NIRS-VOT) assesses microvascular function by analyzing tissue oxygen saturation (StO2). StO2-derived outcomes from the NIRS-VOT have been shown to differ across biological sex and fitness and are interpreted as reflecting differences in muscle oxidative capacity, microvascular function, and endothelial health. These differences may be influenced by the accumulation of metabolic byproducts that modulate local oxygen delivery. Exercise performed before a NIRS-VOT can alter metabolic rate, potentially influencing StO2 responses. However, it is unclear whether different submaximal priming exercise intensities affect NIRS-VOT outcomes, particularly when the magnitude of …

Fatigue-Matched Three Different Squats Elicit Blood Lactate Responses In Young Adults, Jiwon Song, Kase Pennartz, Wonjae Lee, Sarah Deemer, Jakob Vingren, David Church, Joshua L. Keller

International Journal of Exercise Science: Conference Proceedings

Resistance exercise (RE) with blood flow restriction (BFR) promotes muscle hypertrophy, using low external loads and may also improve cognitive function and neuroplasticity, possibly by increasing brain-derived neurotrophic factor (BDNF). Lactate accumulation during exercise has been proposed as a potential mediator of exercise-induced increases in BDNF. However, it is unclear whether different RE loading strategies or BFR under fatigue-matched conditions produce distinct lactate responses that could differentially influence downstream neurotrophic mechanisms. PURPOSE: This study examined blood lactate responses for high-load (HL), low-load (LL), and LL-BFR RE in recreationally active young adults. METHODS: Sixteen healthy, recreationally active young adults …
