The Metabolic Cost Of Three Different Modes Of Interval Exercise Versus Continuous Running, Kyle R. Brelsford, Enrrique Reyes, Austin Dunn, James Rowe
International Journal of Exercise Science: Conference Proceedings
Our lab has previously reported that Tabata performed with body calisthenics expends less energy when performed at the same intensity and duration as interval running and continuous running and that EPOC and energy expenditure (EE) during recovery were similar between these 3 exercises. How EE and EPOC would respond to interval resistance exercise remains unclear. PURPOSE: Compare the metabolic response to 4 exercise bouts when performed at a self-selected pace. METHODS: Active men (n=6) and women (n=4) performed 4 separate exercise bouts in a counterbalanced order: total body Tabata (TBT), treadmill running Tabata (TRT), continuous running (CONT) and interval resistance …

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 …
