Effect Of Maurten Sodium Bicarbonate System On 5k Running Performance, Suzanna Q. Navarro, Dustin P. Joubert
Effect Of Maurten Sodium Bicarbonate System On 5k Running Performance, Suzanna Q. Navarro, Dustin P. Joubert
International Journal of Exercise Science: Conference Proceedings
During high intensity bouts of running, acidosis is a contributing factor in muscle fatigue, but sodium bicarbonate can be used to help the body’s natural buffering system by accepting excess hydrogen ions in the blood and muscles. However, gastrointestinal (GI) issues have been an issue with prior ingestion methods in previous studies. Even though past studies have shown a buffering capacity of ~1-5 minutes, the Maurten Sodium Bicarbonate System (MSBS) uses a carbohydrate hydrogel ingestion method that claims to decrease GI tract issues and can sustain the buffering capacity for hours instead of minutes. PURPOSE: Determine the ergogenic effects …

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 …

Previous studies have examined age-related CVD risk factors in small first-responder (FR) groups but haven't explored how age influences non-traditional stress markers and inflammation biomarkers. PURPOSE: To examine age-related differences in non-conventional physiological stress, oxidative stress, and inflammatory biomarkers among FRs. METHODS: Archival data for 170 FRs were analyzed from annual clinical testing. Age groups were 20-39 years and 40 years and above. General linear models (GLMs) were used to evaluate the effects of age group and occupational group on blood and salivary biomarkers: advanced oxidation protein products (AOPP), C-reactive protein (CRP), blood cortisol (CORT), salivary cortisol (sCORT), …
