Effect Of The Physical Inactivity Duration On Postprandial Lipid Metabolism The Morning After Exercise, Jieting Wang, Chelsea Merseal, Hadi Fareed, Remzi Satiroglu, Edward Coyle

International Journal of Exercise Science: Conference Proceedings

In physically active people (e.g., ~8,000 steps/d), an acute bout of exercise improves postprandial fat metabolism when measured the morning after exercise. However, in people who have been inactive for more than two days, the acute bout of exercise does not improve postprandial fat metabolism as reflected by a greater increase in plasma triglyceride concentration and a reduced whole body fat oxidation. This phenomenon whereby fat metabolism is suppressed by prior inactivity is termed ‘exercise resistance’. PURPOSE: The purpose was to determine if shorter periods (i.e., less than two days) of inactivity (i.e., 12, 24, 36 h) induce ‘exercise …

Comparison Of Oxygen Consumption In 4-Second Sprint Interval Exercise With Varied Intensity And Rest Period, Remzi Satiroglu, Christos Kyrillou, Jieting Wang, Edward Coyle

International Journal of Exercise Science: Conference Proceedings

Sprint interval training (SIT) is usually performed at maximal ‘all-out’ intensities, that are 5-8-times higher than the power needed to elicit VO_2peak. However, the %VO_2peak associated with repeated submaximal power sprints (%P_max), particularly when paired with varying rest periods, remains unknown. Investigating the %VO_2peak in repeated submaximal power sprints is pivotal, enabling the personalization of workout routines to specific training goals.

PURPOSE: The aim of this study was to systematically investigate the acute physiological responses induced by three levels of %P_max intensities (50%, 75%, and 100% of P_max) with three varying …

Maximal oxygen uptake (VO2 Max) is utilized to assess cardiorespiratory fitness (CRF) and performance in various populations. Although VO2max is the gold standard for assessing aerobic performance and CRF, the accessibility, time, and cost are limiting factors for frequent evaluation. Recently, skeletal muscle oxygen saturation (SmO2) has been utilized to characterize the amount of oxygen available in skeletal muscle tissue and the efficiency of oxygen uptake and to serve as an alternative metric to assess CRF. However, minimal research has been conducted to observe the difference in SmO2 location placement between the vastus laterals (VL) and gastrocnemius (GS) during exhaustive …

The Effects Of Different Prolonged Aerobic Exercise Modalities On Physiological Components Of Cardiovascular Drift, Ricardo Torres, Leroy Bolden, Tomas Chapman-Lopez, Jordan Ledington, Meena Meiyyappan, Kaitlyn Gingell, Adam Crone, Brian Leutholtz, Jeff S. Forsse

International Journal of Exercise Science: Conference Proceedings

Cardiovascular Drift (CD) is a physiological phenomenon in which heart rate and VO₂ increase in order to maintain cardiac output as the exercise intensity remains the same. Current understanding of CD indicates that CD is caused by a loss of fluids in combination with a reduced ventricular filling time. Different exercise modalities, such as steady state exercise (SSE) and high intensity interval exercise (HIIE) stress the cardiovascular system differently and cause different adaptations. Currently, no research has been conducted observing components (VO2, HR, and RER) of CD in SSE and HIIE. PURPOSE: To determine if HIIE or SSE alters …

Nutrition Able: A Lecture-Based Intervention To Promote Nutritional Literacy About Protein Intake In Women, Jeffery Bolte, Alejandra Garcia, Jacob Abalos, Jakson Johnson, Alex Joyce, Christopher Hinds, Jared Tuttle, Jeff Svec

International Journal of Exercise Science: Conference Proceedings

Sport performance is influenced by sport-specific requirements for body composition. One major predictor of body composition is protein intake. Higher protein intake tends to cause leaner body composition relative to lower protein intake, especially during caloric deficit. In Bexar County, ~72% of the adult population is overweight/obese and 15.5% are diabetic. This suggests that high protein diet could be a high leverage option in the San Antonio population for optimizing body composition for sport performance. Furthermore, late life sporting activity and protein intake is a primary method for mitigating sarcopenia, osteoporosis, fractures, and accidental death in post-menopausal women. PURPOSE: …
