Short-Term Cd8+ T Cell Depletion Results In Blunted Liver Inflammation In Old Mice, Konner J. Terrebonne, David J. Buckley, Blessy Joseph, Sunita Sharma, Daniel W. Trott
International Journal of Exercise Science: Conference Proceedings
Advanced age is associated with an increase in basal inflammation of the organs. Previously we have found that T cells accumulate in the liver of old mice. A large proportion of these cells are CD8+ and produce inflammatory cytokines. We have previously demonstrated that CD8+ T cell depletion results in improved glucose tolerance in old mice. However, the mechanisms by which CD8+ depletion improves glucose tolerance is unclear. Therefore, we sought to determine whether pharmacologic CD8+ depletion would result in decreased liver specific inflammation in old mice compared to their old CD8+ intact counterparts. PURPOSE: To test the hypothesis …

The Association And Ability Of Mental Toughness To Predict Cardiorespiratory Fitness In The General Population: A Pilot Study, Adam Crone, Tomas Chapman-Lopez, Ricardo Torres, Meena Meiyyappan, Leroy Bolden, Andreas Stamatis Dr., Jeff S. Forsse
International Journal of Exercise Science: Conference Proceedings
Mental toughness (MT) is associated with performative contexts as the defining attribute that enables individuals to thrive in demanding situations. MT has been linked to varying physiological outcomes in various populations. Cardiorespiratory fitness (CRF) is likewise associated with health and performance outcomes; thereby, assessing CRF remains a vital metric for assessing aerobic performance. What remains unexplored is the relationship between MT and CFT and whether MT can be used as an additional metric to determine CRF. PURPOSE: To determine if MT scores are able to predict CRF levels as indicated by VO2 values. METHODS: Fifty individuals (n = 50, Males …

International Journal of Exercise Science: Conference Proceedings
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 …

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: …

International Journal of Exercise Science: Conference Proceedings
Vitamin D (VD) deficiency is one of the most common deficiencies in the world due to various factors (e.g., lack of sun exposure, dietary considerations). Currently the utilization of exercise may act as an intervention for VD deficiencies to promote increases in VD concentrations in healthy populations. This could largely be due to the loss of calcium from aerobic exercise (AE), leading to a hormonal response [(e.g., parathyroid hormone (PTH)] and the activation of cytochrome’s (e.g., CYP2R1, CYP27B1) responsible for the regulation of VD. Thus, AE may serve as an intervention to promote VD synthesis due to the impacted biological …
No Effect Of Curcumin Supplementation On Inflammatory Response To Resistance Exercise In Resistance-Trained Young Women, Nicholas Lopez, Patrick Schunk, Lydia K. Caldwell, Sarah Deemer
No Effect Of Curcumin Supplementation On Inflammatory Response To Resistance Exercise In Resistance-Trained Young Women, Nicholas Lopez, Patrick Schunk, Lydia K. Caldwell, Sarah Deemer
International Journal of Exercise Science: Conference Proceedings
INTRODUCTION: Resistance exercise can often lead to muscle damage and delayed onset muscle soreness (DOMS). The discomfort associated with these side effects could affect training frequency and intensity and thus optimal chronic adaptation. Further, the use of non-steroidal anti-inflammatory drugs to counteract DOMS may affect muscle adaptation responses. However, curcumin (CUR), a polyphenol found in the spice turmeric, has been shown to attenuate these undesirable effects through its anti-inflammatory and antioxidant properties. PURPOSE: To determine the effect of 8 days (400 mg/d) of a commercially available CUR supplement on muscle soreness and inflammation following fatiguing back squat exercise in resistance-trained …

International Journal of Exercise Science: Conference Proceedings
Hyperglycemia in people with prediabetes and diabetes, if left untreated, can cause serious health conditions and may lead to a diabetic coma. Muscle contraction through conventional exercise is known to increase glucose uptake in cells, thereby decreasing blood glucose levels. Neuromuscular electrical stimulation (NMES) is an innovative approach to contract skeletal muscle involuntarily. Whereas exercise is widely recommended for hyperglycemia management, it is not known whether NMES can be used as an alternative strategy to improve glycemic control. PURPOSE: The purpose of this study was to determine if the use of NMES for muscle contraction can improve glycemic control …

International Journal of Exercise Science 17(4): 54 - 72, 2024. The remarkable popularity of fitness trends like high intensity functional training (HIFT), choreographed high intensity classes (CHIC) and resistance (RT) trainings raises the question on their effect on cardio-respiratory, lactate removal rate, endurance and body composition responses. The purpose of this study was to assess and compare these effects. Ninety-five participants were randomly assigned into 16 weeks of these trainings, five sessions/week. Anthropometric and fitness tests were carried out before training (PRE), after eight (8W) and sixteen weeks (16W). Body composition measures demonstrated significant decrease in body fat percentage ( …

International Journal of Exercise Science 17(4): 1-12, 2024. This study presents somatotype data on a team sport with chronic and diverse sporting demands. The aims were to (1) characterize a somatotype profile for Division II (DII) track and field athletes (n=54) by sex, class, and events; (2) determine if somatotype changed across the season; (3) determine if changes differed based on class or sex; and, (4) assess potential differences in somatotype between sexes. Methods: Anthropometrics (height, weight, body composition, somatotype) were evaluated after a competitive indoor season and immediately before the outdoor conference championships (41 days). Body measurements were assessed …

International Journal of Exercise Science 17(1): 38-53, 2024. The purpose of this study was to investigate whether the ballistic push-up (BPU) is responsive to post-activation performance enhancement (PAPE) after a bench press conditioning exercise using velocity-based repetition control. Additionally, we aimed to evaluate the effects of range of motion (ROM) conditions on subsequent BPU performance. In a randomized crossover design, 18 males performed two conditions (full ROM and self-selected partial ROM) of bench press at 80% of their 1RM until mean concentric velocity dropped 10%. Each participant performed two pre- and six post-test BPUs to assess the PAPE effect. Paired …
