PHYSICAL EXAM: The athletic training staff assessed the right shoulder immediately after injury and tested his shoulder strength. After examination the athletic training staff came to the conclusion that it was an AC sprain, …
The Relationship Between Cerebral Pulsatility Index And Indices Of Cerebral Vascular Autoregulation, Ken Perry, Alison Ortiz, John Kolade, Prarthi Shah, R Matthew Brothers
The Relationship Between Cerebral Pulsatility Index And Indices Of Cerebral Vascular Autoregulation, Ken Perry, Alison Ortiz, John Kolade, Prarthi Shah, R Matthew Brothers
International Journal of Exercise Science: Conference Proceedings
Reduced cerebral vascular function/health is a precursor to various cerebral vascular diseases and neurocognitive conditions including stroke, cognitive decline, and Alzheimer’s disease and related dementias. Cerebral vascular pulsatility index (PI) is a measure of cerebral vascular stiffness and is positively correlated with many of the aforementioned conditions. In addition, cerebral autoregulation, the ability to maintain cerebral blood flow relatively constant in the face of changes in arterial blood pressure, is also impaired in many of the aforementioned conditions. However, to the best of our knowledge the relationship between these two commonly assessed parameters of cerebral vascular function/health remains unknown. PURPOSE …

Responses Of Inflammatory Biomarkers In Circulation And Peripheral Blood Mononuclear Cell To Maximal Exercise With Nasal Breathing, Vineet K. Paidisetty, Jose M. Moris, Yunsuk Koh
International Journal of Exercise Science: Conference Proceedings
There is growing interest in utilizing nasal breathing (NB) in exercise routines to improve performance. However, there is uncertainty on the impact of such exercise on inflammatory biomarkers in circulation and peripheral blood mononuclear cells (PBMCs), which play a significant role in immune response. PBMCs can undergo functional changes from interactions with exercise-related cytokines, potentially inducing a more efficient immune response. PURPOSE: This study examined the acute responses of pro- and anti-inflammatory cytokines in circulation and PBMCs following a maximal exercise with NB. METHODS: Eleven physically healthy, sedentary men (age = 20.63 ± 1.36, BMI = 26.03 ± 3.16 kg/m …
'Super' Shoes Do Not Affect Jump Performance, Marshall Tousant, Francesca Aquilino, Ernesto Balderrama, Chaehyun Byun, Raquel J. Cavazos, Shelby Gerner, Cheyenne Martinez, Austin Riffe, Michael D. Oldham, Vipa Bernhardt
'Super' Shoes Do Not Affect Jump Performance, Marshall Tousant, Francesca Aquilino, Ernesto Balderrama, Chaehyun Byun, Raquel J. Cavazos, Shelby Gerner, Cheyenne Martinez, Austin Riffe, Michael D. Oldham, Vipa Bernhardt
International Journal of Exercise Science: Conference Proceedings
Marathon run times have been dropping rapidly in recent years and many believe that ‘super’ shoes are the reason. ‘Super’ shoes are made with light-weight, highly compliant and resilient midsole foam and a rigid carbon fiber plate. The material used for the foam can store mechanical energy, i.e., compliance, and return the energy, i.e., resilience (Worobets et al, 2014). The carbon fiber plates increase bending stiffness and changes the leverage of the ankle and metatarsophalangeal point, such that the body is propelled upward and forward (Roy & Stefanyshyn, 2006). Indeed, there is evidence that ‘super’ shoes can improve running economy …

Effects Of Endurance Training On Skeletal Muscle Mass And Inflammation In A Rat Model Of Heart Failure, Aaron Garcia, Dillon Harris, Quinten Pigg, Daniela Sayuri Inoue, Mariana Janini Gomes
International Journal of Exercise Science: Conference Proceedings
Chronic disease states including heart failure (HF) often lead to reduced physical activity, resulting in disuse and low-level systemic inflammation, which contribute to the decline in muscle mass and function. An important goal of therapy in HF patients is to counteract or prevent the development of skeletal muscle alterations in order to restore a normal functional capacity. Exercise is an established means of improving exercise capacity and quality of life in patients with HF. Therefore, we aimed to evaluate the impact of an endurance program on skeletal muscle mass and inflammation in a rat model of pulmonary arterial hypertension (PAH)-induced …

Taylor Iv, Jaci Davis, Katelyn Kolodziejczyk, Alyssa Faterkowski, Nikolas Keratsopoulus, Robert Mills, Jayden Widener
International Journal of Exercise Science: Conference Proceedings
Basketball is a fast, explosive sport where a high vertical jump (VJ) is extremely beneficial. Research has shown that greater amounts of lean mass have been associated with higher force output, and therefore higher VJ. PURPOSE: The purpose of this study is to examine the correlation of overall total lean body mass percentage (TBLM%) and lower body lean mass percentage (LBLM%) and Body fat percentage (BF%) with VJ in previously untrained collegiate D-III women basketball players. METHODS: Fourteen females (20±1.3 years, 170.68±8.76 cm, T1 BF% 28.68±5.38, T2 27.11±5.12) basketball team participated in this study. Athletes were tested on two different …

Blood Pressure Variability In Young Male Adult Habitual Vapers, Rie V. Conley, Claire E. Kissell, Ziba Taherzadeh, Danny Dubroy, Benjamin E. Young, Ziyad Ben Taleb, Paul J. Fadel
International Journal of Exercise Science: Conference Proceedings
The use of e-cigarettes (i.e., vaping) has risen dramatically in the last few years. Vaping is more appealing and accessible to young people than traditional smoking. The ease of use can increase the frequency of vaping, which may increase the amount of nicotine consumed. Nicotine is a potent vasoconstrictor that may also affect blood pressure (BP). Indeed, previous studies have shown that traditional cigarette smoking increases BP variability. This is noteworthy because elevated BP variability has been shown to predict future development of cardiovascular disease. However, whether habitual vaping influences BP variability remains unknown. PURPOSE: To test the hypothesis …

Enhancing Oxygen Uptake Efficiency Through Nasal Breathing In Aerobic Exercise, Kylie Allen, Jose M. Moris, Ryan Curtis, Christian J. Chang, Brandon Arnold, Yunsuk Koh
International Journal of Exercise Science: Conference Proceedings
An individual’s ability to use oxygen to sustain aerobic performance, as denoted by the oxygen uptake efficiency (OUE), is calculated by dividing oxygen uptake (VO2) by ventilation (VE). Whether nasal breathing (NB) during exercise would improve OUE more significantly compared to combined breathing (CB) remains uncertain. PURPOSE: To determine the effects of utilizing NB during exercise on OUE. METHODS: Fourteen males (age: 20.57 ± 1.22 yrs; BMI: 26.03 ± 3.16 kg/m2) were randomly assigned to the NB (n = 8) or CB (n = 6) group for a 4-week supervised aerobic exercise intervention conducted four times …

Relationship Between Intestinal Permeability And Microvascular Responses In A High-Risk Hispanic Population Of The Rio Grande Valley, Sophia M. Moreno, Alissa Olvera, Abigail Gomez, Ryan Russell, Melody Cantu, Andrea Toledo, Yu Lun Tai
International Journal of Exercise Science: Conference Proceedings
The Rio Grande Valley (RGV) has ~3x higher rates of diagnosed cardiovascular disease (CVD) and type 2 diabetes (T2D) than the US, which combine to be the leading cause of preventable death in the developed world. Microvascular blood flow (MBF) responses are an early indicator of vascular insulin resistance, and is blunted with obesity, T2D, and those at high risk for T2D. We have previously shown that apparently healthy people in the RGV display impaired MBF responses, helping explain the disparities noted with chronic disease. However mechanisms explaining this early vascular insulin resistance remain unexplored. Recent studies indicate that increased …

Exercise Pressor Response In Hispanic Adults With Family History Of Hypertension, Ashlesha D. Dalve, Justo Perez Iii, Ruby A. Nyarko, Jasdeep Kaur
International Journal of Exercise Science: Conference Proceedings
Family history of hypertension (FHH), being an unmodifiable risk factor, increases probability of developing hypertension and other cardiovascular diseases. The prevalence of hypertension in Hispanic/Latino (H/La) males is 50.3%, while it is 48.9% in non-Hispanic white (NHW) males and 57.5% in non-Hispanic black (NHB) males. Among adolescents aged 8 to 17, H/La youth has the highest incidence of hypertension as compared to all other races. It is evident that young normotensive adults with positive family history of hypertension (+FHH) exhibit exaggerated exercise pressor response. Additionally, a higher sympathetic activity to cold pressor test (CPT) was found in normotensive NHB adults …

Systemic Inflammation Persists In Rats With Heart Failure After A Short-Term Endurance Training Protocol, Quinten Pigg, Dillon Harris, Aaron Garcia, Daniela Sayuri Inoue, Mariana Janini Gomes
International Journal of Exercise Science: Conference Proceedings
Exercise has been shown to produce an anti-inflammatory response and an increased exercise tolerance in heart failure (HF) patients. In rats, monocrotaline (MCT) leads to pulmonary arterial hypertension-induced HF (PAH-HF), resulting in exercise intolerance and chronic inflammation. However, little is known about the effects of endurance training in rats with PAH-HF induced by monocrotaline. PURPOSE: To investigate the effects of an endurance training protocol on systemic inflammatory markers and exercise tolerance in rats with HF. METHODS: 30 male Wistar rats (~250g) were randomly divided into 4 groups: control untrained (CU); control trained (CT), PAH-HF untrained (HFU), and PAH-HF trained (HFT). …

Maximal Isometric Contraction In Skeletal Muscle Of Endurance Trained Rats With Heart Failure, Dillon Harris, Jacob Kendra, Quinten Pigg, Shadi Golpasandi, Aaron Garcia, Daniela Inoue Yoshimura, Aaron Morton, Mariana Janini Gomes
International Journal of Exercise Science: Conference Proceedings
Heart failure (HF) leads to debilitating skeletal muscle dysfunction and atrophy, with exercise tolerance (ET) remaining a crucial indicator of clinical, practical, and mortality-based outcomes. To simulate these comorbidities, monocrotaline (MCT) is a pharmacological agent typically used to aid in replicating experimental models of right ventricle HF. PURPOSE: To investigate the viability of moderate-intensity aerobic training to preserve skeletal muscle function and ameliorate muscle atrophy in MCT-induced HF. METHODS: Thirty 8-week-old male Wistar rats were randomly divided into sedentary (SED) or trained groups (EX; 30min/day treadmill running sessions, 5 days/wk, for 4 weeks) at 60% intensity determined by a maximal …

Cisplatin is a chemotherapeutic agent known to cause skeletal muscle atrophy and cachexia; however, the long-term effect of cisplatin on skeletal muscle adaptations to exercise remains unclear. PURPOSE: The purpose of this study was to assess if prior administration of a clinically relevant cycle of cisplatin blunts exercise adaptations in response to 8 weeks of exercise training. METHODS: Female CD2F1 mice, n = 7-8/group, were treated with 5 mg/kg of cisplatin, or vehicle, once per week for 4 weeks, then given a 4-week washout. Afterwards, mice were singly housed and subjected to either progressive weighted wheel running (PoWeR) …

Traditional resistance training programs recommend training loads of at least 60% 1-repetition maximum (1RM) to stimulate muscle hypertrophy within 3 weeks. Low-load blood flow restricted (BFR) resistance training (RT) has implications in rehabilitation since this modality has shown comparable muscle hypertrophy to high-load RT at intensities as low as 30% 1RM. However, the recommended effects of BFR on muscle size in various musculature throughout an intervention has not been thoroughly examined. PURPOSE: Therefore, the purpose of this investigation is to measure temporal changes in muscle thickness (MT) on the tibialis anterior (TA) throughout 4 weeks of BFR training. METHODS: Thirteen …

Forced vital capacity (FVC) and its two components [forced expiratory volume during the first second (FEV1.0) and peak expiratory flow (PEF)] denote lung function and can be affected by respiratory compliance. Performing an aerobic exercise with nasal breathing (NB) could be beneficial to elicit more significant FVC improvements compared to combined breathing (CB). PURPOSE: To determine if four weeks of aerobic training with NB could improve FVC more than CB. METHODS: Fourteen young males (age = 20.57 ± 1.22 yrs and BMI = 26.03 ± 3.16 kg/m2) participated in the 4-week supervised exercise intervention, consisting of …
