International Journal of Exercise Science: Conference Proceedings
Governing bodies continue to recommend both aerobic and resistance training as part of lifestyle modification, and it is known that exercise is medicine. Load carriage is an activity of daily living, can be an occupational risk, and is a popular method of resistance training. The type of carry could be related to different vascular responses, which may be related to cardiovascular risk. When professionals recommend exercise programs, consideration of the vascular responses in relation to type of carry is important in order to reduce potential risk. PURPOSE: The purpose of this study was to assess vascular health and blood …

Comparing Vascular Measures In Active And Inactive Females With Anterior Or Lateral T-Wave Inversions, Natalya Tasevski, Brianna Wheelock, Deborah L. Feairheller
International Journal of Exercise Science: Conference Proceedings
The presence of T-wave inversions in anterior or lateral leads on an electrocardiogram (ECG) can indicate a range of conditions, from benign to serious, such as myocardial ischemia. While ECG is not a routine screening tool for athletes, and T-wave inversions in anterior or lateral leads are not typically used as the primary diagnostic tool, integrating this with noninvasive vascular health measures like Augmentation Index (Alx@75) and Pulse Wave Velocity (PWV) could provide valuable insights. Both Alx@75 and PWV are measures of arterial stiffness and thus related to cardiovascular risk. Cardiac screening in active and athletic females is under-researched, so …

Speed Has No Correlation To Muscle Volume Of Hip Flexors And Tibialis Anterior Muscles In Division L Football Athletes, Isaiah B. Guymon, Malorie Wilwand, Steven P. Allen, B. Brett Mortensen, Aaron W. Johnson
International Journal of Exercise Science: Conference Proceedings
In American football (AF) a desirable trait is sprint speed that leads to success such as increased touchdowns, yards gained, and number of sacks. Researchers suggest training programs can improve an athletes’ sprint speed. Considering the swing to stance phases, the hip flexors (HF) and tibialis anterior (TA) may impact an athletes’ speed. The HF initiates the swing phase, while the TA muscle dorsiflexes the foot allowing the toes to clear the ground. PURPOSE: To determine if there is a correlation between collegiate football athlete's speed and the muscle volume (MV) of HF and TA muscles. METHODS: This study …

Females Who Have Undergone Acl Reconstruction Exhibit Altered Patellofemoral Joint Alignment And Reduced Contact: Implications For Early Onset Osteoarthritis, Thomas Demirjian, Olivia Tu, Gillian Northrup, Christopher Powers
International Journal of Exercise Science: Conference Proceedings
Reconstruction is the gold standard treatment for those who have experienced a tear of the anterior cruciate ligament. Despite advancements in surgical technique and rehabilitation, a negative consequence of anterior ligament reconstruction (ACLr) is early onset osteoarthritis of the tibiofemoral joint and patellofemoral joint (PFJ). There is evidence that altered patella alignment may be contributory to early onset patellofemoral joint osteoarthritis. A negative consequence of patella malalignment is that contact between the patella and trochlea could be reduced, thereby exposing the joint to elevated stress (force per unit area). PURPOSE: The purpose of the current study was two-fold: 1) …

Measuring Fatigue After Singles Pickleball Tournament Play, Margaret J. Falknor, Steven Kim, James Annesi, George Beckham, Eric Martin
International Journal of Exercise Science: Conference Proceedings
Previously, we measured fatigue from one doubles pickleball match, multiple recreational doubles pickleball matches, and a nine-game doubles pickleball tournament. We found no evidence of neuromuscular fatigue in any of these scenarios. Therefore, doubles pickleball play may not be fatiguing enough to decrease jump performance. Singles pickleball matches may be more fatiguing than doubles play, because players must cover the court and return the ball without a partner. PURPOSE: Our goal was to determine if singles pickleball play would induce neuromuscular fatigue. METHODS: We included healthy adult pickleball players that had no lower body injuries within the past …

Influence Of Region Of Interest Size On Vastus Lateralis Shear Wave Velocity In Individuals With Anterior Cruciate Ligament Reconstruction, Jonathan L. Cardon, Brian W. Noehren, Mckenzie White
International Journal of Exercise Science: Conference Proceedings
PURPOSE: Shear wave elastography (SWE) is an emerging tool for estimating passive muscle stiffness via shear wave velocity (SWV). However, the lack of standardized collection and processing methods limits its clinical utility. One key factor in SWV analyses is the region of interest (ROI), which varies in size across the literature. Individuals post-anterior cruciate ligament reconstruction (ACLR) show changes in muscle quality, making it plausible that ROI size could influence SWE measurements in this population. METHODS: Twenty individuals post-ACLR participated (11M/9F, age = 19 ± 2 years, time since surgery = 5 ± 5 months, body mass index = …

Sex Differences In Cardiac Decompensation Under Moderate Hypovolemic Stress During Exercise, Yusuf I. Rizk, Daisy Hernandez Valadez, Jacob B. Sievers, Youanaa A. Gendy, Areum K. Jensen
International Journal of Exercise Science: Conference Proceedings
Due to higher metabolic demands to the contracting muscles there are significant increases in cardiac output (CO) and peripheral vascular adjustments, thus resulting in an increased arterial blood pressure (BP) during exercise. In general women have higher heart rate (HR), lower stroke volume (SV) and CO compared to men even though they change in a similar fashion during exercise. In response to central hypovolemia, triggered by lower body negative pressure (LBNP), women appeared to have lower tolerance compared to men. However, how women exhibit cardiac alterations to sustained LBNP and exercise differently is unclear. PURPOSE: To investigate sex differences in …
