Cost-Effectiveness Of Cardiovascular Screening For Prevention Of Sudden Cardiac Arrest In High School Athletes, Abbey Santanello
International Journal of Exercise Science: Conference Proceedings
Sudden cardiac death (SCD) is rare, but each death has a significant impact on the victim’s family and community. Pre-participation physical evaluation is a critical step in preventing SCD, but studies indicate that proper screening is infrequently performed. The inclusion of electrocardiogram (ECG) and/or focused echocardiogram in screening is controversial. The purpose of this study is to determine the value of integrating ECG and echocardiography with cardiac-focused history for screening. Screening was offered with parental consent to athletes at 7 high schools in Staten Island. Students completed a questionnaire about cardiac symptoms, physical exam abnormalities, and family history. Each screening …

Body Mass & Muscle Weight Following Volumetric Muscle Loss Injuries, Kyndal Jones, Jj Payne, Matt Mangus, Jake Sorensen
International Journal of Exercise Science: Conference Proceedings
Volumetric muscle loss (VML) is the traumatic or surgical loss of a significant amount of skeletal muscle, resulting in decreased function and regenerative abilities. Despite the decrease in function, when one muscle is injured or removed, there is typically a compensatory response in the surrounding muscles that promote hypertrophic adaptations. PURPOSE: The purpose of this study was to observe how surgery impacts body mass and the weight of certain muscle groups 6 weeks after a VML injury to the tibialis anterior (TA) muscle, with particular interest in determining if a hypertrophy response occurs in surrounding muscle groups. METHODS: …

Effect Of Barefoot Strength Training On Time To Stabilization And Ankle Inversion During Single-Leg Drop Landing In Ncaa Division I Female Volleyball Players, Logan Manley, Sydney Leisz, Trevor Gillum, William Boyer, Jared Coburn
International Journal of Exercise Science: Conference Proceedings
When volleyball players land from a jump, there is a large energy transfer that occurs throughout the kinetic chain. Time to stabilization (TTS) is a measure that represents the ability to control ground reaction forces (GRF) upon landing. Ankle inversion (INV) angles upon landing also represent the risk of ankle injury due to forceful inversion of the ankle joint. Prior research has found differing risk for injury when accounting for volleyball sport-specific limb dominance and inter-limb asymmetries. A joint is weakened when exposed to repetitive landing movements, putting it at a higher risk of injury due to continual absorption of …

Shear wave elastography (SWE) has been used to assess muscle stiffness, but there is limited information on acute changes over time, particularly regarding how heating and stretching affect the intrinsic stiffness of the gastrocnemius. PURPOSE: to compare stiffness between neutral and relaxed ankle positions for the lateral head of the gastrocnemius (LG) and to evaluate whether passive heat alters muscle stiffness. A secondary aim is to assess stiffness changes in the LG over a 10-minute stretch, both with and without heat. METHODS: Thirteen subjects (4 men and 9 women) participated in this study. The mean age was 21.5 …

The systolic blood pressure (SBP) during prescribed exercise (ExSBP) represents cardiovascular strain during tasks of daily living and is predictive of future cardiovascular disease. Individuals with greater body mass reportedly have a greater increase in ExSBP when exercise is performed at an absolute intensity (e.g., walking 2.5 mph). It is unclear if this exaggerated response persists when exercise is performed at the same intensity relative to one’s fitness (e.g., % Lactate Treshold). PURPOSE: Determine if individuals with a high body mass index (BMI) exhibit an exaggerated ExSBP when exercise is prescribed with respect to personal fitness level. METHODS: Thus …
