Contribution Of The Ankle, Knee, And Hip To Total Lower Extremity Internal/External Rotation, Dylan P. Lidge, Tal Amasay, Vered Arbel
International Journal of Exercise Science: Conference Proceedings
The nature of the ankle, knee, and hip interaction can profoundly impact the movement patterns of the lower extremities. The ability to internally and externally rotate the lower extremity is essential in order to effectively absorb and apply force. In previous studies, most measurements have been conducted in 2D using a protractor, while mainly evaluating the hip. Dysfunction in any joint throughout the kinetic chain can lead to inefficient movement patterns that can compromise performance and potentially lead to injury. Appreciating the complexity of the lower extremity brings to attention the importance of any segments that are compromised. PURPOSE: …

University of Texas, Austin
An Assessment Of The Potential For Standardizing Various Measures Of Arterial Stiffness, Taha A. Alhalimi, Jisok Lim, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
Arterial stiffness is an independent risk factor for cardiovascular disease. Different measures of arterial stiffness have been used to assess the impacts of exercise training interventions. One of the primary problems faced by investigators conducting systematic reviews and meta-analyses is the lack of standardized methodology to evaluate and compare efficacies of the existing and newly conducted exercise interventions on arterial stiffness. The reference standard measure of arterial stiffness is pulse wave velocity (PWV) while other commonly-used methodologies are ultrasound-derived arterial compliance and distensibility. PURPOSE: To describe standardized equations to convert common ultrasound-based measures of arterial stiffness (arterial compliance, distensibility, ß-stiffness …

Exploring The Potential Role Of Family History Of Hypertension On Racial Differences In Sympathetic Vascular Transduction, Jane N. Cloud, Ben E. Young, Jody L. Greaney, Paul J. Fadel
International Journal of Exercise Science: Conference Proceedings
The prevalence of hypertension in Non-Hispanic Black (BL) men surpasses all other racial groups. Our laboratory has previously demonstrated exaggerated vasoconstrictor and blood pressure (BP) responses to spontaneous bursts of muscle sympathetic nerve activity (MSNA; sympathetic vascular transduction) in young, healthy BL men compared to their Non-Hispanic White (WH) counterparts. Because a family history of hypertension (FHH) further compounds cardiovascular risk, we wanted to begin to explore the potential impact of a positive (+) FHH on sympathetic vascular transduction. Whether a +FHH influences sympathetic vascular transduction in WH and/or BL men remains unknown. PURPOSE: To begin to explore if +FHH …

Arbitrary Metrics In Mental Toughness Research: A Pilot Study Of Female, Ncaa, Division I Basketball Players And Their Strength And Conditioning Coach, Hanna Merrell, Grant Morgan, Jeff S. Forsse, Andreas Stamatis
International Journal of Exercise Science: Conference Proceedings
Over the past two decades, mental toughness (MT) has become one of the most popular concepts in the field of positive psychology and more particularly, in both basic and applied sport psychology. However, the dependence on arbitrary metrics remains one of the major disapprovals of MT research as a whole. Although recently relationships of MT and objective performance indicators have been investigated (e.g., race time), arbitrary metrics still appear inadequate to support answers when it comes to the actual meaning and practicality of self-reported MT scores. Multi-rating, via cross-verification from various sources, can increase the validation of scores of …
