Contribution Of The Ankle, Knee, And Hip To Total Lower Extremity Internal/External Rotation, Dylan P. Lidge, Tal Amasay, Vered Arbel
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: …

Harty, Matthew T. Stratton, Jacob Dellinger, Robert W. Smith, Abegale D. Williams, Christian Rodriguez, Sarah White, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Multi-frequency bioelectrical impedance analysis (MFBIA) is able to distinguish between total body water (TBW), extracellular water (ECW) and intracellular water (ICW). Low-frequency currents are thought to primarily pass through ECW, while high-frequency currents pass through all body fluids (i.e., TBW). ICW can then be estimated by subtracting ECW from TBW. As such, MFBIA may have utility for monitoring health conditions resulting in water retention within specific fluid compartments. However, the sensitivity of fluid estimates from MFBIA is not fully established. PURPOSE: To evaluate the effects of acute fluid ingestion on body water estimates produced by a MFBIA analyzer. METHODS …

Water Immersion Skin Wrinkling: The Influence Of Age, Sex, And Adiposity, Jonathon Kava, Daroonwan Suksom, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
From the evolutionary perspective, water immersion skin wrinkling (WISW) is the perceived water drainage to enhance grip in wet conditions. In the modern medicine, it is a noninvasive test of limb sympathetic function and can be used to assess peripheral neuropathy. WISW occurs as sympathetically-mediated contraction of subcutaneous glomus bodies after perturbation of ion concentration in palmar sweat glands. This phenomenon has not been studied well. Currently, it is not clear if common demographic variations (e.g., age, sex, and adiposity) that impact overall cardio-autonomic health status also affect WISW. Purpose: The purpose of the present study is to determine if …
