Functional Neuroimaging Techniques To Examine Falls And Cognition In Older Adults: A Systematic Review, Tia M. Seleem, Raphael Gabiazon
Undergraduate Student Research Internships Conference
Falls in older adults have been attributed to impaired cognition. There is potential for neuroimaging techniques to understand the biological components that are involved in the cognitive processes pertaining to falls. Therefore, the purpose of this systematic review was to analyze how functional neuroimaging can be used to examine the relationship between falls and cognition among older adults. The following five electronic databases were selected to identify peer-reviewed articles in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: 1) Medline (via OVID), 2) PsycINFO (via OVID), 3) CINAHL (via EBSCO), 4) EMBASE (via OVID), and 5) Pubmed. …

Quantifying The Effect Of Age And Contraction Mode On The Force-Velocity-Power Relationship In The Knee Extensors, Justin R. Paturel
Electronic Thesis and Dissertation Repository
PURPOSE: To assess and compare the force-velocity-power relationship (F-V-P) using isotonic and isokinetic knee extensions in 11 younger (19-30y) and 11 older (69-81y) men. METHODS: The construction of the F-V-P curves were attained with each participant performing maximal, explosive knee extensions at 8 different loads (isotonic) and 8 different velocities (isokinetic) on a Cybex HUMAC NORM dynamometer. Maximal voluntary contraction (MVC or Po), maximal shortening velocity (Vmax), maximum power, optimal torque (Popt) and velocity (Vopt) were assessed and compared. RESULTS: The older men were 43% weaker, 18% slower and ~54% less powerful …
