Diagnostic Validity Of The Physical Examination Maneuvers For Hip Pathology: A Systematic Review, Nick Pasic, Dianne Bryant, Douglas Naudie, Kevin Willits

Kinesiology Publications

Background: There is a number of physical examination maneuvers used to diagnose hip pathology but the diagnostic validity of these maneuvers is unclear. We conducted a systematic review to evaluate current knowledge regarding the diagnostic validity of the physical examination maneuvers for hip pathology. Methods: We conducted a literature search of the electronic databases MEDLINE, CINAHL, EMBASE, Cochrane, and SPORTDiscus. The methodological quality of each eligible study was assessed and classified according to Sackett and Haynes’ phases of diagnostic research, whereby Phase I and II studies represent proof of concept and Phase III studies are applicable to a clinical setting. …

Effect Of Age On The Hemodynamic And Sympathetic Responses At The Onset Of Isometric Handgrip Exercise., Sophie Lalande, Carolyn P Sawicki, Jacquie R Baker, Kevin Shoemaker

Kinesiology Publications

Cardiac and peripheral vasomotor factors contribute to the rapid pressor response at the onset of isometric handgrip exercise. We tested the hypothesis that age enhances the sympathetic and vasoconstrictor response at the onset of isometric handgrip exercise so that the pressor response is maintained, despite a diminished cardiac function. Twelve young and twelve older (24 ± 3 and 63 ± 8 yr) individuals performed 20-s isometric handgrip exercise at 30, 40, or 50% of maximal voluntary contraction force. Muscle sympathetic nerve activity (MSNA) was measured using microneurography. Mean arterial pressure (MAP) and cardiac output (Q) were assessed continuously by finger …

Evaluating Sport Development Outcomes: The Case Of A Medium Sized International Sport Event, Marijke Taks, Christine Green, Laura Misener, Laurence Chalip

Kinesiology Publications

Research question: This study evaluates sport development outcomes of a medium-sized, one-off, international sport event, while also exploring any strategies and tactics that were implemented with the intention to increase participation or other sport development outcomes. The event under investigation is the 2005 Pan American Junior Athletics Championships.

Research method: Retrospective perceptions of sport development outcomes were explored using event documents, 21 semistructured interviews with key stakeholders, and media coverage of the event.

Results and Findings: The coaching clinic and the new facility were the only two intended tactics expected to intentionally trigger increases in sport participation and development. The …
