Effects Of Acute Synchronous Whole-Body Vibration Exercise, Tom J. Hazell Dec 2010

Effects Of Acute Synchronous Whole-Body Vibration Exercise, Tom J. Hazell

Electronic Thesis and Dissertation Repository

Recently, whole-body vibration (WBV) exercise has been gaining interest in the health/fitness community for its reported beneficial outcomes. However, most of these have not been evaluated scientifically leading to some reservation in promoting this new exercise modality. The purpose of this dissertation was to assess the viability of WBV exercise to enhance several selected indices of health.

Study 1 demonstrated that the addition of WBV to an isometric semi-squat in young healthy men (n = 8, 25±2.6 y, 177±7.0 cm, 84±12.1 kg) resulted in increases in femoral artery blood flow and leg skin temperature ...


Mental Blocks: The Behavioural Effects And Neural Encoding Of Obstacles When Reaching And Grasping, Craig S. Chapman Nov 2010

Mental Blocks: The Behavioural Effects And Neural Encoding Of Obstacles When Reaching And Grasping, Craig S. Chapman

Electronic Thesis and Dissertation Repository

The ability to adeptly interact with a cluttered and dynamic world requires that the brain simultaneously encode multiple objects. Theoretical frameworks of selective visuomotor attention provide evidence for parallel encoding (Baldauf & Deubel, 2010; Cisek & Kalaska, 2010; Duncan, 2006) where concurrent object processing results in neural competition. Since the end goal of object representation is usually action, these frameworks argue that the competitive activity is best characterized as the development of visuomotor biases. While some behavioural and neural evidence has been accumulated in favour of this explanation, one of the most striking, yet deceptively common, demonstrations of this capacity is often overlooked; the movement of ...


Contradictory Values And Rules: The Case Of Olympic Sports, Sarah Teetzel Jun 2010

Contradictory Values And Rules: The Case Of Olympic Sports, Sarah Teetzel

XIV IAPh Symposium 2010

This presentation is part of the Gender and Sport track.

This paper examines the concepts of sex/gender, rules, and values using a case study of the eligibility requirements for participating in the Olympic Games. As a global event that attracts more than one billion viewers, the impact of the Olympic Games is substantial. Stemming from a larger project that questions whether rules governing participation in the Olympics function to facilitate the attainment of the values and ideals associated with the Olympic Games, this paper focuses on the tension between the Olympic Charter’s mandate of non-discrimination and specific rules ...
