Analyzing Sex Differences In Human Performance Through 3d Isotonic Resistance, Jacob M. Cunha

University of the Pacific Theses and Dissertations

Appraisal of scientific literature and understanding continues to grow in the domain of human performance. The effects of sex on concentric resistance training and power output are not well understood. Recent advancements in technology permit more precise measurements of force output and the kinematic changes elicited by training stress. A unique device in capturing kinematic performance output is Proteus Motion. The machine produces an external magnetic load through a protruding apparatus connected to a gyrosphere, which in turn captures concentric movement through all three planes of movement (sagittal, coronal, transversal). The aim of this study is to investigate power output …

Directions Of Attack And Their Effectiveness Of Male Judo Medalists At The Olympic Competitions., Amar Ait Ali Yahia

Baltic Journal of Health and Physical Activity

Introduction: To perform a technical action, the elite judo athlete examines the direction of attack relative to the opponent's body position. This study aimed to analyze and compare the most frequent and effective attack directions carried out by male Olympic medalists. Materials and Methods: A sample of 112 male medalists performed 3,664 attacks in four Olympic tournaments (2004–2016). ANOVA (one factor) determined inter and intra-Olympic comparisons, followed by the post hoc Bonferroni test (p< 0.05). Eta squared η2 and Cohen's d calculated the effect size, respectively. Results: Olympic medalists oriented their attacks principally in right forward (30.5±11.3%), left forward (29.9±10.5%), left backward (18.8±8.1%), and right backward (15.8±6.1%). The effectiveness of right forward (25.7±13.1%) and left forward (26.2±12.5%) dominates left backward (20.5±10.1%) and right backward (15.5±9.7%), respectively. In terms of frequencies and effectiveness, the contribution of secondary directions is negligible. Conclusions: Attacking in eight orientations made the defense vulnerable. Beside the uncertainty and unpredictability, they created more points of imbalance to overcome defensive issues.

Understanding Athletes’ Experience When Transitioning To Life Beyond Sport, Mary L. Dell'arciprete, M Lauren Dell'arciprete

Department of Occupational Therapy Entry-Level Capstone Projects

Discontinuation may be by choice or may be due to an injury; however most collegiate athletes’ sports engagement ends due to graduation causing them to shift their role in an occupation that played a crucial role in their self-identity. Athletes of all levels are challenged in their transition beyond sport and in the adjustment to the various role changes that occur. A significant life event, such as the end of one’s athletic engagement, can cause a loss of identity, purpose, and mental health decline. Former athletes may experience occupational disruption, a temporary inability to adequately engage in meaningful tasks due …
