Physical Skill Factors Contributing to Success on the Professional Golf Tour

Perceptual and Motor Skills (1991)

Charles L. Nix Robert E. Koslow

Success in professional golf is often measured by scoring average and monetary earnings. It has been suggested that specific physical abilities associated with golfing skills are of primary importance to success at golf. Yet, there is a paucity of literature addressing these relationships. The purpose of this study was to estimate the relationships between success and specific shot-making skills, using data from the 1987 PGA Tour. Correlation and regression techniques indicated that four independent variables (average driving distance, greens in regulation, putts per round, and sand saves) constituted a model of best fit for both measures of success. These four variables explained over 87% of the variance associated with average scores, and over 50% of the variance associated with monies earned. These results support a theoretical model highlighting specific shot-making abilities as crucial to success in professional golf.

Friction Stir Back Extrusion: Tooling and Process Design for AL-1100-O

William J. Emblom Robin Babineaux Charles L. Nix Katie Parr Tyler Saltzman

Friction stir back extrusion has recently been identified as a method for manufacturing stronger, more ductile seamless tubes. The long term goal of the project described here is to miniaturize the process in order to produce highly ductile microscale tubes for biomedical, microscale heat exchanger, and fuel cell manufacturing applications. The process is similar to friction stir welding and processing in that the end of a non-cutting tool rotates against a metal workpiece, heats the workpiece, and creates an ultrafine grain structure. Conventional microtube manufacturing is done by hot direct extrusion using dies with mandrels. After the workpiece passes the mandrels, the tube segments weld together from residual heat. The work described here considers macroscale tooling design prior to down scaling to the multi and microscale. The immediate objective was to develop tooling that can produce 50mm long tubes with 12.5mm outside diameters and 6.35mm inside diameters. Design considerations such as strength, fatigue, buckling, and vibration were considered. This paper documents the development of the tooling design process that was used in order to overcome the various design issues. Tooling failure and analysis is presented as part of the evolution of the tooling design. While majority of the paper discusses the tooling design process, a final design was developed and preliminary results for friction stir back extrusion tests are presented for tubes that are 25 and 50mm long.

Sex-typing of Physical Activities and Success Predictions of Children before and after Cross-sex Competition

Journal of Sport Psychology (1979)

Charles B. Corbin Charles L. Nix

Elementary school children, 20 boys and 20 girls, served as subjects in this investigation designed to determine how children sex-typed each of three different motor activities and to study their success predictions before and after cross-sex competition. Results of the study indicated that both boys and girls sex-typed a motor task requiring strength, speed, and power as a “male” activity, while the two other motor tasks were characterized as “male-female.” The self-confidence levels of girls, as measured by success predictions were lower than boys prior to competition but only for the “male” activity. After cross-sex competition in which girls succeeded as often as the boys, self-confidence of girls was no different than for boys. There were no sex differences in postcompetition state anxiety levels. All subjects regardless of sex were more threatened after competing in a “male” as opposed to a “male-female” activity, and they experienced lower state anxiety following successful rather than unsuccessful competition.

Relations between Preventive Health Behavior and Hardiness

Psychological Reports (1989)

Stephen Nagy Charles L. Nix

To estimate the relationship between hardiness and preventive health behaviors a hardiness scale and a health hazard appraisal were administered to 211 college students. Multiple regression analysis indicated that modest amounts of variance on the hardiness measures were explained by the components of the health-hazard appraisals. Indications are that the concepts of hardiness and preventive health behavior are related and need further clarification.

Development of Content: Influences on Girls' Junior High School Volleyball Success in Practice and Achievement

Perceptual and Motor Skills (1996)

Tracy L. Pellett Charles L. Nix

The purpose of this study was to examine the success of practice by lower- and higher-skilled girls in Grades 7 and 8 in response to different tasks (extension, refinement, and application) throughout an 11-day instructional and practice period for volleyball. More highly skilled girls were more successful than those lower in skill for all skills (forearm pass, set, serve) and tasks. Girls had nearly equal success in practice for different tasks.
