The purpose of this study was to first examine the role of coaches, peers, and significant others in the development of relatedness as it applies to the motivation of adult Master swimmers, and second to develop recommendations for coaches. The participants in this study were 87 Masters swimmers from the Wasatch Front region of Utah in the counties of Davis, Weber, Utah, Wasatch, Salt Lake, and Summit. Participants in this study were registered members of United States Masters Swimming(USMS) and were spread across eleven age-group classifications in five-year increments and ranging in age from 18 to 74. There were 43 adult males and 44 adult females that participated in completing an open-ended response questionnaire. The results of this study show that relatedness, fostered by coaches, peers and significant others, plays a key role in getting and keeping adult Masters swimmer in the water to train and compete.

Note:

Microorganisms swimming in their natural habitat interact with debris and boundaries, which can modify their swimming characteristics. However, the boundary effect on swimming microorganisms have not been completely understood yet, and is one of most active areas of research. Amongst microorganisms, unicellular ciliates are the fastest swimmers and also respond to a variety of external cues. We choose Paramecium multimicronucleatum as a model system to understand the locomotion of ciliates. First, we explore the effects of boundaries on swimming modes of Paramecium multimicronu- cleatum by introducing them in 2D films and 1D channels. The geometric confinements cause the Paramecia to transition between: a directed, a meandering and a self-bending behaviors. During the self-bending mode the cell body exerts forces on the walls; which is quantified by using a beam bending analogy and measuring the elasticity of the cell body. The first inves- tigation reveals the complicated swimming patterns of Paramecium caused by boundaries. In the second study we investigate the directed swimming of Paramecium in cylindrical capillaries, which mimics the swimming of ciliates in the pores of soil. A finite-sized cell lo- comoting in extreme confinements creates a pressure gradient across its ends. By developing a modified envelop model incorporating the confinements and pressure gradient effects, we are able to predict the swimming speed of the organisms in confined channels. Finally we study how Paramecium can swim and feed efficiently by stirring the fluid around its body. We experimentally employ "-Particle Image Velocimetry to characterize flows around the freely swimming Parameicum and numerically use Boundary Element Method to quantify the effect of body shapes on the swimming and feeding process. Results show that the body shape of Paramecium (slender anterior and bulky posterior) is hydrodynamically optimized to swim as well as feed efficiently. The dissertation makes significant advances in both experimentally characterizing and the- oretically understanding the flow field and locomotion patterns of ciliates near solid bound- aries. / Ph.

The purpose of the present study was to examine goal setting strategies, locus of control beliefs and personality characteristics of swimmers (108 males and 111 females) from top twenty 1999 NCAA Division IA programs. Three questionnaires were completed: (a) Goal Setting in Sport Questionnaire (GSISQ: Weinberg, Burton, Yukelson, & Weigand, 1993), (b) the Internal, Powerful Others, Chance Scale (IPC: Levenson, 1973), and (c) the compliance subscale and six conscientiousness subscales from the NEO Personality Inventory-Revised (NEO PI-R: Costa & McCrae, 1985). Descriptive statistics from the GSISQ indicated that most of the swimmers set goals to improve overall performance (51%) and set moderately difficult goals (58%). Results associated with the IPC scale revealed that most of the swimmers attributed their sport performance to internal factors. Results pertaining to the NEO-PI-R indicated that most swimmers were highly conscientious, disciplined, purposeful, and determined.

The problem with which this study was concerned was that of comparing three methods of executing the competitive breaststroke turn and their effects on swimming fifty yards. The turns utilized were the AAU, NCAA, and somersault. A related purpose was that of analyzing the time a breaststroke competitor was to be submerged on the glide following the turn. One hundred four male, senior swimmers from teams in the Arkansas AAU were rated on five components of the breaststroke. Twenty-nine advanced and thirty novice breaststrokers were selected from this group to participate in this study. The subjects were timed for a distance of fifty yards using, in order, the AAU, NCAA, and somersault turns.

Zetisky Jonathan V 9213052F zeds@telkomsa.net Master of Science in Medicine Faculty of Health Sciences M.Sc (med) Prof Rogers, G / Development in triathlon at the elite level can be improved by knowing the physical, physiological and anthropometrical characteristics of current elite triathletes and single sport athletes, and isolating those factors that contribute to high levels of performance. Much research on this topic has been done with regard to the single sport disciplines of running, swimming and cycling. However, less is known about triathletes. The primary purpose of this study was therefore to see whether and how triathletes differ from the single sport athletes in the disciplines of swimming, cycling and running, and by so doing, to develop a profile of an elite South African triathlete. Thirty-four subjects (triathletes: n = 12; runners: n = 8; swimmers: n = 6 and cyclists: n = 8) were measured for the physical characteristics of age, mass, height, body fat and lean body mass. Anthropometric measurements (skinfolds, bone breadths and girths) were also taken along with the physiological components of VO2 maximum (maximal oxygen consumption) and running economy. Muscle strength and endurance were also measured. The results showed that triathletes do not differ significantly from the single sport athletes (swimmers, cyclists and runners) in any of the components measured. In fact, they are generally most similar to cyclists in all of the categories measured and in each of these, lie between runners and swimmers. Runners and swimmers however, were significantly different (P<0.05) from each other in terms of mass (kg), lean body mass (kg) and maximal oxygen consumption (ml O2/kg.min-1). 3 No significant differences were noted between the triathletes, swimmers, cyclists and runners in endomorphy, mesomorphy and ectomorphy somatotype ratings. Swimmers (2 – 3,9 – 2,7) and cyclists (2 – 4 – 2,8) as well as the triathletes (2 – 3,8 – 2,8) fall into the ectomorphic-mesomorph somatotype while runners (1,8 – 3 – 3,5) on the other hand, were classified as mesomorphic-ectomorph. The study therefore suggests that no single physical, physiological or anthropometrical factor determines successful performance. Rather, it is a blend of physical and physiological traits observed in the single sport athletes that makes a successful triathlete.

Introduction (Context): The purpose of this study was to measure and correlate pectoralis minor length (PML) and acromiohumeral distance (AHD) in male and female collegiate swimmers, overhead athletes, and a control group. Methods: Participants underwent assessment of pain related to impingement syndrome with special tests (painful arc, external rotation resistance, empty can, and Neer's impingement test), as well as range of motion, measurement of PML, and measurement of subacromial space via ultrasound. Design: Cross-sectional, correlational study. Setting: University modalities laboratory. Participants: 60 healthy subjects (20 swimmers, 20 overhead athletes, 20 controls, age = 21.5 ± 2.4 years; height = 178.7 ± 10.2 cm; weight = 76.9 ± 13.4 kg; BMI = 24 ± 3.4) with 20 subjects in each of the 3 experimental groups: swimmers, overhead athletes, and control. Results: Height-normalized PML for both the dominant and nondominant arms was positively and weakly correlated with AHD at 0° (r = .361; p = .002; (r = .277; p = .016) respectively. Differences were shown between groups in AHD at 0° but no differences were shown in PML. Conclusions: There was a weak positive relationship between height-normalized PML and AHD at 0° both in dominant and nondominant shoulders. Swimmers and overhead athletes were observed to have more AHD than controls.
