An analysis of selected kinematic variables in national and elite male and female 100-m and 200-m breaststroke swimmers 总被引:2,自引:1,他引:1
The kinematic analysis of competition breaststroke swimming has tended to focus on the mean values of swimming speed, stroke rate and stroke length; values in individual lengths, as well as the start, turns and finish, have largely been ignored. This study includes all such variables and aims to improve the coach's holistic understanding of breaststroke racing by determining the relationships and differences between and within these selected kinematic variables. We also compare 100-m events with 200-m events to determine if there are characteristic differences between them. Competitive breaststroke swimming performances in 100-m events (males: n = 159, finishing time = 65.05 +/- 2.62 s; females: n = 158, finishing time = 74.04 +/- 3.66 s) and 200-m events (males: n = 159, finishing time = 141.47 +/- 6.15 s; females: n = 158, finishing time = 158.66 +/- 7.87 s) were collected and analysed from 12 world, international and national championships. The better 100-m and 200-m breaststroke swimmers were found to demonstrate greater competency in the kinematic variables measured, except stroke kinematics, which were unique to each individual. These findings suggest that coaches should place emphasis on all of the kinematic components in training and that they should attempt to identify the stroke rate to stroke length ratio most appropriate for the individual. Finally, characteristic differences do exist between the 100-m and 200-m events, which has implications for how swimmers might train for each event. 相似文献

The University of Oklahoma Health Sciences Center (OUHSC) Library mailed a MEDLINE End User Practice Survey Form to 310 health professionals who had attended MEDLINE seminars supported by a two-year NLM grant. The survey sought to determine how many respondents had obtained NLM codes, reasons for not obtaining a code, searching time done since the seminar, differences in the use of information since taking the seminar, factors helpful in successful searching, and factors contributing to frustrations. The most prevalent reasons for not obtaining a code were lack of a microcomputer and modem, infrequent use of MEDLINE, cost, lack of time, complications, and ability to obtain free searches. 相似文献

A student's expectation for a positive outcome for their future career development is referred to as career optimism. Career Services, a common university department, utilizes the social cognitive career theory (SCCT) to understand how students form career interests and make educational and vocational choices. Then Career Services can assist students in finding a career that matches their interests. We hypothesize that students' perception of the assistance provided by the Career Services department when the SCCT is applied, impacts the student's career optimism. In addition, we hypothesize, and results support, that different factors, such as a student's chosen major, impact student perception of Career Services and career optimism. 相似文献

The study examined the moderating role of children's affect-biased attention to angry, fearful, and sad adult faces in the link between interparental conflict and children's distinct forms of involvement. Participants included 243 preschool children (Mage = 4.60 years, 56% female) and their parents from racially (48% African American, 43% White) and socioeconomically (median annual household income = $36,000) diverse backgrounds. Data collection took place in the Northeastern United States (2010–2014). Utilizing a multi-method, multi-informant, longitudinal design, attention away from anger selectively amplified the link between interparental conflict and children's subsequent coercive involvement (β = −.15). Greater attention to fear potentiated the pathway between interparental conflict and children's later cautious (β = .14) and caregiving involvement (β = .15). Findings are interpreted in the context of environmental sensitivity models. 相似文献

Supplemental reading instruction provides a way to improve the reading outcomes of students at risk for reading difficulties and to meet the challenges produced by increases in student diversity in today’s classrooms. The research–based intervention described in this article includes intensive, explicit, and systematic reading instruction in five areas: fluency, phonemic awareness, instructional–level reading with an emphasis on comprehension, word analysis, and spelling. This intervention was effective in improving the reading skills of low SES, second–grade English monolingual and English–language learners. 相似文献

The mistakes made when attempting tasks often prove to be some of the most invaluable learning experiences. Despite this, outcome and results driven assessment formats largely penalise student performance errors or reward students who succeed by chance. The consequences of this paradigm are visible effects on student relationships with assessment. The student–tutor consensus approach to assessment was introduced to capture student learning achieved ‘from’ assessment to complement the measurement of performance outcomes. This approach parallels student and tutor judgement in a grade negotiation, affording the student an opportunity to share with their assessor what they have learned from the assessment activity. This student self-awareness was then considered alongside the conventional outcome-based score awarded by the tutor to generate a final grade for the assessed activity. Our study evaluated the perceptions of 90 undergraduate students enrolled in the bachelor of paramedic studies, who participated in this novel assessment approach as part of a final-year capstone topic. The results comprehensively indicated value for all aspects of the assessment approach, as well as a recognition that the skills will be useful in their future professional roles. 相似文献
