Purpose: Decline of motor performance in older individuals affects their quality of life. Understanding the contribution of sport-related training in advanced ages might help to attenuate motor performance decay as one gets older. The purpose of our study was to evaluate the extent to which long-lasting training in running or sport-specific skills during old age preserves motor performance in different motor tasks. Method: Older runners and tennis players with at least 10 years of training were assessed as were age-matched and young exercisers. Performance was evaluated for 6 motor tasks requiring different functions of sensorimotor control expected to decline with aging. Results: Analysis revealed that runners had increased aerobic fitness in comparison with the other older participants and that they presented similar performance to older exercisers in the motor tasks. Tennis players outperformed the other groups of older participants on coincident timing and simple reaction time and achieved similar performance to the young group on the timing task. Conclusions: These results suggest selective maintenance of task-specific processing through extensive practice of tennis-related motor skills in older adults.  相似文献   

The Effects of a Group Contingency Strategy on Behaviorally Disordered Students in Physical Education     

E. William Vogler  Ron W. French 《Research quarterly for exercise and sport》2013,84(3):273-277

Abstract

An A-B-A-B time-series design was used to determine the effectiveness of a group contingency strategy in modifying on-task behavior of behaviorally disordered students in a physical education setting. A younger group (n = 12) with a mean age of 7.8 years, and an older group (n = 11) with a mean age of 11.2 years, participated in a study in which activity reinforcement for each group was contingent upon correct observation of the rules established for class. The group contingency strategy was significantly effective in increasing the percentage of on-task behavior of both groups of students. In addition, there was no significant difference in the response to treatment between younger and older students, and there were no individuals within either group who did not respond favorably to treatment.  相似文献   

The Differential Effect of Indirect Instruction in the Teaching of Sport Skills on Critical Thinking and Self-esteem of Early Adolescent Boys Placed at Risk     

Randy Bonnette  Ron E. McBride  Homer Tolson 《Sport, Education and Society》2013,18(2):183-198

The purpose of this study was to examine the differential effect of sport skills instruction (SSI) and sport skills instruction plus initiative games (SSI +) on the critical thinking (CT) and self-esteem scores of early adolescent boys placed at risk. Students in the SSI + group ( n = 36) participated in initiative games classes in addition to their sport skills activities. Students in the SSI group (n = 44) participated in the sport skills activities only. Since the boys were divided by age (10-11 & 12-13), the influence of age on the dependent variables was also investigated. Classes taught by the initiative games teacher were student-centered while the sport skills classes were teacher-centered. Significant differences between teacher behaviors occurred in interaction patterns, instructional strategies, and management concerns. There were no differences on self-esteem scores. The results supported the addition of initiative games to SSI to foster CT with this group of participants.  相似文献   

LEARNING ABOUT TEACHING THE EXTRACURRICULAR TOPIC OF NANOTECHNOLOGY AS A VEHICLE FOR ACHIEVING A SUSTAINABLE CHANGE IN SCIENCE EDUCATION     

Ron Blonder  Rachel Mamlok-Naaman 《International Journal of Science and Mathematics Education》2016,14(3):345-372

This study focused on teachers’ transfer of a variety of teaching methods from a teaching module on nanotechnology, which is an example of a topic outside the science curriculum, to teaching topics that are part of the chemistry curriculum. Nanotechnology is outside the science curriculum, but it was used in this study as a means to carry out a change in the way chemistry teachers teach. The participants in the study included nine high school in-service chemistry teachers. Three research tools were used: (1) semistructured interviews that were conducted with the teachers, after they had finished teaching their nanotechnology module, and follow-up semistructured interviews that were conducted 2 years after the teachers had taught the nanotechnology module , and teachers’ assessment and evaluation of their own teaching method, determining how the nanotechnology modules influenced the students who learned according to this program. The data collection process continued for 5 years. Most of the teachers indicated that they continued teaching the nanotechnology module that they designed and all of them stated that they integrated the unique teaching methods into their teaching of chemistry. High efficacy beliefs were built based on the self-evaluation process that was part of the teachers’ professional development program. Teaching self-efficacy beliefs and organization efficacy beliefs was found to contribute to teachers’ sustainable changes. The findings in the current research are only limited to the topic of nanotechnology; however, we believe that similar results can be obtained for any modern scientific topic that is outside the high school science curriculum. We suggest that more research should be done to determine whether the same findings emerge by using the same approach but on another topic.  相似文献

Talking Smack: Verbal Aggression in Professional Wrestling     

Ron Tamborini  Ken Lachlan  David Westerman  Paul Skalski 《Communication Studies》2013,64(3):242-258

The current study presents the results of a content analysis of the verbal aggression found in 36 hours of televised professional wrestling. The coding scheme was adapted from the National Television Violence Study and past research on television verbal aggression. Results show that an abundance of verbal aggression occurs in televised professional wrestling, with swearing, competence attacks, and character attacks being the most common types. In addition, the primary motives for verbal aggression use are amusement and anger. Furthermore, verbal aggression tends to be communicated and received by White, male individuals with no clear dispositional characteristics. The results are discussed in terms of potential effects of exposure to the verbal aggression found in professional wrestling.  相似文献

Repeated Exposure to Daytime Soap Opera and Shifts in Moral Judgment Toward Social Convention     

Ron Tamborini Ph.D.  René Weber Ph.D.  M.D.  Allison Eden M.A.  Nicholas David Bowman Ph.D.  Matthew Grizzard M.A.  Ph.D. 《广播与电子媒介杂志》2013,57(4):621-640

This study examined the influence of prolonged exposure to soap opera on character dispositions and real-world moral judgments. Eight groups viewed from 0–7 weeks of soap opera prior to a final week after which participants completed measures of disposition towards show characters as well as perceptions of morality in real-world situations. Results demonstrated the effect of prolonged exposure on both the polarization of dispositions toward characters and a trend in moral judgments toward social convention. These findings highlight the role of disposition within social cognitive theory, and the importance of dispositional considerations in understanding learned morality.  相似文献   

The Spiral of Violence: Equity of Violent Reprisal in Professional Wrestling and its Dispositional and Motivational Features     

Kenneth A. Lachlan Ph.D.  Ron Tamborini Ph.D.  Rene Weber Ph.D.  M.D.  David Westerman Ph.D.  Paul Skalski Ph.D.  Jeff Davis M.A. 《广播与电子媒介杂志》2013,57(1):56-75

Though lacking empirical evidence, professional wrestling has been criticized for portraying excessive violence in harmful contexts. This study focused on the equity of violent reprisal perpetrated by liked versus disliked protagonists with socially sanctioned or unsanctioned motives. Results of a quantitative content analysis show that most violent interaction sequences were over-retributive. Violence that was not part of match competition was routinely initiated for normatively unsanctioned motives and showed predominant patterns of escalating violent retribution. These patterns held across perpetrator disposition. Thus, liked characters regularly aggressed for normatively unacceptable reasons. The consequences of these portrayals are discussed.  相似文献
