The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions. 相似文献

In this study a method for determining elbow extension and elbow abduction for a cricket bowling delivery was developed and assessed for Jenny Gunn who has hypermobility in both elbows and whose bowling action has been repeatedly queried by umpires. Bowling is a dynamic activity which is assessed visually in real time in a cricket match by an umpire. When the legality of a bowler's action is questioned by an umpire a quantitative analysis is undertaken using a marker based motion analysis system. This method of quantifying elbow extension should agree with a visual assessment of when the arm is "straight" and should minimise the effects of marker movement. A set of six markers on the bowling arm were used to calculate elbow angles. Differences of up to 1° for elbow extension and up to 2° for elbow abduction were found when angles calculated from the marker set for static straight arm trials were compared with measurements taken by a chartered sports physiotherapist. In addition comparison of elbow extension angles at ball release calculated from the markers during bowling trials with those measured from high speed video also showed good agreement with mean differences of 0°±2°. 相似文献

OBJECTIVE: The goal of this study was to examine the association between sexual abuse (SA) and initiation, cessation, and current cigarette smoking among a large representative adult population in France. METHOD: A random sample size of 12,256 adults (18-75 years of age) was interviewed by telephone concerning demographic variables, health practices and beliefs, and health status--for which SA and tobacco questions were included. Bivariate and multivariate analyses were conducted. RESULTS: Nearly 46% of SA survivors were current smokers compared to 34% of non-abused persons (p<.001). Survivors of SA consumed more cigarettes per day than non-abused individuals (14.5 vs. 12.4, p<.01). Survival analysis showed an increased risk of smoking initiation for respondents abused before 18 (adjusted relative hazard=1.55; p<.0001) with referent to the non-abused group. SA was not found to be a significant predictor of current smoking status among those who began smoking after the first incident of SA. Respondents who were not sexually abused were 1.8 times (95% CI, 1.12-2.99) more likely to quit smoking than people who began smoking after they were sexually abused. CONCLUSIONS: The early identification and treatment of sexually abused persons is critical to decrease smoking among adolescents and adults because of the association of SA with both smoking initiation and decreased cessation rates. It may be more difficult to detect an association between SA and current smoking due to the high rates of smoking and lower rates of quitting among the general French population. 相似文献

Product-based analysis (PBA) is a new way of modelling the strategic direction of an educational development centre (EDC). It was developed within an English EDC to complement other strategic techniques, providing a means of visualizing the overall strategy. This critique of PBA is set in the context of global university reforms, restructurings and economic constraints that EDCs mirror in miniature. The case for PBA is demonstrated through two exemplars, one retrospective, the other applied to the same group, now dispersed several years on, as it sets out a collaborative strategy to address the future uncertainties shared by many EDCs. 相似文献

Social justice education within the community college setting has not been an academic focus to date; yet, community colleges remain an environment for a diverse student population due to their low cost, open access, and variety of course delivery methods. Rural community colleges, however, may pose an interesting challenge to those wishing to implement social justice initiatives within coursework and existing programs. This article provides an example of a social justice training program that was developed for resident assistants on a midsized, rural community college in the Midwest, with a booming residential student population, and the challenges encountered during the phases of the project. Results of pre- and postassessments with the participants of the training suggest that a quality training program can equip students with the tools needed to feel more confident in their abilities to perform their job well. 相似文献

The research studies how outstanding teachers from Hong Kong conceptualize teacher success or effectiveness. This study adds to the knowledge base concerned by raising the importance of the coexistence of personal attributes and professional qualities as well as contextual factors, in bringing out the success of a teacher. It draws the attention of teacher educators/trainers and school administrators to the necessity of viewing the concept of teacher success from a broader perspective, instead of focusing narrowly on the professional qualities of a teacher. It also provides insights for school administrators in selecting teachers or supporting their work. 相似文献
