Abstract This study investigated the effects of goal setting in teacher-led group conferences on achievement in archery. University undergraduates enrolled in three beginning archery classes (N = 30) were randomly assigned to two treatment groups—group conference with goal setting and group conferences only. For 10 weeks, subjects met twice a week for archery instruction and once a week with the instructor for a 10-minute conference. Subjects in the goal-setting conference group were directed to set numerical and verbal goals using a printed goal-setting form. Three achievement tests were administered while subjects were shooting from a distance of 20 yards: an initial test during week 1, a progress test during week 6, and a final test during week 10. Analysis of the data indicated that when groups were adjusted for initial differences, the goal-setting group achieved significantly higher scores in archery than the non-goal-setting group (F = 5.31, p < .05). Motivational implications of goal setting proce...
摘要本研究探讨教师主导小组会议目标设定对射箭成绩的影响。入选3个射箭入门班的大学本科生(N = 30)被随机分为两个治疗组——有目标设定的小组会议组和只有小组会议组。在10周的时间里,受试者每周见两次射箭指导,每周见一次与教练进行10分钟的会议。目标设定会议组的受试者被要求使用一份印刷的目标设定表格来设定数字和口头目标。在受试者进行20码射击时进行三次成绩测试:第1周进行初步测试,第6周进行进度测试,第10周进行最终测试。数据分析表明,调整各组初始差异后,目标设定组射箭成绩显著高于非目标设定组(F = 5.31, p < 0.05)。目标设定过程的动机含义……

Strategies for the analysis of repeated and multiple measures designs. 重复和多重措施设计的分析策略。

Abstract Differentiation is made relative to repeated and multiple measure analyses. A flowchart is provided to help the researcher determine the appropriate analysis for the design of interest. Conservative tests and a multivariate approach are suggested for repeated measures designs. For designs with multiple dependent measures, the following suggestions are provided: rank reduction, Bonferroni approach, and MANOVA. Post hoc tests are also suggested once a significant multivariate F is obtained. The post hoc tests are univariate F tests, two-group breakdown, simultaneous confidence intervals, discriminant analysis, step-down analysis, and contrasts on the classification variable. It is suggested that inclusion of these more appropriate analyses will increase the internal validity of research published in the Research Quarterly.
摘要对重复和多重测量分析进行了区分。提供了一个流程图,以帮助研究人员确定适当的分析感兴趣的设计。对于重复测量设计,建议采用保守试验和多变量方法。对于具有多个相关测量的设计,提供以下建议:秩降,Bonferroni方法和方差分析。一旦获得显著的多变量F,也建议进行事后检验。事后检验是单变量F检验、两组分解、同时置信区间、判别分析、降压分析和分类变量的对比。有人建议,纳入这些更适当的分析将增加研究发表在研究季刊的内部有效性。

Attitudes of volunteer coaches toward significant youth sport issues. 志愿者教练对重大青少年体育问题的态度。
Pub Date : 1979-10-01 DOI: 10.1080/00345377.1979.10615623

Abstract A questionnaire consisting of 20 positive and negative statements frequently made about youth sports was completed by 423 nonschool youth sport coaches from Illinois and Missouri. The coaches indicated to what degree they agreed with the statements for the sport in general, and for the particular program in which they coached. Coaches from eight sports were sampled: baseball/softball, basketball, football, gymnastics, hockey, soccer, swimming, and wrestling. The results revealed that coaches have generally favorable attitudes toward youth sports, supporting the value of participation for the well-being of children. One exception to the coaches' generally favorable attitudes was their moderate agreement that too much emphasis is placed on winning. It also was found that the coaches' 20 specific agreement ratings could be reduced to 4 interpretable factors—“positive attitudes,” “negative facets of youth sports programs,” “negative consequences for participants,” and “equipment and facilities not ad...
摘要以美国伊利诺伊州和密苏里州的423名非学校青少年体育教练员为调查对象,采用问卷调查法,对青少年体育活动中常见的20个正面和负面表述进行问卷调查。教练们表明了他们在多大程度上同意这项运动的总体陈述,以及他们所执教的特定项目。来自棒球/垒球、篮球、足球、体操、曲棍球、足球、游泳和摔跤等八项运动的教练被抽样调查。结果显示,教练员对青少年体育普遍持赞成态度,支持参与对儿童福祉的价值。教练们普遍持有利态度的一个例外是,他们温和地认为过于强调胜利。研究还发现,教练员的20个具体同意等级可以被简化为4个可解释的因素-“积极的态度”,“青少年体育项目的消极方面”,“对参与者的负面影响”和“设备和设施不…

Abstract The purpose of this study was to describe substrate changes in blood and muscles during submaximal exercise and to look at the relationship of these changes to some enzyme activities important in lipid and carbohydrate metabolism. A group of six trained and six untrained men were exercised for 1 hour at 50% [Vdot]O2 max; three from each group cycled and the rest ran on a treadmill. During the exercise, blood-free fatty acid (FFA) levels increased twofold, glycerol by 3.6 times, triglyceride (TG) by 11/100 ml, and glucose by a mean 11 mg/100 ml in the trained men. In the untrained subjects, however, FFA increased 1.8 fold, glycerols 1.6 fold, and TG by a mean 24/100 ml. Glucose fell in every subject by an average 5 mg%. Muscle glycogen depletion averaged 34 mmoles/kg in the untrained and 23 mmoles/kg in the trained group. The activities of succinic acid dehydrogenase (SDH), malic acid dehydrogenase (MDH), and carnitine palmityl transferase (CPT) were greater by 177%, 93%, and 64%, respectively, in...
摘要:本研究的目的是描述亚极限运动时血液和肌肉中的底物变化,并研究这些变化与脂质和碳水化合物代谢中重要的一些酶活性的关系。一组6名训练有素的男子和6名未训练的男子在50% [Vdot]最大氧气下运动1小时;每组三个人骑自行车,其余的人在跑步机上跑步。在训练过程中,血液游离脂肪酸(FFA)水平增加了两倍,甘油增加了3.6倍,甘油三酯(TG)增加了11/100毫升,葡萄糖平均增加了11毫克/100毫升。然而,在未经训练的受试者中,FFA增加了1.8倍,甘油增加了1.6倍,TG平均增加了24/100毫升。葡萄糖平均下降了5毫克%。肌糖原消耗在未训练组平均为34毫摩尔/公斤,训练组为23毫摩尔/公斤。琥珀酸脱氢酶(SDH)、苹果酸脱氢酶(MDH)和肉毒碱棕榈酰转移酶(CPT)活性分别比对照高177%、93%和64%。

High school value climate as related to preferential treatment of athletes. 高中重视气候与运动员的优先待遇有关。

Abstract This paper focuses on the importance of the high school value climate as a mediating variable in the analysis of behavior associated with sport participation. The findings suggest that athletes are accorded preferential treatment in those schools where sport is an important prestige-granting activity. In addition, the findings showed that the athletes were somewhat more conventional than the nonathletes; however, this conventionality was not associated with the school value climate.
摘要本文主要研究高中价值观气候作为中介变量在体育参与行为分析中的重要性。研究结果表明,在那些体育是一项重要的声望授予活动的学校,运动员得到了优待。此外,研究结果显示,运动员比非运动员在某种程度上更传统;然而,这种传统与学校的价值氛围无关。
