Histograms of push-ups and curl-ups from a sample of more than 9,000 students show periodic spikes at five and 10 unit intervals. This article argues that these spikes are related to focal points, a game theoretic concept popularized by Nobel Laureate Thomas Schelling. Being focal on one test makes one more likely to be focal on the other. Focal students (whose push-up score is a multiple of 5 and whose curl-up score is a multiple of 10) behave differently from their non-focal peers. They are more likely athletic, older, and male. Focal students, on average, did 2.2 more push-ups, 1.7 more curl-ups, and ran the mile 15 seconds faster than non-focal students, even controlling for these covariates of performance. By contrast, being focal on a single activity did not produce a statistically significant mile time difference. Students who systematically stop at focal outcomes appear differentially motivated toward physical activity performance. 相似文献

Abstract To better understand the contextual interference effect, in two experiments we investigated a form of practice schedule that provided novices with systematic increases in contextual interference. This new type of practice schedule was compared with traditional blocked and random scheduling for two types of sports skills. In Experiment 1, we tested the hypothesis that practising variations of the same task with systematic increases in contextual interference would lead to superior performance compared with blocked or random scheduling. Participants practised golf putting tasks following a blocked, random or increasing schedule, which involved initial blocked trials, followed by serial practice trials, and ended with random scheduling. Participants who followed the increasing schedule had superior retention test performance. In Experiment 2, we tested if these learning benefits were observed when learning tasks controlled by different generalized motor programs. Participants practised three different basketball passes (chest, overhead, single arm) in a blocked, random or increasing schedule. Participants practising with gradual increases in contextual interference performed better on retention and transfer tests than participants practising with blocked or random scheduling. The results of these two experiments indicate that a practice schedule offering systematic increases in contextual interference facilitates skill learning. 相似文献

Abstract The Sport Orientation Questionnaire (SOQ) was developed as a multidimensional, sport-specific measure of individual differences in sport achievement orientation. Exploratory and confirmatory factor analyses revealed a stable, three-factor structure across three separate samples of university and high school students. The three separate but related subscales of competitiveness, win, and goal orientation demonstrate high internal consistency and stability over time. The SOQ competitiveness score differentiates students in competitive activities from those in noncompetitive activities, providing evidence for construct validity. The overall factor stability, reliability and validity evidence suggests that the SOQ can be a valuable measure for the investigation of competitiveness and achievement behavior in sport and exercise settings. 相似文献

《Sport Management Review》2017,20(4):365-378
The purpose of this study was to analyse the effect that participating in extracurricular sporting activities has on academic performance among students in higher education. Prior research on this topic has yielded contradictory results: while some authors find a positive effect of sports participation on academic outcomes, others report a negative impact. Accordingly, the authors seek to provide a more rounded understanding of these mixed findings. The empirical evidence is provided by a panel dataset of undergraduate students who studied at a Spanish University over the period 2008–2014. The academic performance of sports participants are compared with those of non-participants in terms of their outcomes in the form of grades. Results reveal that participation in formal sporting activities is associated with higher grades among students at this university. The analysis reinforces the idea that apart from their health benefits for practitioners, sporting activities lead to the attainment of the performance goals to which higher education institutions aspire. 相似文献

The purpose of these studies was to examine the relationship between perceptions of exercise-related changes (i.e., perceived mastery and physical change) and certainty with regard to the self-as-exerciser. It was hypothesized that seeing "change" would be associated with more favorable levels of exercise self-certainty and behavior relative to "no change." Online surveys were repeatedly administered across 4 months (Study 1) and 4 weeks (Study 2) to 196 university students (M(age) = 20.17), and 250 community dwellers (M(age) = 38.44), respectively. Data were analyzed via latent variable modeling procedures. Consistent with hypotheses, latent classes (i.e., subgroups) reflecting interindividual differences in levels and trajectories of perceived change were associated with distinct patterns of self-certainty and exercise behavior. The findings suggest that adults who experience mastery of skills and physiological changes also have greater self-certainty and exercise more regularly than those who do not see progress or feel as certain of their exercise identity. 相似文献

Abstract The purpose of this study was to determine: (a) if preperformance behaviors display a consistent rhythm across disparate activities; and (b) the relationship of periodicity for such preperformance routines to successful performance. Seven male volunteers were subjects for this study. Each subject had an established ritual for golf putt, basketball free throw, and tennis serve. Data were collected with a motion-analysis system and video camera while the subjects performed each activity. Dependent measures were types of preperformance behaviors, absolute timing of behaviors, relative timing of behaviors, differences in relative times across activities, and successful performance, and mechanical variables related to performance. Analysis of variance (Subject x Activity) indicated significant main effects and interactions for absolute and relative timing of behaviors. Significant correlations were determined to exist between relative time and success, and differences were found between relative times across activity and successful performance. It was concluded that rituals result from endogenous rhythms and that stable periodicity of behaviors across activities promotes successful performance. 相似文献

高压氧对急性力竭性运动后血乳酸清除和肝酶谱恢复的影响 总被引：9，自引：0，他引：9
为了探讨HBO对力竭性运动后机体乳酸代谢和血清肝细胞酶的影响,让20名体育系男大学生在自行车功率计上运动至力竭,然后随机分成HBO组和对照组,他们分别在HBO和自然状态下恢复约120Min。在运动前、运动后和运动后2小时(恢复期)测定血清乳酸含量和LDB,ALAT、ALP、r-GT活力以及CG的含量。实验结果:力竭性运动后,HBO组和对照组血清LA的含量、LDH、ALAT、ALP、r-GT活力均显著升高,而血清CG含量却显著下降。恢复期,HBO组的LA含量显著低于运动后即刻(P<0.001)和运动前水平(F<0.01),并显著低于对照组(P<0.05)。恢复期与运动后比较,HBO组的血清LDH和r-GT活力均显著下降,而对照组虽有下降,但无显著性差异,虽然HBO组和对照组的ALAT活力均显著下降,但无显著性差异,虽然HBO组和对照组的ALAT活力均显著下降,但HBO组下降幅度比对照组大。实验结果提示:力竭性运动可引起机体肝细胞通透性的增加或损伤,HBO可以促进机体LA的清除和血清肝细胞酶的恢复,有利于运动疲劳的恢复。 相似文献

AbstractIn taekwondo, the stance position can potentially affect kick performance. The aim of this study was to analyse mechanical variables in the roundhouse kick in taekwondo according to three stance positions (0°, 45°, 90°). Nine experienced taekwondo athletes performed consecutive kicking trials in a random order according to these three relative positions of the feet on the ground. Measurements for the mechanical analysis were performed using two 3D force plates and an eight-camera motion capture system. The taekwondo athletes’ reaction and execution times were shorter when starting from the 0° and 45° stance positions than from the 90° position (P < 0.05). Moreover, the ground reaction force was negatively correlated with execution time and positively with velocity of thigh and shank. Our results suggest that the stance position affects the execution technique of taekwondo athletes’ kicks. It is suggested that athletes should not adopt the 90° stance position because it will not enable them to achieve the best performance in the roundhouse kick. 相似文献

The purpose of three related studies was to develop a social dance instrument that had logical validity and generalizable performance ratings. Three social dance experts critiqued the instrument and concluded the items described the characteristics of good social dance performance. Twelve couples from a social dance class were videotaped for 5 min while performing the fox trot. Their performances were evaluated by a different set of coders in each of the three generalizability (G-) studies conducted (Subjects x Coders x Days ANOVA design). Dance performances were held constant across coding occasions so the day facet represents degree of consistency in coding, not stability of subjects' performances. Decision (D-) studies were also conducted for various measurement conditions. Results of the G-studies indicated that coders with several years of experience teaching and evaluating dance had less systematic coder bias and less systematic coder bias for a subset of dancers than coders who had little or no experience evaluating movement of any form. The performance ratings given by novice coders could be generalized for any randomly selected coder evaluating on any given day (G = .79). It was concluded the social dance test was valid and coders could be trained to obtain generalizable performance ratings. 相似文献

以毛荣建（2003）所提出假设（在TPB理论基础上做出改进,将行为习惯、目标态度、情感体验3个变量融入了计划行为理论模型中,用来测量青少年体育锻炼态度。）为研究理论依托,进一步验证体育锻炼态度及其影响因素与体育锻炼行为之间的关系,通过《锻炼态度》与《体育锻炼行为》问卷对在校大学生分层随机调查,运用方差分析、相关分析、回归分析与路径分析等方法分析数据,结果表明：锻炼者与非锻炼者在体育锻炼态度各维度上呈现显著性差异;性别因素不能影响锻炼人群在体育锻炼态度的各项维度得分的差异性的结果,非锻炼人群也是如此;体育锻炼活动中,决定行为意向的关键变量因素是态度;具有高情感体验、或高认知的大学生,并不一定是锻炼者。路径分析说明,行为习惯、情感体验、行为认知、目标态度、主观标准一方面通过行为态度间接作用体育行为,另一方面,行为习惯、目标态度、主观标准对体育行为还具有直接的预测作用。 相似文献
