单纤维对训练的适应     

FRANCAUX Marc　MALISOUX Laurent　THEISEN Daniel 《首都体育学院学报》2007,19(6):1-9

随着特殊的训练计划被教练员们采用以促进运动员的肌肉适应能力,肌肉训练也成为渐进式康复的重要组成部分,它能阻止与丧失运动能力、老化、疾病或微重力相关的萎缩效应。为了优化不同类型的干扰措施,需要更好地理解运动训练产生的反应,以及识别决定肌肉功能的各种机制。虽然整体肌肉活动在某种程度上是通过适应运动神经元爆发、运动单元补充模式或者肌肉量来进行的,本研究着重探讨肌肉纤维类型的表达以及训练后收缩肌的功能性适应能力。单一无皮纤维被证明是常用的实验模型,用于研究与肌浆球蛋白重链对碘氧基苯甲醚相关的试管内收缩特性。人体纤维主要的功能和生化特性在过去二十年中已经被详细研究了,但近来,无皮纤维模式正被用于研究不同类型的诱发训练后单纤维的功能适应性。本文的目的是概述收缩肌对于特定运动训练计划的反应,以及帮助形成适用于运动科学和康复的训练计划。  相似文献   

Arousal and cognition: The stimulation-seeking motive and structural effects in the comprehension of film     

Marc T. Braverman  Frank H. Farley 《Educational technology research and development : ETR & D》1978,26(4):321-327

The authors present a study of comprehension as a function of the stimulation-seeking motive in relation to the degree of structure involved in information presented in film. While no significant effects were obtained in measuring comprehension of verbal and pictorial stimuli and literal and inferential processing, the stimulation-seeking motive may have had a moderating effect on the relationship among memory or information-processing systems. This would indicate possible differential-encoding or information-processing strategies between individuals high and low in the stimulation-seeking motive.  相似文献   

Game location and aggression in rugby league     

Jones MV  Bray SR  Olivier S 《Journal of sports sciences》2005,23(4):387-393

The present study examined the relationship between aggression and game location in rugby league. We videotaped a random sample of 21 professional rugby league games played in the 2000 Super League season. Trained observers recorded the frequency of aggressive behaviours. Consistent with previous research, which used territoriality theories as a basis for prediction, we hypothesized that the home team would behave more aggressively than the away team. The results showed no significant difference in the frequency of aggressive behaviours exhibited by the home and away teams. However, the away teams engaged in substantially more aggressive behaviours in games they lost compared with games they won. No significant differences in the pattern of aggressive behaviours for home and away teams emerged as a function of game time (i.e. first or second half) or game situation (i.e. when teams were winning, losing or drawing). The findings suggest that while home and away teams do not display different levels of aggression, the cost of behaving aggressively (in terms of game outcome) may be greater for the away team.  相似文献   

Mixed-method pre-cooling reduces physiological demand without improving performance of medium-fast bowling in the heat     

Minett GM  Duffield R  Kellett A  Portus M 《Journal of sports sciences》2012,30(9):907-915

This study examined physiological and performance effects of pre-cooling on medium-fast bowling in the heat. Ten, medium-fast bowlers completed two randomised trials involving either cooling (mixed-methods) or control (no cooling) interventions before a 6-over bowling spell in 31.9±2.1°C and 63.5±9.3% relative humidity. Measures included bowling performance (ball speed, accuracy and run-up speeds), physical characteristics (global positioning system monitoring and counter-movement jump height), physiological (heart rate, core temperature, skin temperature and sweat loss), biochemical (serum concentrations of damage, stress and inflammation) and perceptual variables (perceived exertion and thermal sensation). Mean ball speed (114.5±7.1 vs. 114.1±7.2 km · h(-1); P = 0.63; d = 0.09), accuracy (43.1±10.6 vs. 44.2±12.5 AU; P = 0.76; d = 0.14) and total run-up speed (19.1±4.1 vs. 19.3±3.8 km · h(-1); P = 0.66; d = 0.06) did not differ between pre-cooling and control respectively; however 20-m sprint speed between overs was 5.9±7.3% greater at Over 4 after pre-cooling (P = 0.03; d = 0.75). Pre-cooling reduced skin temperature after the intervention period (P = 0.006; d = 2.28), core temperature and pre-over heart rates throughout (P = 0.01-0.04; d = 0.96-1.74) and sweat loss by 0.4±0.3 kg (P = 0.01; d = 0.34). Mean rating of perceived exertion and thermal sensation were lower during pre-cooling trials (P = 0.004-0.03; d = 0.77-3.13). Despite no observed improvement in bowling performance, pre-cooling maintained between-over sprint speeds and blunted physiological and perceptual demands to ease the thermoregulatory demands of medium-fast bowling in hot conditions.  相似文献   

A hybrid approach to managing job offers and candidates     

Rémy Kessler  Nicolas Béchet  Mathieu Roche  Juan-Manuel Torres-Moreno  Marc El-Bèze 《Information processing & management》2012

The evolution of the job market has resulted in traditional methods of recruitment becoming insufficient. As it is now necessary to handle volumes of information (mostly in the form of free text) that are impossible to process manually, an analysis and assisted categorization are essential to address this issue. In this paper, we present a combination of the E-Gen and Cortex systems. E-Gen aims to perform analysis and categorization of job offers together with the responses given by the candidates. E-Gen system strategy is based on vectorial and probabilistic models to solve the problem of profiling applications according to a specific job offer. Cortex is a statistical automatic summarization system. In this work, E-Gen uses Cortex as a powerful filter to eliminate irrelevant information contained in candidate answers. Our main objective is to develop a system to assist a recruitment consultant and the results obtained by the proposed combination surpass those of E-Gen in standalone mode on this task.  相似文献   

ARE NON‐OBSERVANT ISRAELI JEWS HEBREW SPEAKING “GOYIM”? Constructivist Cultural Perspectives     

Zvi Bekerman  Marc Silverman 《Journal of Jewish Education》2013,79(1-2):41-49

In order to continue being an authentic Jew, the secular Israeli Jew must be knowledgeable of the Jewish religious heritage. If he is an ignoramus regarding Jewish sources, unattuned to their substance, he approaches the condition of being an Hebrew speaking Goy (Hertzberg, 1995; 7).  相似文献   

Public Opinion of Genetic and Neuropsychological Contributors to Criminal Involvement     

Jamie M. Gajos  Kevin M. Beaver  Marc Gertz  Jake Bratton 《Journal of Criminal Justice Education》2013,24(3):368-385

There is a lack of research that has examined public opinion on the importance of biosocial influences for understanding the potential causes of criminal and delinquent involvement. We address this gap in the current study by surveying a nationally representative sample of adults about the importance of biosocial factors for influencing criminal behavior. Results indicate that the public believes the environment matters more than genetic factors for determining whether someone becomes a criminal. However, the data also reveal an overall acceptance of the importance of neuropsychological factors for influencing criminal behavior. An ordered logistic regression analysis was also estimated to examine potential differences in opinion across demographic categories. The results revealed that income, gender, marital status, and employment status are significantly associated with whether a respondent supports the role of biosocial factors in crime causation. Implications of the findings are discussed.  相似文献
