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

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

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

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

During its first decade, About Campus published the “What They're Reading” department highlighting publications related to the support of student learning. While that department officially signed off several years ago, Jennifer L. Bloom and Marc Lowenstein offer two lists of publications valuable to their work helping college students learn and succeed. 相似文献

Japanese and South American immigrant mothers' parenting cognitions (attributions and self-perceptions) were compared with mothers from their country of origin (Japan and Argentina, respectively) and European American mothers in the United States. Participants were 231 mothers of 20-month-old children. Generally, South American immigrant mothers' parenting cognitions more closely resembled those of mothers in the United States, whereas Japanese immigrant mothers' cognitions tended to be similar to those of Japanese mothers or intermediate between Japanese and U.S. mothers. This study provides insight into the nature of parenting cognitions generally and those of immigrant mothers specifically and therefore the parenting climate in which immigrant children are reared. 相似文献

This paper shows how concept mapping can be used to measure the quality of e‐learning. Six volunteers (all of them 3rd‐year medical students) took part in a programme of e‐learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping. The quality of change in individuals' maps was assessed using criteria developed to distinguish between meaningful and rote‐learning outcomes. Student maps were also scored for evidence of conceptual richness and understanding. Finally, each map was compared directly with the content of the electronic teaching material. The results show that many of the student misconceptions were put right in the course of their learning but that many of the key concepts introduced in the teaching were ignored (or sometimes learnt by rote) by the students. This was because the teaching material locked these new ideas in structures and terminology that precluded meaning‐making among non‐experts. Our data suggest that students' prior knowledge is a key determinant of meaningful learning. We suggest that this must be acknowledged if the design and use of electronic teaching material is also to be meaningful. Ultimately, measures of student learning are the only authentic indicators of the quality of teaching through technology. 相似文献

This special issue presents an outstanding overview of theoretical models of multiple text comprehension. The goal of this commentary is to synthesize insights from the four models and identify recurring themes. In so doing, I outline skills needed by the proficient reader emphasizing the importance of adaptivity. I conclude with an outlook on potentials of and barriers to promoting the skills of multiple document comprehension in a sustainable way. 相似文献
