Currently, it is unclear whether manipulation of movement velocity during resistance exercise has an effect on hypertrophy of specific muscles. The purpose of this systematic review of literature was to investigate the effect of movement velocity during resistance training on muscle hypertrophy. Five electronic databases were searched using terms related to movement velocity and resistance training. Inclusion criteria were randomised and non-randomised comparative studies; published in English; included healthy adults; used dynamic resistance exercise interventions directly comparing fast training to slower movement velocity training; matched in prescribed intensity and volume; duration ≥4 weeks; and measured muscle hypertrophy. A total of six studies were included involving 119 untrained participants. Hypertrophy of the quadriceps was examined in five studies and of the biceps brachii in two studies. Three studies found significantly greater increases in hypertrophy of the quadriceps for moderate-slow compared to fast training. For the remaining studies examining the quadriceps, significant within-group increase in hypertrophy was found for only moderate-slow training in one study and for only fast training in the other study. The two studies that examined hypertrophy of the biceps brachii found greater increases for fast compared to moderate-slow training. Caution is required when interpreting the findings from this review due to the low number of studies, hence insufficient data. Future longitudinal randomised controlled studies in cohorts of healthy adults are required to confirm and extend our findings.  相似文献

Special educational provision in the Republic of Ireland has experienced significant changes in the past decade. A combination of interrelated factors including litigation, legislation, parental advocacy and international developments has radically altered the landscape of special education. As a result of these changes the move towards establishing inclusive learning environments appears irreversible though many critical issues remain to be addressed at this time of transition. This study examines how key stakeholders in primary education perceive the challenge of responding appropriately to increased diversity. The results indicate that many barriers remain in the development of inclusive learning environments. The conceptual understanding of special educational needs (SEN) was seriously deficient and this affected the coherence of policy and service delivery. The system lacked strategic leadership, according to participants, and this restricted the capacity to support schools. School capacity to deliver quality education for children with SEN was constrained by the serious shortfall in the range and level of skills required and opportunities for professional development available. There was strong support for the principle of inclusion into mainstream though this was principally perceived in terms of the development of socialisation skills. It was concluded that in this transition phase schools required strategic leadership from policy‐makers to address the many challenges that remain in the establishment of inclusive learning environments.  相似文献

Basic evaluation research of interim programs conducted to date has employed three of four conceptual models. In the present article, the authors (1) identify these four conceptual models, (2) briefly outline significant studies that have been conducted using three of them, and (3) explore the possible advantages of one model which has not been used or reported in the literature of higher education. It is hoped that some insight into the possible ways to evaluate interim programs was provided, that further thought about objective evaluation programs was initiated, and that creative ventures into areas not yet researched were stimulated.  相似文献

The concept of the transfer of kinetic energy (KE) sequentially through the human body from proximal to distal segments is an influential concept in biomechanics literature. The present study develops this area of research through investigation of segmental sequencing of the transfer of KE by means of computer simulation. Using a musculoskeletal computer model previously developed by the authors, driven using three-dimensional kinematic data from a single elite male golfer, combined inverse and forward dynamics analyses enabled derivation of KE. Rigid body segments of torso, hips, arms and clubhead were examined in line with previous literature. Using this method a driver swing was compared to a 7 iron swing. Findings showed a high level of correlation between driver and iron peak KE and timing of peak KE relative to impact. This seems to indicate equivalent trunk and arms linear velocity, thus force applied, for an iron shot and a driver shot. There were highly significant differences between KE output for body segments for both clubs. In addition, peak KE magnitudes increased sequentially from proximal to distal segments during swing simulations for both the driver and 7 iron. This supports the principle of the summation of speed. However, timing of peak KE was not sequential from proximal to distal segments, nor did segments peak simultaneously. Rather, arms peaked first, followed by hips, torso and club. This seems to indicate a subjective optimal coordination of sequencing.

In 1974 a British biologist, John Randal Baker (1900-1984), published a large and controversial book simply entitled Race that reiterated persistent eugenicist themes concerning the relation between race, intelligence, and progress. The history of Baker's book is a case study in the politics of scientific publishing, and his ideas influenced scholars associated with later works such as The Bell Curve. Baker, a student of Julian Huxley, was a longtime participant in the British eugenics movement and opponent of what he took to be a facile belief in human equality. In 1942, together with Michael Polanyi, he founded the Society for Freedom in Science to oppose those who advocated the central planning of scientific research. Baker's eugenics, political activities, and views on race express an elitist individualism, associated with the conservative wing of the eugenics movement, that this paper explores in the context of his career as a whole.  相似文献

Ego integrity, the last developmental task in Erikson's psychological theory, develops naturally among older people. However, the presence of loss–like physical disability–can considerably affect the quality of life, interactions, and well being of older adults. Hence, older people with physical disabilities need more assistance in accomplishing tasks of ego integrity. This study aimed to utilize traditional Filipino art to capture the essence of the lived experiences of a select group of older people with physical disabilities in relation to their ego integrity. Four Filipino elderly with physical disabilities were purposely selected for this study. Picture prompting and doodling sessions were held as pretest and posttest to ascertain the effectiveness of puni-making in facilitating ego integrity of participants. A series of interviews were pursued to elicit experiences and feelings of participants regarding their disability and old age. From the analysis of the triangulated set of data, two findings emerged. First, four activators of ego integrity, namely: work, family, belief in self and belief in God, were identified as essentials in the formation of the participants' ego-integrity. Second, shifts related to the activators were identified indicating ego integrity's source, meaning and connection elements have become more grounded, certain and integrated. The influence of puni-making in understanding the ego integrity of older people with disabilities was found to be a sound and novel recreational therapy. It can stimulate a select group of Filipino elderly for openness to share their subjective and yet illuminating life experiences.  相似文献

Many existing systems for analyzing and summarizing customer reviews about products or service are based on a number of prominent review aspects. Conventionally, the prominent review aspects of a product type are determined manually. This costly approach cannot scale to large and cross-domain services such as Amazon.com, Taobao.com or Yelp.com where there are a large number of product types and new products emerge almost everyday. In this paper, we propose a novel method empowered by knowledge sources such as Probase and WordNet, for extracting the most prominent aspects of a given product type from textual reviews. The proposed method, ExtRA (Extraction of Prominent Review Aspects), (i) extracts the aspect candidates from text reviews based on a data-driven approach, (ii) builds an aspect graph utilizing the Probase to narrow the aspect space, (iii) separates the space into reasonable aspect clusters by employing a set ofproposed algorithms and finally (iv) generates K most prominent aspect terms or phrases which do not overlap semantically automatically without supervision from those aspect clusters. ExtRA extracts high-quality prominent aspects as well as aspect clusters with little semantic overlap by exploring knowledge sources. ExtRA can extract not only words but also phrases as prominent aspects. Furthermore, it is general-purpose and can be applied to almost any type of product and service. Extensive experiments show that ExtRA is effective and achieves the state-of-the-art performance on a dataset consisting of different product types.  相似文献

In the past decade Ireland has witnessed substantial changes in policy and provision for children with general learning difficulties as government policies and legislation increasingly underpin the move towards more inclusive provision. Despite this series of policy initiatives parents of children who experience Down syndrome and general learning difficulties can encounter serious obstacles in gaining access to mainstream education for their children.
This research project was a study of the experiences of a small sample of parents of children who experience Down syndrome and general learning difficulties in relation to their efforts to access appropriate education and education supports for their child in the mainstream school setting. These parents had to invest extraordinary levels of time, energy, and resources in their struggle to get these children into mainstream school and to support their progress there. At local school level these parents and children had positive experiences, but life has taught them that society offers acceptance as a favour, so they cannot confidently expect acceptance by schools and teachers as a right.  相似文献
