Spot Reduction of Subcutaneous Adipose Tissue     

Arne L. Olson  Elliott Edelstein 《Research quarterly for exercise and sport》2013,84(3):647-652

Abstract

This study was designed to determine if the skinfold measurements on an exercised arm would decrease as a result of regular weight training with that arm. Thirty-two subjects completed three sets of 7-RM curls and three sets of 7-RM triceps extensions on either a daily or an alternate day schedule for a period of 6 weeks. The nonexercised arm was measured to establish the specificity of the spot reduction on the exercised arm. The results indicate that hard exercise in a specific area of the arm will result in a reduction of the subcutaneous adipose tissue in that area.  相似文献   

Lumbo-pelvic loading during fast bowling in adolescent cricketers: The influence of bowling speed and technique     

Helen Crewe  Amity Campbell  Bruce Elliott 《Journal of sports sciences》2013,31(10):1082-1090

Abstract

This study aimed to assess changes in bowling technique and lumbar load over the course of a bowling spell in adolescent fast bowlers, and to investigate the relationship between lumbar loads during fast bowling and kinematic factors which have previously been associated with low back injury. Three-dimensional motion analysis was carried out on forty participants who performed an 8-over bowling spell. There were no significant changes in bowling technique or lumbar loads over the course of the spell. Bowling with a more extended front knee, faster ball release speed and increased shoulder counter-rotation were related to increased lumbo-pelvic loading – in particular peak transverse plane rotation moments and anterior-posterior shear forces. These lumbar loads may be a factor in low back injury aetiology and future studies should investigate the relationship between lumbar loading, injury incidence and other risk factors.  相似文献   

Laboratory versus field testing in cricket bowling: A review of current and past practice in modelling techniques     

Bruce Elliott  Jacqueline Alderson 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(1):99-108

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.  相似文献   

Tennis     

Machar Reid  Bruce Elliott 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(1):47-68

The study investigated differences in the one‐ (SH) and two‐handed (DH) backhands when hit flat, across‐court (AC) and down‐the‐line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college‐level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high‐speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1°; DH: 83.4°) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m; DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m; DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s; DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique.  相似文献   

Diversification around Europe – performance measuring with regard to different missions     

Roessler  Isabel  Catacutan  Katrina 《Tertiary Education and Management》2020,26(3):265-279

Existing university ranking systems blur differences between Higher Education Institutions because they only focus on research. The increased breadth, diversity and complexity of Higher Education Institutions’ missions are repeatedly overlooked causing a low visibility to a wide audience. This paper demonstrates the possibilities to measure other missions such as international orientation and regional engagement. Therefore, the results of 618 Higher Education Institutions (Effective March 2016) in U-Multirank, an international university ranking, are used. The results show the impressive variety in the higher education systems among European regions. Every region found missions in which they effectively perform thus proving the importance of each mission. The multidimensional ranking takes into account the complexity of Higher Education Institutions’ missions and capturing the relevance of Higher Education Institutions third mission’s activities adequately. Transparency across all missions is the only possibility to make the performances honourable. As research is not the only remarkable mission of Higher Education Institutions, teaching is not the only necessary mission. When other missions are overlooked, the performance measurement systems hinder mission diversity in higher education.

The impact of fostering relationships through music within a special school classroom for students with autism spectrum disorder: an action research study     

Katrina Skewes McFerran  Grace Thompson  Lucy Bolger 《Educational Action Research》2016,24(2):241-259

Music therapists have been working in special education contexts for many decades, utilising research and case studies to inform practice. Growing interest in the link between the creative arts and well-being has led music therapists to consider what aspects of their knowledge others could feasibly appropriate in the school system. An action research approach was utilised to explore this question, grounded in partnerships between university-based music therapy researchers and staff at a school for learners on the autistic spectrum. Five cycles of planning, action, observation and reflection framed the collaborative partnership, with a music therapist acting as consultant to explore how music could be used across the school day. The greatest shift evidenced through qualitative and quantitative analysis was in the area of relationship building. Rather than seeing music as a tool that supports the acquisition of specific skills, the professionals and students in the school came to understand that music could be a meaningful part of their encounter with one another. This is congruent with music therapy research findings that also emphasise the ways music can be used to motivate, evoke and elicit meaningful responses from young people. Some limitations were identified in the sustainability of music practices in the school, particularly when other parts of the school culture were changing.  相似文献
