Single maximal versus combination punch kinematics     

Piorkowski BA  Lees A  Barton GJ 《Sports biomechanics / International Society of Biomechanics in Sports》2011,10(1):1-11

The aim of this study was to determine the influence of punch type (Jab, Cross, Lead Hook and Reverse Hook) and punch modality (Single maximal, 'In-synch' and 'Out of synch' combination) on punch speed and delivery time. Ten competition-standard volunteers performed punches with markers placed on their anatomical landmarks for 3D motion capture with an eight-camera optoelectronic system. Speed and duration between key moments were computed. There were significant differences in contact speed between punch types (F(2,18,84.87) = 105.76, p = 0.001) with Lead and Reverse Hooks developing greater speed than Jab and Cross. There were significant differences in contact speed between punch modalities (F(2,64,102.87) = 23.52, p = 0.001) with the Single maximal (M+/- SD: 9.26 +/- 2.09 m/s) higher than 'Out of synch' (7.49 +/- 2.32 m/s), 'In-synch' left (8.01 +/- 2.35 m/s) or right lead (7.97 +/- 2.53 m/s). Delivery times were significantly lower for Jab and Cross than Hook. Times were significantly lower 'In-synch' than a Single maximal or 'Out of synch' combination mode. It is concluded that a defender may have more evasion-time than previously reported. This research could be of use to performers and coaches when considering training preparations.  相似文献   

The effect of a supported exercise programme in patients with newly diagnosed Type 2 diabetes: a pilot study     

Backx K  McCann A  Wasley D  Dunseath G  Luzio S  Owens D 《Journal of sports sciences》2011,29(6):579-586

The aim of this study was to examine the effectiveness of either a standard care programme (n = 9) or a 12-week supported exercise programme (n = 10) on glycaemic control, β-cell responsiveness, insulin resistance, and lipid profiles in newly diagnosed Type 2 diabetes patients. The standard care programme consisted of advice to exercise at moderate to high intensity for 30 min five times a week; the supported exercise programme consisted of three 60-min supported plus two unsupported exercise sessions per week. Between-group analyses demonstrated a difference for changes in low-density lipoprotein cholesterol only (standard care programme 0.01 mmol · L(-1), supported exercise programme -0.6 mmol · L(-1); P = 0.04). Following the standard care programme, within-group analyses demonstrated a significant reduction in waist circumference, whereas following the supported exercise programme there were reductions in glycosylated haemoglobin (6.4 vs. 6.0%; P = 0.007), waist circumference (101.4 vs. 97.2 cm; P = 0.021), body mass (91.7 vs. 87.9 kg; P = 0.007), body mass index (30.0 vs. 28.7 kg · m(-2); P = 0.006), total cholesterol (5.3 vs. 4.6 mmol · L(-1); P = 0.046), low-density lipoprotein cholesterol (3.2 vs. 2.6 mmol · L(-1); P = 0.028), fasting β-cell responsiveness (11.5 × 10(-9) vs. 7.0 × 10(-9) pmol · kg(-1) · min(-1); P = 0.009), and insulin resistance (3.0 vs. 2.1; P = 0.049). The supported exercise programme improved glycaemic control through enhanced β-cell function associated with decreased insulin resistance and improved lipid profile. This research highlights the need for research into unsupported and supported exercise programmes to establish more comprehensive lifestyle advice for Type 2 diabetes patients.  相似文献   

Public libraries as reserves of cultural and digital capital: Addressing inequality through digitalization     

Adrian Leguina  Sabina Mihelj  John Downey 《Library & information science research》2021,43(3):101103

Public libraries are among key sites for the acquisition of cultural capital, and possibly one of the most potent means through which the state can address inequality. While digitalization of public libraries already attracted significant scholarly attention, the evidence of its contribution to the acquisition of cultural skills and knowledge and social mobility remains limited, as does the conceptual understanding of links between digitalization, cultural capital, and social stratification. This article draws on two disconnected bodies of research, the sociological analysis of cultural capital and stratification and research on digital divides. To bridge these two bodies of research, the interplay of cultural and digital capital in public libraries was investigated. The extensive dataset from the UK Taking Part Survey (2016–17) was analyzed using two-step cluster analysis and multinomial regression models to explore the contrasting profiles of contemporary library users. Results identify four distinct user groups: Traditional, Active, Family, and Tech Access, which possess different degrees of cultural and digital capital, have different demographic profiles, and benefit from digitalized libraries in different ways. If libraries are to fulfil their role in reducing social inequalities, it is important that they tailor their digital services to the specific characteristics of each user group. This approach also provides a useful template for exploring the interplay of digitalization and (in)equality in other cultural institutions.  相似文献   

Teaching and Transforming Through Stories: An Exploration of Macro- and Micro-Narratives as Teaching Tools     

Jaclyn R. Devine  Todd Quinn 《The Reference Librarian》2014,55(4):273-288

Narratives are one of the most powerful teaching tools available and are often regarded as central to the learning process. We investigate the role of narrative in adult learning in library instructional contexts, introducing the concepts of micro- and macro-narratives and illustrating these ideas using relevant teaching examples. Macro-narratives are stories that are common across many cultures and contain universal themes and lessons. Micro-narratives are stories that are uniquely relevant to the members of a particular group. We argue that both types can be used to create meaningful library learning experiences.  相似文献

Selling abroad: Are we doing enough?     

Adrian Higham 《Publishing Research Quarterly》1988,4(4):45-51

Despite the dominance of the English language, publishers in the United States had export sales in 1987 of less than 6 percent of their total sales. Adrian Higham analyzes the major overseas markets for U.S. books and suggests ways for publishers to improve their export sales to each. The key to higher sales, he argues, is acquiring “insider status” in each market. Although he is convinced that publishers can do better, he reminds us that there is no simple solution. Adrian Higham brings to his consultancy an extensive background in international publishing. Following his wide career with Longman he served as managing director of John Wiley & Sons’ Company in the United Kingdom and subsequently as senior vice president and general manager of the International Group of John Wiley & Sons in New York.  相似文献
