Neuromuscular adaptations to training, injury and passive interventions: implications for running economy

Performance in endurance sports such as running, cycling and triathlon has long been investigated from a physiological perspective. A strong relationship between running economy and distance running performance is well established in the literature. From this established base, improvements in running economy have traditionally been achieved through endurance training. More recently, research has demonstrated short-term resistance and plyometric training has resulted in enhanced running economy. This improvement in running economy has been hypothesized to be a result of enhanced neuromuscular characteristics such as improved muscle power development and more efficient use of stored elastic energy during running. Changes in indirect measures of neuromuscular control (i.e. stance phase contact times, maximal forward jumps) have been used to support this hypothesis. These results suggest that neuromuscular adaptations in response to training (i.e. neuromuscular learning effects) are an important contributor to enhancements in running economy. However, there is no direct evidence to suggest that these adaptations translate into more efficient muscle recruitment patterns during running. Optimization of training and run performance may be facilitated through direct investigation of muscle recruitment patterns before and after training interventions.

There is emerging evidence that demonstrates neuromuscular adaptations during running and cycling vary with training status. Highly trained runners and cyclists display more refined patterns of muscle recruitment than their novice counterparts. In contrast, interference with motor learning and neuromuscular adaptation may occur as a result of ongoing multidiscipline training (e.g. triathlon). In the sport of triathlon, impairments in running economy are frequently observed after cycling. This impairment is related mainly to physiological stress, but an alteration in lower limb muscle coordination during running after cycling has also been observed. Muscle activity during running after cycling has yet to be fully investigated, and to date, the effect of alterations in muscle coordination on running economy is largely unknown. Stretching, which is another mode of training, may induce acute neuromuscular effects but does not appear to alter running economy.

There are also factors other than training structure that may influence running economy and neuromuscular adaptations. For example, passive interventions such as shoes and in-shoe orthoses, as well as the presence of musculoskeletal injury, may be considered important modulators of neuromuscular control and run performance. Alterations in muscle activity and running economy have been reported with different shoes and in-shoe orthoses; however, these changes appear to be subject-specific and nonsystematic. Musculoskeletal injury has been associated with modifications in lower limb neuromuscular control, which may persist well after an athlete has returned to activity. The influence of changes in neuromuscular control as a result of injury on running economy has yet to be examined thoroughly, and should be considered in future experimental design and training analysis.

A global knowledge economy? Biopolitical strategies in India and the European Union

This article critiques the notion of a cross-national convergence of institutional and policy responses to science-based technologies. The continued significance of institutional legacies is demonstrated through a comparative analysis of strategies for the biopharma industry in two radically different settings: India and the European Union (EU). Tensions are evident in both the EU ‘high’ route and the mixed strategy pursued in India. State promotion of biopharma is seen in India as a pathway to economic development, framed by a vision of India as a global power. Here, the ‘low’ route of cost advantages is combined with a ‘global’ rhetoric of innovation, modeled on US experience, and uneven forays into advanced R&D. The pursuit of product innovation was reinforced by India’s adoption of TRIPS-mandated intellectual property rights. In the EU, the aim is an integrated policy and regulatory approach to sustain and legitimize European integration, with the ultimate intent of overtaking the USA.

Case Study from Australia Post : towards the online economy with netPOS

Examines how the "old economy" of the traditional postal service has changed over time and how Australia Post is adapting to the many pressures that threaten its existence. With increasing adoption of e-mail as a means of communication, increased competition as a result of deregulation, and the strain of servicing a country with huge distances between inhabited locations and low population density, Australia Post needed to find a solution that would ensure the long-term viability of its business. The retail sector, with its 4,000-plus post office outlets, processed many different types of across-the-counter financial transactions, including banking transactions and utility payments. A project team was established to address the fundamental issue of how to structure the IT infrastructure to enable retail outlets to generate future revenue flows for Post. However, having established the Internet-based infrastructure to connect the extensive chain of retail outlets, the question was whether this new infrastructure would successfully entice third parties to buy into the model.

Outsourcing the risks : alcohol licensing, risk and the making of the night time economy

Mariana Valverde argues that in the late twentieth century, the British state contracted out the prevention of disorder and monitoring of risks produced by widespread alcohol use to the private sector through the process of liquor licensing. This paper will argue that this scenario was duplicated in Victoria at the same time. It will do so by an analysis of four government-instigated inquiries into liquor licensing regimes from 1965 to 1998. The inquiries were distinguished by the subtly different emphases in their terms of reference. In 1965, the Phillips Royal Commission was directed to inquire into the best ways of dealing with the problems alcohol produced and how best to regulate it for the benefit of the population as a whole. By the time the Nieuwenhuysen Report was commissioned in 1985, the emphasis had changed, and he was directed to inquire how best to serve the interests of alcohol consumers and to produce the licensing regulatory regime which would enable the construction of a 24-hour city. Any anomalies that still existed in the revised Act were eliminated in the 1998 review which was instigated as a direct response to the National Competition Policy. A consequence of these changes over 30 years was the development of particular risk groups, such as ‘binge-drinking young people’, whose violence and nuisance must be controlled to enable all other ‘reasonable’ and ‘moderate’ drinkers be allowed to keep drinking. Thus the notion of risk had been redefined and the responsibility for dealing with these risks had been directed from the state to individual licensees and individual drinkers.

ID scanners in the Australian night-time economy

The recent introduction of ID scanners into the night time economy in many Australian cities is fertile ground for exploring a range of themes related to technology and society. There are questions about the scanners' contribution to increased surveillance, the interface between private and public forms of surveillance, the capacity for data ahsring, concerns about the protection of privacy and the capacity or utility of existing theoretical models dealing with human surveillance, harm prevention, individual freedoms, and the role of technology in promoting social order.

Intellectual property, creativity and innovation : IP models and the political economy of developing Asia

In advanced capitalist societies, intellectual property laws protecting such subject matter as copyright and patents are justified by a combination of theories, which include the provision of economic incentives to foster creativity and innovation and the prevention of unfair competition. IP academics and policy makers have differing views about the appropriate balance between these objectives and public interest considerations such as health, education and the protection of the environment. These different views entered the policy debate in Asian developing countries in connection with an unprecedented introduction and expansion of IP laws over the last 25 years. This paper will use case studies of law reform from Asia, in particular Southeast Asia, to show that the policy considerations of governments in reforming their laws were often quite different from the standard rationale mentioned above. As much of the IP was, at least initially, held by foreigners and introduced to attract foreign investment, national development considerations were joined with the more commonly quoted objectives to promote the rights, creativity and innovation of individuals. Such national development objectives at times coincided and at other times collided with official explanations and received wisdom about the effects of stronger IP rights.

Especially in the early postcolonial period, copyright laws and other IP laws were frequently restricted or simply not implemented, if they conflicted with development policies in areas such as education or public health. Such policies were slowly changing in the wake of WTO-TRIPS and other international agreements. Nevertheless, the implementation and enforcement of the IP laws has been uneven. Specialised institutions such as courts and IP administering agencies compete with other branches of government and administration for limited funding and a rich repertoire of informal dispute settlement procedures has kept the number of court cases relatively low. In some countries, censorship laws have influenced freedom of expression and led to quite idiosyncratic interpretations of intellectual property laws. Governments often also retain a role in the assessment of licensing and technology transfer contracts. And while there are many programs to foster individual creativity, in most cases R & D activities are still largely taking place in government institutions and this has influenced the thinking about intellectual property rights and creativity in the context of employment.

The paper uses a few case studies to examine the implementation of IP laws in selected Asian developing countries to point to the quite different institutional setting for IP law reform in comparison to European or American models. It reaches some tentative conclusions as to the likely effects on creativity and innovation under these different circumstances.
