During the last twenty years, a remarkable new type of service has been developed in the world of sports, which can be described as the indoorisation of outdoor sports. Typical outdoor sports like climbing, skiing, surfing, rowing, and skydiving, which used to be exclusively practiced in a natural environment of mountains, oceans, rivers and the air, are now being offered for consumption in safe, predictable and controlled indoor centers. The present article emphasizes the rise of indoor lifestyle sports, such as rafting, snowboarding, skydiving and surfing. It discusses the conditions under and ways in which commercial entrepreneurs in the Netherlands have created this market, the meanings that they have ascribed to their centers and the dilemmas with which they have been confronted. It is argued that the rise of this economic market cannot be understood if it is solely interpreted as the result of economic, technological or natural developments. These economic activities were also embedded in and influenced by shared understandings and their representations in structured fields of outdoor sports, mainstream sports and leisure experience activities. A better understanding of the indoorisation of outdoor lifestyle sports can be achieved by recognizing how these structures and cultures pervaded the rise of this new market.

For twenty years, typical outdoor lifestyle sports like rafting, snowboarding and rock climbing, which used to be exclusively practised in natural environments, are being offered in controlled artificial settings. This process can be described as 'the indoorisation of outdoor sports'. With this development, questions of authenticity arise. Are these new, commercial forms still authentic lifestyle sports? And can we consider the participants in these indoorised lifestyle sports as authentic? There has been a discussion about authenticity in lifestyle sports since its worldwide popularisation and it is worth to reconsider this discussion against the background of new, commercial versions of lifestyle sports. Therefore, in this paper a qualitative analysis is offered about the consumption of a constructed authenticity in a cultural context increasingly characterized by artificialization.

An important performance determinant in wheelchair sports is the power exchanged between the athletewheelchair combination and the environment, in short, mechanical power. Inertial measurement units (IMUs) might be used to estimate the exchanged mechanical power during wheelchair sports practice. However, to validly apply IMUs for mechanical power assessment in wheelchair sports, a well-founded and unambiguous theoretical framework is required that follows the dynamics of manual wheelchair propulsion. Therefore, this research has two goals. First, to present a theoretical framework that supports the use of IMUs to estimate power output via power balance equations. Second, to demonstrate the use of the IMU-based power estimates during wheelchair propulsion based on experimental data. Mechanical power during straight-line wheelchair propulsion on a treadmill was estimated using a wheel mounted IMU and was subsequently compared to optical motion capture data serving as a reference. IMU-based power was calculated from rolling resistance (estimated from drag tests) and change in kinetic energy (estimated using wheelchair velocity and wheelchair acceleration). The results reveal no significant difference between reference power values and the proposed IMU-based power (1.8% mean difference, N.S.). As the estimated rolling resistance shows a 0.9–1.7% underestimation, over time, IMU-based power will be slightly underestimated as well. To conclude, the theoretical framework and the resulting IMU model seems to provide acceptable estimates of mechanical power during straight-line wheelchair propulsion in wheelchair (sports) practice, and it is an important first step towards feasible power estimations in all wheelchair sports situations.

Sports are activities enjoyed by many across the globe, regardless of age. The existence and promotion of youth sports has often been based on various assumptions about its value and role in society. Sports participation is assumed to be fun and good and is assumed to contribute to the development of young people. As a result, sports are often seen as an essential part of life for youth. Participation in sports and physical activity is assumed to help young people to develop in a context in which they are able to learn important positive societal values (Fraser-Thomas et al., 2005; Holt, 2008). Although there is a widespread belief in the positive dimensions of sports participation for young people, there is a need for research and theory that identifies and critically looks at the processes through which sports participation by youth is experienced and shapes their lives (Coakley, 2011). I return to this critical perspective after I elaborate on the ways sports are viewed as important effective activities for positive youth development.

Today, Dutch National Non-profit Sports Organizations (NNSFs) experience financial pressures. Two indications for this are described in this paper i.e. increased competition in the sports sector and changes in subsidy division. Decreasing incomes from subsidies can be compensated with either increasing incomes from a commercial domain or increasing incomes from member contributions. This last solution has been the motive for the increasing interest in the use of marketing techniques as a solution for the growing uncertainties. Many NNSFs have participated in a special marketing program in order to enlarge their marketing awareness and create a marketing strategy. This paper deals with possible impediments resulting from the implementation of the marketing strategies. It is primarily based on a literature review, however, the first results from a qualitative research to the increasing use of marketing techniques among NNSFs provides insights in the experienced impediments of NNSFs .

The scope of technology has expanded towards areas such as sports and vitality, offering significant challenges for engineering designers. However, only little is known about the underlying design and engineering processes used within these fields. Therefore, this paper aims to get an indepth understanding of these type of processes. During a three-day design competition (Hackathon), three groups of engineers were challenged to develop experience-able prototypes in the field of sports and vitality. Their process was monitored based on the Reflective Transformative Design process (RTD-process) framework, describing the various activities part of the design process. Groups had to keep track of their activities, and six group reflection-sessions were held. Results show that all groups used an open and explorative approach, they frequently swapped between activities, making them able to reflect on their actions. While spending more time on envisioning and creating a clear vision seem to relate to the quality of the design concept.

Furosemide is included in the World Anti-Doping Agency’s (WADA) list of prohibited substances because it can be used by athletes to mask the presence of performance-enhancing drugs in urine and/or excrete water for rapid weight loss. But how effective is furosemide in masking prohibited substances in urine? Based on the pharmacology and the available literature, we conclude that the masking effect of furosemide is limited. Furosemide is a doping agent that is mainly relevant for sports with weight categories. Conflict of interest and financial support: none declared.

Almere is a green city where the greenery extends into the centre through a framework of nature, forests, parks and canals. With this green environment, Almere fulfils an important condition for a liveable city, where it is pleasant to live and work. An important goal for the municipality is to challenge its residents to develop a healthy lifestyle by using that green framework.But what really motivates Almeerders to go outside to exercise, enjoy the surroundings and meet each other? Are there sufficient green meeting or sports facilities nearby? Could the routes that connect the living and working environment with the larger parks or forests be better designed? And can those routes simultaneously contribute to climate adaptation?With the Green Escape Challenge, we invited students and young professionals to work on these assignments together.

This study analyses how the social construction of integrity takes place within the context of football in the Netherlands. Combining a contextual approach to sports integrity with the analytic lens of sensemaking, this qualitative multi-method case study analyses – in one extreme case in Dutch youth amateur football – why and when the ‘incident’ was perceived as an ‘integrity issue’, and how the meaning of (the) integrity (issue) was socially constructed by (interactions between) stakeholders involved in the case. Our findings show why, when, and how moral norms and values are (not) debated and at stake, and that the social construction of sports integrity is intertwined with the institutional context and the role of secondary stakeholders. It provides insights that can help sports organizations to identify risks in their moral sports culure and to develop measures or policies to safeguard integrity in sport.
