The purpose of this paper is to discuss the health and well-being benefits of outdoor, cold water swimming.

This paper describes the personal experience of one cold water swimmer. It also explores some of the research literature suggesting there is evidence of the benefits to the health and well-being of people of all ages.

The paper explores literature suggesting there is evidence of the benefits of “blue therapy” to the health and well-being of people of all ages.

This paper describes the personal experience of one cold water swimmer. However, a growing body of published literature suggests there is value in “blue therapy” informing future social prescribing programmes.

There has been an increase in swimming in natural bodies of water as reported in personal qualitative accounts. However, limited academic research has explored the meaning of this occupation. Engaging with nature, exercising and being part of a community contribute to better mental and physical health. The purpose of this research was to explore the meaning that adults attribute to open-water swimming in natural bodies of water.

This study used phenomenological interviews to explore the meaning that five adults attribute to open-water swimming.

Open-water swimming contributes to meaning-making in many ways. Participants reported swimming as necessary for maintaining mental and emotional well-being and forming meaningful connections with the social environment, nature and their true selves.

This study contributes to the understanding of the meaning of open-water swimming for adults in Ireland. Understanding the meaning of this occupation may add to the body of evidence exploring blue-space to promote health.

Open-water swimming is an occupation growing in popularity. This is the first paper to explore open-water swimming from an occupational perspective. This may provide an alternative perspective for viewing blue-space engagement and understanding the relationship between health, blue-space occupations and our oceans.

The orthodox view about women in sport is that, when compared with males, females have always held, and will always continue to hold an inferior position in sporting achievement.

The purpose of this study is to address magnetohydrodynamic (MHD) bioconvection caused by the swimming of oxytactic microorganisms in a linearly heated square cavity filled with porous media and Cu–water nanofluid. The effects of different multiphysical aspects are demonstrated using local distributions as well as global quantities for fluid flow, temperature, oxygen concentration and microorganisms population.

The coupled transport equations are converted into the nondimensional partial differential equations, which are solved numerically using a finite volume-based computing code. The flow of Cu–water nanofluid through the pores of porous media is formulated following the Brinkman–Forchheimer–Darcy model. The swimming of oxytactic microorganisms is handled following a continuum model.

The analysis of transport phenomena of bioconvection is performed in a linearly heated porous enclosure containing Cu–water nanofluid and oxytactic microorganisms under the influence of magnetic fields. The application of such a system could have potential impacts in diverse fields of engineering and science. The results show that the flow and temperature distribution along with the isoconcentrations of oxygen and microorganisms is markedly affected by the involved governing parameters.

Similar study of bioconvection could be extended further considering thermal radiation, chemical attraction, gravity and light.

The outcomes of this investigation could be used in diverse fields of multiphysical applications, such as in food industries, chemical processing equipment, fuel cell technology and enhanced oil recovery.

The insight of the linear heating profile reveals a special attribute of simultaneous heating and cooling zones along the heated side. With such an interesting feature, the MHD bioconvection of oxytactic microorganisms in nanofluid-filled porous substance is not reported so far.

This paper investigates the energy performance of aquatic centres in Victoria.

Physical and occupancy characteristics and energy consumption from various centres were analysed to understand the interrelationship between numerous factors that contribute to the energy consumption of these facilities.

The energy usage intensity of the facilities ranged from 632 to 2,247 kWh/m2 or 8 to 17 kWh/visit. Primary and secondary indicators were examined to find the key performance indicators.

This study sheds some light into the overall energy performance of aquatic centres in the temperate climate of Australia. More samples need to be collected to perform rigorous statistical analysis leading to a reliable benchmark model. System-wise investigation of energy consumption is required to determine where the energy is being used and the saving potentials of each system.

This study has arisen from the need of managers of large aquatic and recreation facilities to benchmark the energy consumption of their own facilities. This study will fill the gap that currently exists in the area of energy rating systems for aquatic centres.

The results of this study showed that aquatic centres consume around seven times more energy than a commercial office building. Thus, if the energy consumption of aquatic centres could be reduced by as little as only 10 per cent, at least 3.5 million tonnes of carbon dioxide emission can be reduced.

Environmental design standards for aquatic centres have generally been overlooked due to the complex nature of these buildings. As a result, this sector suffers from a general lack of both qualitative and quantitative information and benchmarking.

The purpose is to present parameters of a new design code, which is intended to control the indoor air environment for sports buildings in China.

Based on requirements of international sports federations the characteristics of indoor airflow of sports buildings in China, include the parameters of indoor air environment of gymnasiums and natatoriums, air velocity, temperature, humidity and fresh air volume. Some illustrations and considerations are shown too.

Compared with the international standards and design guidelines, the Chinese new design code has more detailed parameters for high level sports game.

Not all the indoor air parameters of the code are mentioned in this paper. The designs of sports building are built for high level sports games in recent years of China, the parameters of class A are paid more attention to in the paper.

The contents of paper could be the major designs in heating, ventilation and air conditioning system in sports building.

This paper could be a guide to advice the designing of indoor air environment of sports building, especially for the Beijing Olympic game in 2008, and is useful to help advanced HVAC design and analysis on the similar large space buildings.
