Sport And Green House Gases

The Globe This chapter looks at the relationship between sport and the (Eco)environment; The first to do so in 1997 and now highly relevant in 2008. The financial crisis of late 2008 may distract from Carbon pollution issues; so we might now be destroying our man made systems(money) and biological system( from pollution). As we enter the next millennium, it seems we have all but destroyed our environment (Fig.1). Doctors may soon be standing helplessly by as our children exercise and play sport in the disease-ridden scrap yards of the planet. John Hunter, the intrepid eighteenth century surgeon/scientist, set the pace for development and research in medicine but we have lagged behind. The initial successes with anaesthesia, infectious diseases, antibiotics, open heart surgery, artificial joint surgery and vaccinations have fallen short with unrealistic expectations of the Genome Project. We should be ashamed of our failure to cure cancer and HIV disease (despite the resources available) and to confront environmental problems. Rapid population (Fig.2) and industrial growth with associated pollution and resource exhaustion are precipitating a global disaster. Increased life expectancy has resulted from higher living and social standards, public health measures, education and biomedical advances. Recently this has been achieved by the education of young women and family planning. However this success is pushing us towards a globulal population of 11 billion by 2100. We must face-up to the resulting tropical forest destruction, soil erosion, water and air pollution and global re-warming. We can no longer reign supreme over the environment thinking that technology and science will fix the problems. Recent civilization (last 50 – 150 years) has led to the modern City – with its dense urban population, homelessness, poverty and the creation of an unhealthy “underclass” from rapid movement between countries and the collapse of public health infrastructure. The Big City is merely a military citadel (creating an urban hell within) and squandering vital resources. The “top” eschelons are well but the “underclass” are as sick as the Irish city dwellers of the 1930s and not much better off than the hunter-food gatherers of the Stone Age. The old diseases have re-emerged; TB is at the highest rate in history (one-third of the world’s population), the bubonic plague is present in major US cities and an extra 50 to 80 million cases of malaria are expected each year.

2 Just as the Battle of Waterloo was won on the playing fields of Eton so might the problems of the environment be solved at Olympia . Perhaps not entirely unrealistic. After all the Olympic Games are the highlight of sport and are dedicated to idealism and the Glory of Zeus, (the mind, body and spirit of man). Baron Pierre de Coubertin said “The Olympic movement tends to bring together in a radiant union all the qualities which guide mankind to perfection.” Athletes, their trainers and health carers and their spectators should care about not only their bodies but their environs. There seems little sense in a perfect performance in a planetary junk-yard (Fig. ). The culture of sport needs a new creed. At the 2008 Beijing Olympics, there were great concerns re the effect of the severe air pollution affecting performances and athletes health. ES was in Beijing 9 months earlier and found it hard to breathe in that city. However, China managed to cut car road users and industrial emissions over this period. Such extraordinary measures may only be possible in State monopolies.          The creed ... For the athlete of the Next millennium will be:   ∙            I will protect my body   ∙            I will protect my environment              

     

Protecting the body means not embarking on training schedules and techniques which have adverse health effects. Rigorous performance schedules for gymnastics and women’s events may precipitate menstrual dysfunction and eating disorders with both short term (malnutrition, starvation) and long term consequences (osteoporosis, hip and vertebral fractures). The dangers of blood doping and performance enhancement drugs are described in Chapter 4. Athletes using such drugs, especially steroids, are sacrificing their bodies for short-term achievements. The I.O.C. has rightly taken a hard stand on drugs in sport. Protecting the environment means athletes and their associations insisting upon protection of their environment. If the purpose of sport (exercise) is to enhance our health (physically and intellectually), then it is irrational and dangerous to exercise in a polluted environment (the main determinant of our health status). Athletic events should only be staged in cities and countries with a commitment to safe and clean environments. The alternatives are clear. The urban athlete inhales above average quantities of air pollutants (when resp minute volume increases up to 20 x ) which bypasses the nose (filter) with the open mouth (after R J Shephard, 1984). There is: drying of the airways, possible cold/dry air induced bronchospasm, respiratory muscle fatigue and the toxic effect of pollutants. Such effects are maximum in marathons and road races (cycle/foot). Air pollutants are either reducing or oxidant forms of smog. Reducing forms (carbon fuels) consist of smoke particulates, SO2 or SO3. These may induce bronchospasm with later respiratory infection and viral myocarditis, especially in children in big cities. Oxidant forms (vehicle exhausts with sunlight) are CO, hydrocarbons, ozone and nitrogen oxides. These agents affect athletic competition. CO may be lethal (cardiovascular death in elderly and possibly in the young athlete in competition). Swimming times are slower when levels exceed 30 ppm. Ozone and nitrogen oxides impair the respiratory system. Competitive cyclists on open roads absorb lead emitted from cars increases with training. Similarly, amateur cyclists suffer airway irritation from ozone.  Team doctors have been required to advise on accommodation in smog ridden cities, identify congested roads for athletes to avoid (80% of CO comes from cars; pollutants concentrate in tunnels). Training has been curtailed when ozone levels were high. Whether adaptation to pollutants occurs and is desirable is debatable. There must be an awareness of the need of econolgoical compatibility of athletic performance with the environment in which they are competing. Following Olympic Games such as the Sydney 2000 Games are being planned with this in mind. “Greening-up for the Games” means these Games are being staged in sympathy with the needs and

protection of the environment (Fig.4). The construction of the Olympic Stadium at Homebush Bay (a 760 hectare site of saltmarsh and wetlands which was previously an industrial dump) has provided the impetus for the biggest and perhaps the "greenest" single urban remediation. This has involved the preservation of a number of valuable animal (the rare green and golden bell frog) and plant species. Engineers have constructed a system of sub-surface drains to collect lechate from contaminated materials to send (isolated from the natural habitats) to treatment areas. The development of the facilities is being based on the principles adopted at the 1992 U.N. Earth Summit. These 2000 Games are being held with a commitment to energy and water conservation, waste minimisation, air, water and soil quality and protection of cultural and natural environments. In particular, it is intended to use passive solar building design, collect wastewater for recycling and protect natural nearby ecosystems. Precious resources should not be squandered. It is important to avoid constructing huge Olympic monuments to excess and waste with a legacy of poor future usage and a financial burden for coming generations ( Montreal 1976) nor to dangerous Political Ideologies (Nazism Berlin 1936; Communism post-1956, Commercialism in the 1990s). Jack Lovelock (NZ) single-mindedly won the glamour event of the 1500 m in Berlin 1936, blithely unaware of the Nazi funfare about him (Fig. 5). The Medic-O-Games (Medical Olympics) – Inaugural meeting in Sydney 1997 will provide a forum for medical doctors to discuss the health and environment problems facing us over the next millennium and to participate in Olympic sporting events themselves. Its aim is to harness the Olympic spirit to restore idealism to the practice of medicine. Doctors and sports medicine specialists need to be aware of the impact of an (adverse) environment on health and their athletes). They need to know how to detect and diagnose environmentally related problems, identify environmental hazards and appropriately advise patients/athletes. Physicians in the USA are joining the US Environmental Protection Agency in the desire to preserve the environment and promote global health. It is a new concept of harnessing the Olympic Spirit which should establish an environmental model for the next century and a medical metropolis.                Fundamentals of       Sport and the Environment   Our environment determines Our health status   ∙
