Talent identification in sport: practices and issues.
A basic definition of talent identification (TI) encompasses the recognition of a natural endowment or ability of superior quality. But, identifying a talented athlete within sport is multifaceted and complex. Talent in sport is identified by characteristics that are at least partially genetically determined, affected by numerous environmental conditions and currently difficult to determine accurately. (3)
The disparity between practice and theory involved in TI has become apparent and, while researchers are currently closing this gap, the advent of gene mapping and the subsequent potential for gene testing and therapy have added a new dimension to this endeavour.
Systematic approaches to TI
Systematic TI is no new phenomenon. Several countries, in particular the former 'Eastern block' countries, have applied systematic TI since the 1960s and early 1970s with astounding results during the Olympics of 1972, 1976 and 1980. These successes were ascribed to their thorough TI processes adopted in the late 1960s. (4)
Western countries also initiated systematic TI programmes, albeit with their own unique variation and mostly without the associated political ideology. Australia was the first Western country to implement such a programme, the Sport Search Programme, in 1994. (5) South Africa, in an endeavour to find solutions for the disproportionate representation of the South African population in representative teams, commissioned research in the early nineties to investigate solutions to the problem. (6) An adapted version of the Australian sport search programme was subsequently applied in the late nineties, and follow-up sport-specific programmes involving selected national sport federations were planned, but all these efforts lost momentum with continuous changes in the national governance of sport.
Other countries such as the UK also adopted the Australian concept of TI and embarked on a systematic and organised approach. However, these systematic approaches to TI, although very inclusive, proved to be very expensive and the returns did not seem to justify the costs, especially for team sports. Subsequently, more focused approaches that rely on multidisciplinary inputs have been initiated with evidence of more success. (3)
Gene mapping and therapy for sports doping
The elucidation of the complete human genome with approximately 30 000 different genes has led to new possibilities, not only for the diagnosis and prevention of a wide variety of diseases, but also for the purpose of TI. Close to 200 genes, or loci linked to or associated with human performance and health-related fitness, have already been identified. (7) Testing such genes, some propose, can be a legitimate aspect of TI and training programme development--a valid adjunct to current physiological, biochemical and psychological testing. (8) Gene technology companies are already supplying testing kits for the purpose of identifying selected genes (e.g. www.gtg.com.au).
In addition, the knowledge of gene mapping may be used for the design of new therapeutics, including gene therapy, based on DNA sequence information. Gene therapy may not only be applied for the treatment of serious diseases, but also for less life-threatening situations or injuries such as sports injuries. (9) In addition, athletes may be able to use gene therapy to improve their bodies for better performance. Many genes with the potential to enhance athletic performance are available. The most relevant of these for performance enhancement are erythropoietin (EPO), growth factors, myostatin and endorphins. (9)
Gene therapy also opens the door for gene doping, a practice disapproved by both the International Olympic Committee ... and the World Anti-Doping Agency.
Risks of gene doping and ethics involved in the detection thereof
A number of risks are associated with gene doping, especially where gene transfer vectors are produced in non-controlled laboratories. (9) Furthermore, the detection of gene doping is currently very difficult and evokes many ethical concerns. (10)
While the need for TI practices and the drive for countries to prove dominance at major international competitions remain, researchers are interrogating the scientific justification for current and past practices and are calling for more focused research in this area. For a more comprehensive evaluation of current practices see the academic review commissioned by Sport Scotland. (4) These endeavours to find more appropriate methods of TI will continue as long as the drive for success in the international arena persists. Although gene testing and gene therapy/doping have the potential to dominate TI in the future, the myriad of ethical issues and health risks of disreputable therapy practices may delay its impact.
