Introduction
One of the challenges facing the United States Olympic Committee and member
national governing bodies today is athlete identification and development The essence of the dilemma is how to most effectively identify and focus developmental resources on those athletes who have the greatest chance of international success During the last year I collected biographical and survey data on medal winning World Cup biathletes to understand the path of athlete development In addition, I conducted interviews with coaches and sport scientists from Germany, Russia, and Sweden, which provided further details on development By
understanding the patterns of athlete development comparisons can be made between
successful programs and current U S programs These data reveal a tremendous amount of information about the length of time and support that is necessary to develop elite endurance athletes Therefore, the purpose of this paper is to outline clearly the time course and pattern of athlete development in world-class biathletes and canoe/kayak athletes A second objective is
to synthesize this information into models of athlete development
Trang 3CURRENT TRENDS ON THE BIATHLON WORLD CUP
International Biathlon Union Biographical Information
Before attempting to design optimal models of athlete development, it is critical to know the time course and developmental patterns of the world’s best athletes Data from the 1996-97 International Biathlon Union calendar book allows us to view athlete age at critical milestones These data are compiled from the top 35 men and top 35 women who are currently competing on the Biathlon World Cup and have placed in the top three Figure 1 illustrates the average age at critical milestones during athlete development Men enter the sport at age of 15.2 with a standard deviation of ±3.7 and women at 18.5 (±3.6) Women, however receive their first medal at the age of 23 (±2.6) and men at 24 (±2.1) Variability of age at critical milestones is assessed by standard deviation
Trang 4Figure 1 Average age at critical milestones of current medal winning biathletes
from the International Biathlon Union biographical data
The average number of total years in the sport for men is 13.0 years of ±3.4 and women 7.8 years (±3.2) Over two-thirds of the men have been in the sport between 9.6 and 16.4 years
For the women, two-thirds fell between 5.6 and 12.0 years The number of years needed to win
the first medal in World Cup, World Biathlon Championship, or Olympic Winter Games (WC,
WBC, OWG) is 8.8 (±3.2) and 4.5 (±2.8) years for men and women, respectively Current
mean age of the competitors is 26.3 (±2.7) and 28.2 (±2.7) for women and men, respectively
These small standard deviations show the significant strength of the results Table 1 describes
the range (minimum and maximum) in ages and years for biathletes placing in the top three

Trang 5• First, women have been competing in the sport for less number of years than the men
The first WBC for women was in 1984, the first WC in 1989, and the first OWG in 1992 in Albertville, France For men, the first WBC was held in 1958, the first OWG in 1960 in Squaw Valley, California, and the first World Junior Championship in 1967 At this year’s World Championships 27 countries entered men’s teams and 24 entered women’s teams At the World Junior Championships 26 countries entered men’s teams and 19 entered women’s
• Second, the depth of the field of the women is not as great as the men
This is reflected by a greater time difference between first and 25th place Women have come from other endurance sports such as cross country skiing and distance running and have
succeeded on the World Cup in a short period Talented athletes such as current overall World Cup Champion, Magdalena Forsberg of Sweden, double gold Olympic champion, Myriam Bedard from Canada, and Shumei Yu of China have placed in the top three within two years of entering the sport
Trends in Yearly Improvement on the World Cup
Data from the last 12 years for men and the last four years for women clearly show that the field is skiing faster and taking less time at the range Women are making the most
improvement regarding total time, ski velocity, and shooting time In 1992, the average age of the top three male competitors was 24 and in 1997 was 28 years old With a few exceptions, the field of athletes remained the same, but grew older For women, the average age is 24-26 and has remained the same for the last five years The older women are winning the Sprint races and the younger women are capturing the Individual races Table 2 presents data showing the yearly improvement in Biathlon performance (from J Wick, 1997 IBU Trainers Seminar, Leipzig, Germany)

Table 2 Yearly improvement in determinants of Biathlon World Cup performance and
current shooting performance
Trang 6Total time (ski time, shooting, and penalties) for men and women has decreased yearly
As demonstrated by the data, all factors of performance have improved No longer will an athlete win on one attribute To be successful, a fine synthesis between skiing velocity and shooting performance must occur
USBA/USOC International Survey
Twenty-eight current and former medallists completed a survey documenting their development in Biathlon Athletes who had placed in the top three in the last ten years
completed the survey One of the objectives of the survey was to document the amount and type of training from the ages of five to 15 A second objective was to detail how much
coaching and training occurred after specializing in biathlon A third objective included
documenting and understanding the time course of development from the time an athlete enters the sport to winning an Olympic medal These data provide additional details in support of the biographical data and the notion of long-term development that is necessary for success in Biathlon It should be noted that the sample size of the survey is small (n=28); nonetheless it does shed some light on development Table 3 illustrates the time course of development Sixty percent of respondents were from Germany and Russia, the most successful biathlon programs
in the history of the sport Other respondents were from Belarus, Canada, France, Sweden, and the United States These data show that at the average age of 11.7 these athletes entered their first cross-country ski race From the ages of 5-15 they were participating in a variety of sports such as cross country skiing, alpine skiing, figure skating, track and field, soccer, gymnastics, and swimming Participation in these activities is essential for developing general coordination that forms the foundation for specific coordination (Drabik, 1996) Developing motor skills

Table 3 Age at critical milestones of development in medal winning Biathletes
(USBA/USOC international survey)
Women enter their first biathlon race at age 19.3 and men earlier at age 14.9 To be successful biathletes must begin racing between the ages of 15-18 Women and men exhibit similar patterns of ascendancy at World Cup and Olympic competition Once a top 25 World Cup result has been achieved, it takes 1-2 years for athletes to medal in international
competition A top 25 result occurs at age 22, at top 10 placing at age 23, and a medal at 24 These data suggest that the preparation period leading up the age of 22-23 is crucial for
success This is a “critical period” for physical, technical, and mental development In
countries such as Germany and Sweden, biathletes aged 16-22 receive a tremendous amount of education and support to help them in their development This six-year age group is where successful programs provide support for talented athletes Athlete support comes from daily coaching, sport-specific education programs (physiology, biomechanics, and sport psychology), sports science and medicine services, career and academic counseling for the athlete, and education programs for coaches
Figure 2 describes the first regular and organized training of winning World Cup
biathletes On the average, top biathletes begin cross-country skiing at the age of 11
Successful biathletes have a minimum of four years of cross-country skiing before entering
Trang 8their first biathlon race The first structured training program (three days per week) for cross country or biathlon starts at age 16 for women and age 13.7 for men and lasts for an average of 9.8 months per year Daily coaching for biathlon begins for men at age 14.8 and for women at age 20 Clearly, early regular training in Biathlon during the ages of 15-18 is necessary to be
successful
Figure 2 Starting age of organized biathlon and cross-country ski training.
The top biathletes indicated they needed on the average 3.6 years of shooting before attaining 80% accuracy and 5.5 years before attaining 95% accuracy Attaining 95% shooting accuracy is the result of daily coaching
Models of Athlete Development
Trang 9Figures 3 and 4 illustrate models of optimum development for current medal winning Biathletes This represents a compilation of data from IBU biographical information, USBA/USOC international survey, and interviews with German, Russian, French, Finnish, and Swedish sport scientists and coaches From these models, it is clear the length of time that is necessary for an endurance athlete to develop into a world-class competitor This path of development is common to all successful biathlon programs

CURRENT TRENDS IN CANOE/KAYAK
U S Canoe and Kayak Competitive Excellence Study
Trang 12To understand the development progression of internationally successful canoe and kayak athletes, U S Canoe/Kayak (Henderson and Endicott) identified more than 100 athletes who had placed in the top 3 in Olympic Canoe/Kayak events over the past 15 years Eighty-five athletes completed a questionnaire with eight questions Figure 5 shows the average at critical milestones
Figure 5 Average age at critical milestones in canoe/kayak events
Canoe/kayak athletes begin competing early at the age of 12.3 with a standard deviation
of ±1.9 Eighty-seven percent of athletes who placed in the top 3 at World Championships started racing before the age of 14 Of the 61 athletes who became a World Champions, 34 of them placed in the top six at World Junior Championships Once athletes begin competing at the World Championships (20.4 ±2.3) they medal within two years at the age of 22.2 ±2.9 Variability as measured by standard deviation is narrow at all ages From the data there
emerges a clear path of development As author Dan Henderson points out, most of the

Figure 6 Average age at critical milestones in Biathlon and Canoe/kayak.
This canoe/kayak model is an example of systematic athlete development Henderson makes the point, “In the United States, I believe that we have focused entirely too much on what
we perceive to be the exceptional few who do not fit the strong trends in this study We have counted on our athletes to be exceptions to the norm of how the rest of the world develops canoe/kayak athletes.” Both the biathlon and canoe/kayak models exhibit similar patterns of development as depicted in Figure 6
Biathletes and canoe/kayak athletes ascend very quickly to the top eight or top 10 after some initial exposure to World Cup or World Championship competition On the average, it takes one year to achieve top 8 or top 10 status after entering canoe/kayak World
Championships or placing in the top 25 in the Biathlon World Cup From that point, one

Trang 14additional year is needed to place in the top 3 in World Cup or World Championship races What explains this rapid and linear progression? Interpretations of the data suggest strong junior programs and systematic training are the main reasons The basis of systematic training
is daily coaching with sport science support for 4-6 years Most of the preparation and training are done before entering international senior competition At that point, athletes and coaches fine-tune training to achieve increases in performance In both models most of the data are from athletes of Eastern or Central European countries These countries are known for their well-developed club and national team programs that systematically train athletes over a long period
