![]() The gap in birth year between the discus groups was smaller, in that it was just under a six-year difference (1964.7 for men versus 1959 for women). The men's shot put group had an average birth year of 1969 compared with an average birth year of 1959 women's shot group. Large differences in birth year were observed between the genders for both shot put and discus groups. Tables 1 & 2 lists the average birth year, age, age of personal best (PB) and the high and low PB for each for each gender of each throwing event group. The averages for the remaining ages were then divided by the average for the best year to yield a percentage that less than 100 percent. The age with the highest average performance of the group was assigned the value of 100 percent. To determine the percentage of a group's overall performance, the average distance for all twenty-four throwers was averaged for each year at each age between the ages of 18 to 30. It should be noted that the percentage of the group's best performance as a whole, in a given year, can be different from the average age in which the personal best was achieved for the group. The percentage of the group's performance relative to their best performance year for each year between the ages of 18 to 30. ![]() Average distance for each group for each year between the ages of 18 to 30 years of age.ĥ.

Performance data for the top 24 throwers of all-time for each gender (there were only 23 for the men's javelin) in the four throwing disciplines (hammer, shot put, discus and javelin) was analyzed to determine the following values:ġ. Development rates between the four throwing disciplines will also be examined for female throwers and a comparison between both genders in all four throwing disciplines will be carried out to determine any developmental differentiation among elite level performers. These analyses were performed in an effort to determine how long it will take to reach the highest level of performance in each of the four throwing events, which in turn should help coaches and athletes set realistic goals and timetables for future athletic development. This study is an extension of a previously published article by Babbitt and Saatara (1), which concentrated solely on the development rates of male throwers. While all of these disciplines are grouped as throwing events, they are each very distinct in their own way, with the implement weight ranging between 600g to 4kg for the women and 800g to 7.26kg for the men and elite level release speeds spanning from 13 m/s for shot put up to 30 m/s for the javelin. The focus of this article will be concentrated on a statistical data analysis to identify the developmental rates and age based performance patterns for elite performers in the four throwing disciplines within the sport of athletics (shot put, discus, hammer and javelin). For this reason, the throwing events have been defined as sports of repetition. Execution of these events at the highest level requires a combination of speed, power, coordination and flexibility, which can take many years to develop and refine. The throwing events in the sport of track and field are some of the most powerful activities in the world of athletics.
