Comparing Age Group USAT Scores

In my last post, I compared the number of athletes competing in different multi-sport events, to see if the numbers were going up or down. I found that the numbers in some of the events were not exactly what I thought they would be. And then I began to wonder if the athletes competing were getting faster or slower, and at what rate it was happening. I understand that when comparing 35-39 age groupers against 55-59 age groupers, the first group should be faster, but were they slowing down at the same rate, across the board. I used the points system of USA Triathlon (USAT) and used the ranked athletes only, because they have an average of races and using unranked would give me athletes that had only done one race. Using an average should stop outliers, and I do understand this has its own issues, but it should give some food for thought. Here is a link to the explanation of the point system within USAT.
I took the top ten scores from all five sports and the same age groups used in the last blog. The numbers show that not only were there more athletes in the 40-44 age group than the 35-39 age group, but their scores were .67% higher than the younger age group. The 45-49 age group had fewer athletes than the 40-44 age group, but 45-49 age group scores were 3.83% lower than the 40-44 age group. The number for the for all the age groups and sports are below in the table. With regular triathlons, the rankings do exactly what one would think, they steadily decline after the 40-44 age group.
Aquabike showed the same as triathlons, the 40-44 age group saw an increase from the 35-39 age group, and then the 45-49 age group scores start to decline. The interesting thing is the percentage increased at far greater rate than triathlons, and the decrease from 45-49 age group from the 40-44 age group was far less than that of triathlons. It is interesting to see this, but with the removal of the run leg it is more than likely easier maintain the same level speed until the age of 50 for men. As with triathlons, aquabike age group 50-54 had a decrease in scores, but the average of the decrease for the top ten was 4 times as much for triathlons. One reason for this is there are fewer people doing the aquabike than triathlons. It is still interesting data, and I would be interested in doing an individual year to year analysis, instead of a group analysis.
What are your thoughts on declining scores and differences between the different sports?
