How does Age affect improvement in CrossFit?

Last year we released an article entitled How Long Does It Take To Improve In CrossFit? Using “Fitness Level“, our robust measure of an athlete’s physical capacity, we looked at improvement rates across all levels and abilities. We found that, on average, it takes about 5-6 months to improve your overall Fitness Level by 10 Levels (e.g. going from a level 60 to a level 70).

We then followed up that analysis with Working Out More: Is It Worth It? In it, we looked at the affect of the number of workout days per week on improvements to Fitness Levels. We discovered that working out 5 days per week produced a 27% faster improvement over working out 3 days per week.

In this article, we’ll be throwing age into the mix. We’ll explore the relationship between an athlete’s Age and improvement time in CrossFit. How much of a difference is there in improvement times between a 25-year-old and a 45-year-old? This is an especially important question when considering the validity and necessity of age divisions in competitions, such as the various Master’s Divisions at the CrossFit Games.

After analyzing the data, we found that there is a strong correlation between an athlete’s age and how long it took them to improve their BTWB Fitness Level by 10 levels. As an example, on average, it took 45 year old athletes nearly 2 months longer (32% longer) to improve from a level 60 to a level 70 when compared to their 25 year old counterparts. Read more…
