Have you heard of linear progression? Read Starting Strength? Maybe you have seen the chart in The Science and Practice of Strength Training or read elsewhere that long term strength gains over time are logarithmic. Today, thanks to the massive Oly Stats database, we have a model for weightlifting performance over time...and it is not logarithmic. The analysis laid out in this blog post will provide two equations, one for each sex, that describe performance over time. For you stats nerds out there, this is an initial study to provide a descriptive model, not a predictive one. Further studies will dive more deeply into the data.
