Data Science Asked on December 28, 2021
TL;DR: I’m doing a fairly basic project which involves exercise. It seems that descriptive statistics and basic data vis (ex: line graph) would be most appropriate for this project, but I wonder if you have any recommendations for analyses.
For this project, I am performing the same set of 15 single-joint exercises each week (we’ll call these “Exercises”). Every 4 weeks, I’m performing 3 different multi-joint exercises (we’ll call these “Lifts”). My goals are to:
My hypothesis is that my strength gains from the Exercises I perform will transfer well to the strength gains from the Lifts that I perform.
The design is a bit janky (and it’s more of a correlational study design than an experimental design), but this project is mostly just to demonstrate data collection and basic data analysis concerns. However, I’d like to make the analysis as interesting as possible. So far, it seems that basic descriptives are the best way to analyze this data, with something like a line plot for the gains on the Exercises and the Lifts.
Do you have any suggestions for analyzes that could be performed?
The variables I’m tracking are:
Thanks!
I'd start with PCA to see the main correlations and maybe clustering. With the PCA you should be able to find nice sub-spaces, which you can plot and see, which parameters correlate the most/least. Clustering might help you identify "growth spurts". You might also try some linear regression to predict weight repetitions given the other parameters. Here I would be careful though, as the best predictor of performance will probably be the implicit 10th variable: time. You might want to tweak the regression problem to predict changes in performance given sleep, stress etc. In general, depending on what you are looking for, it might make sense to consider "change in repetitions" rather than the repetitions themselves.
I hope this helps.
