Small sample size is one of the main drivers of bias for statistical significance in sport and exercise medicine

This manuscript was submitted as a letter to the editor to the Journal of Science and Medicine in Sport but was rejected "because it does not reach sufficient impact for JSAMS". So, as it will never be published in a scientifc journal, I guess it can't be called a "preprint" anymore but is now an "unpublished manuscript" (although this also seems inaccurate as it is published on ResearchGate and PsyArxiv). Maybe some readers who want to learn more about sample size, effect size, and p-values will still find it interesting.
