Season Finale: Tons of New Meta-Analyses and Q&A Catch-Up
The Stronger By Science Podcast
Is This a Cumulative Effect or a Pooled Effect?
i forgot to highlight a very important detail with that. A sodium by carbonate significantly increases strength, endurance, but not maximal strength. Something important to keep in mind is there was an enormous outlier for the muscular endurance outcomes. If you see those effect sizes that were closer to point four ish, those are probably over estimates of the effect on muscular endurance.
Description: After opening the final episode of the season with a Good News segment, Greg & Eric make SBS Podcast history with the first ever prospective Feats of Strength segment. After that, Greg & Eric have an extensive Research Roundup segment in which they cover some brand new highlights from the freshly-updated Meta-Analysis Master List on StrongerByScience.com. That’s followed by a lengthy Q&A segment in which Greg & Eric try to answer as many training and nutrition questions as possible before the current season of the show comes to a close. Finally, they answer a couple of professional development questions for aspiring trainers and research interpreters To Play Them Out.
Summer break begins with the conclusion of this episode, but Greg & Eric will be back with regular episodes in the fall. In the meantime, keep an eye out for the bonus audio content that will be released throughout the summer.

To play us out: professional development questions (2:00:48).
- I am a newly certified personal trainer, and I am planning to submit applications for personal trainer positions at commercial facilities in a couple weeks. How does a new trainer know when they are "ready" to take on clients?
- I'm a first year psychology student. We recently had a class on how to read research articles, and many course materials laid out processes that would take about 5-6 hours for every single paper. What is your process for reading research? Does this change when you’re trying to get acquainted with a whole new body of literature versus evaluating a single paper on a familiar topic?
