Description
This is the final episode of 2020, and it’s a science-heavy episode packed full of information. After some Good News and Feats of Strength, Eric revisits a couple of previous segments and social media posts about optimal protein intakes and the potential benefits of fish oil. Greg got some new information about a paper evaluating the use of strength blocks to increase hypertrophy, so he revisits that topic as well. Finally, Greg and Eric share some new research reviews about the importance of muscle glycogen depletion for lifters and biological factors that may limit the growth of muscle fibers, followed by a sincere “thank you” to close out the year.If you’d like to receive Research Roundup emails, please sign up for our email list at https://www.strongerbyscience.com/newsletter/.

Caffeine and Health, Sex-Based Caffeine Differences, and IPF World Champion Natalie Hanson: In Episode 6, Greg and Eric discuss two recent studies about caffeine. One paper has been all over the media, with headlines suggesting that there’s no harm in drinking 25 cups of coffee per day. The other study sought to determine if men and women have the same response to a pre-exercise dose of caffeine. Greg and Eric are also joined by IPF World Champion Natalie Hanson to discuss her most recent world championship, raw vs. equipped powerlifting, and some challenges that women face in fitness and powerlifting. by The Stronger By Science Podcast
