In this episode of MASS Office Hours Live, Dr. Eric Trexler welcomes special guest Dr. Lauren Colenso-Semple, who recently defended her PhD dissertation on the influence of ovarian hormones on skeletal muscle adaptations to exercise. Trexler first discusses the importance of properly interpreting scientific evidence and understanding the hierarchy of evidence, using recent MASS articles on time-restricted eating and apple cider vinegar for weight loss as examples. The episode then transitions into a Q&A segment, covering topics such as leveraging a psychology degree to become a personal trainer, perceived muscle atrophy during specialization phases, the caloric value of dietary protein used for synthesis, the relationship between abdominal skinfold thickness and visible abs, training during pregnancy, intermittent fasting/time-restricted eating, and much more. The hosts also engage in an in-depth discussion on whether men and women should be trained differently, considering the available evidence, practical factors, and the influence of sociological aspects and client expectations on program design.

The MASS crew goes live for Office Hours every Wednesday night at 7pm eastern time. Be sure to join us for a future episode!
