Heart Rate Variability, Antagonist Stretching, and Chrononutrition
The Stronger By Science Podcast
Do Fibre Types Matter for Endurance?
Fibre types do matter for endurance, but it depends on what test you're using. People with more type one fibres have better strength endurance than people with more type two fibres. Hypertrophy and strength don't matter as much to a great degree for endurance or hypertrophy. But fibre distribution probably matters at least a little bit for strength development.
Greg and Eric’s plans to morph the show into a political podcast have met an untimely end, but the show must go on. In today’s episode, they discuss some totally unsubstantiated claims about the coronavirus, also known as COVID-19, followed by some impressive Feats of Strength. After that, Eric shares a research review about how the timing of your meals may alter the metabolic response to feeding, then Greg shares a research roundup about energy expenditure during times of vigorous mental effort, antagonist stretching for strength and power, and using heart rate variability to gauge your recovery from lifting. Then, Greg and Eric answer a few listener questions, share a very tentative recommendation for the “On the Rise” segment, and share a very confident recommendation for the “On the Rise” segment. To close the episode, Greg discusses some of his favorite sources of fun, informative educational content that is not fitness related, and Eric one-ups him by sharing the only source of information a person would ever need.
