  • Summary

  • Our bodies naturally follow a roughly 24-hour cycle, called our circadian rhythm. And every cell has a rhythm. As we get older, we tend to lose muscle, making us more prone to falls and less able to live independently. Though we can't stop aging, staying active helps keep our muscles strong and our bodies healthy for longer. Prof. Karyn Esser is a specialist in how the body's natural rhythms affect muscles. Today, she guides us through the latest research and shows that it's always possible to harness the power of your muscles to enhance your quality of life. She is a professor in the Department of Physiology and Aging at the University of Florida, where she’s also the co-director of the University of Florida Older Americans Independence Center. In today's episode of ZOE Science & Nutrition, Jonathan and Karyn explore the body's internal clocks and ask: why do our muscles have their own schedule, and is there an ideal time of day to exercise? 🌱 Try our new plant based wholefood supplement - Daily 30 *Naturally high in copper which contributes to normal energy yielding metabolism and the normal function of the immune system Learn how your body responds to food 👉 zoe.com/podcast for 10% off Timecodes 00:00 Introduction 00:18 Quickfire questions 02:01 Why are muscles important, particularly as we get older? 08:45 Why we all lose strength as we age 11:07 What type of exercise do we need to maintain our muscle strength as we age? 14:55 What is a circadian clock? 19:25 Everything has a circadian rhythm 21:32 Why do our muscles work on a 24-hour cycle? 24:20 Humans are stronger in the afternoon 30:24 Is there a best time to exercise? 35:01 Can exercise before or after work help shift workers with jet lag? 37:33 Is there a difference between men and women’s responses to circadian rhythms? 41:44 What are the effects of time-restricted eating on muscle mass? 53:42 Summary Mentioned in today's episode: Defining the age-dependent and tissue-specific circadian transcriptome in male mice from Cell Reports Related studies: Timing is everything: Circadian clocks set the rhythm for vital functions in bacteria from the University of Chicago Effects of resveratrol on in vitro circadian clock gene expression in young and older human adipose-derived progenitor cells in Aging Age is associated with dampened circadian patterns of rest and activity: The Study of Muscle, Mobility and Aging (SOMMA) in medRxiv Have feedback or a topic you'd like us to cover?

Poor presenting

Useful information and interesting guests but after listening to quite a few episodes I can’t listen to this presenter any more.

Great researcher terrible interviewer

The scientist was a great communicator of their research which was fascinating. It was spoilt by bad interview skills from the presenter who asked closed questions, talked over the interviewee and was waffled taking up more air time than the scientist. Please pay for a professional presenter. I’m not sure I can listen to more without my cortisol levels rising :(

This podcaster is so rude. Constant interruptions

The woman expert was amazing and I really wanted to hear what she had to say. Sadly the presenter was just rude, constantly talking over her. Let the guests speak!
