Summary

Dr. Cheri Mah returns to the podcast today to explore a few different topics including how circadian rhythms shape athletic performance. She notes that these 24-hour cycles regulate sleep, hormones, and core temperature, with peak physical capacity often occurring between 4-8 pm—when many world records are set. Dr. Mah also discusses chronotypes, showing how tailoring training to one’s natural rhythm can enhance results. She reveals research on circadian disruption in sports, notably ho...

Hi there, it's Matt here and welcome back to the show. After an incredible first episode,

0:09.0

I have backed by popular audience demand Dr Sherry Marr to dive deeper into her work on sleep and athlete performance.

0:18.0

Today, we're going to focus on circadian rhythms, travel, and their impact

0:24.5

on athletic performance. As you may remember, Dr. Marr is a renowned sleep scientist at Stanford

0:30.5

University and a pioneer in the fields of sleep, sports, and athletic performance. She's a highly sought-after advisor to some of the

0:40.1

world's sporting superstars and professional teams. Today, we'll explore her findings and discuss

0:47.4

practical ways to optimize sleep for peak performance. So welcome back, Dr. Marr, to the show.

0:57.5

Much requested.

0:59.0

We've got lots to explore.

1:02.0

Perhaps the first question to just go straight in

1:06.3

is coming back to this notion of circadian rhythms and circadian alignment that I mentioned in

1:14.1

the introduction, tell us what circadian rhythms are perhaps at the top. And even though we've

1:21.2

discussed that on this show before, some folks may not really have a good concept. And then once we

1:26.1

understand what they are, why are they so

1:28.7

important, especially for athletes? Sure. Well, excited to be back. Thank you for having me on again,

1:35.2

and I'm excited to dive a bit more into circadian rhythms and performance impact. So our body clock,

1:42.1

or our circadian rhythms, it's a natural 24-hour cycle that governs many

1:48.1

functions from our sleep patterns to our core temperature to hormonal regulation and more.

1:55.2

And maintaining that regularity is important that our bodies really crave to have the regularity to function

2:02.6

well and reliably throughout the day. So when I think about in the context of athletes who are

2:07.3

trying to be at their peak performance, consistency is key. And you want to leverage specific

2:14.0

times of the day as an athlete for optimizing your training and your performance.
