| 0:00.0 | So finally, exercise scientists were like, hey, you know, athletes have inflammation. |
| 0:15.0 | What if they're also having a HEPFIN response? |
| 0:18.0 | And so over the last, you know, I would say 10 years, this is, this has been |
| 0:22.6 | research. And what we know is that with exercise, immediately after about exercise, so high |
| 0:29.6 | intensity and or high intensity exercise that involves chronic, repetitive foot striking, you're |
| 0:35.6 | going to see an immediate increase in something known as Interleukin 6. |
| 0:40.3 | And it's that interleukin 6 that spikes or stimulates that release of Hepsidon from the liver. Hello and welcome to Sigma Nutrition Radio. As ever, I am your host, Danny Lennon, |
| 1:09.0 | and today we're at episode 240 of the podcast. |
| 1:14.7 | Over the next couple of weeks, I'm going to be making a pretty big announcement or something |
| 1:19.0 | I'm certainly very excited by that I think will be of relevance to a lot of you, or hopefully |
| 1:26.1 | at least should be quite a big bit of news, and I'm very |
| 1:29.2 | excited to talk about that. It's going to be at some stage over the next couple of weeks, |
| 1:33.1 | and the best way to keep up to date with that, if you're not listening to every episode, is just |
| 1:38.5 | to be on the email list for the Sigma Synopsis. So if you're unaware, every week I send out a short brief email |
| 1:47.0 | called the Sigma Synopsis, which is basically a list of different pieces of content that I think |
| 1:53.7 | you might find useful. So not only will it give a very short breakdown of the latest podcast episode, |
| 1:58.4 | but it will be other content from around the internet that |
| 2:01.1 | I think you might like. So it'll be a recommended article of the week, a video, some sort of |
| 2:06.2 | podcast material, maybe a research paper, just something in a short list I think will be |
| 2:12.3 | particularly interesting. And you can kind of look through. It'll take you like 10 seconds to |
| 2:16.5 | scan through the email. You pick out something that's interesting to you. You leave everything else. And it also has a little section that will keep you up to date with the latest news and announcements. |
| 2:25.3 | And so over the next couple of weeks, I'm going to be making announcement to the email list first and foremost. |
