Heather O'NeillGUEST
Um, increase repetitions and intensity as the body adapts.
speaker_1NARRATOR
Today's episode features audio from the Expert Insights Physical Activity Webinar, part of the Living Well with MS Webinar Series.
speaker_1NARRATOR
Overcoming MS facilitator Heather O'Neill and trainee facilitator Lindsey Housden explain physical activity and exercise tips for people living with MS.
Heather O'NeillGUEST
Welcome back to Living Well with MS webinar series.
Heather O'NeillGUEST
We're gonna be discussing a topic of physical activity and MS.
Heather O'NeillGUEST
So my name is Heather O'Neill.
Heather O'NeillGUEST
I'm an Overcoming MS facilitator and clinical social worker joining you from Denver, Colorado, in the United States.

Just a quick note to say that all opinions are those of the guest and do not constitute medical advice.
Matt BennettHOST
We then look at a machine learning study asking whether your heartbeat alone, processed through a random forest classifier, can tell you what stage of sleep you're in.
Matt BennettHOST
And we close with a six month study following patients with chronic obstructive pulmonary disease through a physical activity coaching program, where the most sensitive autonomic signal comes not from standard HRV metrics, but from point-to-rate plot geometry.
Matt BennettHOST
Seven studies, seven angles, all of them pointing toward the same truth, The autonomic nervous system is the body's central integrating network, and HRV gives us one of the best windows we have into how it's functioning in real time.
Matt BennettHOST
One more thing before we start.

Matt BennettHOST
The final study today is the one I've been building toward, and I want to give it the time it deserves.
Matt BennettHOST
This comes from PLOS One, published in August 2026 by Fian Hermans and Helene DeMeyer at Ghent University Hospital, along with a large multidisciplinary team, including pulmonologists, physiotherapists, and respiratory scientists.
Matt BennettHOST
The title is The Relation Between Physical Activity and Cardiac Autonomic Dysfunction in Patients with Chronic Obstructive Pulmonary Disease.
Matt BennettHOST
Let me start with the population context, because it shapes everything that follows.
Bonnie HarrisonCORRESPONDENT
It's a large review.
Bonnie HarrisonCORRESPONDENT
Leisure time physical activity like sport, dancing, going to the gym, that was linked with a 24% lower risk of dementia.
Bonnie HarrisonCORRESPONDENT
Housework reduced risk by 15%.
Bonnie HarrisonCORRESPONDENT
Oh.
Bonnie HarrisonCORRESPONDENT
occupational physical activity, on the other hand, was linked to a 20% increased risk of dementia.
Jim MoraHOST
You mean walking to work or cycling to work or whatever?
Bonnie HarrisonCORRESPONDENT
Yeah.
Bonnie HarrisonCORRESPONDENT
That's linked with a 41% lower risk of dementia.
Norman SwanHOST
And when you're talking...
Norman SwanHOST
I mean, this is expanding the story, but we'll come back to steps in a moment, is another issue is you're following the physical activity guidelines.
Norman SwanHOST
A lot of debate around what's moderate exercise, what's vigorous exercise-
Preeya AlexanderHOST
Yes
Preeya AlexanderHOST
[laughs]
Norman SwanHOST
... of the detail about this study.
Norman SwanHOST
Let's talk to the, the lead author on this study, who's Professor Emmanuel Stamatakis, who's professor of physical activity, lifestyle and population health at Monash University.
Norman SwanHOST
Been on The Health Report many times before when he was at the George Institute.
Cameron SaundersGUEST
There's lots of things people can do to keep active.
Greg FootHOST
Well, the recently updated UK Chief Medical Officer's Physical Activity guidelines do explicitly say that, "Physical activity does not need to take place in long or structured sessions to have a positive impact.
Greg FootHOST
Walking to the shops, wheeling, taking the stairs, dancing, gardening, active play, and household tasks can all contribute towards improving health when carried out regularly."
Cameron SaundersGUEST
I think the key thing here is what we're seeing is a growth of strength training because as you get older, it's about maintaining your muscle mass, it's maintaining your stability, your bone density.
Nele von HorstenHOST
Interview with Professor Doctor Doctor Philipp Zimmer.
Nele von HorstenHOST
Exercise and multiple sclerosis are closely connected, not only when it comes to strength, endurance, and mobility, but also through the effects physical activity can have on the immune system.
Nele von HorstenHOST
This episode is an English adaption of my original German interview with Professor Doctor Doctor Philipp Zimmer, first published on 14th August 2023.
Nele von HorstenHOST
You can find the original German interview in the show notes or on the blog article.
Nele von HorstenHOST
In our conversation, Professor Zimmer explains what exercise immunology can teach us about multiple sclerosis, why aerobic exercise is particularly interesting from an immunological perspective, what role strength and balance training play, and why people with MS can benefit from finding a form of exercise that genuinely fits their abilities and everyday life.
Nele von HorstenHOST
A small spoiler before we begin.
Nele von HorstenHOST
Regular physical activity is well worth integrating into everyday life.
Nele von HorstenHOST
Depending on your individual situation, exercise that challenges you enough to raise your heart rate and make you sweat can contribute to fitness, symptom management, and potentially beneficial adaptations of the immune system.
Tara-Leigh McHughGUEST
Sure, thank you.
Tara-Leigh McHughGUEST
Yeah, my name is Tara Lee, as you just said, and I'm a professor and a Canada Research Chair in Sport and Physical Activity in the Faculty of Kinesiology at the University of Calgary.
Tara-Leigh McHughGUEST
And I'm sure I will be talking about the most recent study that we published today, but my research is broadly focused on understanding how women's experiences of their bodies shape their participation in sport and physical activity.
Tara-Leigh McHughGUEST
So their experiences more broadly in terms of body image, their menstrual cycle experiences, the experiences of pregnancy and postpartum, which we're going to talk a bit more about today.
Tara-Leigh McHughGUEST
But then also their experiences of perimenopause and menopause.
Tara-Leigh McHughGUEST
So ultimately, women's experiences of their bodies and how that shapes their participation in sport and physical activity.
Erin AyalaHOST
It's such an exciting time in our field to be able to have that, right? So then I came across the article, which we'll start to get into, is you've been able to center your research on something that a lot of sport organizations have largely ignored.
Erin AyalaHOST
In this case, it's the experience of mother coaches in high performance sport.
Margie DavenportGUEST
I teach one course a year.
Margie DavenportGUEST
And I have this brilliant team of young up and coming and really actually some of them are quite established now researchers covering everything from, you know, looking at really complex pregnancies, looking at congenital heart disease in pregnancy and twin pregnancies and what role physical activity might have in supporting their health to our elite level athletes working or working competing at the Olympics and Paralympics while they are mothers as well.
Margie DavenportGUEST
And so it really spans the gamut from preconception right through postpartum, from somebody who is traditionally told not to exercise at all during pregnancy, right up to people who are told that they're exercising too much during pregnancy.
Melissa DessaullesHOST
And so if I think really quickly about just if I could capture some of the main things that I hear in pregnancy.
Melissa DessaullesHOST
Okay.
Margie DavenportGUEST
Mm hmm.
Margie DavenportGUEST
So as part of the 2019 Canadian guideline for physical activity throughout pregnancy, we did a survey of all available literature at that particular point in time, we synthesized it into 12 systematic reviews and meta analyses.
Margie DavenportGUEST
So It took three years to get to the point to make the recommendation of engaging in at least 150 minutes per week of moderate intensity physical activity spread over three or more days of the week was associated with really profound clinically meaningful health benefits.
DunniHOST
You can just pace up and down.
DunniHOST
Some people just do a very quick physical activity some people go for a hit so high intensity interval training activities which kind of mixes some cardio and keeps your heart pumping that is what you want you want to keep your heart pumping you want to feel alive and probably break a sweat as well so these are very practical things that you can do in your more minimum morning routine Now, very importantly, think about how your day is going to go.
DunniHOST
In all my previous episodes of this show, I always talk about how your activity for the day is usually not planned on the day.
DunniHOST
It's better it's planned now.
DunniHOST
And I have to confess that when the children were younger, I had never, ever been to a gym in my life.
DunniHOST
So I was exercising.
DunniHOST
I was doing a lot of physical activity, but I wasn't going to the gym.
DunniHOST
So I now got to a point in my life where I involved my children in my physical activity.
Gary ScheinerGUEST
What's still left from the last dose we gave? And make sure we're not stacking on top of that.
Gary ScheinerGUEST
You know, we also have to think about the physical activity that's coming up soon and whether we need to adjust the dose for that.
Jennifer SmithHOST
Or that we've done, right?
Gary ScheinerGUEST
Or that we've done.
12 MINS LATER
Gary ScheinerGUEST
And if we don't account for that, we can get in serious trouble because we're stacking insulins and we end up going quite low if we don't consider and factor out the insulin
Gary ScheinerNARRATOR
that's still on board.
Gary ScheinerGUEST
Then the fifth part of the dose calculation is physical activity.
Gary ScheinerGUEST
As you know, physical activity makes the body more sensitive to insulin.
