DOMS - What is it? Why should I welcome it?

DOMS-DOMS-DOMS-DOMS (ouchie!)

Today's blog is brought to you by the DOMS (aka Delayed Muscle Onset Soreness) I'm currently experiencing post leg-day. 


DOMS can be a beast, leaving you feeling sore or stiff after exercise. 


And despite how it feels, it's actually a GOOD sign that your muscle is healing into a stronger state than it was in before the exercise! Huzzah for that 🙌🏽


What is it?

It's the totally normal sensation you might get after trying something new, or after pushing yourself a little harder than usual. 


It usually shows up a day or so after the exercise;  may last 2-5 days; and can affect anyone of any fitness level...yes, even instructors*!


- Spent a long day cutting back shrubs in the garden => ooh hello, achy shoulders.

- Partner made you do 101 burpees => hello achy everything!

- Tried a new Pilates class => achy abs and hips could be paying you a visit.

- Been lifting heavier weights/ doing more repetitions (😁) => yup, definitely. 


What causes it?

It's thought to be caused by the exercise causing small scale-damage (microtrauma) to the muscle fibres.   


After the unaccustomed exercise and microtrauma, the muscle quickly adapts to prevent muscle damage, and soreness, if (when) the exercise is repeated. 


This is called the "repeated bout" effect.


As a result of this effect, as well as reducing soreness next time you do the exercise, you'll also recover from any stiffness more quickly next time too!


Can you completely avoid it?

Probably not completely avoid it (unless you do absolutely nothing to put your body under novel stress), but you can reduce it.


Making sure you warm up properly and stretch a little before exercising can help. Also try increasing intensity slowly, so you get the most benefit of the repeated bout effect.


Should you completely avoid it?

Aaaahhh, now that's a better question!


No, you shouldn't completely avoid it.


Why? Because it's a sign your muscles are adapting and getting stronger which is absolutely what we want! Remember this?


Can you do anything to reduce the discomfort when you do get it?

Yes! It usually disappears after 72 hours anyway. But increasing blood flow to the muscle may help:


✅ Low intensity exercise (go for a walk or do some yoga)

✅ Massage or foam roller

✅ Light stretching 

✅ Hot bath or sauna

✅ Painkillers or anti-inflammatory tablets or gel.


Can you carry on exercising while you have DOMS?

There's some evidence that it can actually reduce the pain...and I personally find that moving again helps to reduce the stiffness.


Does the fear of DOMS put you off doing things?

Look, I know it's unpleasant. I don't like getting it either.


But reminding yourself that it's a GOOD thing and that it's just a sign you're getting stronger, can help you to feel less fear of it.

* The very first time I did PT, I was so sore and stiff after, I couldn't walk, sit, stand up, cough or laugh for about five days. It was better the second time, and better still the third...

October's Breast Cancer Awareness Month and if you haven't done it recently, please let this be the nudge you need to give them a good feel up. Here 's a link to the NHS website below showing how to perform your check and what to look for. If you're one of my gentlemen readers, please don't think this doesn't apply to you. It does. Men can still get breast cancer. And if you find something that doesn't seem right, please contact your GP as soon as possible. 80-90% of lumps are likely to be benign, but for the small percentage of those that aren't, early detection and treatment are your best chances of having successful treatment and being around to annoy friends and family for a long time. Don't skip your mammogram I know having mammograms is really uncomfortable. But this is one of the best ways to check for cancers that aren't otherwise easily spotted. So if you get invited, please go. (And don't skip your smear test either!!!) Know your risk factors 1 in 7 women will get breast cancer in their lifetime. Here are some of the risk factors: - Age : older women are more likely to get breast cancer than younger women and age is the highest risk factor. - Genetics : Breast cancer risk is higher if you have first-degree relatives who've had it (although 85% of women with a relative with breast cancer WON'T get it). - Breast density (relates to the percentage of non-fatty tissue): the risk is highest for those with the most dense tissue. You can ask your radiographer to tell you whether you have dense tissue at your mammogram. - Lifestyle factors: These include having overweight or obesity, alcohol consumption, tobacco use and insufficient physical activity. - Exposure to endocrine disrupting chemicals: These "forever" chemicals, such as pthalates and parabens, show up in makeup and toiletries. Risk doesn't normally come from one exposure to one chemical, but from prolonged exposure to many different chemicals over a long period of time. You can read more about the risks here It's worth noting that even if you get a diagnosis, it's unlikely you'll ever know if there was "one thing" that caused it. What happens if you get a diagnosis of breast cancer? I am in no way competent to comment on the treatment plan your medical team recommend for you. Everyone I know who's had breast cancer has had a different treatment plan, depending on: the stage of cancer; whether it had spread further; whether it was hormone-receptive; whether it was due to genetic mutation; and the age of the woman. I do know that for all of us, it was a really scary time. You should be given access to resources outside of the surgical and oncology team, often via a Macmillan nurse, who can answer questions on topics from your treatment and reactions, to claiming for extra benefits. They're also great if you're not sure what questions to ask. While you're in the heat of the panic, it can be difficult to think clearly about what you need to know. Using "what should I be asking that I'm not?" is super helpful. Keep moving after your diagnosis, during and after treatment The one thing I can advise you on with all confidence, is to keep moving. Exercise is safe, possible and helpful for individuals with breast cancer, throughout the treatment cycle. In fact, international guidelines say you should try to get back to your normal activities as soon as possible. Exercise can help reduce the risk of cancer coming back; and may stop stage 1 cancers from growing further; and can also reduce treatment side effects like tiredness, cognitive impairment or lympoedema. Yes, you may need to dial back your usual activities if treatment leaves you feeling exhausted. But whenever you can, please aim for 150 minutes of exercise in every week. Many forms of treatment also lead to a higher osteoporosis risk, so please also do resistance-based and/or some impact-based exercise every week. I'd also recommend paying attention to shoulder mobility. Scar tissue and "guarding" of surgery sites can reduce your range of movement a lot. Check in with your medical team to confirm if there's any specific movements you should avoid during your treatment plan, and when you'll be signed off to go back to them. One last piece of advice someone else gave me... When you tell people you have cancer, a lot of them will have an opinion on your treatment plan. Especially if they're of the "my friend cured their cancer by just eating this one thing.." type. Unless this person is an oncologist, you can safely ignore them! So, what are you still doing reading this? Go off and give yourself a fondle!
