It would be rhetorical to say: that your body is special. And you would only want the best to be guiding you through your health and well-being safely. And yet, one can still be suggestible- picking up dodgy anecdotal tips from ‘that guy’ on the lat-pull-down machine.
I have personally experienced the exercise benefits, being safely loaded, and moving with confidence with one of my colleagues. Leaving my body and surrendering to an expert has given myself a deeper appreciation of the importance of finding an expert in human movement.
I have always been on the other side to what I have been accustomed too- and as bias as it sounds: my colleagues here at iNform health really know how to manage and care for their clients.
Here are three reasons why you should be exercising with an expert.
1. Your tissues need time to adapt to load.
Your tissues, all the way down to the extracellular matrix- are for ever adapting to stressors and making proteins. Prescribing appropriate load- will ensure ones tissues will safely adapt; which will add a host of benefits to ones neuromuscular system. Reduced risk of tendonopathies, appropriate motor learning and myonuclei growth (muscle hypertrophy). On the contrary, excessive loading that exceeds the capacity of the neuromuscular system can induce the contra effects to the aforementioned. Tendon pathology, disorganised motor learning due to inappropriate load and systemic inflammation (abnormal prostaglandin levels) due to poor tissue healing.
2. Assessing the capacity of the neuromuscular system before undertaking load is paramount- and if neglected, your ‘health professional’ is going in blind.
If there is a muscle inhibition due to de-conditioned tissues, or a previous pathology that was poorly rehabilitated, would you feel safe to be loaded? Or if you were unable to co-contract your gluteus maximums, or have adequate lumbo-pelvic control? And yet, you may still be subjected to axial loading in your first session…! A thorough musculoskeletal assessment can identify any red flags and give your health professional valuable subjective/objective information to prescribe appropriate exercise correctives. This will then ensure more complex movements are performed safely.
3. Co-care is so important in addressing the whole individual.
Here at iNform, our clients are closely monitored by a wonderful internal/external team of allied health professionals; ranging from: GP’s, physio’s, osteo’s, chiros, pod’s and psychologist (without exhausting). All working and communicating together for the greater good of your physical and mental health. Co-care leads to better clinical outcomes, a proper working diagnosis, and the right form of treatments that benefit you the individual.
So, next time you are wanting to move with confidence. Be interrogative with your research. Find an evidence based approach that doesn’t involve a lecture from ‘that guy’ wearing a weight belt with a skimpy muscle singlet (stereotyping much?).

Cardiovascular risk factors are well known to increase one’s risk of a stroke, and or vascular dementia. There is a lot one can do to prevent cardiovascular disease (CVD), stroke and maintain great heart health. I am sure you would like to know the evidence based risk factors for the aforementioned?
What are the risk factors for CVD and stroke?
In a recent paper published in the journal JAMA: Williamson et al used modifiable, evidence based risk factors in young adults (18-40 years) whom without any known evidence of cerebrovascular disease. To investigate using magnetic resonance imaging (MRI), if subjects brains were showing early signs of cerebrovascular disease. Cardiovascular risk factors that were measured ranged from: body mass index <25, cardiovascular fitness, alcohol consumption >8 drinks/week, non-smoker >6 months, blood pressure >130/80 mm Hg, cholesterol and fasting glucose.
What were the findings?
Each of the aforementioned risk factors were assigned a rating of 1, in a 8 point scale (8 separate risk factors). Scoring higher was inferred as having a low risk of cerebrovascular disease. Subjects that had more clinical risk factors (< 2 points), did show some early signs of cerebrovascular disease on MRI (1). Researchers found white matter hyperintensities, which are lesions contributing to demyelination of important neural fiber tracts in the central nervous system in subjects with <2 points. What does this mean? less connectivity = slower brain processes (executive functioning, working memory et cetera). For 18-40 year olds showing clinical signs this early- intervening with evidence based modalities would benefit the individual greatly.
So, how do I reduce the risk of developing cerebrovascular disease?
First of all- DON’T PANIC! although published in a reputable journal, the paper was a preliminary study, with further longitudinal studies required with a larger sample that is ethnically diverse. HOWEVER, all of the mentioned cardiovascular risk factors can be modifiable. The following 5 key points will get you in the right direction to good heart health!
Aerobic exercise: following the physical activity guidelines with 150 minutes of moderate aerobic activity per week. If you are sedentary >8 hours per day: aim for 75 minutes of accumulated physical activity per day.
High intensity interval training: 1-2 sessions per week, following an evidence based protocol, with guidance from your exercise physiologist and GP. Three 7-10 second sprints with a balanced work to rest ratio is suffice according to the literature.
Strength Training: 2-3 strength training sessions a week with accordance of the Exercise Sport Science Australia guidelines, with guidance from an accredited professional.
Sleep: although I am not a sleep physiologist, there is ample evidence relating poor sleep <6 hours/per night with CVD and insulin resistance. Sleeping 7-8 hours per night with optimal sleep hygiene is recommended by experts.
Nutrition: again, without being a nutritional expert: following evidence based guidelines (CSIRO), will ensure targeted bloods are met and there is less plaque build-up (atherosclerosis).
So there you go peeps! So many preventative ways you can keep your brain tissue myelinated! And your cardiovascular system in good “heart health”.

I often get asked how does the brain deal with pain? The brain is a highly complex organ so lets not think of the brain regions as an entity; more like a highway of networks communicating. To understand how the brain makes pain, I will use the analogy of networks like a map. You may come to have some gratitude towards your brain, as your brain is only doing it’s absolute best to protect you.
So how does your brain deal with pain? Here’s an everyday analogy
Keeping to the network analogy: lets say you are meeting a friend for a coffee at a new unbeknownst location. You lock in the coordinates in your mobile app, and away you go. You start briskly walking and come across a busy pedestrian crossing. Of course you wait until the green logo flashes for you to safely cross.
As you continue to walk a cyclist rings their bell to notify you of their passing. The initial noise was alarming, which caught you by surprise. However the cyclist speeds on by, and you are back to absorbing the beautiful sunshine.
Further up the road you notice a branch impeding the footpath from the previous days storm. You decide to live a little, and jump over the branch thanking your exercise physiologist for the strong bones. Your heart rate settles back down, and your mobile app notifies you that you are five minutes from your destination.
As you see the coffee shop in the distance you close down the app taking your eyes briefly off the footpath to put your mobile phone away. Within a matter of milliseconds a car pulls out of the driveway while your head is still down. You put on your own breaks, by contracting your muscles with great force to prevent walking into the red jeep.
The driver gives you a wave in courtesy, and takes off. Still feeling a little startled, a memory comes up of your one and only bike accident. Five years ago with a red sedan, while you were training for your maiden triathlon. You consciously rub your right shoulder. Your friend meets you with a warm smile and hug. You both sit down, and your friend notices that you look a little ‘stiff’.
Breaking down the perceive threats so that we can understand how your brain deals with pain
The following analogy contains many contexts that I am going to break down with you, and most importantly reduce the threats. In my analogy I constructed a few events during the walk to the coffee shop that all have contextual meanings that the brain must process. Most are safe, with a couple having more meaning, can you guess which ones?
The pedestrian crossing is a safe means to cross the road. Although the crossing is busy with traffic. The brain likes the safety of the green light. What about the speeding cyclist? Although the cyclist bell would have been initially startling- fast acting areas in your brainstem enable you to respond quickly, the cyclist was also being courteous, while speeding off, which your brain processes the comforting visual information of safety.
What about the branch on the footpath? Haven’t you been strength training with your exercise physiologist? and feeling confident and strong? The quick jump activates the fight and flight system to release adrenaline to contract your muscles quickly, the brain enjoys these types of acute stress.
Now, how about the red jeep pulling out in front of you without any warning? Now here is an acute threat. However there are some added contexts to consider. The colour of the jeep is significant (remember the red sedan?), along with the colour red meaning: stop, hot and danger! And what about the significance? Weren’t you training for your first triathlon before being knocked off- with a subsequent right shoulder injury?
That is a pretty significant event that your brain ought to remember with great detail to protect you. However, the accident happened five years ago. Still, every time you see a red car, you notice that you hold onto your breath.
Lastly, your friend used the word “stiff” to describe your seated posture. What comes to mind when you think of stiff? Stiff can be in reference to your muscles tightening up reducing mobility, and maybe activating that neat fight and flight response again. But do you need it this time?
Can you see how everyday events can trigger the networks in the brain to communicate on: sound, vision, memory, colour and muscle tone? And how the significance of the event, even though it happened five years ago, can still alarm the brain to protect you?

Can we use Strength Training for depression?
Any keen gym goer would have heard of the film “Pumping Iron” – and the subsequent revolution of Bodybuilding. Besides from being built like Hercules and having a positive-B sample, Strength Training has a lot of wonderful benefits for men and women. But what about Strength Training for depression?
Well, a recent meta-analysis published in the journal: JAMA Psychiatry may have just eluded some neat findings for Strength Training as an adjunct for reducing depression. The meta-analysis included: 33 clinical trials, with 1,877 participants. Gordon and colleagues found: “resistance exercise training was associated with a significant reduction in depressive symptoms.”
Promising news. However, there are limitations to consider… “total volume of resistance exercise training, health status and strength improvements were not associated with an antidepressant effect”.
So what could be some potential hypothesis that are contributing to the antidepressant effects experienced by the participants?
Filling in the gaps for using Strength Training for depression
First and foremost – we are born to move! When are ancestors became bipedal – moving to find food, water and shelter was essential.
And what happens when there is an unexpected reward? Dopamine is released, which causes a surge (reward dependent) of this wonderful catecholamine increasing the likelihood that the behaviour will be repeated – such as moving to find more resources, or more dumbbells!
Secondly, Strength Training has noteworthy benefits in the release of particular growth hormones and hypertrophic increases in muscle tissue. It would be plausible that an increase in testosterone, along with bigger muscles, would most definitely increase motor behaviour (going to the gym), along with libido (I will leave you with your own imagination). Which would equate to more energy being utilized, while also affecting higher cognitive regions in the frontal lobe improving: attention, motivation and reduced impulsiveness. The same areas of the brain that are inhibited by depression!
Lastly, although are ancestors missed out on dubstep, listening to music whilst exercising greatly activates many brain regions, along with an endogenous release of natural opioids that increase euphoria. I can see Hippocrates prescribing dubstep for his melancholic patients…
So hopefully I’ve filled in some missing gaps in the aforementioned meta-analysis that would be difficult to quantify.
Key take home points when using Strength Training for depression:
- Work with an accredited Exercise Physiologist/Scientist – to move with confidence. While also being guided about specific exercise prescription for your current goals, or medical condition.
- Make a sweet as music-playlist to increase baseline mood when Strength Training. Creating your own playlist will likely increase adherence to Strength Training along with enjoyment and motivation.
- Lastly, always consult your GP – if you are currently inactive, and wanting to increase your physical activity levels. The team at iNform can assist you from there onwards.

Exercise to improve mental health and well-being comes across as rhetorical. And to throw a pun in: it’s a no-brainer!
A recent study published in the American Journal of Psychiatry has found exercise can reduce depression globally by as much as 15%! Now, 15% does-not sound like much. However, with data collected worldwide – with a population cohort of 266,939, 15% starts to sound pretty darn good; or for you statistical nerds out there: a neat reliable confidence interval.
Take me through the interrogatives and detail James!
The authors didn’t elude how much physical activity is required to elicit an anti-depressant effect. If you read my last blog, you would know what the recommended physical activity guidelines are. What is more important, is the neuroprotective effect(s) exercise has. And from interpreting the paper: participants were followed longitudinally over six to eight years, which correlates nicely that exercise has a protective buffer to continuous stress. Depression is highly complex; interacting with genes the immune system and the environment. However the solution is simple: all one needs to do is-to huff and puff a little bit – from day to day, to statistically decrease depression!
Tips for using exercise to improve mental health:
Exercise needs to be enjoyable!
- A brisk walk on the beach..
- Kicking the footy with the lads/lasses..
- Or, hitting the gym for a workout or group-fitness class..
The list goes on..
When you choose the exercise that resonates with yourself the likelihood for adherence is higher. Enjoyable activity results in more brain regions becoming active – and neuromodulators releasing sweet beneficial chemicals, affecting your mood, motivation – and thus well-being!
So what are you waiting for? – Lets get moving together!
