The Midlife Cyclist – by Phil Cavell

Whether stationary cycling in your living room, or competing in the Tour de France, there’s a lot more to cycling than “push the pedals”—if you want to get good benefits and avoid injury, in any case.

This book explores the benefits of different kinds of cycling, the biomechanics of various body positions, and the physiology of different kinds of performance, and the impact these things have on everything from your joints to your heart to your telomeres.

The style is very much conversational, with science included, and a readiness to acknowledge in cases where the author is guessing or going with a hunch, rather than something being well-evidenced. This kind of honesty is always good to see, and it doesn’t detract from where the science is available and clear.

One downside for some readers will be that while Cavell does endeavour to cover sex differences in various aspects of how they relate to the anatomy and physiology (mostly: the physiology) of cycling, the book is written from a male perspective and the author clearly understands that side of things better. For other readers, of course, this will be a plus.

Bottom line: if you enjoy cycling, or you’re thinking of taking it up but it seems a bit daunting because what if you do it wrong and need a knee replacement in a few years or what if you hurt your spine or something, then this is the book to set your mind at ease, and put you on the right track.

  • Thinking about trying physiotherapy for endometriosis pain? Here’s what to expect

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Endometriosis is a condition that affects women and girls. It occurs when tissue similar to the lining of the uterus ends up in other areas of the body. These areas include the ovaries, bladder, bowel and digestive tract.

    Endometriosis will affect nearly one million Australian women and girls in their lifetime. Many high-profile Australians are affected by endometriosis including Bindi Irwin, Sophie Monk and former Yellow Wiggle, Emma Watkins.

    Symptoms of endometriosis include intense pelvic, abdominal or low back pain (that is often worse during menstruation), bladder and bowel problems, pain during sex and infertility.

    But women and girls wait an average of seven years to receive a diagnosis. Many are living with the burden of endometriosis and not receiving treatments that could improve their quality of life. This includes physiotherapy.

    How is endometriosis treated?

    No treatments cure endometriosis. Symptoms can be reduced by taking medications such as non-steriodal anti-inflammatories (ibuprofen, aspirin or naproxen) and hormonal medicines.

    Surgery is sometimes used to diagnose endometriosis, remove endometrial lesions, reduce pain and improve fertility. But these lesions can grow back.

    Whether they take medication or have surgery, many women and girls continue to experience pain and other symptoms.

    Pelvic health physiotherapy is often recommended as a non-drug management technique to manage endometriosis pain, in consultation with a gynaecologist or general practitioner.

    The goal of physiotherapy treatment depends on the symptoms but is usually to reduce and manage pain, improve ability to do activities, and ultimately improve quality of life.

    What could you expect from your first appointment?

    Physiotherapy management can differ based on the severity and location of symptoms. Prior to physical tests and treatments, your physiotherapist will comprehensively explain what is going to happen and seek your permission.

    They will ask questions to better understand your case and specific needs. These will include your age, weight, height as well as the presence, location and intensity of symptoms.

    You will also be asked about the history of your period pain, your first period, the length of your menstrual cycle, urinary and bowel symptoms, sexual function and details of any previous treatments and tests.

    They may also assess your posture and movement to see how your muscles have changed because of the related symptoms.

    During the consultation, your physio will assess you for painful areas and muscle tightness. Netpixi/Shutterstock

    They will press on your lower back and pelvic muscles to spot painful areas (trigger points) and muscle tightness.

    If you consent to a vaginal examination, the physiotherapist will use one to two gloved fingers to assess the area inside and around your vagina. They will also test your ability to coordinate, contract and relax your pelvic muscles.

    What type of treatments could you receive?

    Depending on your symptoms, your physiotherapist may use the following treatments:

    General education

    Your physiotherapist will give your details about the disease, pelvic floor anatomy, the types of treatment and how these can improve pain and other symptoms. They might teach you about the changes to the brain and nerves as a result of being in long-term pain.

    They will provide guidance to improve your ability to perform daily activities, including getting quality sleep.

    If you experience pain during sex or difficulty using tampons, they may teach you how to use vaginal dilators to improve flexibility of those muscles.

    Pelvic muscle exercises

    Pelvic muscles often contract too hard as a result of pain. Pelvic floor exercises will help you contract and relax muscles appropriately and provide an awareness of how hard muscles are contracting.

    This can be combined with machines that monitor muscle activity or vaginal pressure to provide detailed information on how the muscles are working.

    Yoga, stretching and low-impact exercises

    Yoga, stretching and low impact aerobic exercise can improve fitness, flexibility, pain and blood circulation. These have general pain-relieving properties and can be a great way to contract and relax bigger muscles affected by long-term endometriosis.

    These exercises can help you regain function and control with a gradual progression to perform daily activities with reduced pain.

    Hydrotherapy (physiotherapy in warm water)

    Performing exercises in water improves blood circulation and muscle relaxation due to the pressure and warmth of the water. Hydrotherapy allows you to perform aerobic exercise with low impact, which will reduce pain while exercising.

    However, while hydrotherapy shows positive results clinically, scientific studies to show its effectiveness studies are ongoing.

    Manual therapy

    Women frequently have small areas of muscle that are tight and painful (trigger points) inside and outside the vagina. Pain can be temporarily reduced by pressing, massaging or putting heat on the muscles.

    Physiotherapists can teach patients how to do these techniques by themselves at home.

    What does the evidence say?

    Overall, patients report positive experiences pelvic health physiotherapists treatments. In a study of 42 women, 80% of those who received manual therapy had “much improved pain”.

    In studies investigating yoga, one study showed pain was reduced in 28 patients by an average of 30 points on a 100-point pain scale. Another study showed yoga was beneficial for pain in all 15 patients.

    But while some studies show this treatment is effective, a review concluded more studies were needed and the use of physiotherapy was “underestimated and underpublicised”.

    What else do you need to know?

    If you have or suspect you have endometriosis, consult your gynaecologist or GP. They may be able to suggest a pelvic health physiotherapist to help you manage your symptoms and improve quality of life.

    As endometriosis is a chronic condition you may be entitled to five subsidised or free sessions per calendar year in clinics that accept Medicare.

    If you go to a private pelvic health physiotherapist, you won’t need a referral from a gynaecologist or GP. Physiotherapy rebates can be available to those with private health insurance.

    The Australian Physiotherapy Association has a Find a Physio section where you can search for women’s and pelvic physiotherapists. Endometriosis Australia also provides assistance and advice to women with Endometriosis.

  • The New Menopause – by Dr. Mary Claire Haver

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    The author is most famous for “The Galveston Diet”, which book is astonishingly similar in its content, chapters, format, etc to Nikki Williams’ “It’s Not You, It’s Your Hormones” which came out a few years previously but didn’t get the same marketing.

    Nonetheless, this time Dr. Haver has something new to add, and we think it’s worth a read.

    The general theme of this book is a comprehensive overview of the menopause, experientially (subjective to the person going through it) and empirically (by science), from start to finish and beyond. This book’s more about human physiology, and less about diet than the previous.

    Dr. Haver also discusses in-depth how estrogen is thought of as a sex hormone (and it is), to the point that people consider it perhaps expendable, and forget (or are simply unaware) that we have estrogen receptors throughout our bodies and estrogen is vital for maintaining many other bodily functions, including your heart, cognitive function, bone integrity, blood sugar balance, and more.

    (in case you’re wondering “why don’t men fall to bits, then?”, don’t worry, their testosterone does these things for them. Testosterone is orders of magnitude less potent than estrogen, mg for mg, so they need a lot more of it, but under good conditions they produce plenty so it’s fine)

    But, the amount of testosterone available to peri/postmenopausal women is simply not enough to do that job (and it’d also result in a transition of secondary sex characteristics, which for most people would be very unwanted), so, something else needs to be done.

    Dr. Haver also discusses in detail the benefits and risks of HRT and how to get/manage them, respectively, with the latest up-to-date research (at time of going to print; the book was published in April 2024).

    Bottom line: if you want to know what’s going on with your peri- or post-menopausal body and how it could be better (or if you want to know what’s going on with someone else approaching/experiencing menopause), then this is a top-tier book.

  • How to Fall Asleep Faster: CBT-Insomnia Treatment

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Insomnia affects a lot of people, and is even more common as we get older. Happily, therapist Emma McAdam is here with a drug-free solution that will work for most people most of the time.

    Cognitive Behavioral Therapy for Insomnia (CBTI)

    While people think of causes of insomnia as being things such as stress, anxiety, overthinking, disturbances, and so forth, these things affect sleep in the short term, but don’t directly cause chronic insomnia.

    We say “directly”, because chronic insomnia is usually the result of the brain becoming accustomed to the above, and thus accidentally training itself to not sleep.

    The remedy: cut the bad habit of staying in bed while awake. Lying in bed awake trains the brain to associate lying in bed with wakefulness (and any associated worrying, etc). In essence, we lie down, and the brain thinks “Aha, we know this one; this is the time and place for worrying, ok, let’s get to work”.

    So instead: if you’re in bed and not asleep within 15 minutes, get up and do something non-stimulating until you feel sleepy, then return to bed. This may cause some short term tiredness, but it will usually correct the chronic insomnia within a week.

  • Leek vs Scallions – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing leek to scallions, we picked the leek.

    Why?

    In terms of macros, scallions might have a point: scallions have the lower glycemic index, thanks to leek having more carbs for the same amount of fiber. That said, leek already has a low glycemic index, so this is not a big deal.

    When it comes to vitamins, leek has more of vitamins B1, B2, B3, B5, B6, B9, E, and choline, while scallions have more of vitamins A, C, and K. Noteworthily, a cup of chopped leek already provides the daily dose of vitamins A and K, and the difference in levels of vitamin C is minimal. All in all, an easy 8:3 win for leeks here, even without taking that into account.

    In the category of minerals, leek has more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and selenium, while scallions have a little more zinc.

    Both of these allium-family plants (i.e., related to garlic) have an abundance of polyphenols, especially kaempferol.

    Of course, enjoy whatever goes best with your meal, but if you’re looking for nutritional density, then leek is where it’s at.

  • Cordyceps: Friend Or Foe?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Cordyceps: friend or foe?

    Cordyceps is a famously frightening fungus. It’s the one responsible for “zombie ants” and other zombie creatures, and it’s the basis for the existential threat to humanity in the TV show The Last of Us.

    It’s a parasitic fungus that controls the central and peripheral nervous systems of its host, slowly replacing the host’s body, as well as growing distinctive spines that erupt out of the host’s body. Taking over motor functions, it compels the host to do two main things, which are to eat more food, and climb to a position that will be good to release spores from.

    Fortunately, none of that matters to humans. Cordyceps does not (unlike in the TV show) affect humans that way.

    What does Cordyceps do in humans?

    Cordyceps (in various strains) is enjoyed as a health supplement, based on a long history of use in Traditional Chinese Medicine, and nowadays it’s coming under a scientific spotlight too.

    The main health claims for it are:

    • Against inflammation
    • Against aging
    • Against cancer
    • For blood sugar management
    • For heart health
    • For exercise performance

    Sounds great! What does the science say?

    There’s a lot more science for the first three (which are all closely related to each other, and often overlapping in mechanism and effect).

    So let’s take a look:

    Against inflammation

    The science looks promising for this, but studies so far have either been in vitro (cell cultures in petri dishes), or else murine in vivo (mouse studies), for example:

    In summary: we can see that it has anti-inflammatory properties for mice and in the lab; we’d love to see the results of studies done on humans, though. Also, while it has anti-inflammatory properties, it performed less well than commonly-prescribed anti-inflammatory drugs, for example:

    ❝C. militaris can modulate airway inflammation in asthma, but it is less effective than prednisolone or montelukast.❞

    Source: Effects of the immunomodulatory agent Cordyceps militaris on airway inflammation in a mouse asthma model

    Against aging

    Because examining the anti-aging effects of a substance requires measuring lifespans and repeating the experiment, anti-aging studies do not tend to be done on humans, because they would take lifetimes to perform. To this end, it’s inconvenient, but not a criticism of Cordyceps, that studies have been either mouse studies (short lifespan, mammals like us) or fruit fly studies (very short lifespan, genetically surprisingly similar to us).

    The studies have had positive results, with typical lifespan extensions of 15–20%:

    Against cancer

    Once again, the studies here have been in vitro, or murine in vivo. They do look good though:

    In vitro (human cell cultures in a lab):

    In vivo (mouse studies):

    Summary of these is: Cordyceps quite reliably inhibits tumor growth in vitro (human cell cultures) and in vivo (mouse studies). However, trials in human cancer patients are so far conspicuous by their absence.

    For blood sugar management

    Cordyceps appears to mimic the action of insulin, without triggering insulin sensitivity. For example:

    The anti-hyperglycemic activity of the fruiting body of Cordyceps in diabetic rats

    There were some other rat/mouse studies with similar results. No studies in humans yet.

    For heart health

    Cordyceps contains adenosine. You may remember that caffeine owes part of its stimulant effect to blocking adenosine, the hormone that makes us feel sleepy. So in this way, Cordyceps partially does the opposite of what caffeine does, and may be useful against arrhythmia:

    Cardiovascular protection of Cordyceps sinensis act partially via adenosine receptors

    For exercise performance

    A small (30 elderly participants) study found that Cordyceps supplementation improved VO2 max by 7% over the course of six weeks:

    Randomized double-blind placebo-controlled clinical trial and assessment of fermentation product of Cordyceps sinensis in enhancing aerobic capacity and respiratory function of the healthy elderly volunteers

    However, another small study (22 young athletes) failed to reproduce those results:

    Cordyceps Sinensis supplementation does not improve endurance exercise performance

    In summary…

    Cordyceps almost certainly has anti-inflammation, anti-aging, and anti-cancer benefits.

    Cordyceps may have other benefits too, but the evidence is thinner on the ground for those, so far.

  • We created a VR tool to test brain function. It could one day help diagnose dementia

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    If you or a loved one have noticed changes in your memory or thinking as you’ve grown older, this could reflect typical changes that occur with ageing. In some cases though, it might suggest something more, such as the onset of dementia.

    The best thing to do if you have concerns is to make an appointment with your GP, who will probably run some tests. Assessment is important because if there is something more going on, early diagnosis can enable prompt access to the right interventions, supports and care.

    But current methods of dementia screening have limitations, and testing can be daunting for patients.

    Our research suggests virtual reality (VR) could be a useful cognitive screening tool, and mitigate some of the challenges associated with current testing methods, opening up the possibility it may one day play a role in dementia diagnosis.

    Where current testing is falling short

    If someone is worried about their memory and thinking, their GP might ask them to complete a series of quick tasks that check things like the ability to follow simple instructions, basic arithmetic, memory and orientation.

    These sorts of screening tools are really good at confirming cognitive problems that may already be very apparent. But commonly used screening tests are not always so good at detecting early and more subtle difficulties with memory and thinking, meaning such changes could be missed until they get worse.

    A clinical neuropsychological assessment is better equipped to detect early changes. This involves a comprehensive review of a patient’s personal and medical history, and detailed assessment of cognitive functions, including attention, language, memory, executive functioning, mood factors and more. However, this can be costly and the testing can take several hours.

    Testing is also somewhat removed from everyday experience, not directly tapping into activities of daily living.

    Enter virtual reality

    VR technology uses computer-generated environments to create immersive experiences that feel like real life. While VR is often used for entertainment, it has increasingly found applications in health care, including in rehabilitation and falls prevention.

    Using VR for cognitive screening is still a new area. VR-based cognitive tests generally create a scenario such as shopping at a supermarket or driving around a city to ascertain how a person would perform in these situations.

    Notably, they engage various senses and cognitive processes such as sight, sound and spatial awareness in immersive ways. All this may reveal subtle impairments which can be missed by standard methods.

    VR assessments are also often more engaging and enjoyable, potentially reducing anxiety for those who may feel uneasy in traditional testing environments, and improving compliance compared to standard assessments.

    Millions of people around the world have dementia.

    Most studies of VR-based cognitive tests have explored their capacity to pick up impairments in spatial memory (the ability to remember where something is located and how to get there), and the results have been promising.

    Given VR’s potential for assisting with diagnosis of cognitive impairment and dementia remains largely untapped, our team developed an online computerised game (referred to as semi-immersive VR) to see how well a person can remember, recall and complete everyday tasks. In our VR game, which lasts about 20 minutes, the user role plays a waiter in a cafe and receives a score on their performance.

    To assess its potential, we enlisted more than 140 people to play the game and provide feedback. The results of this research are published across three recent papers.

    Testing our VR tool

    In our most recently published study, we wanted to verify the accuracy and sensitivity of our VR game to assess cognitive abilities.

    We compared our test to an existing screening tool (called the TICS-M) in more than 130 adults. We found our VR task was able to capture meaningful aspects of cognitive function, including recalling food items and spatial memory.

    We also found younger adults performed better in the game than older adults, which echoes the pattern commonly seen in regular memory tests.

    Adults of a range of ages tried our computerised game.

    In a separate study, we followed ten adults aged over 65 while they completed the game, and interviewed them afterwards. We wanted to understand how this group – who the tool would target – perceived the task.

    These seniors told us they found the game user-friendly and believed it was a promising tool for screening memory. They described the game as engaging and immersive, expressing enthusiasm to continue playing. They didn’t find the task created anxiety.

    For a third study, we spoke to seven health-care professionals about the tool. Overall they gave positive feedback, and noted its dynamic approach to age-old diagnostic challenges.

    However, they did flag some concerns and potential barriers to implementing this sort of tool. These included resource constraints in clinical practice (such as time and space to carry out the assessment) and whether it would be accessible for people with limited technological skills. There was also some scepticism about whether the tool would be an accurate method to assist with dementia diagnosis.

    While our initial research suggests this tool could be a promising way to assess cognitive performance, this is not the same as diagnosing dementia. To improve the test’s ability to accurately detect those who likely have dementia, we’ll need to make it more specific for that purpose, and carry out further research to validate its effectiveness.

    We’ll be conducting more testing of the game soon. Anyone interested in giving it a go to help with our research can register on our team’s website.The Conversation
