Natalie Dau is a Singapore-based 10-time ultramarathon winner, crossed the finish line at The Westin Singapore on 5 June, marking the completion of her incredible Project 1000. Over the course of 12 days, Natalie ran an astonishing 1000 km, beginning the journey in Hat Yai, Thailand, on 25 May, traversing the entire length of Malaysia, and concluding the journey in Singapore. Covering a distance equivalent to approximately 2 marathons (42.2 km x 2) per day, the run concluded on Global Running Day, 5 June. Starting at 4 am on the final day, local runners in Singapore were invited to join in at various join points, seeing hundreds of individuals participate in running with Natalie and supporting her through to the finish line. Hundreds were gathered at The Westin Singapore to celebrate her historic achievement, with distinguished guests including MP Poh Li San and Mr. Ong Eng Huat of the Singapore Book of Records.

Finishline – Natalie

Natalie was recognized at the finish line by the Singapore Book of Records for the “Fastest 1000 km Thailand-Singapore Ultramarathon,” and her Guinness World Record title for the “Fastest Crossing of Peninsular Malaysia on Foot” is now verified.

Throughout the 12-day run, Natalie battled extreme heat, lack of sleep, dangerous road conditions, and a variety of other factors including wild dog chases. She was operating on just a few hours of sleep each night, starting the mornings shortly after midnight to maximize running during the cooler hours of the day. The temperatures were so high that her shoes melted on the pavement, and she went through 4 pairs of shoes on the trip.

Despite the extreme conditions and struggles with a hip injury and a urinary tract infection, she was determined to continue the journey and insists that giving up was never an option. “This project was about community, teamwork, and perseverance, and so many people were counting on me. I couldn’t let them down. I never considered stopping, and am so grateful to everyone who supported me and believed in me.” shared Natalie.

Natalie and Team.

Alongside the challenging factors, Natalie and her team were touched by numerous beautiful moments as they passed through local communities in Thailand and Malaysia, encountering warmth and kindness with people rushing to bring her water on the roadside, or giving a friendly wave of support. She also visited Hat Yai University and several local schools along the way, speaking with children about her experience and encouraging them to believe in themselves and pursue their dreams.

A cause closest to her heart, with Project 1000, Natalie is raising funds to support underprivileged women and girls, and bringing awareness to the gender gap in exercise and the importance of physical movement for mental health and overall wellbeing. Funds raised through Project 1000 are contributed to GRLS, a global charity and part of Women Win, which works to elevate women and girls around the world through sport and exercise.

Natalie and MP Poh Li San

While challenging herself to push to new limits, at 52 years, Natalie hopes that her example may help others to feel confident, dream bigger, and resist self-limiting beliefs and societal expectations. “No matter what your goal is, it doesn’t have to be running or sport, everyone should feel that they can do something and believe in themselves,” shared Natalie.

Differences between men and women

Understanding the differences between men and women in long distance running

It’s a fact. Men and women simply have different morphology. Most runners will have a training plan to clock in the distance in order to achieve their goal of be it a 5km or an ultra marathon.  While we are determined to cross the finish line with our personal best time, it would help to get to know your body better so you can reach the maximum potential of your given anatomy. In order to optimise your training and improve your performance, I’ve compiled a few differences that will create a better understanding of the differences between men and women.

Physiological gender differences & implications for training and performance

Before boys and girls hit puberty, their body structures are similar in terms of body weight, height, length of their legs and upper-arm circumference. During puberty, development occurs and boys will start to develop larger shoulders while girls start to develop larger and wider hips. Due to the smaller shoulder size of women, this poses a disadvantage for women to develop upper-body strength, limiting their body strength on the upper-body in comparison to men throughout adulthood. Women’s narrow shoulders compared to men’sare also generally shorter and women are naturally born with larger pelvis width-to-height ratio and shoulder-to-hip ratio than men.

“We some times hear the term pear-shaped being used to describe a woman’s shape, but the basic truth thata woman has wider hipsis specifically for the purpose of child bearing. Notice that most professional female runners tend to have smaller and narrower hips, so it’s their natural born physique that also aids them towards excelling in distance running”.

The Q Angle (or Quadriceps Angle)

The anatomical and biomechanical features are disparate between men and women. Women have a larger pelvis because they are designed to carry the child. This larger pelvis combined to a shorter femur lead to a different Q angle at which the quadriceps muscle – from the pointiest position of the pelvis, scientifically known as the Anterior Superior Iliac Spine – meets the kneecap (or patella), compared to the line connecting the ligament attaching the patella to the shin. The angle between these two lines forms the Q angle.

Males have a Q angle between 8 and 15 degrees while females have a Q angle between 12 and 19 degrees.

SOURCE:PHYSIOPEDIA,Q ANGLE

How does this difference influence the running?

Women, as they have a broader angle, are more subjected to Anterior Cruciate Ligament (ACL) injuries while exerting themselves. The Q-angle dissimilarity refers to a difference of knee alignment as well. In short, men are anatomically better designed than women for running. The space for ACL movement is more limited by women than in men, putting the ACL in a critical position as it can easily get pinched and lead to rupture of the ligament, especially while stretching or twisting. However, when you practise how to train properly, you will lower the risks of getting injuredmale or female.

In summary,

  • A larger Q-angle puts women at a mechanical disadvantage when running.
  • Wider hips and a large Q-angle put the femur at an angle when the foot is on the ground.
  • Elite female runnershave narrower hips, which closely resemble male runners. Research has also shown that the hip width of very good female runners is similar to that of both athletic and even non-athletic males.
  • Women’s anatomy also affects their stride mechanics. Research has shown that female runners take shorter strides than male runners when running at the same speed. Although it’s interesting that the combination of stride rate and stride length differs between female and male runners, it’s not completely clear why women take shorter strides.
  • Obvious reason is that women are generally shorter than men and have shorter legs, hence the shorter strides. (misconception among runners)
  • Research has also shown that taller runners don’t take longer strides than shorter runners. Stride length is more a product of hip extension and how much force your muscles produce as you push off the ground.
  • Therefore, something else must cause female runners to take shorter strides than male runners when running at the same speed

Differences in body weight and body composition

Muscular differences

Muscle mass is on average 35% of the total mass of a man against 28% in women. Moreover, women have more “fat” than men. The fat of a woman averaged 20% against 13% in a man.

  • Women have a smaller muscle than men
  • Women can’t produce much muscle as much as men
  • Men are able to sprint faster than women

Knowing that muscle activity is the cause of energy expenditure during exercise, and the woman has less ability to produce energy and therefore less strength and endurance.

Cardio muscular distinctions

The heart

The heart is a cardio muscular muscle that enables oxygen through blood stream to be pumped to your muscles.The female heart is smaller. While it weighs 118 grams on average in women, men’s hearts weighin at about 178 grams on average. Training improves the heart skills in both women and men. This enhancement is however limited in women.

Maximum Heart Rate is the maximum number of beats the heart can achieve in the space of a minute. This value is unique to each individual and it also changes with age and gender.

The Maximum Heart Rate is thus higher in women than in men. On average, a woman will reach 174 beats per minute against 169 beats per minute. Women’s hearts beat faster because the volume of blood ejected by the heart is lower than men’s.

However, a smaller heart doesn’t mean men are better at running marathon. Even though you first impressions turn into men’s advantages, women are still in the run!

 

VO2max: maximal oxygen consumption

Femaleshave less blood than males. This could be explained first by the period women experience every month, but that isn’t the only factor. The blood plays an important role while running. Indeed, the vital oxygen you need to make your muscles work is transported through blood.

VO2max is the maximum capacity to store, transport and use oxygen during aerobic exercise. In other words, this is the maximum volume of oxygen consumed during exercise. Your muscles and oxygen are necessary to produce the required energy for training. The more your VO2 max is, the more your body is able to use oxygen to produce energy.

The VO2max on average for male is45-50 ml/min/kg and 35-40 ml /min/kg for women.

Men have an average of 13.6 to 17.5 grams of haemoglobin per decalitre in their blood. Women have 12.0 to 15.5 grams per decalitre.

Women therefore have less capacity to store and transport oxygen, a difference that translates both during tests of strength or resistance during endurance events.

 A more advantageous metabolism in women

Carbohydrate (or glucose) is stored as glycogen in the muscles and liver. These stores represent the prime source of energy but they are limited. Indeed, the muscles can store about 400 grams of glycogen and the liver 100 grams.

After running out of this energy, a runners’bodywill seek another source of energy through the fat. You store fat all over your body, especially beneath the skin and around internal organs. An important note is that proteins are generally not used as the main resource of energy, except in extreme circumstances.

Men will use glycogen as the energy used while running whereas women can easily usefat and less carbohydrate at a given intensity of exercise. Men will need to recharge their hydrocarbon stocks to fuel their running capacity. It takes about 30 minutes to hydrocarbon/sugar to reach your bloodstream.

As a conclusion, women need to approach their training and racing differently than men to optimise their unique characteristics.

More than that, hormones in both males and females differ in amounts and in the effect that they have in the body. Indeed, for women, the best time to run is during the Follicular Phase, which is during your sixth to 15th day after your period. The differences occur in muscles and metabolism as well.

Being aware of these differences means is also a way to realise that your needs are different, that is why tailoring your diet and your training is necessary.

Women, you may be physiologically weaker, but you are still champions J

Alissa Laurent, a Canadian runnerwon the Canadian Death Race in 2015 and ended 90 minutes before the second winner, a man.

In short, women are scientifically better distance runners than men. So go ahead and with safe and consistent training, you can outrun the boys!

First published on 3 May 2017, rehashed and refreshed.

The real (and surprising) reasons healthy movement matters. It’s not about busting your butt to get a gym body. It’s about being capable, confident, and free.

When most people hear healthy movement, they think exercise or fitness or looking better or weight loss.

Sometimes, vanity.

Often, fitting into social norms.

“The man” telling you what to do (or how to be).

Moral righteousness packaged as 6am Hot Detox Spin-Late Pump class or an entire weekend of Instagram-worthy self-punishment.

But healthy movement is actually more interesting, liberating, and, frankly, crucial than all that.

In my years as a health and fitness coach, here’s the most important thing I’ve discovered: Developing a body that moves well is the ticket to a place where you feel — finally — capable, confident, and free.

We are all, literally, born to move.

It’s no secret: Human life has become structured in a way that makes it very easy to avoid movement.

We sit in cars on the way to work. At work we sit at our desks for much of the day. Then we come home and sit down to relax.

That’s not what our bodies are built for, so creaky knees, stiff backs, and “I can’t keep up with my toddler!” have become the norm.

Sure, if you can’t move well, it may be a sign that you aren’t as healthy as you could be. But the quality and quantity of your daily movement — your strength and agility — are actually markers for something much more important.

In my line of work, you watch a lot of people lose a lot of weight. The results would shock you — and I’m not talking about how they look on the beach in their bathing suits (although there is always a big celebration for that).

Most often, the thing people are most excited about after they go from heavy and stiff to lean and agile is this feeling that they’re now living better. They notice they’re:

  • more energetic and young feeling,
  • able to do things they’ve been putting off for years,
  • empowered,
  • proud of their lifestyle, and
  • free from many of the anxieties and limitations that held them back for so long.

They’re happier, but not just because they wanted to look better, and now they do. They’re happier because their bodies now work like they’re supposed to. They can now do things they know they ought to be able to do.

As humans, we move our bodies to express our wants, needs, emotions, thoughts, and ideas. Ultimately, how well we move — and how much we move — determines how well we engage with the world and establish our larger purpose in life.

If you move well, you also think, feel, and live well.

It’s proven that healthy movement helps us:

  • Feel well, physically and emotionally
  • Function productively
  • Think, learn, and remember
  • Interact with the world
  • Communicate and express ourselves
  • Connect and build relationships with others

We don’t need “workouts” to move.

Shocking secret: There’s nothing magic about a resistance circuit, the bootcamp class at your gym, or the latest branded training method.

Our ancestors didn’t need to “work out” when they were walking, climbing, running, crawling, swimming, clambering, hauling, digging, squatting, throwing, and carrying things to survive. Nor did they need an “exercise class” when they ran to get places, danced to share stories or celebrate rituals, or simply… played.

“Working out” is just an artificial way to get us to do what our bodies have, for most of human history, known and loved — regular movements we lost and forgot as we matured as a species.

We may not hunt for dinner anymore, and we may opt for the elevator more often than not.

We may move less. But movement is still programmed into the human brain as a critical aspect of how we engage with the world.

Therefore, to not move is a loss much, much greater than your pant size.

What factors determine how your body moves?

While there are universal human movement patterns, our specific movement habits are unique to us, and to our individual bioengineering.

Basically, the human body amounts to a sophisticated pile of interconnected levers:

  • Muscles are attached to bones with tendons.
  • These tendons connect to two (or more) bones across a joint.
  • When a muscle contracts, or shortens, the tendons pull on the bone.
  • That contraction and pull causes the joint to flex (bend) or extend (straighten).

How you move is determined by the size, shape and position of all of those parts, along with anything that adds weight, like body fat.

If you’re a tall person with long bones it may be harder for you to bench press, squat, or deadlift the amount of weight your shorter buddy can, because your range of motion is much bigger than your friend’s, so you have to move that weight a longer distance with much longer levers.

(This is why there aren’t many super-tall weightlifters or powerlifters, and why great bench pressers usually have a big ribcage and stubby T-Rex arms.)

But you can probably spank your short friend at swimming, climbing, and running.

If you’re bottom-heavy and/or shorter, you may not be able to run as fast as your taller friend. But you may have exceptional balance.

If you’ve gained weight in your middle (or if you’re pregnant), you may have back pain. That’s because the extra belly weight pulls downward on the lumbar spine (lower back).

When the lumbar spine is pulled down and forward (“lordosis”):

  • The pelvis also tips forward (“anterior pelvic tilt”), which pokes the tailbone back and the belly forward — aka Donald Duck Butt.
  • The upper/mid back may round to compensate (“kyphosis”).

The downward pull can also affect all the joints below (the pelvis, hip, knee, and ankle).

Conversely, it also works in the opposite direction, where, say, ankle stiffness can affect movement in the lower back.

If you have wider shoulders (“biacromial width”), then you have a longer lever arm, which means you can potentially throw, pull, swim or hit better.

If you have longer legs, then you have longer stride, which means you can potentially run faster. This is especially true if you also have narrower hips, which create a more vertical femur angle (“Q-angle”), allowing you to waste less energy controlling pelvic rotation.

 

Some variations in movement, we are given by nature and evolution. Other variations, we learn and practice.

If you’re a woman who’s top-heavy, you may have developed a hunch in your thoracic spine (upper and mid-back), whether from the physical weight of your breasts or from the social awkwardness of being The Girl With Boobs in middle school.

Or, if you got really tall at an early age, you may have developed a habitual hunch to hide your size or communicate with hobbits like me.

Yet the structural engineering remains important. Especially if we understand how our structures and physical makeup affect our movements.

For instance:

Body fat and weight change how we move.

This is especially true if you don’t have enough muscle to drive the engine.

At a healthy weight, your center of mass is just in front of your ankle joints when you stand upright.

However, the more mass you have, especially if you have extra weight in front, the harder your lower legs and feet have to work to keep you from tipping forward.

This puts additional torque (rotational force) on ankle joints.

 

Once you start walking — which is, essentially, a controlled forward fall — you have to work even harder to compensate.

Any unstable or changing surface (stairs, ice, fluffy carpet, a wet floor), requires your lower joints to adjust powerfully and almost instantaneously — literally millisecond to millisecond.

As a result, obese children and adults fall more often.

Human bodies are amazingly adaptable and clever, but nevertheless, physics can be an unforgiving master.

The good news is that this is generally reversible.

No matter where you’re starting, the more you move, the better your body will function.

When we move:

  • our muscles contract;
  • we load our connective tissues and bones;
  • we increase our respiration and circulation; and
  • we release particular hormones and cell signals.

All of these (and a variety of other physiological processes) tell our bodies to use its raw materials and the food we eat in certain ways.

For instance, movement tells our bodies:

  • to retrieve stored energy (e.g. fat or glucose) and use it;
  • to store any extra energy in muscles, or use it for repair, rather than storing it as fat;
  • to strengthen tissues such as muscles, tendons, ligaments, and bones; and
  • to clear out accumulated waste products.

And improved body functions ensure you’ll be able to move well and:

  • climb stairs or hills
  • step over obstacles
  • carry groceries
  • stand up from sitting down, or get up from the floor
  • grasp and hold objects like a hammer
  • pull or drag things like a heavy door or garbage can
  • walk an excitable dog

The more we can do confidently and capably, the fitter we’ll be. Even better, that means we’ll do more. That leads to more fitness. And this virtuous cycle continues.

 

Movement does more than just “get us into shape”.

Despite eyeglasses and iPhones, humans are still animals. We’re meant to move with the grace and agility of a tiger (or a monkey). And movement offers us a tremendous number of (sometimes surprising) benefits.

 

Movement is how humans (and other animals) interact with the world.

As babies, we immediately start grabbing things, putting things in our mouths, reaching for things, and clinging to our (now less furry) primate parents.

We are tactile, kinesthetic beings who must directly interact with physical stimuli: touching, tasting, manipulating, moving ourselves around objects in three-dimensional space.

Movement helps us connect and build relationships with others.

Movement is a sensor for the world around us.

In one study, when people’s facial muscles were paralyzed with Botox, they couldn’t read others’ emotions or describe their own. We need to mimic and mirror the body language and facial cues of one another to connect emotionally and mentally.

From the puffed-chest posturing of drunken young men outside a bar, to Beyonce’s fierce dance moves, to the mating rituals like close leaning and eye contact, to the laser stare your mom gives you when she knows you’re up to no good:

Movement gives us a rich, nuanced expressive language that goes far beyond words, helping us build more fulfilling and lasting relationships, with fewer misunderstandings, disconnections, or communication bloopers.

Movement helps us think, learn, and remember.

You might imagine that “thinking” lives only in your head.

But in reality, research shows we do what’s called “embodied cognition” — in which the body’s movements influence brain functions like processing information and decision making, and vice versa.

So “thinking” lives in our entire bodies.

But even if thinking were limited to our brains, there is evidence that movement and thought are intertwined.

It turns out that the cerebellum — a structure at the base of the brain previously thought to only be used for balance, posture, coordination, and motor skills — also plays a role in thinking and emotion.

Also, movement supports brain health and function in many ways, by helping new neurons grow and thrive (i.e. neurogenesis).

Every day, our brains produce thousands of new neurons, especially in our hippocampal region, an area involved in learning and memory. Movement — whether learning new physical skills or simply doing exercise that improves circulation — gives the new cells a purpose so that they stick around rather than dying.

Thus, movement:

  • helps maintain existing brain structures,
  • helps slow age-related mental decline,
  • helps us recover if our brain is injured or inflamed,
  • lowers oxidative stress, and
  • increases the levels of a substance known as brain-derived neurotrophic factor, or BDNF, which is involved in learning and memory.

Move well, move often, get smarter.

Movement affects how we feel physically and emotionally.

People of all shapes and sizes say they have a better quality of life, with fewer physical limitations, when they are physically active.

If you exercise regularly, you probably know that kickass workouts can leave you feeling like a million bucks. (Personally I think of mine as anti-bitch meds.)

Research that compared exercise alone to diet alone found:

People who change their bodies with exercise (rather than dieting) feel better — about their bodies, about their capabilities, about their health, and about their overall quality of life — even if their weight ultimately doesn’t change.

(Now… just imagine if you combined the magic of exercise with brain-boosting and body-building nutrition!)

Find out what “healthy movement” looks like for you.

Not everyone has to be (or can be) a ballet dancer or Olympic gymnast. As a 5-foot, 40-something woman who can’t run well nor catch a ball, I’m fairly sure the NBA and NFL won’t be calling me.

But I’m also not saying that, “Well, guess I shouldn’t climb the stairs because of my Q-angle” is the way to go.

I’m saying: Today, pay special attention to how you move.

Be curious.

As you go through the mundane activities of your day, notice how your unique body shapes your movements.

How do you move… and how could you potentially move?

In our coaching programs, we work with a lot of clients who have physical limitations, such as:

  • chronic pain or movement restrictions — say, from an injury or inflammation.
  • too much body fat and/or not enough lean mass.
  • too many or too few calories/nutrients to feel energetic.
  • age-related loss of mobility.
  • a physical disability.
  • neurological problems.

You may have some body configuration that makes it easier or harder for you to do certain things.

We all have structural or physical limitations. We all have advantages. It all depends on context.

Regardless of what your unique physical makeup might be, there are activities that can work for you, and help you make movement a big part of your daily life.

Ask yourself:

How can I move better — whatever that means for MY unique body? And what might my life be like if I did?

And finding someone who can help you if you think that’s what you need.

What to do next

1. Pay attention to how it feels to move.

“Sense in” to your body:

  • When you walk or run: How long is your stride? Do your legs swing freely? Do your hips feel tight or loose? What are your arms doing? Where are you looking?
  • When you stand: How does your weight shift gently as you stand? What does that feel like in your feet or lower legs?
  • When you sit: Where is your head? Can you feel the pressure of the seat on your back or bottom?
  • When you work out: Can you feel the muscles working? What happens if you try to do a fast movement (like a jump or kick) slowly, and vice versa?

2. Consider whether you’re moving as well as you could.

Do you feel confident and capable? Ninja-ready for anything?

Do you have some physical limitations? Do you have ways to adapt or route around them?

When was the last time you tried learning new movement skills?

What movements would you like to try… in a perfect world?

3. Think about other ways to move.

If you’re working out a certain way because you think you “should”, but it’s not fitting your body well, consider other options.

Or, if your current workout is going great but you’re curious about other possibilities, consider expanding your movement repertoire anyway.

Everything from archery to Zumba is out there, waiting for you to come and try it out.

Remember: You don’t have to “work out” or “exercise” to move. And you don’t need to revamp your physical activity overnight, either.

Take your time. Do what you like. Pick one small new way you can move today — and do it.

4. Help your body do its job with good nutrition.

Quality movement requires quality nutrition.

And just like your movements, your nutritional needs are unique to you.

Here’s how to start figuring out what “optimal nutrition” means for you:

If you feel like you need help on these fronts, get it.

A good fitness and nutrition coach can:

  • help you find activities that suit your body.
  • review your nutrition and offer advice on how to improve your diet (even if your life is hectic).
  • help you identify any potential food sensitivities that could be causing or worsening inflammation and thus restricting your movements.
