Increasing energy with exercise

Increasing energy with exercise:  How does exercise increase our energy?

VO2

Improving the fitness of the heart and lungs through cardiovascular/aerobic exercise increases our VO2.  The higher our VO2 the more efficient we become at creating energy for ourselves by combining oxygen with glucose to make ATP.

Heart

Increasing fitness will increase the strength of heart. The heart can work more efficiently, expelling more blood with each beat.  More blood = more oxygen which means fewer beats required for any activity that increases the heart rate.

Strength

When we improve the strength of our muscles we do not need to max out our muscular effort.  If we could only lift 10 lbs of groceries, and now we have increased our strength to be able to lift 15 lbs of groceries, the 10 lbs will seem easy, with less effort required.  Therefore, more “energy” will be left over for other activities. 

Endurance

The same goes for endurance of a muscle.  I had a colleague that was used to treating shoulder problems. She decided to help out on the post-operative floor getting patients out of bed.  Half way through the morning, her back was sore and she needed a break.  The endurance of her back muscles was not sufficient for the task at hand.  Her back muscles were out of gas before the morning was over.  

Flexibility and range of motion

Having the flexibility and range of motion needed for a task will help conserve our energy bank.  For example, if you sit a lot, and have tight hip flexors (quad/psoas), every time you try to stand straight, there will be some relative resistance to standing straight.  This ultimately results in an increased use of our extensors(back and hips) and may make standing straight more effortful.

Endorphins

Endorphins are released during exercise and can make us feel lighter and brighter on a physical and cognitive level . Endorphins can also decrease the experience of pain. This may result in a reduced level of stress, leaving more energy for other tasks.

Exercise and injury: We all have our limits

Why do we injure ourselves?

Did we do too much too soon? Did we go beyond our physiological limits? Maybe we have an underlying problem that keeps resurfacing? Maybe there is something going on in our biomechanical bodies that we are not fully aware of or understand. Maybe we have been a consistent exerciser and have been doing the same thing for years? Did you try something new and didn’t really know the basics? Are you a weekend warrior?

Tissue tolerance

Exercise and injury. There are a multitude of possibilities. But I would say in most cases, we have exceeded our tissue’s tolerance. Not a great layperson term, but it kind of summarizes it all into one box.

Our bodies our made of different tissues, and I am speaking very generally from a biomechanical perspective: we have bones, joints, muscles, tendons, ligaments, blood vessels, fascia, skin, and nerves that represent the physical entities that make up our musculoskeletal system, the one that moves our limbs, maintains our posture, allows us to move from one place to another, fidget or reposition, and of course carry out out daily tasks(even sedentary ones) as well as exercise.

We exercise to keep this system primed and ready for action. The less we move, the more limited our movement repertoire becomes. By checking in with your body regularly, responding to and modifying our physical routines, we are more likely to get the balance right.

Exercise and injury. Think about the following :

Consistency of exercise (how regularly do you exercise?)

Volume of exercise (number of repetitions or repeated movements in a session or specified time frame, eg. number of steps in a day)

Impact (high or low impact, which one do you do?)

Range (does your flexibility or available joint movement match what is required for your chosen activity?)

Force or strength requirements (are you loading a tissue too little, just right, or too much? It depends on your goals)

Frequency (do you have rest days in between workouts? Do you workout once a week or daily, or work different parts on different days?)

Technique (what are you doing, why are you doing it, and what is the best technique, alignment, speed, rhythm, or range to do it at)

The above list is very generalized, but you can see there are multiple modifiable factors that can affect the tolerance or resilience of our tissues, and in turn, when it results in injury or having “overdone it”.

If you are a high level athlete versus a grandmother who takes care of her grandkids, you will likely have different goals when it comes to your fitness and lifestyle. Try not to compare yourself to others when thinking about what kind of program you should do.

See my blog called Exercise specificity: what do you need? for help in figuring this out.

Let’s be realistic

Exercise and injury do not need to go hand in hand. I think in many cases our ego gets the better of us. Or maybe it’s our memory (or inserted memory, a.k.a. delusion). Our inability to be in the moment with our bodies may result in participating in an activity in a manner that was better suited to a younger version of us, many years or even decades ago. In this case, re-evaluating how you feel during or after your activity of choice may help you refine and remodel the way you do things, matching it more closely to your current abilities or physical capacity.

Training

If you know you are training for a future event which will require a level of fitness that exceeds your current fitness level, educate yourself, use common sense, ask questions and look for advise from those who appear to be successful in the same activity. This may increase your odds of avoiding injury and completing your goal. I think one of the best things you could do is be realistic on time. Give yourself more than enough time to prepare for the event.

Fuel

We know that the resilience of our tissues also depends on the fuel we use to sustain activity and to build and regenerate new tissue. This gets even trickier, as there are so many views on nutrition, and everywhere we look there is advise on how to best address this. Find someone you trust and whose perspective is similar to yours when it comes to food choices. Start with the obvious by making healthy food choices(i.e. avoiding junk food, highly processed food). Eat what you know is healthy more often.

Consistency

Exercise and injury. My last thought is think about consistency. If you only dabble in exercise or in intentional physical activity once in a while, start with one day a week, or one activity that you can do well. Develop a basic schedule that you can stick to. Find a place for it in your calendar and make that the beginning of your “exercise week”. You may find that planting the seed (deciding when, where , what and how) and then cultivating it (completing it at the beginning of your “exercise week”), may result in new “buds” in unexpected areas.

Motivation to exercise

Exercise for the most part should be fun. If you hate it, maybe you are doing the wrong thing. The options when it comes to exercise and physical activity are endless. You don’t need to fit into any mold. If something works for you, stick with it. Then see if there are ways to expand your horizons, and switch it up a bit.

If you really do not know where to start, talk to someone who should know, and don’t feel intimidated. It doesn’t take much to get moving. And once you find the beginning of your path, it could take you anywhere.

It’s OK to “start over” many, many times. Keep at it, and soon you will feel something stick. You’ve got to move, and I have no doubt that you can do it!

Let me help you get started

If you need help, accountability(and I mean this in the lightest sense) or just to know that you are not alone in your exercise journey, join me in September for weekly motivational movement, exercise demos, conversation and fun! It won’t be complicated. Stay tuned!

Anatomy, physiology and aging, Mental health & stress

Muscle tension

Have you noticed that we use the same words for “good” muscle tension and “bad” muscle tension? What’s the difference?

Here are two types of muscle tension:


1) A muscle has to generate tension to exert force at a joint. This may or may not result in observable movement. This is what we do when we are trying to strengthen or contract a muscle. This type of muscle contractions could be concentric (muscle actively shortens), eccentric (muscle actively lengthens against a load or gravity) or it could be isometric (muscle length is unchanged during a contraction).

2) A muscle that “should” be at rest but is still generating tension and/or movement. This may be the type associated with mental stress. Areas where we may feel this “tension” is the neck, jaw, hands, chest and abdomen. It really could be any muscle. We may tighten the muscles in these areas inadvertently in response to stress.

Either way you look at it, muscle tension is created through muscle contractions, voluntary or involuntary, done consciously or unconsciously.

So why should you care?

Because we have control over both types of tension, even the one that seems to be more “unconscious”. And one of the best ways to learn how to “release” or “exert” muscle tension is through exercise. Exercise helps us to increase our kinesthetic awareness. More simply, exercise can help us feel and understand our bodies better, and become more adept at modifying muscle tension according to our needs.

Even better, if our focus is to “release” tension, there is a reciprocal inhibition of one muscle over another with every muscle contraction. This means, if I want to release tension in my tricep (located on the back of my upper arm) then one way to do this is contract the opposing muscle (bicep) on the front of the arm.

Do you want your muscles to get stronger to improve function or do you need to release and learn how to “let go”?

Probably a bit of both. So why not move with intention at least once daily? This could be a walk, an exercise video, an exercise class virtually or in person, a personal training session, swimming, or multitude of other physical activities. Start with what is familiar and preferably at least mildly enjoyable. Buddy up with someone who is looking to do the same thing.

When you exercise regularly or intentionally move on a consistent basis, you will slowly learn more about your body and how it feels after certain activities. You will become better at determining when a muscle is “on” for the purpose of strengthening, or if it is “on” because of habits that have connected our mind’s stress to a physical response in our body.

If you would like to learn more about your body through movement, Essentrics is a great place to start. Essentrics uses all types of muscle contractions and will help you zone in on areas where you need to release.

Exercise specificity: What do you need?

Leave a comment

When it comes to exercise specificity, start by asking yourself: “What do I want” from my exercise program? Do you want better posture, to be more flexible, to decrease stress levels or improve heart and lung fitness? If you are not sure where to start, and feel there are too many options to choose from, you may want to consult with an exercise specialist to guide you on the path of specificity.

If you can identify activities or tasks that you would like to be able to accomplish or do better, this will help you and your specialist to figure out what will give you the results you want. Exercise may not be the answer to all of your problems, but it is one of the few modalities whose benefits go beyond just physical fitness. “I just want to get fit” is a great goal, but knowing what you mean by getting fit will help you to define and ultimately refine your exercise goals.

Strength,
Endurance,
Cardiovascular fitness,
Joint mobility,
Flexibility, …

What do you want? What do you need?

If you know what your end goal (or intermediate goal) is then it may fall under one or all of the categories listed above.

Here are examples of what each category represents:

Strength: You want to be able to do a push up. You think it would be great if you could do 10 regular push ups.

Endurance: To be able to stand in the kitchen and bake for 2 hours without pain and without feeling exhausted

Cardiovascular fitness: You want to be able to jog a mile and and be able to breathe at the same time

Joint mobility: Making kneeling for short periods of prayer possible

Flexibility: You want to be able to touch your toes from standing

It’s never too late to try something new

Here are examples of what I do for myself to address the above categories:

Strength: lower body “slider’ lunge series as well as lower body weight training.

Endurance: daily walks to and from work. Continuous non stop workouts like circuits or interval training.

Cardiovascular fitness: steady state running on treadmill or outdoors. Alternate stationary cycling. Interval training is also an option here too.

Joint mobility: ankle mobility exercise using a step

Flexibility: Essentrics is an exercise program where I am able to perform many combined movements and sequences which can address flexibility along muscular or fascial “chains”.

Simplifying exercise specificity

Here is an example to pull it all together.

GOAL:

You are recovering from knee replacement surgery. You are 3 months out. In another 3 months time is your grand daughter’s wedding and you want to be an integral part of the ceremony and reception. Standing and walking for several hours at a time is likely. Navigating on uneven ground is a given (it’s an outdoor ceremony on grass). You will be helping with the organization of the reception, which require you to climb a small set of stairs numerous times. You may need to carry some lighter items like wine bottles, if the server runs out.

CURRENT STATUS:

You have already been climbing stairs daily but only once or twice as needed. You still need the railing and sometimes need to use a cane as well. Twice weekly you go out for a walk with your friend Pat. Pat’s pace makes you move a little faster than you would on your own, for approximately 45 minutes. You usually take 2 canes to help you keep up. You don’t spend much time on grass.

PLAN:

Based on this description, you would probably need your exercise routine to focus on lower body endurance for standing, walking and stairs. You likely will have some strength gains to be made, to improve your stair performance and ability to walk safely without support (especially if you need to carry a bottle or two). The other focus may be cardiovascular fitness, so you can last the entire day without feeling significantly tired. This will be important as the wedding day progresses, as your risk of falls on grass is higher than it would be on level surfaces. Your ability to make good choices and move with care will be affected by your energy levels. Check out Keeping it real: Physical fitness and VO2max for more on cardiovascular fitness.

Exercise specificity

So as you can see, there could be many layers to “getting fit” so finding what is specifically important to you will make both the the work of exercise and the gains made from exercise that much more meaningful. And remember, any daily intentional physical activity, like your walks with Pat, will be part of your plan. Take all the help you can get, and start making the changes that will truly have an impact how you live and feel. It’s worth it. So let’s GO!

Keeping it real: Physical fitness and VO2 max

1 Comment

I was a runner back in high school. Mostly distance. But even as a youth it was easy to delude myself on my level of physical fitness. I remember running a cross country race where I had barely trained for it. We did not have a coach that year so we had to train ourselves as a group. Despite having run cross-country ever since I was 9 years old, I “forgot” what it took to be competitive. Without the external driving force(our coach) it was very hard to max out with speed drills and progressive endurance training. I had just finished a summer of partying and eating McDonald’s regularly so the extra weight and new outlook on life didn’t help things.

I had ran the exact same race several times in the past. I recall watching other races with runners who were falling behind shortly after the initial 3/4 sprint start. I remember the winded looks and trudging bodies that looked like they may collapse at any minute. I never imagined myself in their shoes. I would say to myself, “well at least they were trying.”

Obviously, I spoke too soon. I joined my new cohorts with a vengeance. I didn’t just stop at placing poorer than I ever had. I came in last. No joke. People on the sidelines cheered me on, “Come on West Hill!”. In the moment, I wanted to tell them to go fly a kite. It was extremely difficult not to walk off the course and cry in the bushes because of the level of humiliation that I felt. If I hadn’t heard those few words of encouragement I probably would have.

The real problem was that I already knew the method to the madness. My physical capacity for running was seriously depleted and I found out the hard way. It wouldn’t be the last time, but delusional moments following that episode were not nearly as extreme. I was learning, slowly.

VO2 max and muscle endurance.

We use the word fitness as a descriptor of our physical health. It is a general term and may encompasses many different components. The one measurement of our fitness that relates to our capacity to carry out our daily activities is our VO2 max. It is a measure of our heart, lung and circulatory fitness, in others words, our cardiovascular fitness. More specifically, it is the maximum amount of oxygen you can utilize during exercise. Its the critical one that if reduced to a level that is too low, we won’t be able to produce the energy required to get out of bed.

Now let’s take it up (or down) another level. You used to manage the 2 flights of stairs at your workplace but you discontinued that activity because you were working from home. Then you were forced to take the stairs one day and you are stunned by your body’s response. Your head feels dizzy because the level oxygen to your brain has been impacted. Maybe your blood pressure has shot up secondary to your heart’s attempt to supply your body with more oxygen. Your heart is racing and you are out of breath.

You may still have the basic mechanical capacity to do the stairs(i.e. enough strength and joint mobility) but you don’t have the muscle endurance and cardiovascular fitness to support the “sustained” activity.

How to improve your heart and lung fitness.

The best thing about cardiovascular fitness or VO2 max is that it can be improved through physical activity. If you have cardiovascular disease then you may need more guidance but everyone can benefit and make gains.

You need to do something that is beyond your normal level of exertion. You can usually tell if you are accomplishing that by your heart rate and respiratory rate. Of course, if you are seriously deconditioned or have any medical issues you may need to consult with a health professional. If you don’t know, get some help.

Moral of the story

Coming in last was not the worse thing in the world. But I sure felt like crap in more ways than one. It’s so much easier to maintain fitness with a sustainable daily commitment to exercise and/or intentional physical activities that challenge you. If we do that little bit more, everyday, our bodies will adapt appropriately over time.

Figuratively, we need to keep climbing hills everyday to challenge the body to keep up. It naturally wants to decline, and with age, even more so. We need to continue moving towards a higher base camp, higher than the one where we left off. Without activity, we end up progressively going downhill to the lower base camp and eventually we find ourselves below sea level and not even sure how we got there.

Keeping it better than real

Keeping it real will allow you to continue to be able to do all the things you enjoy doing. Knowing that you could do more is even better. Stay in tune with your physical abilities and don’t let them slide. Stay up on the highest base camp possible. There’s no rush to get to the top but don’t inadvertently coast downhill and let the clutch out too soon. Apply the gas gently and progressively. You will be amazed where you can take yourself!

Alright now, let’s GO!

Anatomy, physiology and aging, TIps

Hips: Love em or leave em?

I love my hips. I’ve never had a bad relationship with them. I have never had any chronic pain as an adult. I do recollect deep groin pain as a youth in ballet class. In any case, I care about my hips and want to keep them in the best shape possible. Without their health, I know my life would be significantly impacted. I want to stay ahead and not get behind in their abilities.

My hips are not symmetrical. They move differently. I’ve gotten to know them well through years of dance and physical activity. They are twins but with unique personalities. I don’t love one more than the other. They have their individual strengths and relative weaknesses (credit: wise yoga instructor).

Lately, I have had some knee cap pain. While I am recovering from my knee dysfunction I have placed a special emphasis on knee and hip strengthening because they are kind of best friends. Can’t treat one without the other. They are intricately connected and when one suffers they tend to commiserate together. Maybe not overtly to the untrained eye. You have to look for it. And sometimes not.

Why hips are important

Back to our star pupil. The “biggest” joint in the body. Lost in the depths of the body but not forgotten. Buried in mystery and sometimes esoteric associations. We are obsessed with our “hips” for lack of a better term. It includes the hip joint proper(the ball and socket), housed in our pelvis and all of the musculature surrounding it. Together they act as a fulcrum connecting the upper and lower body folding us in half. Unilaterally, they balance our torso via the pelvis, allowing us to translate ourselves from point A to B.

When you think about what happens when we walk, its pretty complicated. The hips are a major component in the balancing act of walking, alternately suspending ourselves on one limb at a time, propelling ourselves forward, backward or side to side. Through our connection with the ground we generate forces that move our bodies in the direction we choose. We would have a very hard time doing this with out the health of our hips.

Taking the mystery out of hip pain and joint imbalances

What happens when the hip joint is unbalanced? The balance of the ball and socket and all of the muscles surrounding them, both deep and superficial, sometimes seems too complex to decipher. When the hips are unbalanced we may shift unintentionally in the wrong direction which then requires even more energy to redirect our momentum. We create alternate strategies that overtime may be even more detrimental to our posture and mechanics.

It’s a special joint that gets a lot of attention. Rightly so. When the hip is unwell there can be a chain effect upwards towards our spine and downwards towards the soles of our feet.

So given our apparent focus on our hips, why the mystery? There are several popular hip muscles that are frequently associated with having great importance. Just as frequently, these muscles are labelled as critical links that once uncovered will reveal the solutions to all of our problems. The ones that come to mind are psoas, gluteus medius and piriformis. Hamstrings and gluteus maximus? For some reason they don’t get the spotlight. I guess they are boring and too obvious. The reality is that we need every part of our hip musculature to work in optimal lengths with optimal strengths, and we need them to be in use on a daily basis.

When I am trying to figure out a hip problem, I look for the “gross” imbalances. Front versus back. Side versus inside. Deep fine tuners versus superficial power houses. Some groups of muscles become more dominant than the other because of habitual postures and repetitive activities. It could be that our exercise program is a little biased and doesn’t “round out” our hips’ basic needs.

The pelvic floor and hip joint stability

There are also hip joint muscles that are very closely associated with the pelvic floor. Dysfunction in one area may affect the other. Maybe we consider the hips to be so precious because of their proximity to our sexual organs. The hips’ close association with the back can also make the pain picture sometimes confusing.

But the hips are not fragile unless you have osteopenia or osteoporosis or another bony pathological condition. They are required to take on a significant load and when injured often require extensive retraining to restore the normal length and strength of the musculature. We often need to re-learn how to stabilize the pelvis on the femur via the hip joint. There are rarely any quick fixes involving a single muscle that will ultimately eliminate hip pain or restore ideal function.

Keeping our hips healthy.

Keeping our hips healthy should be a focal point of everyone’s day. And one simple way is too get off of your buttocks and stop sitting for prolonged periods. We have all heard about how our sedentary lifestyles which involve prolonged sitting have replaced cigarette smoking as a major lifestyle factor that is detrimental to our overall health.

A great suggestion is to get out if you chair every 20 minutes. Set a timer so you won’t forget. Stand up and straighten your hips. Get them out of that passive folded position. Take a short walk around your space. Walk forwards, backwards and sideways if you can. Tighten your glutes and remember that they should not feel anything like pancakes i.e. flat and soft.

So, love your hips. Don’t leave them unattended. Intend to keep them in shape and they will thank you by keeping you moving with ease and accuracy. Love thy hips as they are incredible and special joints. Keep things simple by giving them what they need on a regular basis. If you are not sure, find someone to help you figure it out. Don’t give up on them. They are worth the consistent time and the effort to keep them lubricated, flexible and strong.

Upward (from the chair)

and onward (propelling yourself through space)!

Let’s go!
