Stand-Up Paddle Boarding for Core Strength, Balance and Total Body Fitness!

 


Stand-up Paddle Boarding (SUP) is a fun activity that almost anyone can learn, and it is one of the best workouts available!   Stand-up Paddle Boarding is low impact and provides a combination of balance, core, strength, and endurance.     Since you are standing you have to use everything from your feet (wow do you use your feet!) all the way up through your entire shoulder girdle.    Because you are standing your arms never have to go above shoulder height which means that there is much less stress on the rotator cuff muscles than kayaking.    You use your shoulders heavily but your shoulders are stressed in the position where they are naturally most stable and strong so much better than kayaking for those with shoulder and neck issues!

Just standing on a Paddle Board forces you to stabilize your entire body and core, and it is one of the best activities available to develop balance.   Best of all if you do fall you land in the water and getting back on the board is very easy!  

 SUP Technique Breakdown

Learning to SUP is easy but mastering the stroke and maximizing your speed takes lot of practice.  The first thing to focus on is NOT pulling the water!     Instead you want to plant the blade in the water and pull yourself and the board up to the paddle blade.   Imagine that you are stabbing the paddle firmly into soft sand then pulling yourself and the board up to the paddle.   If you can clearly visualize the difference here it will go a long way to getting your stroke where it needs to be for optimum speed.   Think about grabbing the water NOT pulling the water by you!

 Reach

Once you get a little feel for it start looking at how far you are reaching forward to put your paddle in the water.   You want to reach as far as possible each time you stroke, BUT there is a limit based on your particular anatomy, shoulder strength and balance.    If you reach too far you can overstress your low back, shoulder or just be off balance which is counter-productive.

 Catch

This is where the blade of the paddle enters the water.    Make sure the entire blade enters the water before you begin to pull.   The catch should be as smooth and clean as possible with no splashing.

 Pull

Now you are ready to apply power to the paddle.   Use your entire body for this part of the stroke.   It is NOT about using your arms.   Rather your arms merely connect you to the paddle through your hands and you use the rotation of your torso, hips, and shoulders to drive your paddle!  Try to relax your arms as much as possible to perfect this technique. Do not pull too far back as this will actually slow you down.   Once the paddle passes your hips if you keep pull you are actually pulling the paddle up meaning you are pulling the paddle board down and this only slows you down.

 Release

After the pull you need to release the paddle from the water.    Like the catch you want this movement to be quick, smooth, and with zero splashing.   Feathering the blade of the paddle creates a smooth release and set-up for the next catch.   You feather by dropping your top shoulder, “breaking your wrist inward”, or a combination of both.  

 Recovery

Once you release the paddle you are ready to set-up for the next catch and pull.   Try to relax during this phase – the key to optimum paddle technique is learning to set a rhythm between tension and relaxation and ultimately getting your breathing into a rhythm with the stroke.  The first time you feel this come together it is amazing – really zen!  So stay relaxed and let go of the tension you produced in the catch and pull and smoothly swing the paddle forward to prepare to drive the blade fully into the water for the next pull!

 How many calories can you burn Paddle Boarding?

Obviously your actual calorie burn will depend on the intensity of effort you are putting into to paddling along with your height, weight, and the wind and water conditions you are paddling in.     However here are some estimates based on people weighing between 165 and 200lbs :

            Casual Paddle Boarding – 300 – 430 calories per hour

Yoga on Paddle Board – 416 – 540 calories per hour

Touring on a Paddle Board – 615 – 708 calories per hour

Surfing on a Paddle Board – 623 – 735 calories per hour

Racing a Paddle Board – 715 – 1,125 calories per hour

So if you have not taken the plunge yet – google “Stand-up Paddle Board Rental” and find a rental location and give it a whirl.   Rentals including paddle, board, and lifejacket are generally $25 - $35 per hour so get out there and give it a go!

Does Your Metabolism Slow Down as you Age?

 


The answer used to be yes, but recent research has proved that this is NOT the case!   The current research used a method to measure metabolic rate called doubly labeled water.    This involves giving people water with Deuterium (a form of hydrogen) and Oxygen-18 which is a specific form of Oxygen.

Then using urine samples scientists measure how much of each of these unique forms of Hydrogen and Oxygen are being eliminated.   This allows them to know the rate of carbon dioxide production with extreme precision over a long period of time.

Carbon dioxide production can be used to directly and accurately determine calorie burn and metabolic rate.      Doubly labeled water is the Gold Standard for measuring calorie burn/metabolic rate, and this is the first time it was used to accurately measure metabolic rate in over 6,421 people from 29 countries looking at metabolic rate in people from 8 days old to 95 years old.

Game Changer

The result of the study clearly proved that metabolic rate does NOT slow down because of aging between the age of 20 and 60.     After 60 metabolic rate does gradually slow down, but it is very gradual. 

Another surprising finding was that babies have a much higher metabolic rate (50% higher than adult values) meaning that on a pound for pound basis babies burn a lot more calories than adults.

This high metabolic rate declines slowly from birth to age 20, but after that stays very stable until after age 60.   So it IS true that children and teens have a higher metabolic rate.

Take Home

Although metabolic rate burn does not slow down from aging in and of itself - other factors can result in your metabolic rate slowing down!   Loss of lean mass with aging can and does result in a slower resting metabolic rate.    The loss of muscle from aging, known as sarcopenia, CAN result in a lower metabolic rate.

To make things worse the more muscle you lose the lower your activity levels tend to be and it becomes a viscous cycle:    lower muscle = less activity = less muscle!

This is why it is so critical to include strength training in your fitness program as you age because it can prevent this loss of muscle and help maintain higher activity levels and metabolic rate!

Tendon Strength - the Key to Maximum Power Output!

 


Although strong muscles are important for health and athletic performance -the key to high level athletic performance is power which is the ability to produce a lot of force quickly.    This takes more than regular strength – the secret is being able to store and release elastic energy to create more explosive movement.   By understanding how power is produced, we can keep people walking, running and jumping into older age and how to walk again after injury or illness.

Storing and releasing energy is known as the stretch-shortening cycle or muscle-tendon elasticity.     These cycles are the foundation of ALL human movement, and this is not just about muscles – tendons are key!   Tendons attached muscle to bone are very strong.

In fact, in the most powerful, explosive athletes – their tendon strength is much higher than the average person and this is key for power production as we will see.

Muscle Strength and Contraction Speed

Although muscles can be very powerful (calf muscles can produce upwards of 1,000lbs of force) they have one big limitation.    Muscles can only shorten/contract so fast – even in the fastest athletes.    In fact, at high speeds muscles can produce very little force at all while shortening.   This is important because muscle shortening, known as a concentric muscle contraction, is how force is applied to external objects including the ground!

To make it even more confusing - when athletes move at the fast speeds their muscles cannot produce force fast enough to help while shortening – so how do they move so fast?

Tendon Stiffness

Humans, like most other animals on Earth, make use of something called the stretch-shortening cycle aka muscle-tendon elasticity which allows us to store and release energy rapidly when needed.

The stretch-shortening cycle relies on our relatively long, stretchy tendons attached to a strong muscle and bones. Tendons are what attaches muscle to bones. When the muscle produces force it stretches the tendon, storing elastic energy. The subsequent recoil of the tendon generates way more power than our muscles are capable of producing. Our tendons act as power magnifiers!

To take advantage of this ability people intuitively learn that they need to move in the opposite direct of desired movement (called “counter-movement”).   For example:  if you ask anyone to jump as high as they can you will see them squat down and then rapidly change directly to jump up!   This results in energy being stored in the tendons as the muscles lengthen which is then released as the muscles stop lengthening and shorten rapidly as the person jumps up!

Stiffer Tendons and tendons that are stretched further can store more energy and generate more power during recoil. Because most of the power used in running and walking comes from the ankle joint – it should be no surprise that the Achilles Tendon of Runners are stiffer than the average person!

Eccentric and Isometric Muscle Contractions

The key to fast, explosive movement is the stiffness of tendons combined with the proper use and timing of isometric and eccentric muscle contractions.   Optimizing this technique is one of the keys to optimal athletic performance.

Isometric contractions are used to prevent movement such as during the plank exercise where the core is working to prevent sagging of the low back.   There is no muscle movement during isometric contractions.

Eccentric contractions are used to absorb force like landing from a jump and muscles are lengthening under tension.

We engage eccentric contractions during the counter-movement which occurs immediately before we produce a strong concentric (muscle shortening contraction).    For example, in running when we land the ankle, knee and hip joints flex and the muscles around these joints lengthen under tension to absorb the impact of landing.  

Then we couple this with isometric contraction at the bottom of the counter-movement to stop briefly.   Then finally we rebound back up using the energy stored in the tendon to generate MOST of the force needed.    Over 70%  of the energy for efficient human movement is produced through this and process and NOT produced by concentric/muscle shortening contractions!  

The faster we run the more energy we store and the more recoil energy is released from the tendons.   This occurs even in walking and allows us to move more efficiently and at high speed!

How to Improve the Stretch-Shortening Cycle and Power Output

Part of our ability to optimize the stretch-shortening power cycle is determined by genetics, but it’s also something we can improve through training. Technique training helps, but also the use of heavy strength training and eccentric dominant training can both help to improve tendon strength and stiffness.

As we age, our tendon stiffness and power output decrease, and this means we lose movement efficiency and must use more energy for activities like walking because we get less recoil energy from our tendons.

People with less stiffness in their Achilles’ tendon (and the accompanying lower strength in the calf muscles) have slower walking speeds.    Also walking speed is directly related to mortality and morbidity in the elderly so maintaining tendon stiffness is important as we age.

The greatest force for walking, running and jumping is produced at the ankle joint. This is an important target for athletes, but also for anyone who wants to maintain their walking, running, jumping capacity as they age.

How to Build and Maintain Stronger Tendons 

They key to building tendon strength is focusing on the eccentric/muscle lengthening aspect of strength training.    This can be challenging to do, and one of the best ways to build this strength is the use of the reACT Trainer – www.reacttrainer.com Nothing does a better job of safely improving eccentric lower body strength and endurance and accompanying tendon strength and stiffness.

It is also good to specifically keep your ankle muscles conditioned by doing calf raises with resistance.    The calf and ankle joint can produce enormous amounts of force so as the exercise gets easier add more resistance to continue to build muscle and tendon strength and stiffness. 

Another great exercise to build tendon stiffness and power is repeated jumping at a relatively fast pace ideally in bare feet on a stable flat surface.   Like your ankle your foot and foot muscles are specifically designed to allow you to store energy in the foot muscles when you land and the reuse that energy to project more energy as you push-off. 

 It is key that you land ball of the foot first and then allow your heels to touch the ground before you rebound.    Start with very small jumps at a quick pace – done properly you will literally feel the stretch-shortening cycle and feel “springy”.   Slowly build up to being able to do this for 5 full minutes – it is harder than it sounds and you will notice your feet and calves both get tired at first!

If you have ever watched children in bare feet you will notice that they frequently spontaneously do this type of jumping because it feels good and teaches them to how to store and release energy from the Achilles Tendon.

Quercetin – Your Key to Minimizing Covid Symptoms?

 


Unless you live under a rock - you are hearing about the Delta Variant of Covid that is now the dominant strain of Covid causing infections.     Unfortunately, even vaccinated individuals can have “break-through” infections although the evidence is clear that these infections tend to be much milder with very low rates of hospitalization or death.

Whether you are vaccinated or not there are steps you can take to protect yourself and minimize the risk of serious infection.    Maintaining in ideal bodyweight, blood pressure, and exercising regularly can all lower your risk of serious outcomes.

Having a nutritious diet combined with targeted supplementation can also make a difference.   Having ideal levels of Vitamin D in your blood has been directly linked to significantly lower risk of serious outcomes – so get your D levels checked with a blood test and supplement accordingly.   Ideal D levels are incredibly important to your overall health and to your body’s ability to fight Covid.

Another supplement proven to help minimize the impact of Covid is Quercetin.   Quercetin is a bioflavonoid. Quercetin was initially discovered to enhance the antiviral effects of zinc by serving a zinc ionophore – meaning Quercetin enhances the transport of zinc INTO your cells where it can fight viruses.

The science on quercetin’s anti-covid activity quickly evolved further showing additional specific actions useful against SARS-CoV-2. Quercetin exerts significant inhibition on the binding of specific spike proteins to ACE-2 receptors, thereby blocking the ability of the virus to infect human cells.

Quercetin has also been shown to directly neutralize viral proteins that are critical in the replication of Covid.   It exerts multiple sites of inhibition of the virus.

In order to reproduce the antiviral effects, the dosage of Quercetin must be able to raise the level of Quercetin so that it can effectively combat the virus.   Regular Quercetin Supplements are not absorbed well and there is a high degree of absorption from one person to the next.

The great news is that there are more bioavailable types of quercetin proven to dramatically boost the amount of quercetin absorbed and in the blood stream where it can do its work.

Two New Clinical Trials Using Bioavailable Quercetin

Most importantly two new clinical trials showed dramatic results with using one of these forms of quercetin along with standard care for people infected with Covid!

The type of Quercetin used in these clinical trials was Quercetin Phytosome which is a patented form that combines quercetin with a liposome.  A liposome is a special type of carrier that chaperones quercetin into the body and cells.

In the first study it was shown that 400mg of Quercetin Phytosome produced statistically significant improvement in all clinical outcomes such as need and length of hospitalization, need of invasive oxygen therapy, and progression to intensive care and death.

The second study provided even better results.    The study involved 42 patients with early Covid who were given standard medical care alone or with Quercetin Phytosome at a dosage of 600mg per day for the first 7 days and 400mg for the next 7 days.

After 1 week, 16 of the 21 patients in the Quercetin group tested negative for Covid and 12 patients had all of their symptoms resolve.  In the group getting standard medical care only 2 out of 21 patients tested Covid negative and 4 patients had partial symptom improvement.

By 2 week all remaining patients in the Quercetin group tested negative for Covid while in the standard care group 17 tested negative, one tested negative by week 3 and one patient died by day 20.

The Three Forms of Bioavailable Quercetin


The key to getting results with Quercetin is that you MUST use one of three highly bioavailable forms to raise levels where they need to be to fight Covid.    The three forms of bioavailable Quercetin on the market are: 

 Quercetin Phytosome by Thorne – recommended dosage for effects – 600mg per day – 2 – 3 capsules

Quercetin LipoMicel Matrix by Natural Factors – 500mg per day – 2 capsules per day

Bioactive Quercetin EMIQ by Natural Factors – 200mg per day – 4 capsules

These supplements are all available on Amazon and both Natural Factors and Thorne produce supplements of the highest quality in direct compliance with pharmaceutical good manufacturing production guidelines so you know what you are taking!

As with all supplements speak to your physician first and those taking any medication should search for drug nutrient interactions with Quercetin before supplementing.   For example quercetin may amplify the effects of blood thinning medication so people on this type of medication should NOT take quercetin at all with speaking to their physician.
