Section One – why are functional knees one of the most important factors in your health?
There great news about recovering the capabilities of your knees, if you are willing to follow the slow and boring path to recovery. Before we get to that -what makes your knees so important for your health – and it is not the reasons you think!
People are often surprised to discover that knee problems can lead to an acceleration of the problems of “aging”. It is obious when you think about it.
Your Knees Are Part of a Vital Link In Your Body’s Circulation System
You most likely think of your knee problem as just the pain, or the ache, or the annoyance of not being able to do things you really would like to do. Maybe it is the sleep disturbance. Maybe it is because you have to take pills. Maybe you are just waiting for it to get bad enough for an operation.
What could be more important than pain and inflammation? Or being unable to do things? The answer is related to ability to move. The answer is that:
Without Knee Function You Begin To Stop Using An Absolutely Vital Part Of Circulatory System Called The “Foot and Calf Pump”
A key part of your anatomy is called the “Foot and Calf Pump“. It is known also as the “Venous Muscle Pump“. That does not sound too impressive, but after we talk just a little about how your body moves fluids – you will see how important it really is.
First, you already know that your heart pumps your blood in pipes called “arteries“.
Arteries come FROM your heart and TAKE blood to all parts of your body. As the arteries get closer and closer to your muscles (for example), they branch out and get smaller and smaller. When they reach your muscle the pipes are extremely small, so that the gases can move easily from the blood in the pipe to the muscle cells.
Past this point – blood is transported AWAY from the muscle in pipes called VEINS.
The thing about veins is that the blood is no longer moved by the pumping of your heart as it is taken away from the muscles.
So how does the blood in your veins get back to your heart and lungs again?
One source of movement is BREATHING. As your lungs expand and your diaphragm moves they create a suction force that helps your veins PUSH that blood back toward your heart. Pretty cool!
The other way that your blood is pumped in veins is when your muscles move. Your muscles are designed to “spurt” the blood in your veins when you use them.
Again, very cool. But here is the problem you are starting see. The upper parts of the vein flow of your body is well serviced just by breathing. It is not very far to pump in the upper body, and some parts it is a downhill flow so gravity helps too like the blood from your head, neck and shoulders.
But. What about the blood that has gone right down to your feet?
That blood has a long way to go in your veins, and it is all UPHILL unless you are lying down.
Your SECOND HEART?
The pumping of your leg muscles, especially your calves, is so important it is called your “second heart“.
This heart only works when you take a step. Your body weight then “squeezes” the veins in the bottom of your foot. Then you lift your heel and your calf muscles then spurt the blood into and up your calf. And each step pushes that blood further up your legs, through your thighs and up through your guts to your (first) heart.
This is amazing! The blood in your VEINS from the lower half of your body is not moved by your heart, but by the action and pumping from the motion of your feet! While this is an awesome design – you can see that the circulation of your bottom half RELIES on the movement of your feet and ankles.
And those pumps only work when you MOVE the muscles.
All the muscles do some of this work, but the most essential is the FOOT AND CALF PUMP.
If you do not use this sufficiently, the blood will GET STUCK in your lower body. The veins will over time fail to cope with that overflow. The “valves” will blow and leak. You will see swollen and varicose veins, and purple stains on your skin. Your legs will ache. The waste products from your muscles will not be cleared and will hang around – causing release of inflammation. The muscle, joints and other cells of your legs will not be able to access the oxygen and nutrients they need for maintenance.
Without sufficient movement, you will have a “swamp” starting to form because your “second heart”, your foot and calf pump, is not in play.
Also in many people your body will try to help by working your heart harder and squeezing the blood pipes. Your blood pressure will be messed up.
This is sounding pretty bad, but there is good news coming! Although first we need to cover just one more important factor.
It is about another bodily system that has to be drained, called the “lymphatic system”.
Without Pumping Movement of The Foot & Calf Pump – Your Lymph System Also Becomes Swampy
There is another circulation system that runs alongside the VEIN system, which also relies on the Foot and Calf Pump.
This is called the “Lymphatic System“.
The lymph system is a group of organs, pipes and tissues that both keep a healthy balance of fluids in your body AND protect you from infection.
Lymph is a watery fluid that washes around all your cells and organs. This is an amazing system, but all we need to know right now is how it moves through our body, and what happens when the Foot and Calf Pump is under-used.
Every day you produce about 20 litres of PLASMA whic is a special component of blood. Plasma both delivers nutrients to your cells AND cleans up all the waste that is produced. Most of the plasma goes into the VEINS to a get a lift back to the heart.
But about 3 litres of the plasma is collected by the LYMPHATIC SYSTEM – and it is then called LYMPH. The lymph system has a network of small pipes becoming larger – just like the VEINS. These lymph pipes move up your body meeting at “Lymph DUCTS” and eventually empty into some large VEINS way up in your chest.
That was a little complex, but you now know exactly why pumping your Foot and Calf Pump regularly is so important.
And you cannot use your legs if your knees don’t let you…
In simple summary: Your body is designed for you to MOVE your feet, ankles and legs almost constantly so that the blood and fluids can get pumped (against gravity) to where they need to be.
And that’s why anything that reduces your movement of your ankles and legs (like chronic knee problems) is a very serious threat. Your entire quality of life depends on the movement of this part of your body.
