If I use a pedal exerciser, my legs need to actively push the pedal. However, if I attach my feet on the machinery pedal, and let the machine rotates, my legs are still moving. I call that "inactive exercise".

enter image description here

Sure, the muscle doesn't work out because I don't spend energy, but the lymph does move in back and forth in it the system. As I know, the immune system needs the lymph to move because that's how white cells can escape the blood vessel to protect the body. Massage is one way to stimulate the movement of lymph.

So, would my immune system (and my health in genera) have equivalent results as it has if I really put my effort to do exercise?

  • Question includes some major errors with regard physiological functions. Lymph does not move if there is no muscle contractions in the legs: onlinelibrary.wiley.com/doi/10.1111/j.1469-7793.1997.233bf.x/… – arkiaamu Aug 5 '15 at 15:46
  • I haven't read all the paper but does it explain why massage does help lymph moves? – Ooker Aug 5 '15 at 15:58
  • "the propulsion of the lymph in skeletal muscle is dependent upon the external compression of the lymphatics (Refs 1&2). This compression can be produced by arterial vasomotion (Ref 1), or by muscle fibre deformations (Ref 3)." Considering massage as "external compression" massage could help in lymph moving. – arkiaamu Aug 5 '15 at 16:05
  • would inactive exercise be considered as "external compression"? – Ooker Aug 5 '15 at 16:08
  • while "inactive exercise" there is no muscle fibre deformation, so definitely no – arkiaamu Aug 5 '15 at 16:09

Basically every movement you make uses energy. The exercice on your photo defenitly uses a moderate amount of energy depending on speed and time you workout. Simplified your lymph moves with every movement, not only when you use your strength; in a healthy body(no heart or vessel disease) it actually moves without any movement. The white blood cells need no movement to 'escape blood vessel', but true, your immune system works better with proper lymph drainage. (simplified)

To answer your question: In assumption you are a 'typical' more or less healthy person, yes, it will be good to exercise (not because of lymph movement though). Every workout you make, even if it is just going round for an hour, cycling or anything else, will improve your health.

Note that 'too much' may do more harm than good.

  • I have major concerns regarding this answer (as I had with the question). References are definitely needed. For example, this is very strong simplification: "your immune system works better with proper lymph drainage". "will improve your health" Do you mean that the improvement in health is due to better movement of the lymphatic fluid, if so, references definitely warranted. – arkiaamu Aug 5 '15 at 15:50
  • I assumed the author may not look for a too intricate answer. Thats why I added a "simplified". The correct answer to this would be too complex. To give you some references on the importance of lymphatic system see this review ncbi.nlm.nih.gov/pmc/articles/PMC3780287, search for comlications of lymphedema to find articles like that ncbi.nlm.nih.gov/pubmed/12162204. – SalkinD Aug 6 '15 at 18:13
  • I'm sorry that I didn't receive the notifications. I'm still not sure if your answer is against or agree with the "inactive exercise". – Ooker Aug 20 '15 at 18:18
