I would like to know on what difference is between pulse current and AC current

Does anyone have any suggestions?
Thanks in advance for any suggestions

In AC current, the electrons move back and forth along the conductor. Pulse current relates to DC current.

I would like to know on what difference is between Pulse current and + battery -, both are DC.

Do you have any suggestions?

Do you have an article on pulse current? We may have a different understanding about what it is. I want to make sure we're discussing the same thing

Thanks

I see now what you mean. This technology is called electromuscle stimulation (EMS). It works by sending an electrical impulse into a muscle group, eliciting a contraction. For a muscle to contract, the central nervous system will send an electrical signal through the body via neurons. Once this signal reaches its destination, the result is called an action potential. Once these action potentials build within the cells of muscles, the physiological effects result in a muscle contraction. EMS works by mimicking the action potential at a specific muscle group.

EMS uses the tradition DC current, where electrons follow the path of the conductor which leads back to the battery source.

When a neuron is stimulated enough, it fires an electrical impulse that zips down its axon to its neightboring neurons. This nerve impulse is called the action potential.

If EMS sends an electrical impulse to trigger nerve impulse, it requires to perform following tasks:

For Sodium-potassium pump, when every 2 potassium ions it pumps into the cell, it pumps out 3 sodium ions, it requires ATP energy for this process.

1) ATP attaches to protein with bound sodium ions and change to ADP
2) Extracellular potassium ions bind to exposed sites. Binding of potassium causes release of phosphate from protein and ADP transform back to ATP.
3) Phosphate release changes protein back to its original shape. Potassium ions move into the cell.

Since ATP > ADP > ATP, I would like to know on whether this process requires extra energy or not? what is the cost in term of energy during EMS exercise?

Do you have any suggestions?

None of that stuff happens with ATP, etc. The neutrons just act as conductors, overriding what normally happens when neurotransmitters activate neurons within the body

When EMS send an electrical impulse to trigger nerve impulse, I would like to know on how systolic and diastolic pressure are affected by EMS, for example, Pulse wave through the arteries caused by the stretch and recoil of the aorta, do EMS effect the pulse wave as well? If that is the case, would increasing pulse wave also increase systolic and diastolic pressure?

Think about what happens during electrocution because that's essentially what's happening here. All muscle fibers are tense and contracted during electrocution. That causes surrounding blood vessels to constrict, increasing blood pressure momentarily.

Let assume heart rate is 80 per minutes, if EMS at 70 pulse per minutes, would EMS's 70 frequency interrupt the heart's 80 frequency? since the heart muscle's tense and contract are also controlled by nerve impulse as well.

The pulse frequency isn't important.

Regardless of its frequency, the affect on the body is the same. They increase pulse frequency to prevent the nerves from overheating, causing permanent damage.

Could you please describe more on why and what frequency affecting on the body is the same?

The frequency at which the pulse is transmitted to the body is programmed to prevent your nerves from overheating.

Here's what happens to someone struck by lightening.
