4 reasons your muscles are cramping up

Are muscle spasm cramping your ride? There’s a reason for that… and a solution too.

Young, old, active and sedentary alike are all susceptible to cramps – and they can come when you least expect it – creeping up on you during an easy ride or disrupting a good night’s sleep.

“Muscle cramping is basically an over-activation or contraction of a muscle,” says pain management expert Dr Houman Danesh.

“And although it can happen anywhere, it usually occurs in the calf since that muscle uses the most energy in the body.”

But while it’s easy to know when you’re having a muscle cramp, it can be harder to figure out why you’re experiencing one.

We talked to Dr Danesh about the surprising reasons why you might be cramping.

Dehydration

“The way muscles are activated involves a balance of electric signals and ions,” Dr Danesh explains. “Dehydration changes the pool of signals. So changing that signal, the body doesn’t know if the signal is coming from the brain or just because there’s an electrical imbalance around the cell.”

With all this confusion, your muscles have difficulty processing the right signals. And that over activity results in pain. Luckily getting rid of this cramp doesn’t have to cramp your style.

Hydrate, hydrate, hydrate!

Holding a position for a long time

There’s nothing more annoying than having a crooked piece of art hanging in your apartment. Well, maybe except for that arm or back cramp you got while trying to hang it just right for an hour.

According to Dr Danesh, it’s common to get a muscle strain after holding a position for a prolonged period of time. “Doing something your body isn’t trained to do constantly activates a muscle and breaks it down a little bit,” he says. “That breakdown usually causes a buildup of lactic acid which can trigger to muscle to go into spasms.”

Luckily, this kind of cramp typically goes away with time. Give it a few hours, but if it’s interfering to the extent that it won’t let you sleep through the night, you should probably talk to a doctor.

Nerve compression

Some also refer to this unpleasant phenomenon as a “pinched nerve”.

There’s a series of nerves going all the way from your brain down your spinal cord, and according to Dr Danesh, “anything can cause a nerve to be pinched from a herniated disk to arthritis to putting yourself in a weird position, which will irritate the nerve.” (Don’t push those yoga poses if your body says no!)

“Thankfully the body is a miraculous healing system,” he says. Usually a regular dose of anti-inflammatory meds will relieve the pain. But again, if that first line of defense doesn’t get the job done in a few days, to the doctor you go.

Inadequate blood supply

Another possible reason for muscle cramps is an inadequate blood supply – which literally means you aren’t getting enough blood flow to your legs or arms.

“That’s usually due to a buildup of cholesterol in your blood, but it could also be due to a pinched artery by an ovarian mass or tumor,” Dr Danesh says, although he continues that this more serious cramping would probably be noticeable (a.k.a. not just your average cramp).

You should be on the lookout if you have high cholesterol and chat with a doctor.

Dr Danesh also says that if you keep getting a muscle cramp consistently at the same distance marker during training, that could also be a sign of compartment syndrome – which impedes blood flow – and you should see a doctor ASAP.
