    cramp, and then relaxing and being very careful not tense the muscles involved returns the

    so i have had this problem. once in a while but for the last couple years, ive noticed on the longer and higher flights it gets worse.

    i asked a buddy who is a fancy surgeon about this. He laughed at me......."get your ass to the gym, old man" was his response.

    he said this is very typical when you are in one position for hours on end and lack of circulation is what is really going on.

    today, i took my GF to an outpatient facility for a minor surgical issue. while prepping her, they put these inflatable calf sleeves on her.

    i asked what these were for, and they informed me, much like when they take your blood pressure, they inflate/deflate squeezing the legs helping with circulation.

    then i wondered....why not try this in the glider? sure enough....a quick search found all sorts of these things on amazon.

    obviously not a replacement for the gym and cardio health.....but hey...why not give it a try?

    I occasionally have cramps in the sole of my feet when sleeping. I have found that pinching the upper lip firmly for 30 secs then releasing solves the problem - apparently a acupuncture pressure point. In any case, it works for me.

    His analysis doesn't explain why many of us, including me, get the same cramps while
    sleeping at night; also, I am at least as fit now as I was five years ago. The IPC
    (intermittent pneumatic compression) device is interesting, but too cumbersome to use in a
    glider.

    I've had a few people tell me that a shot glass of pickle juice helps with night-time leg cramps. Something to do with the salt/electrolytes in the pickle juice that helps prevent this.

    I get these cramps as well after long flights, sometimes on short flights. I get them in both cold and hot conditions.

    I started getting cramps in my new ship. I never got cramps before. Slight positional change?
    Perhaps we don't realize how tense we are up there flying a plane with no engine. My entire leg can get involved with moving the rudder rather than just using my calves and foot muscles. I seem to do better when I keep reminding myself to relax all my
    muscles. No tension!

    I actually reconfigured my panel to allow for more leg movement to massage out the cramp when they come.

    Wouldn't eating actual pickles be the same as a shot of pickle juice? Probably gonna smell up the cockpit for awhile if you spill some pickle juice.
    I'll try that lip-pinching technique next time.

    It really can be scary when your foot is completely locked up.

    The first two flights this year, I had severe leg and foot cramps after 3 hours of flying.
    The next four flights of 4 to 6 hours, no cramps. Was that due to the 125mg of magnesium
    and the 20 oz of diluted Gatorade I had before each flight? It's too soon to say, but I'll
    continue using both for two more flights, then stop using one of them to see if the cramps
    return.

    I did try knee-high socks on one flight - still had the cramps - so they don't seem to be
    a solution for me.

    I had leg cramps for many years - mostly at night, but also when flying. I was recommended foods high in magnesium and potassium rather than supplements and found that it did work for me.

    The DVT was a separate issue - a combination of positional immobility, dehydration, oxygen starvation and an inherited genetic mutation for thrombophilia - basically economy class syndrome in a glider!

    Recently a fit, 30-yr old who was a passenger in a glider being flown in the Seniors suffered from serious dehydration and his muscles seized up. The pilot landed shortly thereafter and the passenger was met by an ambulance that put him on an IV to get
    him rehydrated. It was scary for all involved. Coincidentally the next day's safety meeting featured a pilot who was a nurse anesthetist who described the dangers of dehydration and the physiological processes that body undergoes when it doesn't have
    enough water and electrolytes (your organs shut down). Bottom line folks: stay hydrated and drink your watered down Gatorade mixture in the air. You need the electrolytes. For those worried about extra sugar intake, Gatorade makes zero calorie options.

    Low potassium is a prime cause of muscle cramps, and Gatorade has very
    little potassium. You're much better off drinking milk if potassium is
    a problem.

    The professionals have given some good advice above. I'm an internist and I've had cramps also. In addition to the advice about maintaining fluid/electrolyte hydration, wiggling, stretching, I"d add
    - stay physically active, as toned muscles seem less likely to cramp in my own experience than flaccid, deconditioned ones.
    - Statins for cholesterol are possibly the biggest source of muscle cramps at and beyond middle age in the West. I couldn't tolerate any statin despite severe cramps, even with normal doses of QoQ10, but after my heart attack and stent, my friend
    Armistead, a diabetic with the same need and problem recommended *Kirkland* brand *300 mg* CoQ10 twice daily. No cramps since, and tolerating a statin well, with cholesterol <100 mg/dl

    It is interesting that this sports drink touts the sodium in it for cramp avoidance, and
    not the potassium and magnesium (which it also contains) other posters have suggested/recommended for cramp avoidance. This article mentions insufficient calcium (and
    magnesium) as a potential cause, so is it calcium, magnesium, potassium, sodium or? Maybe
    it's one or two of those for each person, but which one(s) vary between people.

    A common issue in all the articles and advice is dehydration, so that might be the best
    place to start. My levels of calcium, magnesium, potassium, and sodium are all in the
    normal range, so perhaps my problem is primarily dehydration, even though I think I'm
    getting enough to drink before a flight. Two more flights without cramps, and I'll stop
    taking the magnesium, but continue swilling the diluted Gatorade. If that's all it takes,
    great!

    Maybe it's one or two of those for each person, but which one(s) vary
    between people.

    A common issue in all the articles and advice is dehydration, so that
    might be the best place to start. My levels of calcium, magnesium,
    potassium, and sodium are all in the normal range, so perhaps my problem
    is primarily dehydration, even though I think I'm getting enough to
    drink before a flight. Two more flights without cramps, and I'll stop
    taking the magnesium, but continue swilling the diluted Gatorade. If
    that's all it takes, great!


    With the problem showing up in early season flying in the NW, I would
    think dehydration or electrolyte depletion is not a likely candidate.

    Since this first showed up several years ago, does it correlate with any medication changes? Drugs can and do have significant side effects,
    contrary to what you might have read here.

    Low potassium is a prime cause of muscle cramps, and Gatorade has very little potassium. You're much better off drinking milk if potassium is
    a problem.

    "An 8-ounce bottle of the original, fruit-flavored, ready-to-drink
    Gatorade has only 37 milligrams of potassium. Even by the standards set
    by the National Kidney Foundation, this is a very small amount of
    potassium. By way of comparison, 8 ounces of nonfat liquid milk have 382 milligrams of potassium."

    The link you posted sez: Certain dairy products, such as milk and

    Can you explain what the source of your "NO!!!" comment is?

    It is interesting that this sports drink touts the sodium in it for cramp avoidance, and

    I don't ever have cramps in my calves until get into a glider. This normally occurs early in the season. It seems to dissipate as I fly more often. This suggests that there is an acclimation process at work. My glider buddy (who is an ER Doctor)
    pointed out that the cramps could be caused by the seat position and my parachute/cushions pressing on the bundle of nerves in my lumbar region. I rarely get cramps in my ASW 20, I frequently get cramps in my LS3, I get unbearable, unrelenting cramps
    when I fly the club Grob 103. All of these ships have different relative seat positions. I am diligent about hydration before and during flight and most of the time these cramps occur while on tow. I understand that there are a multitude of reasons
    why we cramp. I suspect that our "nest" of cushions and parachute may have something to do with the problem. Keep experimenting with your comfort in a glider.

    I don't get "crippling" cramps, but I have noticed that early in the season, when I am trying to concentrate on not screwing up, I tend to put excessive pressure on the rudder pedals. This results in pain in my calves and ankles, which eventually could
    lead to muscle spasms or cramps. Some of this has to do with the "unusual" angle of my feet; twisted inwards, toes pointed with stress on the muscles that have not been exercised in this position over the winter layoff. As I get more comfortable during
    the season, I can concentrate on relaxing the pressure, flexing my ankles and legs as much as possible and after a few flights, the pain goes away, or doesn't even occur. I also started taking some advice from some of my friends who are rock climbers.
    They recommended bananas as a great source of energy and potassium, so I sometimes have one before launch. YMMV

    Bananas are supposed to be a good preventative and/or remedy for muscle cramps. High in potassium and magnesium. Also manageable in-flight food.

    That was my error. I reviewed my notes, and I've occasional cramping for 10 years or so,
    but this year, they were more severe and almost uncontrollable, instead of just a nuisance.

    I quit drinking milk several years ago. Milk is fortified with vitamin D which is essential to the absorption of calcium. After about eight years I found myself with a number of issues, including nerve pain especially in my legs, due to calcium
    deficiency. I eventually tried a Caltrate 600D which had profound effects after 20 minutes with regard to the nerve pain relief and continued on a course of those and supplemental vitamin D, all with positive results. You can overdue it, so periodic
    blood work is essential and adjusting intact to keep the levels in range. The key was probably the vitamin D as I still ate cheese, yogurt, and cottage cheese, just no milk, and was probably not eating enough of vitamin D foods. Hydration is also
    essential and other pilots have mentioned less tolerance of heat with aging. I've always liked diluted Gatorade.

    For some years I've preferred the taste of IsoStar Lemon to Gatorade
    because its less strongly flavoured and not as sweet, but YMMV.

    IIRC it and Gatorade became available at around the same time, but
    Gatorade is probably easier to find in the USA.

    The Mayo Clinic says (https://www.mayoclinic.org/diseases-conditions/muscle-cramp/symptoms-causes/syc-20350820):

    "Mineral depletion. Too little potassium, calcium or magnesium in your diet can contribute to leg cramps. Diuretics — medications often prescribed for high blood pressure — also can deplete these minerals."

    Best talk to your doctor about the situation since medications you are on can affect cramps. All of the sites I looked at recommended exercise, massaging and proper hydration to prevent cramps. Once in the cockpit exercise and massaging are not possible.
    Not one recommended taking mineral supplements, but it couldn't hurt. Here's one that contains all three:

    Eric,
    I've fought leg cramps for over a decade. Caffeine and alcohol
    exacerbates the problem (dehydration). I've gone to decaf coffee
    (sigh....) and no soda's with caffeine. I severely limit alcohol
    consumption during the flying season. I usually drink at least 28oz
    of Power-ade / Gatorade before a flight (sometimes more). Lastly,
    like Hank commented, magnesium really helps. I now take about 125 mg
    before bed for leg cramps at night. More and the negative effects
    kick in. YMMV.

    While the Mg and careful hydration management helped my leg cramps,
    come to find out the main culprit was a calcium deficiency. I did a
    minor amount of research and one of the main symptoms of calcium
    deficiency is regular leg cramping. I haven't drank milk in decades
    for no particular reason (no lactose intolerance). After a few
    glasses, bingo! No leg cramps. I tried calcium supplements and they
    work as well.
    What a relief not to worry about cramping after all these years.
    Craig

    adjusting my chute leg straps has helped a TON.

    not one cramp this year.

    what i found is when i put my chute on and adjust it for comfort, it was too tight in my seating position and slightly cutting off circulation.

    what a difference.

    I get the occasional middle of the night calf muscle cramp which has to run its coarse - about a minute. Hurts

    This also happens when applying rudder in the ASW-27 but not the Duo. I can feel it coming and stop it by letting off the rudder and accepting the sideways yaw string. Full rudder in the 27 requires a much more pointed foot/extended toes than the Duo.
    It may help to rerig the rudder peddles so that they are tilted back more at the top and thus require less contraction of the calf muscle?

    I have a similar situation in ASH26E (where I get cramps) vs the Phoenix (where I don't get
    cramps). Something to try.

    KS is exactly right and making the same point that I did on 2nd April. The great majority of calf cramps in gliders can be prevented by avoiding pushing your foot into the downwards-pointing position in which the calf muscle is fully contracted. Even
    if (like me) you are taking a drug such as a statin that makes cramps a bit more likely, they won't happen when the calf muscle is in a slightly or fully stretched state. Same principle goes for cramps in bed and for cramps in other muscles such as the
    quadriceps. If anyone is getting completely spontaneous cramps irrespective of position because of dehydration or medication or whatever they ought to get on the ground asap and sort out the issue before flying again.
