so i can't find a solid answer online, was looking to see if anyone had any background on this. i work out pretty regularly, 4-5 times a week. i was doing cardio on saturday, doing sprints with a sled and weight on it when as soon as i was done i felt really light headed, almost dizzy. its not the first time its happened like this, but was the worst. i've noticed this before when i have tried to max out on bench press too. obviously when i'm straining myself is when it happens. i have a trainer but he isn't really medically trained....

is there anything to do to prevent this? i've read everything from eat more to rest to more sugar before? has this happened with anyone?

blood sugar is too low... eat more carbs before the workout or have a gatorade...

dont light up a cigarrette while doin the sprints


j/k

Yup blood sugar is too low. Have a banana right before you work out. The glycemic value is so high it's almost like just eating sugar.

its either blood sugar or how you breath when you are under strain. Try thinking about each breath you take when you are lifting heavy or if your heart rate is high while doing cardio. It happens to me from time to time on a heavy lift.

how long into your workout does this happen?

Id check your blood pressure too, but make sure to drink plenty of water or gatorade as PR_Glen said before/during workouts.

You want to be very careful as you could faint and end up hurting yourself. Would be worthwhile to talk to your doctor about it

I had it happen to me once and crouched down in case I actually passed out. In my case I think it was caused by slight dehydration - too much coffee and sodas, not enough straight h2o.

Dehydration can cause low blood pressure which raises your baseline heart rate, which only goes even higher as you exercise.

Happens to me with my breathing. But i focus on it much more now. When you're straining it is easy to forget to breath.

couldn't it be depleted glycogen stores? here's why i ask- 2 of my weekly workouts are fasted training, i don't eat for 16 hours before those sessions; but that doesn't cause me to have the above issue UNLESS my workout goes past a certain amount of time- after my glycogen stores are burned up.

PR_Glen

we should all be checking our blood pressure even if we don't have problems. There are no symptoms if that is high, you just drop dead without warning Good news if its high? Meds can save you with almost no side affects.

Scuba Steve, if you are pushing that hard that often you COULD just be hyperventilating and that can cause you to pass out depending on intensity but I would put more money on the low blood sugar we mentioned before.

ss, what sort of eating plan are you on currently?

tical

don't end up like this guy



one of the comments in that vid explains it nicely

The reason this happens is complicated. Long story short, bearing down and holding your breath while straining to the limits of your ability causes your blood pressure to skyrocket and your blood vessels to dilate to compensate. When he dropped it and yelled triumphantly, his blood pressure went back down to normal, but the blood vessels remained dilated. Suddenly a lot less blood is getting to the brain, which decides it's a good time for a nap. Right into the dumbbells.

dyna mo

signs of glycogen depletion: headache, fatigue, dizziness or weakness in the knees.

dyna mo

holy crap, did he just lift that using only his lower back? wow.

scuba steve

i thought it was the blood sugar, so i specifically ate a banana right before i went to work out. i'm also hydrating every 10 mins. it was outside, in about 86 degree weather, but its nothing i'm new to.

the sled sprints came at about 40 mins into the workout. when i do max bench its the first thing i do when i get there. i'd be surprised if its hyperventilating, i have a trainer with me that i would assume would point it out...

could i need just more than blood sugar, like one banana isn't doing it?

my diet is better than average but by no means hardcore. i cook a lot of my food, stay away from red meat except for maybe once a week, lots of chicken/fish, whole wheat if i do eat bread/pasta, try to stay away from processed sugars but i do indulge maybe once a week

i had my blood pressure checked actually 2 weeks ago at regular dr check up, 120/80, heart beat resting at 60. was told that is good for my age, 27. i don't think its that, but is there a way to check it during a workout?

another reason that could explain it: over-exertion.

WarChild

It could be, for sure. Typically though you'd expect to see other symptoms of this, but not necessarily.

increase your carbs during non workout times, off days etc, to load your glycogen stores up to the max, then if it happens again, you will know it's not a blood sugar/carbs issue.

dyna mo

yeah, just some food for thought/discussion eh. several different things could of added up to cause it a couple times. blood sugar is the most likely but that, to me, implies an overall food issue not just going into workouts with low blood sugar. more food for thought........

WarChild

So you don't experience the light headedness and dizziness until 40 minutes in to your work out?

You need more carbs pre-workout. The Banana is great simple carb, but mix it with a low glycemic value complex carb like oatmeal. Have a bowl of oatmeal with banana, or blueberries, before you work out. If you're really pushing yourself hard with max weights and THEN doing cardio afterwards, you can almost expect your blood to become glycogen depleted and that will cause the symptoms you're experiencing.

Listen to your body, it's telling you it's hungry. If you're doing heavy work outs you're going to need to supply heavy amounts of nutrients.

You say you're hydrating every 10 minutes. Are you sweating heavily and hydrating heavily? If the answer is yes, throw some electrolytes in to your water while working out or switch to gatorade.

ok cool, thanks war and dyna

going to try and get some carbs/extra sugar in before today, see what happens

scuba steve

not more than normal, no. i've always played sports, so i'm able to gauge off this. i alternate actually between gatorade and water, off and on

dyna mo

wc knows!

WarChild

Yeah more carbs in the day then.

Do you ever find yourself craving carbs at night? This is a big indicator for me. If I'm craving carbs at night, I know for certain I need more early in the day.

did it for a bit, wasn't worth the massive diarrhea that happened nightly haha

sounds like you workout pretty hard too eh, perhaps emphasis carbs on your workout days??

my current eating plan has me cycling carbs, i'll include a plate of pancakes on exercise days- 2 stacks! made a massive difference.

JustDaveXxx

Yes. This is one major factor.



This was another major factor that nobody thinks about and constantly forget when lifting heavy.



These were the 2 factors that made me dizzy and light headed during heavy lifting and squat days.



Also keep in mind if you are thirsty, you are dehydrated. Need to drink water before you get thirsty when you are at the gym lifting heavy.

gotta get more carb posts in this thread before the no-carb guys get here! ahahahahahah.

WarChild

The reason I doubt it's breathing is because he has a trainer. If your trainer doesn't notice fucked up breathing during at least the bench press while he's spotting, then he needs to be fired. So while it's possible, I'd say unlikely.

They say you should check BP at different times of day too and get some averages.

noxplode is just a fluff supplement, nobody needs that... If it has taurine in it then I think it would put your heart at risk too in my opinion...

very simple...

work on your anaerobic cardio more.. two types of cardio

aerobic and anaerobic

I know guys that can run marathons but can't roll 2 min on the ground with me....


it sounds to me more like a runners high ..... thats normal ... learn to love it and think of it as a freebie from god....


everyone is saying oh this and that check pressure this and that

blah blah


look if your not getting out of breath in the first 2 reps then your fine it's not a health issue....

go in the evening after work, saturdays early afternoon

good question, i'm able to run 5k in 22.30-24 mins, but i haven't tried to wrestle/spar with anyone. i think its overexertion though, happens when i max on bench too

just reading about the kenyan who won the boston marathon this weekend- averaged 13mph! finished in 2 hours 3 minutes. fuck!

DirtyDanza

not even wrestle or spar..

set your timer for 3 min

do burpies as hard and fast as you can..

im assuming you know what burpies are.. basicly squat thrust and updowns all in one..

see how you feel after words... see if you can recreate the same feeling...

id be willing to bet it's your anerobic cardio

we get "athletes" in the gym all the time that get very upset at themselvs ...

fucking 6% body fat... 6 min miles all day long.... but can't last 2 min cardio wise on the mats.....

the body needs to be able to perform with air and without is all it boils down to....

just by the sounds of what your saying that would be my guess if I were your trainer..

Low blood sugar will cause weakness. You'll actually feel weak and if you do enough sports, you'll be able to spot this feeling very easily.

Did you feel weak along with the dizziness, or just dizzy?

If it's just dizzy, then it's probably not blood sugar related. Your cardio could also not be as good as you think and you are outstripping the oxygen your body has available. If that is the case, I would suggest doing interval type cardio instead of just straight cardio. Intervals decrease the recovery time between efforts and increases the amount of blood pumped per beat. It increases overall pumping volume as well.

I like to eat oat mill with raisins, pumpkin seeds & a measure of protein powder. Gives me a good kick to start my workout. Also take Muscle Pharm Assault mix 20 mins before I start.

are you breathing? When you bench blow out of your mouth on the way up. When jogging try breathing in through your nose and out through your mouth. Focus on your breathing. DEEP BREATHING.
