FORUMS > Cardio Training Forum Rules

I often get dizzy/faint feelings when doing my cardio workout which is really annoying. I think I drink enough water so I really don't know why this happens.

try eating a banana 20 mins before could be potassium or your electrolytes. By the time you feel thirst it is too late to replenish.

Peace

Cool maybe I'll try that and a gatorade and see what happens. Thanks.

Are you doing cardio on the same day as weight training and if so, in what order? It could be a glucose issue. Give us some more info. Nothing's worse than dropping in the middle of cardio. Be careful.

you're obviously not eating enough. make sure you get plenty of carbs and some protein about 2 hrs before you train. and take a protein drink directly after. you need to look at your diet hippie. being vegan/veggie is fine but you must make sure your getting enough calories and supplements.

protein has been shown scientifically to satiate the body for longer.

uva its interesting that you mention that. I do some cardio first, than lift than end with some cardio. I do this because I have most energy at the start and want to make sure I get that part over with. But yeah I think the fact that I do that it raises my heart rate and I kinda just stop suddenly.

I had this problem and eventually went to the doctor for it. I had been eating super healthy and had been doing a lot of running. My problem was more limited to when I stood up. My doctor said that I needed an increase in my sodium intake. Basically, electrolytes. Some of us need more than just water sometimes.

I get that after doing leg presses and when a lover does poppers. I hate poppers.

I used to get that, which put me off any form of exercise for a few years. Then I went to the doctor, who told me that it's a sugar (glucose) issue, and even told me to pop a Mars bar when I feel faint (I think MikemikeMike's advice is better; eat a banana). Apparently some people are more sensitive towards blood sugar fluctuations.

You could try one of those sports drinks to keep you topped up during your cardio routine, or make your own. This is from this month's Men's Health (UK edition):

750ml water
250ml orange juice
2 tsp sugar
1 large pinch of salt

I've not tried that, so I'm not sure how well it works.

Yeah, as above, I guess it's probably your diet. I also get a bit of a headache sometimes, I'll try eating a banana too, hehe! The worst dizzyness I get is when doing hyperextensions, but I guess it's simply coz I'm bobbing my head up and down the entire time.

Not to scare you or anything, but have you seen your doctor about this? You're much too young to be feeling faint after 30 mins of high-intensity cardio.

Also, I doubt that anybody would advise you to sandwich a strength-training session between two different sets of cardio! Not even I do that, and I've been doing high-intensity sports (kick-boxing, cross-country, wrestling, competitive swimming) for years!

I'm also dealing with dizziness right now. Although mine is mostly positional related. I tend to have problems on the decline bench. Sometimes when i lean back i get really dizzy, sometimes i can sit up and it's over quick, sometimes it's not and my workout is done. I went to an ear, nose throat doctor, thinking it was all related to my semi-frequent sinus infections messing with my inner ear.
Turns out after a CT, and MRI (gotta love insurance, those 2 were like $3200 combined, but nothing from me) I have herniated cerebral tonsils. which basically means the bottom of the back of my brain is starting to slightly squeeze out the hole where the spine comes out. Certain things cause it to bump into bone, causing dizziness, plus it can affect the flow of the fluid around the brain and spine. My balance has also slightly affected.
I've got an appointment with a neurologist in a couple weeks, so we'll see how that goes. the ENT sounded like i might just have to deal with the dizziness. There is surgery to enlarge the opening in the skull, but it doesn't sound like fun.

And Muttskins, have you tried "spotting" like the ice skaters do during a spin, find a fixed point to look at while doing the hyper extensions. A few feet in front of me tended to work best. that helped me some with getting dizzy during those.

I had this problem a couple of times. In my case, it was that I hadn't eaten much (or anything) before working out. It sucks.

If you have something small like, two or three hours before you exercise, it'll probably help

Sugar levels maybe?

Without getting into a hundred other questions let me ask this - how warm is your gym?

If you are trying to do cardio (or serious weight lifting) in a poorly ventilated area, that could certainly contribute to making you feel dizzy.

I noticed no one else brought this up, and I'm always surprised that people rarely think of ventilation as a possible cause of dizziness. High temperature, humidity, lack of oxygen, etc., combined with physical activity, can certainly bring on what you are describing.

I think I posted to the forums here a few times last summer after I moved to NYC, because I found the air conditioning pathetic in most gyms in this city. With my hummingbird metabolism, I can't even THINK of doing any serious physical activity with temps much above 73. (Suffice it to say that I'm not a fan of summer).

In fact I recently left Equinox because even at their price (and even in the dead of winter!), I found most of their gyms had serious issues with temperature, humidity, and just plain stale air. It amazes me that people seem so willing to shrug off temps that can approach or even pass 80 degrees. I've learned to be especially aware of this because of my metabolism, but not everyone things as I do.

Long story short, if you are trying to do serious exercise in a humid, 80 degree room with recycled air... That could definitely be the reason.
