Role Of Calcium In Muscle Contraction

When you eat plenty of spinach, parsley, kale, or other green leafy vegetables, you provide your body with nitrates that make your mitochondria work better and cause you to need less oxygen during your workouts. In other words, you can work out more comfortably, without feeling as though you are gasping for breath.

You'll also have more energy as you go about the rest of your day, but I suspect you'll notice that energy the most during your workout!

You can't reproduce the effect of eating a big green salad by taking a supplement (in case you were thinking of it!). Nitrates in food need to be processed by bacteria in your mouth in order for the body to make efficient use of them. In fact, the bacteria in your mouth play such an important role in processing nutrients that scientists are now speculating that powerful antibacterial mouthwashes could block the effects of green leafy vegetables. Green Leafy Vegetables and Glutamine

Green leafy vegetables are also high in glutamine, an amino acid that is often taken by body builders as a supplement. Amino acids are the building blocks of proteins, and protein helps the body to build muscle mass. Believe it or not, green leafy vegetables are fairly good sources of protein, though you'll want other protein sources in your diet as well. While glutamine can be supplemented, you will get other benefits, such as the effect of the nitrates on your mitochondria, not to mention the fiber in your vegetables, if you get your glutamine from dietary sources, such as parsley, spinach, and asparagus.

However, if you really don't care for salad, there are alternatives. One is to juice your greens in a smoothie.
