Popeye has taught us this since we were children: Eating spinach, which contains iron, helps build muscles and make you stronger! In fact, a few years ago, some scholars had denied the legendary sailor, stating that - based on some experiments - the amount of iron present in spinach was not enough to strengthen the muscles.

Arm wrestling he has taught us this since we were children: eat spinach, which contains it iron, helps to enhance the muscles and to make you stronger! In fact, a few years ago, some scholars had denied the legendary sailor, stating that - based on some experiments - the amount of iron present in spinach was not sufficient to strengthen your muscles.
But no! These precious vegetables contain a lot inorganic nitrates which would allow us to significantly improve the capabilities of our muscles; and the effects are seen immediately after eating them!
To support this hypothesis comes a study - also published in Cell Metabolism - conducted on a group of volunteers tested at the Karolinska Institutet in Stockholm and led by Eddie Weitzberg. According to the experiments carried out by Dr. Weitzberg, by eating a portion of spinach before riding the exercise bike you can obtain unexpected results: pedaling is immediately less tiring, because nitrates have the power to reduce the need for oxygen to feed the muscles.
The volunteers who underwent the experiment in fact, - just after three days of spinach-based nutrition (or beets) - once they got on the exercise bike they demonstrated one greater muscle efficiency and less energy expenditure.
In short, all that remains is to swallow spinach and that's it; better if fresh and zero kilometers of course!
