Watermelon avoids aching muscles
If you consume a number of big portions of watermelon prior to a heavy training session today, you’ll have less issues with aching muscles tomorrow. According to nutritional experts at the Universidad Politecnica de Cartagena in Spain, this is since watermelon is a top quality source of L-citrulline [structural formula on the right].
L-Citrulline is a precursor of L-arginine, which in turn is a precursor of the capillary widener and efficiency enhancer nitrogen monoxide. Since the liver does not break down L-citrulline so rapidly, some sports researchers believe that professional athletes obtain more gain from L-citrulline supplements than from L-arginine supplements.
An outstanding natural source of L-citrulline is melon. One litre of melon juice – which you can quickly make yourself by chucking cubes of melon into a mixer – includes 2.3 g L-citrulline plus 58 g carbs.
So if L-citrulline supplements can assist professional athletes enhance their efficiency, can watermelon assist them too? That’s the concern the Spaniards wished to address. To do this they initially took a look at whether gut cells can take in the L-citrulline discovered in watermelon. The Spaniards utilized fresh melon juice for this, and likewise pasteurised juice.
They found that gut cells take in L-citrulline much better when it remains in the type of juice: unpasteurised melon juice was an excellent source. Obviously melon juice includes compounds that enhance the uptake of L-citrulline, and these are neutralised when heated up.
Control = L-citrulline; PW = pasteurised melon juice; NW = unpasteurised melon juice.
The scientists then provided active trainees half a litre of melon juice [NW], and got them to cycle for an hour on an ergometer. The trainees needed to do 30 2nd periods 8 times in a row. On 2 other celebrations the trainees consumed a placebo consisting of no active components [Placebo], or melon juice to which the scientists had actually included a number of grams of artificial L-citrulline [EW].
The melon juices decreased the trainees’ heart rate a little, however the result was not statistically considerable. What was considerable was the result on the muscle pain the trainees reported 24 hours after the effort.
Melon juice decreased the muscle pain. Natural juice worked about in addition to the juice the Spaniards had actually included additional L-citrulline to.
“This paper demonstrates the possible ‘functionality’ of watermelon juice rich in natural L-citrulline”, the scientists compose. “Future research should be focused on the minimal concentrations of citrulline required for reduction of muscle fatigue and other health benefits in stress, athletic performance, and cardiovascular disease. This amino acid could be supplied as watermelon juice or as products enriched in citrulline from watermelon extraction.”
Well. If you can’t pasteurise melon juice, melon-based practical foods are not likely to emerge quickly. Just items with a service life of years have any possibility of success in the unusual world of sports nutrition. Professional athletes will need to do it themselves with genuine melons.
The scientists were not moneyed by a melon-growers’ organisation, however by their university.
