Quercetine
In a randomized, double-blind, placebo-controlled, crossover study of a treatment group of healthy volunteers did not fit, but they were given 500 mg of quercetin to take twice daily. After 7 days in both the active and the placebo group were asked to cycle to the point that fatigue would allow no further cycle.
The results showed that quercetin group was able to continue cycling for over 13% more than those taking placebo.
While this is the first clinical trial increase resistance to study the effects of quercetin in humans, several previous animal and in vitro studies have indicated potential benefits in this regard.
Quercetin is a flavonoid natural gift in a variety of spices, fruits and vegetables. Onions and garlic are the spices that contains the largest amount of quercetin, while the apples, grapes (wine included) and the pears are fruits with high levels of the phytonutrients. Broccoli is the vegetable with the highest levels of quercetin and tea it is to get as much good publicity these days, it also contains high levels of the phytonutrients.
How exercise boosts quercetin resistance
While there may be other reasons, we know the effects of resistance that quercetin is the improvement is mainly due to its powerful antioxidant, anti-inflammatory, mitochondrial promoting properties.
The anti-oxidant activity: When we exercise our cells for long periods normal release higher amounts potentially harmful free radical compounds. While our body produces its own anti-oxidant protection that its production can not keep pace with the large number free radicals released during endurance exercise. This applies even more to those individuals who are unaccustomed to exercise. This is where antioxidants diet such as quercetin are important because they help internal antioxidants such as superoxide dismutase, glutathione, and others to address the increased the production of harmful free radicals.
The anti-inflammatory activity: Exercise is important as it is also a major cause of inflammation in the muscles, ligaments and other tissues, the longer the exercise period, the greater the inflammatory response. Plant compounds such as Quercetin helps to modify excessive inflammation, reducing tissue damage and allow the athlete to continue exercising for a longer time period.
Mitochondrial Biogenesis: Mitochondria are the cellular components responsible for energy production. During the exercise, such as muscle and other cells work harder, requiring more energy. Fortunately, quercetin and other compounds from plants have the ability to activate signaling pathways that stimulate the formation of more mitochondria. More mitochondria means more energy for the cell, so if you take quercetin can exercise for longer periods long time.
Although clinical trials using doses of quercetin, which are higher than those found in most diets, if you eat (or drink) foods that contain high levels of this compound will benefit from your exercise improve health promotion and other effects. The alternative is to take a supplement pure quercetin or a supplement that contains this important phytonutrients
