Beets boost athletic endurance.
Nitrates and betalains in beetroot juice may boost athletic performance.
Nitrates increase muscle blood flow and oxygen, according to a 2017 systematic review. In a study, cyclists took either 100 mg of beetroot concentrate or a placebo daily for a week. The placebo group had lower exercise efficiency and blood flow than the beetroot concentrate group.
Why do I need nitrates in my diet?
People think that eating nitrates and making NO afterwards are important for how humans work. The direct catalyst for vasodilation is nitrate.
Vasodilation, which widens blood vessels, helps the body deliver oxygen-rich blood to vital organs.
As a result, vasodilation is increased, which helps the body transport nutrients like glucose and fats. While NO affects many bodily functions, including muscle contraction, glucose sensitivity, wound healing, blood flow, blood clotting, haemoglobin delivery of oxygen, and mitochondrial function, it also aids in immune system regulation, inflammation control, and even penile erectile dysfunction!
The recommended daily nitrate intake is 3.7 mg per kilogramme of body weight, but the average person only takes 75 mg. So, for example, a 50 kg (110 lb) athlete should consume 185 mg daily, while a 75 kg (165 lb) athlete should consume 277.5 mg daily.
What makes nitrates suitable for athletes?
When we work out, train, or play sports regularly, we get better at the same level of intensity. This makes us feel like we are working less hard. It considers mechanical, neurological, and physiological processes.
It has been shown that eating foods high in nitrates makes muscles work better, so less work is needed to get the same result. In addition, it implies that you can improve your athletic potential through exercise.
Everyone wants to exercise longer and harder at the same intensity without getting tired when it comes to sports with an aerobic component. It has been shown that taking nitrate supplements reduces the amount of phosphocreatine (PCr). And adenosine triphosphate (ATP) is needed to contract muscles at the cellular level. It means that less PCr is required to do the same work.
So, nitrates improve the muscle's ability to contract and the efficiency of oxidative phosphorylation, a process that cells use to make energy.
In other words, you can work more efficiently by exerting more contractions with less energy. In addition, studies show that plasma and salivary nitrate, nitrite, and nitric oxide levels increase by more than four times after consuming more dietary nitrate for five to seven days straight.
Nitrate-rich supplements with 400 mg of nitrate have helped people walk, run, row, cycle, do repeated sprints more efficiently and take in more oxygen.
All age groups studied, including untrained men, trained men and women, healthy men and women, and patients with peripheral artery disease, all showed benefits.
Nitrate supplements benefit people of all ages and genders and help them live healthier lives. However, the results might be less impressive if you are an elite or highly skilled athlete. For example, research on professional cyclists has shown conflicting results. However, their bodies are in better shape, making a lot of endogenous nitric oxide on their own.
Beets have a strong nitrate presence. Beets are vegetables with the highest global nitrate content (and beetroot powder extracts). Having betalains, which are strong antioxidants, around has many advantages. However, it also contributes to the deep red-purple colouring of beetroot. Beets contain antioxidants and micronutrients, especially inorganic nitrate, potassium, betaine, sodium, magnesium, and vitamin C (NO3).
More than ever, it's crucial for our community to be healthy. According to studies, nitrate-containing foods or vegetables can benefit the body even after just one serving, and this advantage grows as consumption increases.
What beetroot dosage will best improve your athletic performance?
The best dose for athletes to get the sports-related benefits of nitrate or beetroot powder is higher than what is needed to get only small health benefits. Studies on the best dietary nitrate to boost athletic performance show that 400 mg is the magic number.
Studies show that taking 400 mg of dietary nitrate supplements for seven days improved subjects' athletic performance.
It raises the body's nitric oxide (NO) levels to their maximum, which can improve time to exhaustion and VO2 by reducing the amount of oxygen needed for the same work, peak power output, time trial performance, and repeated sprint efforts.
Another crucial thing to remember is that peak NO levels will happen two to three hours after ingesting a food or supplement containing nitrates. Therefore, if you need your body's NO levels to be at their highest during your sporting event, try to time when you eat the nitrate-containing food or supplement to suit.
For best results, don't rinse your mouth.
Remember that an active transport system concentrates nitrates in your saliva when you drink beetroot juice or eat other foods or supplements containing nitrates. In saliva, nitrate concentrations are at least ten times higher.
Up to 25% of dietary nitrates are thought to be salvaged during enterosalivary circulation. Nitrates are changed into nitrites by the bacteria in the mouth, which are then changed into nitric oxide.
Because of this, it's best to use only certain mouthwashes right before eating nitrates. Studies on people and animals have shown that mouthwashes with chlorhexidine can raise blood pressure and stop the body from reacting to nitrates. In addition, it shows how critical oral bacteria are for nitrate bioactivation.
It is not to say that you should not brush your teeth after taking a nitrate-containing supplement or leafy vegetables; we're just saying that you shouldn't use mouthwash first.
Not just for race day: beets
There is currently a trend in nutrition that is moving the emphasis away from performance and towards something more health-focused.
Along with regular exercise, eating nitrate-rich foods should be a disease-prevention priority.
So, if you're thinking about performance when deciding whether or not to eat products with beets, think about the health benefits first.
