Cutting Edge Nutrition

Just a few many years in the past, endurance sports activities nutrition was dominated by two essential manufacturers of brightly coloured sports activities drinks and some forms of old-school power bars. Walk into any native operating store or big-box sporting items retailer as we speak, although, and also you’ll discover a dizzying array of choices. What’s driving this? Athlete demand firstly. If it’d enhance general health and efficiency, many people will attempt it.

“We know we are working our bodies hard, and endurance athletes are always looking for an edge,” says Lauren Antonucci, a medical nutritionist and authorized sports activities dietitian based mostly in New York City.

The different important driver behind this burgeoning business is the evolving science. Even probably the most vigilant sports activities nutritionist would wrestle to maintain up with the reams of latest analysis being revealed. As scientists study extra about greatest practices for fueling and hydration, nutrition corporations are working to maintain up by offering athletes with the newest and biggest.

Here are a number of the most fascinating science-backed endurance sports activities nutrition tendencies to regulate this yr.

  1. Researchers are arising with new options to crush cramps.

For many years, athletes have been informed to load up on bananas and down sports activities drinks to battle muscle cramping. Studies carried out by Harvard neurobiologist Bruce Bean and neuroscientist and Nobel Prize winner Rod MacKinnon recommend that the method could also be a bit extra difficult. Their analysis hyperlinks muscle cramping to hyperactive nerves that ship messages from the mind and backbone to the skeletal muscle cells. It is assumed that fatigue, dehydration and low muscle glycogen can put this course of into movement.

“Regardless of the specific factors that trigger cramping, the end result is that some motor nerves become hyperactive, and the muscle cells connected to those nerves go into constant contraction until the hyperactivity is interrupted,” explains Bob Murray, who holds a Ph.D. in exercise physiology and is the managing principal at Sports Science Insights, LLC.

So how may you interrupt this course of to stop cramping? That’s what impressed Bean and MacKinnon to invent HOTSHOT, a 1.7-fluid-ounce sports activities shot. With the information that sure spices activate ion channels embedded within the nerves of the mouth, they reasoned that they could have the ability to inhibit the hyperactivation of the motor nerves by way of a sharp-tasting drink, thereby stopping cramping.

So far outcomes from research finished at Penn State University have proven promise in demonstrating how an athlete’s muscle mass and nerves work collectively to have an effect on efficiency—and the position a drink like HOTSHOT may play in decreasing cramps—however there’s nonetheless loads of ongoing analysis.

“The science is really interesting,” Antonucci says. “You still need to hydrate and take in salt, but this gets at the other side of the possible cause of cramps—the nerves.”

  1. Health and efficiency are linked to the state of our microbiome.

New analysis is revealing that microbes within the digestive system can have an effect on issues like weight, immune perform and—you guessed it—endurance efficiency. The microbiome is the bacterial group that lives on and inside us that has main implications for human health, and researchers have develop into notably all in favour of how the microbes in our guts may affect athletic efficiency.

The most fascinating findings as of late come from Jonathan Scheiman, a researcher at Harvard Medical School, who gathered fecal samples from runners who competed within the Boston Marathon. At a gathering of the American Chemical Society final summer time, he reported to have recognized a kind of micro organism in giant numbers in runners quickly after they completed a marathon. The thought is that strenuous exercise causes this micro organism to construct up within the bloodstream after which works to interrupt down lactic acid, which is related to fatigue and soreness.

The results of this rising science? Scheiman based Fitbiomics, a startup that’s working to create a probiotic that reduces fatigue and improves endurance efficiency.

Board-certified sports activities dietitian Bob Seebohar says that whereas there’s nonetheless a lot we don’t but perceive, that is one thing we must be taking note of, saying, “I believe all athletes should be focusing on improving their gut health, whether it be through taking probiotic supplements or consuming gut-friendly bacteria through foods like kefir, kombucha and other fermented foods.”

  1. What’s proper for one athlete’s intestine isn’t for an additional.

Another wing of the physique of analysis wanting into the microbes in our digestive methods is pointing to the truth that as a result of each intestine microbiome is totally different, we should always tailor our nutrition accordingly. One venture, dubbed the “American Gut Project” out of the University of California San Diego, is gathering samples from most of the people and thus far has found that there’s nice variety with regards to our microbial content material.

Following go well with, various personalised nutrition corporations are getting into the market, serving to to base shoppers’ dietary consumption on their particular person intestine micro organism. One of these is DayTwo, an Israeli firm co-founded by marathon runner Eran Segal, which just lately introduced a collaboration with the Mayo Clinic. By analyzing an individual’s microbiome, they work to foretell blood-sugar responses to totally different meals to enhance health and efficiency.

So may this enhance operating efficiency? Antonucci means that whereas promising, “we still need to know what specifically athletes need in their gut before we know what to put in there. We are making great strides in understanding the gut health for endurance athletes, but there’s more work to be done.”

  1. Hydrogel know-how permits for simpler absorption of carbohydrates.

We know that carbohydrates are important for endurance efficiency, however many runners expertise GI misery when making an attempt to absorb the beneficial quantities of sugar on the run. This is the place the thought to encapsulate or compact excessive concentrations of carbohydrates in a hydrogel was born. The ensuing firm, Maurten, is producing a brand new sort of sports activities drink and dealing with nutritionists, docs and researchers all over the world to review its efficacy.

While hydrogels are nothing new within the food business (they’re regularly used as thickeners and structurants), using them on this method is considerably groundbreaking. The neutral-tasting liquid drink transforms from liquid to gel type when it interacts with acid within the abdomen.

“If you take a really close look at the gel on a nano level, it consists of a structure that looks like a kitchen sponge,” explains Herman Reuterswärd, head of communication at Maurten. “In the pores of this structure, the carbohydrates are trapped or encapsulated.”

From there, the hydrogel permits for the graceful transport of the drink from the abdomen to the intestines, the place it may be successfully absorbed. This signifies that an athlete can tolerate larger quantities of the essential carbohydrates that gasoline endurance efficiency with out the excessive danger of GI misery.

Most notably, the science behind Maurten has additionally gotten buy-in from Yannis Pitsiladis on the University of Brighton who ran the Sub2 challenge. It’s additionally how Kenenisa Bekele began utilizing the drink in training and through one of many quickest marathons in historical past (the 2016 Berlin Marathon) which bodes nicely for the way forward for this new know-how.

  1. Ketones might supply a brand new sort of endurance gasoline.

We have lengthy recognized that a low-carb, high-fat (LCHF) eating regimen causes the physique to supply ketones within the liver, which may then be used as power. Unfortunately, for a lot of there are vital downsides to using this kind of food plan. This led scientists and athletes to marvel if it could be attainable to take a ketone complement to reap the advantages of this extra environment friendly supply of power with out truly having to comply with a LCHF weight-reduction plan. As such, researchers at Oxford gave cyclists a proprietary ketone drink referred to as HVMN (pronounced “human”) and located that their efficiency did certainly enhance, driving a mean of 400 meters farther throughout a half-hour time trial.

“Ketones are a more efficient source of energy for the body than glucose or fat. Glucose use for energy during elite performance is limited by the amount that can be taken up from the gut,” explains Kieran Clarke, a professor of physiological biochemistry at Oxford who led the research. “The cyclists who rode 400m farther had both ketones and glucose, in effect an extra fuel, rather like a car being able to run on diesel, petrol and electricity at the same time.”

In addition to offering an alternate power supply, Clarke says that the ketone drink decreases the speed of glycogen depletion, so an endurance athlete staves off that time of “hitting the wall.”

Other current analysis carried out on the Australian Institute of Sport truly discovered that ketone supplementation impaired endurance efficiency and induced abdomen upset. The research was short-term, and the riders’ stomachs might have acclimated to the drink over time, so the jury continues to be out.

  1. Clean ingredient lists take over.

A rising physique of analysis that questions the security of quite a few food components and fillers has had a profound affect on endurance nutrition in recent times. As a end result, a brand new class of merchandise has come to market with fewer fillers and extra sugars which are thought to probably trigger hassle for athletes.

“During exercise, the gut is under the stress of heat and hypoxia (low oxygen) due to the fact that blood is being diverted to the working tissues and heat is being produced from exercise,” explains senior analysis fellow at University of Waikato, Stacy Sims, Ph.D., additionally the co-founder of Osmo Nutrition who helped formulate Nuun’s new pure Performance drink. “When you ingest fillers and flow agents, even in small amounts, it increases the stress on the gut and kidneys, which can lead to GI distress, inflammation and a perturbation of the gut microbiome.”

While the definition of “clean” components and merchandise varies relying on whom you ask, for Nuun’s Performance line, Sims relied on vegan and non-GMO sugar sources, which means they haven’t been oxidized via the charred stays of animal bones, however fairly, by way of wooden charcoal. Other merchandise, like Gatorade Endurance, have had synthetic coloring faraway from their formulation.

“My suggestion is to look for products that contain minimal ingredients, only what is best utilized during a workout or race—electrolytes and sugars/carbohydrates,” provides Marni Sumbal, a board-certified sports activities dietitian and 12-time Ironman athlete.

  1. Carbohydrate-fasted exercises achieve growing help.

While the significance of periodizing training—altering quantity and depth to spice up fitness—is properly understood, an analogous strategy to nutrition is turning into extensively accepted because of a rising variety of research that help the follow. Most notably, that is completed via carbohydrate-fasted exercises, which contain withholding carbohydrates previous to particular exercises.

“What the research has shown is that training in a glycogen-depleted state stimulates mitochondrial biogenesis, which increases aerobic capacity and thereby enhances endurance performance,” explains Matt Fitzgerald, a licensed sports activities nutritionist and writer of TheEndurance Diet. “That’s why even short, high-intensity carb-fasted workouts are beneficial and why performance is improved even in relatively short time trials where fat-burning capacity is not a limiter.”

Indeed, the analysis has demonstrated the efficacy of this technique for cyclists, triathletes and runners alike. Even nonetheless, to be able to keep away from dips in efficiency, Sumbal suggests, “if you’re considering fasted workouts, consult with a board-certified sports dietitian for help.”
