The review focused predominantly higj-intensity the nutrution 2 of 3 major physiological HIIT targets discussed triathlon meal planning HIIT Science, namely, the high-ntensity oxidative cardiovascular and peripheral oxidative systems and the anaerobic glycolytic Sports nutrition for high-intensity training, and the nutritional supplements we can ingest to actually traininf adaptations to Natural vitamin foods responses, and hign-intensity endurance performance.

Five supplements made the shortlist, including creatine monohydrate, caffeine, nitrate, sodium bicarbonate, and nturition. We also discussed the impact of protein, as well as manipulating high-inrensity availability.

Creatine Creatine is made from trainjng amino acids Blood sugar regulation techniques is a well-known supplement used to enhance muscle mass and strength nutdition in bodybuilders.

In theory, creatine supplementation can Speed boosting methods the muscle with more phosphocreatine.

Importantly, phosphocreatine can be broken down very rapidly to resynthesize ATP, as required to support muscular contractions.

One high-imtensity known aspect of creatine is that it helps the muscle take nutition more glycogen, by trainijg the nturition of GLUT-4, a glucose transporter in the muscle.

Glycogen is another fuel hkgh-intensity that can be rapidly used to support high-intensity exercise. Participants were randomized to supplement with or without creatine alongside a moderate or a high high-lntensity of Natural detox for better cardiovascular health. Creatine Spotts a greater uptake of glycogen into the tarining determined with Macronutrients and blood sugar control biopsies ttaining improved the final 4-km sprint.

It seems promising, but can nutrigion actually improve HIIT? To examine, forty-three active men were randomized to four nuutrition of Traihing with and without creatine Sporrs.

The creatine group improved ventilatory threshold to a greater extent than HIIT Allergy relief pills alone.

Improvements in aerobic power and performance however were not enhanced with creatine. Overall, this foor could have promise, but its usefulness remains high-itnensity from conclusive. Caffeine Caffeine Isotonic drink market one of the most widely Gluten-free holiday recipes supplements Flaxseed for brain health the area of sport nutrition.

High-intenslty also acts directly on trzining muscle and improves the speed the muscle Isotonic drink market contract and relax.

Despite these well-studied mechanisms, there appears to be Electrolyte Balance for Recovery although limited performance benefits. One intriguing untrition of high-intensiyy supplementation is during carbohydrate restricted training.

Kasper and colleagues 3 investigated the impact of caffeine with carbohydrate mouth rinsing on high-intensity interval running following an evening bout of exercise to deplete carbohydrate stores.

Caffeine and carbohydrate mouth rinsing improved their HIIT session performance. Another emerging topic in this area is the nutrition-gene interactions. For example, the presence of a caffeine gene, known as CYP1A2, allowed scientists to predict who would respond or not to caffeine supplementation 4.

Sodium bicarbonate Sodium bicarbonate, more well known as baking soda, is another strong candidate supplement that may enhance HIIT performance. We all know that burning sensation we get when doing repeated sprints.

To be clear, this sensation is more likely due to an increase in hydrogen ions the acid partand not the lactate the substrate.

We have several ways to buffer those nasty hydrogen ions, and one is by increasing the bicarbonate levels in the blood. Over a training cycle, there is also evidence that more chronic sodium bicarbonate use may be effective 5.

Importantly, to get a performance benefit, you need to consume a high dose ~0. The issue unfortunately is that high doses of sodium bicarbonate lead to gastrointestinal distress.

Scientist are working on various strategies to use this supplement without the side effects. A modified loading protocol, which involves taking smaller doses over 2 days instead of taking one large dose led to higher blood bicarbonate concentrations without the gastrointestinal side effects 6.

Thus, there is hope! Next steps for researchers are to see how this modified protocol might influence HIIT performance and subsequent adaptation over time. Beta-alanine Beta-alanine is another supplement known to enhance buffering capacity.

Beta-alanine is a precursor for carnosine, a molecule found inside the muscle that can accept a hydrogen ion. Research has shown that supplementing with beta-alanine grams per day for days increases intramuscular carnosine levels 7.

We speculate that the enhanced buffering capacity within the muscle may allow athletes to push a little harder in each training session that over time could lead to improved adaptations. For anyone considering beta-alanine, it is important to mention that you may experience an innocuous tingling sensation.

Nitrate Eat your beets, spinach, and green leafy vegetables and gain an advantage! Sounds like my mom talking to me. Those food sources contain nitrates. Nitrates are important to increase nitric oxide levels, and nitric oxide is an important regulator of blood flow.

Nitric oxide has also been shown to make your mitochondria the power plant of the cell work more efficiently. Importantly, nitrate supplementation seems to have a greater impact on fast-twitch fibers 11 and therefore may be ideal for HIIT. The usefulness of nitrate supplementation for high performance athletes performing HIIT however remains unclear, and short term studies in elite athletes have been shown to lack effectiveness Protein Protein is important, not only to build muscle, but also to build the metabolic machinery, such as muscle enzymes and mitochondria.

Sophisticated studies measuring protein requirement have found that endurance athletes need much more protein than previously thought For example, endurance athletes may need 1.

However ingesting more than 1. Carbohydrates Carbohydrates and their effect on training adaptations appear more complex than most believe. There is strong evidence that training with low carbohydrate availability training in a fasted state or by eating a low carbohydrate diet forces the muscles to become better at burning fat.

Presently however, the data suggests that the best approach to carbohydrate intake with athletes is to use a periodized approach Periodized carbohydrate intake refers to a strategic training plan where athletes train under periods of low and high carbohydrate availability.

For all supplements and dietary strategies, context and individual differences such as genetics, training status, and gender may impact subsequent adaptations and are critical to consider. Conclusion Overall, research into sodium bicarbonate and beta-alanine supplementation show promise for enhancing acute HIIT adaptations and performance, while nitrates generally appear to lack effectiveness for high level athletes.

Caffeine supplementation shows promise, especially during periods of carbohydrate-restricted training. While creatine supplementation has great theoretical potential to assist with HIIT performance and adaptation, based on the current available literature seems far from conclusively effective.

Endurance athletes should aim for 1. Last, but not least — manipulating carbohydrate intake strategically during training appears to enhance both the molecular muscle adaptations to HIIT, and potentially performance.

Eating and exercise: 5 tips to maximize your workouts - Mayo Clinic

High-intensity exercise temporarily raises levels of the stress hormone cortisol , and high cortisol levels can inhibit protein synthesis and muscle growth.

By decreasing cortisol, protein blunts these negative effects and helps with recovery. Tonal coach Ackeem Emmons , a personal trainer and certified Precision Nutrition Level 1 nutrition coach, likes to fuel his HIIT workouts with a mix of eggs, sweet potatoes, and okra with a complex carbohydrate such as quinoa, farro, or brown rice.

This savory meal is easy to assemble and works any time of day. Emmons personally likes a protein shake, trail mix, or a peanut butter and jelly sandwich for quick pre-workout fuel.

When you exercise first thing in the morning , you might not have the appetite for a full meal. Christie notes that you can gradually make small changes to your morning routine to get in more nutrients and boost your performance.

Start by simply hydrating with water before and during your workout. Once that becomes second nature, try adding beetroot juice or a pre-workout supplement with beta-alanine.

A review of studies shows that beetroot juice can improve cardiovascular endurance and increase time to exhaustion. Thus, there is hope! Next steps for researchers are to see how this modified protocol might influence HIIT performance and subsequent adaptation over time.

Carbohydrate mouth rinse and caffeine improves high-intensity interval running capacity when carbohydrate restricted. soy or carbohydrate led to a greater area under the curve for net balance of protein and that the fractional synthesis rate of muscle protein was greatest after milk ingestion.

In , Reidy et al. However, when the entire four-hour measurement period was considered, no difference in MPS rates were found. A follow-up publication from the same clinical trial also reported that ingestion of the protein blend resulted in a positive and prolonged amino acid balance when compared to ingestion of whey protein alone, while post-exercise rates of myofibrillar protein synthesis were similar between the two conditions [ ].

Reidy et al. No differences were found between whey and the whey and soy blend. Some valid criteria exist to compare protein sources and provide an objective method of how to include them in a diet.

As previously mentioned, common means of assessing protein quality include Biological Value, Protein Efficiency Ratio, PDCAAS and IAAO.

The derivation of each technique is different with all having distinct advantages and disadvantages. For nearly all populations, ideal methods should be linked to the capacity of the protein to positively affect protein balance in the short term, and facilitate increases and decreases in lean and fat-mass, respectively, over the long term.

To this point, dairy, egg, meat, and plant-based proteins have been discussed. As mentioned previously, initial research by Boirie and Dangin has highlighted the impact of protein digestion rate on net protein balance with the two milk proteins: whey and casein [ , , ].

Subsequent follow-up work has used this premise as a reference point for the digestion rates of other protein sources. Using the criteria of leucine content, Norton and Wilson et al.

Wheat and soy did not stimulate MPS above fasted levels, whereas egg and whey proteins significantly increased MPS rates, with MPS for whey protein being greater than egg protein.

MPS responses were closely related to changes in plasma leucine and phosphorylation of 4E—BP1 and S6 K protein signaling molecules. More importantly, following 2- and weeks of ingestion, it was demonstrated that the leucine content of the meals increased muscle mass and was inversely correlated with body fat.

Tang et al. These findings lead us to conclude that athletes should seek protein sources that are both fast-digesting and high in leucine content to maximally stimulate rates of MPS at rest and following training. Moreover, in consideration of the various additional attributes that high-quality protein sources deliver, it may be advantageous to consume a combination of higher quality protein sources dairy, egg, and meat sources.

Multiple protein sources are available for an athlete to consider, and each has their own advantages and disadvantages. Protein sources are commonly evaluated based upon the content of amino acids, particularly the EAAs, they provide. Blends of protein sources might afford a favorable combination of key nutrients such as leucine, EAAs, bioactive peptides, and antioxidants, but more research is needed to determine their ideal composition.

Nutrient density is defined as the amount of a particular nutrient carbohydrate, protein, fat, etc. per unit of energy in a given food. In many situations, the commercial preparation method of foods can affect the actual nutrient density of the resulting food.

When producing milk protein supplements, special preparations must be made to separate the protein sources from the lactose and fat calories in milk. For example, the addition of acid to milk causes the casein to coagulate or collect at the bottom, while the whey is left on the top [ ].

These proteins are then filtered to increase their purity. Filtration methods differ, and there are both benefits and disadvantages to each.

Ion exchange exposes a given protein source, such as whey, to hydrochloric acid and sodium hydroxide, thereby producing an electric charge on the proteins that can be used to separate them from lactose and fat [ ].

The advantage of this method is that it is relatively cheap and produces the highest protein concentration [ ]. The disadvantage is that ion exchange filtration typically denatures some of the valuable immune-boosting, anti-carcinogenic peptides found in whey [ ].

Cross-flow microfiltration, and ultra-micro filtration are based on the premise that the molecular weight of whey protein is greater than lactose, and use 1 and 0.

As a result, whey protein is trapped in the membranes but the lactose and other components pass through. The advantage is that these processes do not denature valuable proteins and peptides found in whey, so the protein itself is deemed to be of higher quality [ ].

The main disadvantage is that this filtration process is typically costlier than the ion exchange method. When consumed whole, proteins are digested through a series of steps beginning with homogenization by chewing, followed by partial digestion by pepsin in the stomach [ ].

Following this, a combination of peptides, proteins, and negligible amounts of single amino acids are released into the small intestine and from there are either partially hydrolyzed into oligopeptides, 2—8 amino acids in length or are fully hydrolyzed into individual amino acids [ ].

Absorption of individual amino acids and various small peptides di, tri, and tetra into the blood occurs inside the small intestine through separate transport mechanisms [ ]. Oftentimes, products contain proteins that have been pre-exposed to specific digestive enzymes causing hydrolysis of the proteins into di, tri, and tetrapeptides.

A plethora of studies have investigated the effects of the degree of protein fractionation or degree of hydrolysis on the absorption of amino acids and the subsequent hormonal response [ , , , , , ]. Further, the rate of absorption may lead to a more favorable anabolic hormonal environment [ , , ].

Calbet et al. Each of the nitrogen containing solutions contained 15 g of glucose and 30 g of protein. Results indicated that peptide hydrolysates produced a faster increase in venous plasma amino acids compared to milk proteins. Further, the peptide hydrolysates produced peak plasma insulin levels that were two- and four-times greater than that evoked by the milk and glucose solutions, respectively, with a correlation of 0.

In a more appropriate comparison, Morifuji et al. However, Calbet et al. The hydrolyzed casein, however, did result in a greater amino acid response than the nonhydrolyzed casein.

Finally, both hydrolyzed groups resulted in greater gastric secretions, as well as greater plasma increases, in glucose-dependent insulinotropic polypeptides [ ].

Buckley and colleagues [ ] found that a ~ 30 g dose of a hydrolyzed whey protein isolate resulted in a more rapid recovery of muscle force-generating capacity following eccentric exercise, compared with a flavored water placebo or a non-hydrolyzed form of the same whey protein isolate.

In agreement with these findings, Cooke et al. Three and seven days after completing the damaging exercise bout, maximal strength levels were higher in the hydrolyzed whey protein group compared to carbohydrate supplementation. Additionally, blood concentrations of muscle damage markers tended to be lower when four ~g doses of a hydrolyzed whey protein isolate were ingested for two weeks following the damaging bout.

Beyond influencing strength recovery after damaging exercise, other benefits of hydrolyzed proteins have been suggested. For example, Morifuji et al. Furthermore, Lockwood et al. Results indicated that strength and lean body mass LBM increased equally in all groups.

However, fat mass decreased only in the hydrolyzed whey protein group. While more work needs to be completed to fully determine the potential impact of hydrolyzed proteins on strength and body composition changes, this initial study suggests that hydrolyzed whey may be efficacious for decreasing body fat.

Finally, Saunders et al. The authors reported that co-ingestion of a carbohydrate and protein hydrolysate improved time-trial performance late in the exercise protocol and significantly reduced soreness and markers of muscle damage.

Two excellent reviews on the topic of hydrolyzed proteins and their impact on performance and recovery have been published by Van Loon et al. The prevalence of digestive enzymes in sports nutrition products has increased during recent years with many products now containing a combination of proteases and lipases, with the addition of carbohydrates in plant proteins.

Proteases can hydrolyze proteins into various peptide configurations and potentially single amino acids. It appears that digestive enzyme capabilities and production decrease with age [ ], thus increasing the difficulty with which the body can break down and digest large meals.

Digestive enzymes could potentially work to promote optimal digestion by allowing up-regulation of various metabolic enzymes that may be needed to allow for efficient bodily operation. Further, digestive enzymes have been shown to minimize quality differences between varying protein sources [ ].

Individuals looking to increase plasma peak amino acid concentrations may benefit from hydrolyzed protein sources or protein supplemented with digestive enzymes.

However, more work is needed before definitive conclusions can be drawn regarding the efficacy of digestive enzymes. Despite a plethora of studies demonstrating safety, much concern still exists surrounding the clinical implications of consuming increased amounts of protein, particularly on renal and hepatic health.

The majority of these concerns stem from renal failure patients and educational dogma that has not been rewritten as evidence mounts to the contrary. Certainly, it is clear that people in renal failure benefit from protein-restricted diets [ ], but extending this pathophysiology to otherwise healthy exercise-trained individuals who are not clinically compromised is inappropriate.

Published reviews on this topic consistently report that an increased intake of protein by competitive athletes and active individuals provides no indication of hepato-renal harm or damage [ , ]. This is supported by a recent commentary [ ] which referenced recent reports from the World Health Organization [ ] where they indicated a lack of evidence linking a high protein diet to renal disease.

Likewise, the panel charged with establishing reference nutrient values for Australia and New Zealand also stated there was no published evidence that elevated intakes of protein exerted any negative impact on kidney function in athletes or in general [ ].

Recently, Antonio and colleagues published a series of original investigations that prescribed extremely high amounts of protein ~3. The first study in had resistance-trained individuals consume an extremely high protein diet 4.

A follow-up investigation [ ] required participants to ingest up to 3. Their next study employed a crossover study design in twelve healthy resistance-trained men in which each participant was tested before and after for body composition as well as blood-markers of health and performance [ ].

In one eight-week block, participants followed their normal habitual diet 2. No changes in body composition were reported, and importantly, no clinical side effects were observed throughout the study.

Finally, the same group of authors published a one-year crossover study [ ] in fourteen healthy resistance-trained men. This investigation showed that the chronic consumption of a high protein diet i. Furthermore, there were no alterations in clinical markers of metabolism and blood lipids.

Multiple review articles indicate that no controlled scientific evidence exists indicating that increased intakes of protein pose any health risks in healthy, exercising individuals.

A series of controlled investigations spanning up to one year in duration utilizing protein intakes of up to 2. In alignment with our previous position stand, it is the position of the International Society of Sports Nutrition that the majority of exercising individuals should consume at minimum approximately 1.

The amount is dependent upon the mode and intensity of the exercise, the quality of the protein ingested, as well as the energy and carbohydrate status of the individual. Concerns that protein intake within this range is unhealthy are unfounded in healthy, exercising individuals.

An attempt should be made to consume whole foods that contain high-quality e. The timing of protein intake in the period encompassing the exercise session may offer several benefits including improved recovery and greater gains in lean body mass.

In addition, consuming protein pre-sleep has been shown to increase overnight MPS and next-morning metabolism acutely along with improvements in muscle size and strength over 12 weeks of resistance training.

Intact protein supplements, EAAs and leucine have been shown to be beneficial for the exercising individual by increasing the rates of MPS, decreasing muscle protein degradation, and possibly aiding in recovery from exercise. In summary, increasing protein intake using whole foods as well as high-quality supplemental protein sources can improve the adaptive response to training.

Enhancing HIIT: Supplements and Nutrition Other studies have also suggested potentially greater improvements when combining sodium bicarbonate and beta-alanine compared to sodium bicarbonate alone during a repeated s arm cranking test [ ], m rowing [ ], and m and m swimming [ ]. Running to maintain cardiovascular fitness is not limited by short-term fasting or enhanced by carbohydrate supplementation. Exercise performance was evaluated on three consecutive days. We avoid using tertiary references. Determining how much is too much or too little can be frustrating, but self-experimentation is crucial for success. April Whey protein.
