Whilst this finding is of interest, it remains unclear as to whether it would be sufficient to result in improved exercise performance, particularly in the absence of any changes to the force—frequency relationship, peak force production, or contraction time.

Introduction Carnosine β-alanyl- L -histidine is a cytoplasmic dipeptide, synthesised from β-alanine BA and histidine and is found in high concentrations in skeletal muscle.

Methods Ethical approval All participants were fully informed of any risks and discomforts associated with the study. Participants Twenty-four male participants were allocated to the two supplement groups [placebo PLA or BA] on the basis of maximal voluntary isometric force MVIF values recorded during familiarisation.

Study design This was a double-blind, placebo-controlled study with all raw data analyses, exclusions, and statistical analyses undertaken blind to the supplement group.

Supplementation Participants were provided with 6. Experimental setup The experimental setup for the determination of isometric knee extension force, EMG, and electrical stimulation in our laboratory has been described in detail previously Hannah et al.

Electromyography EMG signals were recorded from the superficial quadriceps: m. Electrical stimulation Knee extensor contractile properties were assessed using a constant current variable voltage stimulator DS7AH; Digitimer, Welwyn Garden City, UK.

Protocol and measurements Identification of force and EMG onset for all evoked and voluntary contractions was conducted manually using visual identification Hannah et al.

Resting twitches A single electrical impulse was delivered with stepwise increments in the current to evoke a twitch response, until a plateau in the amplitude of twitch force and compound muscle action potentials M-waves was reached. Octet contractions Octet contractions 8 impulses at Hz were evoked via supramaximal stimulation of the femoral nerve.

Force—frequency relationship Tetanic contractions were elicited via submaximal percutaneous electrical stimulation of the quadricep to examine the force—frequency relationship Lamont and Miller Blood samples Fingertip capillary blood samples were taken at rest, immediately prior to and 5 min following the sustained fatigue hold.

Although long-distance running relies mainly on aerobic energy metabolism, some studies have demonstrated that mean running speed in prolonged running is dependent on lactate concentration, showing an association between lower lactate accumulations and higher running speed and anaerobic threshold Sjodin and Jacobs, ; Fohrenbach et al.

Our findings showed that β-alanine supplementation decreased lactate concentration after a km running trial, suggesting that the improvement in performance was due in part to lower blood lactate accumulation. Previous studies have investigated the influence of β-alanine on lactate accumulation during exercise.

These findings corroborate with others Jordan et al. We hypothesize that the increase in km running performance after β-alanine supplementation observed in the present study may be in part due to the increased muscular buffering capacity, mainly through lower demand on anaerobic glycolysis, generating lower lactate accumulation.

Furthermore, long running duration induced physiological and neuromuscular alterations that impair running speed Davies and Thompson, ; Giandolini et al. Lower muscular excitability induced by prolonged running may be associated with the reduction in muscle glycogen and higher production of reactive oxygen species ROS Duhamel et al.

In addition, carnosine has also been reported to decrease ROS production, with an anti-oxidant activity Kohen et al. We hypothesize that the improvement in km running performance induced by β-alanine supplementation in this study could also be explained by the effect of carnosine on intramuscular calcium influx and anti-oxidant activity, delaying neuromuscular fatigue.

However, more studies are needed to better understand this mechanism. Despite the importance of this study, some limitations need to be mentioned, such a lack of intramuscular analysis, muscle carnosine concentration, and muscle buffering capacity.

Therefore, we suggest further research to analyze the effects of β-alanine supplementation on running time trials over different distances and investigate muscular adaptations in different populations, such as athletes.

In summary, β-alanine supplementation improved a km running time trial and decreased blood lactate concentrations in physically active adults. These results suggest that β-alanine supplementation has positive effects on prolonged running. The present study suggests that β-alanine supplementation can be used as a nutritional strategy to improve performance in km running by lowering blood lactate accumulation.

Beta-alanine and muscle fatigue delay -

Beta-Alanine Food Sources. Beta-alanine works by binding with histidine in both the brain and the muscles. This binding creates carnosine. By increasing carnosine levels, we can prevent the acid build-up that contributes to fatigue when training. Another study found that beta-alanine improved exercise capacity and power, mainly when performing short bursts of high-intensity exercise.

Quick Tip: Beta-alanine works by enhancing carnosine levels to delay muscle fatigue and speed recovery. How Beta-Alanine Works. Simply put, beta-alanine can fuel better performance, bigger gains, faster recovery, and laser focus.

Many athletes rely on beta-alanine to supplement their workouts and surpass their training goals. Learn more about the benefits of beta-alanine. Delaying the onset of fatigue gives athletes a competitive edge to break through and test their limits.

High-quality supplementation is proven to speed recovery time and enhance mental focus, which helps athletes move through tough training and workouts with greater ease. Athletes are constantly challenging their muscles to work harder under greater tension.

Beta-alanine can give that extra edge to push gains to the limit. Improving endurance allows for extended training at harder intervals, pushing out those game-changing extra reps for better gains.

Higher levels of muscle carnosine can speed up recovery. Beta-alanine increases muscle carnosine, preventing the acid build-up that contributes to soreness and fatigue. Quicker recovery means spending more time training. Read more about a day study involving 18 elite soldiers who found that beta-alanine supplementation improved cognitive function during combat testing sessions.

Quick Tip: Beta-alanine can fuel better performance and lead to bigger gains, faster recovery, and laser focus. Delving deeper into the science behind beta-alanine, we can explore a process called glycolysis, as well as what triggers fatigue and how carnosine buffers that decline.

Glycolysis is the breaking down of glucose in the body to generate energy. For sustained or intermittent high-intensity exercise, glucose is the primary energy source.

When we exercise, highly reactive hydrogen ions cause a fall in pH in our muscle, a process also referred to as acidification. Throughout our workout, hydrogen ions can be actively transported from the muscle cells and into our circulatory system.

However, at higher exercise intensities, the rate of hydrogen ion production becomes increasingly insufficient. Progressive acidification may then occur, especially in the strength-generating fast-twitch muscle fibers.

As the muscle pH falls, it exacerbates the onset of fatigue. This rise in acidity compromises the proteins responsible for power generation and shortening of the muscle fibers.

Basically, carnosine buffers that pH decline. When histidine attaches to beta-alanine, it takes on an additional hydrogen ion.

The histidine half of the carnosine molecule acts as a buffer, but the beta-alanine half is equally as important. It prevents the histidine from combining with other amino acids to form proteins. As a result, high concentrations of carnosine accumulate in the muscle cells.

Quick Tip: As acidity rises and pH in the muscle drops, fatigue can set in. Carnosine acts as a buffer during that decline. Studies have shown that beta-alanine can have a significant impact on body composition.

According to one study , athletes have achieved an increase in lean muscle mass in just three weeks. Greater endurance leads to an increase in stamina and strength, which accelerates muscle growth. Top performers supplement with beta-alanine because it works.

See documented results with before and after photos of professional athletes here. Quick Tip: Beta-alanine can boost athletic performance, which leads to an increase in lean muscle mass. Beta-alanine is a naturally occurring amino acid that supports the synthesis of muscle carnosine in the body.

Carnosine acts as a buffer against a drop in pH and delays the onset of muscle fatigue and failure. Beta-alanine is also found in foods such as meat and fish. It combines with the amino acid histidine to form the dipeptide called carnosine.

Carnosine is a dipeptide, or a compound made up of two linked amino acids: beta-alanine and histidine. More specifically, this compound is in the active tissues of the body, including the heart and the brain.

Carnosine is instrumental in the improvement of muscle strength and performance during exercise. During exercise or training sessions, through the process of glycolysis, glucose is broken down, and pyruvate is produced, which is sometimes converted to a chemical known as lactate. Lactate produces high quantities of hydrogen ions.

The increased acidity lowers the pH level in the muscles. The acidity in the tissues blocks the process of glycolysis reduces the elasticity of the muscles. That decrease in elasticity is the origin of exhaustion and fatigue during exercise.

The introduction of beta-alanine in the body, and in turn, higher levels of carnosine act as a buffer against a drop in pH and reduce acidity levels in the muscles during exercises. The reduction of fatigue tells us that beta-alanine is beneficial to professional athletes and those looking to gain a competitive edge.

Quick Tip: Beta-alanine and carnosine work together to reduce fatigue by lowering the levels of acidity in muscles. Orally ingested carnosine breaks down into beta-alanine and histidine on absorption from the gut. Only micro amounts of beta-alanine make their way to the bloodstream.

Research tells us that the body has enough histidine to meet the demands of muscles for synthesizing carnosine, but not enough beta-alanine. Beta-alanine supplementation augments the small amounts available from 1 synthesis in the liver, and 2 from the ingestion of meat and fish. Supplemental beta-alanine combines with the naturally occurring histidine to increase the levels of carnosine.

Quick Tip: The most effective way to increase carnosine levels in the body is to supplement with the right dosage of beta-alanine.

Supplementing with beta-alanine is not just for athletes. Beta-alanine is making an impact in the general wellness and healthy aging market. As a critical building block of carnosine, this powerful antioxidant can support healthy aging throughout the body.

Regardless of your athletic status, these are the top five reasons to take beta-alanine:. Carnosine is a powerful antioxidant. Its strong anti-glycation ability protects the brain and supports cognitive function and mental acuity.

It may also decrease occasional anxiety, support memory, delay mental fatigue, speed up executive function, and increase focus. Carnosine helps regulate muscle contractions and prevent lipid oxidation in the body. It also supports healthy circulation and already-healthy blood pressure levels through vasodilation.

Carnosine promotes muscle quality and function. Muscle function is vital in supporting our frame, aiding balance, and maintaining strength for everyday activity.

Carnosine chelates heavy metals, supports blood sugar levels already in the healthy range, regulates immune system response , and acts as an anti-inflammatory factor. Its antioxidant properties protect against free radicals throughout the body. Carnosine benefits bone and joint health through its anti-glycation action.

Carnosine can contribute to overall skeletal integrity by directly protecting bone structure and supporting muscle function. Quick Tip: Beta-alanine can make a significant impact on your overall wellness, including brain health, heart health, muscle function, systemic protection, and bone health.

Most individuals do not consume enough beta-alanine in their diets to increase athletic performance. Since meat, poultry, and fish are the highest dietary sources of beta-alanine, vegetarian athletes have an even greater need to supplement beta-alanine levels.

It is critical for those with vegan or vegetarian dietary restrictions to supplement with beta-alanine to ensure healthy carnosine levels. Quick Tip: Vegans and vegetarians need to supplement with beta-alanine because meat sources are the most common source of beta-alanine.

Learn More. The most important thing to remember about when to take beta-alanine is to dose every day—even on non-workout days. The concentration of muscle carnosine builds over time. How and when you get your daily dose is a matter of preference.

A meta-analysis conducted by Hobson et al. They found that β-alanine supplementation was most effective in high-intensity exercise with a duration between 1 and 4 min, showing no effect of β-alanine supplementation in exercises shorter than 60 s. Another meta-analysis found similar results, in which β-alanine supplementation had greater impact in exercises with a duration between 0.

Furthermore, the majority of investigations of β-alanine in the literature used a cycle ergometer, but few studies have analyzed the influence of β-alanine supplementation on running performance.

Smith et al. On the other hand, Ducker et al. In accordance with Ducker et al. The ergogenic effect of β-alanine supplementation is widely due to the increase in intramuscular carnosine content, which improves skeletal muscle buffering capacity Culbertson et al.
