Subjects were instructed annd to use any supplements or ergogenic substance mjscle the delaay protocol. Breakfast skipping and macronutrient intake with pre-existing illnesses that would impair training or those without a medical approval form were also excluded.
All experimental procedures were approved by the University Ethical Committee under protocol number CAAE: Informed consent was obtained from all individual participants included in the study. β-Alanine and a placebo resistant starch were supplied for 23 days using a double-blinded method Bex et al.
All subjects were instructed not to change their habitual diet during the intervention and to ensure that the participants took the supplements, as advised the participants received capsules with β-alanine or a placebo each week during the intervention.
All tests were conducted during the weekend on the same day and at the same hour. The km running test was performed at baseline and after 23 days. Subjects performed a 5 min warm up and 5-min stretch and were informed about the running course and procedures. Time in the km running test was measured and registered by a member of the research team who was waiting for the subjects at the end of the course.
Subjects were instructed to wear the same kind of clothing light shorts, light t-shirt, and running shoes in every test. Tests were executed at the same time of the day, temperature, and humidity conditions, according to the CGE official local weather forecast information.
Blood lactate concentration was measured through the collection of a drop of blood from the fingertip on a reagent strip using a Roche portable lactate analyzer.
The analyses were collected immediately after the km running tests. All groups received a standard training program with duration of 23 days, three running sessions per week on non-consecutive days. On the first day of each week, subjects were instructed to run a moderate volume 7 km. On the second day of training, the participants performed six sprints of m at maximum speed with a 2 min recovery interval between sprints.
On the third of training, the volunteers ran a long distance 12 km. To ensure that the running training protocol was appropriate, all routine were supervised by researchers. When the participants ran a long distance, trained monitors were positioned each m across distance to better control.
A 2 × 2 group × moment repeated measures analysis of variance RMANOVA with the Bonferroni adjustment for multiple comparisons was used to compare lactate concentration and performance. The partial eta-squared η 2 was calculated for moment. The data were analyzed using Statistic software version Table 1 presents the mean and SD values for age, body weight, and height at baseline in the placebo and beta-alanine groups.
There were no statistically significant differences between groups at baseline for any variable investigated. Figure 2 shows the differences in performance and delta for time between the placebo and β-alanine groups.

Figure 3 presents the differences in the lactate concentration between the placebo and β-alanine groups. FIGURE 3. Comparison between placebo and beta-alanine group according to lactate concentration after 10 km running.
To our knowledge, this was the first study to investigate the effects of β-alanine supplementation on a km running time trial in physically active adults. The main finding of this study was that β-alanine supplementation improved performance in km after 23 days of supplementation, with lower lactate concentration.
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. 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. The results of this study may be applied by coaches and trainers looking to improve performance in amateur runners.

Received: 05 February ; Accepted: 23 July ; Published: 08 August Ingested carnosine breaks down in the body into beta-alanine and histidine on absorption from the gut and only micro amounts of beta-alanine are found in the bloodstream. Research has shown that enough histidine is naturally present in the body to meet the demands of muscles for the synthesis of carnosine , and that the limiting factor is 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. CarnoSyn ® beta-alanine is the highest quality beta-alanine with 16 global patents.

Because it increases carnosine levels, beta-alanine supplementation may help improve athletic performance by decreasing fatigue and boosting endurance and performance during high intensity exercise. Animal studies show that further research into beta-alanine could help :. Learn about other supplements and vitamins for athletes here. Beta-alanine is a commonly available supplement in many sports-related products. However, it is also present in many protein sources, such as meat, fish, and poultry, albeit in lower quantities. To receive a sufficient amount to boost athletic performance, a person will likely require supplementation. Most of the food sources that contain beta-alanine are animal products. This means people following a vegan or vegetarian diet will likely have significantly less beta-alanine and carnosine in their system and require supplementation to enhance athletic performance. Learn more about supplements suitable for those following plant-based diets here. A study notes that more research is necessary to identify the most appropriate dosing strategy for beta-alanine supplementation. Some research suggests that 1. Similarly, other sources suggest that a person may consider a loading phase of 3. Advice includes dividing beta-alanine into 3 or 4 even doses a day and consuming them with main meals to help enhance uptake and manage potential side effects better. There are potential side effects associated with beta-alanine, especially if a person takes it in large doses, although they are not severe. These may include skin rashes and paresthesia , a tingling sensation on the skin. Learn about the side effects of drugs and supplements here. People often combine beta-alanine with other supplements, especially creatine and sodium bicarbonate. Creatine can improve performance in high intensity exercise by increasing the availability of adenosine triphosphate ATP , a molecule that every cell in the body produces. Research has found that combining beta-alanine and creatine can increase athletic performance. As such, many sports supplements may include both ingredients. Research suggests that using sodium bicarbonate and beta-alanine together may add additional improvement to this buffering capacity. Learn more about vitamins, minerals, and supplements in our dedicated hub. Beta-alanine is an amino acid that is a common ingredient in many sports supplement products. Some evidence suggests that it may help improve athletic performance and benefit overall health. Supplementing beta-alanine can help increase the concentration of carnosine in muscles, which regulates acids that accumulate from exercise, helping an individual avoid fatigue. Research notes that the supplement is safe and effective in appropriate doses and is unlikely to cause any serious adverse effects. While beta-alanine is present in protein sources such as meat, a person is unlikely to consume a sufficient amount from their diet to notice any benefit. A person can also combine it with other supplements, such as creatine and sodium bicarbonate, to try and further enhance performance.

The purpose of this study was Fatugue investigate the edlay of mkscle supplementation Thermogenic weight loss solutions a 10 km running time trial and lactate concentration in physically active adults. Ddlay to complete a km Beta-alanine and muscle fatigue delay time trial and Beta-alanine and muscle fatigue delay concentration following the test were Fat loss mindset transformation at baseline and post 23 days. Dellay running training program was performed three times per week on non-consecutive days day 1: running 7 km; day 2: six sprints of m at maximum speed with 2 min of recovery; day 3: running 12 km. When analyzing the delta Time post minus Time at baseline value there was a statistically significant difference between the β-alanine vs placebo group In conclusion, β-alanine supplementation improved the km running time trial and reduced lactate concentration in physically active adults. Beta-alanine β-alanine is a non-proteinogenic amino acid that combined with histidine can result in a dipeptide called carnosine, formed through an ATP-dependent reaction inside skeletal muscle mass Tiedje et al.
