Purpose: Recent research has shown that chronic dietary beta-alanine (betaALA) supplementation increases muscle carnosine content, which is associated with better performance in short (1-2 min) maximal exercise. Success in endurance competitions often depends on a final sprint. However, whether betaALA can be ergogenic in sprint performance at the end of an endurance competition is at present unknown. Therefore, we investigated the effect of 8-wk betaALA administration in moderately to well-trained cyclists on sprint performance at the end of a simulated endurance cycling race.
Methods: A double-blind study was performed, which consisted of two experimental test sessions interspersed by an 8-wk betaALA (2-4 g.d; n = 9) or matched placebo (PL; n = 8) supplementation period. In the pretesting and the posttesting, subjects performed a 10-min time trial and a 30-s isokinetic sprint (100 rpm) after a 110-min simulated cycling race. Capillary blood samples were collected for determination of blood lactate concentration and pH.

Results: Mean power output during the time trial was approximately 300 W and was similar between PL and betaALA during either the pretesting or the posttesting. However, compared with PL, during the final sprint after the time trial, betaALA on average increased peak power output by 11.4% (95% confidence interval = +7.8 to +14.9%, P = 0.0001), whereas mean power output increased by 5.0% (95% confidence interval = +2.0 to +8.1%, P = 0.005). Blood lactate and pH values were similar between groups at any time.
Background: Intermittent bouts of high-intensity exercise result in diminished stores of energy substrates, followed by an accumulation of metabolites, promoting chronic physiological adaptations. In addition, beta-alanine has been accepted has an effective physiological hydrogen ion (H+) buffer. Concurrent high-intensity interval training (HIIT) and beta-alanine supplementation may result in greater adaptations than HIIT alone. The purpose of the current study was to evaluate the effects of combining beta-alanine supplementation with high-intensity interval training (HIIT) on endurance performance and aerobic metabolism in recreationally active college-aged men.
Methods: Forty-six men (Age: 22.2 +/- 2.7 yrs; Ht: 178.1 +/- 7.4 cm; Wt: 78.7 +/- 11.9; VO2peak: 3.3 +/- 0.59 l.min-1) were assessed for peak O2 utilization (VO2peak), time to fatigue (VO2TTE), ventilatory threshold (VT), and total work done at 110% of pre-training VO2peak (TWD). In a double-blind fashion, all subjects were randomly assigned into one either a placebo (PL - 16.5 g dextrose powder per packet; n = 18) or beta-alanine (BA - 1.5 g beta-alanine plus 15 g dextrose powder per packet; n = 18) group. All subjects supplemented four times per day (total of 6 g/day) for the first 21-days, followed by two times per day (3 g/day) for the subsequent 21 days, and engaged in a total of six weeks of HIIT training consisting of 5-6 bouts of a 2:1 minute cycling work to rest ratio.
Conclusion: The use of HIIT to induce significant aerobic improvements is effective and efficient. Chronic BA supplementation may further enhance HIIT, improving endurance performance and lean body mass.
2017 300rr. I broke the stock computer and need to get something that tracks speed and trip mileage. I am thinking about a trailtech endurance II because it is the cheapest one I can find that has the functions I need.
Does anyone have experience with it? Does it use the stock plug and pickup? Would I be better off replacing with a stock unit?
It also takes a reed switch style input for wheel speed sensor - it doesn't need that wheel sensor to be powered like the Beta computer is so you can just snip the beta wheel speed connector off at the bar side and solder the 2 wire connector the trailtech computer will use.
If I had to do it over again I woulda bought the KTM endurance 2 kit cause it would come with (I believe) a wheel speed sensor thats threaded like the betas use. All in (endurance 2 kit and mount kit with protector) its about the same price as the shitty beta oem computer and doesn't have the useless idiot lights once you've removed the oil injection system.
Despite this, beta-alanine supplementation will still increase carnosine concentrations, regardless of low or high baseline levels [19, 20], with no upper limit for muscle carnosine concentrations having yet been identified. While cross-sectional studies have shown higher baseline carnosine contents in the gastrocnemius muscle of sprinters [7] and resistance-trained athletes [6] versus their untrained counterparts, beta-alanine supplementation has also been shown to increase muscle carnosine in both trained [20] and untrained [1] populations. A recent study by Bex et al. [21] suggests that increases in whole muscle carnosine concentrations may be slightly higher in trained athletes compared to non-athletes supplementing with beta-alanine, but more research is needed to replicate this finding and account for potential differences in single muscle fiber concentrations. Much of the research evaluating increases in muscle carnosine has been performed in young males, but evidence also suggests that beta-alanine supplementation is effective in females [22, 23] and the elderly [24].
Where PrePLis the pre-test value in the placebo group, PostPL is the post-test value in the placebo group, PreBA is the pre-test value in the beta-alanine group, and PostBA is the post-test value in the beta-alanine group.
Collectively, the body of literature suggests a modest additive effect when adding SB to beta-alanine supplementation in exercise bouts in which metabolic acidosis may be performance-limiting. While this additive benefit is not typically revealed with traditional statistical analyses, studies using magnitude-based inferences have suggested that a modest additive effect is likely to exist [62, 65, 68]. The studies reviewed have used supplement dosages ranging from 4.8-6.8 g/kg/day of beta-alanine for at least 28 days, and 0.3-0.5 g/kg of SB taken acutely. However, the only study to indicate a statistically significant synergistic effect of beta-alanine and SB [82] employed a unique dosing protocol for SB, providing daily doses of 0.5 g/kg/day for seven days, whereas other studies typically provide a dose of 0.3 g/kg acutely in the hours preceding the exercise bout. Individual responses to SB supplementation may vary, likely due to side effects including headache and gastrointestinal discomfort [68, 85, 87]. In terms of practical application, those wishing to combine beta-alanine and SB supplementation must carefully evaluate the dosage and timing with which SB is consumed and weigh the modest additive benefit against the risk of potentially ergolytic side effects.
The idea with beta alanine is that it stores carnosine in muscles, which buffers against acid. It seems that it DOES increase carnosine, but doesn't increase buffering that much. There's also some concern that the body will ease off its own natural buffering because of the artificial buffering. No proof of that though.
The known supplemental dietary buffers are sodium bicarbonate, which works well for sprinters but needs such a high dose that it causes severe gastrointenstinal issues, and beta-alanine, which has some research to support it as well (at least one showing improved running economy) but is still a "young" supplement.

Re-energizes ATP production to extend exercise performance. Supports efficient disposal and repair of tissues damaged by exercise, increases muscle satellite cell count, and triples muscle glycogen accumulation rate after depletion due to intense endurance training.
A: Beta-Alanine is an amino acid that interacts directly with the amino acid carnosine to buffer lactic acid. With intense training, you can increase your carnosine levels with a limiting factor: the body cannot produce enough Beta-Alanine to allow the body to continue to increase carnosine levels. Clinical studies show that supplementing with Beta-Alanine allows the body to produce significantly higher carnosine levels. The result is a highly effective mechanism for the metabolism of lactate, which in-turn improves endurance capacity.
However, the research is lacking in observing the effects of it for efforts longer than thirty minutes. The end goal of supplementation is to increase muscular concentrations of carnosine and reduce muscle pH. That means the reported benefits are mostly limited to the short working duration of the anaerobic energy system. Overall, the results suggest that beta-alanine may improve the effects of high-intensity interval training and reduce neuromuscular fatigue, which would be welcome by most cyclists.
Beta-alanine is a reasonably well-researched supplement. The research in endurance sports is somewhat limited, cycling in particular. Listed below are several studies that you can read through for more information.
However, a review of studies of the beta-alanine supplement shows that it doesn't increase muscle strength or aerobic endurance. Instead, it appears to slightly increase the amount of time an athlete can perform high-intensity exercises, such as weight lifting and sprinting, before getting exhausted.
It's not clear exactly what benefits can be gained from taking beta-alanine supplements. Some research suggests that boosting the levels of carnosine in the muscles may take weeks of using supplements. 589ccfa754
