LACTAT BUFFER by SPONSER® is a mildly flavoured beverage powder with sodium citrate and bicarbonate for high-intensity, so-called anaerobic-lactacid sports.
During high-intensity exercise, muscle hyperacidity and the consequent accumulation of lactate as well as a short-term drop in blood pH are often performance-limiting factors. The athlete becomes «acidic» and his performance is limited. LACTAT BUFFER provides for an improved «acid buffer capacity» and thus increased lactate tolerance. This means that the athlete, with his individual tolerance of the lactate developed through training adaptation, can longer endure a given load or achieve a higher performance in the same time.
Sodium bicarbonate is listed by internationally renowned institutions from sports and nutrition science (Swiss Sports Nutrition Society, Australian Institute of Sport) as a so-called A-supplement with the highest effectiveness.
Which sports benefit?
-Typical anaerobic lactacidal loads:
Swimming, athletics (short and medium distances), rowing, skiing, cross-country skiing (sprint)
-repetitive interval loads:
various team sports (football, hockey), power sports, martial arts (karate, judo)
Function and effect of soda loading
Supplementation with LAKTAT BUFFER or sodium bicarbonate and/or citrate is also called soda loading. Significant performance improvements can be expected when using sodium bicarbonate and sodium citrate for high-intensity anaerobic loads of approx. 1 to 10 minutes.
Performance improvements seem to be the more pronounced the stronger the stress induced metabolic hyperacidity (acidosis) is. In practice, the anaerobic stress is more beneficial for accustomed athletes such as middle-distance runners, rowers, swimmers, skiers, etc. than for endurance athletes such as long-distance runners, triathletes or cyclists. This is because in anaerobic sports athletes train lactate tolerance more often than in endurance sports.
Another group of athletes who can potentially benefit from soda loading are those with repetitive interval loads. This applies to many team sports, ball sports and martial arts.
Soda-loading is also interesting for strength athletes, as the isolated training of fewer muscles produces very high local lactate values, which must be removed as quickly as possible. If the muscle remains « sour » for too long, the next set cannot be completed quickly enough and with sufficient strain. Since soda loading also means an increased sodium intake, supplementation in weight training should not be carried out permanently but reserved for intensive phases. The same applies to sports where one or even several competitions take place every week.
Due to the mode of action of an increased bicarbonate buffer in the blood, the individual lactate value of the athlete is not necessarily increased, but primarily the lactate tolerance. This means that the athlete with his individual lactate value can endure a load for a longer time or achieve a higher performance. The athlete does not necessarily interpret the perceived load as lower if the maximum achievable performance in competition is aimed at. In contrast however, a given, defined performance should be perceived as less stressful. In all cases a much faster recovery is to be expected, because the acid removal is accelerated by the increased buffer capacity. This means faster disappearance of the "stiff" muscle feeling after exercise as well as faster recovery.
As early as 1993, a first meta-analysis examined 29 studies on athletes with soda loading. Overall, the performance until exhaustion was massively increased with an average of 27%. Due to the diversity of the study designs, however, also with a large variation of +7% to +47% (average thus +27%).
In the meantime, many other studies have been carried out and soda loading is considered one of the supplementation measures with the scientifically most broadly supported, performance-enhancing effect.
