LACTAT BUFFER di SPONSER® è una bevanda in polvere dal sapore delicato con citrato di sodio e bicarbonato per gli sport ad alta intensità, i cosiddetti sport anaerobici lattico-acidi. Durante gli esercizi fisici ad alta intensità, l'acidificazione muscolare e il conseguente accumulo di lattato come anche il calo a breve termine del pH del sangue sono spesso fattori che limitano le prestazioni. L'atleta diventa "acido" e limitato nella sua capacità di prestazione. LACTAT BUFFER fornisce una migliore "capacità tampone acido" e quindi una maggiore tolleranza al lattato. Ciò significa che l'atleta con la sua tolleranza individuale al lattato, che è stata sviluppata attraverso l'adattamento dell'allenamento, può sopportare un carico più a lungo o raggiungere una prestazione più elevata nello stesso tempo.
Quali tipi di sport approfittano?
-tipico stress anaerobico lattico-acido:
nuoto, atletica leggera (breve e medie distanze), canottaggio, sci, sci di fondo (sprint)
-sollecitazioni di intervallo ripetitive:
vari sport di squadra (calcio, hockey), sport di forza, arti marziali (karate, judo)
Funzione ed effetto del caricamento della soda
L'integrazione con LACTAT BUFFER, o bicarbonato di sodio e/o citrato è anche chiamata soda-loading. Se il bicarbonato di sodio e il citrato di sodio vengono utilizzati con carichi anaerobici ad alta intensità da circa 1 a 10 minuti, si possono prevedere miglioramenti significativi delle prestazioni.
Più è pronunciata l'acidosi metabolica indotta dal carico (acidosi), più il miglioramento delle prestazioni sembra essere pronunciato. In pratica, ciò significa che lo stress anaerobico andrà a beneficio degli atleti abituati come i corridori di media distanza, i vogatori, i nuotatori, gli sciatori, ecc. molto di più da un'integrazione rispetto, ad esempio, agli atleti abituati alla resistenza come i corridori di lunga distanza, i triatleti o i ciclisti. Questo perché negli sport anaerobici viene allenata una tolleranza al lattato significativamente più alta che negli sport di resistenza. Un altro gruppo di atleti che possono potenzialmente beneficiare del caricamento di soda sono quelli con carichi ad intervalli ripetitivi. Questo vale per molti sport di squadre, di palla e da combattimento.
Il caricamento di soda è interessante anche per gli atleti di forza, poiché l'allenamento isolato di alcuni muscoli produce livelli di lattato localmente molto elevati, che devono essere rimossi il più rapidamente possibile. Se il muscolo rimane acido per troppo tempo, il set successivo non può essere completato abbastanza rapidamente e non con un carico sufficiente. Tuttavia, poiché il caricamento della soda significa anche un aumento dell'apporto di sodio, l'integrazione nell'allenamento con i pesi non dovrebbe essere effettuata in modo permanente, ma dovrebbe essere riservata a specifiche fasi intensive. Lo stesso vale per gli sport in cui ogni settimana si svolgono una o più gare.
A causa dell'effetto di un aumento del tampone bicarbonato nel sangue, non è necessariamente il valore di lattato individualmente ottenibile dell'atleta che viene aumentato, ma soprattutto la tolleranza al lattato. Questo significa che l'atleta con il suo valore individuale di lattato può resistere più a lungo a un carico o avere prestazioni migliori. L'atleta non prova necessariamente il carico percepito come inferiore se si vuole ottenere il massimo rendimento raggiungibile in gara. Al contrario, una prestazione data e definita dovrebbe essere percepita come meno stressante. In tutti i casi, ci si deve aspettare un recupero significativamente più rapido, perché la rimozione dell'acido è accelerata dall'aumento della capacità del tampone. Ciò significa una più rapida scomparsa della sensazione di muscolo "rigido" dopo lo sforzo e un recupero più rapido.
Già nel 1993, una prima meta-analisi ha esaminato 29 studi di atleti con carico di soda. Nel complesso, le prestazioni fino all'esaurimento sono aumentate massicciamente con una media del 27%. Tuttavia, a causa della diversità dei disegni dello studio, c'è stata anche un'ampia variazione del +/-20%. Nel frattempo, sono stati effettuati molti altri studi e il caricamento della soda è considerato una delle misure di integrazione con l'effetto di miglioramento delle prestazioni scientificamente più ampiamente supportato.
Dosaggio e assunzione
In passato, il carico acuto di soda era praticato circa 3 ore prima della competizione, che era una dose enorme quando si prendeva 0,3-0,5 g di bicarbonato di sodio e/o citrato per kg di peso corporeo e molto spesso portava a problemi gastrointestinali. Secondo gli ultimi risultati dello studio, l'integrazione viene effettuata nell'arco di diversi giorni. In questo modo si possono evitare i problemi di tolleranza di una dose singola elevata.

Nutrition in ice hockey: what ice hockey players should be aware of
Ice hockey is a fascinating sport: fast-paced, physical and in some cases highly dramatic. Although the regular match time is usually three times 20 minutes with breaks of 15 minutes, the effective play time is much longer. Depending on the interruptions during the game, the five field players and the goalie can spend up to two and a half hours on ice. It is obvious that a competition of over two hours requires a targeted and carefully balanced nutritional strategy if an athlete is to fully exploit his performance potential on the ice. We explain in the following what ice hockey players nutrition-wise need to consider before, during and after the competition and make recommendations for product selection from the SPONSER range.
Filling glycogen stores
Full energy reservoirs are the be-all and end-all in a sport with long performing times such as ice hockey. Studies confirm that glycogen supercompensation (carboloading) with a concentrated, carbohydrate-containing drink provides a considerable energy advantage on the day before the competition. Suitable products:
• CARBO LOADER: High energy sports drink for replenishing glycogen stores, contains Vitargo®, a barley starch hydrolysate specially developed for this purpose.
• LIQUID ENERGY GELS: Those who prefer it quick and comfortable can take carbohydrates directly from the tube with these gels. They deliver easily tolerable energy, which is available within a few minutes after ingestion.
• HIGH ENERGY BAR: Competition bars for long-lasting energy. Ideal up to one hour before use.
Increased lactate tolerance
The relatively short, but high-intensity blocks, with sprints and hardly any breathers, as they occur again and again in ice hockey, result in high lactate accumulation. Beta-alanine and soda loading (sodium bicarbonate and sodium citrate) in advance increase the extracellular buffer capacity, which in turn delays the muscle acidosis and fatigue. Athletes benefit also from creatine supplementation, especially when it comes to speed and interval performance - two factors that play a central role in ice hockey. Suitable products:
• LACTAT BUFFER: For professional soda loading during 4-5 days before important games.
• BETA ALANINE: In contrast to soda loading, it does not increase the extracellular but the intracellular buffer capacity and thus ideally complements the LACTATE BUFFER. Loading is necessary for approx. 8 weeks and should be paused after approx. 12 weeks for several weeks.
• CREATINE MONOHYDRATE: Loading phase during 1-2 weeks, but can also be used throughout the entire season. For even better absorption, a combination with CREATINE PYRUMAX is also possible.
DURING THE GAME
Ensure regular liquid supply
Despite the obviously cool temperatures on the ice field, the loss of liquid is significantly higher than one would expect, due to high-intensity performance and the hindered thermoregulation by full-body clothing and protection gear. For this reason, professional athletes make sure to drink 0.5 to 1 litres of an energy- and electrolyte-containing sports drink per hour during a match. Suitable products:
Avoiding blood sugar fluctuations and muscle cramps
In competitive sports, energy supply plays a central role because the body's fuel stores are not sufficient for a duration of more than approx. 90 to 120 minutes. LIQUID ENERGY Gels can therefore also be used in addition to carbohydrate-electrolytes drinks. They provide fast energy, can be taken easily and do not strain the digestion. Players with high sweat losses and/or cramp tendency may benefit from our MUSCLE RELAX Shot. Suitable products:
• LIQUID ENERGY GELS: Best tolerated liquid energy concentrate from quick and slow available carbohydrates. The energy kick par excellence! With or without caffeine.
• MUSCLE RELAX: 30 ml bottles of cucumber juice and vinegar. At first signs or acute muscle cramps, rinse your mouth briefly with it and drink afterwards.
Keeping coordination and concentration high
Reaction time, attention, coordination, concentration and a high focus are elementary performance components in a technical and fast discipline like ice hockey. Suitable products for increased cognitive performance and delayed fatigue:
• ACTIVATOR: Ready-to-drink flask with 200 mg caffeine from guarana, mate and green tea. Ideal from the second third or to manage mental fatigue. To be taken approx. 30-60 min before the desired time of effect. Take in two portions depending on tolerance.
• MENTAL FOCUS: Caffeine-free formulation with green tea active ingredients and Rhodiola Rosea. Promotes focusing without increasing anxiety.
Ensure fast recovery
«After the match is before the match» is a bon mot in ice hockey. It is therefore crucial to take care of regeneration immediately after a match. A high-quality regeneration supplement supplies the body with fluid and electrolytes, fills the glycogen stores and repairs endured muscle damage. Suitable products:
• RECOVERY DRINK: Fruity regeneration drink, lactose-free. Preparation with water.
• PRO RECOVERY: Efficient, highly professional protein-based regeneration product to balance muscle stress. Lactose-free and without artificial sweeteners. Preparation with water.
• NITROFLOW PERFORMANCE2: The professional tip! Its vasodilatory effect enables better nutrient supply and reduction of metabolic end products (e.g. lactate). Ideal for supporting regeneration.

All you need to know about sports nutrition in tennis
During the short breaks after the sets you can see cracks like Roger Federer eating half a banana and or having a drink from time to time. Does a tennis athlete need specific sports nutrition and if so, what do you need to know?
Short breaks on the court
Numerous, but short breaks during sets mean that sports nutrition in tennis has to meet special needs: Sports nutrition must not only be consumable quickly, but must also be as tolerable as possible. So if you see tennis stars eating half a (ripe) banana during the sets, there is nothing wrong with that. For a match lasting several hours, however, this snack is definitely not enough.
Tennis players can therefore rely on liquid energy from the tube, for example with a LIQUID ENERGY GEL (with or without caffeine), a high-quality, carbohydrate sports drink such as COMPETITION, LONG ENERGY or ISOTONIC or a few bites of a HIGH ENERGY BAR. In search of a noticeable caffeine kick that reawakens motivation and concentration, we recommend an ACTIVATOR ampoule or a few POWER GUMS out of the bag. The previous and regular use of MENTAL FOCUS can offer clear advantages in terms of cognitive performance both in technical training and in competition.
Indoor or outdoor
From a nutritional point of view, it makes no difference whether a tennis match is played indoor or outdoor on sand, grass or hart court. However, the climatic conditions can vary significantly and thus have a corresponding influence. Temperature and humidity are central parameters that must be taken into account when eating on the tennis court. In the cold and in low humidity, nutrition has primarily to cover the energy demands of an athlete. In the heat or in great humidity the body needs considerably more liquid. If matches over three, four or sometimes five sets including tie-break are expected, a carboloading two days before the competition is recommended. If the heat on the court is high, a previous soda loading with LACTAT BUFFER can be very useful. Players with a high sweat rate and a tendency to cramp additionally use SALT CAPS or MUSCLE RELAX shots.
Regeneration during tournaments
In tennis tournaments lasting several days or even two weeks, regeneration plays an important role. The recommendations are therefore: Regular carboloading with CARBO LOADER, every second or third day. In hot and humid regions, soda loading with LACTAT BUFFER is recommended to increase sodium levels and thus prevent dehydration and cramps. Always take a carbohydrate-protein shake such as PRO RECOVERY after every match and additionally consume a protein shake MULTIPROTEIN or CASEIN in the evening before going asleep. If frequent travel and/or contact with large crowds is necessary, the use of IMMUNOGUARD prevents the risk of infection.

Soda loading with LACTAT BUFFER increases the lactate tolerance in high-intensity sports
Muscle hyperacidity and the consequent accumulation of lactate as well as a short-term drop in blood pH are performance-limiting factors when it comes to high-intensity training and competition. The athlete becomes «acidic» and therefore limited in his performance. In this situation, sodium citrate and sodium bicarbonate offer great benefits. SPONSER sells both ingredients in its beverage powder LACTAT BUFFER.
Soda loading: function and benefit
Supplementation with LACTAT BUFFER or sodium bicarbonate and/or citrate is also called «soda loading». If sodium citrate and sodium bicarbonate are used in high-intensity sports that last from approx. 1 to 10 minutes, significant performance improvements can be expected. The greater the anaerobic-lactacid load, and thus the more pronounced the induced metabolic acidosis, the more effective an increased buffering capacity may improve performance.
Which sports benefit?
In practice, this means that athletes such as middle distance runners, rowers, swimmers, alpine ski athletes etc. benefit significantly from this specific kind of supplementation. More than, for example, endurance athletes such as long-distance runners, triathletes or cyclists. This is because anaerobic sports train significantly higher lactate tolerance than endurance sports. Another group of athletes that potentially benefits from a soda loading is the one working 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.
Increased lactate tolerance, improved acid buffer capacity
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.
Studies prove effectiveness
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.
Dosage and intake
In the past, soda loading was practiced about 3 hours before the competition, which was an enormous dose when taking 0.3-0.5 g sodium bicarbonate and/or citrate per kg body weight. This led to gastrointestinal problems very often. According to the latest study findings, supplementation is now carried out over several days. Thus, the tolerance problems of a high single dosage can be avoided.
Ideally, LACTAT BUFFER should be consumed 3-5 days before the competition, spread over the day as recommended, with the last dose being taken 3 hours before the start at the latest. Interestingly, the performance-enhancing effect of this multi-day intake strategy seems to last up to 2 days after discontinuation of supplementation. This is accordingly important for sports events lasting several days.
Combined increase of intra- and extracellular buffer capacity
Many studies about supplementation to increase intra- and extracellular buffer capacity haven been published so far; with many different intake profiles and forms of workouts. As expected, and as explained above, the greatest benefit is achieved with highly intensive loads of 1 to 10 minutes duration. Such forms of performance produce the highest acidosis in the musculature and consequently in the blood. In order to achieve maximum benefit in the anaerobic-lactacid performance range, the increase in extracellular buffer capacity through soda loading can be combined with an increase in intracellular buffer capacity through beta-alanine. The combination of these two measures can lead to an additional increase in performance, at least if chronic soda loading is carried out (approx. 3-4 days before the competition). Since the intake of BETA-ALANINE also requires a chronic intake for about 8 weeks in order to increase the body's own carnosine stores, such an intake strategy does not give rise to any tolerance problems compared to acute intake on the day of the competition.
