How to Optimize Racehorse & Camel Performance: A Guide to Energy, Muscle, and Stamina Supplements

In the high-stakes worlds of Thoroughbred racing and Middle Eastern camel racing, the margin between victory and defeat is often measured in fractions of a second. For veterinarians and breeders, optimizing performance is not merely a matter of training volume; it is a sophisticated exercise in applied exercise physiology and nutritional biochemistry. While the fundamental principles of energy production and muscle contraction are conserved across mammalian species, the athletic horse (Equus caballus) and the racing dromedary (Camelus dromedarius) possess distinct metabolic adaptations that dictate how they respond to ergogenic aids.

The global market for equine and camel performance supplements is vast, yet the scientific evidence supporting many products remains uneven. A foundational tenet of sports nutrition is that nutritional ergogenic aids are generally less efficient at improving physical ability than an appropriate training regimen . However, for elite athletes training at the limits of their physiological capacity, small nutritional variations can be the difference between finishing first or in the middle of the pack . This guide provides a professional, evidence-based framework for evaluating energy, muscle, and stamina supplements for these unique athletes, with a focus on practical application and regulatory safety.

The Physiological Basis of Performance

To prescribe supplements rationally, one must first understand the energetic demands of the race. The athletic horse relies on a blend of aerobic and anaerobic metabolism. During high-intensity sprinting, muscle glycogen is rapidly depleted, leading to the accumulation of lactic acid and the onset of acute fatigue . The racing camel, by contrast, presents a unique physiological profile. Camels have lower energy requirements for locomotion, a higher glucose supply, and a preferential dependence on slow-twitch muscle fibers that rely on aerobic metabolic pathways . This allows camels to perform muscular functions at intensities that exceed the ability of horses over their traditional race distances (which can range from 5 to 40 km) . Consequently, the supplement strategy for a camel often prioritizes aerobic efficiency and thermoregulation, while a racehorse may require targeted support for anaerobic power and acid-base balance.

Energy Supplementation: Fueling the Fire

Energy is the currency of performance. While base diets provide the bulk of calories, targeted supplementation can manipulate metabolic pathways to spare glycogen, enhance mitochondrial function, and delay fatigue.

Dietary Fat and Glycogen Sparing

The concept of fat adaptation involves feeding a high-fat diet alongside interval training to enhance mitochondrial oxidation of fatty acids, thereby sparing the use of muscle glycogen and glucose . Research on Thoroughbreds has demonstrated that a fat-supplemented diet can increase pre-exercise muscle glycogen concentrations, with significant increases observed by Day 21 of supplementation . This glycogen-sparing effect is critical for delaying the onset of fatigue during high-intensity exercise . However, the response is adaptive; in horses not yet adapted to fat feeding, fat supplementation may initially slow the rate of muscle glycogen repletion post-exercise . For camels, traditional polyunsaturated oils have a slow metabolism and limited use in short-distance, anaerobic races, whereas tropical oils rich in medium-chain fatty acids, such as coconut oil, are more readily absorbed and provide an available source of “cool” energy .

Carnitine and Mitochondrial Support

L-Carnitine is an amino acid derivative responsible for the transport of long-chain fatty acids into the mitochondria for beta-oxidation. In both horses and camels, continuous carnitine supplementation has been shown to increase muscle glycogen content and the proportion of oxidative type IIA muscle fibers, favoring aerobic metabolism . By enhancing the efficiency of fat utilization, carnitine supports endurance and reduces the reliance on carbohydrate stores.

Muscle Development, Power, and Buffering

Muscle mass, fiber type composition, and the capacity to buffer metabolic byproducts are primary determinants of power and stamina. The supplement market offers several compounds aimed at these targets, but the evidence base varies significantly.

Beta-Alanine and Carnosine Buffering

Beta-alanine is the rate-limiting precursor for the synthesis of carnosine, a dipeptide stored in skeletal muscle that acts as an intramuscular buffer against lactic acid accumulation. Studies in Thoroughbreds have confirmed that oral beta-alanine supplementation can increase carnosine concentrations in types I, IIA, and IIB skeletal muscle fibers . This increase in muscle carnosine leads to enhanced intramuscular buffering capacity, potentially delaying the onset of fatigue without elevating total carbonate (TCO2) levels, thus avoiding breaches of racing rules . The supplementation protocol typically requires a loading phase of at least four weeks to achieve significant effects .

Creatine: Energy Currency and Aerobic Capacity

Creatine plays a critical role in the immediate energy system by converting ADP back to ATP. While early research suggested no ergogenic benefit in horses, more recent studies indicate that long-term creatine supplementation may improve aerobic capacity and have a beneficial effect on equine athletic performance . However, the scientific consensus remains mixed, with some reviews concluding there is little robust evidence for its efficacy in horses . For camels, creatine is recognized as a supplement to increase energy storage, alongside dimethylglycine (DMG) and trimethylglycine (TMG) .

HMB and Muscle Protein Metabolism

β-Hydroxy β-methylbutyrate (HMB) is a metabolite of the amino acid leucine that has garnered attention for its potential to influence muscle satellite cells and gene expression related to skeletal muscle growth . Supplementation in Thoroughbred geldings has been shown to increase the percentage of type IIA muscle fibers in the gluteus medius, although this alteration in fiber composition did not consistently translate into improved performance in all studies . HMB may be most valuable during periods of intense training or recovery from injury, where its anti-catabolic properties can help maintain muscle mass.

Antioxidants, Cellular Protection, and Recovery

Intense exercise increases the production of reactive oxygen species (ROS), which can lead to oxidative damage of muscle cells and impaired performance. Antioxidant supplementation is a cornerstone of recovery strategies.

Vitamin E and Selenium

Vitamin E and selenium act synergistically as powerful antioxidants, protecting cellular membranes from lipid peroxidation and guarding against a buildup of free radicals in the body . In racing camels, deficiencies in vitamin E and selenium have been linked to poor racing performance, stiff gait, lethargy, and reduced fertility . Furthermore, soils and plants in the Arabian Peninsula are often deficient in selenium and copper, making supplementation particularly important for camels in the UAE . Vitamin E is also often lacking in the performance horse’s diet, especially when fed high-cereal diets, and deficiencies have been associated with reduced stamina and tying-up . A balanced Vitamin E and selenium supplement is therefore recommended for hard-working horses and camels, particularly during intense training and competition .

Electrolytes and Hydration

Sweating is the primary mechanism for thermoregulation during exercise, but it results in the loss of essential electrolytes—sodium, potassium, calcium, and magnesium—which can lead to fatigue and impaired muscle function if not replaced . Electrolyte supplementation is indicated whenever an animal has sweated significantly or has moderately sweated day after day in hot weather . The best practice is to administer electrolytes in the feed to ensure accurate dosing . Pre-loading one hour before travel and post-competition supplementation are recommended to aid recovery and stimulate thirst . For camels, which lose liquids and electrolytes during exercise, intensive training, and heat stress, specialized electrolyte liquids are available to prevent metabolic disorders and loss of appetite .

Species-Specific Considerations: The Camel

The racing camel presents unique nutritional challenges. Camels are pseudo-ruminants, and while they perform well on traditional diets of alfalfa and barley, they are prone to digestive upset, including colic and rumen dysfunction . A significant research gap exists for specific nutritional requirements in dromedary camels, and management practices are often extrapolated from cattle or horses .

Rumen Undegradable Protein (RUP)

Recent research from the UAE has investigated the role of rumen undegradable protein (RUP) in racing camels. A 17-week study found that increasing dietary RUP by 57% via roasted soybean meal may benefit racing performance, with statistical trends observed in speed, heart rate, and rectal temperature . This suggests that optimizing the protein fraction that bypasses rumen fermentation to be absorbed in the small intestine can support muscle development and recovery in exercising camels.

The Regulatory Imperative: Anti-Doping and Contamination Risks

For veterinarians and breeders, the selection of a supplement is as much a regulatory decision as a nutritional one. The use of performance-enhancing drugs is strictly prohibited in both horse racing (under FEI and national rules) and camel racing in the UAE .

The FEI Prohibited Substances List

All ingredients in a supplement must be checked against the FEI’s Equine Prohibited Substances List (EPSL) . The list is divided into Banned Substances, which are prohibited at all times, and Controlled Medication, which are permitted for therapeutic use under specific conditions . The responsibility for ensuring a product is free from prohibited substances lies with the Person Responsible (PR) .

The Risk of Contamination

A critical concern is that supplements, including herbal and natural products, may contain prohibited substances that are not disclosed on the label . In human sports, reported contamination of nutritional supplements is estimated at between 10% and 25% . The FEI has issued repeated warnings that a contaminated supplement will not excuse a positive doping test, and sanctions will be imposed regardless of intent . Therefore, sourcing products from reputable manufacturers with rigorous quality control and batch testing is essential. The use of all supplements should be meticulously recorded in an animal’s medical logbook .

Conclusion

Optimizing the performance of racehorses and camels through nutritional supplementation is a nuanced discipline. The evidence supports targeted interventions for energy provision (fat adaptation, carnitine), muscle buffering (beta-alanine), and cellular protection (vitamin E, selenium, electrolytes). However, the scientific literature also cautions against the indiscriminate use of ergogenic aids, emphasizing that appropriate training and a balanced base diet remain the foundation of athletic success. For the veterinarian and breeder, the imperative is to critically evaluate the evidence for each supplement, consider the unique physiology of the species, and remain vigilant regarding anti-doping regulations. In an industry where margins are slim and integrity is paramount, an evidence-based, risk-managed approach to supplementation is not just a performance strategy—it is a professional obligation.
