Effect of caffeine on sport-specific endurance performance: a systematic review. Protein is necessary to build, maintain, and repair muscle. One study in 10 recreationally active, young male cyclists suggested a dose-response relationship [47]. Soy protein lacks the EAA methionine and might lose some cysteine and lysine in processing; rice protein lacks the EAA isoleucine [166]. 7 Endurance Supplements To Boost Stamina And Performance Efficacy: The limited research on the potential ergogenic effects of the BCAAs has found little evidence to date that supplements of these amino acids improve performance in endurance-related aerobic events [75]. Safety: Studies on the safety of vitamins C, E, and other antioxidant supplements taken during exercise show no evidence of adverse effects, aside from potentially reducing some of the benefits of exercise, but such studies have only lasted a few weeks or months. Int J Sport Nutr Exerc Metab 2014;24:14-27. The rationale was the lack of sufficient information to establish that such products could reasonably be expected to be safe and that FDA had never approved androstenedione as a new dietary ingredient permitted in supplements [197]. [, Mora-Rodriguez R, Pallars JG. Plant-based foodssuch as nuts, beans, vegetables, and fortified grain productscontain non-heme iron, which is less bioavailable than heme iron. The amino acid beta alanine is a great supplement to take to boost athletic performance. Increase strength in short-time domain exercises After 7 days of high-intensity cycling sprints, the CoQ10 group had, on average, a significantly smaller improvement in mean power output than the placebo group, suggesting a poorer adaptation to training. Free Radic Biol Med 2016;98:144-58. 2023 Healthline Media UK Ltd, Brighton, UK. Exercise increases the bodys consumption of oxygen and induces oxidative stress, leading to the production of reactive oxygen and nitrogen species (i.e., free radicals) and the creation of more oxidized molecules in various tissues, including muscle. For an individual weighing 154 pounds (70 kg), this dose is equivalent to 210420 mg caffeine. J Appl Physiol 1999;87:2274-83. J Am Diet Assoc 1997;97:765-70. In 2013, FDA declared products containing this ingredient to be illegal after it received 86 reports of deaths and illnesses associated with dietary supplements containing DMAA. [, Cholewa JM, Guimaraes-Ferreira L, Zanchi NE. Pediatrics 2011;127:1182-9. Another 20 were randomized to receive either 300 mg/day androstenedione or a placebo for 6 of 8 weeks while undergoing resistance-training and muscle-strengthening exercises [199]. Food and Nutrition Board. The labels on tart-cherry juice and concentrate products do not usually indicate that they are dietary supplements, although the labels on products containing encapsulated tart-cherry powder do. J Physiol 2016;594:5135-47. FDA has warned against the use of any body- building products that claim to contain steroids or steroid-like substances [214]. Therefore, trained athletes must exert themselves more than untrained individuals to potentially benefit from using the supplement. [, Zhang Y, Coca A, Casa DJ, Antonio J, Green JM, Bishop PA. Caffeine and diuresis during rest and exercise: a meta-analysis. Burke LM. Furthermore, they warn that iron supplementation can cause gastrointestinal side effects. Nutrition and athletic performance: What to consider - Medical News Today People who feel as though they have low energy despite exercising regularly may wish to consider other aspects of their routine before taking supplements. Runner's Diet | Johns Hopkins Medicine [. J Sports Med 2015;6:229-39. Taking too much of some supplements, such as iron, can cause adverse side effects. Anecdotal reactions to creatine use include nausea, diarrhea and related gastrointestinal distress, muscle cramps, and heat intolerance. [, Poortmans JR, Francaux M. Long-term oral creatine supplementation does not impair renal function in healthy athletes. Rimando AM, Perkins-Veazie PM. First, some arginine is converted to nitric oxide, a potent vasodilator that can increase blood flow and the delivery of oxygen and nutrients to skeletal muscle. There were no significant differences between the two groups in measures of strength, torque, or lean tissue mass, demonstrating that glutamine had no effect on muscle performance, body composition, or muscle-protein degradation. Efficacy: Numerous small studies, with and without placebo controls, have investigated Panax ginseng's potential to improve the physical performance of athletes, regular and occasional exercisers, and largely sedentary individuals. [, Wilson JM, Fitschen PJ, Campbell B, Wilson GJ, Zanchi N, Taylor L, Wilborn C, Kalman DS, Stout JR, Hoffman JR, Ziegenfuss TN, Lopez HL, Kreider RB, Smith-Ryan AE, Antonio J. J Int Soc Sports Nutr 2007;4:8. If FDA finds a supplement to be unsafe, it may remove the product from the market or ask the manufacturer to voluntarily recall the product. Effects of cimetidine on caffeine disposition in smokers and nonsmokers. For leucine alone, studies suggest an upper safe limit of intake of 500 mg/kg per day in healthy young and elderly men, or about 38 g/day for a man weighing 75 kg (165 lb) [80-82]. [, de Sousa CV, Sales MM, Rosa TS, Lewis JE, de Andrade RV, Simes HG. All EAAs are necessary to stimulate muscle protein synthesis, so users should select singular or complementary protein sources accordingly. Recent developments in the use of sodium bicarbonate as an ergogenic aid. improved iron status and aerobic capacity in iron-deficient but non- anemic endurance athletes identified 19 studies involving 80 men and 363 women with a mean age of 22 years. Owens JA, Mindell J, Baylor A. 1. Nitrate ingestion: a review of the health and physical performance effects.

Institute of Medicine. [, Quesnele JJ, Laframboise MA, Wong JJ, Kim P, Wells GD. The biggest objection to creatine for endurance athletes is that it's associated with immediate weight gain, typically on the order of about 1 percent or more of your total weight. Effects of betaine on performance and body composition: areview of recent findings and potential mechanisms. Limits foods and beverages higher in added sugars, saturated fat, and sodium. The Australian Institute of Sport supports the use of beetroot juice for improving sports performance in suitable athletic competitions under the direction of an expert in sports medicine, but it notes that more research might be required to understand how the supplement should be used for best results [29]. Beetroot is available as a juice or juice concentrate and in powdered form; the amount of nitrate can vary considerably among products. Safety: Studies have not identified any safety concerns with the consumption of beetroot juice in moderate amounts (about 2 cups/day) for several weeks. Amino Acids 2012;43:25-37. In addition, much of the research on these supplements involves young adults (more often male than female), and not adolescents who may also use them against the advice of pediatric and high-school professional associations [7,15]. JAMA 2003;289:1537-45. Turner, J., & Badireddy, M. (2019). McNaughton LR, Gough L, Deb S, Bentley D, Sparks SA. Implications for use: More research on betaine supplementation to enhance various types of performance, training protocols, and exercise during specific sports is needed before any recommendations for its use can be made [71]. Beetroot juice. 1. Other, usually more expensive, forms of creatine (e.g., creatine ethyl ester, creatine alpha-ketoglutarate, and buffered forms of creatine) have not been proven to have superior ability to creatine monohydrate for enhancing muscle creatine levels, digestibility, product stability, or safety [73,112,123]. Efficacy: Although studies have investigated HMB for two decades, they have used substantially different periods of supplementation (1 day to 6 weeks) and daily doses (1.5 to 6 g; most commonly 3 g based on evidence that this dose provides equivalent results to 6 g and better results than 1.5 g) [61,63,64]. [, Martin WF, Armstrong LE, Rodriguez NR. No effect of acute beetroot juice ingestion on oxygen consumption, glucose kinetics, or skeletal muscle metabolism during submaximal exercise in males. Safety: Studies have not identified any side effects of the fresh tart-cherry juice or concentrate or of supplements of dried tart-cherry-skin powder. Commercial supplements often combine creatine with other substances. In contrast, the International Society of Sports Nutrition (ISSN) concluded from its literature review that beta- alanine supplements (46 g/day consumed for at least 24 weeks) can improve high-intensity exercise performance that lasts over 60 seconds, especially in time-to-exhaustion tasks [54]. Eating a balanced, nutritious diet and getting enough sleep may also boost athletic performance. Efficacy: Although iron deficiency anemia decreases work capacity, there is conflicting evidence on whether milder iron deficiency without anemia impairs sport and exercise performance [12,151,152]. More carnosine in muscle leads to greater potential attenuation of exercise- induced reductions in pH, which could enhance performance of intense activities of short to moderate duration, such as rowing and swimming [52].
