Carbohydrate (CHO) and caffeine (CAF) mouth rinsing have been shown to enhance endurance and sprint performance. However, the effects of CHO and CAF mouth rinsing on muscular and cognitive performance in compa https://parcelllabs.com…
In addition to these studies that spanned one to three weeks, several acute-response (single feeding and exercise sessions) studies exist, during which protein was added to a carbohydrate beverage prior to or during endurance exercise. Similarly, most of these interventions also reported no added improvements in endurance performance when protein was added to a carbohydrate beverage as compared to carbohydrate alone . An important research design note, however, is that those studies which reported improvements in endurance performance when protein was added to a carbohydrate beverage before and during exercise all used a time-to-exhaustion test . When specifically interested in performance outcomes, a time trial is preferred as it better mimics competition and pacing demands.
Various nutritional strategies are adopted for athletes to maintain and to improve performance during the competition season. Betaine may enhance performance during a competitive season by increasing the testo…
Resting metabolic rate (RMR) has been examined as a proxy for low energy availability (EA). Previous studies have been limited to adult athletes, despite the serious health consequences of low EA, particularly…
While a great deal of work has focused on post-exercise protein ingestion, other studies have suggested that pre-exercise and even intra-exercise ingestion may also support favorable changes in MPS and muscle protein breakdown . Initially, Tipton and colleagues directly compared immediate pre-exercise and immediate post-exercise ingestion of a mixture of carbohydrate (35 g) and EAAs (6 g) combination on changes in MPS. They reported that pre-exercise ingestion promoted higher rates of MPS while also demonstrating that nutrient ingestion prior to exercise increased nutrient delivery to a much greater extent than other (immediate or one hour post-exercise) time points. These results were later challenged by Fujita in 2009 who employed an identical study design with a different tracer incorporation approach and concluded there was no difference between pre- or post-exercise ingestion . Subsequent work by Tipton also found that similar elevated rates of MPS were achieved when ingesting 20 g of a whey protein isolate immediately before or immediately after resistance exercise.
Sports nutrition supplements
Branched-chain amino acids consist of three amino acids (specifically valine, leucine, and isoleucine) with different chemical structures. These three amino acids are essential for muscle growth. Like other amino acids, these are found in many foods and sold as a powder that you can mix with your water at the gym.
Up to 20 g/day BCAA supplements in divided doses appear to be safe . 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) .
Exercise increases the body’s 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. In theory, free radicals could impair exercise performance by impeding muscles’ ability to produce force, thereby accelerating muscle damage and fatigue and producing inflammation and soreness . Some researchers have suggested that supplements containing antioxidants, such as vitamins C and E and coenzyme Q10 (CoQ10), could reduce this free-radical formation, thereby minimizing skeletal muscle damage and fatigue and promoting recovery .

Sports nutrition degree
While you are in school, you should take every opportunity to learn about the field of dietetics and sports nutrition. This may mean volunteering your time with a school sports team or helping in an athletic department. You can also join organizations specific to the field as a student member to gain more experience. Look into both SCAN (Sports, Cardiovascular, and Wellness Nutrition dietetic practice group of the Academy of Nutrition and Dietetics) and CPSDA (Collegiate and Professional Sports Dietitians Association).
Studying in another country not only allows you to experience the wonders of another culture, but it also broadens your horizons and makes you a stronger citizen in our global society. There are more than 85 countries currently participating in K-State’s education abroad programs!
The first step to becoming a sports dietitian or sports nutritionist is to earn a bachelor’s degree in nutrition. To qualify, the program you choose must be accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).
