If your state does not require you to be a dietitian in order to work as a sports nutritionist, check their regulations regarding non-dietitian nutritionists. You may still need to earn a graduate degree and seek certain certifications (which we will discuss further below).

Sports nutritionists, or sports dietitians, may provide individual and/or group/team nutritional counseling and education. Depending upon where they work, their goal will be to enhance the performance of athletes, or to improve an individual’s fitness through nutrition. Job duties of a sports nutritionist may include:

Sports nutrition jobs

Becoming certified by organizations recognized by the Institute for Credentialing Excellence can make you more competitive when trying to land a sports nutrition job. An exercise certification through the American College of Sports Medicine is well respected in the field.

Fitness-focused nutrition jobs can be found in many commercial gyms and fitness centers, as well as community centers such as YMCAs. Individuals will need at least a bachelor’s degree in a nutrition program to qualify for this type of job and in some cases a Registered Dietitian is required.

A nutritionist or dietitian working in a fitness setting provides nutrition consultations for members and offers eating plans for weight loss and improved health. In addition, the development of nutrition education programs, creating handouts and writing newsletter articles are all possible duties in this position.

Positive results have also been seen in elite athletes that consume meat-based proteins, as opposed to vegetarian diets . For example, carnitine is a molecule that transports long-chain fatty acids into mitochondria for oxidation and is found in high amounts in meat. While evidence is lacking to support an increase in fat oxidation with increased carnitine availability, carnitine has been linked to the sparing of muscle glycogen, and decreases in exercise-induced muscle damage . Certainly, more research is needed to support these assertions. Creatine is a naturally occurring compound found mainly in muscle. The concentration of creatine in uncooked chicken and beef is approximately 30 mmol/kg (4–5 g/kg), meaning that one serving of beef contains approximately 0.4 g of creatine . Vegetarians have lower total body creatine stores than omnivores, which demonstrates that regular meat eating has a significant effect on human creatine status . Moreover, creatine supplementation studies with vegetarians indicate that increased creatine uptake levels do exist in people who practice various forms of vegetarianism . Sharp and investigators published the only study known to compare different supplemental (powdered) forms of animal proteins on adaptations to resistance training such as increases in strength and improvements in body composition. Forty-one men and women performed a standardized resistance-training program over eight weeks and consumed a daily 46 g dose of either hydrolyzed chicken protein, beef protein isolate, or whey protein concentrate in comparison to a control group. All groups experienced similar increases in upper and lower-body strength, but all protein-supplemented groups reported significant increases in lean mass and decreases in fat mass.

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.

For example, Moore found that muscle and albumin protein synthesis was optimized at approximately 20 g of egg protein at rest. Witard et al. provided incremental doses of whey protein (0, 10, 20 and 40 g) in conjunction with an acute bout of resistance exercise and concluded that a minimum protein dose of 20 g optimally promoted MPS rates. Finally, Yang and colleagues had 37 elderly men (average age of 71 years) consume incremental doses of whey protein isolate (0, 10, 20 and 40 g/dose) in combination with a single bout of lower body resistance exercise and concluded that a 40 g dose of whey protein isolate is needed in this population to maximize rates of MPS. Furthermore, while results from these studies offer indications of what optimal absolute dosing amounts may be, Phillips concluded that a relative dose of 0.25 g of protein per kg of body weight per dose might operate as an optimal supply of high-quality protein. Once a total daily target protein intake has been achieved, the frequency and pattern with which optimal doses are ingested may serve as a key determinant of overall changes in protein synthetic rates.
