Degree in sports nutrition
A career as a sports nutrition professional can be extremely rewarding. It’s important to review different sports nutritionist colleges to make sure you choose the one that’s the best fit with your career goals. You’ll also need to gain professional experience to earn your certification, so you’ll need to make sure the school provides a pathway to meet that requirement. Once you’ve met the sports nutritionist certification requirements, you’ll need to pass the RD exam.
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).
3. Submit transcripts to the FSU Office of Graduate Admissions. Even if courses are posted to another institution’s transcript, we require transcripts from EVERY post-secondary institution you attended. Please have transcripts sent directly from your institution to the FSU Office of Graduate Admissions. If you are a domestic student that attended an institution outside of the U.S., you will be required to provide a credential evaluation for that transcript (please see below regarding credentialing).
Students that are searching for degree programs in sports nutrition are encouraged to select one that is accredited by a nationally recognized accrediting agency such as the Accreditation Council for Education in Nutrition and Dietetics (ACEND). In addition, the program should prepare students to sit for the Board Certified Specialist in Sports Dietetics (CSSD).
It’s no secret that athletes have unique nutritional needs. Good nutrition is critical for athletes who want to perform their best. If you’ve got a passion for sports and an interest in nutrition, you might consider earning a sports nutrition degree.

In conclusion, added protein does not appear to improve endurance performance when given for several days, weeks, or immediately prior to and during endurance exercise. While no ergogenic outcomes may be evident, the scientific literature is consistent in reporting that adding protein to a carbohydrate beverage/gel during exhaustive endurance exercise suppresses markers of muscle damage (creatine kinase) 12 to 24 h post-exercise and decreases the endurance athletes’ feelings of muscular soreness . For these reasons, it seems prudent to recommend for endurance athletes to ingest approximately 0.25 g of protein/kg body weight per hour of endurance exercise (in addition to the athlete’s regular carbohydrate intake) to suppress markers of muscle damage and improve subjective feelings of muscular soreness . Another important consideration relates to the impact of ingesting protein along with carbohydrate on rates of protein synthesis and balance during prolonged bouts of endurance exercise. Beelen and colleagues determined that adding protein to carbohydrate consumption throughout a prolonged bout of endurance exercise promotes a higher whole body net protein balance, but the added protein does not exert any further impact on rates of MPS. While performance outcomes were not measured, these results shift the focus of nutrient ingestion during prolonged bouts of endurance exercise to the ingestion of carbohydrate.
When consumed whole, proteins are digested through a series of steps beginning with homogenization by chewing, followed by partial digestion by pepsin in the stomach . Following this, a combination of peptides, proteins, and negligible amounts of single amino acids are released into the small intestine and from there are either partially hydrolyzed into oligopeptides, 2–8 amino acids in length or are fully hydrolyzed into individual amino acids . Absorption of individual amino acids and various small peptides (di, tri, and tetra) into the blood occurs inside the small intestine through separate transport mechanisms . Oftentimes, products contain proteins that have been pre-exposed to specific digestive enzymes causing hydrolysis of the proteins into di, tri, and tetrapeptides. A plethora of studies have investigated the effects of the degree of protein fractionation (or degree of hydrolysis) on the absorption of amino acids and the subsequent hormonal response . Research indicates that amino acids are absorbed more rapidly when they are consumed as di and/or tri peptides compared to free form amino acids or complete proteins . Further, the rate of absorption may lead to a more favorable anabolic hormonal environment . Calbet et al. examined both amino acid appearance and insulin responses following consumption of protein solutions containing the same amount of protein, or pure carbohydrates. The treatments consisted of a pure glucose solution, whey peptide hydrolysates, and cow’s milk containing milk proteins, lactose and fat. Each of the nitrogen containing solutions contained 15 g of glucose and 30 g of protein. Results indicated that peptide hydrolysates produced a faster increase in venous plasma amino acids compared to milk proteins. Further, the peptide hydrolysates produced peak plasma insulin levels that were two- and four-times greater than that evoked by the milk and glucose solutions, respectively, with a correlation of 0.8 between plasma amino acids and the insulin response in the peptide hydrolysates. One of the inherent shortcomings of this study is that milk proteins are 80% casein and, therefore, are not ideal candidates to compare with hydrolyzed whey.

In addition to direct assessments of timed administration of nutrients, other studies have explored questions that center upon the pattern of when certain protein-containing meals are consumed. Paddon-Jones et al. reported a correlation between acute stimulation of MPS via protein consumption and chronic changes in muscle mass. In this study, participants were given an EAA supplement three times a day for 28 days. Results indicated that acute stimulation of MPS provided by the supplement on day 1 resulted in a net gain of ~7.5 g of muscle over a 24-h period . When extrapolated over the entire 28-day study, the predicted change in muscle mass corresponded to the actual change in muscle mass (~210 g) measured by dual-energy x-ray absorptiometry (DEXA) . While these findings are important, it is vital to highlight that this study incorporated a bed rest model with no acute exercise stimulus while other work by Mitchell et al. reported a lack of correlation between measures of acute MPS and the accretion of skeletal muscle mass.

As a Registered Sports Dietitian and Personal Trainer, I combine fueling your active body with proper training for optimal health and performance in one comprehensive program. I take a holistic stance in your health from a food first, supplements second approach that takes you from poor performance to performance powerhouse!
Athletes need carbs to be at their best. If you don’t get adequate amounts, your energy levels will suffer. This negatively affects not only your physical performance but also your mental performance—causing slower reaction times, poor decision-making, lack of focus, and deterioration of technique (think: throwing, shooting, and running mechanics).9
Urine color isn’t your only indicator of dehydration, though. If you’re working out or competing and start feeling a little confused, get a headache, tire quickly, become dizzy or light-headed when standing up, or feel really moody, these are early warning signs of dehydration. You need to start drinking.
We recommend that athletes eat mostly minimally-processed healthy fats. Aim for a mix of whole-food fats (like nuts and seeds), blended whole foods (like nut butter and guacamole), and pressed oils (like olive and avocado).
By mastering one of these practices every couple of weeks—in order—you’ll be a totally different athlete. And not only that, you’ll have turned your entire eating program around without much hassle or stress.
