Beyond accretion of fat-free mass, increasing daily protein intake through a combination of food and supplementation to levels above the recommended daily allowance (RDA) (RDA 0 https://followmycal.com/74/coindesk/.8 g/kg/day, increasing to 1.2–2.4 g/kg/day for the endurance and strength/power athletes) while restricting energy intake (30–40% reduction in energy intake) has been demonstrated to maximize the loss of fat tissue while also promoting the maintenance of fat-free mass . The majority of this work has been conducted using overweight and obese individuals who were prescribed an energy-restricted diet that delivered a greater ratio of protein relative to carbohydrate. As a classic example, Layman and investigators randomized obese women to consume one of two restricted energy diets (1600–1700 kcals/day) that were either higher in carbohydrates (>3.5: carbohydrate-to-protein ratio) or protein (<1.5: carbohydrate-to-protein ratio). Groups were further divided into those that followed a five-day per week exercise program (walking + resistance training, 20–50 min/workout) and a control group that performed light walking of less than 100 min per week. Greater amounts of fat were lost when higher amounts of protein were ingested, but even greater amounts of fat loss occurred when the exercise program was added to the high-protein diet group, resulting in significant decreases in body fat. Using an active population that ranged from normal weight to overweight (BMI: 22–29 kg/m2), Pasiakos and colleagues examined the impact of progressively increasing dietary protein over a 21-day study period. An aggressive energy reduction model was employed that resulted in each participant reducing their caloric intake by 30% and increasing their energy expenditure by 10%. Each person was randomly assigned to consume a diet that contained either 1× (0.8 g/kg), 2× (1.6 g/kg) or 3× (2.4 g/kg) the RDA for protein. Participants were measured for changes in body weight and body composition. While the greatest body weight loss occurred in the 1× RDA group, this group also lost the highest percentage of fat-free mass and lowest percentage of fat mass. The 2× and 3× RDA groups lost significant amounts of body weight that consisted of 70% and 64% fat mass, respectively.
To date, only a few studies involving nighttime protein ingestion have been carried out for longer than four weeks. Snijders et al. randomly assigned young men (average age of 22 years) to consume a protein-centric supplement (27.5 g of casein protein, 15 g of carbohydrate, and 0.1 g of fat) or a noncaloric placebo every night before sleep while also completing a 12-week progressive resistance exercise training program (3 times per week). The group receiving the protein-centric supplement each night before sleep had greater improvements in muscle mass and strength over the 12-week study. Of note, this study was non-nitrogen balanced and the protein group received approximately 1.9 g/kg/day of protein compared to 1.3 g/kg/day in the placebo group. More recently, in a study in which total protein intake was equal, Antonio et al. studied young healthy men and women that supplemented with casein protein (54 g) for 8 weeks either in the morning (any time before 12 pm) or the evening supplementation (90 min or less prior to sleep). They examined the effects on body composition and performance . All subjects maintained their usual exercise program. The authors reported no differences in body composition or performance between the morning and evening casein supplementation groups. However, it is worth noting that, although not statistically significant, the morning group added 0.4 kg of fat free mass while the evening protein group added 1.2 kg of fat free mass, even though the habitual diet of the trained subjects in this study consumed 1.7 to 1.9 g/kg/day of protein. Although this finding was not statistically significant, it supports data from Burk et al. indicating that casein-based protein consumed in the morning (10 am) and evening (10:30 pm) was more beneficial for increasing fat-free mass than consuming the protein supplement in the morning (10 am) and afternoon (~3:50 pm). It should be noted that the subjects in the Burk et al. study were resistance training. A retrospective epidemiological study by Buckner et al. using NHANES data (1999–2002) showed that participants consuming 20, 25, or 30 g of protein in the evening had greater leg lean mass compared to subjects consuming protein in the afternoon. Thus, it appears that protein consumption in the evening before sleep might be an underutilized time to take advantage of a protein feeding opportunity that can potentially improve body composition and performance.

A successful career in sports nutrition is founded in clinical nutrition, exercise science and counseling and an entrepreneurial mindset and practical experience. Developing this array of skills requires both the right educational background and job experience.
In addition to obtaining the proper education to be considered for open sports nutritionist positions, it’s important to review credential opportunities and requirements. Having your registered dietitian credential is a great place to start, as it establishes your qualifications from the Academy of Nutrition and Dietetics.
The versatility of a PhD or EdD in Kinesiology with a concentration in Sports Nutrition opens the door to several career paths. Graduates of this program are well-prepared to take on leadership roles in a variety of exercise science settings, including:

Sports nutritionists understand the specific dietary needs of athletes. They know the role sport nutrition plays in athletic performance. A sports dietician can work with athletes or sports organizations to recommend and advise on a variety of dietary related areas including:
Sports nutrition supplements
Studies have evaluated beta-alanine as a potential ergogenic aid with a variety of participants, exercise and activity protocols, and dosing regimens. Some studies suggest that beta-alanine consumption could provide small performance benefits in competitive events requiring high-intensity effort over a short period, such as rowing, swimming, and team sports (e.g., hockey and football) that involve repeated sprints and intermittent activity . Other studies have found no such benefits . Evidence is conflicting on whether beta-alanine consumption improves performance in endurance activities, such as cycling . Experts have not reached consensus on whether beta-alanine consumption primarily benefits trained athletes or recreationally active individuals . Studies provide little consistent evidence of a relationship between the dose of beta-alanine and performance effect .
This guide to eating healthy on a budget can be a useful resource, but if you’re a coach who’s working with an athlete, it can also help to understand the problems presented by “food deserts” and “food insecurity.”)
Athlete supplements can provide extra calories, vitamins, and nutrients for your body so it can endure exercise. They can also help build muscles and enhance your performance depending on the activity. For example, there are specific swimming supplements and running supplements, that help keep the muscles fueled, despite completely different muscle movements.
One of the top supplements for athletes is protein powder. There are many types of protein powder on the market, such as whey, casein, egg, pea, hemp, mixed plant, and more. Taking protein powder before you workout can maximize your muscle gain. Athletes often use whey protein products to prepare for competition because they get fast results.
