Nutritional InformationNutritional needs will be broken down into Macronutrients and Micronutrients, which are equally as important to your nutritional needs. In this section they both will be defined and given specific requirements for a collegiate softball player.

Macronutrients

Macronutrients are significantly important to one’s diet, and there are three kinds: carbohydrates, protein and fats.

Protein

Protein is the primary structure for every cell in the human body, they are essential for growth and development. Protein is composed of carbon, hydrogen, oxygen and nitrogen. They are made up of Amino Acids, which means nitrogen containing. There are twenty different kinds that are broken down into essential, non-essential and conditionally essential. The higher quality proteins are easier to digest such as animal products of eggs, dairy, meats, fish and proteins. Soy and other plant based proteins contain the correct essential amino acids but are less digestible. While the average protein intake for adults is .80 grams (per kg of bodyweight) of good-high quality proteins, being an athlete you should get between 1.2-1.7 grams per kilogram of bodyweight. Another way of measure how much protein should be eaten in a diet is between 10-35%, being an athlete it should be on the higher side of that.

Carbohydrates

Carbohydrates are the PRIMARY source of energy, it is not however an essential nutrient because it can be broken down and made from amino acids. This should be a large energy source for you being an athlete. They are composed of carbon, hydrogen and oxygen. Carbohydrates are broken down into sugar molecules, in which there are three. Monosaccharides are the simplest form of sugar, examples is glucose, fructose, and galactose. Disaccharides are made of two sugar molecules such as sucrose, lactose and maltose. Polysaccharides are made up of three or more sugar molecules like starch, fiber and glycogen. Glycogen is the stored form of sugar, and is commonly found in the liver and muscles. This means you will always have stored energy.

Fats

Fat or lipids is the other form of energy. It is also made from carbon, oxygen and hydrogen, but because of the fatty acid chains it has more carbon and hydrogen compared to the oxygen which is where the energy comes from. There are multiple forms of fats. Saturated fat is one of the worst kinds, with no double bonds and is solid at room temperature. they are used for structural functions and physiological functions. There is no daily requirement for saturated fats. There are a few unsaturated fats, they have some carbon and are joined by double bonds. When they only have one double bond it is called monounsaturated fat, and with two or more is called polyunsaturated fat. Examples of essential fats that are polyunsaturated is omega-6 and omega-3 fatty acids. Omega six is found in soy, corn, safflower oil. Omega-3 is found in fatty fish like salmon, herring, halibut, trout and mackerel. Stored energy from fat is found in adipose tissue. Fat is also associated with cholesterol. There is two kinds of cholesterol, low density lipoproteins or LDLs and high density lipoproteins or HDLs. LDLs are associated with heart disease and HDLs are protective against heart disease.

Micronutrients

Micronutrients are required in the diet in small doses in order for survival. I will talk about vitamin and minerals.

Vitamins

Vitamins are organic substances needed in small doses to perform metabolic activities. There are water soluble such as vitamins B and C. This means they dissolve in water and are transported in the blood. What is not needed of vitamins is excreted in the urine. There are also fat soluble vitamins which are carried in fat in the blood and stored in fat tissues, such as vitamins A, D, E and K.

4

Minerals

Minerals are also small and contribute to metabolic functions but contribute to bone, teeth and nails more often. This also includes electrolytes of sodium, potassium and chloride. However there are two very important minerals for athletes, Iron and Calcium. Iron is essential for hemoglobin (protein in the blood), iron is important for growth, development, cell functioning and syntheses or functioning of hormones. When low in Iron, an athlete could become anemic causing some complications such as fatigue, irritability, poor concentration, headache, hair loss and more. Women are more susceptible to this. Another important mineral is Calcium. Calcium is important to bone growth and important for proper muscle function.

HydrationHydration is something an athlete should worry about at all times, including while at practice. A loss of even 2% of bodyweight can have affect athletic performance. Intake of water should be between 3.7-2.7 Liters of fluids per day for both men and women. In addition to fluids athletes should also be concerned about their electrolyte intake which includes magnesium, sodium, potassium, chloride and calcium. This is because a lot of sodium is lost in sweat loss. This can be found in sports drinks. During exercise of over sixty minutes a person should intake nine ounces of cold water or salted beverage, every twenty minutes. After an athlete should have had 1.5 liters over twelve hours after their workout.

How to Find My Own NeedsEach person can find out how many of each macronutrient they need base off of their height, weight and activity level, here’s how.

First find Ideal bodyweight. For females start at 5 foot, is around 106 pounds, and for every inch you are add 6 more pounds to that. For example, if you are 5’6” your ideal weight is 142 lbs. Now subtract your actual weight from your ideal weight. If I am 155 lbs, my ideal weight is 142 lbs, the total is 13. Multiply that number (13) by 25%. That is how much muscle in your body. Add that number to your ideal weight that equals the weight you should use. For example 142+3.25=145.25lbs. To see if you need to adjust your weight divided that number by ideal, and if it is over 130% then you need to use your ideal body weight and not your adjusted body weight. For example 145.25/142=102%, so I will use my adjusted body weight.

Next we will find total energy needs using mets. Play softball for one hour is roughly a 5.9, multiply that by how long you play and by weight in kilograms. (Weight from pounds to kilograms, is to take weight in pounds and divide by 2.2) For example: 5.9 x 2 hrs x 66kg=779 calories burned. Now roughly do a rest of the day activity, an example 1 MET x 22 hrs x 66kg=1452 calories burned the rest of the day. Add those together for total energy needs, 779+1452=2301.

Another way for total energy needs is using the Harris-Benedict equation; this is the amount of calories if you did nothing for a whole day. For females the equation is 655.09 + (9.53 X weight in kg) + (1.84 X height in cm) – (4.67 X age). An example would be: 655.09 + (9.53 x66) + (1.84 X 167.64) – (4.67 X 22) = 1490 calories per day. From there take this number and multiply it by an activity factor. This should be your best guess off the chart below; I will use 1.5 for this example. It should look like this: 1490 x 1.5 = 2235. For a better estimate use the total energy needs from mets and average it with this one, like so; (2235 + 2301)/2 = 2268.

From there we will break this average calorie need into Macronutrients. For an athlete of your type you should consume at minimum 50% of it carbohydrates, 25% protein and 25% fats. From the example being used it should look like this, Carbs: 1134, Protein: 567 and Fats: 567. From there we can break it down into grams per serving, there is four grams per serving in both carbohydrates and proteins, and nine grams for fats, it should be something like this; Carbs: 284 grams, Protein: 142 grams and Fats: 63 grams. If you do not want to measure in grams you can do servings, there is 15 grams of carbs in one serving, 7 grams of protein in one serving of protein and 5 grams per serving of fats; it will look something like, 19 servings of carbs, 20 servings of protein and 12 servings of protein. Refer to chart below for suggestions of both.

Nutritional Week PlanWhen planning your week, you need to look ahead to what activities are coming up. If you are in post season, and are lifting and conditioning 4 days a week, you need to make sure nutritional and hydration needs are met. Things to look at is should you carbohydrate load before a hard workout or a game, or just get enough of your protein in after you workout. It is also important that you eat your protein with a carbohydrate after working out; the carbohydrate-protein ratio should be 3:1. Another way to look at this is that you should consume 1.0-1.85g of carbohydrates per kilogram of bodyweight between 15-60minutes after exercise and continue through five hours. Also 20-30grams of protein should be eaten every 3-4 hours.

As mentioned above an option is carbohydrate loading. Carbohydrate loading is when an athlete will increase carbohydrates, in order to store them as glycogen to later use them as energy in their competition. This could be done before game day, competition day of practice or when exercise will last longer than 90 minutes. It can be done by starting two or three days prior, exercising with little to no carbohydrates, followed by three days of rest while eating carbohydrates. However participating in carbohydrate loading can increase injury, so be very careful.

Carbohydrates seem to dictate the diet for an athlete so there are more important things to think about when taking carbohydrates. The best type of carbohydrate for an athlete is a mixture between high and low glycemic indexes. High glycemic index is best for an athlete immediately following a workout, this means it will digest quickly and typically is higher in sugar. High glycemic index carbs should not be taken prior to 45 minutes of exercise. Low glycemic index carbohydrates breakdown over time to digest slowly, and are perfect for the rest of the diet. As briefly mentioned in the hydration section, you should also be ingesting high glycemic carbohydrates during prolonged exercise.

8

SupplementsThere are thousands of supplements on the market; the best way to tell what is legal or not legal is to check with the NCAA or your athletic trainer. However, many supplements are legal, like protein bars, protein powders, beverage mixes for hydration, and creatine. This does also include vitamins and minerals. At has been said that many females could benefit from an iron supplement but is by no means required. It is always important to ask a doctor or athletic trainer before taking any supplements. A common supplement is caffeine which can help with muscle twitch fibers, and some athletes says it “hypes” them for the workout ahead, however you only need 3-9mg/kg of body weight.
