Diet and Your Race
Physio Logic’s medical nutritionist, Michelle Miller, MSACN, discusses methods to decide the correct quantity of carbohydrates, proteins and fat it’s essential run your finest race.
What do I eat?
By now you could be realizing that what you’re going to eat on a coaching day will most likely differ from the day if you run 26.2 miles. That is completely right.
Carbohydrates
Muscle glycogen is used probably the most quickly in the course of the first phases of train. And also you guessed it, you’re going to wish to ensure you’ve obtained sufficient inventory. That is the one nutrient that can be utilized for anaerobic vitality manufacturing and creates vitality for muscle contractions as much as 3x quicker than fats.
There’s a robust affiliation between glycogen (storage type of glucose which is derived from carbohydrates) and fatigue.
So what’s the function of carbohydrates throughout exercise?
Carbs energy contractile proteins of muscle and gas the mind and the central nervous system. It is usually essential to notice that carbs spare protein by minimizing gluconeogenesis (which is when proteins are oxidized for gas…not very best).
So how a lot do you want?
Effectively, that depends upon YOU!
We assess carbohydrate wants based mostly on grams per kg of physique weight. Particular wants fluctuate with kind of train, depth, length and gender. The aim is to match glycogen shops and blood glucose to gas calls for of train.
To notice: kg = lbs/2.2
Coaching day carbs: 3-5g/kg for low depth (shorter coaching days)/ 8-12g/kg for very excessive depth.
Ex. If you’re 150 lbs, you’re roughly 68 kg (150 lbs divided by 2.2). If it’s a gentle coaching day you could think about 4g/kg. So 4g/68kg= 272g of carbohydrates.*

Timing Your Carbohydrate Consumption
Earlier than your occasion: Sooner or later between 1-4 hours earlier than your occasion, prime off shops with 4g/kg of carbohydrates.
Ex. If you’re 150 lbs, you’re roughly 68 kg (150 lbs divided by 2.2). If that is your occasion day, you could think about 4g/kg. So 4g/68kg= 272g of carbohydrates earlier than your race.
Throughout occasion: 90g/hour (this won’t be particular to your gender or dimension)
After: Each hour, for 4 hours following your race, be sure you get 1-1.2g/kg of carbohydrates.
Your physique NEEDS carbs; this isn’t the time for a low carb eating regimen!
*The above image notes what contributes to a mean 15g of carbohydrate.
Proteins
Now what’s the cope with protein? The RDA recommends 0.8g/kg of protein per day for wholesome people. Nonetheless, research have proven that protein necessities are elevated for athletes. The ADA/ACSM recommends 1.2-2.0g/kg* for endurance athletes corresponding to you!
This vary is important to help metabolic adaptation, restore, reworking, and for protein restoration. The ADA/ACSM suggestions embody most coaching regimes. Nonetheless, necessities can change based mostly on “educated” standing (skilled athletes requiring much less), train depth, carbohydrate availability, and whole vitality consumption.
This requirement might be met by eating regimen alone! Search to distribute top quality protein all through the day and/ or following key coaching classes to the tune of 0.25-0.3g/kg or roughly 15-25g. Analysis exhibits will increase in energy and muscle mass with rapid post-exercise ingestion of protein.
Ex. If you’re 150 lbs, you’re roughly 68 kg (150 lbs divided by 2.2). Whole protein wants all through the day are between 81.6g-136g. Unfold all through the day and following key train bouts. That interprets into = 20.4g to 27.2g unfold over 4 or 5 meals.
It’s essential to eat top quality dietary proteins! In line with the ADA/ ACSM top quality protein sources embody milk-based proteins resulting from their excessive leucine content material and the digestion and absorption kinetics of branched chain amino acids in fluid-based dairy meals. If milk-based merchandise don’t float your boat, beneath is an inventory of different top quality protein sources.
Fat
Fats consumption depends upon train depth, length, and carbohydrate shops/consumption throughout train. Greater carbohydrate and protein consumption usually means decrease fats consumption, which is what you’re going for.
Nonetheless, extreme restriction of fats consumption can be not really helpful. Typically we ought to be on the lookout for fats to make-up 20-35% of whole caloric consumption. To realize correct fats consumption, athletes ought to have a look at roughly 1g/kg each day.
Omega 3 Fatty Acids: Analysis has proven that Omega-3 Fatty Acids, present in each vegetation and fish, are useful to endurance athletes. Omega-3s are present in cell membranes and are essential to immune operate and modulating irritation and restoration.
Endurance athletes that supplemented with Omega-3s skilled decreased muscle soreness, diminished swelling, and in some analysis decreased restoration time. Good animal sources are sardines, salmon, eggs, cod liver oil, tuna. Purpose for between 1000mg-2000mg/ day! One serving of fatty fish each different day will get you to that aim as will the suitable consumption of plant based mostly Omega-3s or a top quality fish oil complement!
To notice: Krill oil has been proven to be particularly efficient at decrease doses than fish oil though extra analysis is required to help these findings.
Take Aways
- Throughout this time of intense coaching, you have to adequately gas your physique. Carbohydrates will make up nearly all of your eating regimen, adopted by protein, after which fats.
