Hitting the Wall

As athletes, I am sure you have all heard the expression "hitting the wall." That feeling when you have nothing left to give during your workout or competition. Do you really know what is happening inside your body?

When an athlete "hits the wall" it means that he or she has exhausted all of their stored carbohydrate (glycogen) in their body, which leaves the body running on empty. The body uses both fat and carbohydrate as fuel sources when exercising, but during high-intensity activities such as running or cycling, your body relies on carbohydrate for the main source of energy. Your body will not exhaust all of your fat stores during activity, but it can deplete your stores of carbohydrate.

This condition can by avoided by beginning your activity well-nourished with your carbohydrate stores full. During long longs or rides, be sure to take in carbohydrate through whole foods or sports drinks. The recommended amount is about 30-60 grams of carbohydrate per hour of activity.

Homemade Sports Drink

Looking to save a little money? It's possible to make your own sports drink at home. Sports drinks are made to provide fluid, carbohydrate, and electrolytes during long duration, high-intensity exercise - but you don't have to buy it in the store! Here is a recipe for a sports drink that you can make at home. The recipe is from Nancy Clark, MS, RD, CSSD - a well respected sports dietitian in the Boston area. Enjoy!

1/4 cup sugar
1/4 teaspoon salt
1/4 cup hot water
1/4 cup orange juice (not concentrate) plus 2 tablespoons lemon juice
3 1/2 cups cold water

1. In the bottom of a pitcher, dissolve the sugar and salt in the hot water.
2. Add the juice and the remaining water; chill.

Summer Sweat

It's been a hot week here in Sioux Falls. So in keeping with that theme, I thought I would mention a few quick notes about sweat and the factors that affect it. Some people are heavy sweaters and some are not. Why is that?

Genetics. That plays a huge part in how much you sweat and cannot be changed. But there are other factors that you need to consider. How hard are you working (intensity level) during your exercise? What is the weather like? Are you acclimatized to the conditions?

Hot and humid environments (summer!) will cause an increase in sweat rate. If you are doing a lot of outdoor activities, be sure you are paying close attention to your hydration needs. The recommended water intake for men is 3 L per day and 2 L per day for women. However, that does not include any sweat loss from extra activity. If you are sweating a lot that day, you need to add to that amount. 

Go out there and enjoy summer activities while you can! Hiking, running, biking, or whatever you choose. Be sure to pack that water bottle with you!

Sheep's hearts in plum sauce

This is a nice dish. I imagine the sauce would be quite good with other dark, gamy meats, like wild duck, wild goose or possibly wild boar.

To serve 6:
6 lamb's or sheep's hearts
100 g flour
butter for frying
salt and pepper
6 well ripe plums (it doesn't say which kind, but the photo with the recipe shows red plums with yellow flesh - BTW, don't expect to see any such thing when the dish is
