Nutritional Effects on Performance Part 1

Nutritional Effects on Performance

Whether you are performing in a sports competition, on the road in a car, at your desk at work or at home with your family, what you consume makes a difference. Food and drink will either help your performance or hinder it.

 

HYPOGLYCEMIA SIGNS & SYMPTOMS: Symptoms associated with hypoglycemia include, fatigue, foggy thinking, shakiness, forgetfulness, drowsiness, exhaustion, depression, crying spells, indecisiveness, incoordination, dizziness, blurred vision, unprovoked anxiety, numb-like feeling in hands, arms, face, tingling lips, nervousness, irritability, stomachache or nausea, headache, sweating (cool), rapid heartbeat, confusion or disorientation, weakness, hunger. In more advanced hypoglycemia also includes slurred speech, tremors, and loss of consciousness. Most of this occurs if you miss or delay a meal. Note that these symptoms are commonly very slow to set in, you may only experience one of the symptoms, and because of this, it may go by unnoticed.

Effects on Performance: The brain is highly dependent upon glucose for oxidative metabolism and function. Hypoglycemia impairs simple brain functions and is associated with task-specific localized reductions in brain activation. For a task with greater cognitive load, the brain has to recruit other regions in an attempt to limit dysfunction. However, unlike alcohol effects, you may be somewhat aware of the increased effort required to perform more complex tasks. Reaction time slows, multitasking diminishes and short-term memory deteriorates. The visual pathways in the brain get affected and spatial perception is altered as well as visual associative function. Simple visual stimulus during tests showed decreased activation of response in the brain. Deficits in all relevant areas of cognitive function will occur during hypoglycemia.

Causes:

Missed or inconsistent meals. Or meals made up of coffee, candy bar or pastry. Diets high in refined carbohydrates such as white rice, potatoes, bread, cereals, grains, beans, legumes and most of your “white” foods along with low protein. Need especially protein, but also fiber and fats to stabilize it. Other Causes: Ethanol in alcohol and certain drugs.

Solution:

The best solution is proper meal planning. It is suggested that your performance can be affected by both the timing and type of food intake. Keep a protein bar, trail mix, and/or cut up fruit as a back up in your car or purse.

NOT a solution:

Aspartame.

Signs & Symptoms:

Memory loss, headaches, migraines, blurred vision, blindness, seizures, dizziness, hearing loss, muscle spasms, nausea, heart palpitations, numbness, slurred speech, insomnia, fatigue, severe rashes, anxiety attacks, breathing difficulty, loss of taste and ringing in the ears, pituitary tumors. It is a dangerous chemical and has no place in your diet!
