EAT TO TRAIN AND RACE ARTICLES

The Triathlete's Kitchen?
"Athletes can stock the kitchen with high-carbohydrate, low-fat foods to eat healthier and save time and money. However, these grocery staples must be individualized to the athlete's preferences and lifestyle or the food will go to waste..." more

Low Carbohydrate Diets
"The shared theme of many popular weight-loss books (Dr. Atkins' New Diet Revolution, Protein Power, Carbohydrate Addict's Lifespan Program, Sugar Busters, and Enter the Zone) is that carbohydrates cause obesity..." more

Carbohydrate Recommendations for Training
"The relationship between muscle glycogen depletion and exhaustion is strongest at moderate training intensities (65% to 85% of VO2max). Low blood glucose, and muscle and/or liver glycogen concentrations can contribute to fatigue during other types of exercise..." more

The Glyemic Index in Sport
"The glycemic index (GI) provides a way to rank carbohydrate-rich foods according to the blood glucose response following their intake. The GI is calculated by measuring the incremental area under the blood glucose curve following ingestion of a test food (glucose or white bread) providing 50 g of carbohydrate, compared with the area under the blood glucose curve following an equal carbohydrate intake from the reference food..." more

Fluid Replacement for Athletes
"Consuming fluids at regular intervals during exercise is vital for safeguarding health and for optimizing athletic performance. Sweat losses constituting as little as 2% of body weight can start to impair performance and temperature regulation..." more

Tips from the Fuel Coach
"It's a common question: How much – and how oftenshould athletes eat in order to sustain a consistent blood glucose level for training throughout the day? What is an appropriate meal frequency and meal size--and what should go into those meals?..." more

Fast to Burn Fat?
"If I want to increase my body's fat burning ability, should I skip breakfast and drink only water on workouts? Ah, the "I burn more fat by not eating" myth. The short answer is no, exercising while fasting does not increase fat metabolism..." more

Eating Out Survival Guide

"Finding a healthy meal within your calorie and fat budget while on-the-go or on-the-road can be a challenge. But, by following a few guidelines for choosing fast foods, eating at restaurants, and ordering from menus, you can have healthier meals away from home..." more

Nutrition and Protein Synthesis
"Athletes in strength and power sports constantly seek nutritional strategies to enhance the effect of resistance training on muscle protein synthesis. Skeletal muscle growth is possible only when muscle protein synthesis exceeds muscle protein breakdown..." more

Recovery Nutrition
"The restoration of muscle and liver glycogen stores is important for recovery following strenuous training. An adequate intake of carbohydrate and energy will optimize muscle glycogen storage during consecutive days of hard workouts..." more

Coping with Holiday Feasting
"Department store lines, credit card bills, and your waistline. These things increase during the holiday season. Unfortunately, there's not much you can do about the first two. But the third is well within your control..." more

Fat Loading Revisited
"Adaptation to a high fat diet or “fat loading” is one strategy utilized by endurance athletes to promote fat oxidation, slow the rate of carbohydrate utilization, and enhance performance..." more

Antioxidants for Health and Performance
"Many people take antioxidant supplements such as vitamins C, E, and beta-carotene (which the body converts to vitamin A) to protect against heart disease, cancer, and other chronic diseases associated with aging. Some active people and athletes also use antioxidants to reduce the amount of muscle damage and soreness caused by heavy exercise..." more

The Glycerol Controversy
"In 1997, the United States Olympic Committee announced the addition of glycerol to the banned substances list. The USOC ban is based on glycerol being classified as a diuretic, since in high doses (1 to 2 g per kg) it can be used to 'make weight'..." more

Sports Bars and Gels
"In today's fast-food society, many runners seek convenient high carbohydrate snacks that provide energy quickly and are easily carried. It's not surprising that sports bars and carbohydrate gels are often considered 'power foods'..." more

Pre-Exercise Nutrition
"Triathletes often train or compete in the morning without eating. This overnight fast lowers your liver glycogen stores (the source of blood glucose) and can cause fatigue during exercise..." more
