The Juvenile Obesity Epidemic: Strike Back with Physical Activity

The last three decades have seen a dramatic surge in prevalence of children and adolescent obesity in many developed and underdeveloped countries. Even though the causes of this epidemic are not clear, the reduction in time spent in physical activity and the increase in sedentary pursuits such as TV viewing and computer games are likely contributing factors.

\r\n\r\nProper management of juvenile obesity should include nutritional changes, behavior modification and a physically active lifestyle.

Hyponatremia in Athletes

Hyponatremia is a rare disorder that results from a combination of abnormal water retention and/or sodium loss. Water retention can occur from excessive water retention by the kidneys or from drinking too much water. A combination of excessive drinking and salt loss reduces plasma sodium concentration. This can prompt a cascade of events that might result in a rapid and dangerous swelling of the brain that could cause seizures, coma, and even death.

The risk of hyponatremia can be reduced by making certain that fluid intake does not exceed sweat loss and by ingesting sodium containing beverages or foods to help replace the sodium lost in sweat.

Heat Stroke in Sports: Causes, Prevention and Treatment

Heat stroke is typically caused by a combination of environmental, physical, and behavioral factors. Dr. Eichner summarizes the causes that contribute to this illness, its treatment, and also the preventive measures to protect the athletes. Heat stroke is very serious. Preventing this illness involves acclimation, hydration, pacing, cooling and vigilance. It is important to recognize its early symptoms and to provide fast and effective treatment. Cooling the athlete is the first priority before transporting to the emergency room. This can save lives.

Exercise, Antioxidants, and Cardioprotection

Exercise, Antioxidants and Cardioprotection Cardiovascular disease is the major cause of death in the United States. Regular exercise and dietary intake of adequate nutritional antioxidants are lifestyle factors that can provide protection against this threat. Dr. Scott Powers's review summarizes our current knowledge regarding the cardioprotective effects of both exercise and dietary antioxidants.

Optimizing Bone Health: Impact of Nutrition, Exercise, and Hormones

Osteoporosis is a preventable condition, but the fact is that too few Americans (men and women) ingest enough calcium or exercise enough to\r\nprevent it. Everyone should try to maximize peak bone mass by age 30 and attempt to slow the rate of loss afterwards. The latest research on osteoporosis, exercise to maximize peak bone mass, and the role of calcium intake are issues addressed in this article by Dr. Susan Bloomfield

Carbohydrates, Hormones, and Endurance Performance

Strenuous prolonged exercise causes a decrease in blood glucose and a corresponding increase in concentrations of the glucoregulatory hormones. At the same time blood insulin levels fall. Carbohydrate ingestion during endurance exercise blunts these hormonal alterations and can help spare muscle glycogen, maintain blood glucose and therby delaying fatigue.

Dietary Carbohydrate & Performance of Brief, Intense Exercise

How beneficial is dietary carbohydrate when your sport consists of short repeated bursts of high power? Studies examining resistance exercise, single and repeated sprints, and the role of carbohydrate as a fuel are contained in this latest publication. The supplement includes a formula to calculate your personal carbohydrate needs, instructions for analyzing your own diet, and a table illustrating the carbohydrate content of common foods.

Screening For Risk Of Cardiac Death In Young Athletes

The sudden cardiac-related death of an athlete during a sports event is a particularly poignant tragedy. Participation in sports--a wholesome pursuit that provides important physical and psychosocial benefits--is not expected to place young, apparently healthy competitors at risk for cardiovascular collapse. When sudden deaths occur in elite-level athletes who have national media exposure, the concerns become magnified. How safe is sports play? What causes these tragic events? How can they be prevented?

Exercise, Macronutrient Balance, and Body Weight Regulation

The accumulation of excess body fat appears to be fundamentally a problem resulting from inadequate fat oxidation relative to intake. An increase in body fat mass incrreases the concentration of free fatty acids in the blood, and this increased availability of lipid fuel is associated with increased fat oxidation. The increase in fat utilization that accompanies obesity helps re-establish a new equilibrium between fat intake and fat oxidation that serves to stabilize body weight, albeit at the cost of obesity. Because exercise can increase total daily energy expenditure and fat oxidation, chronic exercise can help prevent expansion of the adipose tissue mass, allowing the physically active individual to achieve fat balance at a lower body fat mass.

Nutrition Needs for Team Sport

There is a common belief that there are sport-specific diets. The truth is that there are only people-specific diets. The first nutritional requirement for athletes and their sports fans is a well-balanced diet that contains a wide range of foods and covers daily energy expenditure. As for the composition of this diet, health professionals recommend that it should be high in carbohydrate and low in fat (FAO/WHO, 1998). Ensuring that athletes follow these guidelines is the first step in the successful nutritional support for sports participation.

Immunity in Athletes: Current Issues

Publications on the topic of exercise immunology date from late in the 19th century, but it was not until the mid-1980s that a significant number of investigators worldwide devoted their resources to this area of research endeavor. From 1900 to 1997, just under 900 papers on exercise immunology were published, with 75% of these appearing in the 1990s. \r\n\r\n

Anti-Inflamatory Drugs, Kidney Function, and Exercise

Nonsteroidal anti-inflammatory drugs (NSAIDs) are used by competitive athletes and recreational exercisers because of their analgesic (pain reduction) and anti-inflammatory benefits. A list of common NSAIDs and other analgesics available over-the-counter (OTC) is presented in Table 1 (Physicians' Desk Reference, 1997).

Spinal Cord Injury and Exercise in the Heat

Opportunities to compete in the Para-Olympics, advances in medical treatment and therapies for functional recovery of the disabled, and the recognition that physical activity is beneficial for the health of everyone, abled or disabled, have contributed to increased participation of disabled individuals in regular physical exercise. Like able-bodied athletes, disabled athletes face limitations to performance-fatigue, nutrition and fluid needs, and the possibility of heat exhaustion. In this report, we will discuss thermoregulation and cardiovascular function in the disabled athlete. We will make several recommendations to reduce the chance of heat illness and to delay fatigue in the disabled athlete.\r\n

Carbohydrates, Branched-Chain Amino Acids and Endurance: The Central Fatigue Hypothesis

The central fatigue hypothesis suggests that increased brain serotonin (5-HT) can cause a deterioration in sport and exercise performance. Whether branched-chain amino acid supplementation can effect performance remains uncertain.

The Role of Red Meat in an Athlete's Diet
