Contagious Infections in Competitive Sports

Many athletes believe that physical training enhances immunity and helps prevent upper respiratory tract infection (URTI) like the common cold or \"flu\" (influenza). They also believe that physical activity and fitness help them overcome any minor infections they do get. On the other hand, based largely on anecdotes and on popularization of a link between physical or psychological stress and \"impaired immunity,\" the athletic community in general seems persuaded that intensive training, exhaustive exercise, or competition predisposes athletes to infections.

Children's Responses to Exercise in Cold Climates: Health Implications

Exercise and climatic heat both induce heat stress. Their synergistic effect, when excessive, may impair physical and cognitive performance, cause hyperthermia, and be detrimental to a child's well-being and health. In contrast, when the body is exposed to a cold environment, exercise-induced thermogenesis will help to prevent excessive body cooling. Therefore, hypothermia (core body temperature of 35o C or less) is more likely to occur during rest than during exercise.

Children's Responses to Exercise in Hot Climates: Implications for Performance and Health

Children's physiologic responses to exercise are generally similar to those of adults, but there are several ageand maturation-related differences in their responses. For example, children respond to the combined stresses of exercise and climatic heat differently than do adults (Table 1).\r\n\r\n\r\n

The Older Athlete: Exercise in Hot Environments

Adequate fluid intake before, during and after exercise in hot conditions should be emphasized for older exercisers. Aerobic fitness, acclimation and hydration status are important factors to consider when exercising in the heat.

Exercise Effects on Children's Health

Participating in sports and/or an exercise program can be important for a child's development and health status. While too much exercise may pose health risks, more children could benefit by increasing their physical activity level.
