In briefApproximately 350 female runners in the 1980 Boston Marathon and the Bonne Bell 10-km race answered a questionnaire about running and menstrual history. Most of the women (69.4%) continued to menstruate regularly, 19.3% menstruated at irregular or infrequent intervals, and 3.4% had not menstruated during the previous year. Although there was a statistically significant trend toward fewer menstrual periods in runners with low body weight and high training mileage, less than one fourth of the women had both low weight and high mileage. The authors suggest that physicians seek explanations besides running when evaluating female runners with menstrual irregularity.

摘要:

In briefMany athletes experience sleep disturbances at some time during their careers. Most often these disruptions are due to the stresses of competition or constant travel. This article discusses the protective nature of sleep and its two phases: rapid eye movement (REM) and non-REM. Since sleep loss affects both fine and gross motor activity, the author suggests practical strategies to help athletes get the sleep they need to train and compete and argues that drug therapy is not a solution.

摘要:

In briefThe authors compiled data from 20 National Collegiate Athletic Association lacrosse teams to study the relationship between injuries, protective equipment, and game rules. Athletic trainers for each team kept track of Injuries as they occurred. The 586 players sustained 306 injuries for an injury rate of 52.2%. Half the injuries occurred in the lower extremities, which have no protective equipment. The trunk and arms received 39.8% of the injuries, and the head and face received 9.8%, even though the players are required to wear helmets and face masks. Fewer than 10% of the athletes wore mouth guards. The authors concluded that lacrosse equipment and rules need further study.

摘要:

In briefPhysical activity patterns of 59 children were determined by recording heart rates before and during an exercise intervention program for coronary heart disease risk. Twenty-six children engaged in 25-minute aerobic activity sessions four days a week for eight months; the control group took regular physical education classes. Baseline data revealed that both groups had similar activity patterns, that the children seldom attained a heart rate greater than 160 beats min-1, and that the boys expended significantly more energy per day than the girls. The activity patterns of children in the experimental group improved significantly.

摘要:

Most physicians view annual exams for high school athletes as a wasteful repetition of what can be a valuable screening effort. But high schools are clinging to the‘annual’as an injury liability crutch.

It makes sense to reduce dietary fat and increase exercise, but scientists can't prove that it reverses atherosclerosis.

Richard Dominguez may have achieved some recent notoriety for his stance on static stretching, but that is a small part of his overall involvement in sports medicine.
