In briefThe authors provide guidelines for returning children with Perthes disease to sporting activities. They suggest maintenance of hip motion and containment of the femoral head in the acetabulum until the extent of the femoral epiphyseal necrosis can be determined. Swimming and adaptive physical therapy help regain the motion and strengthen the hip abductor muscles. Abduction brace therapy is continued in patients with a risk of femoral head deformity until reossification of the necrotic femoral head begins. Surgical containment, as an alternative to brace therapy, is recommended when an orthosis is not socially tolerated. Once reossification of the femoral head occurs, the patient may begin full activity, but osteochondritis dissecans with an osteocartilaginous loose body should be considered if catching or locking of the hip joint occurs.

摘要:

In briefSleep disturbances at high altitude may be caused by simple physical discomforts but may also be a symptom of acute mountain sickness (AMS). Nevertheless, restful sleep is necessary to perform work optimally the next day. Acclimatization is the best way to prevent AMS, but if drugs are used to promote sleep, acetazolamide is the drug of choice. During tests on Mt. Logan, all subjects said they slept better and had less morning headache after using acetazolamide. The amount of Cheyne-Stokes breathing was reduced, arterial oxygen saturation was improved, and there was no profound hypoxemia. Traditional sedatives are often used but should be used with caution because they can worsen sleep hypoxia, impair judgment and coordination the next day, and turn a climb into a life-threatening situation.

摘要:

In briefTo evaluate the incidence of major cardiovascular complications (CVCs) during recreational activity the authors conducted a five-year retrospective survey of fatal and nonfatal CVCs that occurred in community recreation centers during or immediately after exercise. Forty-eight facilities reported 30 nonfatal and 38 fatal CVCs. Although most (57%) occurred during court games and jogging, the data are insufficient to infer any increased relative risk during these activities. There was one nonfatal and one fatal event every 1,124,200 and 887,526 hours of participation, respectively. These data suggest a small acute risk of CVC in the general public during recreational activity.

摘要:

In briefA large survey of martial arts athletes was conducted, and 24, 112 injuries were identified. The areas most commonly injured were the thighs, legs, and digits. Contusions, sprains, and strains were the most common types of injuries. Most injuries occurred in less experienced people, and the number of injuries decreased as expertise and training increased. Only 47 serious injuries were recorded, a rate of 1 in 500 injuries. Most serious injuries, especially head injuries, occurred while sparring and in tournaments. Less than half the injuries that occur during tournaments are brought to the attending physician. This may be because the injuries were minor or because of tournament psychology.

摘要:

In briefSports nutritionists generally think an athlete's increased mineral requirements can be satisfied by a greater but well-balanced caloric intake. This study supports that concept, demonstrating that 12 male runners who consumed an unrestricted, isocaloric diet maintained normal plasma mineral levels without using mineral supplements during a 500-km (312-mile) road race. None of the nine minerals tested (calcium, phosphorus, sodium, potassium, chloride, magnesium, iron, copper, and zinc) showed tendencies to become persistently reduced over the 20-day period.

摘要:

In briefThe sports medicine unit at Wake Forest University organized medical and paramedical personnel to care for the medical needs of 1,800 athletes competing in the 1981 Junior Olympic Games. Based on these experiences, the unit offers recommendations for sports medicine care at future large-scale sports competitions of an intensive short duration, including physician coverage at all competitive wrestling, judo, and boxing events; separation of throwing and running events in track-and-field competition; and communication among H all medical, ambulance, and security personnel. In addition, at least 20 certified athletic trainers are needed for events of this size.

摘要:

In briefA profile of four wheelchair marathon racers (WMRs) is presented including an athletic history, dietary habits, maximal oxygen uptake, and average race pace oxygen uptake (Vo2) values. These values were compared with those of able-bodied marathon runners matched for age and race time. The WMRs had lower Vo2max, maximal heart rates, and higher respiratory exchange ratios, and they used a higher percentage of their Vo2max and maximal heart rate at race pace. The authors suggest that a high degree of training is required to perform the grueling marathon.

摘要:

In briefECG monitoring is generally recommended for patients in cardiac rehabilitation, but the optimal amount of monitoring is uncertain. This article reviews several questions regarding this issue. The authors conclude that monitoring during exercise testing is necessary to determine an appropriate exercise prescription for all cardiac patients, but additional monitoring is not indicated during upper extremity as opposed to lower extremity exercise. They also believe that all patients entering exercise programs soon after hospital discharge should be monitored for at least seven weeks, and preferably 12. Periodic monitoring is useful for recognizing potential problems and evaluating long-term medication effectiveness.
