摘要:

In brief:A mail survey of the 50 states and the District of Columbia was conducted to assess the requirements for scholastic preparticipation physical examinations (PPEs). Forty-five replies were received. The results showed that 35 states require a yearly examination and 36 states provide an official state form. Twenty-five states have a medical history questionnaire, but only three states supply a list of contraindications for participation. Several states allow examination by someone other than a physician. Only one of the forms contains a statement of the purpose and/or limitations of the PPE. The requirements and intent of the PPE differ considerably from state to state, indicating that national guidelines for PPEs are needed.

摘要:

In brief:The authors continue their discussion of the physiological responses and adaptations that occur as a result of resistance training. (The discussion began in part 2; part 1 presented the basics of resistance training.) Body composition, neural and cardiovascular adaptations, serum lipid profile, blood pressure, and the endocrine system are covered in this article. The conclusion is that conventional weight training brings about little change in endurance capabilities, but that high-volume, low-load training enhances endurance capabilities and may cause serum lipid profile changes that reduce cardiovascular risk.

摘要:

In brief:Specific diagnosis of an athletic injury to the knee can be difficult if based on history and clinical examination alone. In some cases, arthrography has been used to aid in diagnosis; however, the arthrogram—though accurate—has several disadvantages, including the need for injection of contrast material and exposure of the patient to ionizing radiation. A noninvasive and highly accurate alternative for assessing selected knee injuries is magnetic resonance imaging (MRI). The authors briefly review the theory behind MRI, the history of its development, and its specialized terminology; they describe the procedure, the types of pathologic conditions MRI can demonstrate, and its clinical applications in knee injuries.

摘要:

In brief:Exercise-related sudden death is a clinical syndrome that is well known both to the general public and to the medical community. Autopsy studies of victims have identified multiple structural cardiovascular diseases underlying sudden death in young athletes (aged 30 years and younger). These diseases include myocardial, coronary arterial, aortic, valvular, and cardiac conduction system disorders. In athletes over 30 years of age, the underlying cause is almost invariably severe coronary artery disease. The author discusses these diseases, along with apparent mechanisms of sudden death, clinical points, risks of exercise stress testing, and cardiac rehabilitation, as a basis for attempts to prevent these tragic events.

摘要:

In brief:From 1982 to 1986, Quebec ophthalmologists reported 869 sports-related eye injuries. Hyphema was the most common injury, with a frequency of 33%. Most injuries occurred in ice hockey, followed by racket sports (32% and 28%, respectively); most of the injured players were not wearing eye protection. The authors suggest that wearing eye protection should be mandatory in some sports and encouraged in many others.

摘要:

In brief:The validity of 13 commercially available heart rate (HR) monitors was assessed by comparing the monitored values with simultaneous ECG readings. Stability, as well as validity, was measured using several ergometric devices, and functionality was evaluated by analyzing the practical aspects of each device. Results indicate excellent correlations between readings obtained by ECG and HR monitors using conventional chest electrodes to measure electrical activity of the heart. Most of the monitors using other types of electrodes or using an earlobe photocell to measure opacity of blood flow were inadequate. The authors point out functional differences in the monitors to help potential users choose the best one to fit their needs.
