摘要:

In brief: The heart rates of 15 racquetball players were monitored during singles and doubles competition. During a one-hour singles match subjects attained an average of 83% of their maximum heart rate reserve (MHRR) and played above 60% of their MHRR for 56 continuous minutes. During doubles competition, the subjects averaged 67% of their MHRR and played above 60% of their MHRR for 29 continuous minutes. The total active playing time above 60% MHRR was 59 minutes in singles and 45 minutes in doubles. Doubles is less strenuous than singles competition in racquetball, but both forms of exercise meet the criteria for exercise intensity established by the American College of Sports Medicine for developing and maintaining cardiorespiratory fitness.

摘要:

In brief: The body composition of 49 female intercollegiate basketball players was used to derive a sport-specific equation and to assess the applicability of the Sloan et al (population-specific) and Jackson et al (generalized) equations for use with this sample. The sport-specific equation yielded an adjusted multiple regression of.71 and a standard error of the estimate (SEE) of.0077. A comparative analysis indicated that mean body density was significantly underestimated by 0.0112 gmml−1using the Sloan and by 0.0126 gmml−1using the Jackson equations. The SEEs for the Sloan (.0073 gmml−1) and Jackson (.0085 gm ml−1) equations were low; however, each equation produced a large total error (.014 and.016 gmml−1).

摘要:

In brief: To better delineate the quality of medical care of intercollegiate football teams, a questionnaire was mailed to all colleges in the United States that participated in intercollegiate football programs. Out of 686 questionnaires, 449 (65.5%) were returned. The questionnaire was designed to solicit in-depth information about the involvement of physicians and trainers in the health care of the football players. The team members of the larger, more prestigious schools generally received excellent care. However, the medical care for most of the remainder of the schools was considered inadequate.

摘要:

Highly publicized accounts of drug abuse among athletes have posed a threat to‘the integrity of the game.’But officials at all levels of sports think that the best defense against drugs is a good offense: a drug testing program.

摘要:

Are television exercise shows leading viewers to fitness or just profiting from intense consumer interest? And just how responsible is television for dispensing safe and accurate information?

摘要:

Progress in making sports medicine a specialty has been spotty because the filed lacks definition and full-tome physicians.
