A Forum For Our ReadersSportsmedicine Forum is intended to provide a sounding board for our readers. Perhaps you have a special way to treat a common medical problem, or you may want to air your views on a controversial topic. You may object to an article that we have published, or you may want to support one. You may have a new trend to report, identified through an interesting case or a series of patients. Whatever your ideas, we invite you to send them to us. Illustrative figures are welcomed.

摘要:

In brief:This article summarizes the psychological research on youth sports and offers suggestions for advising young athletes, parents, and sports organizations. Specific topics include the psychological benefits and dangers of youth sports, competitive stress, and the optimum age for competition and sports specialization.

摘要:

A group of experts met to discuss a case from the University of California, San Diego, School of Medicine. This case conference is part of a series featuring a variety of sports medicine topics.

摘要:

In brief:A 16-year-old high school football player and wrestler began experiencing groin and pubic pain, and a popping sensation with abduction movements, after sustaining an abduction injury to his lower extremities. Stress roentgenographs revealed instability of the pubic symphysis; there was no evidence of fracture or gross instability of the sacroiliac joints or the posterior sacrum. The patient was treated conservatively for one year, with an initial period of limited weight-bearing and rest followed by progressive stretching and strengthening exercises and a gradual return to full sports activity.

摘要:

In brief:Although preparticipation examinations are required for all Special Olympics athletes, information in the medical literature is limited concerning the difficulty in screening this group and in clearing them for competition. The results of 176 preparticipation exams are included in this report. The most striking finding was deficient visual acuity in half the athletes tested. Ruling out atlantoaxial subluxation in the athletes with Down's syndrome presented a special problem. The author suggests that the most effective method for screening Special Olympics athletes is a single-station/single-examiner format performed during school hours. She suggests improvements in the design of the consent forms to make physicians and parents aware of the special needs of these athletes.

摘要:

In brief:Part 1 of this series of articles discussed basic concepts of resistance training. This article addresses selected physiological responses and adaptations to resistance training, including changes in muscle size, muscle enzymes, maximal oxygen consumption, connective tissue, and bone mineral content. Physiological responses and adaptations have been more thoroughly studied in endurance athletes than for those in resistance training programs. However, sufficient research has been conducted to discuss some of the specific responses and adaptations, which the authors do in this paper.

摘要:

In brief:Twenty-five exercisers suffering from shin soreness were interviewed, examined, and monitored to identify factors associated with this injury. Twenty-five uninjured persons who matched the injured subjects in age, sex, and activities served as controls. Injured subjects had a greater range of subtalar joint motion and increased ankle dorsiflexion, reported a significantly lower calcium intake, had raised their training intensity before injury, and were using worn or poorly made shoes when injured. Factors not associated with injury included number of months subjects had participated in weight-bearing exercise, exercise surface, amount of stretching, height-weight ratio, and menstrual status. This study is the first to indicate a possible relationship between nutrition and shin soreness.

摘要:

In brief:Eleven obese adults (three men, eight women) performed three 30-minute walking sessions at 3.4 mph: normal walking, walking with increased arm movement, and walking with increased arm movement while holding hand weights. The purpose was to assess the additional energy expenditure induced by carrying hand weights. Walking with hand weights resulted in increased heart rate (127 vs 120 beats·min−1), increased VO2(1.168 vs 1.086 L·min−1), and greater energy expenditure (171.5 vs 159.7 kcal) compared with normal walking. Fat use and recovery energy expenditures were similar in all exercise conditions. Increased arm movement while walking without weights resulted in no significant increases over normal walking. These results indicate that using hand weights increases the energy demands of walking, but only to a small degree.

摘要:

In brief:For this study of the acute effects of stretching techniques on arterial blood pressure (ABP), 60 men were assigned to one of three treatment groups, each consisting of one modified proprioceptive neuromuscular facilitation (PNF) technique: hold-relax, contract-relax, and slow-reversal-hold-relax (SRHR). Flexibility and ABP data were collected from both baseline (passive stretch) and treatment measurements for each group. AH three treatments were more effective than the baseline stretch for increasing flexibility; the SRHR treatment provided the greatest flexibility. Increases in treatment ABPs were nonsignificant, compared with baseline measures. The authors conclude that the potential benefits of PNF may outweigh the risks of elevated ABP.

摘要:

The first women's world weight-lifting competition—held last fall in Daytona Beach, Florida—is evidence that the sport is growing and building its case for Olympic medal status. But little is known about the medical aspects of weight lifting for women.
