Generalization of social anxiety to sporting and athletic situations: gender, sports involvement, and parental pressure.

Although researchers have documented that social anxiety may occur in a wide range of interpersonal and performance situations, little attention has been paid to the potential influence of social anxiety on participation in athletics or physical activity. The performance demands of sport and potential social evaluative nature of exercise make it likely that social anxiety would generalize to these situations. Given the physical and psychological benefits of engaging in regular physical activity, avoidance of such activities by socially anxious individuals may have profound health consequences. One-hundred and eighty undergraduate university students completed a battery of standardized social anxiety measures, and a series of 5-point Likert-type questions examining fear and avoidance of sporting and athletic situations. Results indicated that social anxiety and fear of negative evaluation were generally related to social-evaluative fears in sporting or athletic situations, particularly for women. Furthermore, social anxiety was positively correlated with avoidance of individual sporting activities, but not with avoidance of team activities. Further analyses revealed social anxiety did not differ by competition level. However, for men, familial pressure to play sports during high school was associated with higher fear of negative evaluation. Implications for the assessment and treatment of social anxiety disorder are discussed.

Self-perceived health among sports participants and non-sports participants.

This paper examines and compares the self-perceived health (SPH) of a sample of sports participants (n = 1385) and a matched sample of non-participants (n = 292). Ratings of health were generally found to be favourable among both samples, but a non-parametric analysis of their distributions revealed that the SPH of sports participants was significantly (P less than 0.0001) better than that of the non-participants. SPH improved with age among both samples, but above the age of 34, the non-participants' perceived health ceased to be inferior to that of participants. Controlling for age and gender revealed no difference in SPH above 24 years among males and 34 years among females. SPH was related to a variety of additional health-related factors. Multiple regression analysis was used to identify the predictors of SPH for both samples, and highlighted marked differences between them in the type and number of contributory factors. It is suggested that participation in active sports may enhance health awareness, especially among the young, and that future studies of this kind among sports populations should take account of the levels of commitment (frequency, duration and intensity) to sport.

Hypertrophic cardiomyopathy--sports-related aspects of diagnosis, therapy, and sports eligibility.

Hypertrophic cardiomyopathy (HCM) is one of the primary causes of sudden cardiac death in athletes < 35 years of age. The highest risk of sudden cardiac death is associated with syncope, early age, extreme ventricular hypertrophy, ventricular tachycardia, and a family history of sudden death. The relative risk in competitive sports is unknown. Usually, sports eligibility is rejected. However, some athletes with HCM tolerate extreme athletic lifestyles without complications. Sports-related aspects of diagnosis, therapy, and sports eligibility are presented, and discussed. Two case reports are presented: a 20-year-old professional soccer player and a 66-year-old long-distance runner. Athletes with HCM should not participate in most competitive sports with the possible exception of those of low dynamic and low static intensity. Participation in low to moderate athletic activities may be allowed in selected patients without risk factors and > 35 years of age.

Characteristics of sports-related dermatoses for different types of sports: a cross-sectional study.

Skin lesions are common in athletes. Athletic activities may lead to new skin lesions or aggravate existing ones. We aimed to determine the effects of sport type and participation length on the occurrence of sports-related dermatoses and to identify the localization characteristics of these lesions. A total of 121 licensed athletes (42 swimmers, 23 handball players, 33 soccer players and 23 wrestlers) and 121 sedentary controls were included in the study. A consultant dermatologist examined all subjects. Lesion types, duration, and localization characteristics were noted. The lesions were categorized as viral, bacterial, traumatic, and non-traumatic. Traumatic lesions were frequently seen in soccer players and wrestlers; fungal infections were more commonly seen in swimmers and in soccer players. Lesion types and localizations varied by sport type. There were no significant relationships between sport type and the incidence of viral and bacterial lesions. The results suggest that athletic activity seems to be a predisposing factor, especially for fungal infections and acute or chronic traumatic lesions. Thus, regular dermatological screening of athletes is critical for rapid identification and treatment of dermatoses disrupting sport performance.

Assessing agreement between measurements recorded on a ratio scale in sports medicine and sports science.

OBJECTIVE: The consensus of opinion suggests that when assessing measurement agreement, the most appropriate statistic to report is the "95% limits of agreement". The precise form that this interval takes depends on whether a positive relation exists between the differences in measurement methods (errors) and the size of the measurements--that is, heteroscedastic errors. If a positive and significant relation exists, the recommended procedure is to report "the ratio limits of agreement" using log transformed measurements. This study assessed the prevalence of heteroscedastic errors when investigating measurement agreement of variables recorded on a ratio scale in sports medicine and sports science. METHODS: Measurement agreement (or repeatability) was assessed in 13 studies (providing 23 examples) conducted in the Centre for Sport and Exercise Sciences at Liverpool John Moores University over the past five years. RESULTS: The correlation between the absolute differences and the mean was positive in all 23 examples (median r = 0.37), eight being significant (P < 0.05). In 21 of 23 examples analysed, the correlation was greater than the equivalent correlation using log transformed measurements (median r = 0.01). Based on a simple meta-analysis, the assumption that no relation exists between the measurement differences and the size of measurement must be rejected (P < 0.001). CONCLUSIONS: When assessing measurement agreement of variables recorded on a ratio scale in sports medicine and sports science, this study (23 examples) provides strong evidence that heteroscedastic errors are the norm. If the correlation between the absolute measurement differences and the means is positive (but not necessarily significant) and greater than the equivalent correlation using log transformed measurements, the authors recommend reporting the "ratio limits of agreement".

Sport, age, and sex specific incidence of sports injuries in Western Australia.

OBJECTIVE: To describe the trends in recreational sports injury in Perth, Western Australia. DESIGN: A prospective cohort study of sports injuries during the 1997 winter season (May to September). SETTING: Sample of Australian football, field hockey, basketball, and netball players from the Perth metropolitan area, Western Australia. METHODS: A cohort of sports participants was followed over the five month winter sports season. Before the season, participants completed a baseline questionnaire and during the season were interviewed every four weeks by telephone. RESULTS: Overall, 92% of participants (n = 1391) who completed a baseline questionnaire completed at least one follow up telephone interview. About half (51%) of the cohort sustained one or more injuries during the winter season accounting for a total of 1034 injuries. Most injuries were of moderate (58%, n = 598) or minor (40%, n = 412) severity, with only 3% (n = 24) requiring emergency department treatment or a hospital stay. The injury incidence rate was greatest for football (20.3/1000 hours of participation), similar for field hockey and basketball (15.2/1000 hours and 15.1/1000 hours respectively), and lowest for netball (12.1/1000 hours). The incidence of injury was greatest in the first four weeks of the season, and participants aged between 26 and 30 years had about a 55% greater risk of injury than those aged less than 18 years. CONCLUSIONS: This is one of the first studies to show that recreational sports are safe. Although the likelihood of injury was greatest in the first month of the season, few injuries required admission to hospital or emergency department treatment. A greater emphasis on prevention in the early part of the season should help to reduce the elevated incidence of injury found at this time.

Sport injuries: relations to sex, sport, injured body region.

The present study evaluated the association among sex, sport, and injured body region of sport injuries. The subjects were 329 men and 127 women, ranging in age from 17 to 28 years, attending classes in the departments of Physical Training and Sport of Atatürk University (Erzurum, Erzincan, and Ağri in Turkey). There were no differences between men and women in percentages of injuries. The difference among various sports in the percentages of injured athletes was statistically significant. Running had the lowest percentage of injuries and basketball had the highest percentage. The most frequently injured body regions were the foot and the ankle in basketball, volleyball, soccer, and running, but in wrestling, the knee. These findings suggest that injury rates are associated with the sport rather than sex of player, and the most frequently injured body regions are the lower extremities. Therefore, the muscles of lower extremity should be strengthened to avoid injuries.

[Sports and health-related values orientation and their realization in sports activity in the leisure time of adolescents].

Findings of the questionnaire-based study "Youth and Mass Sports 1987" are presented. Though the value of remaining healthy and efficient is generally recognized, only every second adolescent is actively involved in sports. There is also a gap between sport-related value concepts and own physical activity. Its reduction requires to take into account and promote such complex factors as physical capacity, a sport-favouring climate at home, at school and at work. Preferences for the various forms of leisure sport activities should be acknowledged.

A descriptive epidemiology of sport and recreation injuries in a population-based sample: results from the Alberta Sport and Recreation Injury Survey (ASRIS).

The 1996 Alberta Sport and Recreation Injury Survey is a retrospective study describing the annual incidence of injuries in the province of Alberta resulting from sport and recreational involvement. Data was collected by means of a telephone survey using random digit dialing techniques to obtain a representative sample of Albertans in the winter of 1995-96. The sample produced a total of 3,790 respondents from 1,478 households evenly split between genders, with an age range of 6 to 93 years. The survey asked information regarding medically attended, non-fatal injuries resulting from sport and recreational activities. Findings reveal an annual incidence of sport or recreational injuries of 11%. Among those reporting a sport or recreational injury, the most common types of injuries were a sprained/torn ligament (31%), strained/pulled muscle (19%), and fracture (13%). The most common bodily locations of injuries were the knees (21%) and the ankle (14%).

Sports physicians and the doping crisis in elite sport.

The participation of sports physicians in the "doping" of athletes with banned drugs can be documented as far back as the 1890s. Concern about the ethics and safety of doping elite athletes appeared during the 1920s and 1930s as sport became an increasingly important form of popular culture. While organized medicine has opposed doping as a matter of policy at least since the 1950s, sports physicians have never adequately confronted the conflicts of interest that arise when they choose to work with elite athletes whose first priority is performance rather than with healing in the traditional sense. Confronted with the demands of their athlete-clients, sports physicians have divided into two factions regarding the wisdom and propriety of administering doping drugs to athletes. While most physicians are, in all likelihood, unwilling to violate laws, regulations, and medical standards by doping athletes, a significant minority of doctors has used one or more arguments to justify doping athletes: drugs are necessary to compete effectively; athletes should be free to medicate themselves as they please; drugs do not differ essentially from other performance-enhancing techniques or equipment; and medically supervised doping is safer than self-medication by athletes. Physicians can also rationalize doping as an occupational requirement of some professional athletes. In summary, physicians have played a significant, and largely unacknowledged, role in the doping of many elite athletes over the past 50 years.

[Leisure time and sports. Sports for all ages].

Studies about life-time sport of different groups of population in Switzerland showed that 82% of 1990 apprentices in the town of Zürich and 59% of young peasants were active in sports in their leisure time. On Saturdays, 45% of the inhabitants of Zürich spent any hours with leisure time sport, on Sundays even 70% (including mountaineering). From seniors (80 years old), 63% were active in sports formerly in their life, from men dead before 65 years from the same factory only 44%.

Survey of orthopaedic and sports medicine physicians regarding use of medrol dosepak for sports injuries.

PURPOSE: To study the use of a methylprednisolone taper (Medrol Dosepak; Pfizer, New York, NY) short-term oral corticosteroid treatment modality by sports medicine physicians; included is discussion on indications, perceived efficacy, and complications. METHODS: A survey specific to Medrol Dosepak (MDP) use was mailed to all members of the Arthroscopy Association of North America (AANA) and the American Orthopedic Society for Sports Medicine (AOSSM). Surveys were collected and data were collated and analyzed. RESULTS: Total response rate was 41% (1,290/3,167), US response rate 43% (1,247/2,906), and international response rate 16% (43/261). Prescribing of MDP for sports injuries was significantly associated with average patient age <or=40 years (chi square; P = .001), but it was not associated with years in practice or patients seen per year. It was found that 47% of members (603/1,290) prescribe MDP. Postinjury disease was the most common indication. The most frequent complication was glucose intolerance (37%; 222/603). Of members who prescribe MDP, 8.5% (51/603) reported that they had seen 101 total cases of osteonecrosis, predominantly in the hip. Results revealed that 52% of members (672/1,290) do not prescribe MDP. The most frequent reasons for not prescribing included fear of osteonecrosis (30%; 201/672), fear of complications in general (27%; 183/672), lack of proven efficacy (27%; 180/672), and fear of malpractice (4.5%; 30/672). Of nonprescribing members (171/672), 25% had seen 500 cases of osteonecrosis, most often in the hip. CONCLUSIONS: The responding membership of AANA and AOSSM is evenly split regarding MDP use. Average patient age <or=40 years was associated with a greater likelihood that MDP would be prescribed for sports injuries. Postinjury disease is the most common indication; lack of proven efficacy and osteonecrosis are deterrents to prescription. LEVEL OF EVIDENCE: Level V, expert opinion.

[Central dysregulations as a cause of movement disorders in performance sports? An analysis of movement in sports with reference to functional anatomic and neurophysiologic viewpoints].

Typical orthopaedic findings and typical disturbances of movement in sports point to central dysregulation in motor disturbances in competitive sports compared with the ideal models set up under biomechanical aspects and from the viewpoint of sports practice. Neurophysiological data collected so far confirm this view. The central influence on movement is manifested by a change in peripheral proprioceptive properties, i.e. by a change in the pre-innervation of the musculature. If the musculature is subjected to high strain as in sports aiming at high performance levels, such changes produce an extremely high stretch tone in the phase of dynamic-eccentric muscular contraction resulting in functional reversal of two-joint muscles such as the M.rectus femoris and the M.gastrocnemius. This procedure is manifested in the region of system-immanent weak spots of the positional and locomotor system and, in the pelvic girdle region by tipping of the pelvis in ventral direction, with consecutive evasive shifts of the vertebral column and extremities.

The use of artificial intelligence in the analysis of sports performance: a review of applications in human gait analysis and future directions for sports biomechanics.

Computers have played an important supporting role in the development of experimental and theoretical sports biomechanics. The role of the computer now extends from data capture and data processing through to mathematical and statistical modelling and simulation and optimization. This paper seeks to demonstrate that elevation of the role of the computer to involvement in the decision-making process, through the use of artificial intelligence techniques, would be a potentially rewarding future direction for the discipline. In the absence of significant previous work in this area, this paper reviews experiences in a parallel field of medical informatics, namely gait analysis. Research into the application of expert systems and neural networks to gait analysis is reviewed, observations made and comparisons drawn with the biomechanical analysis of sports performance. Brief explanations of the artificial intelligence techniques discussed in the paper are provided. The paper concludes that the creation of an expert system for a specific well-defined sports technique would represent a significant advance in the development of sports biomechanics.
