[Complete rotator cuff lesions in athletes].

The causal etiologies of complete rotator cuff lesions are described. Handball, volleyball, rugby, throwing and putting disciplins, but also tennis, swimming, golf and artistic gymnastics are regarded as sports especially straining the periarticular structures of the shoulder joints. In the period from November 1980 to April 1986, 72 shoulder joints with complete rotator cuff lesions were treated surgically (bilaterally in three cases). The 69 patients comprised 16 recreational and 11 competitive sportsmen. An average of 2.4 years after the operation, 66 shoulder joints (91.6%) could followed up clinically and sonographically with simultaneous use of a 100-point-score. Good and very good results were shown in 70% of the cases.

[Epidemiology of sports injuries. A 15 year analysis of sports orthopedic ambulatory care].

Analysis of a special outpatient department of sports orthopaedics covers a 15-year period (1972-1986); the department studies by us was initially part of the Orthopaedic Hospital of the University of Heidelberg, whereas later on we continued our studies at the Sports Clinic in Stuttgart-Bad Cannstatt. A grand total of 13,296 sportsmen treated in these departments was assessed, having a total of 15,212 injuries or lesions/damage due to sports activities. All cases were systematically recorded right from the beginning. In 1986, 19.3 million Federal German sportsmen were members of the Federal German Sports Association (DSB), i.e. 31.4% of the populations. The number of sports-related accidents that occurred per year is estimated at 1.5 million, i.e. more than 15% of the total number of accidents. The absolutely highest incidence rate of accidents is seen in popular sports such as football (i.e. "soccer", the most widely practised sport in the Federal Republic), skiing, handball, volleyball, track-and-field athletics, and gymnastics and physical training. The major part of the accidents involves the lower extremities (66.6%), followed by the arms (22.8%) and the vertebral column (4.7%). In respect of diagnoses, lesions of capsular ligaments are by far the most frequent ones. "Distortions" are stated to occur in 32.9% of the cases, severe injuries such as fractures, luxations and ruptures of ligaments representing a total of 33.6%. The incidence rate of contusions is increasing (12.6%), and so is that of lesions of the muscles and tendons (10.4%). 76.5% of the injured persons are men, with an age bracket peak at 20-29 years, followed by the group of 10-19 years. Analysis of the lesions yields valuable pointers to possibilities of accident or injury prevention within the individual sports categories.

[Sports injuries of the nervous system].

Almost 1% of all Germans suffer sports injuries each year, almost 5% of all peripheral nerve lesions are due to sports. A review is given on various activities detailing the specific risks for traumata of the central and peripheral nervous system. Specifically these are volleyball, handball, basketball, American football, soccer, bowling, hockey, baseball, tennis, golf, javelin, fencing, wrestling, judo, boxing, running, jumping, dancing, mountain climbing, weight lifting, gymnastics, horse-back riding, swimming, rowing, skiing, skating, shooting, (motor) biking, car racing, flying, and sports for the disabled. The knowledge of typical traumata should enable the neurologist to rapidly and reliably recognize related lesions and to contribute to their prevention or improvement.

[Asymmetry of posture and truncal musculature following unilateral arm amputation--a clinical, electromyographic, posture analytical and photogrammetric study].

Unilateral upper limb amputation causes changes in statics of the spine. As a result asymmetrical posture of the spine, muscular asymmetries follow. In this study a population of upper limb amputees (above and below elbow amputees) is examined by clinical, electromyographical analysis and gait analysis. Upper limb amputations cause in correlation to weight loss a shift of the trunk to the side of the amputation, a scoliosis with a bowing to the side of the amputation, an elevation of the shoulder on the amputation side and a torsion of the trunk. Muscular asymmetries result from loss of function (muscles of the arm, M. latissimus, M. trapezius) and by shifting of the center of gravity. In order to get the center of gravity over the legs, the amputee compensates the loss of weight by shifting the upper trunk to the side of the amputation. As a result the shift of the segmental center of gravity at the lumber height to the side of the normal arm with muscular asymmetry in the erector trunci lumbalis results. As well we saw an overactivity of musculus glutaeus medius and resulting stress of the amputation sided hip joint. There was a remarkable difference between above and below elbow amputees caused by differences in weight loss. Muscular and static asymmetries in amputees who lost their arm only a short period before could be reduced by compensating the weight loss. Results for technical orthopaedic fitting and stress on gymnastic procedures to compensate these statistical problems are discussed.

[Distribution pattern of subchondral mineralization in the glenoid cavity in normal subjects, athletes and patients].

To get information on the stresses acting on the shoulder joint, the distribution of subchondral mineralisation was examined by means of CT-Osteo-absorptiometry in the glenoid cavity in healthy people, athletes and patients. In young persons two density maxima are found ventrally and dorsally older persons, however, show a centrally located maximum which suggests a different joint mechanics in different ages depending on the decreasing physiological incongruence. In gymnasts the overall mineralisation is significantly higher, maxima are found centrally or shifted dorsally. In patients with recurrent dislocation of the shoulder or instability the zone of highest density is shifted to the edges of the glenoid cavity indicating that the prevailing position of the resultant force is excentric. By means of CT-Osteo-absorptiometry these individual patterns of mineralisation can be displayed in the living and can give information on the individual mechanical situation ("loading history") of a joint.

[An increased risk of kinesitherapy in silent myocardial ischemia?].

The effect of three-week standardized physical training on exercise-induced ischaemia was investigated in patients with silent ischaemia after myocardial infarction. 24-hour monitoring and exercise ECGs before and after the period of physical training, were undertaken in 32 men (mean age 53.6 +/- 8.1 years) with angiographically proven coronary heart disease. The protocol of the standardized exercise included bicycle ergometry, gymnastics, breathing and movement exercises, as well as nonstandardized walking or hiking. Following the training period the number of ischaemic episodes fell from 90 to 72 for the group as a whole and that of the asymptomatic episodes from 79 to 64. The number and severity of ventricular arrhythmias were similar during silent and symptomatic ischaemia. There was a significant increase in duration of exercise until reaching the ischaemia threshold (mean exercise duration 4.7 +/- 2.1 vs 5.9 +/- 2.5 min; P = 0.0007). There was no increased risk concerning ventricular arrhythmias.

[24-hour blood pressure profile: reproducibility of automatic ambulatory measurement].

Twelve patients (8 males, 4 females; mean age 53 [43-60] years) who were undergoing rehabilitation treatment after myocardial infarction were studied to ascertain the reproducibility of ambulatory automatic blood pressure measurements. All were in the last stage of a rehabilitation programme (tolerance to ordinary activity; symptom-free exercise at 75 W). Within two weeks 2, 3 or 4 blood-pressure profiles over 24 hours (total of 32 readings) were obtained by automatic measurement and the records and mean values were compared. Single mild stresses, such as gymnastic exercise or visit to the doctor, were identifiable on the records, but did not alter the overall profile or mean values. Normotensives, hypertensives and borderline hypertensives had 24-hour profiles which were nearly identical with regard to the curve "envelope", day-night profile and mean values in the individual patients. Mean values of diastolic and systolic pressures day by day in each patient showed no deviations greater than 5 mm Hg. Therapeutic measures were recognizable by parallel fall of the curve "envelope", as well as by a reduction in mean value.--At least in these selected patients a single 24-hour profile would in principle have sufficed to describe blood pressure behaviour.

Overuse injuries of the upper extremity in the competitive athlete: magnetic resonance imaging findings associated with repetitive trauma.

Overuse injuries are a very common cause of pain in athletes, accounting for a significant loss of training time and missed competitions. Magnetic resonance imaging (MRI) is playing an increasing role in facilitating the expeditious and safe return of these individuals to their preinjury level of physical performance by allowing accurate diagnosis. Sports physicians are increasingly relying on the exquisite anatomic detail afforded by this technique to formulate diagnoses that assist with the optimal management of these athletic injuries. Some upper extremity overuse entities are well recognized; two examples are medial epicondylitis, classically appearing in baseball pitchers, and lateral epicondylitis, in tennis players. Other less well-known injuries of the upper extremity, such as intersection syndrome in rowers and distal clavicular stress fractures in weightlifters, are frequent occurrences in certain circles of athletes. The following article is a pictorial review of the MRI findings of upper extremity overuse injuries encountered in the competitive athlete, with an emphasis on the sports scenarios in which they occur. We will depict mechanisms of injury and applicable anatomy and show characteristic imaging findings. A wide range of entities are addressed, including but not limited to overuse injuries occurring in baseball, swimming, gymnastics, weightlifting, bowling, and cycling.

Emergency visits for sports-related injuries.

STUDY OBJECTIVE: We sought to estimate the effect and magnitude of patients with sports-related injuries presenting to hospital emergency departments in the United States and to examine differences in patient and visit characteristics between sports- and nonsports-related injuries. METHODS: Data from the 1997 and 1998 National Hospital Ambulatory Medical Care Survey, a national probabilistic sample of 496 US hospital EDs, were combined to examine emergency visits for sports-related injuries. Data from 16,997 sample ED encounter records for injuries that included narrative cause of injury text were analyzed. Narrative text entries were coded to 1 of 84 sport and recreational activity codes. Sample weights were applied to provide annual national estimates. Estimates of sports-related injury visits were based on 1,775 records with an assigned sports-related activity code. RESULTS: There were an average annual estimated 2.6 million emergency visits for sports-related injuries by persons between the ages of 5 and 24 years. They accounted for over 68% of the total 3.7 million sport injuries presented to the ED by persons of all ages. As a proportion of all kinds of injuries presenting to the ED, sports-related injuries accounted for more than one fifth of the visits by persons 5 to 24 years old. The use rate was 33.9 ED visits per 1,000 persons in this age group (95% confidence interval 30.3 to 37.5). The sports-related injury visit rate for male patients was more than double the rate for female patients (48.2 versus 19.2 per 1,000 persons between 5 and 24 years of age). Visits from sports-related activities for this age group were more frequent for basketball and cycling compared with other categories (eg, baseball, skateboarding, gymnastics). Compared with nonsports-related injuries for this age group, sports-related injuries were more likely to be to the brain or skull and upper and lower extremities. Patients with sports-related injuries were more likely to have a diagnosis of fracture and sprain or strain and less likely to have an open wound. They were also more likely to have diagnostic and therapeutic services provided, especially orthopedic care. CONCLUSION: Sports-related activities by school-age children and young adults produce a significant amount of emergency medical use in the United States. The ED is an appropriate venue to target injury prevention counseling.

The effects of different pause types on neck and shoulder EMG activity during VDU work.

Surface electromyographic recordings on the right side from the descending part of the trapezius muscle and from the levator scapulae muscle and discomfort ratings were assessed for twelve female word processor operators. The operators were studied during three work periods of 30 min each. Three different kinds of pauses, active pauses with pause gymnastic movements, passive pauses with rest and diverting pauses, were introduced into the work every six minutes. The static muscular load was low and about the same for the three work periods. High contraction levels with a duration of at least 1% of the registration time differed significantly between the three types of pauses, reflecting the activity during the pauses itself. Active pauses could thus change the muscle activity pattern. There was a tendency to prefer pauses with activity to passive pauses.

The Influence of Skill and Intermittent Vision on Dynamic Balance.

Two experiments are reported in which expert and novice gymnasts were required to walk across a balance beam as quickly as possible in various vision conditions. In Experiment 1, experts walked faster than novices in all vision conditions, showing the greatest superiority when vision was completely eliminated. Novices were more dependent on vision and were able to maintain their performance as long as a visual sample was available every 250 ms (i.e: 4-Hz samples).The results of Experiment 2 indicate that differences between expert and novice performers in the no-vision condition were not related to the use of a short-term visual representation of the movement environment. Our movement time findings are problematic for specificity of learning models of skill acquisition. As well, film data collected in Experiment 2 were not consistent with models that propose a transition from closed-loop to open-loop control.

Sports injuries to the upper extremity. How to recognize and deal with some common problems.

Upper extremity syndromes caused by a single stress or by repetitive microtrauma occur in a variety of sports. The throwing motion, long-distance swimming, bowling, golf, gymnastics, basketball, volleyball, and field events can repetitively stress the hand, wrist, elbow, and shoulder. The biomechanical evaluation of racquet handling, throwing, and swimming motions has progressed considerably, and the future looks promising for better identification and prevention of sports injuries due to stress. These insights will help the physician more adequately understand and treat athletic injuries. As for the present, we must recognize athletic injuries for what they are--debilitating single or repetitive trauma to active persons who want a rapid return to their sport. The goal of both the injured athlete and the treating physician must be 100% recovery; compromise in treatment is not warranted. To achieve the best results, the physician should emphasize to the athlete, coach, and parent that healing is a matter of time.

Vertical jumping height and horizontal overhead throwing velocity in young male athletes.

The purpose of this study was to examine the effects of calendar and skeletal age, anthropometric dimensions, training history and their interactions on vertical jumping height and horizontal overhead throwing velocity in a cross-section of 318 young male athletes (age range 9-16 years) participating in cross-country skiing (n = 70), basketball (n = 40), apparatus gymnastics (n = 19), ice hockey (n = 50), track and field (n = 89) and wrestling (n = 50). Vertical jumping height was measured with four different loads held on the shoulders and then interpolated for loads representing 0 and 40% body mass. Horizontal overhead throwing velocity using both hands was determined for seven balls of different weights and then interpolated for weights representing 1 and 5% body mass. Both vertical jumping height and overhead throwing velocity were found to increase (P < 0.01) from the skeletally youngest to the oldest cohort when the effects of body height and mass were controlled. The inter-event comparisons did not reveal statistically significant differences in respect of vertical jumping height. Also in the overhead throwing tests, the inter-event differences were small, although the analysis of variance revealed statistically significant (P < 0.001) differences for the skeletal age cohorts of 13 and 14 years. While the quantity of training had no effect on vertical jumping height, it explained the results in the overhead throwing test. The effects of training on vertical jumping and horizontal overhead throwing among adolescent athletes were considered to be small, while maturational processes and anthropometric development followed by increase in calendar age were deemed to be of greater importance.

Validity of the Mellits and Cheek method for body-fat estimation in relation to menstrual cycle status in athletes and non-athletes below 22 per cent fat.

The present experiment tested the hypothesis that 22% body fat based on the Mellits and Cheek (1970) regression equation is a minimum or 'trigger' level of fatness required to maintain regularity of menstrual cycles. The validity of the regression equation was cross-validated against densitometric estimates of body fat in 30 athletes (track, gymnastic, crew) and 30 non-athletes who were below 22% fat. For the total sample, the validity correlation was r = 0.47 between body fat (density) and body fat (regression equation); it was r = 0.75 for athletes and r = 0.47 for non-athletes. For all subjects, 60% had regular menses, 27% were oligomenorrheic and 13% were amenorrheic. The lowest body fat (density) was 12.8% for an athlete with a regular cycle and 12.2% for an oligomenorrheic athlete. The results show that: the Mellits and Cheek (1970) height-weight based regression equation to determine fatness is not valid for women below 22% fat, and 13% body fat (not 22%), should be considered an upper-bound estimate of a minimum level of fatness associated with normal ovulatory cycles.

Quality of life in childhood asthma: use of the Paediatric Asthma Quality of Life Questionnaire in a Swedish sample of children 7 to 9 years old.

To validate a Swedish translation of the Paediatric Asthma Quality of Life Questionnaire (PAQLQ) and to study determinants of asthmatic children's quality of life, seventy-one 7-9-y-old children and their families were approached. Sixty-one children (86%) participated, 36 boys and 25 girls: 11 children with mild, 40 with moderate and 10 with severe asthma. The mean age was 8.7 y. Most commonly restricted activities during the week preceding the investigation were running (74%), gymnastics (30%), walking uphill (26%), playing football (20%) and shouting (13%). Parental rating of symptoms (Spearman's rho = -0.40, p = 0.001), percentage of expected peak flow rate (PEFR) (rho = 0.30, p = 0.009) and physicians' grading (mild, moderate and severe asthma, p = 0.047) all correlated significantly with PAQLQ scores. Younger children reported more impairment of QoL, as did children of parents not sharing household. Sex or presence of eczema or rhinoconjunctivitis did not significantly affect the scores. Children suffering from food allergy scored less impairment of QoL. The instrument was easy to administer, was well accepted by the children and had acceptable internal consistency.

Some ideas, whether right or wrong, seem never to die, whatever might be the general evolution of knowledge, of science, or simply of good common sense. This is exactly the case with physical education or sports. For centuries, and especially since the middle of the nineteenth century, its advocates have fought for recognition of its all-round virtues, taken as a concept. But to attain a high level of recognition, not only in society but in official government circles, certain conditions were necessary. Education as a whole, around the middle of the nineteenth century, had to be strict and similar to military drill to be considered efficient, although the French middle classes and bourgeoisie had very little taste for the military. Although they admired physical prowess they had a horror of regimentation. But later on, when the Prussians so easily defeated Austria, feelings of doubt in French superiority began to spread, and a handful of theoreticians of physical exercise tried to show that to combat the so-called degeneration of the race, it was essential to impose a system of education in which physical exercise, coupled with military drill, still had an important place. As scientific arguments they referred to the theories of evolution and its then accepted principle, according to Lamarck, or the transmission of acquired properties and character. Darwin was still unknown in France at that time. These zealous advocates succeeded in convincing the Minister of Public Education, Victor Duruy, to include gymnastics in the normal course of studies in all schools, and by 1869 one can say that a craze for all types of physical exercise and sport had spread into many levels of society. That was the start of a never-ending movement which has passed through various stages of evolution corresponding to the changes in society itself. It has therefore changed its methods, its ways, its forms, but the overall principle remains the same, in spite of the improved understanding of human physiology for instance. Huge amounts of energy and money were spent on realizing this theory: politicians, educators, the military, religious authorities, men of distinction, all fought for the best possible application of this miraculous principle which was believed to cure all ills in this world. Was it really worthwhile? Was it possible to expect objectively measurable results on a national scale if the social factors - such as standards of living, hygiene, working hours, urban conditions - were not taken into account? The history of this element requires a deep understanding of the evolution of most of the factors which make up real life in a country such as France, which experienced various stages in a industrial revolution as well as many political changes. In spite of this evolution, one must acknowledge that false beliefs survived well into the 1940s, and furthermore, physical exercise, whatever its form, still belongs in many ways to hedonism and is therefore difficult to impose as a universal solution to political problems. As a democracy, France could not accept militarization.

Growth and pubertal development in children and adolescents: effects of diet and physical activity.

The longitudinal growth of an individual child is a dynamic statement of the general health of that child. Measurements should be performed often and accurately to detect alterations from physiologic growth. Although any single point on the growth chart is not very informative, when several growth points are plotted over time, it should become apparent whether that individual's growth is average, a variant of the norm, or pathologic. Somatic growth and maturation are influenced by several factors that act independently or in concert to modify an individual's genetic growth potential. Linear growth within the first 2 y of life generally decelerates but then remains relatively constant throughout childhood until the onset of the pubertal growth spurt. Because of the wide variation among individuals in the timing of the pubertal growth spurt, there is a wide range of physiologic variations in normal growth. Nutritional status and heavy exercise training are only 2 of the major influences on the linear growth of children. In the United States, nutritional deficits result from self-induced restriction of energy intake. That single factor, added to the marked energy expenditure of training and competition for some sports, and in concert with the self-selection of certain body types, makes it difficult to identify the individual factors responsible for the slow linear growth of some adolescent athletes, for example, those who partake in gymnastics, dance, or wrestling.

Muscle strength in obese elderly women: effect of recreational physical activity in a cross-sectional study.

BACKGROUND: Muscle strength (MS) may be impaired in obese persons, and this impairment may be a consequence of both obesity and low physical fitness. OBJECTIVE: We investigated whether MS differed between obese [body mass index (BMI; in kg/m2 > 29], normal-weight (BMI = 24-29), and lean (BMI < 24) elderly subjects and compared the MS of sedentary and active subjects according to their BMI group. DESIGN: The study included 215 obese [ (+/- SD) age: 80.0 +/- 3.5 y; BMI: 31.9 +/- 2.6], 630 normal-weight (age: 80.2 +/- 3.7 y; BMI: 26.3 +/- 1.4), and 598 lean (age: 80.7 +/- 3.5 y; BMI: 21.6 +/- 1.8) women with good functional ability. A cross-sectional design was used. Anthropometric measures (weight, height); measures of appendicular skeletal muscle mass (by dual-energy X-ray absorptiometry), isometric knee and elbow extension (by statergometer), and isometric handgrip strength (by dynamometer); and data on health status and self-reported recreational physical activity (RPA: walking, gymnastics, cycling, swimming, gardening) were collected. RESULTS: Absolute (unadjusted) MS was higher in obese than in lean women (P < 0.01), except for handgrip strength (P > 0.05). When adjusted for age, height, RPA, pain, depression, and appendicular skeletal muscle mass, MS did not differ significantly between obese, normal-weight, and lean subjects, except for knee extension (significant interaction effect with RPA; P = 0.01). With increasing BMI, lower limb strength did not change in the sedentary women but increased in active (> or = 1 h/wk in > or = 1 RPA for > or = 1 mo) women. All adjusted MS measures in active participants were significantly higher (P < 0.001) than those in their sedentary peers. CONCLUSION: The adjusted MS of elderly women is not associated with obesity but is higher in active subjects than in sedentary ones, especially in the lower limbs of obese subjects.
