Spatial ability in classic dancers and their perceptual style.

The relation between spatial ability (body orientation and body awareness) and field dependence/independence was assessed by measuring performance on the Embedded Figures Test and WISC or WAIS Block Design at four different training levels in classical ballet, beginners to advanced, and a control group with no training in ballet, gymnastics, or sports (n = 70). No significant correlation was found between perceptual style or Block Design performance and body orientation or body awareness at any of the four levels of training. No significant differences were observed between the advanced group and the control group. Training in a particular type of spatial skill such as orientation within surrounding space was not related to the skill required to manipulate an abstractly represented space.

Perceived relative importance of psychological and physical factors in successful athletic performance.

Ratings of the perceived relative importance of psychological and physical factors for successful athletic performance were obtained from 29 men and 53 women in sports of track, swimming, soccer, volleyball, basketball, gymnastics, baseball or softball, tennis, diving, and golf, by level of competition (high school, college, and professional), and sex of athlete. The over-all rating of the relative importance of psychological factors was 39%. Significant differences in the ratings of the relative importance of psychological factors were found for sport, level, sex, sport x level, and level x sex. Ratings of the relative importance of psychological factors for successful performance in various sports increased in the order listed above. The significant effect for level and interaction of sport x level were accounted for primarily by the higher ratings given to professional golf. The significant effect of sex and the interaction of sex x level were attributable to higher ratings of the importance of psychological variables for high school women athletes as compared to high school men athletes.

Relation between sport activity and mental rotation: comparison of three groups of subjects.

The aim was to observe the relation between sport activity and performance on a mental image-transformation task. A classical mental rotation task using abstract stimuli was administered to three groups: (a) gymnasts who used mental and physical rotations in their practice, (b) athletes whose activities required very little motor rotation, and (c) nonathletes. Both sport groups performed similarly and obtained significantly shorter response times than those of the nonathletes. We suggest that the regular practice of spatial activities, such as sports, could be related to the spatial capacities of the participants.

Field dependence-independence in complex motor skills.

This study analyzed the relationship between field dependence-independence and complex motor skills. According to the requirements of each sporting activity, subjects' motor system can be mainly controlled through exteroceptive or proprioceptive information. Sport performances require the athlete to disembed himself, other players, or the ball from the background, and decision-making appears to require cognitive restructuring. 26 athletes (13 men and 13 women) involved in acrobatic sports (gymnastics, trampoline, half-pipe snowboard, synchronized 3-m springboard, acrobatic rock, skateboard, and free skating) and 26 athletes (13 men and 13 women) involved in individual racket sports (tennis and table-tennis) completed the Group Embedded Figures Test. Participants (at least 10 years of practice) were from 16 to 35 years of age (M=22.0, SD=3.1). No significant difference among athletes on scores for field dependence-independence was evidenced given this expertise, sex, or age. Significantly higher scores were obtained by athletes in acrobatic sports, indicating that they tended to be predominately more field-independent whereas the lower scores were obtained by tennis and table-tennis players.

Relationship between achievement goal constructs and physical self-perceptions in a physical activity setting.

The relations of achievement goal theory constructs and physical self-perceptions were explored with 225 students (91 men, 109 women, and 25 nonindicators; M age=23.5 yr., SD=9.2), enrolled in basic physical activity classes (aerobics, weight training, modern dance, badminton, yoga, tai chi, basketball, racquetball, gymnastics, bowling, aquatone, and step aerobics) in a university setting. Goal orientations (Task and Ego Orientation in Sport Questionnaire), perceptions of the motivational climate (Perceived Motivational Climate in Sport Questionnaire-2), and physical self-perceptions (Physical Self-perception Profile) were assessed. Data were analyzed separately by sex. Ego orientation was the only predictor of Physical Self-perceptions in men, accounting for between 12 and 15% of the variance in Physical Self-worth, Sport Competence, Physical Conditioning, and Body Attractiveness. Constructs of achievement goal theory were not predictive of Physical Self-perceptions in the women. The results are discussed in light of achievement goal theory and the nature of the sample.

Modalities of submaximal exercises on ratings of perceived exertion by young girls: a pilot study.

This pilot study compared the rating of perceived exertion scores (RPE) in young girls for two modalities of exercises (running vs cycling) performed at the same absolute heart rate. 23 girls, ages 8 to 11 years, from a gymnastic club performed graded, intermittent, and submaximal running and cycling exercises at a similar absolute heart rate (+/-5 bpm). These exercises consisted of three stages of 3 min. duration separated by 1-min. recovery intervals. RPE was estimated using the Children's Effort Rating Table scale at the end of each stage of each exercise. Mean ratings were only significantly different during cycling, compared to running for the Stage 3 (cycling 5.3+/-2.7 and running 7.0+/-1.9, p < .05). During low exercise intensity, measured as heart rate, the modality of exercise does not seem to affect RPE. In contrast, with high heart rates, RPE are higher during cycling than running, so it is necessary to take account of the type of exercise.

On the causes of traumatic dental injuries with special reference to sports accidents in a sample of Finnish children. A study of a clinical patient material.

Causes of traumatic dental injuries were studied in a sample of 321 Finnish children with injured permanent incisors. In girls the most common cause was falls (36.7%), and with boys sports (33.6%). Among the sports accidents, gymnastics dominated for girls and ice hockey for boys. Bicycling was also a markedly frequent cause of accidents for boys. The proportion of severe injuries was significantly higher in ice hockey and bicycling accidents than in other sports accidents.

[The effects of pulmonary rehabilitation with chronic obstructive pulmonary disease (COPD)].

It is controversial whether pulmonary rehabilitation is effective in patients with chronic obstructive pulmonary disease (COPD). To test the effect of pulmonary rehabilitation, 7 patients with COPD (aged 76.0 +/- 2.6 years) were enrolled in pulmonary rehabilitation program for 6 weeks. The program consisted of relaxation, pursed lip breathing, diaphragmatic breathing, panic control, muscle stretch gymnastics, and exercise training. The distance of the 6-minute walking test increased significantly from 246.4 +/- 38.0 (m) to 304.3 +/- 28.4 (m) (p < 0.05). The minimum SpO2 during the 6-minute walking test increased from 86.0 +/- 2.8 (%) to 90.1 +/- 1.3 (%) and dyspnea as measured with Borg scale decreased from 5.6 +/- 1.1 to 4.6 +/- 0.5, although they were not significantly different. These results suggest that pulmonary rehabilitation might improve exercise tolerance in elderly patients with COPD.

[A case of chronic obstructive pulmonary disease (COPD) followed by pulmonary rehabilition].

We report a 75-year-old woman with chronic obstructive pulmonary disease (COPD) suffering from cough, sputum, high-grade fever and dyspnea on effort. Her chest radiograph revealed an infiltrative shadow in the right lower lung field and her laboratory data showed marked inflammatory changes. Her arterial blood gas analysis showed marked hypoxemia and hypercapnia. After her laboratory data and general condition improved, we performed pulmonary rehabilitation for the patient for about 6 weeks. The program consisted of pursed lip breathing, diaphragmatic breathing, muscle stretch gymnastics, and walking. The 6-minute walking test distance increased from 170 m to 280 m. The minimum SpO2 during the 6-minute walking test increased from 88% to 91%. (O2 3 L/m) After discharge, she continued to receive home care from a visiting nurse specialized in respiratory medicine and 24 hour-monitoring of O2-compliance at home. She has not experienced acute exacerbation or re-hospitalization for 1 year. We conclude that home care service is effective to maintain stable conditions such as state of breathing, SpO2, vital signs, and activities of daily living for elderly COPD outpatients.

Duration of mentally simulated movement: a review.

The authors review studies of mentally simulated movements. In automatic or cyclical movements, actual and motor imagery (MI) durations are similar. When athletes simulate only dynamic phases of movement or perform MI just before competing, however, environmental and time constraints lead to an underestimation of actual duration. Conversely, complex attention-demanding movements take longer to image. Finally, participants can modify the speed of MI voluntarily when they receive specific instructions. To complete the available data, the authors compared imagined and actual durations in tennis and gymnastics. Results showed systematic and disproportionate overestimation of actual duration. The authors found a relationship between complex motor skills and MI duration. They discuss the factors leading to over- and underestimation and the hypotheses that could be tested.

Optical flow and viewpoint change modulate the perception and memorization of complex motion.

Participants observed a point-light character (PLC) performing a gymnastic movement. They either memorized the final PLC orientation from the initial viewpoint, to match it to a test posture (memory task), or judged whether the biological motion appeared continuous (perceptual task), despite a viewpoint change. The observer could be either static or virtually in motion (pan or track) while looking at the movement from the initial viewpoint. The presence of a spatial layout during virtual self-motion induced a global optical flow specifying the translational component of the PLC movement, rendering the event more predictable for the participants. A representational momentum effect was observed in the memory task, suggesting that when a visual stimulation, such as a PLC motion, is abruptly stopped, its dynamics survive. In contrast, structural and transformational invariants specifying the PLC motion were sufficient to solve the perceptual task accurately. Finally, both the remembering of the final posture and the perception of continuity degraded with an increase in viewpoint change due to tilt/slant posture orientation matching, indicating that orientation processes interfered with event perception.

Sports injuries in childhood.

Participation in youth sports is relatively safe. Injuries become more frequent as the child gets older, bigger, and achieves higher skill levels. At the high school and collegiate levels, football has the highest injury rate followed by wrestling and gymnastics. There is no risk-free sport, and children tend to select the sports they wish to participate in without considering injury rates. Pediatricians should take an active role in injury prevention when covering sporting events as team physicians and as spectators.

Lateral compression injuries in the pediatric elbow: Panner's disease and osteochondritis dissecans of the capitellum.

Lateral compression injuries of the elbow typically occur in throwing athletes and gymnasts. In the preadolescent and adolescent patient, these injuries predominantly include Panner's disease and osteochondritis dissecans. Panner's disease, an osteochondrosis of the capitellum, is a rare disorder that usually affects the dominant extremity in individuals younger than age 10 years. Symptomatic management of Panner's disease consisting of reduction of stressful activities of the elbow is usually sufficient to allow resolution. Although a prolonged period is required for healing, most patients demonstrate excellent long-term results. Osteochondritis dissecans of the capitellum typically occurs in adolescents and is associated with loose body formation. Panner's disease and osteochondritis dissecans likely represent a continuum of disordered endochondral ossification with presentation and prognosis dependent primarily on age at onset.

Direct catastrophic injury in sports.

Catastrophic sports injuries are rare but tragic events. Direct (traumatic) catastrophic injury results from participating in the skills of a sport, such as a collision in football. Football is associated with the greatest number of direct catastrophic injuries for all major team sports in the United States. Pole vaulting, gymnastics, ice hockey, and football have the highest incidence of direct catastrophic injuries for sports in which males participate. In most sports, the rate of catastrophic injury is higher at the collegiate than at the high school level. Cheerleading is associated with the highest number of direct catastrophic injuries for all sports in which females participate. Indirect (nontraumatic) injury is caused by systemic failure as a result of exertion while participating in a sport. Cardiovascular conditions, heat illness, exertional hyponatremia, and dehydration can cause indirect catastrophic injury. Understanding the common mechanisms of injury and prevention strategies for direct catastrophic injuries is critical in caring for athletes.

An isolated long thoracic nerve injury in a Navy Airman.

A palsy of the long thoracic nerve of Bell is a cause of scapular winging that has been reported after trauma, surgery, infection, electrocution, chiropractic manipulation, exposure to toxins, and various sports-related injuries that include tennis, hockey, bowling, soccer, gymnastics, and weight lifting. Scapular winging can result from repetitive or sudden external biomechanical forces that may either exert compression or place extraordinary traction in the distribution of the long thoracic nerve. We describe an active duty Navy Airman who developed scapular winging secondary to traction to the long thoracic nerve injury while working on the flight line. A thorough history and physical is essential in determining the mechanism of injury. Treatment should initially include refraining from strenuous use of the involved extremity, avoidance of the precipitating activity, and physical therapy to focus on maintaining range of motion and strengthening associated muscles, with most cases resolving within 9 months.

[Juvenile struma and development].

Different aspects of the juvenile struma development in children are studied. The object of the investigations were puplis: 260 with juvenile struma and 240--without, aged from 8 to 17. The following indices were used: 1. physical growth--height, bodyweight, growth rate, annual mark in gymnastics; 2. mental development--mean annual marks at school; 3. sexual development--menarche rhythm and duration of menses in girls. All data were processed statistically by rank, non-parametric, variation and despersion analysis. The author thinks that the juvenile struma does not influence the normal progress of growth but is significantly more frequent among rapidly growing-up girls. He concludes that faster parapuberal growth might be the cause of juvenile struma origination.

Growth and quality of life after living-related liver transplantation in children.

Fifty-six consecutive pediatric recipients surviving more than 3 yr after living-related liver transplantation (LRLT) were evaluated in terms of growth, quality of life (QOL) and need for maintenance immunosuppression. Significant improvement in Z-score for height and weight were observed at last follow-up, ranging from 3 to 6 yr after transplantation, although catchup height gain lagged behind recovery in weight (height: -1.77 pre-transplant to -0.77 post-transplant, p<0.001; weight: -1.12 pre-transplant to -0.18 post-transplant, p<0.0001). 82% (46) recipients have remained in good health and have an excellent QOL as assessed in the most recent 6 months; these children lead similar daily lives to normal healthy children, with daily school attendance and full participation in activities including gymnastics and hiking. 3.6% (2) recipients attended school regularly but were unable to participate in sporting activities. 14% (8) recipients remain home or hospital-bound due to persistent complications in the past 6 months, with only minimal school attendance. Less than 10% of recipients were taking steroids by 2 yr post-transplantation, although approximately half of the children were receiving low-dose maintenance steroids at 1 yr. The mainstay immunosuppressant was tacrolimus, with 68% (38) recipients receiving daily therapy, 8.9% (5) alternate-day, 8.9% (5) twice a week, and 5.4% (3) a single dose weekly or alternate weeks. 7.1% (4) recipients were withdrawn completely from all immunosuppressants, including tacrolimus, for various reasons. 8.9% (5) patients have needed multiple immunosuppressive agents over the last 6 months. In conclusion, LRLT restores growth and offers excellent quality of life in pediatric recipients. The majority of recipients require minimal, steroid-free, immunosuppression by 2 yr post-transplant, but the occasional recipient still needs intensive longterm immunosuppression.
