To assess use of imagery intervention in performance of two tennis motor skills the quasi-experimental design included a pre- and posttest and a control group. The tennis service shot and service receiving skill were selected as representative of open and closed skills, respectively. 48 subjects, male tennis players, whose ages ranged from 16 to 18 yr. (M = 17.2), were divided into two groups: (1) Technical practice only which was used as control group and (2) Imagery group who received both imagery and technical practice. Analysis of covariance showed a significant main effect for the imagery intervention on the closed skill (p = .002). Findings suggest that imaging a positive outcome may be more powerful in improving performance of closed skill movements than of open skill movements.

Effect of pre- and postcompetition emotional state on salivary cortisol in top-ranking wrestlers.

Ricardo Weigert Coelho; Birgit Keller; Andressa Melina Becker da Silva

The purpose was three-fold: (1) to investigate the effect of baseline, precompetition, and postcompetition stress on salivary cortisol levels in top-ranking Brazilian wrestlers (N = 17) participating in a national competition; (2) to estimate correlations among three stress measures (perceived stress, salivary cortisol, and physiological stress reaction); and (3) to compare cortisol concentrations between losers and winners. Salivary cortisol was collected at baseline, pre-, and postcompetition. Physiological stress reaction and perceived stress scores were measured just before warm-up for the competition. Analysis showed a significant main effect for testing time. Correlations among the stress measures were not significant. Analysis of covariance between the winners (n = 10) and the losers (n = 7) was also not significant. Salivary cortisol concentrations increased after the intense exercise of competition. The wrestlers did not perceive any physiological effects.

The effect of multimodal imagery on anxiety and perceived stress was investigated in 46 male tennis players (16 to 18 yr.; M = 17.0, SD = 0.8). There were two groups, a multimodal imagery group and a control imagery group. The quasi-experimental design included pre- and post-treatment administrations of the 27-item Competitive State Anxiety Inventory to assess anxiety and the Perceived Stress Scale to assess stress. Analysis showed a statistically significant multivariate difference between the multimodal imagery and control groups on measures of cognitive anxiety, self-confidence, and perceived stress. Imagery plays a role in handling some specific types of anxiety and stress.

Relação entre a personalidade e lesões musculares em atletas de tênis de campo

Birgit Keller; Ana Maria Braga; Ricardo Weigert Coelho

INTRODUCTION: The personality of an individual is the result of a complex network of influences of various independent factors such as biological and psychological constitution, beyond the influences of social, environmental and cultural aspects where he/she live. It is the integration of these parts that when interacting, make the whole. OBJECTIVE: To verify whether there is a cause-effect relationship among personality traits, gender and injury in sports. METHOD: The sample consisted of 60 athletes with mean age of 15.6 (SD = 1.5) years old, being 35 male athletes and 25 female athletes from the children and youth category, participating in field tennis tournaments of the Federation of Santa Catarina and Parana. Data were collected with the application of the Factor Personality Inventory - FPI. MANOVA and ANOVA at a level of p < 0.05 were used for data processing. RESULTS: Were significant to the variable damage with aggression (p = 0.01) and heterosexuality (p = 0.00). Concerning gender, there were significant differences with intraception (p = 0.02); succorance (p = 0.02), dominance (p = 0.004), autonomy (p = 0.03) and heterosexuality (p = 0.00). CONCLUSION: That aggressiveness is an important personality trait to be considered to control, prevent and reduce the incidence of injuries in tennis athletes.

O objetivo da pesquisa foi determinar a prevalencia de mulheres com sintomas de bulimia nervosa frequentadoras de academia de ginastica e verificar, dentre as praticantes que apresentam tracos bulimicos, qual a frequencia de utilizacao do exercicio fisico como forma compensatoria. Participaram do estudo 197 mulheres matriculadas em academias de ginastica da cidade de Marechal Cândido Rondon – PR (28,7±9,9 anos). Para avaliar o quadro de bulimia utilizou-se o Teste de Investigacao Bulimica de Edingurgh (BITE) e uma anamnese estruturada pelos pesquisadores para atender interesses do estudo. Na analise dos dados foi utilizada a estatistica descritiva e a frequencia amostral pelo programa estatistico SPSS for Windows 11.5. A prevalencia de sintomas de bulimia foi de 3%. A prevalencia de tracos bulimicos foi de 11,2%. Dos individuos que apresentaram tracos bulimicos, 59,1% afirmaram praticar exercicio fisico apos episodios de alimentacao exagerada. Estes resultados podem indicar que esse comportamento compensatorio atraves da pratica de exercicio fisico pode levar as mulheres a procurar as academias de ginastica.

BACKGROUND AND OBJECTIVES: Failed back surgery syndrome refers to a condition in which a patient has undergone back surgery with a poor outcome. This syndrome leads to losses in daily living activities and hinders the return to physical exercise. The objective of this study was to analyze the relation between chronic low back pain and functional capacity and the physical activity level of these patients. METHODS: Cross-sectional study comprising 57 patients, mean age 51.07±12.93 years, who underwent low back surgery. These patients were divided into two groups, according to the presence of chronic low back pain. All patients filled in a questionnaire that covered demographic data, visual analog scale for pain, Rolland-Morris Questionnaire to evaluate functional incapacity and International Physical Activity Questionnaire to measure physical activity level. RESULTS: The following predominated: women (77%), obese (49%), surgery for spinal disc herniation (80%), underwent one low back surgery (52%). Patients with chronic low back pain refer a greater perception of disability and 81% of this group showed an average of 3.53±3.51 points in Roland-Morris. Chronic low back pain had no influence on the different levels of physical activity demonstrated in patients with chronic low back pain and results of the International Physical Activity Questionnaire showed no significant difference between the groups (p=0.54). CONCLUSION: These findings indicate that there were other factors beyond chronic pain interfering with the physical activity level in these groups and further studies to explore lifestyle, physical exercise adherence and other dimensions of pain are still needed. Results contribute to the understanding and management of patients with chronic low back pain.

The fear of falling is one of the main problems with subjects after stroke. Imagery could be one succeed experience to decrease this issue. The aim of this study was to verify the effect of a short-time imagery intervention in fear of falling in subjects after stroke. Seven individuals affected by stroke participated in the study. The Falls Efficacy Scale International (FES-I-Brazil) were used before (PRE), after (POST) and seven days after intervention (RET). Four session of familiarization and six of imagery were performed. There were no difference in FES-I-Brazil score after intervention (p=0.46), except in up/down stairs task (PRE and POST, p=0.04; PRE and RET, p=0.01). Although, the improvement in up/down stairs task, no more changes were found in the scale items, which could represent a relatively reduced effect of short-time imagery intervention.
