Diet Management

Weight control in contact sports implies an additional stress to competitors, mostly when strategies to reduce it are inadequate. The present work analyzes if a correct diet planning could decrease anxiety in competitors. The validated CSAI-2 questionnaire was used before and after the weight control with judo, karate and taekwondo competitors from both genders following a free diet vs those that followed a diet plan. Results indicated that the intensity for somatic and cognitive anxiety in the pre-weight event was lower in male and female competitors following a controlled diet. Regarding gender, no differences in anxiety intensity and directionality were observed between individuals following a free diet in the pre-weight event. Regarding sport discipline, judo and taekwondo practitioners presented higher somatic and cognitive anxiety than karate competitors did. Altogether, the correct control of the corresponding weight throughout the sports season decreases anxiety and increases self-confidence, allowing to the participants to focus on the contest objectives.

Outcome Scores

Male and female tennis players ( N = 100) completed the Competitive State Anxiety Inventory-2 about 1 hr. before playing singles and doubles matches. Multivariate analysis of variance of anxiety and self-confidence responses by match result indicated that winners of singles matches bad significantly lower scores on Cognitive Anxiety and higher ones on Self-confidence than losers. Winners of doubles matches had significantly higher Self-confidence scores than losers. Discriminant function analysis indicated that 72% of results for singles matches and 70% of results for doubles matches could be correctly classified from responses to the precompetition measures. A comparison of anxiety responses by playing condition indicated that, irrespective of the match outcome, scores on Cognitive and Somatic Anxiety were higher and scores on Self-confidence were lower before playing singles than before playing doubles. The findings suggest that precompetition scores on measures of anxiety provide significant indicators of performance in tennis but that responses vary for singles and doubles play.

The purpose of the present study was to examine the relation of verbal aggressiveness and state anxiety (somatic, cognitive, and self-confidence) in sports settings based on the ratings by volleyball coaches and their athletes. The sample consisted of volleyball athletes ( n = 208; 98 men and 110 women) and their coaches ( n = 20; 16 men and 4 women). Analysis showed that male volleyball players rated somatic anxiety higher and were more affected by the verbal aggressiveness of their coaches than female volleyball players. No mean differences were significant for male and female coaches on somatic or cognitive anxiety, self-confidence, or verbal aggressiveness. Also, correlation between subscale scores for male and female volleyball players and coaches was found. The correlations of verbal aggressiveness with self-confidence and anxiety were positive for these athletes, leading them to better behavior. This relationship needs further examination in sport settings.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.

Spinal muscular atrophy (SMA) is a genetically heterogeneous group of rare neuromuscular diseases and was until recently the most common genetic cause of death in children. The effects of 2-month nusinersen therapy on urine, serum, and liquor 1H-NMR metabolomes in SMA males and females were not explored yet, especially not in comparison to the urine 1H-NMR metabolomes of matching male and female cohorts. In this prospective, single-centered study, urine, serum, and liquor samples were collected from 25 male and female pediatric patients with SMA before and after 2 months of nusinersen therapy and urine samples from a matching healthy cohort (n = 125). Nusinersen intrathecal application was the first therapy for the treatment of SMA by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Metabolomes were analyzed using targeted metabolomics utilizing 600 MHz 1H-NMR, parametric and nonparametric multivariate statistical analyses, machine learning, and modeling. Medical assessment before and after nusinersen therapy showed significant improvements of movement, posture, and strength according to various medical tests. No significant differences were found in metabolomes before and after nusinersen therapy in urine, serum, and liquor samples using an ensemble of statistical and machine learning approaches. In comparison to a healthy cohort, 1H-NMR metabolomes of SMA patients contained a reduced number and concentration of urine metabolites and differed significantly between males and females as well. Significantly larger data scatter was observed for SMA patients in comparison to matched healthy controls. Machine learning confirmed urinary creatinine as the most significant, distinguishing SMA patients from the healthy cohort. The positive effects of nusinersen therapy clearly preceded or took place devoid of significant rearrangements in the 1H-NMR metabolomic makeup of serum, urine, and liquor. Urine creatinine was successful at distinguishing SMA patients from the matched healthy cohort, which is a simple systemic novelty linking creatinine and SMA to the physiology of inactivity and diabetes, and it facilitates the monitoring of SMA disease in pediatric patients through non-invasive urine collection.

AbstractIt is well known that soccer sport has the potential for high levels of stress and anxiety and that these are linked to Cortisol (C) variations. To date, much research has been devoted to understanding how Oxytocin (OT) can affect anxiety in response to a challenge. The aim of this study was to investigate, in 56 young male soccer players, the psychophysiological stress response 96 and 24 h before one soccer match of a tournament, in order to establish whether athletes who won or lost, show different levels of C and OT or expressions of competitive state anxiety subcomponents. We found that winners had significantly lower Cognitive anxiety and higher Self-confidence scores than losers. Also, significant differences between winners and losers in C and OT concentrations were observed, with higher OT levels in who has won and higher C levels in who has lost. Our results showed interesting associations between OT, C, anxiety feelings, and the outcome of competition.

Abstract Objective To evaluate factors associated with anxiety and the effect of simulation-based training (SBT) on student anxiety, self-confidence and learning satisfaction in relation to pelvic and breast examination. Methods A longitudinal study was conducted with 4th year medical students at the Universidade José do Rosário Vellano. A 12-item, self-report questionnaire on student anxiety at performing gynecological examinations was applied before and after SBT, with answers being given on a Likert-type scale. After training, the self-confidence levels and satisfaction of the students related to the learning process were also evaluated. Results Eighty students with a mean age of 24.1 ± 4.2 years were included in the study. Of these, 62.5% were women. Pre-SBT evaluation showed that students were more anxious at performing a pelvic examination than a breast examination (2.4 ± 1.0 versus 1.7 ± 0.8, respectively; p < 0.001). The primary reason for anxiety regarding both pelvic and breast examination was fear of hurting the patient. SBT significantly reduced student anxiety (2.0 ± 0.8 versus 1.5 ± 0.5, respectively; p < 0.001). The satisfaction and self-confidence of the students were found to be high (6.8 ± 0.3 and 6.0 ± 0.9, respectively), with no difference between genders. Conclusion The use of SBT in teaching students to perform pelvic and breast examinations resulted in reduced anxiety and increased self-confidence in a group of medical students of both genders, with high levels of satisfaction in relation to the training.

Background: Increasingly colleges and universities are utilizing Outdoor Orientation Programs (OOPs) to help incoming students assimilate into college life. These programs have shown promise in recent analyses for enhancing desired outcomes with particular consideration shown to pro-social behavior and retention outcomes. Purpose: To examine how effective OOPs are in preparing students for a successful college student experience, particularly with variables known to influence student success and commitment to college. Methodology/Approach: Data were collected from four universities across the United States. Participants in this study were 205 undergraduate students from 17 to 25 years old who self-enrolled in their respective institutions OOP. This study used the College Student Readiness Inventory to generate a hypothesis concerning the possible effects of an OOP experience concerning predictive and outcomes variables relative to college student commitment. Findings/Conclusions: Using SmartPLS, the main effects of the OOP indicated predictive relationships between Commitment to College and Goal Striving, Communication Skills, Social Activity, Emotional Reactivity, Study Skills, and Social Connection. Academic Self-Discipline, Academic Self-Confidence, and Self-Determination on Commitment to College. Implications: Study findings suggest specific connections between predicting college student commitment before and after an OOP.

AIMS: To verify the effectiveness of the simulation in the self-confidence of nursing students for extra-hospital cardiopulmonary resuscitation. METHODS: A quasi-experimental, before and after, single-group study, was performed with nursing undergraduate students. The sample was recruited among university students who were in the second or third year of graduation and accepted to participate in the research. The intervention protocol consisted of individual participation in a emergency simulated clinical scenario. The simulated scenario adopted consisted of cardiopulmonary resuscitation in extra-hospital cardiorespiratory arrest, using the Mini Anne Plus® low fidelity manikin. In addition to the sociodemographic variables, students' self-confidence for emergency action was analyzed, evaluated by the Self-Confidence Scale, before and after each simulation. Marginal and homogeneous Wilcoxon homogeneity tests were applied, and the accepted significance level was 5%.RESULTS: Thirteen two undergraduate students in nursing between the ages of 18 and 38 participated in the study. Statistically significant differences (p < 0.001) were observed in the answers of all the questions of the Self-confidence Scale when compared before and after the simulation. There was also a statistically significant increase (p < 0.001) in cardiological, respiratory and neurological scores after simulation.CONCLUSIONS: The simulation proved to be an effective educational strategy in increasing the self-confidence of nursing students to perform extra-hospital cardiopulmonary resuscitation.

The current paper criticizes the concept, research methodology, data analyses, and validity of the conclusions made in Hardy, Woodman, and Carrington’s (2004) article published in this journal. In their repeated-measures analysis of data from the performances of 7 golfers, they did not examine changes in performance scores on successive holes. Instead, Hardy et al. used several ANOVA models to examine how performance varied with respect to somatic and cognitive anxiety level and self-confidence interaction. By doing so, their findings produced effects which we argue to be conceptually and empirically limited. We also address problems associated with dichotomization of continuous variables, measurement errors when splitting data, eradication of random significant effects, cell sizes in segmental quadrant analysis, and correlation between somatic and cognitive anxiety. We believe these difficulties prevent any reliable conclusions and/or generalizations from being made.
