The Effect of Trainer Muscularity and Expertise on Self-Presentational Concerns, Body Image, and Performance in College Men during One-Repetition Maximum Testing

This study attempted to manipulate self-presentational efficacy to examine the effect on social anxiety, social physique anxiety, drive for muscularity, and maximal strength performance during a one-repetition maximum (1-RM) chest press and leg press test. Ninety-nine college men with a minimum of six months of previous weight training experience were randomly assigned to complete a 1-RM protocol with either a muscular male trainer described as an expert or a lean male trainer described as a novice. Participants completed measures of self-presentation and body image prior to meeting their respective trainer, and following the completion of the 1-RM tests. Although the self-presentational efficacy manipulation was not successful, the trainers were perceived significantly differently on musculature and expertise. The group with the muscular, expert trainer reported higher social anxiety and attained higher 1-RM scores for the chest and leg press. Thus, trainer characteristics can affect strength performance and self-presentational concerns in this population.

El test Bender como detector de problemas emocionales y comportamentales en niños de cuarto y quinto de primaria

Determinar si el test de Bender puede discriminar, en niños de cuarto y quinto de primaria, problemas emocionales y comportamentales y poder establecer un diagnóstico diferencial. Los objetivos específicos se agrupan en tres bloques: 1.- El Test de Bender y variables sociodemográficos. 2.- El test de Bender como prueba madurativa. 3.- El test de Bender como técnica proyectiva. Con el fin de dar respuestas a los objetivos planteados se formula una serie de hipótesis que orientan el análisis de los resultados. Esta investigación consiste en un estudio descriptivo correlacional. Se realiza mediante la aplicación del test Gestáltico Visomotor de Bender. Se trata de una investigación básicamente descriptiva y correlacional, donde se han seleccionado sujetos de diferentes edades (9-11 años) evaluados en un solo momento temporal. Las variables que se han utilizado, se han clasificado en variables sociodemográificas y psicológicas. La población la componen los alumnos de cuarto y quinto de primaria de la población de Huelva, capital y provincia. La elección de los distintos colegios se ha realizado teniendo en cuenta el nivel socioeconómico y profesional de los padres. La muestra está constituida por 722 sujetos de los cuales el 49,8 por ciento corresponde a varones y el 50,1 por ciento a mujeres, escolarizado en colegios públicos y concertados pertenecientes a Huelva capital y periferia. La selección de los instrumentos de medida se establece el criterio de que sean técnicas fiables, asequibles y fáciles de aplicar : Prueba de maduración visomotora: Test Bender. Prueba de capacidad intelectual: Test de Factor 'G' de R. B. Cattell y A. K. S. Cattell (Escala 2, Forma A). Cuestionario de Personalidad para niños EPQ-J De H. J. Eysenck y S. B. G. Eysenck. Cuestionario de autoevaluación Ansiedad estado-rasgo en niños, de C. D. Spielberg et al. Cuestionario para el profesor tutor. El test de Bender se podría emplear como screening para detectar desajustes madurativos que pueden tener como consecuencias problemas emocionales y posibles conductas antisociales, pero no es válido para detectar patologías diferenciales como la ansiedad, neuroticismo y psicoticismo. Se puede considerar esta prueba como un complemento de las técnicas psicométricas y así proporcionar, no sólo una visión analítica, sino una perspectiva más global de la persona. Sin embargo, en la utilización del test de Bender como test de personalidad se deben tener en cuenta los siguientes planteamientos: a. Aplicarlo de forma individual. b. Conveniencia de tener una pequeña entrevista con el niño. c. Es aconsejable que el evaluador tenga experiencia en el manejo de pruebas proyectivas y amplios conocimientos de psicopatología infantil. d. Así mismo, es muy importante que el evaluador tenga cierto entrenamiento y experiencia con el test de Bender. Es importante seguir investigando los índices que se asocian a conductas disruptivas y asociales, pues parece que es donde se han obtenido más relaciones y quizás en un futuro pueda ser utilizada de manera preventiva.

Effect of three exercise programs on patients with chronic obstructive pulmonary disease

We compared the effect of three different exercise programs on patients with chronic obstructive pulmonary disease including strength training at 50_80% of one-repetition maximum (1-RM) (ST; N = 11), low-intensity general training (LGT; N = 13), or combined training groups (CT; N = 11). Body composition, muscle strength, treadmill endurance test (TEnd), 6-min walk test (6MWT), Saint George's Respiratory Questionnaire (SGRQ), and baseline dyspnea (BDI) were assessed prior to and after the training programs (12 weeks). The training modalities showed similar improvements (P > 0.05) in SGRQ-total (ST = 13 ± 14%; CT = 12 ± 14%; LGT = 11 ± 10%), BDI (ST = 1.8 ± 4; CT = 1.8 ± 3; LGT = 1 ± 2), 6MWT (ST = 43 ± 51 m; CT = 48 ± 50 m; LGT = 31 ± 75 m), and TEnd (ST = 11 ± 20 min; CT = 11 ± 11 min; LGT = 7 ± 5 min). In the ST and CT groups, an additional improvement in 1-RM values was shown (P < 0.05) compared to the LGT group (ST = 10 ± 6 to 57 ± 36 kg; CT = 6 ± 2 to 38 ± 16 kg; LGT = 1 ± 2 to 16 ± 12 kg). The addition of strength training to our current training program increased muscle strength; however, it produced no additional improvement in walking endurance, dyspnea or quality of life. A simple combined training program provides benefits without increasing the duration of the training sessions.

Sorologia Anti PGL-1 e risco de ocorrência de hanseníase em área de alta endemicidade do Estado de São Paulo: quatro anos de seguimento

Os testes sorológicos para diagnóstico de hanseníase, usando o glicolipídeo-fenólico-1 (PGL-1), considerado antígeno específico do M. leprae, têm aberto algumas possibilidades de estudo do comportamento epidemiológico desta doença. Algumas questões, como tempo de latência da doença, infecção subclínica e importância do contato intra-domiciliar (contatos) no controle da endemia, puderam ser melhor analisadas usando este instrumental. Este estudo teve por objetivo verificar a existência de associação entre a situação sorológica e a ocorrência de hanseníase. Foram seguidas, durante 4 anos, 6.520 pessoas com idade igual ou superior a 5 anos, submetidas no início do seguimento ao teste sorológico Anti PGL-1, pertencentes ao universo de 7.416 habitantes da área urbana de um município paulista caracterizado por elevada endemicidade de hanseníase. Foi identificado um grupo de 590 indivíduos soropositivos (9,0 %). Foram diagnosticados, no período, 82 casos novos de hanseníase, 26 no grupo de soropositivos (441 casos novos/10.000 indivíduos) e 48 no de soronegativos (81/10.000). Entre os que não fizeram sorologia, surgiram 8 casos novos (89/10.000). Procurou-se controlar, na análise, a condição de contato, dado que a taxa de soropositividade padronizada por idade e sexo era de 9,61% no grupo de contatos e 7,65% no de não-contatos. Tomando-se os não-contatos soronegativos como o grupo de não expostos, foram calculados os riscos relativos de adoecimento no período, a partir das taxas de detecção padronizadas por idade, resultando no seguinte: os contatos ID soropositivos apresentaram a taxa de 1.704/10.000, 27 vezes maior que a dos não-expostos, igual a 63/10.000; os não-contatos soropositivos e os contatos soronegativos apresentaram taxas, respectivamente, de 274 e 198/10.000, ambas maiores que as dos não-expostos e iguais entre si. A soropositividade associou-se à elevação de 8,6 vezes do risco de hanseníase entre os contatos e de 4,4 entre os não-contatos. Na situação epidemiológica estudada, caracterizada por elevada endemicidade de hanseníase, 50% dos casos novos surgiram entre os não-contatos soronegativos, ou seja, sem fonte de infecção conhecida. Portanto, o teste anti-PGL-1 usado revela-se, na prática, de pouca aplicabilidade. Resta estudar ainda o comportamento da sorologia anti-PGL-1 em áreas de média e baixa endemicidade para que se possa tirar conclusões mais consubstanciadas sobre sua utilidade no controle da endemia. Recomenda-se o aprofundamento das pesquisas sorológicas e de outras que aprimorem o diagnóstico precoce da infecção subclínica, inclusive para detecção de formas paucibacilares, para se ampliar as possibilidades de influir no controle endêmico.

The Lactate Minimum Test protocol provides valid measures of cycle ergometer VO2 peak

Aim. The aim of the present study was to investigate the validity of the Lactate Minimum Test (LMT) for the determination of peak VO2 on a cycle ergometer and to determine the submaximal oxygen uptake (VO2) and pulmonary ventilation (VE) responses in an incremental exercise test when it is preceded by high intensity exercise (i.e., during a LMT).Methods. Ten trained male athletes (triathletes and cyclists) performed 2 exercise tests in random order on an electromagnetic cycle ergometer: 1) Control Test (CT): an incremental test with an initial work rate of 100 W, and with 25 W increments at 3-min intervals, until voluntary exhaustion; 2) LMT: an incremental test identical to the CT, except that it was preceded by 2 supramaximal bouts of 30-sec (similar to120% VO(2)peak) with a 30-sec rest to induce lactic acidosis. This test started 8 min after the induction of acidosis.Results. There was no significant difference in peak VO2 (65.6+/-7.4 ml.kg(-1).min(-1); 63.8+/-7.5 ml.kg(-1).min(-1) to CT and LMT, respectively). However, the maximal power output (POmax) reached was significantly higher in CT (300.6+/-15.7 W) than in the LMT (283.2+/-16.0 W).VO2 and VE were significantly increased at initial power outputs in LMT.Conclusion. Although the LMT alters the submaximal physiological responses during the incremental phase (greater initial metabolic cost), this protocol is valid to evaluate peak VO2, although the POmax reached is also reduced.

Electromyographic fatigue threshold of the biceps brachii muscle during dynamic contraction

The purpose of this study was to identify the Electromyographic Fatigue Threshold (EMG FT) of the biceps brachii muscle bilaterally during the elbow flexion in tests performed in different times: 30 second test, 1 minute test and fatiguing test, in concentric (CC) and eccentric (EC) phases. Nine healthy young men performed the elbow flexion with loads corresponding at 25%, 35% and 45% of the one repetition maximum (1-RM) in separate days. The results indicated that the test applied for the biceps brachii muscle during elbow flexion induced a progressive increment of EMG activity with time indicating muscle fatigue and allowed the identification of the EMG FT. The three tests presented no difference of EMG FT between CC and EC phases bilaterally.

Detection of enterotoxin and toxic shock syndrome toxin 1 genes in Staphylococcus, with emphasis on coagulase-negative staphylococci

The detection of staphylococcal enterotoxins is decisive for the confirmation of an outbreak and for the determination of the enterotoxigenicity of strains. Since the recognition of their antigenicity, a large number of serological methods for the detection of enterotoxins in food and culture media have been proposed. Since immunological methods require detectable amounts of toxin, molecular biology techniques represent important tools in the microbiology laboratory. In the present study, polymerase chain reaction (PCR) was used to identify genes responsible for the production of enterotoxins and toxic shock syndrome toxin 1 (TSST-1) in S. aureus and coagulase-negative staphylococci (CNS) isolated from patients and the results were compared with those obtained by the reverse passive latex agglutination (RPLA) assay. PCR detection of toxin genes revealed a higher percentage of toxigenic S. aureus strains (46.7%) than the RPLA method (38.3%). Analysis of the toxigenic profile of CNS strains showed that 26.7% of the isolates produced some type of toxin, and one or more toxin-specific genes were detected in 40% of the isolates. These results suggests the need for further studies in order to better characterize the pathogenic potential of CNS and indicate that attention should be paid to the toxigenic capacity of this group of microorganisms.

Influência do fortalecimento muscular no equilíbrio e qualidade de vida em indivíduos com doença de Parkinson

This study aimed to evaluate the effect of muscle strengthening in the balance, mobility and quality of life (QoL) in individuals with Parkinson's disease (PD), and to check the correlation between muscle strengthening and QoL. Nine subjects belonging to both sexes, diagnosed with PD, participated in this study. Initially, they went through an evaluation of their balance and functional mobility through the Berg Balance Scale (BBS), the ­Timed Up and Go (TUG) test, and a QoL test through the Parkinson's Disease Questionnaire (PDQ-39). The subjects also performed a test for determining the maximum load (one-repetition maximum) for the muscle groups trained. After the normality and homogeneity of the data were verified, the Student's t-test and Spearman correlation test were carried out. A significance level of p<0.05 was considered. We verified an improvement in balance (p=0.008) and QoL (p=0.013), and a negative correlation between balance and QoL (evaluation: r=-0.65 and p=0.05, revaluation: r=-0.82 and p=0.005). It was concluded that muscle strengthening was efficient in the improvement of balance and QoL in individuals with PD.

Efeito do treinamento contrarresistência e isoflavona na densidade mineral óssea em mulheres na pós-menopausa

This study aimed to investigate the independent and additive effects of counter-resistance training (RT) and soy isoflavone supplement (ISO) on bone mineral density (BMD) and bone turnover in postmenopausal women. This study used a placebo-controlled, double-blinded (soy), randomized two (ISO vs. placebo) x two (RT vs. no RT) design. Eighty sedentary postmenopausal women, aged 45-70 years, were randomly assigned to one of four groups (71 completed a 9-month intervention): RT+ISO (n=15); no RT+ISO (n=20); RT+placebo (n=18); no RT+placebo (n=18). Participants randomized to ISO received 100mg/ day/oral of soy isoflavone; and those to RT attended supervised counter-resistance training sessions at least twice a week. At baseline and 9-month, BMD was estimated by dual-energy X-ray absorptiometry (DXA). Serum levels of C-terminal cross-linked telopeptide of type I collagen (CTX), osteocalcin, and insulin-like growth factor-1 (IGF-1) were measured as bone turnover. ANOVA with time as the repeated measure and test t were used in the statistical analysis. After 9 months of intervention, neither ISO nor RT alone affected BMD at any site or levels of CTX, osteocalcin, and IGF-1 (p>0.05). ISO and RT had no additive effects on BMD and bone turnover. RT groups showed significantly increased muscle strength (+ 35.2%) (p=0.02). We found no additive effects of resistance training and soy isoflavone on bone mineral density or bone turnover in postmenopausal women after 9-months.
