ESTUDO DA FREQÜÊNCIA CARDÍACA, PRESSÃO ARTERIAL E DUPLO-PRODUTO EM DIFERENTES NÚMEROS DE SÉRIES DURANTE EXERCÍCIOS RESISTIDOS

Resumo: Esta pesquisa observou a freqüência cardíaca (FC), a pressão arterial sistólica (PAS) e o duplo-produto (DP) durante exercícios resistidos (ER), em função da variação do número de séries (NS). Foi adotado como exercício a extensão simultânea de joelhos na cadeira extensora, realizado em 10 RM. Fizeram parte da amostra 10 indivíduos do sexo masculino (22 À 4 anos), com experiência mínima de 6 meses em ER. No período da manhã foi feito o teste de 10 RM, e a tarde realizaram-se as 3 séries de 10 RM, respeitando o intervalo de 2 minutos entre as séries. As variáveis foram registradas entre as duas últimas repetições de cada série. Compararam-se as respostas de FC, PAS e DP por meio de ANOVA para medidas repetidas, seguida de verificação post-hoc de Tukey (

Relationship among physical activity level, mood and anxiety states and Quality of Life in Physical Education students.

Background: Physical activity level (PAL) is known to play an important role in reducing risk factors associated with sedentarism, in addition to improving the mental health and health-related quality of life (HRQL). Objective: Investigate the relationship of PAL and their domains with HRQL, mood state (MS) and anxiety. Method: 140 Physical Education students (23.6 ± 3.7 years) were evaluated. The Baecke Habitual Physical Activity and Quality of Life (QOL-36) questionnaires, State-Trait Anxiety Inventories (STAI-S and STAI-T) and Profile of Mood States (POMS) scale were used to investigate PAL, HRQL and mental health indicators. Pearson’s correlation coefficient examined the association between PAL and both mental health and HRQL parameters. Results: There was a correlation between state anxiety and both the domain leisure-time physical activity (LTPA) (p = 0.013) and total PAL score (p = 0.010). In relation to MS, a negative correlation was found between LTPA and total mood disorder (TMD) (p = 0.004). However, there were positive correlations between the vigor subscale and both LTPA (p=0.001) and total PAL (p=0.019). With respect to HRQL, analysis of the relationship between LTPA and total PAL demonstrated positive coefficients with the physical component summary (PCS) (p=0.000; p = 0.005), mental component summary (MCS) (p = 0.000; p = 0.006) and total HRQL (p = 0.000; p = 0.003). Conclusion: The findings suggest that the rise in LTPA was related to an increase in HRQL and MS. However, PAL was positively related to anxiety

Association Between Body Image and Mental Health in Adolescents: A Social Issue

The construct of esthetic beauty is culturally and socially determined and widely disseminated by the media. The body image dissatisfaction (BID) is considered a public health problem, it is an important risk factor for disorders related to mental health, which is highly prevalent in adolescents and has an impact on social behavior. We aimed to evaluate the possible association between BID and the mental health aspects of depression and risk of eating disorders and identify the prevalence in adolescent boys and girls. The sample consisted of 308 adolescent students: 167 girls (54.2%) and 141 boys (45.8%). BID was identified by the silhouette scale. The Childhood Depression Scale (CDS) and Eating Attitudes Test (EAT-26) were used to assess MH. The chi-squared contingency test showed an association between body image and mental health variables in both sexes. Results: 70.1% of the girls and 76.6% of the boys exhibited BID. The girls demonstrated a significant association between body image and depressive symptoms (X(1) = 8.523; p = 0.004) and the risk of ED (X(1) = 14.281; p = 0.000). However, the boys exhibited no interactions between body image and mental health-related factors. Although BID was high in adolescents of both sexes, it may be a marker for depression and eating disorders in girls.A construção da beleza estética é cultural e socialmente determinada e amplamente divulgada pela mídia. A insatisfação com a imagem corporal (BID), considerada um problema de saúde pública, é um importante fator de risco para transtornos relacionados à saúde mental que apresenta alta prevalência em adolescentes e impacta sobre o comportamento social. Objetivamos avaliar a possível associação entre BID e os aspectos de saúde mental da depressão e risco de transtornos alimentares e identificar a prevalência em meninos e meninas adolescentes. Método: A amostra foi composta por 308 adolescentes escolares: 167 meninas (54,2%) e 141 meninos (45,8%). O BID foi identificado pela escala de silhueta. A Escala de Depressão na Infância (CDS) e o Teste de Atitudes Alimentares (EAT-26) foram utilizados para avaliar a HM. O teste de contingência qui-quadrado mostrou associação entre a imagem corporal e as variáveis de saúde mental em ambos os sexos. Resultados: 70,1% das meninas e 76,6% dos meninos apresentaram BID. As meninas demonstraram associação significativa entre imagem corporal e sintomas depressivos (X(1) = 8,523; p = 0,004) e risco de TA (X(1) = 14,281; p = 0,000). No entanto, os meninos não exibiram interações entre a imagem corporal e os fatores relacionados à saúde mental. Conclusão: Embora o BID tenha sido elevado em adolescentes de ambos os sexos, pode ser um marcador de depressão e transtornos alimentares em meninas

Laboratório de Biociências da Motricidade Humana. Rio de Janeiro, RJ, Brasil.O objetivo do presente estudo foi avaliar a força muscular e os níveis séricos basais de testosterona e ureia em atletas de futebol. Vinte e quatro jogadores de futebol, em período pré-competitivo, tiveram amostra de sangue coletada para análise da concentração de testosterona e ureia. Em seguida, realizaram os testes de 1RM para o exercício supino horizontal e agachamento. Após a coleta de dados, foram divididos de forma aleatória em dois grupos que foram submetidos a programas de periodização ondulatória (G1) e não periodizado (G2) por 12 semanas. A ANOVA de medidas repetidas mostrou que houve aumento na concentração de testosterona sérica no G1 (Δ = 3,70ng/dl; p = 0,0001) e no G2 (Δ =1,81ng/dl; p =0,035) e redução nos níveis de ureia apenas no G1 (Δ = - 3,08mg%; p = 0,0001). O G1 mostrou maiores níveis de testosterona (Δ = 2,13ng/dl; p = 0,009) e menores de ureia (Δ = -1,36mg%; p = 0,026) no pós-teste quando comparado ao G2. Os testes de 1RM não apresentaram diferenças significativas. A periodização ondulatória da força no treinamento para jogadores de futebol demonstrou ser mais eficaz que o treinamento não periodizado para promover o aumento dos níveis séricos de testosterona e redução dos níveis de ureia.The aim of this study is to evaluate the muscle strength and basal serum testosterone and urea levels in soccer athletes. Twenty-four soccer players in pre-competitive period had a blood sample collected to have testosterone and urea concentrations analyzed. Subsequently, 1RM tests were applied to the bench press and squat exercises. After data collection, the athletes were randomly divided in two groups submitted to: non-linear periodization program (G1) and non-periodized program (G2), both for 12 weeks. ANOVA for repeated measures showed increase in serum testosterone concentration in G1 (Δ = 3.70 ng/dl; p = 0.0001) and in G2 (Δ = 1.81 ng/dl; p = 0.035) and reduction in urea levels only in G1 (Δ = -3.08mg%; p = 0.0001). G1 presented higher levels of testosterone (Δ = 2.13 ng/dl; p = 0.009) and lower levels of urea (Δ = -1.36mg%; p = 0.026) in the post-test when compared to G2. 1RM tests did not show significant differences. The non-linear training in soccer players was more effective than the non-periodized training in promoting increase in serum testosterone levels and reduction in urea levels

Relationship Among Body Image, Anthropometric Parameters and Mental Health in Physical Education Students

Background The prevalence of body image dissatisfaction (BID) is currently high. Given that psychological well-being is associated with the body measurements imposed by esthetic standards, BID is an important risk factor for mental disorders. Objective Identify the prevalence of BID, and compare anthropometric and mental health parameters between individuals satisfied and dissatisfied with their body image. Method A total of 140 university students completed the silhouette scale to screen for BID. Anthropometric measures, body mass index (BMI), waist circumference (WC) and body fat percentage (BFP) were used. To investigate mental health, The State-Trait Anxiety Inventories (STAI-S and STAI-T), Profile of Mood States (POMS) scale and Quality of Life (QOL-36) questionnaire were used to investigate mental health. The Student’s t-test was applied to compare anthropometric and mental health parameters. Results 67.1% of university students exhibited BID. There was a significant difference (p = 0.041) in BF and WC (p = 0.048) between dissatisfied and satisfied individuals. With respect to mood states, significant differences were observed for anger (p = 0.014), depression (p = 0.011), hostility (p = 0.006), fatigue (p = 0.013), mental confusion (p = 0.021) and total mood disturbance (TMD) (p = 0.001). The mental aspect of QOL was significantly higher (p = 0.001) in satisfied university students compared to their dissatisfied counterparts. Conclusion BID was high and it seems to be influenced by anthropometric measures related to the amount and distribution of body fat. This dissatisfaction may have a negative effect on the quality of life and mood state of young adults.info:eu-repo/semantics/publishedVersio
