Frailty consensus : a call to action
No full textFrailty is a clinical state in which there is an increase in an individual's vulnerability for developing increased dependency and/or mortality when exposed to a stressor. Frailty can occur as the result of a range of diseases and medical conditions. A consensus group consisting of delegates from 6 major international, European, and US societies created 4 major consensus points on a specific form of frailty: physical frailty. 1. Physical frailty is an important medical syndrome. The group defined physical frailty as "a medical syndrome with multiple causes and contributors that is characterized by diminished strength, endurance, and reduced physiologic function that increases an individual's vulnerability for developing increased dependency and/or death." 2. Physical frailty can potentially be prevented or treated with specific modalities, such as exercise, protein-calorie supplementation, vitamin D, and reduction of polypharmacy. 3. Simple, rapid screening tests have been developed and validated, such as the simple FRAIL scale, to allow physicians to objectively recognize frail persons. 4. For the purposes of optimally managing individuals with physical frailty, all persons older than 70 years and all individuals with significant weight loss (>5%) due to chronic disease should be screened for frailty
Secular Trends In Age At Menarche In Relation To Body Mass Index [tendência Secular Da Idade Da Menarca Avaliada Em Relação Ao índice De Massa Corporal]
No full textObjective: To evaluate the secular trend of menarche according to body mass index (BMI). Subjects and methods: Six hundred and eighty five girls (7-18 years) assessed in 2001 were compared with 750 evaluated in 2010. They were grouped by BMI Z-score: (thin + normal) and (overweight + obese). Menarche was reported by status quo and age at menarche estimated by a logit model. We used the Qui-square test, Mann-Whitney test, and Logistic Regression, at a 5% significance level. Results: Menarche advanced 3.24 months. There was an increase in obesity, and a decrease of the prevalence of normal girls. Menarche was anticipated by 1.44 month in the thin + normal group and by 5.76 months in the overweight + obese group. There was no interaction between the effects determined by the evaluated period and nutritional diagnosis. Conclusions: Although both the period and BMI influence the menarche, one cannot attribute this advance only to changes in the nutritional profile of the sample. Other factors that were not tested may also contribute to this finding.563195200Euling, S.Y., Herman-Giddens, M.E., Lee, P.A., Selevan, S.G., Juul, A., Sorensen, T.I., Examination of US puberty-timing data from 1940 to 1994 for secular trends: Panel findings (2008) Pediatrics., 121 (SUPPL. 3), pp. S172-S191Kaplowitz, P.B., Link between body fat and the timing of puberty (2008) Pediatrics., 121 (SUPPL. 3), pp. S208-S217Morris, D.H., Jones, M.E., Schoemaker, M.J., Ashworth, A., Swerdlow, A.J., Secular trends in age at menarche in women in UK born 1908-93: Results from the Breakthrough Generations Study (2011) Paediatr Perinat Epidemiol, 25 (4), pp. 394-400Biro, F.M., Khoury, P., Morrison, J.A., Influence of obesity on timing of puberty (2006) Int J Androl., 29 (1), pp. 272-277Nour, N.N., Obesity in resource-poor nations (2010) Rev Obstet Gynecol., 3 (4), pp. 180-184Prentice, A.M., The emerging epidemic of obesity in developing countries (2006) Int J Epidemiol., 35 (1), pp. 93-99Solorzano, C.M.B., McCartney, C.R., Obesity and the puberal transition in girls and boys (2010) Reproduction., 140 (3), pp. 399-410Wang, Y., Is obesity associated with early maturation?

Obesidade e maturação sexual precoce: um estudo transversal com escolares em Florianópolis - SC
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Nutrição.O objetivo deste estudo foi investigar a associação entre maturação sexual precoce e obesidade em meninos e meninas de 10 a 14 anos de Florianópolis. Participaram do estudo 629 escolares entre 10 e 14 anos (277 meninos e 352 meninas), obtidos de duas escolas públicas e duas escolas privadas da região central do município. Foi utilizado o índice de massa corporal (IMC) para determinação de sobrepeso e obesidade, com os pontos de corte e os valores de LMS por sexo e idade de Conde & Monteiro (2006). Os valores de LMS de peso e estatura foram obtidos do Centers of Disease Control (CDC 2000). Os valores de LMS foram utilizados para obtenção do Z escore. A maturação sexual foi avaliada de acordo com os estágios de Tanner (1962). Os indivíduos foram agrupados por tercis da idade de acordo com cada estágio e sexo. O 1º tercil foi considerado como maturação sexual precoce; e o 2º tercil, como grupo de referência. As meninas com maturação sexual precoce são mais pesadas, altas e possuem maiores valores de IMC por idade, bem como maior prevalência de sobrepeso incluindo obesidade do que meninas do grupo de referência. Já os meninos com maturação sexual precoce são mais altos por idade; contudo não apresentam maior prevalência de sobrepeso incluindo obesidade. Os achados deste estudo corroboram aqueles da literatura que afirmam que meninas com maturação sexual precoce têm maiores prevalências de obesidade do que meninas sem maturação sexual precoce. Em relação aos meninos, o presente estudo não encontrou associação entre maturação sexual precoce e obesidade
Força muscular e variáveis sociodemográficas, estilo de vida e condições de saúde em idosos de uma comunidade do sul do Brasil
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2013.Objetivo: Analisar a associacao entre forca muscular, variaveis sociodemograficas, estilo de vida e condicoes de saude em idosos de uma comunidade do sul do Brasil, de acordo com o sexo. Metodos: Trata-se de estudo epidemiologico transversal, de base domiciliar, que abrangeu 477 idosos (.60 anos) por meio de amostra probabilistica, do municipio de Antonio Carlos/SC. A forca muscular foi analisada por meio dos testes de forca de preensao manual (FPM) (dinamometro) e forca muscular de membros inferiores (FMMI) (#glevantar e sentar de uma cadeira#h). As variaveis explanatorias foram idade; saber ler e escrever (sim/nao); arranjo familiar (sozinho/acompanhado); tipo de trabalho ao longo da vida (agricultura/outros); condicao de trabalho (sim/nao), tabagismo (nunca fumou/ex-fumante e fumante atual); tempo sentado (.4/ 4-5/ .6 horas/dia); numero de morbidades (0-2/3+); sofrer quedas (sim/nao); estado cognitivo (alterado/normal). A regressao de Poisson (Razao de prevalencia [RP] e IC 95% [intervalo de confianca]) foi usada para analisar os dados. Resultados: Foram analisados 270 mulheres (73,2 #}8,82 anos) e 207 homens (73,3 #}8,96 anos). A frequencia de FPM inadequada e FMMI inadequada foi de 18,8% (IC95%:13,8-23,7) 29,8% (IC95%:23,9-35,6) no sexo feminino, respectivamente. Em ambos os testes, a forca inadequada foi associada a idade, a nao trabalhar e ao estado cognitivo alterado; e a sofrer quedas, no teste de FMMI. Nos homens, a FPM inadequada foi de 19,0% (IC95%: 13,3-24,8) e a FMMI inadequada foi de 25,3% (IC95%: 18,9-31,7) e foram associadas a idade, a nao saber ler e escrever, a relatar 3 ou mais morbidades. A FMMI inadequada tambem foi associada a trabalhar na agricultura ao longo da vida, a nao trabalhar, a nunca fumar e ao estado cognitivo alterado. Conclusao: Os fatores associados a forca muscular sao especificos ao teste e ao sexo. Os fatores associados a FPM sao idade, nao trabalhar e o estado cognitivo; e sofrer quedas com a FMMI, nas mulheres. Nos homens, a idade, nao saber ler e escrever, relatar 3 ou mais morbidades foram associados a FPM e FMMI inadequadas; e trabalhar na agricultura ao longo da vida, nao trabalhar, nunca fumar e estado cognitivo alterado foram associados a FMMI inadequada. Visto que estas medidas tem estreita relacao com a saude dos individuos e se configuram como metodos simples, poderiam ser inseridos na pratica da Estrategia Saude da Familia.Objective: To verify the association between muscular strength, sociodemographic variables, lifestyle, and health conditions in elderly community in the South of Brazil, by sex. Methods: A cross-sectional epidemiological study, with population and household basis, made with 477 elderly persons (60 years and older) by probabilistic sample, residing in the municipality of Antonio Carlos. The muscular strength was verified by tests of handgrip strength (HGS) (dynamometer) and lower limb muscular strength/resistance (LLMS) (#gchair stand#h). The variables analyzed were age, knows how to read and write (yes/no), occupation throughout life (agriculture/other professions), family arrangement (lives alone/lives accompanied), currently working (yes/no), smoking (smoker; former smoker/never smoked), sitting time (. 4; 4-5; .6 hours/day), number of morbidities (0 to 2/3 or more), falls in the last year (no/yes), and cognitive state (normal/altered). The Poisson#fs regression (Prevalence ratio [PR] and 95% CI [confidence interval]) was used as measure of association. Results: We analyzed 270 women (73.2 #} 8.82 years) and 207 men (73.3 #} 8.96 years). The proportion of inadequate HGS and LLMS was 18.8% (95%CI: 13.8-23.7) and 29.8% (95%CI: 23.9-35.6) in female, respectively. In two tests, the inadequate strength was associated with age, the condition of not working, and the altered cognitive state. Furthermore, having suffered fall during the last year was associated with inadequate strength in LLMS test. In men, inadequate HGS was 19.0% (IC95%: 13.3-24.8) and LLMS was 25.3% (IC95%: 18.9-31.7) and was associated with age, no knows how to read and write, and 3 or more morbidities. The inadequate LLMS was also associated with work in agriculture throughout life, no currently working, never smoked and cognitive state altered. Conclusion: Factors associated with muscle strength are specific to the test. Factors associated with HGS are age, no work and cognitive state; on the other hand having suffered fall was associated with inadequate strength in LLMS test. In men, age, no knows how to read and write, 3 or more morbidities was associated with inadequate HGS and LLMS; work in agriculture throughout life, no currently working, never smoked and cognitive state altered was associated with inadequate strength in LLMS test. Strength tests are simple to apply and have a close relationship with the health of individuals. So, could be inserted in the practice of Family Health Strategy
Anthropometric And Motor Performance Characteristics Of Futsal Athletes In Different Categories [características Antropométricas E De Desempenho Motor De Atletas De Futsal Em Diferentes Categorias]
No full textThe objective of this study was to analyze the anthropometric characteristics of young futsal (five-a-side soccer) players and to make comparisons between different competitive categories. To this end, 232 male athletes aged 8 to 18 years, playing in the following categories: under-9 (8-9 years; n = 56), under-11 (10-11 years; n = 62), under-13 (12-13 years; n = 36), under-15 (14-15 years; n = 29), under-17 (16-17 years; n = 35) and under-19 (18 years; n = 14), underwent anthropometric measurement to obtain body mass (MB), height, middle-upper arm circumference and skin fold thicknesses (triceps and subscapular). Based on these measurements, body mass index (BMI), sum of skin folds thickness (ΣSF), relative body fat (% fat) and muscular area of the arm (MAB) were all calculated. Motor performance was analyzed based on the results of the following tests: modified 1-minute abdominal (ABD), horizontal impulse (HI), 9/12 minute walk/run (9/12 min) and medicine ball throw (MB). Categories were compared using one-way ANOVA, followed by Scheffé's post hoc test when p<0.05. Canonical discriminant functions were used to analyze groupings across different ages in terms of specific characteristics (BMI, ΣSF, % fat; ABD, HI and MB). The MB results increased significantly in all categories, reaching a plateau in the under-17 and under- 19 categories. The under-9 and under-11 categories were different from all others in terms of MAB and the under-13s and under-15s were different from the under-17s and under-19s for the same measure. The % fat reduced as age increased, differing significantly form the under-11 category onwards. Test results for ABD and MB were significantly lower in the under-9 and under-11 categories than in all others. Under-15, under-17 and under-19 categories had better HI and 9/12 min results than the remaining categories. It was concluded that young futsal players can be classified as within the normal profile of the population with the same age, both in terms of anthropometric characteristics and motor performance.93297302Santana, W.C., (2006) Contextualização histórica do futsal, , http://www.pedagogiadofutsal.com.br/historia.asp, Disponível em, [2007 maio 10](1369) Futsal and beach soccer enjoying rising interest, FIFA research shows, , http://www.fifa.com/en/media/index/0122047,00.html, FIFA, 2006Disponível em, [2007 maio 10]Santana, W.C., Reis, H.H.B., Ribeiro, D.A., A iniciação de jogadores de futsal com participação na seleção brasileira (2006) Lecturas Educación Física y Deportes [periódico on line], p. 96. , http://www.efdeportes.com/efd96/futsal.htm, Disponível em, [2007 maio 10]Costa, L.P., (2005) Atlas do esporte no Brasil: Atlas of Sports in Brazil, , São Paulo: ShapeHallal, P.C., Bertoldi, A.D., Gonçalves, H., Victora, C.G., Prevalência de sedentarismo e fatores associados em adolescentes de 10-12 anos de idade (2006) Cad Saúde Pública., 22 (6), pp. 1277-1287Arena, S.S., Bohme, M.T.S., Programas de iniciação e especialização esportiva na Grande São Paulo (2000) Rev Paul Educ Fís, 14 (2), pp. 184-195Silva, F.M., Fernandes, L., Celani, F.O., Desporto de crianças e jovens-um estudo sobre as idades de iniciação (2001) Rev Port Ciênc Desp, 1 (2), pp. 45-55Ré, A.H.N., Teixeira, C.P., Massa, M., Bohme, M.T.S., Interferência de características antropométricas e de aptidão física na identificação de talentos no futsal (2003) Rev Bras Ciên Mov, 11 (4), pp. 51-56Gordon, C.C., Chumlea, W.C., Roche, A.F., Stature, recumbent length, and weight (1988) Anthropometric standardization reference manual, pp. 3-8. , In: Lohman TG, Roche AF, Martorell R, editors, Champaign: Human Kinetics BooksHarrison, G.G., Buskirk, E.R., Carter, L.J.E., Johston, F.E., Lohman, T.G., Pollock, M.L., Roche, A.F., Wilmore, J.H., Skinfold thickness and measurement technique (1988) Anthropometric standardization reference manual, pp. 55-70. , In: Lohman TG, Roche AF, Martorell R, editores, Champaign, Illinois: Human Kinetics BooksSlaughter, M.H., Lohman, T.G., Boileau, R.A., Horswill, C.A., Stilman, R.J., Van Loan, M.D., Skinfold equations for estimation of body fatness in children and youth (1988) Hum Biol, 60 (5), pp. 709-723Frisancho, A.R., New standards of weight and body composition by frame size and height for assessment of nutritional status of adults and the elderly (1984) Am J Clin Nutr, 40 (4), pp. 808-819Hair, J.F., Black, B., Babin, B., Anderson, R.E., Tatham, R.L., (2005) Multivariate data analysis, , 6. ed.

Anthropometric And Motor Performance Profile Of Elite Futsal Athletes [perfil Antropométrico E De Desempenho Motor De Atletas Paranaenses De Futsal De Elite]
No full textThe purpose of the present study was to identify the anthropometric and motor performance profile of futsal (indoor soccer) athletes in the second and third-placed teams in the Parana state championships (Brazil). Anthropometric (body mass, stature and skinfolds thickness) and motor performance (modified abdominal test, shuttle run, race of 30 m and 40 s) measures were obtained from twenty-seven male athletes (24.7 ± 6.4 years; 73.6 ± 7.6 kg; 174.8 ± 6.6 cm). For data analysis, athletes were grouped according to game positions. ANOVA one-way was used for comparisons between different positions, followed by Scheffé's post hoc test, with p < 0.05. Significant differences were detected in body mass (midfielder < goalkeeper, p < 0.01), stature (midfielder < forward and goalkeeper, p < 0.01) and lean body mass (midfielder < goalkeeper, p < 0.01). No significant differences in motor performance were detected between the athletes studied. The results of this study show that futsal athletes playing in different positions exhibit similar anthropometric and motor performance, in the majority of variables.1017680Altimari, L.R., Okano, A.H., Coelho, C.F., Cyrino, E.S., Efeitos do treinamento de futsal sobre o desempenho motor em atividades predominantemente aeróbias e anaeróbias (1999) Trein Desp, 4, pp. 23-28Cyrino, E.S., Altimari, L.R., Okano, A.H., Coelho, C.F., Efeitos do treinamento de futsal sobre a composição corporal e o desempenho motor de jovens atletas (2002) Rev Bras Ciên Mov, 10, pp. 41-46Freitas, L.A.G., Altimari, L.R., Estudo somatotipológico de atletas de futebol de salão da categoria fraldinha e prémirim (1999) Trein Desp, 4, pp. 29-34Lima, A.M.J., Silva, D.V.G., Souza, A.O.S., Correlação entre as medidas direta e indireta do VO2max em atletas de futsal (2005) Rev Bras Med Esporte, 11 (3), pp. 164-166Queiroga, M.R., Ferreira, S.A., Romanzini, M., Per fil antropométrico de atletas de futsal feminino de alto nível competitivo conforme a função tática desempenhada no jogo (2005) Rev Bras Cineantropom Desempenho Hum, 7 (1), pp. 30-34Goulart, L.F., Dias, R.M.R., Altimari, L.R., Força isocinética de jogadores de futebol categoria sub-20: Comparação entre diferentes posições de jogo (2007) Rev Bras Cineantropom Desempenho Hum, 9 (2), pp. 165-169Wisloff, U., Helgerud, J., Hoff, J., Strength and endurance of elite soc c er players (1998) Med Sci Spor ts E xerc, 30 (3), pp. 462-467Bicalho, E.L.C., Paula, A., Cotta, D.O., (2007) Estudo da diferença do perfil físico de jogadores de futsal por posicionamento em quadra que participaram do campeonato Ipatinguense., , http://www.efdeportes.com/efd104/futsal.htm, Lecturas [revista digital].

Behavior Of The Muscle Strength And Arm Muscle Area During 24 Weeks Of Weight Training [comportamento Da Força Muscular E Da área Muscular Do Braço Durante 24 Semanas De Treinamento Com Pesos]
No full textThe purpose of this study was to analyze the behavior of muscle strength and arm muscle area (AMA) over 24 weeks of weight training (WT) as well as to establish possible associations between these variables. The sample was composed of 18 men aged between 18 and 30 years. Measurements of relaxed arm circumference and triceps skinfold measurement were used for the calculation. Muscle strength was assessed using the one-repetition maximum test (1-RM) on the arm curl exercise. The WT protocol lasted 24 weeks, divided into 3 stages (F1, F2, and F3) of 8 weeks each. It is important to emphasize that every measurement was made before, during and after the end of the WT period. Analysis of variance (ANOVA) for repeated measures followed by the Tukey post hoc (P < 0.05) was used to the compare the indicators of muscle strength and muscle hypertrophy. Pearson's correlation coefficient was used to verify possible association between muscle strength and AMA. Muscle strength and AMA increased continuously throughout the whole period except for the initial period (F1). Therefore, it is concluded that the initial phase of training, neuromuscular adaptation, seems to have been the turning point for increase in muscle strength. After that, the hypertrophy process appears to gradually become the essential factor for increase in muscle strength.104379385Position Stand: Progression models in resistance training for healthy adults (2002) Med Sci Sports Exerc, 34 (2), pp. 364-380. , American College of Sports MedicineBernhardt, D.T., Gomez, J., Johnson, M.D., Martin, T.J., Rowland, T.W., Small, E., Strength training by children and adolescents (2001) Pediatrics., 107 (6), pp. 1470-1472Kraemer, W.J., Ratamess, N.A., Fundamental of resistance training: Progression and exercise prescription (2004) Med Sci Sports Exerc, 36 (1), pp. 674-688Jones, D.A., Rutherford, O.M., Parker, D.F., Physiological changes in skeletal muscle as a result of strength training (1989) Q J Exp Physiol, 74 (3), pp. 233-256Moritani, T., Time course of adaptations during strength and power training (1992) The encyclopedia of sports medicine: Strength and power in sport., pp. 266-278. , In: Komi PV, editor.

Association Between The Electromyographic Fatigue Threshold And Ventilatory Threshold
No full textThe objective of this study is to verify the coincidence between the occurrence of the electromyographic fatigue threshold (EMGth) and the ventilatory threshold (Vth) in an incremental test in the cyclosimulator, as well as to compare the calculation of the RMS from the EMG signal using different time windows. Thirteen male cyclists (73.7 ± 12.4 kg and 174.3 ± 6.2 cm) performed a ramp incremental test (TI) in a cyclosimulator until voluntary exhaustion. Before the start of each TI subjects had the active bipolar electrodes placed over the superficial muscles of the quadriceps femoris (QF) of the right leg: rectus femoris (RF), vastus medialis (VM) and vastus lateralis (VL). The paired student's t test, pearson's correlation coefficient and the analysis method described by Bland and Altman for the determination of the concordance level were used for statistical analysis. The significance level adopted was P < 0.05. Although no significant differences were found between Vth and the EMG th calculated from windows of 2, 5, 10, 30 and 60 seconds in the studied muscles, it is suggested that the EMGth values determined from the calculation of the RMS curve with windows of 5 and 10 seconds seem to be more appropriate for the calculation of the RMS curve and determination of EMGth from visual inspection.496-7305310Basmajian, J.V., DeLuca, C.J., (1985) Muscles Alive: Their Functions Revealed by Electromyography, , Williams & WilkinsBland, J.M., Altman, D.G., Statistical methods for assessing agreement between two methods of clinical measurement (1986) Lancet, 1, pp. 307-310(2006) Encyclopedia of Medical Devices and Instrumentation, pp. 98-109. , DELUCA, C.J.: Electromyography.

A influência das características anatomo-físicas no aparecimento das lesões por esforços repetitivos em uma linha de produção
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção.O estudo teve como objetivo investigar a influência dos fatores individuais como as medidas dos segmentos corpóreos, alturas, circunferências, comprimentos, composição corporal, tempo de trabalho na função, idade e incidência por sexo, dos trabalhadores em linha uma de produção, numa fábrica de componentes para refrigeração na cidade de Joinville Santa Catarina, que poderiam contribuir para o aparecimento de LER/DORT. A amostra foi composta por 73 trabalhadores, 36 homens e 37 mulheres, 100 % da linha de produção. Os resultados foram analisados utilizando-se medidas de posição e dispersão descritiva, o teste t de Student, com intervalo de confiança de 95 %, análise de correlação pelo coeficiente de Pearson e percentil. Observou-se que 21,9 % da população referiram dores, 12,3 % na região do ombro, 6,8 % na região do punho, 2,7 % na região da mão e 1,3 % na região do cotovelo. Verificou-se diferença entre as médias dos segmentos corporais nos portadores e não portadores de LER/DORT. Para análise das significâncias entre as médias das variáveis utilizou-se a análise de variância e teste "t". A análise revelou que houve uma diferença significativa entre as médias das duas amostras. Para o estudo do tempo de serviço na incidência de LER/DORT, utilizou-se a correlação de Pearson obtendo o nível de 71,26 % associações entre as duas variáveis portanto, pode-se dizer que quanto maior o tempo de serviço e idade, maior a incidência de LER/DORT. Aplicando o mesmo método estatístico para a correlação entre idade e incidência de LER/DORT obteve-se um índice de 93,47 %, o que indica que quando a faixa de idade se eleva também aumenta as incidências de LER/DORT. Na análise da incidência de LER/DORT por sexo observou-se que o número de portadoras do sexo feminino é relativamente maior, 35% para o sexo feminino e 08 % para o sexo masculino
