RESUMEN
Objetivo: Investigar los efectos de las diferentes órdenes de ejecución de entrenamiento concurrente (EC) sobre las concentraciones séricas de leptina y zinc en adultos practicantes de ejercicio físico. Método: 10 sujetos (27,1 ± 4,8 años, IMC 25,49 ± 2,65) fueron sometidos a diferentes sesiones: sesión de control (SC), entrenamiento concurrente 1 (EC1) y entrenamiento concurrente2 (EC2) con un intervalo de cinco días entre cada uno. Se recogieron muestras de sangre para el análisis de leptina y zinc. La sesión EC1 consistió en ciclismo interior (ciclismo indoor) seguido de entrenamiento con pesas. El entrenamiento EC2 estaba compuesto por los mismos ejercicios con el orden invertido de ejecución: gimnasio y ciclismo indoor después. En la SC los individuos no realizan ejercicio físico. Al final de cada período de sesiones se reunió al grupo para recoger muestras de sangre que permitan comprobar los niveles de estas variables. Se utilizó la prueba de Shapiro-Wilk, Two-way ANOVA y el test post-hoc de Tukey. Resultados: Se observó una reducción significativa en las concentraciones de leptina después de TC1 (Δ = -16,04%, p =0.05) y TC2 (Δ = -8.54%, p = 0.02), con una reducción significativa después de SC diferencia (Δ = -4.29%, p = 0.11). En cuanto al zinc, no había cambios significativos en los niveles de la variable después de las sesiones TC1 y TC, con una reducción no significativa después de SC (Δ% = 8.45; p = 0.07). Conclusiones: El EC provocó una reducción de la leptina, independientemente de su orden de ejecución; sin embargo, estas reducciones no fueron acompañadas de cambios significativos en el estado de zinc de las personas (AU)
Aim: To investigate the effects of distinct perform orders of concurrent training on serum leptin and zinc concentrations of adults practitioners of physical exercise. Methods: 10 subjects (27,1 ± 4,8 years old, BMI 25,49 ±2,65) were undergone to distinct sessions: control session(CS) concurrent training 1 (CT1) and concurrent training 2 (CT2) with five days of rest between each session. Leptin and zinc blood samples were collected. CT1 session was characterized by indoor cycle followed by resistance traning. CT2 session was composed by the same exercises, however, the perform order was inverted: resistance exercise followed by indoor cycle. In CS session the subjects did not performed physical exercises. At the end of each session, new blood samples were assed to verification the levels of the same variables. Were used Shapiro-Wilk test, Two-way ANOVA and Tukey Post-Hoc test. Results: There was significative reduction on leptin concentrations after CT1 (Δ% = -16,04; p = 0.05) and after CT2 (Δ = -8.54%, p = 0.02), with reduction after SC without statistic significance (Δ% = -4,29; p= 0.11). In relation to zinc, there was no significant changes in the variable levels after TC1 and TC2, with s reduction without significance only after SC (Δ% = 8.45; p = 0.07). Conclusions: CT promoted reductions on serum leptin concentration independently of the perform order, however, such reductions were not followed by significant changes in zinc levels of the subjects (AU)

O objetivo deste estudo foi analisar o efeito do método da Reeducação Postural Global (RPG) em escolares com diagnóstico de escoliose torácica não estrutural (ETNE). Os escolares com indicativo de ETNE ao exame postural e teste de Adams negativo foram encaminhados ao exame radiográfico para comprovação diagnóstica. Foram selecionados 20 participantes (11 meninos e 9 meninas, com 10±3 anos), divididos randomicamente em dois grupos homogêneos: o que realizou o RPG (GRPG) durante 12 semanas com duração de 25 a 30 minutos cada sessão, de acordo com o que aguentou permanecer na postura; e o grupo controle (GC), sem intervenção. Após três meses, os dois grupos repetiram a avaliação postural e o exame radiográfico. Para avaliação das estatísticas, foi utilizada análise de variância (ANOVA) univariada, com medidas repetidas, seguida do Post Hoc de Tukey para identificar as possíveis diferenças intra e intergrupos. O valor de α foi de 0,05. O GRPG apresentou redução significativa no ângulo de Cobb na comparação intragrupo (Δ%=-35,100; p=0,009), mas o GC não (Δ%=9,520; p=0,789). Pode-se concluir que escolares submetidos ao método da RPG apresentaram melhora do quadro de escoliose torácica não estrutural.
The aim of this study was to analyze the effect of Global Reeducation Postural (RPG) method in scholars diagnosed with thoracic nonstructural scoliosis (ETNE). Scholars with indicative of ETNE to postural exam and Adams test negative were directed to radiographic exam to diagnostic. Twenty participants were selected (11 boys and 9 girls, 10±3 years old) and randomly divided in two homogeneous groups: group treated by RPG (GRPG) and control group (CG). The GRPG was submitted a RPG treatment during 12 weeks in sessions from 25 to 30 minutes in agreement with each student tolerance at posture. The CG didn't suffer intervention. After three months, both groups repeated the postural and radiographic exam. For statistics, it was used ANOVA univariated with repeated measures, followed by Tukey Post Hoc Test to identify the possible differences intra and intergroups. The α value used was 0.05. The GRPG present significant reduction at Cobb angle between pre and posttest (Δ%=-35.100; p=0.009), but the CG didn´t show (Δ%=9.520; p=0.789). It was concluded that scholars submitted to RPG method presented improvement in thoracic nonstructural scoliosis.
