En las poblaciones pediatricas, ha aumentado el uso del grosor de la intima-media carotidea (IMT) como marcador del riesgo cardiovascular. Sin embargo, los estudios anteriores que examinaron los efectos del entrenamiento con ejercicios sobre la estructura y funcion arterial en ninos y adolescentes obesos han mostrado resultados inconsistentes. El objetivo principal de esta revision sistematica y metanalisis es ampliar el cuerpo actual de la bibliografia proporcionando una estimacion cuantitativa del cambio en la TMI carotidea despues del entrenamiento con ejercicios, asi como proporcionar un analisis exploratorio de los moderadores potenciales asociados con la variacion en respuesta a una intervencion de entrenamiento con ejercicios en jovenes con sobrepeso y obesos. METODOS: Se realizo una busqueda de la bibliografia mediante las bases de datos electronicas CENTRAL, EMBASE y MEDLINE. Los terminos utilizados fueron: ['Obesidad' y 'Sobrepeso' O], ['Ejercicio' y 'Entrenamiento' y 'Actividad fisica' y 'Deporte' O]. Todos los terminos de los encabezamientos de los temas medicos se combinaron con el grosor del intima-media* y los ninos y adolescentes como limitadores. No se exploraron los estudios informados en idiomas diferentes al ingles. El analisis se limito a los estudios que examinaron el efecto de las intervenciones con ejercicios sobre la IMT carotidea en la obesidad pediatrica (6-18 anos de edad). Se incluyeron seis ensayos controlados aleatorios (ECA) (303 jovenes). Se calcularon los intervalos de confianza del 95%.

METHODS: The randomized trial compared a 12-week progressive resistance exercise training (EX) with a 12-week relaxation control group. In 103 chemotherapy-naïve participants, interleukin-6 (IL-6) and interleukin-1 receptor antagonist (IL-1ra) were measured in serum samples collected before, at the end, and 6-weeks post-radiotherapy. Fatigue was assessed with the multidimensional Fatigue Assessment Questionnaire (FAQ), and pain with the EORTC QLQ-C30. Analysis of covariance (ANCOVA) models, partial correlations, Freedman-Schatzkin tests, and R 2 effect-size measures for mediation were calculated. RESULTS: The ANCOVA models revealed a significant intervention effect on IL-6 (p=0.010) and the IL-6/IL-1ra ratio (p=0.018), characterized by a marked increase during radiotherapy among controls, but no significant change in EX. IL-1ra did not change significantly in either group (p=0.88). Increased IL-6 and IL-6/IL-1ra levels at the end of radiotherapy were significantly associated with increased physical fatigue and pain 6 weeks post-radiation. The effect of resistance exercise on physical fatigue was significantly mediated by IL-6 and IL-6/IL-1ra, but not by IL-1ra. IL-6 and IL-6/IL-1ra mediated between 15% and 24% of the variance of physical fatigue and pain explained by the intervention. CONCLUSIONS: This randomized controlled trial showed a significantly increased pro-inflammatory cytokine level after adjuvant radiotherapy in breast cancer patients. This effect was counteracted by progressive resistance exercise training. IL-6 and the IL-6/IL-1ra ratio appeared to mediate the beneficial effect of exercise on physical fatigue and pain, but only to a small extent.

PURPOSE: The mechanisms to explain the protective metabolic effects of breaking up sitting time remain unexplained. Meanwhile, there is limited evidence to suggest both older and younger adults respond similarly to sedentary behavior (SB) alternatives. The purpose of this study is compare physiological responses SB alternatives in young and old adults. METHODS: Eleven younger adults (21-35 yr) and eleven older adults (62-76 yr) performed five randomly ordered 20-minute tasks: 1) continuous chair sitting, 2) continuous stability ball sitting, 3) continuous desk standing, 4) sitting interrupted by 2-minutes walking, and 5) sitting interrupted by 2-minutes standing. Muscle activation was determined by percent normalized electromyography amplitude (%NEA) of upper (trapezius and erector spinae) and lower (rectus femoris and medial gastrocnemius) body muscles and total body energy expenditure (EE) was collected via indirect calorimetry. Linear mixed effects models controlling for gender with a Tukey post-hoc analysis were used to determine significant differences between age groups and across tasks. RESULTS: For both age groups, lower body muscle activation and EE were significantly influenced by the SB alternatives (p<0.01) with no differences present between age groups. Upper body muscle activation in response to the SB alternatives were not consistent between younger and older adults (p<0.05). Specifically, younger adults did not show a significant difference in upper body muscle activation between tasks, while older adults showed a significantly higher upper body muscle activation during the sitting interrupted by walking task compared to all other tasks (p<0.05). The upper body muscle activation during the sitting interrupted by walking task in older adults (10.8 ± 1.5% max) was over twice the activation level of younger adults (4.8 ± 0.6% max, p<0.05). CONCLUSIONS: SB alternatives had little effect on upper body musculature of young adults, while older adults required twice the muscle activation of younger adults to perform an interrupted walking task. Whether age-related divergences in muscle activation differentially affect metabolic health markers needs to be determined.

RESULTS: Children who were overweight or obese performed 8.6 points lower on the TMGD-3 compared to children who had healthy BMI (β = −8.6, p < 0.001) and performed 5.9 points lower on the locomotor sub-test compared to children who had healthy BMI (β = −5.9, p < 0.001) after controlling for grade level, sex, and classroomlevel clustering. There were no significant predictive relationships between BMI classification and the ball skill sub-test scores (p > 0.01). CONCLUSION: Overweight and obese disadvantaged children tended to have poorer performance on the locomotor sub-test of the TGMD-3 compared to children with a healthy BMI, suggesting the importance of learning these fundamental skills at an early age.
结果:在控制年级水平、性别和班级水平聚类后，超重或肥胖儿童的TMGD-3得分比BMI健康儿童低8.6分(β = - 8.6, p < 0.001)，运动亚测试得分比BMI健康儿童低5.9分(β = - 5.9, p < 0.001)。BMI分类与球技分项测试得分无显著预测关系(p > 0.01)。结论:超重和肥胖弱势儿童在TGMD-3运动亚测试中的表现往往低于BMI健康儿童，提示早期学习这些基本技能的重要性。

PURPOSE:Many believe that routine excercises in Wushu routine (Kungfu) are mere acrobatics and have no fighting value compared to other martial arts. The aim of this study was to compare the straight punch force between Wushu and other martial artists. METHODS:35 male college students who have equal sport experiences were eligible for this study. Boxing n=7, San Da (Chinese Sparring) n=7, Wushu routine n=7, Karate n=7, control group (College Physical education students) n=7 took part in this trial. Subjects age were 21±1 years old, weight 66.7±6.4 kg, height 1.71±0.23 cm. Except for the control group, the average of training years was 6±3 years. Subjects were asked to deliver a straight punch under 2 conditions. 1) A free punch was tested for subjects’ maximum punch force. 2) A reaction punch with a signal was used to test subjects’ reaction and punch force. A punch test device was used to collect punch force and acceleration. The sampling frequency of force and acceleration was 10,000 Hz respectively. Subjects test order was randomized prior to the experiment begin. Punch force was normalization. Statistical analyses were performed using SPSS 19.0. ANOVA repeat measures were used to compare the differences of two punch conditions and groups. Data were reported as mean values (SD), and the significance level was set to p < 0.05. RESULTS:The results showed that the maximum punch force was highest for boxers (2689 N), followed by practitioners of San Da (2653 N), Wushu routine (2258 N), karate (1914 N) and PE students (1380 N). The results for the reactive punch force showed slight differences with San Da players (2532 N) now scoring higher than boxers (2481 N). Also for the free punch acceleration the highest scores were registrered among San Da players (122 m/s2), followed by Wushu routine (119 m/s2), boxing (113 m/s2), karate (89 m/s2) and the control group (68 m/s2). The same order was found for the reactive acceleration: San Da (122 m/s2), Wushu routine (119 m/s2), Boxing (113 m/s2), Karate (89 m/s2) and the control group (68 m/s2). CONCLUSIONS:This comparison indicated that the straight punch force of Wushu routine was lower than that of boxing and San Da, but higher than that of karate and P.E students. Wushu routine is a promising self-defense sport that can be known by more people.

CONCLUSIONS:This comparison indicated that the straight punch force of Wushu routine was lower than that of boxing and San Da, but higher than that of karate and P.E students. Wushu routine is a promising self-defense sport that can be known by more people.","PeriodicalId":18500,"journal":{"name":"Medicine & Science in Sports & Exercise","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75007580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
