Objective@#To explore the effects of community building environment and sports with fitness APP usage and their interactions on teachers exercise habits in the Yangtze River Delta Region, so as to provide a scientific basis for the development of a sports and health promotion intervention program for teachers.@*Methods@#A total of 2 530 in service teachers from four provinces and cities in the Yangtze River Delta region, namely, Shanghai, Zhejiang, Jiangsu and Anhui Province, were sampled in May-June 2023 by using convenient cluster random sampling method. Self designed questionnaire was used to collect the basic information of the surveyed teachers, Physical Activity Building Environment Evaluation Questionnaire and the Sports with Fitness APP Usage Questionnaire were used to measure the teachers subjective perception of the community building environment and the usage of sports with fitness APP, respectively. Physical Exercise Habituation Scale was used to assess the level of exercise habits. Logistic regression models were applied to analyze the effects of community building environment and sports with fitness APP usage on physical exercise, and the interaction effects were analyzed by using additive and multiplicative models.@*Results@#Among all the teachers surveyed, 658 of them reported good physical exercise habits (26.0%), and differences in the rate of physical activity habit formation by gender, age, years of teaching, as well as subject of teaching were statistically significant ( χ 2=42.94, 39.73, 35.47, 218.23 , P <0.05). Teachers with physical exercise habits had significantly higher community building environment scores and sports and fitness APP use than teachers without exercise habits ( t =12.17,16.54, P <0.05). Adjusting for the confounders of age, gender, years of teaching experience, and subjects taught, multifactorial unconditional Logistic regression analysis showed that the probability of teachers having good physical exercise habits increased by 22% for every 1-point increase in the community building environment score on average ( OR =1.22, 95% CI =1.11-1.40), and the probability of teachers having good physical exercise habits increased by 16% for every 1-point increase in the sports with fitness APP score on average ( OR = 1.16 , 95% CI =1.03-1.31) ( P <0.05). Interaction analyses showed that there was an additive interaction between the effects of community building environment and sports and fitness APP use on teachers physical exercise habits after adjustment, and the 95% CI for RERI , API and SI were 1.17 -1.65, 0.12-0.46 and 1.78-3.33 ( P <0.05), respectively, and there was no multiplicative interaction ( P >0.05).@*Conclusions@#The community building environment and the usage of sports & fitness APP show impacts in the formation of teachers physical exercise habits in the Yangtze River Delta region, and there is an interaction effect. Enhancing the construction of smart sports centers around the community can provide a high quality external environment for the physical exercise habits formation.

Desempenho no teste FMS® em mulheres e homens praticantes de exercício resistido / FMS® performance of women and men practicing resistance training

Introdução: Os exercícios resistidos (ER) compõem o programa de condicionamento físico de um grande número de indivíduos. Nesses programas são realizadas avaliações periódicas para planejamento e acompanhamento dos efeitos do treinamento. Recentemente, além das avaliações físicas tradicionais tem sido recomendada a inclusão de testes funcionais para avaliação do padrão de movimento dos indivíduos. Objetivo: Avaliar o desempenho funcional de mulheres e homens praticantes de ER. Métodos: Cinquenta e sete participantes (27 mulheres, 26,2 ± 5,1 anos; e 30 homens, 26,3 ± 5,8 anos) fisicamente ativos e experientes na prática de ER foram avaliados através da bateria de testes Functional Movement Screen (FMS®). O escore total foi comparado entre os sexos através do teste U de Mann-Whitney; já a distribuição dos escores parciais (escores de cada teste) e a proporção de escores assimétricos entre os grupos foram realizadas através do teste do Qui-Quadrado (p < 0,05). Resultados: O escore total das mulheres foi 14,6 ± 1,5 pontos, e o dos homens, 15,3 ± 1,4 pontos, de modo que não houve diferença significativa entre os grupos. Considerando os escores parciais, os homens apresentaram melhor desempenho no teste de estabilidade de tronco (p = 0,001) e de agachamento (p = 0,024), enquanto as mulheres apresentaram melhor desempenho no teste de mobilidade de ombros (p = 0,001). Neste último, além de apresentarem piores resultados, os homens foram significativamente mais assimétricos (p = 0,002). Conclusões: Os resultados deste estudo sugerem a necessidade de uma observação mais detalhada dos escores parciais para o planejamento de programas de treinamento personalizados, que atendam às necessidades de cada indivíduo.

Introduction: Resistance training (RT) is part of the physical fitness program of a large number of people. In these programs, periodic evaluations are carried out to plan and monitor the effects of training. Recently, in addition to the traditional physical evaluations, it has been recommended the inclusion of functional tests to evaluate the movement pattern of individuals. Objective: To assess the functional performance of women and men participating of RT. Methods: Fifty-seven participants (27 women, 26.2 ± 5.1 years old; and 30 men, 26.3 ± 5.8 years old), who are physically active and experienced in RT, were assessed through the use of Functional Movement Screen (FMS®). The total score was compared between the genders using the Mann-Whitney U test, and the distribution of the partial scores (scores of individual tests) and the proportion of asymmetric scores between groups was performed through the Chi-Square test (p < 0.05). Results: Women and men presented, respectively, a total score of 14.6 ± 1.5 and 15.3 ± 1.4 points, and there was no significant difference between genders. Considering the partial scores, men performed better in the trunk stability (p = 0.001) and deep squat (p = 0.024) tests, while women presented higher scores in the shoulder mobility test (p = 0.001). In the latter, besides presenting worse results, men were significantly more asymmetrical (p = 0.002). Conclusions: The results of this study suggest the necessity of a more detailed observation of the partial scores in order to plan personalized training programs that consider the participants' individual needs.

Clasificación de los medios y métodos empleados en el entrenamiento funcional de alta intensidad: una reflexión crítica

El entrenamiento funcional de alta intensidad representa un nuevo paradigma del fitness, además es un tipo de ejercicio que crece a nivel mundial en cuanto a practicantes y centros de acondicionamiento físico que lo ofertan; no obstante, la documentación respecto a la forma de realizar este tipo de entrenamientos es escasa, por lo que se puede presentar diferentes problemáticas en este ámbito de la actividad física, el deporte y la salud por desconocimiento de cómo efectuar este tipo de ejercicio físico de alta intensidad. El objetivo estudio de este artículo es hacer una reflexión crítica sobre los medios y métodos aplicados en el entrenamiento funcional de alta intensidad. Posterior a la consulta de literatura se propone la siguiente clasificación para los medios (calisténicos/gimnásticos, cardiometabólico y levantamiento), mientras que los métodos obtuvieron dos clasificaciones, una basada en la modalidad (medios) y otra en la organización (estructura de la sesión). En conclusión, esta nueva propuesta se ajusta más a la realidad del entrenamiento funcional de alta intensidad desde las bases del entrenamiento deportivo.

High-intensity functional training represents a new fitness paradigm, it is also a type of exercise that is growing worldwide in terms of practitioners and fitness centers that offer it, despite the documentation regarding how to perform this type of exercise is scarce, so different problems can arise in this area of physical activity, sports and health due to a lack of knowledge of how to carry out this type of high-intensity physical exercise. The study objective of this article is to make a critical reflection on the means and methods applied in high intensity functional training. After consulting the literature, the following classification is proposed for the means (calisthenics/gymnastics, cardiometabolic and lifting), while the methods obtained two classifications, one based on the modality (means) and the other on the organizational (structure of the session). In conclusion, this new proposal is more in line with the reality of high-intensity functional training from the bases of sports training.

A resistência do fluxo inspiratório modifica a intensidade de uma sessão de pilates? / Does inspiratory flow resistance modify the intensity of a pilates session?

INTRODUÇÃO: As evidências sobre a melhora da capacidade funcional utilizando o Método Pilates não são contundentes. Uma possibilidade de melhorar o efeito de uma sessão de Pilates sobre a capacidade cardiorrespiratória de seus praticantes é utilizar a resistência de fluxo inspiratório (RFI) de forma concomitante. Esse efeito pode ser visualizado através da determinação do limiar glicêmico (LG), técnica utilizada como marcador de intensidade do exercício. OBJETIVO: Testar a hipótese de que a utilização de RFI em uma sessão de pilates antecipa o LG. MÉTODOS: Estudo crossover de corte transversal. Foram avaliados 26 indivíduos de ambos os sexos, sendo 10 do sexo masculino, sadios e com idade entre 20 e 40 anos. Os voluntários foram randomizados para dois protocolos: Protocolo RFI ­ 11 movimentos do Método Pilates com RFI utilizando 20% da pressão inspiratória máxima; e Protocolo sem RFI (SRFI) ­ 11 movimentos do Método Pilates sem RFI. Os dois protocolos foram realizados no mesmo dia, sendo um pela manhã e outro à tarde, conforme randomização feita por sorteio aleatório simples. No repouso e ao final de cada movimento coletas de sangue capilar foram realizadas para dosagem da glicemia e construção da curva glicêmica. O LG foi determinado no menor ponto da curva. RESULTADOS: O LG foi antecipado no protocolo que utilizou RFI, ou seja, no protocolo com RFI o LG foi visualizado no sexto exercício, enquanto no protocolo SRFI o LG foi visualizado no nono exercício (p<0,05). CONCLUSÃO: A RFI antecipou o LG, o que sugere que a RFI aumenta a intensidade de uma sessão de pilates. Isso aventa a hipótese de que a RFI pode proporcionar a médio e longo prazo benefícios adicionais aos praticantes do Método Pilates.

INTRODUCTION: The evidence on the improvement of functional capacity using the Pilates Method is not conclusive. One possibility to improve the effect of a Pilates session on the cardiorespiratory capacity of its practitioners is to use the inspiratory flow resistance (IFR) concomitantly. This effect can be visualized by determining the glycemic threshold (GT), a technique used as an exercise intensity marker. OBJECTIVE: To test the hypothesis that the use of IFR in a Pilates session anticipates GT. METHODS: Cross-sectional crossover study. A total of 26 individuals of both genders were evaluated, 10 of whom were male, healthy, and aged between 20 and 40 years. The volunteers were randomized to two protocols: Protocol IFR - Eleven movements of the Pilates method with IFR using 20% of the maximum inspiratory pressure, and Protocol no IFR (NIFR) - Eleven movements of the Pilates method without IFR. The two protocols were performed on the same day, one in the morning and the other in the afternoon, according to randomization by simple random draw. At rest and at the end of each movement, capillary blood collections were performed to measure blood glucose and construct the glycemic curve. GT was determined at the smallest point on the curve. RESULTS: The GT was anticipated in the protocol that used IFR; that is, in the protocol with IFR, the GT was visualized in the sixth exercise, while in the NIFR protocol, the GT was visualized in the ninth exercise (p<0.05). CONCLUSION: IFR anticipated GT, which suggests that IFR increases the intensity of a Pilates session. This suggests the hypothesis that IFR can provide additional medium and long-term benefits to Pilates method practitioners.

Abstract Objective Verify the effect of Pain Neuroscience Education combined with Pilates on catastrophizing in older people with chronic non-specific low back pain. Methods A randomized controlled clinical trial with 80 participants divided into two groups: Pilates combined with Pain Neuroscience Education Group - PEG, and Pilates Group - PG. The measurements were taken at baseline, post-intervention, and after 6 months (follow-up). The protocol included three individual 30-min PNE sessions (only for PEG) and, after that, 8 weeks of Pilates (twice a week, 50 min/session, for both groups). Results Comparisons of pre-post and follow-up differences in catastrophizing, kinesiophobia, disability, and pain intensity showed no evidence that PNE had any additional effects when compared with exercises alone. One likely advantage of the present PNE protocol was that the dropout rates for the PEG group were lower than for the PG group, showing that PNE has increased exercise adherence. Conclusion The clinical relevance of the study is that Pilates is a safe intervention for older people with non-specific chronic low back pain, and that PNE can increase adherence to exercise for this population.

The average heart rates of male and female students in physical education class were (144.22±24.95) and (136.31±28.78) counts/min, and the difference was not statistically significant ( t=4.04, P >0.05). The cumulative durations of effective exercise load among male and female students were (34.08± 7.52 ) and ( 28.43 ±5.39) min, respectively. The average TRIMP value for physical fitness classes were (100.46±16.56), with a exercise density of 72.06%.@*Conclusions@#The exercise intensity of physical fitness classes for secondyear junior high school students in Beijing is appropriate, mainly with moderate to vigorous intensity, and the accumulated time of MVPA is sufficient. The average heart rate and exercise density of students meet the requirements. Scientific setting of physical fitness class exercise load should be based on individual differences in students physical fitness, in order to improve the physical health level of middle school students.

Correlation between academic stress and extracurricular physical exercise among college students / 中国学校卫生

Objective@#The study aimed to investigate the relationship between academic stress and extracurricular physical exercise among college students, with the goal of providing evidence and reference for effectively alleviating academic stress.@*Methods@#A stratified cluster random sampling method was employed, along with the Chinese College Student Psychological Health Screening Scale and a self designed questionnaire. In January 2023, an online survey was conducted among 1 108 college students from eight colleges and universities in Jiangsu Province. Statistical analyses included independent samples t test, one way analysis of variance (ANOVA) and the optimal scale regression model.@*Results@#It revealed that 50.8% of students worried about falling behind their peers in their studies, 51.7% expressed concerns about exams, 21.7% exerted significant effort but still struggled to keep up with the pace of learning, and 24.9% felt difficulties in their studies. The overall index of academic stress was higher among undergraduate institutions, first year students, female students, and urban residents ( t/F =3.66, 10.96, -5.46, 3.52, P <0.01). The average time of weekly extracurricular physical exercise for students was (2.35±2.18)h, and there were significant differences by gender, only child status, and grade groups( t/F =2.35, 4.66, 7.09, P <0.05). The optimal scale regression model analysis ( R 2=0.17, F=32.03, P <0.01) revealed that the regression coefficient and partial correlation coefficient between academic stress and extracurricular physical exercise time were both -0.33( P <0.01). The importance of extracurricular physical exercise in the model was 0.66, with a tolerance value of 0.97. The regression coefficients and partial correlation coefficients for academic stress and extracurricular physical exercise time were -0.35, -0.35 for undergraduate students, and -0.31, -0.32 for junior college students ( P < 0.01 ).@*Conclusion@#A significant number of college students experience varying degrees of academic stress, and their engagement in extracurricular physical exercise is insufficient. There is a negative association between academic stress and extracurricular physical activity time among college students. Universities should encourage students to increase extracurricular physical activity time to reduce academic stress and promote college students mental health.

Methods Junior table tennis students from a university were randomly divided into experimental and control groups. The control group had routine training while the experimental group had a protocol with lower limb training added. Results There was a statistical difference in the forward jump from 225.268 (± 13.229) cm before the experiment to 269.127 (± 9.331) cm after the experiment, and the left and right inclined jump values also followed this pattern after the experiment. The standing jump distance of the control group increased from 220.077 (± 21.124) cm before the experiment to 258.122 (± 15.1301) cm after the experiment. Conclusion Habitual sports training positively impacts table tennis players, but the effect is relatively slow and has low training efficiency. The lower limb strength training scheme proposed in this study showed improved sporting efficiency in athletes and expressive gains in their lower limb strength, positively impacting dynamic balance ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Os Benefícios dos Exercícios Físicos no Câncer de Mama / The Benefits of Exercise in Breast Cancer

Resumo O câncer de mama é a neoplasia mais prevalente nas mulheres, em torno de 30% de todos os tipos de câncer, enquanto no sexo masculino é responsável por apenas 1% dos casos. No mundo, é a primeira causa de morte por câncer em mulheres. A incidência e a mortalidade variam de acordo com a etnia, região territorial e nível socioeconômico. Em virtude da baixa prevalência do câncer de mama em homens e a escassez de literatura, as condutas são baseadas em extrapolações dos estudos no sexo feminino. As evidências científicas sugerem efeitos benéficos dos exercícios físicos na prevenção, durante o tratamento e no pós-tratamento do câncer de mama. Além do combate ao sedentarismo, é importante manter um peso saudável, limitar o consumo de álcool, e seguir dieta balanceada, rica em frutas, vegetais, grãos e fibras e reduzida em carnes vermelhas. As ações dos exercícios não se restringem ao câncer de mama, mas têm impacto importante no controle dos fatores de risco modificáveis, diminuindo a incidência das doenças cardiovasculares e a mortalidade por causas globais e cardíaca.

Abstract Breast cancer is the most prevalent cancer among women, accounting for nearly 30% of all cancers, while in men, it represents only 1% of cases. Breast cancer is the main cause of death for cancer, and its incidence and mortality vary according to patients' ethnicity, geographic region, and socioeconomic status. Due to the low prevalence of breast cancer among men and the scarcity of studies in the literature, exercises have been prescribed based on extrapolations from studies on female patients. Scientific evidence has suggested beneficial effects of physical exercises on breast cancer prevention, treatment, and post-treatment. In addition to combatting sedentary behavior, it is essential to maintain a healthy body weight, limit alcohol consumption, and follow a balanced diet, rich in fruit, vegetables, grains and fibers, and limited in red meat. The effects of exercises are not restricted to breast cancer, but extend to controlling modifiable risk factors, and reducing the incidence of cardiovascular diseases, and all-cause and cardiovascular mortality.

Pilates method on pain in patients with low back pain: systematic review / Método Pilates para dor em pacientes com lombalgia: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: The weakness of the trunk extensors is one of the main causes in the development of low back pain in a large part of the population. Low back pain is a disabling condition and due to the pain many people have difficulty performing activities of daily life. Thus, Pilates becomes one of the methods of choice in the treatment of low back pain because it brings muscle strengthening exercises that positively impact the stabilization of the spine. The objective of this study was to review the impact of the Pilates method on pain in patients with low back pain. METHODS: This is a systematic review, with search for data in the Scielo, OVID, Lilacs, Pubmed and PEDro databases, which included randomized clinical trials that addressed the Pilates method in patients with low back pain. The following search descriptors were used: low back pain, Pilates method, exercise movement techniques. The Boolean operators were: "and" and "or". RESULTS: Of the 8 selected studies, all obtained positive results in the reduction of low back pain, each using a different protocol associated with physical therapy treatment. Of the eight studies considered eligible, only seven were included. For the study of this comparison, a random model was used (I2=92%, df=6, p=0.01), in which there was a statistically significant diference between the Pilates and control groups (95% CI -1.79, -0.19). CONCLUSION: It was possible to conclude that the Pilates method he was effective in the treatment of low back pain. HIGHLIGHTS The study reinforces the importance of the Pilates method for patients with low back pain, focusing on pain reduction, but with an impact on functionality and quality of life. The role of Pilates as an integral part of a care protocol is also reinforced, not as the only tool for physical therapy care. The application of Pilates method should begin with exercises of mild to moderate difficulty and, with functional gain, progress to high complexity.

RESUMO JUSTIFICATIVA E OBJETIVOS: A fraqueza dos extensores de tronco é uma das principais causas no desenvolvimento de lombalgia em grande parte da população. A dor lombar é uma condição incapacitante e, devido à dor, muitas pessoas têm dificuldade para realizar as atividades de vida diária. Assim, o Pilates passa a ser um dos métodos de escolha para tratamento de pacientes com lombalgia, pois traz exercícios de fortalecimento muscular que promovem estabilização da coluna vertebral. O objetivo deste estudo foi analisar o impacto do método Pilates na dor de pacientes com lombalgia crônica. METODOS: Trata-se de uma revisão sistemática com busca de estudos nas bases de dados Scielo, OVID, Lilacs, Pubmed e PEDro incluindo ensaios clínicos randomizados que abordaram o método Pilates em pacientes com lombalgia crônica inespecífica. Os descritores de busca utilizados foram low back pain, Pilates method, exercise movement techniques, somados aos operadores booleanos: "e" e "ou". O risco de viés dos estudos foi avaliado de acordo com os critérios da escala PEDro. RESULTADOS: Dos 8 estudos selecionados, todos obtiveram resultados positivos na redução da dor lombar, cada um utilizando um protocolo diferente associado ao tratamento de fisioterapia. Dos oito estudos considerados elegíveis, apenas sete foram incluídos na meta-análise. Para a meta-análise desta comparação, foi utilizado um modelo randomizado (I2=92%, df=6, p=0,01), no qual houve uma diferença estatisticamente significativa entre os grupos Pilates e grupo controle (95% CI -1,79, -0,19). CONCLUSÃO: Foi possível concluir que o método Pilates foi eficaz no tratamento de dores lombares. DESTAQUES O estudo reforça a importância do método Pilates para pacientes com dor lombar, concentrando-se na redução da dor, mas com um impacto na funcionalidade e qualidade de vida. O papel do Pilates como parte integrante de um protocolo de tratamento também é reforçado, não sendo a única ferramenta para o tratamento fisioterápico. A aplicação do método Pilates deve começar com exercícios de dificuldade leve a moderada e, após o ganho funcional, progredir para alta complexidade.

Implementação Clínica de Diferentes Estratégias para Reabilitação Baseada em Exercícios em Receptores de Transplante de Rim e Fígado: Um Estudo Piloto / Clinical Implementation of Different Strategies for Exercise-Based Rehabilitation in Kidney and Liver Transplant Recipients: A Pilot Study

Resumo Fundamento: A doença cardiovascular está entre as principais causas de morte entre pacientes transplantados. Embora esses pacientes possam teoricamente se beneficiar de programas de reabilitação baseada em exercícios (RBE), sua implementação ainda é um desafio. Objetivo: Apresentamos nossa experiência inicial em diferentes modos de realização de um programa piloto de RBE em receptores de transplante de rim e fígado. Métodos: Trinta e dois pacientes transplantados renais ou hepáticos foram convidados para um programa de RBE de 6 meses realizado na academia do hospital, na academia comunitária ou em casa, de acordo com a preferência do paciente. O nível de significância adotado foi de 5%. Resultados: Dez pacientes (31%) não completaram o programa. Entre os 22 que completaram, 7 treinaram na academia do hospital, 7 na academia comunitária e 8 em casa. O efeito geral foi um aumento de 11,4% nos METs máximos (tamanho do efeito de Hedges g = 0,39). O grupo de academia hospitalar teve um aumento nos METs de 25,5% (g = 0,58, tamanho de efeito médio) versus 10% (g = 0,25) e 6,5% (g = 0,20) para os grupos de academia comunitária e em casa, respectivamente. Houve efeito benéfico nas pressões arteriais sistólica e diastólica, maior para os grupos academia hospitalar (g= 0,51 e 0,40) e academia comunitária (g= 0,60 e 1,15) do que para os pacientes treinando em casa (g= 0,07 e 0,10). Nenhum evento adverso significativo foi relatado durante o seguimento. Conclusão: Programas de RBE em receptores de transplante de rim e fígado devem ser incentivados, mesmo que sejam realizados fora da academia do hospital, pois são seguros com efeitos positivos na capacidade de exercício e nos fatores de risco cardiovascular.

Abstract Background: Cardiovascular disease is among the leading causes of death in solid organ transplant recipients with a functional graft. Although these patients could theoretically benefit from exercise-based rehabilitation (EBR) programs, their implementation is a challenge. Objective: We present our initial experience on different delivery modes of a pilot EBR program in kidney and liver transplant recipients. Methods: Thirty-two kidney or liver transplant recipients were invited for a 6-month EBR program delivered at the hospital gym, community gym or at home, according to the patient's preference. The significance level adopted was 5%. Results: Ten patients (31%) did not complete their program. Among the 22 who did, 7 trained at the hospital gym, 7 at the community gym, and 8 at home. The overall effect was an 11.4% increase in maximum METs (Hedges' effect size g = 0.39). The hospital gym group had an increase in METs of 25.5% (g= 0.58, medium effect size) versus 10% (g= 0.25), and 6.5% (g= 0.20) for the community gym and home groups, respectively. There was a beneficial effect on systolic and diastolic blood pressures, greater for the hospital gym (g= 0.51 and 0.40) and community gym (g= 0.60 and 1.15) groups than for the patients training at home (g= 0.07 and 0.10). No significant adverse event was reported during the follow-up. Conclusion: EBR programs in kidney and liver transplant recipients should be encouraged, even if they are delivered outside a hospital gym, since they are safe with positive effects on exercise capacity and cardiovascular risk factors.
