Quando lazer e saúde se encontram: uma aproximação teórica possível para a composição de práticas cotidianas / When leisure and health meet: a possible theoretical approach for the composition of everyday practices

A vida cotidiana, para além de um conjunto de atividades desenvolvidas e vivenciadas ao longo dos dias, é também um tempo recheado de sentidos e significados. Inseridos nesse tempo, estão o lazer e a saúde, elementos centrais para a manutenção da vida individual e coletiva. Inseridos também em diferentes currículos acadêmicos, estes grandes campos de conhecimento são, muitas vezes, apresentados e tratados de forma separada durante o processo de formação acadêmica profissional. Este texto, fruto de uma Residência pós-doutoral no Programa de Pós-Graduação Interdisciplinar em Estudos do Lazer, é uma composição conjunta entre um terapeuta ocupacional e um profissional de Educação Física, na tentativa de aproximar os núcleos de conhecimento e apresentar uma nova possibilidade de abordagem para os Estudo do Lazer.

Everyday life, in addition to a set of activities developed and experienced throughout the day, is also a time filled with meanings and meanings. Included in this time are leisure and health, central elements for maintaining individual and collective life. Also included in different academic curricula, these major fields of knowledge are often presented and treated separately during the process of professional academic training. This text, the result of a post-doctoral residency in the Interdisciplinary PostGraduate Program in Leisure Studies, is a joint composition between an occupational therapist and a Physical Education professional, in an attempt to bring knowledge centers closer together and present a new possibility approach to Leisure Studies.

Objective@#To investigate the effects of after school exercise service (referred to as the "after school ES") on physical health, so as to provide evidence for possible beneficial effect of after school ES.@*Methods@#Students in the fourth grade of primary school were recruited from September 2021 to July 2022 in Changsha City and divided into the control group ( n =220) and the after school ES group ( n =220). The control group only participated in the regular physical education activities of the school. The after school ES group received after school ES for one academic year, 4 times a week, 40-50 minutes per time, for a total of 32 weeks. Body shape indicators such as height, weight and percentage of body fat, as well as physical fitness indicators such as 50 meter running, grip strength and progressive aerobic cardiovascular endurance run (PACER) were measured in September to October 2021 and June to July 2022, respectively. Independent sample t-test, Chi square test and two factors repeated measurement analysis of variance were used for statistical analysis of the data.@*Results@#After one academic year, compared with the control group [(13.52±2.30)kg], muscle mass of primary school students in the after school ES group [(13.76±2.32)kg] significantly increased, while waist to hip ratio [(0.95±0.16)] and percentage of body fat [(20.17±7.43)%] significantly decreased compared to the control group [(1.01±0.21), (22.02±12.34)%]( F=330.70, 6.85, 4.33, P <0.05). The proportion of overweight and obesity in after school ES group decreased significantly from 19.5% to 12.3% ( χ 2=4.35, P <0.05). Compared with the control group, the scores of 50 meter running [(10.00±1.06, 10.21±0.83)s], 1 minute sit up [(33.25±8.24, 30.76±9.34)times], sitting and flexion [(14.53±7.50, 8.59±6.32)cm], 1 minute rope skipping [(125.01±30.50, 115.97±32.09)times], eyes closed and single legged standing [(30.00±34.72, 25.72±23.82)s], selective response time [(635.66±91.72, 652.79±120.42)ms] and VO 2max [(45.31± 1.02 , 43.67±0.85)mL/(kg〖 ·min)] in the after school ES group were significantly improved, with statistical significance ( F= 5.32 , 443.14, 97.23, 814.07, 36.49, 6.11, 396.91, P <0.05).@*Conclusions@#After school ES can improve body shape of primary school students, reduce the risk of overweight and obesity and enhance physical fitness.

Intervention effect of 12 week spinal health gymnastics on high and low shoulder exercise in adolescents / 中国学校卫生

Objective@#To explore the intervention effect of 12 week spinal health exercise on adolescents high and low shoulders, in order to provide empirical evidence for exploring simple and feasible measures to intervene.@*Methods@#In February 2023, 60 high and low shoulder students from a vocational high school in a certain county of Luzhou City were randomly selected as the research subjects by convenient sampling method. Paired sampling was used to randomly divide participants into an intervention group and a control group with 30 students each group. The intervention group received spinal health gymnastics intervention during 12 weeks of morning exercises and large break exercises for twice a day, with two groups each time; the control group maintained their previous morning exercises and large break exercises. A follow up study was conducted on the height difference between the left and right shoulder peaks of the intervention group and the control group students before intervention, after 12 weeks intervention, at 4 weeks post intervention. The t-test was used to analyze the changes in shoulder peak height difference between the intervention group and the control group.@*Results@#Before intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(2.50±1.19)cm] and the control group [(2.49±1.20)cm] adolescents ( t=0.05, P > 0.05). After 12 weeks of intervention, the difference in shoulder height between the left and right sides of adolescents in the intervention group decreased, compared to that before intervention [(1.43±1.15, 2.50±1.19)cm], while the control group increased compared to that before intervention [(2.58±1.19, 2.49±1.20) cm], and the differences were both statistically significant ( t= -78.17 , 20.15, P <0.05). At 4 weeks post intervention, there was no statistically significant difference in the height of the left and right shoulder peaks between the intervention group [(1.44±1.15)cm] and the control group [(2.59±1.18)cm] compared to 12 weeks after the intervention ( t=1.80, 1.05, P >0.05). The intervention group [(2.49±1.26, 2.52±1.16) (1.43±1.21, 1.44±1.13) (1.44±1.21, 1.45±1.14)cm] and the control group [(2.45±1.24, 2.52±1.20) (2.55±1.24, 2.61±1.18) (2.55±1.22, 2.62±1.18)cm] showed no statistically significant difference in the height of the left and right shoulder peaks between males and females before intervention, after 12 weeks of intervention, and after stopping intervention for 4 weeks ( t =-0.08, -0.03, -0.02; -0.15, -0.12, -0.15, P >0.05).@*Conclusions@#Spinal health gymnastics has a good effect on correcting high and low shoulders in adolescents. Spinal health gymnastics should be promoted on campus to promote adolescent posture health.

Objective@#To analyze the effects of 12week highintensity fitness exercise on body composition,lipid metabolism and gut microbiota in obese adolescents, so as to provide references for improving the health levels of obese adolescents.@*Methods@#From January to June 2023, 20 obese adolescents from Huaifeng Vocational and Technical School in Huaian City were recruited for the study. Participants were assigned to an exercise group (n=10) and a control group (n=10) for a 12week exercise intervention by random number table method, and both groups had the same diet during the intervention period. The exercise group engaged in three exercises every week, mainly consisting of moderate to highintensity aerobic exercise combined with highintensity intervals. In the first week, there was a 30 minutes of aerobic exercise, followed by 10 minutes of highintensity interval training in the total intervention time each week, and the rest of the time was aerobic exercise with a total intervention time of 60 minutes to maintain; the control group did not receive specific interventions. Body composition was measured using bioelectrical impedance analysis, and lipid levels were determined using an automatic biochemical analyzer. The expression levels of serum inflammatory factors were measured at baseline and after 12 weeks of intervention, and gut microbiota was analyzed using 16S rRNA gene sequencing. Statistical analysis was performed using t test and Chisquare test.@*Results@#After 12 weeks of intervention, the levels of triglycerides (TG), and lowdensity lipoprotein cholesterol (LDL-C) in obese adolescents in the exercise group decreased from (1.7±0.6, 3.5±0.8) mmol/L to (0.9±0.3, 2.6±0.4) mmol/L, while highdensity lipoprotein cholesterol (HDL-C) increased from (1.1±0.2) mmol/L to (1.4±0.2) mmol/L; and serum interleukin-1 receptor antagonist(IL-1Rn) decreased from (8.4±1.6) to (4.5±0.4) ng/mL in the exercise group (t=7.34,2.49,-3.05,2.56, P<0.05). The α-diversity results showed that the Chao index (268.00±22.67) and Ace index (243.98±38.64) in the exercise group were higher than those in the control group (184.52±19.28, 171.43±23.33), and the differences were statistically significant (t=2.48, 2.53, P<0.05). The Shannon index (5.36±1.41) in the exercise group was higher than that in the control group (4.73±1.12), and the Simpson index (0.78±0.10) was lower than that in the control group (0.89±0.10), but the differences were not statistically significant (t=1.83, -2.10, P>0.05). The β-diversity results showed that the intergroup differences in gut microbiota structure between the exercise group and the control group were greater than the intragroup differences, and the differences in gut microbiota structure between the exercise group and the control group were statistically significant (R2=0.083，P<0.05). After intervention, there were significant differences in the relative abundances at the levels of phylum, class, genus, and species in gut microbiota among obese adolescents between the exercise group and the control group (P<0.05).@*Conclusion@#The 12week highintensity fitness exercise can alleviate obesity symptoms in obese adolescents through the gut microbiota-lipid metabolism pathway and improve mild chronic inflammatory status.

La obesidad infantil, un problema de salud que demanda urgentes intervenciones educativas

La obesidad constituye un problema de salud global que afecta no solo a adultos, sino también a niños y adolescentes, por lo cual se reconoce la necesidad de adaptar los programas de intervención educativa del Ministerio de Educación, en asociación con el Ministerio de Salud Pública, para su adecuación al universo infantil. Se ha demostrado en la práctica que la actividad física es un espacio idóneo para la inclusión educativa de todos los escolares; se ha pasado del paradigma de la integración al paradigma de la inclusión, donde todos disfrutan de una atención diferenciada según sus carencias. Es propósito de los autores comunicar acerca de una intervención educativa aplicada a niños de 9 años que presentan obesidad y sobrepeso, con acciones que modifican su estilo de vida y educan a la familia para enfrentar este alarmante problema de salud en dicho grupo etario.

Obesity is a global health problem that affects not only adults and older adults, but also children and adolescents, thus recognizing the need to adapt the educational intervention programs of the Ministry of Education, in partnership with the Ministry of Public Health, to adapt them to the children's universe. It has been demonstrated in practice that physical activity is an ideal space for the educational inclusion of all schoolchildren; we have moved from the paradigm of integration to the paradigm of inclusion, where everyone enjoys differentiated attention according to their needs. It is the authors' purpose to communicate about an educational intervention applied to 9-year-old children with obesity and overweight, with actions that modify their lifestyle and educate the family to face this alarming health problem in this age group.

The influence of physical education at school on the attention of students aged 15-16 years / El impacto de la educación física en la escuela en la atención de los estudiantes de 15 a 16 años / O impacto da educação física na escola na atenção de estudantes de 15 a 16 anos

ABSTRACT Objectives: the influence of physical activity in physical education lessons on the attention indicators of schoolchildren. Material and Methods: 141 students, aged 15-16, who studied in the 9th grade, took part in the experiment. The main research method was the "Trondyke Test", which determines the level of attention development of students. The test was used before and after the physical education lesson 1 time per month for 5 months. Results: students who did not engage in physical education in the lesson were not able to significantly improve their performance in the test, which indicates a possible adaptation to the test after its first performance before the lesson. Students who were engaged in physical exercises could significantly increase the test results. Conclusion: the results obtained determine the effectiveness of the influence of a physical education lesson at school on the indicators of students attention. This study will serve as an additional motivation for students to engage in physical culture, since the impact of physical exercises has a positive effect not only on the development of physical qualities, but also on the attention of schoolchildren. Level of Evidence III; Retrospective Comparative Study.

Ação de algoritmos e a constituição de uma bolha fitness: o caso do personal trainer digital / Action of algorithms and the formation of a fitness bubble: the case of the digital coach / Acción de algoritmos y formación de una burbuja fitness: el caso del entrenador personal digital

Considerando a rede complexa em torno de um software que prescreve exercícios físicos com base em inteligência artificial, o presente estudo tem por objetivo analisar a constituição de uma bolha fitness e seus custos em potencial. Baseados na Teoria Ator-Rede, examinamos a interação entre atores humanos e não humanos nesse ambiente, destacando a influência dos algoritmos. A partir da noção de bolha fitness, exploramos como essa personalização pode levar os usuários a uma exposição predominante a conteúdos que reforçam suas visões e comportamentos atuais. Ao discutir suas possíveis consequências, evidenciamos a constituição de uma predição informacional, uma restrição da criatividade e um invisibilização do diferente. Portanto, nossa análise destaca os desafios e as implicações éticas associadas à formação e ao enclausuramento na bolha fitness, oferecendo uma reflexão sobre os custos potenciais desse fenômeno na era digital.

Considering the intricate network surrounding a software that utilizes artificial intelligence to prescribe physical exercises, this study aims to analyze the formation of a fitness bubble and its potential ramifications. Drawing upon the Actor-Network Theory, we scrutinize the interplay between human and non-human actors within this milieu, with a particular focus on the sway of algorithms. Building upon the concept of a fitness bubble, we delve into how this tailored approach might lead users towards a predominantly exposure to content that reinforces their existing beliefs and behaviors. In delving into its possible outcomes, we shed light on the emergence of informational prediction, a stifling of creativity, and an invisibility of diversity. Consequently, our analysis underscores the challenges and ethical implications tied to both the inception and entrenchment within the fitness bubble, offering a critical examination of the potential costs associated with this phenomenon in the digital era.

Basándonos en la Teoría Actor-Red, examinamos la interacción entre actores humanos y no humanos en este entorno, enfatizando la influencia de los algoritmos. A partir del concepto de una burbuja de fitness, exploramos cómo este enfoque personalizado podría llevar a los usuarios a una exposición predominante a contenidos que refuerzan sus creencias y comportamientos actuales. Al discutir sus posibles consecuencias, destacamos la aparición de la predicción informativa, una restricción de la creatividad y una disminución de la diversidad. En consecuencia, nuestro análisis subraya los desafíos y las implicaciones éticas asociadas tanto con la formación como con el enclaustramiento en la burbuja fitness, ofreciendo una reflexión sobre los posibles costos de este fenómeno en la era digital.

O objetivo desse estudo foi avaliar o impacto da pandemia da COVID-19 na produção de artigos de Educação Física com idosos. Nesse estudo bibliométrico, 558 pesquisadores de programas de pós-graduação do Brasil na área da Educação Física tiveram sua produção científica avaliada entre os anos 2018 e 2022. Foram incluídos apenas artigos cujo público-alvo era idoso. Os artigos foram analisados segundo os estratos Qualis e o fator de impacto das revistas. De um total de 17.932 artigos, 969 eram estudos com idosos. Durante a pandemia, houve uma queda na quantidade de artigos publicados sobre idosos (P = 0,001), com piora nos estratos Qualis (P = 0,001). O fator de impacto das revistas não foi afetado pela pandemia (P = 0,426). Os resultados apontam impacto da pandemia da COVID-19 na produção de artigos sobre idosos, fato que deve ser considerado por agências de fomento antes de avaliar pesquisadores e programas.(AU)

This study aimed to assess the impact of the COVID-19 pandemic on the production of Physical Education articles involving older individuals. In this bibliometric study, 558 researchers of Physical Education graduate programs in Brazil were evaluated between 2018 and 2022. Only articles targeting older individuals were included. The articles were analyzed based on Qualis ranking and the journals' impact factors. Out of a total of 17,932 manuscripts, 969 involved older individuals. During the COVID-19 pandemic, there was a decline in the number of articles published with older adults (P = 0.001), accompanied by a worsening of Qualis ranking (P = 0.001). The COVID-19 pandemic, differently, did not affect the impact factor of the journals (P = 0.426). The findings highlight the impact of the COVID-19 pandemic on the production of articles with older individuals, reinforcing the need for funding agencies to consider this aspect before evaluating researchers and programs.(AU)

Inserção de profissionais de educação física no Sistema Único de Saúde: análise temporal (2007-2021) / Insertion of physical education professionals in the Unified Health System: temporal analysis (2007-2021)

O objetivo desta pesquisa foi descrever e analisar a série temporal da inserção de profissionais de educação física (PEF) no Sistema Único de Saúde (SUS) no período de 2007 a 2021, bem como apresentar a distribuição por regiões e estados de profissionais no território brasileiro. Trata-se de um estudo descritivo e de série temporal que utilizou dados secundários oriundos do sistema de consultas do Cadastro Nacional dos Estabelecimentos de Saúde (CNES). Analisou-se o quantitativo de PEF no SUS nas cinco regiões e nos vinte e seis estados e no Distrito Federal entre 2007 e 2021 e reali-zou-se a análise temporal para verificar a distribuição dos PEF nas regiões brasileiras. Os resultados apontam para um crescimento no número de PEF entre 2007 (n = 22) e 2020 (n = 7.560) em todo o país. Em 2021 observa-se uma redução de 2,8% no quantitativo de PEF. Entre as regiões, os maio-res quantitativos foram observados nas regiões Nordeste e Sudeste, enquanto nos estados a maior concentração foi em Minas Gerais, seguido de São Paulo, Pernambuco, Bahia e Rio Grande do Sul. Observou-se uma tendência crescente de PEF nas regiões Norte e Sul. Conclui-se que o quantitativo de PEF atuantes no SUS teve um crescimento expressivo durante o período analisado, sendo fruto das políticas públicas e programas voltados à promoção da atividade física constituídos ao longo do tempo. Apesar disso, há importantes disparidades geográficas que não devem ser desconsideradas, reforçando a necessidade de estratégias coletivas e investimentos em políticas públicas que fomentem a inserção dos PEF na rede assistencial e de fortalecimento do SUS

The aim of this study was to describe and analyze the time series of physical education professionals (PEF in Portuguese) in the Unified Health System (SUS in Portuguese) from 2007 to 2021, as well as to present their distribution by Brazilian regions and states. This is a time series study which used secondary data from the Consultation System of the National Registry of Health Establishments (CNES in Portuguese). We analyzed the number of PEF in the country, in the five Regions and in the twenty-six States and the Fed-eral District between 2007 and 2021 and the temporal analysis was carried out to verify the distribution of PEF in the Brazilian regions. The results point to an increase in the number of PEF between 2007 (n = 22) and 2020 (n = 7560). In 2021, there is a 2.8% reduction in the amount of PEF. Among the regions, the highest numbers were observed in the Northeast and Southeast regions, while in the states the highest con-centration was in Minas Gerais, followed by São Paulo, Pernambuco, Bahia and Rio Grande do Sul. There was an increasing trend in the distribution of PEF in the North and South regions. The number of PEF working in the SUS had an expressive growth during the analyzed period, being the result of public policies and programs aimed at promoting physical activity constituted over time. Despite this, there are important geographic disparities that should not be disregarded, reinforcing the need for collective strategies and financ-ing in public policies that encourage the insertion of PEFs in the care network and the strengthening of SUS

Effects of a ketogenic diet combined with resistance training on body composition and glucolipid metabolism in the obese and female college students / 中国学校卫生

Objective@#To investigate the effects of a ketogenic diet (KD) alone and in combination with resistance training (KD+RT) on body composition and glucolipid metabolism of obese and female college students, and to provide a theoretical basis for the application of KD+RT in obese patients.@*Methods@#Totally 45 obese and female college students in Wuyi University were recruited and randomly divided into KD group ( n =23) and KD+RT group ( n =22) in September 2021. After received training for 4 weeks, the changes of body composition and glucose and lipid metabolism of obese and female college students were compared before and after intervention.@*Results@#Both a 4 week KD and KD+RT led to decreases in weight, BMI, body fat mass, body fat percentage, waist to hip ratio, visceral fat area of obese female college students ( t =16.19, 16.21, 12.42, 7.99, 2.10, 6.37; 18.82, 18.02, 17.80, 10.72, 3.41, 7.59, P <0.01). The change of muscle mass was decreased in KD group( t=4.12, P <0.01), but there was no statistically significant difference in KD+RT group( P >0.05). Both a 4 week KD and KD+RT significantly reduced the levels of the fasting blood glucose, fasting insulin, glycosylated hemoglobin and triglyceride (TG) of obese female college students ( t =10.15, 8.94 , 6.94, 7.63; 9.23, 12.75, 9.85, 9.09, P <0.01), and increased the high density lipoprotein (HDL) level( t =-7.36, -5.22, P <0.01). However, only KD+RT group had a significant decrease in the level of LDL ( t =5.27, P <0.01), and there was no significant change in the level of TC both groups ( P >0.05). After the intervention, there was no statistically significant difference between the KD+RT group compared to the KD group ( P >0.05), except for a significant decrease in triacylglycerol ( t =2.51, P < 0.05 ).@*Conclusion@#Both a short term KD and KD+RT show beneficial changes in body composition and glucolipid metabolism in obese female college students. However, the KD+RT is superior to a KD in maintaining muscle mass and reducing the effects of lipid metabolism.

After 12 weeks of exercise intervention [The durations of load period and intermittent period were 15 s, load exercise intensity was 100% maximal aerobic speed (MAS), and intermittent exercise intensity was 50% MAS, each time there were 2 groups× 8 rounds, and the rest between groups was 2 minutes, totaling 10 minutes, and 20 meter shuttle run test (20 m-SRT) was performed once every 4 weeks to adjust and update MAS], the changes in body composition and cardio respiratory fitness indexes of obese subjects before and after the intervention were compared.@*Results@#After the intervention, body weight, BMI, body fat, body fat percentage, and visceral adipose tissue area of obese subjects in the exercise group decreased from (55.6±6.2)kg, (22.7±0.6)kg/m 2, (41.8±6.9)kg, ( 23.4± 5.5)% and (102.4±39.0)cm 2 to (52.3±5.8)kg, (21.1±0.8)kg/m 2, (38.6±6.3)kg, (20.2±4.5)% and (84.2±26.9)cm 2, respectively( t =8.73, 10.96, 7.02, 4.92, 4.95, P <0.05). SBP decreased from (115.4±9.7)mmHg to (112.3±8.7)mmHg ( t = 2.96 , P <0.05). The content of skeletal muscle, 20 m-SRT and VO 2max increased from (21.3±5.3)kg, (21.6±4.9) times and (39.4±2.0)mL/(kg ·min) to (21.8±5.2)kg, (31.4±6.3)times and (43.6±2.6)mL/(kg ·min), respectively ( t =-3.33, -8.37, -10.56 , P <0.05).@*Conclusions@#HIIT is an effective way to improve the body composition and cardiorespiratory fitness of obese primary school students. It is recommended that schools with the necessary conditions use this method as an intervention measure to help reduce weight and improve cardiovascular health among obese students.

Application of pliability training in prevention of hamstring strain injury: a review / 中华创伤杂志

Hamstring strain injury (HSI) is one of the most common injuries in athletes, which seriously reduces the mechanical properties of the muscles and affects the performance of the athletes. If not fully recovered, it will lead to secondary hamstring injuries and even permanent functional deficits. Therefore, prevention of HSI is particularly important. At present, the prevention strategies of HSI at home and abroad mainly focus on strength training, but high-intensity strength training can easily lead to muscle and joint injuries. By contrast, pliability training is a better choice for HSI prevention, for it involves stretching, joint movement and circuit training, etc, which can improve muscle extensibility, with lower intensity and higher safety than centrifugal strength training. In sports practice and clinical application, there are many problems such as inappropriate training volume, incomplete programs or poor effect, due to a lack of sufficient knowledge of pliability training in the prevention of HIS and a unified standard for training programs. For this purpose, the authors reviewed the effects of pliability training on the function and sports performance of hamstring muscles and its application in the prevention of HIS so as to provide reference for the effective prevention of HSI.

A survey on self-management level and physical activity in patients with type 2 diabetes mellitus of Zang and Han nationalities in Tibetan of China / 中国基层医药

Objective:To investigate the level of self-management and daily physical activity in patients with type 2 diabetes mellitus (T2DM) of Zang and Han nationalities in Tibetan, China, and to compare the difference in daily management between T2DM patients of Zang and Han nationalities, to develop reasonable and effective chronic disease management strategies for long-term out-of-hospital management of T2DM patients of Zang nationalities.Methods:A total of 265 T2DM patients with glycosylated hemoglobin (HbA1c) ≥ 7% who were admitted to the Endocrinology Ward of the Hospital of Chengdu Office of People's Government of Tibet Autonomous Region from November 2020 to April 2021 and who were from different regions of Tibet were included in this study according to inclusion and exclusion criteria. The general data of all included patients were collected. Glucose and lipid metabolism-related indicators were determined. The Generalized Diabetes Self-Management Efficacy Scale and International Physical Activity Questionnaires (IPAQ) were used to evaluate patients' levels of self-management and daily physical activity.Results:The hemoglobin level in T2DM patients of Zang nationality was (154.09 ± 24.11) g/L, which was significantly higher than that in T2DM patients of Han nationality ( P < 0.05). The total cholesterol, fasting blood glucose, and low-density lipoprotein in T2DM patients of Zang nationality were (4.63 ± 1.41) mmol/L, (7.94 ± 2.19) mmol/L, and (2.75 ± 1.11) mmol/L, respectively, which significantly higher compared with T2DM patients of Han nationality (all P < 0.05). Compared with T2DM patients of Han nationality, T2DM patients of Zang nationality had lower self-management scores (81.40 ± 15.44) points, diet control scores (17.26 ± 4.97) points, physical exercise scores (11.67 ± 4.42) points, prevention and treatment of high and low blood sugar score (12.21 ± 5.72) points. The differences were statistically significant (all P < 0.05). Moderate-intensity physical activity was a significant difference between T2DM patients of Zang and Han nationalities ( P < 0.05). Conclusion:Compared with T2DM patients of Han nationality, T2DM patients of Zang nationality have lower overall self-management levels, including diet control, physical exercise, prevention and management of high and low blood glucose, and moderate-intensity physical activity. Targeted individualized education should be carried out according to the Tibetan cultural characteristics, to further develop an intervention method and an out-of-hospital management strategy for chronic disease, which are suitable for T2DM patients of Zang nationality.

Effect of aerobic pedal exercise on sleep quality and energy metabolism of female college students with mild sleep disorder / 中国学校卫生

Objective@#To explore the intervention effect of aerobic step exercise on sleep quality of female college students, so as to provide a new perspective to improve the sleep quality of female college students.@*Methods@#In the 2020 fall semester, a total of 41 female college students with mild or more severe sleep disorders were selected from Beijing Normal University through a questionnaire and were randomly divided into experimental group ( n =29) and control group ( n =12). The experimental group received 55 minutes/time step aerobic exercise intervention for 8 weeks, three times a week, while the control group received no exercise intervention from October to December. The two groups maintained the original learning and living habits, without additional physical activity. The Pittsburgh Sleep Quality Index Scale and portable sleep monitor were used to assess the subjects sleep quality from both subjective and objective aspects. Changes in energy metabolism were observed by triaxial accelerometer and standing body composition analyzer.@*Results@#After exercise intervention, subjective sleep quality factor (1.24±0.43, 0.86±0.58), sleep efficiency factor (0.66±0.67, 0.07±0.25), sleep disorder factor (1.24± 0.51 , 1.03±0.18), daytime dysfunction factor (1.90±0.86, 1.48± 0.82 ) and PSQI score (7.21±1.85, 5.66±2.09) significantly improved ( t=3.64, 4.63, 2.27, 2.36, 3.29, P <0.05). The ratio of sleep to wakefulness decreased (25.54±7.86, 20.85± 5.13), the ratio of deep sleep (31.79±12.20, 38.32±10.19) and sleep efficiency (73.99±7.91, 78.68±5.12) increased significantly ( t=-2.12, -2.39, -2.21, P <0.05). Lean body mass [(38.55±2.95, 39.07±2.94)g] and basal metabolic rate [(1 257.45±41.14, 1 262.66 ±42.22)kcal] of the experimental group significantly increased after the intervention of medium high intensity aerobic pedal exercise ( F=5.95, 3.49, P <0.05). Total energy expenditure was positively correlated with subjective sleep quality and sleep efficiency ( r=-0.26, -0.44, P <0.05).@*Conclusions@#The 8 week aerobic step exercise intervention can increase the daytime energy consumption and basic metabolism of female college students. Improve the sleep depth and efficiency of female college students, reduce sleep disorders, and then effectively improve sleep quality.
