Relationship Between Physical Activity Level and Muscle Markers in a Population-Based Sample of Children and Adolescents

Objectives: The study aimed was to investigate the relationship between physical activity (PA) levels and muscle markers in healthy children and adolescents. Methods: This cross-sectional study was conducted in 2020 among school students from Isfahan, Iran. Using cluster sampling, 159 students aged 7 to 18 years were selected. In addition to the physical examination, the PA level was assessed using a valid questionnaire. The serum levels of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), creatine kinase (CK), and alanine aminotransferase (ALT) were measured. Statistical analysis was performed using the Pearson correlation test. Results: The samples included 79 girls and 80 boys with a mean age (standard deviation) of 12.72 (3.06) years and a mean body mass index of 18.30 (3.70) kg/m2. The mean AST and CPK were significantly higher in boys than in girls (P < 0.05). Participants with higher PA levels had significantly lower LDH and ALT than other participants (-0.20, P = 0.003, and 0.044 P = 0.295, respectively). There was no significant relationship between PA level and muscle enzyme levels. Conclusions: The findings of this study indicated that higher PA level was associated with lower serum muscle markers other than LDH. This suggests that the best types of PA for children and adolescents are those activities with rest sets to prevent muscle damage.

Noncommunicable Diseases (NCDs) merupakan salah satu penyebab kematian utama di dunia. Kurangnya aktivitas fisik dapat meningkatkan risiko penyakit ini. Meskipun telah banyak penelitian yang menyelidiki tentang hubungan aktivitas fisik dan faktor risiko penyakit kardiovaskuler, hanya terdapat beberapa penelitian di Indonesia yang menelaah tentang peran aktivitas fisik dalam perkembangan penyakit kardiovaskuler. Penelitian ini bertujuan untuk mendeskripsikan tentang tingkat aktivitas fisik dan menyelidiki hubungannya dengan faktor risiko penyakit kardiovaskuler pada karyawan kantor di lingkungan Universitas Sebelas Maret (UNS). Penelitian ini menggunakan desain penelitian potong lintang, dengan jumlah sampel sebanyak 44 orang. Data level aktivitas fisik diperoleh dari International Physical Activity Questionnaire (IPAQ). Sedangkan faktor-faktor risiko penyakit kardiovaskuler (gula darah, kolesterol, tekanan darah, lingkar pinggang, dan IMT) diukur dengan menggunakan alat ukur yang sesuai. Hasil penelitian menunjukkan bahwa level aktivitas fisik karyawan berkategori Rendah sebesar 6.82%, Sedang sebesar 72.73%, dan Tinggi sebesar 20.45%. Berdasarkan uji Pearson Correlation, tekanan darah baik sistolik dan diastolik mempunyai hubungan yang signifikan dengan level aktivitas fisik. Tidak ada hubungan yang signifikan antara level aktivitas fisik dengan faktor risiko lainnya dalam penelitian ini. Secara umum penelitian ini menunjukkan bahwa level aktivitas fisik karyawan di lingkungan UNS adalah berkategori sedang, dan tekanan darah mempunyai hubungan yang signifikan dengan aktivitas fisik. Physical activity level and cardiovascular risk factors among university employees AbstractNoncommunicable Diseases (NCDs) are one of the leading deaths in the world. Insufficiency of physical activity (PA) escalate the risk of NCDs. Although the reports of the studies investigating the relationship between PA and cardiovascular risk factors are abundance, only a few studies in Indonesia examined the role of PA in the development of cardiovascular diseases. The aim of this study was to describe the level of PA and investigate the relationships between PA and cardiovascular risk factors among UNS employees. This was a cross sectional study with a sample of 44 university employees. PA level was assessed using IPAQ. Meanwhile cardiovascular risk factors such as plasma glucose, cholesterol, blood pressure, waist circumference, and BMI were measured using an appropriate tool for each measure. The results revealed that participants with low level of PA (6.82%), moderate category (72.73%), and high category (20.45%). Pearson Correlation analysis showed blood pressure both systolic and diastolic had a significant association with PA level. There was no a significant association between PA level and others cardiovascular risk factors in this research. Generally, this study exhibited the level of PA among UNS employees in the moderate category, and blood pressure had a significant association with PA.

Introduction: Insufficient physical activity is one of the leading public health problems in the world, but also in Bosnia and Herzegovina. Modern civilization is characterized by a significant decrease in physical activity, and the number of people whose lifestyle can be called sedentary has never been higher, which is especially emphasised among children and adolescents. Aim of the study is to examine public health significance of physical activity on the occurrence and the degree of obesity in children and adolescents in primary and secondary schools and to determine the applicability of the Fels questionnaire on physical activity of children in rural areas of Bosnia and Herzegovina. Methods: We used a transversal research method of a cross-sectional study at a one-time point, and for obtaining results we used the Fels physical activity questionnaire for children and measurement protocol. Results: 276 primary and secondary school students in two cities participated in this survey. Respondents in Busovača are more physically active than their peers in Sarajevo. One-third of the total number of respondents is overweight and obese, and respondents in Sarajevo are significantly more nourished than their peers in Busovača. The Fels questionnaire is conditionally applicable, especially in rural areas. Conclusion: This study confirmed that the Fels questionnaire for assessing the level of physical activity for children and young people, which is the general instrument for research of physical activity in children, is too generalized because it is based on a homogeneous urban population.

The Relationship

This study investigated how perceived exercise benefit affects the relationship between cellphone usage and physical activity level. This cross-sectional study performed a survey of Taiwanese university students selected using cluster sampling. A total of 975 students were recruited (male = 367, female = 608, average age = 20.10 ± 1.42). Data were analyzed using descriptive statistics, correlation analysis, and hierarchical regression. The results show that cellphone usage was negatively correlated with physical activity level, whereas perceived exercise benefit was negatively correlated with cellphone usage and positively correlated with physical activity level. In hierarchical regression, the main effects of cellphone usage and perceived exercise benefit explained 22% of the variance in physical activity level. After controlling for the main effect, the interaction term accounted for an additional 1% of the variance. Cellphone usage and perceived exercise benefit thus had significant power to explain physical activity level. The results of this study reveal a novel phenomenon—that students who perceived the benefits of exercise to be greater are more physically active.

Background Previous research studies have demonstrated a relationship between low levels of physical activity and high amounts of screen time in children and adolescents. However, this is usually based on self-reported data. Therefore, the aim of this cross-sectional study was to investigate the association between objectively measured smartphone screen time and physical activity among children and adolescents aged 10–15 years. Methods During seven consecutive days, we objectively assessed smartphone screen time, using the SCRIIN smartphone application, and physical activity, using the SCRIIN activity tracker, in children and adolescents recruited from two schools in Stockholm County, Sweden. Moreover, the children/adolescents and their parents responded to a questionnaire, obtaining among other things: self-reported screen time, physical activity, sleep and health-related quality of life. Results A total of 121 children and adolescents (mean age: 12.1 ± 1.5) were included in the study. Objectively measured smartphone screen time was 161.2 ± 81.1 min/day. Mean physical activity, measured with the SCRIIN activity tracker, was 32.6 ± 16.5 active min/day. Minutes of screen time and physical activity did not differ between the children and adolescents from the two schools, despite located in different socioeconomic areas. Further, we found no association between smartphone screen time and physical activity. However, girls aged 14–15 years, had more smartphone screen time (p<0.01) and were significantly more physically active (p<0.01) than girls aged 10–12 years. In addition, boys reported more than five times more time spent on computer and video games than girls did. Conclusion Smartphone screen time was not associated with physical activity level among children and adolescents aged 10–15 years.

Abstract Background : people with Cystic Fibrosis (CF) have progressive limitation to physical exercise and reduced daily living activities. Regular physical activity (PA) and exercise contribute to the quality of live of people with CF. The objective of this study was to evaluate level of PA , lung function and functional capacity in children and adolescents diagnosed with CF and compare them with those of healthy children and adolescents. Methodology: the study had a cross-sectional design with a control group. Patients with CF were followed at the Children’s Pneumology Outpatient Clinic, and were matched for age and sex with healthy controls from a local public school. The evaluations included daily step count, the shuttle walk test and spirometry. Results: 70 children and adolescents were evaluated, 35 diagnosed with CF and 35 healthy controls. The overall mean age was 11.6±2.9 years. There was no significant difference in level of PA between the patient and control groups. Gender analysis revealed no significant difference in level of PA between the groups or within the CF group. The CF group values were significantly lower than the control group for BMI (p=0.04), percentage of predicted FEV 1 and FEV 1 Z-score (p=0.02 and p=0.010). Conclusion: In this sample, children and adolescents with CF had the same level of PA as their healthy peers. Boys and girls with CF had similar level of PA when stratified by sex, as well as when compared to healthy peers of the same gender. Differences were observed between BMI, FEV 1 and some functional capacity test variables between the groups.

Background:This study was carried out to assess physical activity level and identify associated factors among higher secondary school students in Banke district, Nepal.Methods:A school-based, cross-sectional descriptive study was conducted among 405 students studying in grades 11 and 12 in 7 higher secondary schools selected randomly. A self-administered questionnaire based on the International Physical Activity Questionnaire was used to measure physical activity level.Results:Only 5% of students were found to be inactive, and domestic and transport-related activities were major contributors to total physical activity score. No significant difference existed for total physical activity and domain-specific and activity-specific scores across different age groups when males and females were tested separately. Being male (P = .046), lower economic status (P = .026), living at a distance of less than 30 minutes (P = .007), walking/cycling to school (P < .001), and studying in government school (P < .001) were associated with increased physical activity scores on multivariate logistic regression analysis.Conclusion:Routine activities such as transport and household chores contributed greatly to total physical activity among students. This study highlights the need for physical activity promotion interventions at school addressing the associated factors and a need for greater focus on leisure-time physical activities.

Daily Work

Background: Productivity is the ability to produce goods and services using resources efficiently. Low worker productivity can affect the ability and results of their work. Work productivity can be influenced by various things, one of which is energy intake and physical activity of the workforce.Objective: To analyze the correlation between energy intake and physical activity level with productivity in workers with overweight nutritional status.Method: this research was observational analytic with design study cross sectional. The population were 30 workers with overweight. 22 samples were chosen by simple random sampling. Energy intake data was obtained through 24-hour food recall questionnaire within 2 days (weekend and weekdays). Physical activity data were obtained through the Baecke questionnaire. Productivity data obtained from reporting the results of daily work. Statistical analysis using Pearson correlation test and chi square.Results: 23% of respondent was overweight, 50% of respondent was obesity 1 and 27% of respondent was obesity 2. The average energy intake of respondents was 2330.5 ± 853 kcal and the average index of physical activity of respondents was 7 , 5 ± 1.59. Based on the analysis of the data there was a relationship between energy intake and productivity (p = 0.001). There was not relathionship between physical activity and productivity (p = 0.129).Conclusion: workers who have higher energy intake have better productivity. Therefore, labor energy intake needs to be considered. One form of regulating energy intake is to provide food according to energy needs for workers in the company. These efforts can be done by providing food or by providing food as needed in the company canteen. ABSTRAK Latar Belakang: Produktivitas adalah kemampuan untuk menghasilkan barang dan jasa dengan memanfaatkan sumber daya yang dimiliki secara efisien. Tenaga kerja dengan produktivitas yang rendah dapat berpengaruh pada kemampuan dan hasil kerjanya. Produktivitas kerja dapat dipengaruhi oleh berbagai hal salah satunya yaitu asupan energi dan aktivitas fisik tenaga kerja. Kondisi gizi lebih yang dialami oleh tenaga kerja akan berpengaruh pada kondisi kesehatan dan kemampuan mobilitas sehingga dapat mempengaruhi kemampuan kerja dan produktivitas.Tujuan: Menganalisis hubungan asupan energi dan tingkat aktivitas fisik dengan produktivitas pada tenaga kerja berstatus gizi lebih.Metode: Penelitian ini merupakan penelitian observasional analitik dengan desain penelitian Cross sectional. Besar sampel sebanyak 22 orang dipilih secara simple random sampling. Data asupan energi didapatkan melalui kuesioner foodrecall 2x24 jam. Data aktivitas fisik didapatkan melalui kuesioner Baecke. Data produktivitas didapatkan dari pelaporan hasil kerja harian. Analisis statistik menggunakan uji korelasi pearson.Hasil: Sebanyak 23% responden memiliki status gizi overweight,50% responden memiliki status gizi obesitas 1, dan 27% responden memiliki status gizi obesitas 2. Rata-rata asupan energi responden sebesar 2330,5±853 kkal dan rata-rata indeks aktivitas fisik responden 7,5±1,59. Berdasarkan analisis data diketahui bahwa terdapat hubungan antara asupan energi dengan produktivitas (p=0,001 dan r=0,660) terutama pada responden laki-laki (p=0,020 dan r=0,716). Aktivitas fisik tidak berhubungan dengan produktivitas (p=0,131).Kesimpulan: Tenaga kerja yang memiliki asupan energi lebih tinggi memiliki produktivitas yang lebih baik terutama pada tenaga kerja laki-laki. Salah satu bentuk upaya perbaikan produktivitas kerja yaitu dengan menyediakan makanan sesuai kebutuhan energi bagi tenaga kerja di perusahaan. Upaya tersebut dapat dilakukan dengan menyelenggarakan pemberian makanan ataupun dengan menyediakan makanan sesuai kebutuhan di koperasi perusahaan.

Focus Theory

BACKGROUND There have been challenges in designing effective behaviour-change interventions, including those that promote physical activity. One of the key reasons is that many of those systems do not account for individuals’ characteristics and their psychological differences, which affect their approach toward adopting target behaviour. For decades, tailoring has been used as a common technique to effectively communicate health-related information to persuade people to follow a healthier living. However, its use in the design of persuasive technologies has not been adequately investigated. OBJECTIVE The objective of this research is to explore the effects of tailoring when it is grounded in Higgins’ regulatory focus theory. METHODS A combination of cross-sectional and longitudinal studies has been proposed to examine how individuals’ intention to become more physically active would be affected by receiving health messages that may or may not match their self-regulatory orientation. The research would also subjectively, as well as objectively, measures the changes in individuals’ physical activity level. RESULTS The anticipated completion date for the consequent studies is December 2016. CONCLUSIONS In this article, the importance of refining message-framing research questions and a stepwise approach to develop an efficient experimental design to examine a new tailoring strategy is discussed. A set of small studies is proposed that would inform the best approach to design the principal experiment. The findings of principal experiment will provide a deeper insight into the relationship between regulatory-focus theory, persuasive message construction, and individuals’ physical activity behaviour.
