Quantitative assessment of multichannel intraluminal impedance pH and its clinical implications
Authors: Koo Eden , Clarke John O. , Yang Boli , Pasricha Pankaj J. , Zhang Nina
Published: February 2022

We sought to quantify the characteristics of acid reflux episodes in patients with extraesophageal GERD symptoms (EES), hiatal hernia (HH), and erosive esophagitis (EroE) using multichannel intraluminal impedance pH (MII‐pH) and investigate the correlation between impedance parameters and high resolution esophageal manometry (HREM). This was a retrospective analysis of esophageal manometric and impedance data inpatients with typical GERD symptoms who underwent both HREM and 24 h MII‐pH tests. Within the three patient subgroups, we evaluated impedance metrics such as average height of reflux, total duration of reflux, maximum duration of reflux, average pH, and average area of reflux. We also introduce a novel composite reflux index (CRI) metric, which is a measure of reflux height, duration, and acidity. Patients with EES exhibited a 29.3% increase in average height of reflux, compared to non‐EES patients (p < 0.01); the average height of reflux was found to be an independent predictor of EES (p < 0.01). Patients with HH showed a 190% longer total reflux duration (p < 0.01, vs. non‐HH patients). Total reflux duration was twice as long in EroE patients compared to those without (p = 0.02). Average CRI was significantly different within all three subgroup comparisons (p < 0.01). Impedance metrics shared weak negative correlations with lower esophageal sphincter (LES) rest pressure and distal contractile integral (DCI), and weak positive correlations with % absent peristalsis (p < 0.05 to p < 0.01 for various parameters). Quantitative impedance metrics provide useful insight into the pathophysiology of reflux in patients with EES, HH, and EroE.
Los errores en las pruebas de cabecera pueden resultar en falsos niveles de potasio
Authors: Soto Antonio Buño , Sáez Paloma Oliver
Published: February 2022

Las pruebas de cabecera (POCT, por sus siglas en inglés) permiten disponer de los resultados en un corto espacio de tiempo, facilitando la toma rápida de decisiones médicas. Sus resultados deben ser fiables, y su calidad no debe verse comprometida durante el proceso. Las gasometrías son una de las pruebas POCT más utilizadas en los servicios de urgencias y cuidados intensivos. Se suele utilizar sangre entera como muestra, debiendo tener en cuenta el riesgo de hemólisis. Sin embargo, los analizadores empleados para las gasometrías POCT no detectan la presencia de hemólisis en la muestra y, debido a las características de la misma, tampoco se puede identificar la hemólisis a simple vista. La hemólisis puede alterar el resultado de parámetros como el potasio, mostrando resultados anormalmente elevados o concentraciones normales, enmascarando niveles que, en realidad, son bajos (hipopotasemia). La hiperpotasemia está asociada a un mayor riesgo de sufrir arritmia potencialmente fatal, y requiere de una actuación médica urgente. La hemólisis es la causa más frecuente de pseudohiperpotasemia (hiperpotasemia espuria) o pseudonormopotasemia, lo que puede llevar a un diagnóstico erróneo y a la consiguiente toma de decisiones clínicas inadecuadas. En el presente artículo, realizamos una revisión completa de los posibles factores que pueden hacer que una prueba POCT informe un resultado falso de concentraciones elevadas de potasio en sangre. Los programas de POCT adecuadamente supervisados y organizados por el laboratorio clínico pueden contribuir a prevenir errores y reducir su impacto en el manejo del paciente.
Management Turnover, Strategic Ambiguity and Supply Incentives
Authors: Pasquier Nicolas , Toquebeuf Pascal
Published: February 2022

When a firm appoints a new manager, it reopens the possibility of new contractual friction with its partners. We explore strategic ambiguity as a potential for friction with a supplier. The firm’s new manager probably has fuzzy expectations about the supplier’s strategy. An optimistic manager weights favorable strategies more heavily than detrimental ones, whereas a pessimistic manager does the opposite. We show that the manager’s degree of optimism is critical: above a threshold, it can cause the supplier to change the timing of its contracting and increase its profits. We also find that this threshold degree of optimism depends on the degree of product substitution: it is more stringent with imperfect substitutes than with perfect substitutes or unrelated goods.
Self-Regulation Predicts Mental Health and Well-Being During the Covid-19 Pandemic: A Prospective Study
Authors: Haydon Katherine C. , Salvatore Jessica E.
Published: February 2022

Introduction: As evidence of the psychological effects of the COVID-19 pandemic emerge, examining the role of self-regulation may yield key insights. This prospective study tested whether pre-pandemic self-regulation was associated with mental health, well-being, and substance use during the initial COVID-19 surge. Methods: Participants (N = 236; Mage= 30.3; 64% female) were assessed 1–3 years prior to the pandemic and again in April of 2020. Markers of self-regulation (vagal tone, attachment insecurity, stress-reactive rumination, and attentional control) were assessed at Time 1, as were depressive symptoms, sleep problems, relationship satisfaction, perceived stress, and substance use. These outcomes were assessed again during the pandemic, along with anxiety symptoms and peri-traumatic distress. Results: Poor pre-pandemic self-regulation was associated with higher peri-pandemic depressive and anxiety symptoms, peri-traumatic distress, and cannabis use. Self-regulation was not associated with sleep, relationship satisfaction, alcohol use, or drug use and did not moderate changes over time. Discussion: Prospective analyses indicated simultaneous, independent associations of cognitive and emotional self-regulation with mental health and well-being during the initial COVID-19 pandemic surge, yet pre-pandemic self-regulation did not account for trajectories of change over time. Findings emphasize the importance of prospective data for understanding biopsychosocial resilience during the pandemic and beyond.
Narrative Therapy and Mindfulness: Intention, Attention, Ethics. Part 2
Authors: Percy Ian , Paré David
Published: February 2022

This is the second of a matched pair of articles that present concepts and practices for expanding the territory of narrative therapy to include working with attention and present moment awareness. The first article explored similarities and differences between narrative therapy and attentional practices derived from Buddhist traditions frequently associated in western contexts with the term “mindfulness.” That piece proposed that both narrative and mindfulness support persons in enacting ethical choice, but the process differs in the two traditions. Narrative is preoccupied with stories or discourses, which are externalized, making space for the performance of alternatives. Mindfulness practices key in on attention, supporting persons in relinquishing the grasp on a never-ending flow of mental phenomena. Narrative seeks to liberate our storying capacity; mindfulness seeks to liberate our attention. Both traditions support persons in living in a manner congruent with their values; we have called this ethical intentionality. This companion article offers examples of how these two traditions can be co-mingled in therapeutic practice.
Instrumentarium zarządzającego programem rozwoju przywództwa: mierniki sukcesu
Authors:   Uniwersytet  Warszawski, Majczyk Julita
Published: February 2022

Theoretical and empirical evidence citing research on leadership development is scarce, as is awareness of the effects of leadership training. Moreover, these programs remain largely ineffective in tapping the optimal leadership potential of employees. Hence, this study aims to identify and describe the effects of investments in leadership development programs and to provide insight into methods for quantifying these benefits regardless of the specialization or location of a large company. Participants were selected purposefully. The core part of the qualitative study was conducting 26 individual semi-structured interviews. The analysis of the data was based on grounded theory procedures. The data indicates that while teaching the practice of leadership behavior generates a variety of benefits, these benefits can sometimes go unnoticed by managers. Meanwhile, a distinction can be made between non-leadership and leadership benefits of leadership training. Leadership benefits relate to the development of individual participants of the program, as well as translate into relationships and the quality and quantity of work performed. In addition, the managers of these programs, except in individual cases, do not measure and analyze the effectiveness of training effects in a standardized manner, which may effectively limit the development of the category of benefits from investment in the leadership development of an individual employee or the potential of these programs, or make it impossible to indicate the direction and scope of improvements necessary to maintain or improve their effectiveness.

Authors: Ostrowski Adam
Published: February 2022

The implementation of the HMI (Human-Machine Interface) operator panel on the production line is a new stage of the digital transformation of a paints and varnishes manufacturer in the SMEs sector. As part of an innovation plan, the process of production data acquisition was restructured, by means of IT (Information Technology), into an ERP (Enterprise Resource Planning) system. The introduction of an HMI panel made it possible to digitalize data acquisition and operation reporting to the ERP system. The digital transformation of the SME 4.0 company was modelled on the Industry 4.0 trend solutions. The specialized model, developed according to RAMI 4.0 (Reference Architecture Model Industry 4.0), effected change of a partial and local nature in the enterprise. The data is now entered directly into the production area by the employees on the technological line, once they have logged in to the ERP system. Access to digital production data obtained from a SSOT (single source of truth) benefited all those who used the ERP system. A postimplementation analysis of a two-year application of the restructured data acquisition process indicates the business areas which profit from digital operational data acquisition and higher quality production reporting.

Published: February 2022

Education and technology have been tailed by some conditions. Some parts in education are technologized including peer feedback activity, but the use of peer feedback combined with e-learning needs to be reviewed in terms of its practical use. The affordance of technology has enabled peer feedback to take place online. Despite the potential benefits that online peer feedback may offer, there is a lack of studies on the topic. Therefore, this paper aims to explore students’ perspectives on the benefits of online peer feedback. This research was done qualitatively. Interview to six students of English Language Education Department was conducted to gain the data. The academic year 2018/2019. In selecting the participants, purposive sampling was applied. The finding of this study revealed that the use of technology particularly in giving peer feedback brought some benefits e.g., increasing students’ autonomy and reviving student’s critical thinking. Besides, the cons of this phenomenon were that students felt the activity ruined their energy to stay focused in front of the screen to give others a review. Some suggestions in the last part of this paper also appeared as the researchers respond to this phenomenon.

Teachers’ conceptions of English assessment in International Baccalaureate Curriculum – Secondary Level
Authors: Maryono Geby Devtiana , Purnawarman Pupung , Sukyadi Didi
Published: February 2022

Assessment as an essential part of teaching and learning might be perceived differently by teachers, whereas teachers' conception of assessment influences strategies and implementation of assessment. The International Baccalaureate curriculum is one of the international curricula widely used with its own assessment principles and implementation. This research aims to explore how teachers in IB secondary schools perceive English assessment in IB curriculum.  By implementing a mixed-method approach, six teachers from five different IB secondary schools and two teachers from one IB secondary school participated in the questionnaire and interview. From the data, this research revealed that teachers perceive English assessment in IB curriculum as a valid and reliable means to improve teaching and learning, school accountability, and student accountability. The teachers also believe IB curriculum objectives have been well embedded in the English assessment process. Although the teachers have a positive perception of the assessment process in IB curriculum, several challenges are found, primarily in giving an authentic and personalized assessment. To solve the challenges, the teachers collaborate and share about the assessment practices they conducted in classes. Further research can be done to explore the perception of English assessment in IB curriculum from the students' point of view.
srGAP2 deactivates RhoA to control the duration of thrombin-mediated endothelial permeability
Authors: Lopez Rioja Alba , Faulkner Ashton , Mellor Harry
Published: February 2022

The endothelial barrier is a tightly regulated gateway in the transport of material between circulation and the tissues. Inflammatory mediators such as thrombin are able to open paracellular spaces in the endothelial monolayer to allow the extravasation of plasma proteins and leukocytes. Here we show that the protein SLIT-ROBO Rho GTPase-activating protein 2 (srGAP2) plays a critical role in regulating the extent of thrombin-mediated opening. We show that srGAP2 is not required for normal barrier function in resting endothelial cells, but that depletion of srGAP2 significantly increases the magnitude and duration of junctional opening in response to thrombin. We show that srGAP2 acts to switch off RhoA signaling after the contraction phase of thrombin-induced permeability, allowing respreading of cells and reformation of the barrier. srGAP2 is also required for effective restoration of the barrier after treatment with two other vasoactive agents that active RhoA – TNFα and angiotensin II. Taken together, we show that srGAP2 has a general function in controlling RhoA signaling in endothelial permeability, acting to limit the degree and duration of opening, by triggering the switch from endothelial cell contraction to respreading.

Conversations on Diagnostic Uncertainty and Its Management Among Pediatric Acute Care Physicians
Authors: Patel Shivani J. , Ipsaro Anna , Brady Patrick W.
Published: February 2022

OBJECTIVE

Diagnosis is a complex, iterative, and nonlinear process, often occurring over time. When presenting signs, symptoms, and diagnostic testing cannot be integrated into a diagnosis, clinicians are confronted with diagnostic uncertainty. Our aim was to study the self-reported cognitive, communication, and management behaviors of pediatric emergency medicine (PEM) and pediatric hospital medicine (PHM) physicians regarding diagnostic uncertainty.

METHODS

A qualitative study was conducted through focus groups with PEM and PHM physicians in a large academic pediatric medical center. Four focus groups were conducted. Interviews were recorded, deidentified, and transcribed by a team member. Thematic analysis was used to review the transcripts, highlight ideas, and organize ideas into themes.

RESULTS

Themes were categorized using the model of the diagnostic process from the National Academy of Sciences. “Red flags” and “gut feelings” were prominent during the information, integration, and interpretation phases. To combat diagnostic uncertainty, physicians employed strategies such as “the diagnostic pause” and having a set of “fresh eyes” to review the data. It was important to all clinicians to rule out any “cannot miss” diagnoses. Interphysician communication was direct; communication with patient and families about uncertainty was less direct because of physician concern of being thought of as untrustworthy. Contingency planning, “disposition over diagnosis” by ensuring patient safety, the “test of time,” and availability of resources were techniques used by physicians to manage diagnostic uncertainty.

CONCLUSIONS

Physicians shared common mitigation strategies, which included consulting colleagues and targeting cannot miss diagnoses, but gaps remain regarding communicating diagnostic uncertainty to families.

Professional burnout syndrome is undoubtedly another civilisation disease that affects modern societies. In May 2021 professional burnout was included within the list of the WHO International Classification of Diseases, however, not as a disease, but as an occupational syndrome significantly affecting health of an employee. However, it is worth noting that it is only from 2022 that professional burnout will have become a disease which will need to be treated. The research presented below shows that there are many factors which cause this new disease, and stress is among the main ones. Working as a teacher, which is considered one of the professions of supportive nature, means being exposed to various stress factors. One of the most dangerous effects is professional burnout which can lead, among others, to many health disorders, subjective treatment of students, and ultimately, make teachers resign from their job.

Matters of the Danube Bulgars Identity and the Historical Ancestors of Chuvash in the Studies of Arist Kunik
Authors:   Peter the Great Museum of Anthropology and Ethnography (The Kunstkamera) of the Russian Academy of Sciences, Salmin Anton
Published: February 2022

Introduction. Academic of the Imperial Academy of Sciences of Saint Petersburg Arist Kunik published his work “On the Relationship of Hagan-Bulgarians with the Chuvash According to the Slavic-Bulgarian Nominalia” in 1878. The matters of the historical relationship of Bulgarians and Chuvash have been widely discussed since that time. The objective of the article is to evaluate the basic provisions of Kunik’s study from the point of view of innovative advances in this field. Attention is focused on the identity of Danube Bulgars and the historical ancestors of modern Chuvash. Methods and materials. Kunik based his reasoning on two books of Andrey Popov with the review of chronicles in the Russian version. Such chronicles are consolidated in scientific literature under the conventional name ‘Nominalia’. Kunik also used the opinions of Vasily Radlov. Analysis. Matters of the Danube Bulgars ethnogenesis enter largely into Kunik’s work. Given the fact that the Bulgars had come from the Caucasus and then divided into descents in the Volga and the Danube regions, Kunik resorts to comparative characteristics of the Danube and Volga historical ancestors of the Bulgars. In the Middle Volga region, the Bulgars appeared in the 8th – 9th centuries. This is evidenced by the archeological monuments of the saltov type. Bulgarian researchers find direct correspondence between the Kubrat and Asparuhovo Bulgarians. Results. Kunik says that the Chuvash are direct descendants of Bulgars. However, his views on this matter are quite unreliable. His doubts were dispelled in the 20th – 21st centuries by the historical science. In spite of the ambiguity of a lot of Kunik’s provisions on the identity of Danube Bulgars and the Chuvash, now his suppositions are confirmed to a great extent – primarily, by linguists. Generally Kunik based his research on the names of Bulgarian khans and numeral adjectives in the Nominalia.
Development of Political, Economic and Cultural Relations Between Arab Countries and Bulgaria (The End of the 19th – 20 th Centuries)
Authors:   Kuban State University, Vartanyan Egnara
Published: February 2022

Introduction. The article is devoted to the development of relations between Bulgaria and the Arab countries in the nineteenth and twentieth centuries. The development of relations between Bulgaria and the countries of the Arab East is of interest in the context of the study of the forms, directions of cooperation, reasons for the mutual interest of peoples heterogeneous in ethno-confessional and cultural terms. Methods and materials. The historical-typological, historical-systemic methods and the civilizational approach used in the article allow to analyze the process of the emergence, development and transformation of the Bulgarian-Arab relations in political, trade, economic, cultural areas. Analysis. Before World War II the international mechanisms were being created for the further development of trade, economic, and political ties between the Arab states and Bulgaria together with infrastructure and sea transport routes. The problems in the development of Bulgarian-Arab relations were caused by the difficulties in forecasting of the processes, which were often subordinate to the subjective factor, personal ambitions and emotions of Arab leaders. Bulgarian diplomacy demonstrated the great patience to maintain relations that met the country’s interests. The cooperation between Bulgaria and the Arab countries developed in various forms with noticeable positive dynamics. Political changes in a number of Arab countries and inter-Arab conflicts did not fundamentally affect relations, but caused only temporary difficulties. Despite the fact that the systemic changes, which occurred in Bulgaria in the 1990s, became a restraining factor in the development of the Bulgarian-Arab relations, they were restored due to the mutual interests of the states at the turn of the 20th – 21st centuries. Results. It is concluded that Bulgaria had established diplomatic relations with almost all Arab countries by 1960. The main direction of development of ties until the 1990s was dictated by political and ideological considerations, but trade and economic relations often preceded political ones. Bulgaria had gone beyond the traditional exchange of goods and switched to such forms of cooperation as construction, engineering design, tourism, culture, exchange of specialists, and personnel training. At the end of the 20th century Bulgarian leadership returned to the development of relations with Arab countries, which was dictated by the needs of the market economy development, new political realities and Bulgaria’s attempts to identify its place in the modern world.

In the study reported on here we examined the relationship between irrational beliefs and stress levels among orphans in public secondary schools in Kenya. Rational Emotive Behaviour Theory was adopted. In the study we adopted a cross-sectional correlation research design. A sample size of 350 double orphaned students in secondary schools was obtained using stratified and simple random sampling techniques. The Irrational Belief Inventory and Perceived Stress Scale were used to collect data. The reliability results indicate the Cronbach’s alpha values ranging from 0.672 to 0.756. Quantitative data from questionnaires were analysed using inferential statistics such as Pearson correlation and regression analysis. The findings established a weak positive (n = 314, r = .149; p = .008 < .05) Pearson product-moment correlation coefficient between demandingness and stress levels; a weak positive (n =314, r = .243; p < .05) correlation between awfulizing and stress levels; a weak positive (n = 314, r = .191; p < .05) correlation between irrational belief for low frustration tolerance and stress levels; and a weak positive (n = 314, r = .167; p = .003) correlation between irrational belief of worthlessness and stress levels. The implication of these findings is that orphaned students are overwhelmed with stress because of their state of irrational beliefs. It is recommended that school counsellors should train orphans in secondary schools on rational beliefs through therapy techniques such as positive self-talk to counter the irrational beliefs.
Design and construction of a new stress-ribbon pedestrian bridge in the Italian Alps
Authors: Lorenzi Andrea , Moser Stefano
Published: February 2022

A new stress-ribbon pedestrian bridge has been built over a 60 m deep part of the Gander River valley in the Italian Alps. Completed in 2021, the 118 m long structure now provides a safer and more direct link between the mountain villages of Barbiano and Saubach. It is the longest stress-ribbon bridge in Italy and one of the longest in Europe. This paper describes the complex non-linear design, construction and load-testing of the attractive low-impact structure. It concludes that with sufficiently competent designers and contractors, stress-ribbon pedestrian bridges have a potentially wide application.

This paper presents the results of an experimental study that investigated changes in the mechanical properties of two types of concrete under normal and extreme loading conditions pre- and post-carbonation. Specimens of CEM I and CEM II concrete (concrete prepared with 20% replacement cement with pulverised-fuel ash) were cured for 28 days before accelerated carbonation under 4% carbon dioxide (CO2) for 28 days at 20°C and 57% relative humidity. Static compressive mechanical tests at ambient temperature were carried out for both concrete types. For CEM I concrete, static compressive mechanical tests were performed at elevated temperatures of 300, 500 and 650°C, and high-strain-rate tests were performed at ambient temperature and elevated temperature of 500°C. The results show that the mechanical performance of CEM I concrete was improved after carbonation – that is, static compressive strength increased at ambient and elevated temperatures, and the dynamic strength was higher than that of fresh concrete at the same strain rate at both ambient and elevated temperatures. However, CEM II concrete suffered reductions in compressive strength after carbonation.

Background: Magnolia alejandrae is a critically endangered species and endemic to the Sierra Madre Oriental in northeastern Mexico. The abiotic requirements for its germination, such as light and temperature, are unknown. Hypotheses: White light and temperature fluctuations will promote the germination of M . alejandrae and seeds from site with higher humidity will have increased germination percentage. Study species: Magnolia alejandrae . Study sites and dates: El Farallón in the Jaumave municipality and Los San Pedros in the Güémez municipality, Tamaulipas, Mexico. May-June 2019. Methods: Four light-quality treatments (white, red, far-red and darkness) were evaluated, along with two temperature treatments: constant (18/18 ºC) and fluctuating temperatures (8/18 ºC) and two populations (El Farallón and Los San Pedros) on the germination of M . alejandrae . We used twenty seeds of the study species per experimental unit with five repetitions for each treatment. Results: Light quality influenced the germination of M . alejandrae seeds, having the highest germination (76 %) under white light, followed by 45 % under red light, 9 % under far-red and 5 % in darkness, demonstrating that the seeds of this species are neutral photoblastic. Temperature fluctuation (8/18 °C) enhanced germination of M . alejandrae more than constant temperature (18/18 °C). Conclusions: M . alejandrae seeds respond differentially to light quality and temperature, which has important implications in the reforestation and conservation of the species.

Hepatitis B and C among health care workers – Analysis of a 25-year time trend Aim: We describe the development of occupational diseases related to hepatitis B (HB) and hepatitis C (HC) in Germany from 1996 to 2020. At the same time we examine which occupational groups and sectors are particularly affected. Methods: We analysed routine data from the social accident insurance provider for the health and welfare sector (BGW). The number of recognised occupational diseases is presented, separated according to profession and sector. Results: A total of 2,120 occupational diseases due to HB or HC were recognised over the past 25 years. HC cases were more common than HB cases. Women were more frequently affected than men (76.9 % vs. 23.1 %). Health care workers/nurses and hospitals accounted for the largest number of cases by profession and sector (38.3 % and 44.2 % respectively). From 1996 to 2000 the number of recognised cases was 692, and from 2016 to 2020 it was 99. This equates to a reduction of 85.7 %. Nurses and hospitals respectively benefited the most from this reduction. Conclusions: The number of cases of transfusion-transmissible viral hepatitis is declining, which can probably be explained by improved preventative measures and protection in the workplace. However, the fact that 20 HB- or HC-related occupational diseases have occurred on average over the last five years should act as an incentive to further optimise the protection of employees. Keywords: hepatitis – occupational disease – health care worker – trend over time

Bu araştırmanın amacı, master atletlerin yarışma öncesi gönüllü besin kısıtlamalarını, besin tercihlerini ve besinlerden kaçınma nedenlerini belirlemektir. Araştırmaya 5 km, 6-10 km, 11-21 km, maraton ve ultra maraton mesafelerinde antrenman ve yarışmalara katılan, yaşları 35-74 arasında olan toplam 246 master atlet (185 erkek, 61 kadın) katılmıştır. Atletlerin besin kısıtlamalarına yönelik yaptıkları uygulamaları belirlemek için Parnell ve arkadaşları (2019) tarafından geliştirilen 17 soruluk “Koşucularda Besin Kısıtlaması Anketi” kullanılmıştır. Veri toplama süreci, Covid-19 pandemi döneminde gerçekleştirildiğinden verilerin bazılarına yüz yüze görüşülerek bazılarına ise online olarak ulaşılmıştır. Yarışma öncesinde kaçınılan besinlerin; cinsiyet, koşu mesafesi ve performans seviyesi grupları arasındaki farklılıklarını belirlemek için Fisher Exact testi kullanılmıştır. Tüm istatistiksel analizlerde anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Yarışma öncesi en çok kısıtlanan besinlerin yüksek yağlı yiyecekler (%79), atıştırmalık hazır paket ürünleri (%63), baharatlı yiyecekler (%58), süt (%54) ve kırmızı et (%44) olduğu belirlenmiştir. Kurubaklagil, süt ve yüksek lifli gıdaların kısıtlanmasında cinsiyetler arası anlamlı bir ilişki olduğu ve kadınlarda kısıtlamanın daha fazla olduğu belirlenmiştir (p<0,05). Özellikle yüksek yağlı yiyecekler ve laktozsuz sütün koşu mesafesi arttıkça ve performans seviyesi yükseldikçe daha fazla kısıtlandığı belirlenmiştir (p<0,05). Kadın master atletlerde yarışma öncesi besin kısıtlama uygulamasının daha yüksek oranda görüldüğü ve koşu mesafesinin artması ile performans seviyesinin yükselmesinin, master atletlerde besin kısıtlama oranlarını artırdığı belirlenmiştir.
