Validation of a novel device to measure and provide feedback on sedentary behavior

Purpose. Pedometers, which enable self-monitoring of step counts, are effective in facilitating increases in physical activity. Similar devices which provide real-time feedback on sedentary (sitting) behavior are limited. This study aimed to develop and validate a novel device – the SitFIT – which could accurately measure and provide feedback on sedentary behavior and physical activity. Methods. The SitFIT is a tri-axial accelerometer, developed by PAL Technologies, which is worn in the front trouser pocket. This enables tracking of thigh inclination and therefore differentiation between sitting and upright postures, as well as tracking of step count. It has a display to provide user feedback. To determine the validity of the SitFIT for measuring sedentary behavior and step counts, 21 men, aged 30-65 years, with body mass index 26.6±3.9 kg.m-2 wore a SitFIT in a front trouser pocket and an activPAL accelerometer attached to their thigh for up to seven days. Outputs from the SitFIT were compared with the activPAL, which was assumed to provide gold-standard measurements of sitting and step counts. Results. Mean step counts were ~4% lower with the SitFIT than activPAL, with correlation between the two methods being very high (r=0.98) and no obvious bias from the line of equality (regression line: y=1.0035x+418.35). Mean sedentary time was ~5% higher with the SitFIT than activPAL, correlation between methods was high (r=0.84) and the equation of the regression line was close to the line of equality (y=0.8728x+38.445). Conclusions. The SitFIT has excellent validity for measurement of free-living step counts and sedentary time and therefore addresses a clear need for a device that can be used as a tool to provide feedback on sedentary behavior to facilitate behavior change

Study protocol of European Fans in Training (EuroFIT):a four-country randomised controlled trial of a lifestyle program for men delivered in elite football clubs

Background: Lifestyle interventions targeting physical activity, sedentary time and dietary behaviours have the potential to initiate and support behavioural change and result in public health gain. Although men have often been reluctant to engage in such lifestyle programs, many are at high risk of several chronic conditions. We have developed an evidence and theory-based, gender sensitised, health and lifestyle program (European Fans in Training (EuroFIT)), which is designed to attract men through the loyalty they feel to the football club they support. This paper describes the study protocol to evaluate the effectiveness and cost-effectiveness of the EuroFIT program in supporting men to improve their level of physical activity and reduce sedentary behaviour over 12 months. Methods: The EuroFIT study is a pragmatic, two-arm, randomised controlled trial conducted in 15 football clubs in the Netherlands, Norway, Portugal and the UK (England). One-thousand men, aged 30 to 65 years, with a self-reported Body Mass Index (BMI) ≥27 kg/m2 will be recruited and individually randomised. The primary outcomes are objectively-assessed changes in total physical activity (steps per day) and total sedentary time (minutes per day) at 12 months after baseline assessment. Secondary outcomes are weight, BMI, waist circumference, resting systolic and diastolic blood pressure, cardio-metabolic blood biomarkers, food intake, self-reported physical activity and sedentary time, wellbeing, self-esteem, vitality and quality of life. Cost-effectiveness will be assessed and a process evaluation conducted. The EuroFIT program will be delivered over 12 weekly, 90-minute sessions that combine classroom discussion with graded physical activity in the setting of the football club. Classroom sessions provide participants with a toolbox of behaviour change techniques to initiate and sustain long-term lifestyle changes. The coaches will receive two days of training to enable them to create a positive social environment that supports men in engaging in sustained behaviour change. Discussion: The EuroFIT trial will provide evidence on the effectiveness and cost-effectiveness of the EuroFIT program delivered by football clubs to their male fans, and will offer insight into factors associated with success in making sustained changes to physical activity, sedentary behaviour, and secondary outcomes, such as diet.Trial registration: ISRCTN: 81935608.

Sergey Eisenstein : the use of graphic violence in Strike and Potemkin

textBeing a very prominent film director with several recognisable works, Sergey Eisenstein has been studied extensively from all angles. The aim of this dissertation is to analyse his first two movies, Strike and Battleship Potemkin, both of them stand out when seen in the context of 1920s cinema. Both films are known for introducing strong, graphic violence in cinema and at the same time the films shed light on sensitive social issues such as income disparity, government indifference as well as brutal repressions. Partially due to the fact that these two films come from the nascent Soviet Union and the fear that these films may promote Bolshevik-style revolutions in the West, these two movies were either heavily censored or banned altogether in numerous countries during Eisenstein’s lifetime, which in some ways helped fuel interest in these two movies because censorship or prohibition made watching these two masterpieces more tempting, and therefore in later years they were given the appreciation and respected both films deserved.Russian, East European, and Eurasian Studie
