Pedometry bývají často využívány v preskribci pohybové aktivity. Přes velké množství validačních studií není dostatečně objasněna jejich funkce v podmínkách běžného života. Cílem naší práce bylo zhodnotit funkci dvou často užívaných pedometrů (pružinový Yamax SW-200, elektronický Omron HJ 720-IT) při jízdě autobusem. Z našich dat vyplývá, že pro menší zkreslení při monitorování pohybové aktivity pedometrem je vhodnější dražší elektronický pedometr.

Pedometers are often used during physical activity prescription. Even there are many validation studies, function of pedometers in free-living conditions is not sufficiently elucidated. In our work we aimed to assess function of two widely used pedometers (spring-levered Yamax SW-200, electronical Omron HJ 720-IT) during bus travel. Our results indicate that lesser error in physical ativity monitoring can be achieved by using of more expensive electronic pedometer.

Objective measured trend data are important for public health practice. However, these data are rare for an adult population. Therefore, the aim of this study was to describe time trends in pedometer-determined physical activity of Czech adults (25-65 years) from 2008 to 2013. Participants were Czech national citizens whose physical activity was assessed objectively using a Yamax Digiwalker SW-700 pedometer (Yamax Corporation, Tokyo, Japan) for seven consecutive days in the period 2008 to 2013. The final sample was 4647 Czech adults [M age 41.4 ± 10 years; M body mass index (BMI) 25.1 ± 3.7 kg/m²]. The results showed that men took more steps/day (M (Mean) = 10,014; 95% CI (Confidence Interval) = 9864-10,164) than women (M = 9448; 95% CI = 9322-9673) in all age and BMI groups. Mean steps/day declined from 2008 to 2013 by 852 steps/day in men and 1491 steps/day in women. In the whole sample, the proportion of participants who had a sedentary lifestyle (<5000 steps/day) increased by 5.8%; the proportion taking ≥10,000 steps/day decreased by 15.8%. In 2013, men and women were 2.67 and 2.05 times, respectively, more likely to have a physically inactive lifestyle (<7500 steps/day) than in 2008. Conversely, in 2008, men and women were 1.68 and 2.46 times, respectively, less likely to have very active lifestyle (>12,500 steps/day). In conclusion, this study suggests that there has been a substantial reduction in physical activity in Czech adults over time.

This study focuses on determining the relationship between parents' step count (SC) and screen time (ST) and children's SC and ST on weekdays and at weekends. The participants (278 parents aged 30-45 and their 194 children aged 4-7) were recruited from 10 randomly selected Czech kindergartens. The participants recorded SC and ST duration over a week-long monitoring (≥8 h/day) during September-October 2014 and April-May 2015. The associations between parents' SC and ST and children's SC and ST were estimated using general linear regression for weekdays and weekends. Each 2500 SC increase in mothers'/fathers' daily SC at weekdays (weekends) was associated with an extra 1143/903 (928/753) daily SC in children. Each 60 min of ST increase in mothers'/fathers' ST at weekdays (weekends) was associated with an extra 7.6/7.6 (16.8/13.0) min of child daily ST. An increase of 2500 mothers' daily SC was associated with reduction of 2.5 (7.5) min of ST in children at weekdays (weekends). This study reveals a significant relationship between parent-child SC/day, parent-child ST/day, and mothers' ST and children's SC at weekends. Weekend days seem to provide a suitable space for the promotion of joint physical activity in parents and their pre-schoolers.

BACKGROUND: General practitioners play a fundamental role in combatting the current epidemic of physical inactivity, and pedometer-based walking interventions are able to increase physical activity levels of their patients. Supplementing these interventions with email counseling driven by feedback from the pedometer has the potential to further improve their effectiveness but it has to be yet confirmed in clinical trials. Therefore, the aim of our pilot randomized controlled trial is to evaluate the feasibility and potential efficacy of future trials designed to assess the additional benefit of email counseling added to a pedometer-based intervention in a primary care setting. METHODS: Physically inactive patients were opportunistically recruited from four general practices and randomized to a 12-week pedometer-based intervention with or without email counseling. To explore the feasibility of future trials, we assessed the speed and efficiency of recruitment, adherence to wearing the pedometer, and engagement with email counseling. To evaluate the potential efficacy, daily step-count was the primary outcome and blood pressure, waist and hip circumference, and body mass were the secondary outcomes. Additionally, we conducted a qualitative analysis of structured interviews with the participating general practitioners. RESULTS: The opportunistic recruitment has been shown to be feasible and acceptable, but relatively slow and inefficient; moreover, general practitioners selectively recruited overweight and obese patients. Patients manifested high adherence, wearing the pedometer on 83% (± 20) of days. All patients from the counseling group actively participated in email communication and responded to 46% (± 22) of the emails they received. Both groups significantly increased their daily step-count (pedometer-plus-email, + 2119, p = 0.002; pedometer-alone, + 1336, p = 0.03), but the difference between groups was not significant (p = 0.18). When analyzing both groups combined, there was a significant decrease in body mass (- 0.68 kg, p = 0.04), waist circumference (- 1.73 cm, p = 0.03), and systolic blood pressure (- 3.48 mmHg, p = 0.045). CONCLUSIONS: This study demonstrates that adding email counseling to a pedometer-based intervention in a primary care setting is feasible and might have the potential to increase the efficacy of such an intervention in increasing physical activity levels. TRIAL REGISTRATION: The trial was retrospectively registered at ClinicalTrials.gov (ID: NCT03135561 , date: April 26, 2017).

This study investigates whether more physically active parents bring up more physically active children and whether parents' level of physical activity helps children achieve step count recommendations on weekdays and weekends. The participants (388 parents aged 35-45 and their 485 children aged 9-12) were randomly recruited from 21 Czech government-funded primary schools. The participants recorded pedometer step counts for seven days (≥10 h a day) during April-May and September-October of 2013. Logistic regression (Enter method) was used to examine the achievement of the international recommendations of 11,000 steps/day for girls and 13,000 steps/day for boys. The children of fathers and mothers who met the weekend recommendation of 10,000 steps were 5.48 (95% confidence interval: 1.65; 18.19; p < 0.01) and 3.60 times, respectively (95% confidence interval: 1.21; 10.74; p < 0.05) more likely to achieve the international weekend recommendation than the children of less active parents. The children of mothers who reached the weekday pedometer-based step count recommendation were 4.94 times (95% confidence interval: 1.45; 16.82; p < 0.05) more likely to fulfil the step count recommendation on weekdays than the children of less active mothers.

BACKGROUND: To explore the time trends (2005-2015) of pedometer-determined weekday and weekend physical activity (PA) and obesity prevalence in 4-7-year-old Czech preschool children and changes in proportion of kindergarten vs. leisure-time PA. METHODS: The study compared data of two cross-sectional cohorts of preschool children (2005: 92 boys and 84 girls; 2015: 105 boys and 87 girls) in the Czech Republic, using the same measurements and procedures in both cases. PA was monitored by the Yamax Digiwalker SW-200 pedometer for at least eight continuous hours a day over seven consecutive days. Body weight and height were measured using calibrated Tanita scales and anthropometry. The analysis of variance was conducted to examine the gender and cohort effect on step counts. The t-test was used to examine the difference in step counts in kindergarten (or leisure-time) between non-obese and obese children, and the chi-square test compared the prevalence of obesity between 2005 and 2015. RESULTS: The steps/day (mean ± standard deviation) of preschoolers was significantly higher (p < 0.05) in 2015 (11,739 ± 4,229 steps/day) than in 2005 (10,922 ± 3,181 steps/day); and (p < 0.001) in boys (11,939 ± 3,855 steps/day) than in girls (10,668 ± 3,587 steps/day). In 2015, girls, but not boys, had a significantly (p < 0.01) greater step count on weekdays than in 2005, but not at weekends. A decline of leisure-time step counts on weekdays between 2005 and 2015 in girls (6,8652005 vs. 6,0592015, p < 0.01) and boys (7,8612005 vs. 6,4362015, p < 0.001) is compensated for by the increase of step counts in kindergarten (girls: 3,0582005 vs. 5,3302015, and boys: 4,0032005 vs. 5,9992015, p < 0.001). The prevalence of obesity was not significantly different either in 2005 or 2015 among preschool girls (7.14 % 2005 vs. 9.20 % 2015) or boys (6.52 % 2005 vs. 9.52 % 2015). CONCLUSION: The steps/day of preschoolers was higher in 2015 than in 2005; this higher level of PA was the result of increased PA in kindergartens over the last ten years, particularly among girls. Thus, the current PA program in kindergartens effectively compensates for the decline in PA in leisure-time of weekdays of non-obese and obese preschoolers compared to 2005 and 2015. Prevalence of obesity among Czech preschool children remains relatively stable between 2005 and 2015.

Chronické srdeční selhání (CHSS) je spojeno s vysokou mortalitou i morbiditou, významně ovlivňuje kvalitu života pacientů a péče o pacienty s CHSS je nákladná. Pravidelné cvičení je všeobecně spojováno se zlepšením zdravotního stavu u širokého spektra chronicky nemocných. Přiměřeně navržený cvičební program může být hodnotnou součástí komplexní péče o dospělé pacienty s CHSS a v tomto smyslu je pravidelná chůze považována za vhodný typ fyzické aktivity. Krokoměry jsou levné, jednoduché přístroje, které poskytují informaci o úrovni fyzické aktivity, která je snadno srozumitelná a hodnotitelná. Navíc je používání krokoměrů spojeno s významným zvýšením fyzické aktivity u řady různých skupin nemocných. Projekt je navržen jako multicentrická, randomizovaná studie, která by měla zhodnotit, zda šestiměsíční chodecká intervence s využitím krokoměru v kombinaci s osobními návštěvami a telefonickými kontakty ve srovnání s běžnou péčí zlepšuje fyzickou zdatnost (hodnocenou šestiminutovým testem chůze) a neurohumorální modulaci u pacientů s CHSS.; Chronic heart failure (CHF) is associated with high mortality and morbidity, significantly affects patient ́s quality of life and is resource demanding. Regular exercise training is generally associated with improved health outcomes in a wide spectrum of chronically ill individuals. Adequately designed exercise rehabilitation may be an effective part of complex care for adults with CHF. Regular walking is considered to be a suitable mode of physical activity for patients with CHF. Pedometers are low-cost, simple devices that provide information regarding physical activity level that is easy to understand and evaluate. Moreover, pedometer use is associated with significant increases in physical activity in different populations. The project is designed as a multicenter randomized trial to determine whether a 6-month pedometer-based intervention combinig regular face-to-face appointments and telephone contacts improves functional tolerance, as measured by 6-minute walk test (6MWT) and neurohumoral regulation in patients with chronic heart failure compared to usual care.

Využívání pedometrů je historicky nejstarší m a v současnosti nejrozšířenějším způsobem validního a zároveň jednoduchého přístrojového sledování terénní pohybové aktivity. Pedometr je komerčně dostupný, malý a lehký elektronický přístroj měřící vertikální oscilace, jejichž souhrnný počet je zobrazován na displeji přístroje. Pedometry jsou nejpřesnější při monitorování chůze a celodenní pohybové aktivity. Pro věrné zachycení běžné celodenní pohybové aktivity je doporučováno 6denní a delší monitorování při umístění pedometru v pase na boku jedince. Pohybová aktivita ekvivalentní 15 000 (resp. 12 000) krokům denně s vysokou pravděpodobností zabrání vzniku obezity u 6–12letých chlapců (resp. dívek). Pro podporu zdraví pohybovou aktivitou je u 6-12letých chlapců (resp. dívek) doporučováno denně vykonat alespoň 13 000 (resp. 11 000) kroků.

Pedometers are historically the oldest and at present the most widespread valid device to monitor field physical activity. Pedometer is a commercially available, small and light electronic motion sensor that records the acceleration and deceleration of movement in one direction. The display shows the total number of movement oscillations. Pedometers are the most accurate for the quantification of walking and assessment of total daily activity. To record reliably habitual daily physical activity, 6-day and longer monitoring with pedometer placed at the waist of an individual is recommended. Physical activity equivalent of 15,000 (or 12,000) steps per day with high probability prevents the occurence of obesity in 6–12-year old boys (or girls). Guidelines for the amount of physical activity necessary for health promotion contains at least 13,000 (or 11,000) steps per day in 6–12-year old boys (or girls).

The main aim of this study is to examine familial aggregation in pedometer-assessed physical activity (PA) and proxy-reported screen time (ST) with estimating which of the parents' lifestyle indicators help their offspring achieve step count (SC) recommendations under daily life conditions. The analysis included 773 parent-child dyads (591 mother-child, 182 father-child) and 511 nuclear family triads (mother-father-child) with data ambulatory PA monitored with a Yamax pedometer during a regular school/working week during the spring and autumn between 2013 and 2019. Based on Logistic regression analysis, an achievement of 10,000 steps a day by the mothers significantly (p < 0.001) increases the odds ratio of their children reaching the recommended daily SC in the parent-child dyads. Obesity/overweight of mothers (fathers) significantly (p < 0.05) increases (reduces) the chance of their children reaching the recommended daily SC in the analysis of the nuclear family triads. For both overweight/obese and non-overweight children, the odds of reaching the recommended daily SC are significantly (p < 0.05) increased by their regular participation (≥ twice per week) in organised leisure-time PA (analysis of the nuclear family triads) and non-excessive entertainment ST (≤2 h per day) in the mother-child and nuclear family triads. Despite the different mother-/father-child behavioural associations, SC of parents are positively associated with SC of their children (Linear regression analysis). The involvement of children in regular participation in organised leisure activities (at least twice a week) and limiting their excessive entertainment ST might be important factors contributing to the achievement of the recommended daily SC by children.

BACKGROUND: Regular physical activity is recommended for patients with chronic heart failure to improve their functional capacity, and walking is a popular, effective, and safe form of physical activity. Pedometers have shown potential to increase the amount of walking across a range of chronic diseases, but it is unknown whether a pedometer-based intervention improves functional capacity and neurohumoral modulation in heart failure patients. METHODS: Two multicenter randomized controlled trials will be conducted in parallel: one in patients with chronic heart failure with reduced ejection fraction (HFrEF), the other in patients with chronic heart failure with preserved ejection fraction (HFpEF). Each trial will consist of a 6-month intervention with an assessment at baseline, at 3 months, at the end of the intervention, and 6 months after completing the intervention. Each trial will aim to include a total of 200 physically inactive participants with chronic heart failure who will be randomly assigned to intervention or control arms. The 6-month intervention will consist of an individualized pedometer-based walking program with weekly step goals, behavioral face-to-face sessions with a physician, and regular telephone calls with a research nurse. The intervention will be based on effective behavioral principles (goal setting, self-monitoring, personalized feedback). The primary outcome is the change in 6-min walk distance at the end of the 6-month intervention. Secondary outcomes include changes in serum biomarkers levels, pulmonary congestion assessed by ultrasound, average daily step count measured by accelerometry, anthropometric measures, symptoms of depression, health-related quality of life, self-efficacy, and MAGGIC risk score. DISCUSSION: To our knowledge, these are the first studies to evaluate a pedometer-based walking intervention in patients with chronic heart failure with either reduced or preserved ejection fraction. The studies will contribute to a better understanding of physical activity promotion in heart failure patients to inform future physical activity recommendations and heart failure guidelines. Trial registration The trials are registered in ClinicalTrials.gov, identifiers: NCT03041610, registered 29 January 2017 (HFrEF), NCT03041376, registered 1 February 2017 (HFpEF).
