This study examines the stressor-response process in physical activity among 226 participants across four countries. We analyzed their step count collected via activity monitors before and after a significant stressor: the COVID-19 lockdown. Results showed that a 'local dynamic complexity' metric significantly predicts the rate of recovery to pre-COVID levels of physical activity. These findings provide new opportunities for just-in-time interventions to support physical activity recovery after disruptive stressors.

INTRODUCTION AND OBJECTIVE: Weekly physical activity (PA) in adolescents is significantly correlated with the educational programme and school environment, where the basis of healthy work habits and a healthy lifestyle is laid. The aim of the study was to identify the differences in the trend and the structure of the weekly step count in adolescent boys and girls in the context of the Polish school environment. MATERIAL AND METHODS: A total of 930 boys and 1,354 girls aged 15-19 years from 64 secondary schools in the Katowice region participated. The research was conducted between 2011-2018. For the objective monitoring of weekly PA, Yamax Digiwalker SW-700 pedometers were used. RESULTS: Between 2011-2014 and 2015-2018, no significant differences were observed in step counts on an average week day, school day, or weekend day. This means that the level of PA, expressed as daily step count, did not decrease between the two 4-year periods. On average, boys performed 10,799 steps/day, while girls performed 10,130 steps/day. The recommendation of 11,000 steps/day was achieved by 42.2% of boys and 35.3% of girls. A significant decrease by 8.6 percentage points in the achievement of 11,000 steps/day between the two 4-year periods was observed only in boys. CONCLUSIONS: It is positive that in the 8-year monitoring of PA, there was no significant decrease in the average steps/day for Polish boys and girls. However, most boys and girls did not meet the 11,000 steps/day recommendation. Both boys and girls were most physically active on Friday and least physically active on Sunday.

Background: Walking represents a major component of physical activity (PA), and its restriction could degrade autonomy and quality of life. An important objective for preventive and/or rehabilitative strategies to improve balance and gait in normal and pathological aging conditions is to focus on physical activity. Activity monitors have recently been getting increasingly popular and represent a modern solution to measure-and communicate-PA notably in terms of steps/day. These activity monitors are well-suited for various populations as they can be worn on a variety of locations on the body, including the wrist and the hip (i.e., the two most common locations), in an undifferentiated way according to the manufacturer's instruction. The aim of this study was hence to verify potential differences in step count (SC) by comparing this parameter assessed using wrist- and hip-worn activity trackers over a 24-h period in free-living conditions in young and older adults. Methods: Young adults (n = 22) and older adults (n = 22) voluntarily participated in this study. They were required to wear two commercially-available Actigraph GT3X+ activity monitors simultaneously at two locations recommended by the manufacturer, i.e., one positioned around the wrist and one above the hip, over a 24-h period in free-living conditions. The manufacturer's software was used to obtain estimates of the SC. Results: For both groups, the wrist-worn activity tracker provided significantly higher SC than the hip-worn activity tracker did. For both placements on the body, older adults exhibited significantly lower SC than young adults. Interestingly, for both young and older participants, the difference between both measurements tended to decrease for longer distances. Conclusion: The different estimations of the step count provided by the comparison between two identical Actigraph GT3x on the wrist or the hip during the 24-h observation period in free-living conditions in young and older adults strongly suggests that caution is needed when using total step per day values as an outcome to quantify walking behavior. Probably we can suggest the same caution across implementation of different activity Tracker.

Eozinofily byly jako unikátní skupina bílých krvinek poprvé pojmenovány na konci 19. století Paulem Ehrlichem podle afinity jejich specifických granulí ke kyselému syntetickému barvivu eozinu. Od doby svého objevu byl jejich výskyt v organismu spojován s bronchiálním astmatem a helmintózami. V dnešní době již víme, že jejich deregulovaná aktivita, spojená se zvýšením jejich počtu v periferní krvi nad normální hodnotu, je spojena s celou řadou dalších onemocnění, která se souhrnně označují jako eozinofilní syndromy. Eozinofilní typ astmatu je jedním z nich. Předpokládá se, že asi polovina eozinofilních syndromů postihuje respirační trakt a obráceně, asi polovina bronchiálních astmat vykazuje známky ryze eozinofilního zánětu dle počtu eozinofilů v indukovaném sputu. Vyšetření eozinofilů v periferní krvi by tak mělo být nedílnou součástí základního vyšetření pacientů v rámci široké diferenciální diagnostiky plicních nemocí, včetně astmatu. Mělo by být prováděno opakovaně, vždy v době diagnózy a ideálně před nasazením jakékoli protizánětlivé terapie a dále při exacerbacích základní choroby. Pokud již byly nasazeny pulzní systémové kortikosteroidy, mělo by být následné vyšetření eozinofilů provedeno s dostatečným časovým odstupem po jejich vysazení. Informace o eozinofilii periferní krve by měla být vždy impulzem k pečlivému vyšetření nemocného s cílem prokázat či vyloučit její primární, resp. sekundární příčinu a dále případné orgánové postižení s eozinofilií spojené. V případě bronchiálního astmatu je průkaz zvýšení počtu eozinofilů klíčový nejen pro klasifikaci zánětlivého fenotypu astmatu, ale i pro další možné léčebné kroky, mezi něž se u těžkých astmat řadí i biologická léčba.
Eosinophils, a distinct group of white blood cells, were named by Paul Ehrlich in the late 19th century based on the affinity of their specific granules for the synthetic acidic dye eosin. Since their discovery, their occurrence in the body has been associated with bronchial asthma and helminthiasis. Today, we already know that their deregulated activity, associated with their peripheral blood count blood above the normal limit, is linked to a number of other diseases, collectively referred to as eosinophilic syndromes, one of them being eosinophilic bronchial asthma. It is estimated that in about half of eosinophilic syndrome cases, the respiratory tract is involved and, conversely, in about half of bronchial asthma cases, eosinophilic inflammation is revealed based on the number of eosinophils in induced sputum. Therefore, the peripheral blood eosinophil count should be an integral part of the basic examination of patients and broad differential diagnosis of lung diseases, including asthma. It should be performed repeatedly, always at the time of diagnosis and, ideally, before the initiation of any anti-inflammatory therapy, as well as during exacerbations of the underlying disease. If pulse systemic corticosteroids have already been administered, the eosinophil count should be performed sufficiently long after their discontinuation. Infor- mation about peripheral blood eosinophilia should always be an impetus for a careful examination of the patient in order to confirm or rule out its primary or secondary causes as well as possible organ involvement associated with eosinophilia. In bronchial asthma, confirming the high eosinophil count is crucial not only for classification of the inflammatory phenotype of asthma, but also for other possible therapeutic steps, including biological treatment for severe asthma.
The pedometer is a widely used research tool for measuring the level and extent of physical activity (PA) within population subgroups. The sample used in this study was drawn from a population of university students to examine the influence of the monitoring interval and alternate starting days on step-count activity patterns. The study was part of a national project during 2008-2010. Eligible subjects (641) were selected from a sample of 906 university students. The students wore pedometers continuously for 7 days excluding time for sleep and personal hygiene. Steps per day were logged on record sheets by each student. Data gathering spanned an entire week, and the results were sorted by alternate starting days, by activity for an entire week, by activity for only the weekdays of the one-week monitoring interval and for the two-day weekend. The statistical analysis included ANOVA, intra-class correlation (ICC) analysis, and regression analysis. The ICC analysis suggested that monitoring starting on Monday (ICC = 0.71; 95%CI (0.61-0.79)), Tuesday (ICC = 0.67; 95%CI (0.59-0.75)) or Thursday (ICC = 0.68; 95%CI (0.55-0.79)) improved reliability. The results of regression analysis also indicated that any starting day except Sunday is satisfactory as long as a minimum of four days of monitoring are used.

Cieľom bolo zmapovať pomocou krokomerov pohybovú aktivitu zamestnancov so sedavým spôsobom práce a s telesnou aktivitou v zamestnaní. Počet krokov vo voľnom čase a v zamestnaní korelovať s údajmi o životospráve a pohybových návykoch. Metodika: Sledovaných bolo 186 probandov, sedavé zamestnanie malo 118 osôb (skupina A), zamestnanie s telesnou aktivitou 68 osôb (skupina B). Počet krokov zistený počas 4hodinového merania vo voľnom čase a v zamestnaní bol korelovaný s výsledkami niektorých antropometrických meraní a s odpoveïami v dotazníku zameranom na určenie povahy pohybovej činnosti v zamestnaní a vo voľnom čase. Výsledky: Vo vekovo porovnateľných súboroch sme zistili významný rozdiel (p < 0,003) v počte krokov vykonaných v zamestnaní medzi skupinou so sedavým zamestnaním (2 892 krokov) a zamestnaním s telesnou aktivitou (3 595 krokov). Rozdiel v počte krokov vo voľnom čase (A: 3 089, B: 2 402) nebol štatisticky významný (p = 0,151). V skupine B bol významný rozdiel (p < 0,0001) v počte krokov v zamestnaní (3 595) a vo voľnom čase (2 402), v skupineA bol rozdiel (v zamestnaní 2 892 krokov, vo voľnom čase 3 089 krokov) štatisticky menej významný (p < 0,003). V oboch skupinách (A aj B) bola priama súvislosť (p < 0,01) medzi BMI a % podielom tuku v tele v celom súbore, ako aj samostatne pre mužov a ženy. Pri rozdelení súboru podľa pohlavia bolo možné pozorovať u mužov aj u žien proporcionálny pokles počtu krokov (vo voľnom čase aj v zamestnaní) so stúpajúcim vekom. So stúpajúcim BMI klesal v oboch skupinách počet krokov vo voľnom čase aj v zamestnaní. Žiadna zo sledovaných skupín a podskupín nedosahovala literatúrou odporúčané počty krokov na deň.
The objective of this research was to measure the physical activity of employees with sedentary type of occupation (group A, 186 subjects) and employees with physical activity during work (group B, 68 subjects) by means of pedometers. Gained pedometric data were correlated with some anthropometric and enquiry data. A significant difference (p < 0,003) in the step counts during working time between the A group (2 892 steps) and B group (3 595 steps) was detected. The difference in step counts during leisure time (A: 3 089, B: 2 402) was insignificant (p = 0,151). In the group B, there was a highly significant difference (p < 0,0001) between the step count in working time (3 595) and in leisure time (2 402), whereas equal difference in the group A (2 892 / 3 089 steps) was less significant (p < 0,003). Both groups displayed direct association (p < 0,01) between BMI and the percentage body fat not only in the entire subject pool but also separately for men and women. If splitting the subjects according to their gender, both in men and in women a proportional decline of their step counts (in leisure time and in working time) was observed with increasing age. The step count in leisure time and in working time declined with increasing BMI in both genders.
