- Flexible work arrangements permitting workers to work anytime and anywhere are increasingly common. This flexibility can introduce both challenges and opportunities for the organisation, as well as for worker work-life balance (WLB). This cross-sectional study aimed to examine the extent to which occupational factors (organizational, leadership and psychosocial) and individual work-related behaviours (over-commitment, overtime work and boundary management) are associated with WLB, and whether these associations are modified by the perceived level of flexibility at work (i.e., control over when, where, and how to do the work). In total, 2960 full-time office workers with flexible work arrangements at the Swedish Transport Administration participated. Associations were determined using linear regression analyses with adjustment for covariates. The strongest negative associations with WLB were found for over-commitment, quantitative job demands, expectations of availability, and overtime work. Strongest positive associations were found for boundary management, information about organizing work, social support, and relation-oriented leadership. Perceived flexibility was positively associated with WLB, and interacted with several of the examined factors, buffering their negative associations with WLB. Results suggest that WLB can be promoted by organizational initiatives focusing on minimizing excessive job demands, increasing psychosocial resources, supporting boundary management, and enhancing perceived flexibility.

- This study investigated temporal changes in movement strategy and performance during fatiguing short-cycle work. Eighteen participants performed six 7-minutes work blocks with repetitive reaching movements at 0.5 Hz, each followed by a 5.5-minute rest break for a total duration of one hour. Electromyography (EMG) was collected continuously from the upper trapezius muscle, the temporal movement strategy and timing errors were obtained on a cycle-to-cycle basis, and perceived fatigue was rated before and after each work block. Clear signs of fatigue according to subjective ratings and EMG manifestations developed within each work block, as well as during the entire hour. For most participants, timing errors gradually increased, as did the waiting time at the near target. Changes in temporal movement strategy were negatively correlated with changes in the level and variability of EMG, suggesting that an adaptive temporal strategy offset the development of unstable motor solutions in this fatiguing, short-cycle work

Konferensbidrag (refereegranskat)abstract
- Background: Sedentary behavior (SED) has generally increased during the COVID-19 pandemic in people working from home, and physical activity (PA) has therefore decreased. However, it is unclear whether the pandemic has affected office workers in different countries in the same way. We aimed to compare the 24-hour time-use compositions of physical behaviors between Brazilian and Swedish office workers at working and non-working days during the pandemic. Methods: Physical behaviors were monitored over 7 days using thigh-worn accelerometer in 73 Brazilian and 202 Swedish workers. Daily time-use compositions were exhaustively described in terms of SED in short (<30 min) and long (≥30 min) bouts, light PA (LPA), moderate-to-vigorous PA (MVPA), and time-in-bed (TIB). Following a compositional data analysis, isometric log-ratios (ilr) were calculated to express the ratio of TIB to time spent awake, SED (short and long bouts) relative to LPA and MVPA, SED in short relative to long bouts, and LPA relative to MVPA. We examined differences between countries using MANOVA, followed by univariate post-hoc tests of pairwise differences. Results: Both groups spent most of their time SED and in bed. On working days, Brazilian workers spent 294 min in SED in short bouts, 477 min in SED in long bouts, 157 min in LPA, 50 min in MVPA and 461 min TIB; Swedes spent 274, 365, 257, 86 and 458 min, respectively. During non-working days, results were 279, 359, 237, 61 and 504 min among Brazilians and 263, 251, 305, 93 and 529 min among Swedes. Brazilians and Swedes differed significantly in the set of ilrs as a whole during working (p < 0.001) and non-working days (p < 0.001) and in all pairwise comparisons, except for the ratio of TIB to time spent awake during non-working days. Conclusions: During the COVID-19 pandemic Brazilian and Swedish office workers behaved differently. Whether this relates to restrictions being different or to differences even before the pandemic is not clear.

- Background: The COVID-19 pandemic has affected the physical behaviours of office workers worldwide, but studies comparing physical behaviours between countries with similar restrictions policies are rare. This study aimed to document and compare the 24-hour time-use compositions of physical behaviours among Brazilian and Swedish office workers on working and non-working days during the pandemic.Methods: Physical behaviours were monitored over 7 days using thigh-worn accelerometers in 73 Brazilian and 202 Swedish workers. Daily time-use compositions were exhaustively described in terms of sedentary behaviour (SED) in short (<30 min) and long (≥30 min) bouts, light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and time-in-bed. We examined differences between countries using MANOVA on data processed according to compositional data analysis. As Swedish workers had the possibility to do hybrid work, we conducted a set of sensitivity analyses including only data from days when Swedish workers worked from home.Results: During working days, Brazilian office workers spent more time SED in short (294 min) and long (478 min) bouts and less time in LPA (156 min) and MVPA (50 min) than Swedish workers (274, 367, 256 and 85 min, respectively). Time spent in bed was similar in both groups. Similar differences between Brazilians and Swedes were observed on non-working days, while workers were, in general, less sedentary, more active and spent more time-in-bed than during working days. The MANOVA showed that Brazilians and Swedes differed significantly in behaviours during working (p < 0.001, ηp2 = 0.36) and non-working days (p < 0.001, ηp2 = 0.20). Brazilian workers spent significantly more time in SED relative to being active, less time in short relative to long bouts in SED, and more time in LPA relative to MVPA, both during workdays and non-workdays. Sensitivity analyses only on data from days when participants worked from home showed similar results.Conclusions: During the COVID-19 pandemic Brazilian office workers were more sedentary and less active than Swedish workers, both during working and non-working days. Whether this relates to the perception or interpretation of restrictions being different or to differences present even before the pandemic is not clear, and we encourage further research to resolve this important issue.
