“…In congruence with a number of laboratory studies, discomfort increased with time for the low back [12], lower limb [18] and also the upper limb [51]. Clinically meaningful increases were evident for low back (10 participants) and hip/thigh/buttock (nine participants) discomfort.…”

Office workers are exposed to high levels of sedentary time. In addition to cardio-vascular and metabolic health risks, this sedentary time may have musculoskeletal and/or cognitive impacts on office workers. Participants (n = 20) undertook two hours of laboratory-based sitting computer work to investigate changes in discomfort and cognitive function (sustained attention and problem solving), along with muscle fatigue, movement and mental state. Over time, discomfort increased in all body areas (total body IRR [95% confidence interval]: 1.43 [1.33–1.53]) reaching clinically meaningful levels in the low back and hip/thigh/buttock areas. Creative problem solving errors increased (β = 0.25 [0.03–1.47]) while sustained attention did not change. There was no change in erector spinae, trapezius, rectus femoris, biceps femoris and external oblique median frequency or amplitude; low back angle changed towards less lordosis, pelvis movement increased, and mental state deteriorated. There were no substantial correlations between discomfort and cognitive function. The observed changes suggest prolonged sitting may have consequences for musculoskeletal discomfort and cognitive function and breaks to interrupt prolonged sitting are recommended.

Background Breaking up sedentary behavior with standing or walking can decrease discomfort, fatigue, and sleepiness. However, less is known about acceptability and impact of resistance exercise breaks on these outcomes. Therefore, we evaluated the acceptability of resistance exercise breaks and their influence on discomfort, physical and mental fatigue, and sleepiness during occupational sitting. Methods Workers completed two 4-hour conditions in random order: prolonged sitting (SIT) and sitting with hourly resistance exercise breaks (REX). All outcomes were measured at baseline and every hour thereafter with five total breaks. Linear mixed models evaluated overall condition effects and differences at each hour. Cohen’s d estimated magnitudes of effect. Acceptability was assessed via questionnaire after the REX condition and reported as percentages. Findings Fourteen adults (age: 53.4 ± 9.5 years, body mass index [BMI]: 30.9 ± 4.8 kg/m2) were enrolled. Although ratings of discomfort, fatigue, and sleepiness were typically lower during REX as compared with SIT, overall outcomes were not significantly different between conditions ( p > .05). However, a significant reduction in mental fatigue at hour 4 in favor of the REX condition (β = −0.48 log-points, p < .05, d = 0.37) was observed. Program acceptability questions revealed the majority (>50%) of participants reported a “4” or “5” on a 5-point Likert-type scale for all questions, indicating high acceptability for implementation. Conclusions/Application to Practice Resistance exercise breaks had high acceptability and provided preliminary evidence of improving ratings of mental fatigue. More research is needed to better understand the role of resistance training to reduce sedentary behavior.

“…Teaching is also done in static posture (sitting or standing) with the remaining period in the lecturer's office. A 2016 conference on human factor and ergonomics affirmed that a long stretch in a particular posture such as prolonged mouse and keyboard use, long hours at meetings and other academic activities together with high workload and stress are contributory risk factors for the development of work-related musculoskeletal disorders [19].…”

Background: Improper work postures have been associated with many detrimental health outcomes including musculoskeletal disorders. Emerging evidence however suggests that some of these health concerns may be lessened by reducing sedentary behaviour at work. Musculoskeletal disorders have been ranked top among the most prevalent health problems relating directly to working conditions. Aim: This study was thus aimed at determining the prevalence of musculoskeletal disorder symptoms and their relationship with work posture among staff of the University of Port Harcourt in Rivers State, Nigeria. Materials and Methods: A descriptive, cross sectional design was used in conducting this study among academic and non-academic staff of the University of Port Harcourt. 256 study participants were involved in this study. They were selected using the multistage sampling technique. A self-administered semi-structured questionnaire was the study instrument. Collected data was transferred to the Microsoft Excel (2016) software for cleaning and coding. The Statistical Package for Social Science was used for analysis of the data. Descriptive and inferential statistics were computed and statistical significance was set at <0.05. Results: Majority 172 (54.3%) of the respondents had experienced musculoskeletal pain that involved the head, neck, back and other regions of their bodies. Also, a statistically significant association was found to exist between work posture and the occurrence of pelvic and perineal pain. Dynamic postures while working was found to offer a protective effect against the occurrence of thoracic and abdominal pain (O.R. = 0.88). Conclusion and Recommendations: Work-related musculoskeletal disorder symptoms were found to be prevalent in this study. The relationship between work postures and the identified symptoms among the staff was also established. It was recommended that health information on alternation between sitting and standing working postures be passed on to staff working in the study area as well as a redesigning of the work-stations of the staff to adopt ergonomic standards necessary for preventing the occurrence of work-related musculoskeletal disorders.
