“…While the term executive function is broad, it generally refers to the hypothesized processes that control other brain processes that are critical to everyday functioning (Hughes, 2013). The limited available literature does indicate that prolonged sitting decreases cerebral blood flow by 5% (Carter et al, 2018), cerebral vascular conductance by 6% (Carter et al, 2018), increases perceived fatigue by 25% (Wennberg et al, 2016), and increases problem solving errors by 56% (Baker, Coenen, Howie, Williamson, & Straker, 2018). Conversely, regular walking breaks prevent the decline in cerebral blood flow associated with prolonged sitting (Carter et al, 2018).…”

Exposure to acute prolonged sitting reportedly leads to decreased cerebral blood flow. However, it is unclear whether this exposure translates to decreased cerebral perfusion and executive function or whether simple strategies to break up sitting can maintain cerebral perfusion and executive function. This study sought to answer two questions: in young, healthy adults, (a) does prolonged (3 hr) sitting lead to decreased cerebral perfusion and executive function? and (b) does breaking up prolonged sitting, using intermittent calf raise exercises, prevent changes in cerebral perfusion and executive function? Twenty young, healthy participants (21.7 [2.5] years, 70% female, 25.5 [6.1] kg/m2) were randomized to 3 hr sitting with 10 calf raises every 10 min (CALF) and 3 hr sitting without intermittent calf raises (CON). Prefrontal cortex perfusion was assessed using near‐infrared spectroscopy to monitor total hemoglobin (tHB) concentration and tissue saturation index (TSI, oxygenated hemoglobin). Executive function was assessed using the Stroop word and color tasks. Following 3 hr sitting, tHb was significantly lower in CALF versus CON (−2.1 μM, 95% CI [−3.1, −1.1]). TSI was not significantly different between conditions (p = .667). Word (1.6 ms, 95% CI [0.7, 2.5]) and color (1.3 ms, 95% CI [−0.2, 2.8]) completion times were longer (worse) for CALF compared to CON. In conclusion, calf raises decreased both cerebral perfusion and executive function. Simple strategies, such as fidgeting or calf raises, which have been reported to preserve vascular function in the legs, appear not to be sufficient to benefit cerebral perfusion or executive function.

“…The longer sitting hours (6-10 hours) was reported by most of the faculty. Sitting for longer hours is detrimental to health and increases the cardiovascular and metabolic risk along with risk to musculoskeletal health.as reported by Baker, Williamson, & Straker (2018) in their study. Lack of physical exercises and sitting for longer hours may increase the problem of overweight and obesity among the faculty.…”

Background and aim: Health promotion is one of the vital and key element for a healthy living. The health care professional spent their initial developing years in learning about health and thereafter training and imparting knowledge to their students and people to whom they serve. The faculty of health sciences are the educators who not only teach health promotion to their students but also educate and prepare the students for the health promotion of the society. Aim: The purpose of the study was to assess the perception of health promotion and health promotion practices existing among the faculty of Medical and Health Sciences University, Ras Al Khaimah, UAE.Study design: The study was descriptive and cross sectional. Data was collected using convenience sampling technique. Self-administered questionnaire was used for data collection. The sample size of the study was 52.Results: Of the total 52 respondents, majority were females, 31-50 years old (63%), married (87%) from nursing and medical faculty ( 63%), non arabic (77%), with 20 or less years of total professional experience(62%). About 52% of the faculty reported that their daily routine comprises sitting at one place for 6-10 hours. Majority (98%) of the participant felt that health promotion is most important for healthy living and is the best resource for everyday life (100%). However majority (60%) of the faculty reported that they do not find time to perform health promotion activities especially daily physical exercises and only 39% were actually able to perform their daily exercises.CONCLUSION: Though health promotion activities are most important for healthy living, the physical exercises as essential health promotion activities are not practiced by the health sciences university faculty.

“…Durations of sitting ranged from 1 hour to an average of 6.96 h/d (including breaks) for 5 days with the sitting duration in most studies (8 of 10) being between 1 and 3 hours. In all studies, ratings of perceived LBP or discomfort were made with a C10 Borg Scale, 43 a visual analog scale (10 cm 21,36,40 or 100 mm 38,39,42 ), the Nordic Musculoskeletal Questionnaire, 37,41 or the 5-point numerical rating scale. 35 Attempts were made to contact authors directly where pain rating data were presented with no reference to baseline measures.…”

Objective: The purpose of this study was to conduct a systematic review of studies to determine whether sitting time measured objectively (by laboratory controlled time trial, direct observation, or wearable sensor) is associated with the immediate increase in low back pain (LBP) (determined by pain scale rating) in people >18 years of age. Methods: Four databases (PubMed, EMBASE, SPORTDiscus, and Cumulative Index to Nursing and Allied Health Literature) were searched from inception to September 1, 2018. Randomized controlled trials and cohort and crosssectional studies, where objectively measured sitting time was temporally matched with a measure of LBP in adults, were included. Studies without a control session conducted on a separate day were excluded. Screening, full-text review, data extraction, and risk of bias assessment (Quality In Prognosis Studies) of included papers were performed independently by 2 reviewers, with a third available to resolve disagreements. Results: In total, 609 articles were identified, 361 titles/abstracts were screened,75 full-text articles were assessed for eligibility, and 10 met the inclusion criteria. All but 1 reported sitting time to be associated with an immediate increase in LBP. Six of these reported clinically relevant pain levels (n ¼ 330). Half of the included studies were rated as having a low risk of bias and the remaining were rated as having a moderate risk of bias. Conclusion: Prolonged sitting increases immediate reporting of LBP in adults; however, no conclusion between sitting and clinical episodes of LBP can be made. Based upon these findings, we recommend that future prospective studies should match objectively measured sitting with temporally related pain measurements to determine whether prolonged sitting can trigger a clinical episode of LBP. (J Manipulative Physiol Ther 2020;43:1-12) No language restrictions were used, and all articles that met the inclusion criteria for study design and population, exposure, and LBP were included for analysis.Study Design and Population.
