Abstract

Background: Sedentary behaviour is grossly prevalent in this day and age because of the advancement in technology. Curbing sedentary behaviour has come to our attention because of the various harmful consequences it can cause like, Obesity, Metabolic syndrome, Insulin resistance, Type-2 diabetes and certain types of cancer. Since desk workers are the most vulnerable population to sedentary behaviour because of the prolonged sitting nature of the occupation, it is essential to find a way to reduce sedentary lifestyle at work. Objective: To explore different types of working conditions and find out how they are related to cognitive performance. Methods: Scopus, Web of Science and PubMed databases were searched for MeSH terms “Energy expenditure”, “cognitive functions”, “memory”, “executive functions”, “workplaces”, “occupations”. The results were summarised as narrative synthesis. Results: Evidence from the 14 trails has demonstrated that standing has a higher energy expenditure (0.5 kcal) than sitting. Considering other interventions with standing, callisthenics has the highest energy expenditure. Existing evidence is inconclusive that active work postures such as standing, treadmill walking/walking and cycling have no impact on cognitive performance. Discussion: Walking or calisthenics results in higher energy expenditure than standing or sitting because of the improved activation of postural muscles and lower limb muscles. Improved or at least maintenance of carotid and vertebral circulation during standing or walking might be the reasons for uninhibited cognitive performance during these postures. Conclusion: Walking or exercise breaks during the typical work day increases significant energy expenditure than standing alone or usual work without affecting cognition.
