Sedentary time has been found to be independently associated with poor health and mortality. Further, a greater proportion of the workforce is now employed in low activity occupations such as office work. To date, there no research that specifically examines contribution sedentary work overall exposure thus risk. The purpose study was determine total pattern for time, light moderate/vigorous physical (MVPA) workers during non-work time. 50 from Perth, Australia wore an Actical (Phillips,...

In Brief Study Design. A comparative study. Objectives. To investigate sitting postures of asymptomatic individuals and nonspecific chronic low back pain (NS-CLBP) patients (pooled subclassified) evaluate the importance subclassification. Summary Background. Currently, little evidence exists to support hypothesis that CLBP sit differently from pain-free controls. Although classifying NS-CLBP into homogeneous subgroups has been previously emphasized, no attempts have made consider such...

A cross-sectional comparative study between healthy controls and two subgroups of nonspecific chronic low back pain (LBP) patients.To determine differences in trunk muscle activation during usual unsupported sitting.Patients with LBP commonly report exacerbation on sitting. Little evidence exists to confirm that patients use different motor patterns sitting than pain-free controls.A total 34 33 subjects were recruited. Two blinded clinicians classified into (active extension pattern flexion...

Physical activity, physical fitness and motor competence are important health‐related constructs. However, the relationship among them, particularly for children adolescents, is still unclear. In this study, (measured by McCarron Assessment of Neuromuscular Development), pedometer‐determined activity (aerobic fitness, muscle strength, endurance, flexibility body composition) were examined in a cohort 1585 adolescents (771 girls, 814 boys) mean age 14.06 years. Significant gender differences...

Shifting workforce proportions to sedentary occupations and technology developments in traditionally physically demanding have resulted low physical workloads for many workers. Insufficient stress is known detrimental short- long-term effects on health capacity. It argued herein that modern workers are at risk of insufficient workload. Further, it the traditional ergonomics paradigm reducing by loads ('less better') not appropriate occupations. proposed a new required, where 'more can be...

A prospective study of the sagittal standing posture 766 adolescents.To determine whether subgroups based on photographic assessment are similar to those used clinically and previous, radiographically determined posture, identified associated with measures spinal pain.Relatively little research has been performed toward a classification subjects according alignment. Clinical descriptions different classifications have reported, recently confirmed in radiographic study. There is limited...

Statistical Classification Model for nonspecific chronic low back pain (NS-CLBP) patients and controls based on parameters of motor control.Develop a to discriminate between 2 subgroups NS-CLBP (Flexion Pattern [FP] Active Extension [AEP]) control group using biomechanical variables quantifying control.It has been well documented that many CLBP have impairments their lumbar spine. O'Sullivan proposed mechanism-based classification system with comprehensive subjective physical examination...

Overweight or obesity during adolescence affects almost 25% of Australian youth, yet limited research exists regarding recruitment and engagement adolescents in weight-management healthy lifestyle interventions, best-practice for encouraging long-term behaviour change. A sound understanding community perceptions, including views from adolescents, parents stakeholders, barriers enablers to entering engaging meaningfully an intervention is critical improve the design such programs. This paper...

Computers are now widely used by children. Tablet computers becoming available and promoted for use school The primary objective of this study was to compare the posture muscle activity children using a tablet computer desktop paper technology. Eighteen (mean age 5.6 years) performed colouring-in task in tablet, conditions. 3-D around neck shoulder assessed. similar use, with less neutral spinal posture, more elevated scapular greater upper trapezius cervical erector spinae activity. This...

Occupational sedentary behaviour is an important contributor to overall risk. There limited evidence for effective workplace interventions reduce occupational time and increase light activity during work hours. The purpose of the study was determine if participatory could total time, sustained (bouts >30 minutes), frequency breaks in promote intensity moderate/vigorous (MVPA)

Office workers are exposed to high levels of sedentary time. In addition cardio-vascular and metabolic health risks, this time may have musculoskeletal and/or cognitive impacts on office workers. Participants (n = 20) undertook two hours laboratory-based sitting computer work investigate changes in discomfort function (sustained attention problem solving), along with muscle fatigue, movement mental state. Over time, increased all body areas (total IRR [95% confidence interval]: 1.43...

Objective: This study aimed to determine the effects of active workstation designs on speed and error during typing, mouse pointing, combined type mouse-use tasks. Background: Office ergonomics has focused musculoskeletal disorder prevention; however, increasing computer-based work also increases health risks associated with inactivity. Workstations allowing computer users walk or cycle while performing tasks have been shown demand sufficient energy expenditure result in significant...

Spinal posture is commonly a focus in the assessment and clinical management of low back pain (LBP) patients. However, link between spinal LBP not fully understood. Recent evidence suggests that considering regional, rather than total lumbar spine important. The purpose this study was to determine; if there are regional differences habitual movement, these findings influenced by LBP. One hundred seventy female undergraduate nursing students, with without LBP, participated cross-sectional...
