Wearable inertial measurement units (IMUs) are used increasingly to estimate biomechanical exposures in lifting-lowering tasks. The objective of the study was develop and evaluate predictive models for estimating relative hand loads two other critical gain a comprehensive understanding work-related musculoskeletal disorders lifting. We collected 12,480 phases from 26 subjects (15 men 11 women) performing manual tasks with (0-22.7 kg) at varied workstation heights handling modes. implemented

Buckwheat sprouts have been widely consumed all around world due to their great abundance of bioactive compounds. In this study, the anti‐inflammatory effects flavonoid‐rich common buckwheat sprout (CBS) and tartary (TBS) extracts were evaluated in lipopolysaccharide‐ (LPS‐) stimulated RAW 264.7 murine macrophages primary peritoneal from male BALB/c mice. Based on reversed‐phase HPLC analysis, major flavonoids CBS determined be C ‐glycosylflavones (orientin, isoorientin, vitexin,...

Construction is considered amongst the highest risk sectors for development of work-related musculoskeletal disorders (MSDs) considering large number unfavourable environmental and task-specific factors typical in this sector. Thus, it important to have quantitative tools support assessment exposure physical MSD factors. We employed wearable inertial sensors (ISs) perform a real-world characterisation static postures repetitive movements involving trunk upper arms (UA), among 15 workers...

Live-streamed group exercise programmes are used increasingly to start or maintain physical activity behaviours. However, participants' performance and long-term engagement can be impacted in live-streamed due communication gaps with the instructors peers. We analysed verbal nonverbal differences between in-person yoga classes understand current challenges programmes. A total of 29 class videos (14 15 in-person) were annotated for events. found significantly reduced individual feedback vs....

Industrial robots have become an important aspect in modern industry. In the context of human-robot collaboration, enabling teleoperated to work close proximity local/onsite humans can provide new opportunities improve human engagement a distributed workplace. Interviews with industry stakeholders highlighted several potential benefits such teleoperator-robot-human collaboration (tRHC), including application tRHC tasks requiring both expertise and manual dexterity (e.g., maintenance highly...

Engaging in regular physical activity offers a myriad of benefits, including the improvement mental health, social well-being, and cognitive function. Unfortunately, obstacles, such as transportation constraints, time limitations, inadequate exercise facilities, hinder participation older adults activity. Online group programs present promising solution to enhance involvement adults; however, several barriers impede their effective utilization. To explore these we conducted semi-structured...

Virtual reality (VR) has emerged as a promising tool for training novice forklift drivers, but temporal patterns of such improvements are largely unknown. We trained 19 participants using an order-picker VR simulator on selected driving lesson. In two sessions, participant performance was assessed task completion time and kinematics the head, shoulder, lumbar spine via inertial measurement units (IMUs). Completion head flexion/movement decreased significantly (up to 22.4% 31.5%,...

Virtual reality (VR) has emerged as a promising tool for training. Our focus was on training forklift driving, to address an ongoing worker shortage, and the unknown impact of repeated task performance kinematic adaptations. We trained 20 novice participants using VR simulator over two days, with trials each day three different driving lessons varying difficulties. Driving assessed lesson completion time, we quantified kinematics head, shoulder, lumbar spine. Repeated reduced time (up ~29.8%...

Manual carrying of heavy weight poses a major risk for work-related low back injury. Body-worn inertial sensors present opportunities to study the effects ambulatory work tasks such as load carriage in more realistic conditions. An immediate effect is reflected altered gait kinematics. To determine mode and magnitude on parameters using body-worn angular rate gyroscopes, two laboratory experiments (n = 9 n 10, respectively) were conducted. Participants performed walk trials at self-selected...

The mechanisms of action responsible for the reported hypolipidemic activity barley sprouts have yet to be elucidated. objective this study was compare content saponarin (the sole flavonoid present in sprout leaves), between water extract (BSW) and ethanol (BSE), associated relevance 3T3-L1 preadipocytes. BSW elicited superior antiadipogenic effects when compared with BSE MDI mixture [IBMX 0.5 mM + dexamethasone 1 μM insulin μg/mL]-treated attenuated MDI-mediated triacylglycerol (TAG)...

The objective of this study was to examine potential gender effects on the performance a statistical algorithm for predicting hand-load levels that uses body-worn inertial sensor data. Torso and pelvic kinematic data obtained from 11 men women in laboratory experiment while they carried anterior hand-loads 13.6 kg, 22.7 during unloaded walking. Nine variables expressed as relative changes gait were calculated used predictors classification model load-level (no-load, kg). To compare...

The objective of this study was to evaluate the performance machine learning (ML) algorithms developed using surface electromyography (EMG) armband sensor data in predicting hand-load levels (5 lb and 15 lb) from diverse lifting trials. Twelve healthy participants (six male six female) performed repetitive with three different conditions, i.e., symmetric (S), asymmetric (A), free-dynamic (F) lifts. ML models were four datasets (S, A, S+A, F) cross-validated F as test dataset. Mean...

This study explored the use of body posture kinematics derived from wearable inertial sensors to estimate force exertion levels in a two-handed isometric pushing and pulling task. A prediction model was developed grounded on hypothesis that postures predictably change depending magnitude exerted force. Five postural angles, viz., torso flexion, pelvis lumbar hip upper arm inclination, collected 15 male participants performing simulated tasks laboratory were used as predictor variables...
