Although patient handlers suffer from low-back injuries at an alarming rate worldwide, there has been limited research quantifying the risk for the specific tasks performed by the patient handlers. The current study used both a comprehensive evaluation system (low-back disorder risk model) and theoretical model (biomechanical spinal loading model) to evaluate risk of LBD of 17 participants (12 ...

Increasing axle loads of today’s North American heavy haul freight trains have presented numerous engineering challenges for the design and performance of concrete crossties and fastening systems. Several research studies have been conducted to understand the path of the vertical load from the wheel/rail interface through the fastening system and into the crosstie with successful results. Howev...

The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy w...

This study investigates the impact of future climate change on heavy metal (i.e., Cd and Zn) transport from soils to surface waters in a contaminated lowland catchment. The WALRUS hydrological model is employed in a semi-distributed manner to simulate current and future hydrological fluxes in the Dommel catchment in the Netherlands. The model is forced with climate change projections and the si...

Manual material handling is common in supermarkets and may be a contributing factor to the high prevalence of work-related musculoskeletal disorders, particularly lower back. This cross-sectional study applied state-of-the-art models driven by kinematic data obtained two estimate joint reaction forces knees, shoulders lumbar spine under dynamic lifting conditions. Based on 1479 lifts from 15 wo...

PURPOSE Despite a paucity of evidence, prevention guidelines typically advise avoidance of heavy lifting in an effort to protect against breast cancer-related lymphedema. This study compared acute responses in arm swelling and related symptoms after low- and heavy-load resistance exercise among women at risk for lymphedema while receiving adjuvant taxane-based chemotherapy. METHODS This is a ...

In the following experimental study the ability of normal and partially hepatectomized rats to clear their bloodstream of epinephrine-induced lactic acid loads was compared. As reported previously, significant differences in the handling of these loads were observed, and additional studies were carried out comparing the effect of carbon tetrachloride poisoning and bile duct ligation on the rat ...

Training at a load maximizing power output (Pmax) is an intuitively appealing strategy for enhancement of performance that has received little research attention. In this study we identified each subject's Pmax for an isoinertial resistance training exercise used for testing and training, and then we related the changes in strength to changes in sprint performance. The subjects were 18 well-tra...

Meat processing is a labor-intensive industry dealing with manual handling of heavy loads of meat at high frequency. Meat processing workers are under pressure to maintain high rates of work, performing arduous repetitive motions while keeping awkward postures. Ergonomic risk assessments reveal that manual material handling and repetitive tasks expose meat-processing workers to high physical ri...

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by tw...
