The Joint Commission provides accreditation standards for staging hospital waste, but there are no federal lifting safety standards for linen bags. We evaluated hospital laundry bag lifting using the Revised National Institute for Occupational Safety and Health (NIOSH) Lifting Equation. We hypothesized that the permitted 32-gallon linen container capacity might allow filling to weights above our calculated Recommended Weight Limit (RWL) for some lifting positions and contents. We found that 30- and 40-gallon bags filled with loose dry linen had predicted weights within estimated RWLs only for lifts close to the body...

Background: The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. Objective: to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Methods: Wistar male rats were divided into three groups: continuous exercise (CEx, 1 hour on the treadmill) or accumulated exercise (AEx, 4 bouts of 15 minutes / day) for 5 days/week for 8 weeks, or sedentary (SED)...

BACKGROUND: The necessity of sternal precautions for patients following cardiac surgery with median sternotomy has been questioned by clinicians, researchers, and even patients. The primary purpose was to determine if sternal skin deformation during shoulder movements and upper extremity activities is compressive or distractive and if there are any significant differences between the skin deformation at different positions during shoulder movements and upper extremity activities. The secondary purpose was to determine if sternal skin deformation is correlated with scapular stabilizer muscle strength...

Sergio Cesare Masin, Andrea Brancaccio
Experimental instructions to judge differences or ratios of subjective heaviness numerically are generally assumed to produce judgments linearly proportional to the respective heaviness differences or heaviness ratios. In this study, participants were instructed to numerically judge the difference or ratio of heaviness between two weights being lifted separately, either unimanually or bimanually. Weight values were combined factorially. Patterns of factorial curves revealed that unimanual lifting triggered linear judgments of heaviness differences, whereas bimanual lifting triggered nonlinear judgments of heaviness ratios...

Posterior branches of the lumbar spinal nerves are the anatomic substrate of pain in the lower back, sacrum and the gluteal area. Such pain may be associated with various pathologies which cause pain in the posterior branches of the lumbar spinal nerves due to entrapment, mechanical irritation or inflammatory reaction and/or degeneration. The posterior branches are of significant functional importance, which is related to the function of the structures they supply, including facet joints, which are the basic biomechanical units of the spine...

Weight loss is the cornerstone of therapy for people with obesity because it can ameliorate or completely resolve the metabolic risk factors for diabetes, coronary artery disease, and obesity-associated cancers. The potential health benefits of diet-induced weight loss are thought to be compromised by the weight-loss-associated loss of lean body mass, which could increase the risk of sarcopenia (low muscle mass and impaired muscle function). The objective of this review is to provide an overview of what is known about weight-loss-induced muscle loss and its implications for overall physical function (e...

Yiyun Lan, Jun Yao, Julius P A Dewald
BACKGROUND: Up to 60% of individuals with moderate to severe chronic hemiparetic stroke experience excessive involuntary wrist/finger flexion that constrains functional hand movements including hand opening. It's not known how stroke-induced brain injury impacts volitional hand opening and grasping forces as a result of the expression of abnormal coupling between shoulder abduction and wrist/finger flexion or the flexion synergy. OBJECTIVE: The goal of this study is to understand how shoulder abduction loading affects volitional hand opening and grasping forces in individuals with moderate to severe chronic hemiparetic stroke...

Morgan L Waddell, Eric L Amazeen
Perceived heaviness is clearly a function of muscle activity: objects feel heavy, in part because they are lifted with more force than lighter feeling objects. Recent research showed that participants scale their perceptions to the ratio of muscle activity to lift acceleration during elbow lifts (Waddell et al. J Exp Psychol Hum Percept Perform 42:363-374, 2016). The current study sought psychophysiological functions relating perceived heaviness to EMG and peak lift acceleration across multiple lifts employing different muscles as prime movers...

REVIEW
Per A Tesch, Rodrigo Fernandez-Gonzalo, Tommy R Lundberg
In the quest for a viable non-gravity dependent method to "lift weights" in space, our laboratory introduced iso-inertial resistance (YoYo™) exercise using spinning flywheel(s), more than 25 years ago. After being thoroughly tested in individuals subjected to various established spaceflight analogs, a multi-mode YoYo™ exercise apparatus was eventually installed on the International Space Station in 2009. The method, applicable to any muscle group, provides accommodated resistance and optimal muscle loading through the full range of motion of concentric actions, and brief episodes of eccentric overload...

Liman Yang, Langfu Cui, Yunhua Li, Chao An
Metal roof sheathings are widely employed in large-span buildings because of their light weight, high strength and corrosion resistance. However, their severe working environment may lead to deformation, leakage and wind-lift, etc. Thus, predicting these damages in advance and taking maintenance measures accordingly has become important to avoid economic losses and personal injuries. Conventionally, the health monitoring of metal roofs mainly relies on manual inspection, which unavoidably compromises the working efficiency and cannot diagnose and predict possible failures in time...

Jianpeng He, Steve Dixon, Samuel Hill, Ke Xu
Electromagnetic acoustic transducers (EMATs) are non-contact, ultrasonic transducers that are usually kept within 5 mm from the sample surface to obtain a sufficient signal-to-noise ratio (SNR). One important issue associated with operation on a ferromagnetic plate is that the strong attraction force from the magnet can affect measurements and make scanning difficult. This paper investigates a method to generate fundamental, symmetric Lamb waves on a ferromagnetic plate. A coil-only, low-weight, generation EMAT is designed and investigated, operating at lift-offs of over 5 mm...

This research investigates the prevalence of human osteoarthritis at Yinxu, the last capital of the Late Shang dynasty (ca. 1250-1046 B.C.), to gain insights about lifeways of early urban populations in ancient China. A total of 167 skeletal remains from two sites (Xiaomintun and Xin'anzhuang) were analyzed to examine osteoarthritis at eight appendicular joints and through three spinal osseous indicators. High osteoarthritis frequencies were found in the remains with males showing significantly higher osteoarthritis on the upper body (compared to that of the females)...

PURPOSE: To determine if muscle growth is important for increasing muscle strength or if changes in strength can be entirely explained from practicing the strength test. METHODS: Thirty-eight untrained individuals performed knee extension and chest press exercise for 8 weeks. Individuals were randomly assigned to either a high-volume training group (HYPER) or a group just performing the one repetition maximum (1RM) strength test (TEST). The HYPER group performed 4 sets to volitional failure (~8-12RM) while the TEST group performed up to 5 attempts to lift as much weight as possible one time each visit...

In vitro and in vivo studies described the myokine IL-15 and its receptor IL-15Rα as anabolic/anti-atrophy agents, however the protein expression of IL-15Rα has not been measured in human skeletal muscle and data regarding IL-15 expression remain inconclusive. The purpose of the study was to determine serum and skeletal muscle IL-15 and IL-15Rα responses to resistance exercise session and to analyse their association with myofibrillar protein synthesis (MPS). Fourteen participants performed a bilateral leg resistance exercise composed of 4 sets of leg press and 4 sets of knee extension at 75% 1RM to task failure...

It is not known whether, during the course of ageing, changes occur in the motor strategies used by the CNS for lifting objects of different weights. Here, we analysed the kinematics of object-lifting in two different healthy groups (young and elderly people) plus one well known deafferented patient (GL). The task was to reach and lift onto a shelf an opaque cylindrical object with changing weight. The movements of the hand and object were recorded with electromagnetic sensors. In an ecological context (i.e...

Jack Brooks, Anne Thaler
A reliable mechanism to predict the heaviness of an object is important for manipulating an object under environmental uncertainty. Recently, Cashaback et al. (Journal of Neurophysiol 117: 260-274, 2017) showed that for object lifting, the sensorimotor system uses a strategy that minimizes prediction error when the object's weight is uncertain. Previous research demonstrates that visually guided reaching is similarly optimised. Although this suggests a unified strategy of the sensorimotor system for object manipulation, the selected strategy appears to be task dependent and subject to change in response to the degree of environmental uncertainty...

BACKGROUND AND OBJECTIVE: Cardiorespiratory responses and symptoms in response to endurance exercise in patients with COPD vary with the number and position of involved limbs. Responses to such variations have never been quantified for strength exercises. We therefore assessed acute cardiorespiratory responses during brief bouts of weight lifting exercises. METHODS: We compared double- versus single-limb leg extensions and arm elevations, as well as arm elevation done above or below shoulder level in patients with moderate to severe COPD (n = 10, 6 males, 66 (8...
