The effect of non-weight-bearing exercise and protein intake during pregnancy on maternal and fetal zinc content in the Sprague-Dawley rat
To study the effect of exercise and protein intake during pregnancy on maternal and fetal zinc status in the rat, one hundred and seventy-nine pregnant Sprague-Dawley rats were divided into four groups; sedentary-standard protein diet, sedentary-high protein diet, exercising-standard protein diet …

The Relationship between Dorsiflexion Range of Motion and Knee Kinematics in a Land-and-Jump Task
<p>The study examined the relationship between weight-bearing and non weight-bearing dorsiflexion range of motion and frontal knee kinematics at initial ground contact and maximal knee flexion in a land-and-jump task. Thirteen male participants (age = 23 + 2.35 y, height = 181.4 + 5.68 cm, mass = …

The effect of long term training on the bone mineral density and muscle strength of perimenopausal athletes
… long term training (20 years+) in a high impact weight bearing sport (netball/basketball: NB/88), a low impact weight-bearing sport (running/ field hockey: GEN) and a non weight-bearing sport, swimming (SWI) produced a positive relationship with regional bone mineral density (BMD) and muscle …

In vivo Sub-regional dGEMRIC Analysis and Contrast Distribution in Clinical Studies of Human Knee Cartilage
… Gd concentration in the superficial layer of weight-bearing cartilage in elite runners, than in sedentary individuals. More contrast agent seen in superficial non-weight-bearing cartilage than weight-bearing cartilage. In Study III, those who increased their physical activity showed a …

Musculoskeletal adaptation to Partial Weight Suspension : studies of Lunar and Mars loading
… effects of this novel environment. In the weight bearing structures of the body, bone loss and muscle atrophy far in excess of age-related declines are hallmarks of microgravity adaptation. However, while the physiological effects of such disuse unloading are well-described, the effects of …

Surface electromyography of facilitated versus free arm activation after stroke
… unassisted attempts at flexion and extension, weight bearing attempts through the arm, and therapist resistive facilitation. The results show that weight bearing and facilitation result in greater muscle activation, even in patients with fully paretic arms. Possible applications of this effect …

Osteoarthritis and ultra-distance marathon running
… loading on the articular cartilage of the large weight bearing joints (hip, knee, and ankle joints) during distance running might be a potential precipitating factor in OA. The aim of this case-control study was to investigate the relationship between total accumulated running volume and OA in …

The design and cadaveric assessment of a new artifial first metatarsophalangeal joint replacement for the great toe
… that FMTPJ prostheses fail to restore normal weight-bearing. In this regard, FMTPJ arthroplasties perform little better than amputation. The reasons for the poor biomechanical performance of FMTPJ arthroplasty are not well documented. Existing theoretical models of FMTPJ function cannot be …

Girl Scouts Empower Other Girl Scouts to Consume 3-A-Day™ of Dairy
… about the importance of calcium intake and weight-bearing activities in the prevention of osteoporosis, overweight, and hypertension. Peer educators had significant increases in their overall knowledge of dairy (p<0.001) and self-efficacy related to 3-A-Day™ (p<0.05) after teaching peer …

Osteonecrosis: Cape wine as an aetiological agent
… resulting in the destruction of major weight-bearing joints requiring arthrodesis or arthroplasty. A decade ago it was hoped that joint replacement would solve most of these problems, however, failure of such arthroplasties have often been associated with catastrophic consequences …

The impact of dynamic and passive standing on bone mineral density and appositional growth in immobilized children
… and researchers to investigate the impact of weight-bearing interventions on individuals with an increased risk of osteoporosis. The most common weight-bearing clinical intervention used in non-ambulant populations is passive standing. However, insurance companies are increasingly denying …

Criterion validity of selected Wii Fit™ games for balance assessment
… The Basic Balance Master® variables included the Weight Bearing Symmetry, Limit of Stability-directional control, Limit of Stability-maximum excursion, Rhythmic Weight Shift-directional control lateral, and Rhythmic Weight Shift-directional control antero-posterior. The data were analyzed using a …

A Comparison of Strength, ROM, Laxity, and Dynamic and Static Postural Control Between Those At-Risk and Healthy
… the SEBT-A, a single-lag balance task, the Weight Bearing Lunge Test (WBLT), concentric strength of sagittal-plane ankle and knee movers using the Biodex, and ankle laxity using an instrumented ankle arthrometer. Main Outcome Measures: The normalized reach distance of the SEBT-A was …

The intersection of pain, disease severity, and circadian disruption in experimental autoimmune encephalomyelitis
… an observer-independent assay, advanced dynamic weight bearing (ADWB), was investigated as a tool for monitoring disease progression in EAE. ADWB was shown to accurately detect shifts in weight bearing as EAE mice developed locomotor dysfunction in the hindlimbs. Third, circadian rhythms were …

Development of a mouse model for the study of osteoarthritis pain
… manner. Pain was assessed by monitoring weight bearing, mechanical hyperalgesia, cold allodynia, mechanical allodynia and vocalisation in response to knee compression for 12 weeks post-surgery. No significant weight bearing deficits were observed during the course of the study. …

Morphometric study of long bones histology
… parameters are not only found within weight bearing bones, but are also demonstrated in non-weight bearing skeletal elements. Second, the existence of this variation is considerable and should be taken into account when utilising histological methods in a forensic context, especially …

Histological age estimation of the midshaft clavicle using a new digital technique.
… was chosen as a sample site since it is not a weight bearing bone and has little muscular insertion. These factors reduce the variation seen as a result of differences in lifestyle or activity pattern.

Upper extremity vertical ground reaction forces during the back handspring skill in gymnastics: A comparison of various braced vs. unbraced techniques
… common mechanism of repetitive hyperextension in weight bearing among gymnasts of all ages. Many gymnasts use wrist supports as prevention; however, literature regarding their ability to reduce injury is not well described. The purpose of this study is to evaluate the effects of Tiger Paw wrist …
