This study examined the effects of 3 lifting ranges and 3 lifting modes on maximum lifting capability and total lifting time. The results demonstrated that the maximum lifting capability for FK (from floor to knuckle height) was greater than that for KS (from knuckle height to shoulder height) or FS (from floor to shoulder height). Additionally, asymmetric lifting with initial trunk rotation de...

In Western culture there are countless examples of reference to female legs as a factor in sexual attraction. It is not surprising, therefore, that both males and females perceive female figures as more attractive as leg length increases, in proportion to torso or stature, and perhaps the opposite should be true for male figures. Both evolutionary and sociocultural factors can play a role in th...

CONTEXT Control of the trunk segment in landing has been implicated as a contributing factor to the higher incidence of anterior cruciate ligament injuries in females than in males. Investigating the sex-specific abdominal activation strategies during landing lends insight into mechanisms contributing to control of the trunk segment. OBJECTIVE To examine the abdominal activation strategies us...

The authors explored how trunk compensation and hand symmetry in stroke survivors and healthy controls were affected by the distance and height of virtual targets during a bimanual reaching task. Participants were asked to reach to 4 different virtual targets set at: 90% of their arm length at shoulder, xiphoid process, and knee height, and 50% of their arm length at xiphoid process height. For...

The patterns of association between maternal or paternal and neonatal phenotype may offer insight into how neonatal characteristics are shaped by evolutionary processes, such as conflicting parental interests in fetal investment and obstetric constraints. Paternal interests are theoretically served by maximizing fetal growth, and maternal interests by managing investment in current and future o...

Objective: Validity of self-reported height and weight has not been adequately evaluated in diverse young populations. This study aims to examine the accuracy of self-reported weight, height, and BMI values in Spanish university students, as well as related factors that may determine the BMI in such population. Methods: Weight and height were self reported and measured in 68 university students...

Front load carriage is a common occupational task in some industries (e.g. agriculture, construction), but, as compared to lifting tasks, relatively little research has been conducted on the biomechanical loading during these activities. The focus of this study was to explore the low back biomechanics during these activities and, specifically, to examine the effects of load height and walking s...
