Weight lifting in children and youth is often viewed as a potentially harmful activity that could result in damage to bones, connective tissue, and muscle. Reviews, such as the one appearing in this issue of the journal by Behm et al. (Appl. Physiol. Metab. Nutr. 33: this issue), show that the balance of evidence indicates that weight lifting in pediatric populations is safe. Importantly, weigh...

The occurrence of the size-weight illusion is related to the manner in which objects are lifted. When the SWI occurs, the larger of two objects of equal objective weight is usually lifted with greater acceleration, deceleration, and maximum velocity than the smaller one, but to approximately the same height. These differences are not present when the cans feel equally heavy. The relationship of...

OBJECTIVE To evaluate the effect of weight lifting on intraocular pressure (IOP). METHODS Subjects performed 4 repetitions of a bench press exercise in 2 ways: in mode I (right eyes), the breath was held during the last repetition; in mode II (left eyes), subjects exhaled normally during the last repetition. The IOP was measured with an electronic tonometer during the fourth repetition in bot...

The study established characteristics of practices and practitioners of leisure-time physical activities among adults in Florianopolis, Brazil. It was a population-based, cross-sectional survey conducted between September 2009 and January 2010. Leisure-time physical activity was assessed using a validated questionnaire. Walking and weight lifting were the most frequently reported activities. Vi...

STUDY DESIGN A cross-sectional study design was used. OBJECTIVE The objective was to examine the influences of body anthropometrics, axial disc area, and lifting strength on disc degeneration and to compare these with the effects of lifetime physical demands and age. SUMMARY OF BACKGROUND DATA Although recent studies have shown that heredity is a dominant factor in disc degeneration, the co...

— We construct a rigid-analytic map from the the author’s half-integral weight cuspidal eigencurve (see [10]) to its integral weight counterpart that interpolates the classical Shimura lifting.

We consider a reductive dual pair (G,G′) in the stable range with G′ the smaller member and of Hermitian symmetric type. We study the theta lifting of (holomorphic) nilpotent K ′ C -orbits in relation to the theta lifting of unitary lowest weight representations of G′. We determine the associated cycles of all such representations. In particular, we prove that the multiplicity in the associated...

OBJECTIVES To quantify the variability in lifting motions, trunk moments, and spinal loads associated with repeated lifting exertions and to identify workplace factors that influence the biomechanical variability. DESIGN Measurement of trunk dynamics, moments and muscle activities were used as inputs into EMG assisted model of spinal loading. BACKGROUND Traditional biomechanical models assu...

The lifting and carrying of loads in agriculture on small landholdings are unavoidable. Rural communities often lack access to appropriate technologies which may result in various health hazards. The objective was to study gender participation in agricultural activities involving manual material handling tasks, to assess MSDs experienced in various MMH tasks and to evaluate traditional method a...
