Trauma is one of the very frequent interactions of an individual with the environment. Czech authors dealing with trauma in the area of biomechanics are e.g. Jelen (1991), Karas (1996), Turková (1997) and others. Injuries in general, and especially injuries of pregnant women are an important theme in a society – e.g. car injuries representing two thirds of all traumas during gestation are linke...

Several factors can impact lumbosacral loads during lifting, including weight knowledge and weight magnitude. However, interaction between them has never been tested. This study investigated the interaction effect of these variables on lumbosacral forces and moments. Participants performed symmetrical lifts using three different weights. Weight knowledge involved known and unknown weight condit...

OBJECTIVES To assess the effects of differing impact exercise protocols on postmenopausal bone loss at the hip and spine. DESIGN Systematic review and meta-analysis. DATA SOURCES Electronic bibliographic databases, key journals and reference lists of reviews and articles. REVIEW METHODS Two independent reviewers assessed controlled trials evaluating effects of impact exercise on lumbar sp...

The theory of electron impact ionization of oneand two-electron atoms has advanced significantly in the past two years. This paper will summarize the progress that the members of our research center have contributed to.
