PURPOSE The effects of resistance training programs on strength, power, and military occupational task performances in women were examined. METHODS Untrained women aged (mean +/- SD) 23 +/- 4 yr were matched and randomly placed in total- (TP, N = 17 and TH, N = 18) or upper-body resistance training (UP, N = 18 and UH, N = 15), field (FLD, N = 14), or aerobic training groups (AER, N = 11). Two...

In this paper we present a system that supports users in retrieving data in distributed and heterogeneous archives and repositories. The architecture is based on the metaphor of the software agents and incorporates innovative hints from other elds: distributed architectures, relevance feedback and active interfaces. The system has a cooperative and supportive role: it understands the user's nee...

This paper proposes structural and parametric enhancements in the Timed Influence Nets (TINs) based framework for modeling Effects-Based Operations (EBO). The existing TIN framework does not have the capability to model the impact of different sequences of actions. Thus, no matter what the sequence of action is, the final outcome remains the same. Furthermore, it is assumed that the influence o...

This article examines the types of forces that the brain is subjected to in soccer, secondary to both acute brain injury and repetitive heading of the ball. The incidence of acute brain injury is reviewed, as well as studies documenting the effects of heading the ball. Finally, 10 actions are proposed that would make soccer a safer sport with respect to brain injuries and provide avenues for fu...

Chronic tendinopathies represent a major problem in the clinical practice of sports orthopaedic surgeons, sports doctors and other health professionals involved in the treatment of athletes and patients that perform repetitive actions. The lack of consensus relative to the diagnostic tools and treatment modalities represents a management dilemma for these professionals. With this review, the pu...

PURPOSE Among other etiologic factors involved in first carpometacarpal (CMC) osteoarthritis (OA), occupational factors have been postulated as influencing the occurrence of this condition. Very few epidemiologic studies, however, have evaluated this topic. Determining the occupational risk factors is important in proposing preventive measures at the workplace. This case-control study was under...

OBJECTIVES To determine, in a population based study, the influence of occupational factors on the occurrence of shoulder pain and disability. METHODS A random sample of patients was selected from the register of a general practice in the Greater Manchester area of the United Kingdom. Information was collected by a posted questionnaire with specific enquiries about symptoms in the shoulder re...

Occupational low back pain (LBP) is an immense burden for both industry and medicine. Ergonomic and personal risk factors result in LBP, but psychosocial factors can influence LBP disability. Epidemiologic studies clearly indicate the role of mechanical loads on the etiology of occupational LBP. Occupational exposures such as lifting, particularly in awkward postures; heavy lifting; or repetiti...

BACKGROUND Musculoskeletal disorders are the most frequent occupational diseases in Europe. However, their multifactorial aetiology poses several challenges concerning not only the estimation of relative prevalence rates across occupational groups but also how the co-occurrence of known risk factors might differ between disorders of the upper and lower limbs. Against this background, the follow...
