The human organism deprivation due to hypokinesis poses a threat to post-industrial society. The deprivation has its origin in fixed hypokinetic monotonous routines and stereotypes of modern man. This fact refers to the increase in the sensitivity level of proprioception, and therefore the reduction of tolerance to mechanical environmental loading. The preventive measures must be identified and rectified on the basis of both technical (personal protective equipment, forensic procedures, etc.) and sociobiological aspects (health and activity regimes, training, education, kinesiotherapy, etc.).
There is circumstantial evidence that suggests the possibility of resulting degenerative changes which have the cumulative and frequently irreversible effect, for example, structural changes in bone, muscle and cartilaginous tissues also cause a shift in rheological properties.
The impact on functional and processual system is not fully understood yet (decrease of sensorimotor performance and reliability, decision-making ability failure, etc.). The failure of psychomotor reactions at work environment – especially man-machine interactions also belongs to the above mentioned group.
In this critical review the structural and functional issues are discussed at three levels: at the scale of single tissue and organs, organ systems, and finally, at the supreme scale – whole organs. The difficulty of discovering and defining the explicit identifiers which describe the consequences of hypokinetic activity for the human organism lies in the complexity of the problem.

This monography will surely become required reading by students, teachers and everyone interested in biomedical and movement studies. The Czech Society of Biomechanics (CSB) and Charles University of Prague (FTVS) have made an excellent choise for collecting comprehends and thematic survey of results of an interdisciplinary reasearch of biomechanical reflexion of hypokinetical loads of human and their identifications. Many authors from CSB and FTVS contributed to the monography. Monography is devided into 2 very promised and interesting chapters (Functional consequences of hypokinetics and Structural consequences of hypokinetics). As it was written by editor-in-chief, assoc.prof. Karel Jelen, the research activities concerne biomechanical applications in understanding the influence of hypokinetics on human body. The authors have managed to collect all the up-to-date knowledge about above-mentioned topics. The publication consists of a survey of results obtained in past years (Project No. GACR P407/10/1624) from the project named »ldentifikace limitních účinků hypokinetické environmentální zátěže na spolehlivost senzomotorických reakcí človeka«.

The monography provides a fascinating previous and up-to-date overview account about the knowledge of functional and structural consequences of hypokinetics. This monography and more earlier already published, find an important place in the field of biomechanics. It is being refreshing to read all the chapters where can be find very positive and critical discussion of the actual and potential clinical and research values. This would be an appropriate publication to mark the society and university activities.
