摘要:The aim of the study was to create the basis according to content analysis of many previous studies which focused on the chronotype′s problem and personal features. The basis and information sources are important to realize a research which is aimed to verify the relationship between the chronotype and personal features of people who are interested in sport and they do it regularly and also of people who are not interested in any sport. The challenge is a question of confirmation of the chronotype′s impact on realisation of sport or work activities in sport and general life during the day in term of diurnal and circadian rhythms. It is important to detect and verify an assumption that specific kind of chronotype has really impact on the human being′s psychological, work and sport activity. Also, we want to detect and show the chronotype′s impact on selected determinants of health which can show positive aspects in human- being′s sport practice or everyday life by the specific application and the specific usage. If all assumptions and preconditions about chronotype's impact on work or sport in their suitable and complying time intervals are confirmed, it will also confirm the other important factor which makes our work more effective – time. This factor also respects the health of each human being. In other useful researches it would be suitable to correlate results of Clooninger′s tridimensional personality questionnaire with questionnaire which is specialized on chronotype′s identification (Horne & Ostberg, 1976). It would be very interesting to detect by the correlation of mentioned questionnaires- if people who tend to be the morning chronotypes (in different age groups) are characterized by more positive psychological features and traits than people characterized by the evening chronotype
