OBJECTIVE: The aim of this study was to verify the use of the spectral analysis of heart rate variability (SA HRV) method as a tool for classification of the answer of the body to both the rapid transition across time zones and the training intensity level during the following acclimatization. METHODS: Changes in autonomic activity were assessed by SA HRV during acclimatization after eastward (+6 hours) and westward (–7 hours) flights in two elite athletes. RESULTS: The results revealed that the athlete, who undertook a flight from Prague to Beijing (China), was able to start with intensive training during the fourth day of his acclimatization. No acute decrease in training ability (adaptability) was found in the athlete after the flight from Prague to Bogo...

This study aims to elucidate the current state of and trends in pupils’ assessments of physical education lessons (PELs) in different education systems in the context of self-perception of physical fitness. The research was conducted during PELs taught by student teachers at primary schools and high schools in the Czech Republic and in Poland. Schools were selected annually between 2000 and 2011 according to the student teachers’ places of residence. In total, the research involved 25,988 Czech pupils and 21,205 Polish pupils. At the end of each PEL, an anonymous questionnaire was distributed. The Czech and Polish versions contained cognitive, emotional, health, social, attitudinal, and creative dimensions and the supplementary dimension “pupil’s role”. For the analysis, pupils were divided according to their self-perceived...

The seven-year-long international study involved 670-850 university students annually. Students participated directly in the research activities that were in compliance with the curricula of sport education study programs. The presented educational model describes possibilities and major limits how to provide dozens evidence-based knowledge of prospective sport professionals in the areas of physical activity monitoring, self-assessment of physical fitness and evaluation of sport preferences.
