Background. Adequate nutrition and energy intake play key rule during the training period and recovery time. The assessment of athlete’s energetic needs should be calculated individually, based on personal energy expenditure and Sense Wear PRO3 Armband (SWA) mobile monitor is a useful tool to achieve this goal. However, there is still few studies conducted with use of this monitor. Objectives. To assess individual energy needs of athletes by use of SWA and to determine whether their energy intake fulfils the body’s energy expenditure. Material and Methods. Subjects were 15 male students attending Military University of Technology in Warsaw, aged 19-24 years, practicing aerobic. The average body mass was 80.7 ± 7.7 kg and average height was 186.9 ± 5.2 cm, (BMI 23.09 ± 1.85 kg/m2). Assessment of physical activity and energy expenditure (TEE) was established using SWA, which was placed on the back side of dominant hand and worn continuously for 48 hours (during the training and non-training day). The presented results are the average values of these 2 days. Assessment of athletes’ physical activity level was established by use of metabolic equivalent of task (MET) and number of steps (NS). Estimation of energy intake was based on threeday dietary recalls (two weekdays and one day of the weekend), evaluated using the Polish Software ‘Energia’ package. Results. The average TEE of examined athletes was 3877 ± 508 kcal/day and almost half of this energy was spend on physical activity (1898 ± 634 kcal/day). The number of steps was on average 19498 ± 5407 and average MET was 2.05 ± 2.09. The average daily energy intake was 2727 ± 576 kcal. Conclusions. Athletes consumed inadequate amount of energy in comparison to their energy expenditure. Examined group did not have an adequate knowledge about their energy requirement, which shows the need of nutritional consulting and education among these athletes.

Background: The aim of the research was to determine an influence of an increased number of outdoor lessons of Physical Education on aerobic fitness and to evaluate students’ attitude towards endurance efforts. Material/Methods: In the presented research project a group of students participated in a school program of Physical Education on the basis of a higher number of lessons realized in the natural environment in the vicinity of school. The subjects were a group of 220 students from 4 schools of the Pomeranian Voivodeship, who were subjected to initial and final measurements during two school years. The most important assumption of the research stated better effects of outdoor classes of Physical Education in comparison with indoor classes and the shortage of experimental factor influence on the correlation change between objective and subjective indices of fitness and attitudes related to it. Results: In the experimental group the most distinct differences between initial and final tests concerned the endurance measurement, similarly to the control group in which, however, the improvement in the final test was less noticeable. The correlation among three analyzed variables was significant for both research groups. The comparison of results of students from the experimental and the control groups demonstrates a positive influence of outdoor lessons on the level of endurance and, to a lower degree, on the feeling of effort fatigue and mood. Conclusions: The research was conducted with a use of three research tools: the mood scale, Cooper’s test and the subjective fatigue feeling with finished effort scale that allow a positive verification of the presented hypothesis, which should be an encouragement for wider practicing of innovative activities to bring closer the assumed aims of Physical Education to the aims actually achieved.
