    Opis:
    Health status is partly determined by physical fitness level. Physical fitness can be developed through different physical activities under condition that regularity and intensity are maintained on optimal level. One of such physical activities is step aerobics - one of the most popular collective fitness forms offered in fitness clubs. The objective of this study was to evaluate the influence of step aerobics training on VO2max, isometric strength and body composition of young female students. Female students aged 19-21 of University of Physical Education and Sport in Gdańsk were subjects in this study. VO2max, isometric strength of elbow flexors and knee extensors, as well as body composition, were measured week before and week after a ten-week step aerobics training. For statistical analysis, basic descriptive statistics and student’s t-test were applied for dependent variables. After ten weeks of training there were no statistically significant changes in body composition, probably due to lack of calorie intake control. Significant changes were observed in isometric strength of elbow flexors but no changes in isometric strength of knee extensors. There was a compensation in isometric strength noted between left and right leg after ten weeks of training, where left leg was weaker than the right leg before training. Significant changes were noted in VO2max values, which increased from 42.04 ml/kg/min-1 to 45.71 ml/kg/min-1. Step aerobics training can sufficiently increase VO2max in young females and has a potential in developing strength of upper extremities. When body composition is the main purpose, diet should be taken under consideration.

    Opis:
    The aim of this study was to determine what proportion of occupationally active Poles have working capacity that enables them to tolerate hard and very hard physical work. For this purpose physical capacity of 1188 occupationally active subjects (524 women and 664 men), aged 18–64 years was examined. Their maximal oxygen consumption (VO2max) was determined indirectly on the basis of their heart rate during an incremental exercise test on a bicycle ergometer. It was found that hard occupational physical work was an excessive load for almost 40% of men and women. This paper discusses how this load should be decreased with planned, appropriately long rest breaks. The percentage of persons for whom their hard physical work becomes an excessive load increases with age to such a degree that a new assessment of individual capability for such work is recommended for persons over 40 years old.

    Opis:
    This study is aimed at analysing the variability of oxygen parameters in subsequent annual training cycles at championship training level in mountain running. The study employed the following indirect methods: the Astrand Test, Conconi Running Test, and also a direct method (Bruce Test). Research material is a young, talented 28-year-old athletic mountain runner. Research results were obtained within 4-5 years period, which were as follows: VO2max 83-90ml/kg/min - increased on average to 2-3 ml / kg / min per year, HR max 172-177 beats / min, PPA 158-169 beats / min. The case study was carried out within the framework of longitudinal research and was used to collect data for the formulation of a specific exercise profile in a new, dynamic sports discipline. The research aims to serve as an example of a novel method of conducting training microcycles to the cyclic lifting aerobic capacity athletes.

    Opis:
    Introduction. The aim of this study was to estimate maximal aerobic capacity (VO2 max), to determine its associated factors among workers of industrial sector of Iran and to develop a regression equation for subjects’ VO2 max. Methods. In this study, 500 healthy male workers employed in Shiraz industries participated voluntarily. The subjects’ VO2 max was assessed with the ergocycle test according to the Åstrand protocol. Required data was collected with a questionnaire covering demographic details (i.e., age, job tenure, marital status, education, nature of work, shift work, smoking and weekly exercises). Results. The subject’s mean VO2 max was 2.69 ± 0.263 l/min. The results showed that there was an association between VO2 max and age, BMI, hours of exercise and smoking, but there was no association between VO2 max and height, weight, nature of work and working schedule. On the basis of the results, regression equations were developed to estimate VO2 max. Conclusion. Final regression equation developed in this study may be used to estimate VO2 max reliably without the need to use other laboratory instruments for aerobic measurement.

    Opis:
    Background. The aim of the study was to find physical discriminants in Polish senior league elite boxers Material and methods. 13 competitors from the senior national team of average age and body mass participated in the study. The applied methods of assessment included FMS and CMJ tests, 3kg medicine ball throw and 1200m shuttle run. Results. Statistical analysis of the studied biomechanical variables compared with the results of the Polish Senior Championships and the yearly rank list did not reveal any significant correlation. Conclusions. The lack of a clear physical indicator may indicate that the determinants of success in sports depend on other competitors’ traits. On the other hand, the small sample size may be the reason of the lack of statistical significance. An adequate level of physical capacities may allow effective use of the athlete’s vast potential, however, it is not the only decisive factor affecting success in boxing.
    Wstęp. W pracy poszukiwano fizycznych wyróżników jakimi charakteryzowali się najbardziej utytułowani zawodnicy polskiej kadry narodowej seniorów. Materiał i metody. 13 zawodników kadry narodowej seniorów w średnim wieku i masie ciała. Wykonano test FMS, CMJ, rzut piłką lekarską 3 kg, bieg wahadłowy 1200 m. Wyniki. Analiza statystyczna badanych zmiennych biomechanicznych oraz wyników podczas Mistrzostw Polski Seniorów oraz roczną listą rankingową nie wykazała istotnej zależności. Wnioski. Brak jednoznacznego fizycznego wskaźnika może świadczyć, iż determinantów sukcesu sportowego należy szukać także w innych cechach zawodnika. Z drugiej strony niewielka liczebność próbki odpowiada za brak istotności statystycznej. Odpowiedni poziom zdolności fizycznych może pozwolić na efektywne wykorzystanie szerokiego potencjału sportowca, ale nie jest jedynym i decydującym czynnikiem wpływającym na sukces w boksie.

    Opis:
    The aim of this study was to determine the relationship between age, aerobic capacity (VO2 max) and other health indicators among 3 rescue groups. The type of training and the subjective perception of physical fitness obtained via the Assessment Questionnaire of Physical Fitness were also analysed. To obtain VO2 max, 37 firefighters, 22 lifeguards and 59 mine rescue workers had a treadmill test. Their body mass index and body fat percentage were also calculated. The results show a significant decline in VO2 max of the older participants, which affects the effectiveness of rescue work. Furthermore, the training of all groups was inconsistent and based on individual needs. Variable training and the decline in VO2 max with age affected the effectiveness of the rescue tasks of each group.
