The aim of this work: to evaluate the body composition, aerobic endurance, working memory and their relations among female students. The goals of this work: 1) to evaluate the aerobic endurance of female students; 2) to examine the body composition of female students; 3) to evaluate the working memory of female students; 4) to determine relations between aerobic endurance, body composition and working memory among students. The methods of the research: the research was carried out from October 2016 to February 2017. During the research students completed a questionnaire about their hobbies, state of health and physical fitness. 30 female physiotherapy students of Faculty of Medicine at Vilnius University participated in the examination. Students‘ body composition was evaluatedusing body composition analyzer ,,Jawon IOI-353‘‘; aerobic endurance was evaluated instantly using cycle ergometer and Oxygen analyzer; cardiovascular system‘s functional index was tested by Ruffier test. The working memory of the examinees was tested while executing working memory test. Analysis of statistical data was accomplished using the programmes of statistical analysis: ,,MS Office Excel 2010“, „SPSS 2.0.2.“. Level of credibility is 0,05. Results: The body mass index of the examinees corresponded to normal range (p<0,05). Average VO2 max equals 40,10±5,78 ml/kg/min. Statistically significant difference of maximal oxygen uptake and maximal heart rate after physical load was discovered (p<0,05). Average Working memory equals 76±0,06 percent and 50±0,07 percent. Strong correlation between the body mass index and the maximal oxygen consumption was discovered (r= -0,707; p<0,05). Statistically significant average correlation between students‘ body composition and heart rate after aerobic load was discovered (r=0,5; p<0,05). Students‘ aerobic endurance and working memory correlated poorly (r=-0,426; p>0,05) while relations between body composition and working memory was not discovered (r=0; p>0,05). Conclusions: 1.The average body mass index of the students was 20,28±2,04 kg/m2 and it fitted the range recommended by World Health Organization. 2.The aerobic endurance of 19 students‘ fitted in the range between average and inferior level while the aerobic endurance of 11 students was higher than the normal range. 3. None of the students achieved the maximal results of the working memory tests. It was determined that the results of working memory tests 25 % better than those of mental rotation. 4. A statistically significant strong correlation between students‘ body mass and VO2 max was found (p<0,05). The body composition and heart rate after aerobic load related in statistically significant average correlation. The students‘ aerobic endurance and working memory correlate poorly, while relations between body composition and working memory were not discovered. |
