Opis:
Introduction. Physical fitness is a resultant of the efficiency of adaptive mechanisms for physical effort. People with intellectual disabilities may exhibit limited adaptive capacities, not only regarding their mental development, but also physiological, social and emotional development. Dysfunctions of the central nervous system observed in individuals with intellectual disabilities cause difficulties in gaining movement experience as well as problems with coordination and kinesthetic sense. Thus, intellectual disability might cause low physical activity and, consequently, low physical fitness. Objective. The aim of the present investigations was to evaluate aerobic capacity of intellectually disabled adults and determine its potential relationships with the degree of intellectual disability, somatic parameters, age and gender. Materials and method. The study group consisted of 85 intellectually disabled adults aged 20 to 40 years. The investigations were based on direct observation of the participants. The following somatic parameters were measured: body height and weight, waist and hip circumference, body fat percentage, body mass index and waist-to-hip ratio. Physical fitness was evaluated based on PWC170; VO2max was also calculated. Qualitative assessment of physical fitness level was carried out using Astrand’s classification (with respect to age and gender). Results. 30% of women and 46.3% of men had very low level of aerobic capacity. Absolute values of PWC170 and VO2max were significantly higher in men. However, relative values expressed in millilitres of oxygen per kilogram of body weight did not reveal statistically significant inter-gender differences. Age and degree of intellectual disability did not significantly influence the level of physical fitness. Multiple regression analysis to estimate VO2max/kg revealed a negative correlation with %FAT and WHR. Conclusions. 1. A large sample of the study population (30% female, 46.3% male) showed very low levels of aerobic capacity. 2. Our investigations did not demonstrate a relationship between physical fitness and age or the degree of intellectual disability. Gender turned out to be a differentiating factor but only for the absolute PWC170 and VO2max. 3. The level of physical fitness was significantly related to somatic parameters including body mass, waist and hips circumference, percentage of body fat, BMI and WHR.

Objectives To cross-validate the existing peak rate of oxygen consumption (VO₂peak) prediction equations in Dutch law enforcement officers and to determine whether these prediction equations can be used to predict VO₂ₚₑₐₖ for groups and in a single individual. A further objective was to report normative absolute and relative VO₂ₚₑₐₖ values of a sample of law enforcement officers in the Netherlands. Material and Methods The peak rate of oxygen consumption (ml×kg⁻¹×min⁻¹) was measured using a maximal incremental bicycle test in 1530 subjects, including 1068 male and 461 female police officers. Validity of the prediction equations for groups was assessed by comparing predicted VO₂ₚₑₐₖ with measured VO₂ₚₑₐₖ using paired t-tests. For individual differences limits of agreement (LoA) were calculated. Equations were considered valid for individuals when the difference between measured and predicted VO₂ₚₑₐₖ did not exceed ±1 metabolic equivalent (MET) in 95% of individuals. Results None of the equations met the validity criterion of 95% of individuals having ±1 MET difference or less than the measured value. Limits of agreement (LoAs) were large in all predictions. At the individual level, none of the equations were valid predictors of VO₂ₚₑₐₖ (ml×kg⁻¹×min⁻¹). Normative values for Dutch law enforcement officers were presented. Conclusions Substantial differences between measured and predicted VO₂ₚₑₐₖ (ml×kg⁻¹×min⁻¹) were found. Most tested equations were invalid predictors of VO₂ₚₑₐₖ at group level and all were invalid at individual levels.

Opis:
Strength training in adolescents is one of the pending subjects of Physical Education. Habitually, improvements in physical condition are solely and exclusively related to training in aerobic resistance. The objective of this study was to assess the effects of the incorporation of Crossfit along with aerobic games on aerobic capacity over a period of 8 weeks in a group of teens during their physical education sessions at the school. The study examined 82 subjects between 16-18 years of age, who were high school students. 40 women and 42 men were distributed into two groups, experimental and control. The results indicate that the effect on aerobic capacity measured through the course navette test is significantly positive through the inclusion of crossfit methodology along with aerobic games in physical education sessions.

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.

The world’s population is aging. Aquatic exercises can improve the physical function in humans and raise the quality of their lives in middle and older age. The study aimed to determine the effect of aqua aerobics on the selected somatic, physiological and aerobic capacity parameters in postmenopausal women. 11 purposively selected women that were confirmed overweight or obese by 20% and had Body Mass Index of 30±5 (the first stage of obesity) took part in aqua aerobics classes three times a week for 14 weeks. Their mean age was 56.18±3.19 years and mean height was 166.5±7.41 cm. The value of LBM and muscle mass (p=0.04 in both cases) were statistically significantly higher at study end compared with their baseline values, likewise haemoglobin concentration (p=0.001), haematocrit (p=0.03) and blood cell count (p=0.01), whereas BMI (p=0.02) and percentage body fat (p=0.04) were significantly lower. The lactate analysis revealed significant changes in LAmax (p=0.04), LAres9' (p=0.02), DeltaLAmax-LAsp (p=0.02) and DeltaLAres9’-LAres3’ (p=0,0004). After 14 weeks of aqua aerobic workout, significant changes were noted in the selected somatic, morphological and aerobic capacity parameters in postmenopausal women, but the differences between the lipid profiles were insignificant.

Opis:
In artistic gymnastic alteration of all component of coordination capacities may related to fatigue. So the resistance to fatigue is a specific endurance component, which has direct relation to the techniques of gymnastic exercises. We supposed that changes of motor actions precise in the process of fatigue development during training sessions might presumably have a negative impact on the quality of performing complex gymnastic elements and combinations and set the goal to determine the significance level of aerobic capacity for special endurance. Twelve young skilled gymnasts aged 15-18 years measured the maximum oxygen consumption (VO2 max). During the training sessions specially designed tests of specific endurance were carried out, heart rate (HR) was measured and the quality of the presentation of the combinations was evaluated (by the sum of the judges' ratings of all the elements). The interrelation between VO2 max, HR in progress of gymnastic combinations and the quality of their performance were analyzed. Results showed that a higher aerobic capacity contributes to a relatively lower HR when performing intense gymnastic combinations and a slower development. Iof “coordination fatigue” t may be of special importance for young athletes at the stage of advanced specialization when a great volume of complex combinations is learned and thus, high volume of training loads is performed. According to obtained data use of the proposed endurance tests is of great importance for control of maintenance of aerobic capacities by young athletes. Account of the factors of “coordination fatigue” development, related to aerobic capacities, may be of special importance for young gymnasts at the stage of advanced specialization when a great volume of complex combinations is learned and thus, high volume of training loads is performed.

Introduction. Research results indicate that a low level of physical fitness is associated with a high percentage of fat in the body and low levels of physical activity. The aim of this work was to assess the relationships between selected morphological indicators, and the level of aerobic capacity in adolescents attending the schools with team sports. Material and methods. The studies covered students participating in sports in middle school and high school; the study group included 90 boys aged 13-19 years. Body height and weight were measured as well as waist and hip circumference. Body weight components were assessed by using a Tanita Body Composition Analyzer. A Fitnessgram® test battery was used to assess physical fitness. Results. Research results indicates systematic increase of somatic characteristics such as weight, body height and waist and hips circuits with age. Taking into account the results obtained with the PACER test indicate a very good aerobic capacity of tested boys. Conclusions. Age is a factor that improves motor fitness of physically active adolescents. There is no linear relationship between BMI and fitness among the boys who regularly train team sports, but both lower and higher BMI values seem to be connected with lower physical fitness

Opis:
The purpose of this paper was to confront some selected physiological parameters that describe aerobic capacity with young swimmers’ sports achievements. For the study, some athletes with the average age of 14.67, who train swimming at the SMS Szczecin Club, were selected. A progressive test of their oxygen power was performed in order to determine their aerobic capacity, with the means of the European Ranking (LEN). Each swimmer’s sports level was presented in points [pts.]. The swimmers’ characteristics were presented as divided into three groups: (S) – short-distance specialization, (M) – medium-distance specialization and (L) – long-distance specialization. In group (S), maximum oxygen consumption – VO2max [l/min] achieved the levels of 3.95 [l/min] (male swimmers) and 2,77 [l/min] (female swimmers); in group (M) – 4.12 [l/min] and 2.97 [l/min], respectively; and in group (L) – 4.14 [l/min] and 3.338 [l/min]. Among male swimmers, level of VO2 max [ml/kg/min] equaled 58.96 – group (S), 59.72 – group (M) and 62.10 – group (L); while among female swimmers it reached 48.67 (S), 49.36 (M) and 54.60 (L), respectively. The recorded values of VO2 max [ml/kg/min] qualify the young swimmers to the group of people with a very high physical capacity. Our selection of Szczecin’s athletes to individual groups proved to be correct. The considerations presented in the paper bring one’s attention to the substantive quality of the intake and selection of swimmers. In the selection, it is necessary to take such physiologic rates as VO2 max or VO2/HR into consideration.

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.

The aim of the research carried out was to establish the direction, and scope of the changes in internal, and external load indicator values in cyclists, men, and women, in high-altitude hypoxia conditions. The participants of the study were mountain bike cyclists, members of Russian and Polish Nationals Teams (women n=11, men n=9). They have done the graded incremental exercise test at the altitude of 170 m (Lonato del Garda, Italy) and 2250 m (Livignio-Trepale Italy). In the course of effort VO2, VE, VCO2 was measured by means of K4b2 analyser (Cosmed Italy). Effort intensity was determined at ventilators thresholds VT1 (AT), and VT2. Internal and external load indicators undergo changes during physical effort in cyclists under the influence of high altitude hypoxia. In groups of men and women, the changes in indicator values reach VE: 9% and 12%, HR: 0,5% and 15, O2HR: 7% and 15%, VO2: 14% and 20% respectively, as well as a decrease in 5 and 4% of the generated power, respectively. A decrease in the generated power by 5%, higher ventilation, amounting to 10%, a higher VO2max, amounting to 17% in hypoxic conditions, in comparison with the conditions similar to those at sea level, show that it is necessary to modify training loads.

Introduction. Studies investigating the determinants of physical endurance were initiated nearly 30 years ago. The research was inspired by the curiosity to find out about the nature of talent for sport and why some athletes are better than others, despite the same or even greater effort in training routine, diet and the supplementation. An attempt was therefore made to determine the genotype of a perfect athlete, but conducted research showed that it is a very difficult task. Although 140 genes were proposed to affect of ideal sportsman fitness, scientists are still far from formulating answers about the nature of physical abilities and genotype. Aim. Our main goal was to review the literature about the selected genes and polymorphisms which are most often investigated in the context in relation to injury in sports. Materials and methods. Analysis of literature from US National Library of Medicine, National Institutes of Health, PubMED, Google Scholar. Results. We review the selected genes and polymorphisms which are most often investigated in the context in relation to injury in sports, we also present the function of genetic variants prevalent in athletes which are able to achieve better physiological adaptation during the training. Conclusions. There are probably more than 140 genes involved in physical performance. Changes in even one nucleotide within the gene (SNP) can improve the body’s adaptation to better physical performance and the frequency of injury to athletes.

Objectives: The purpose of this study was to compare values of aerobic performance in the 1-mile run test (1-MRT) using different formulae. Material and Methods: Aerobic capacities of 351 male volunteers working for the Turkish National Police within the age range of 20-23 years were evaluated by the 1-MRT and the 20-metre shuttle run (20-MST). $\text{VO}_\text{2max}$ values were estimated by the prediction equations developed by George et al. (1993), Cureton et al. (1995) and Kline et al. (1987) for the 1-MRT and by Leger and Lambert (1982) for the 20-MST. Results: The difference between the results of the different formulae was significant (p = 0.000). The correlation coefficient between the estimated $\text{VO}_\text{2max}$ using Cureton's equation, George's equation, Kline's equation and the 20-MST were 0.691 (p < 0.001), 0.486 (p < 0.001) and 0.608 (p < 0.001), respectively. The highest correlation coefficient was between the $\text{VO}_\text{2max}$ estimated by the 20-MST and Cureton's equation. Similarly, the highest correlation coefficient (r = -0.779) was between the 1-mile run time and the $\text{VO}_\text{2max}$ estimated by Cureton's equation. Conclusions: When analysing more vigorous exercise than sub-maximal exercise, we suggest that Cureton's equation be used to predict the $\text{VO}_\text{2max}$ from 1-mile run/walk performance in large numbers of healthy individuals with high $\text{VO}_\text{2max}$. This research compares the use of 3 different formulae to estimate $\text{VO}_\text{2max}$ from 1-mile run/walk performance in male law enforcement officers aged 20-23 years for the first time and reports the most accurate formula to use when evaluating aerobic capacities of large numbers of healthy individuals.

Opis:
Thirty healthy trammers were examined in underground haulage mines during their normal activity. Physiological strain in terms of heart rate (HR) varied between 101.6 and 104.7 beats/min with mean net cardiac cost of 33.06 and 34.06 beats/min for younger and older groups respectively. The average relative cardiac cost was lower for younger subjects than for older ones. Oxygen consumption (VO2) was measured with an Oxylog-II machine (UK); subsequently values were estimated. Maximum aerobic capacity was estimated with an indirect method following a standard step test protocol. The responses revealed that the average VO2 during the activity was 0.75 and 0.8 L/min, which corresponded to energy expenditure (EE) of 3.8 and 3.97 Kcal/min for younger and older subjects respectively. The workload in terms of HR and EE was moderate, whereas the aerobic strain experienced by aged workers was above the acceptable level.

Objectives: The aim of this study was to compare the influence of creatine monohydrate and creatine malate supplementation on aerobic and anaerobic capacity in semi-professional soccer players during preparation period. Methods: 15 adult soccer players from polish second league club took part in the study. Participants were divided into two groups (Group 1: supplemented their diet with creatine monohydrate; group 2: used creatine malate). Before and after five-week preparations the aerobic (PWC 170 test) and anaerobic (Wingate test) capacity of the players were measured. Findings: Significant increase in PWC 170 indicator, maximal oxygen uptake, and total work capacity in Wingate test were noted in the group that consumed creatine monohydrate. Moreover, two-way ANOVA results showed significant effect for time in above mentioned variables. Conclusions: Creatine monohydrate supplementation may efficiently support aerobic and anaerobic capacity development in semi-professional soccer players. Five-week creatine malate supplementation provides no significant changes in aerobic and anaerobic capacity.

The aim of the work was to assess the intensity of purine nucleotide degradation during maximum physical exercise. 5 elite female boxers were the subject of the study. Each of them underwent two exercise stress tests in order to evaluate the level of V̊O2peak and the level of anaerobic capacity during a Wingate test. The study involved collecting capillary and venous blood samples at rest and after the exercise test to determine the Acid-Base Balance (ABB), concentration of lactic acid (LA) and purine metabolism nucleotides. The average value of V̊O2peak was 40.92 (SD = 4.087) ml/kg/min, the average anaerobic capacity Ppeak was 7.57 (SD = 0.380) Watt/kg. The workload resulted in significant changes in the level of ABB and LA after both of the exercise stress tests (p < 0.001). Concentrations of hypoxanthine (Hx), xanthine (X) and uric acid (UA) in the blood increased significantly after the Wingate test (p < 0.05). The level of plasma purine nucleotides at rest and after standard exercise may be a useful tool for monitoring the adaptation of energetic processes in different training phases and support the overload diagnosis.

Opis:
A long-term sports training induces morphological and functional changes in the cardiovascular system, with the activation of angiogenesis being one of the most significant ones. Aim: The aim of the study was to assess the impact of an 8-month sports training on the serum levels of vascular endothelial growth factor and the physical performance in young athletes. Material and methods: A total of 28 sports middle school students (athletics faculty) aged 13 years, including 14 boys and 14 girls, were included in the study. All participants underwent clinical assessment at each stage of the study. Electrocardiographic and echocardiographic examinations were performed. Furthermore, the levels of vascular endothelial growth factor were measured and a cardiac stress test was performed, the outcome of which was used to calculate the physical working capacity (PWC170). Results: There was a statistically significant decrease (274.3 ± 195.7 vs. 193.8 ± 153.8 ng/ml, p < 0.001) in the serum levels of vascular endothelial growth factor during the 8-month sports training. The levels were significantly lower in male athletes both at baseline (196.2 ± 157.3 vs. 352.4 ± 204.0 ng/ml, p = 0.02), and at the end of the observation period (139.6 ± 110.9 vs. 247.9 ± 174.6 ng/ml, p = 0.003). In the same period, the average PWC170 value increased throughout the study group (108.6 ± 28.1 vs. 119.0 ± 34.1 W, p = 0.02), and sex-related statistically significant changes occurred only on the male group of athletes. No statistically significant correlations were found between the relative changes in the levels of vascular endothelial growth factor and the PWC170 index (Spearman’s rank correlation coefficient – Rs 0.158, p > 0.05). Conclusions: Long-term sports training results in a decrease in the levels of vascular endothelial growth factor. At the same time, physical efficiency improvement is observed, which may suggest the involvement of adaptive, exerciseinduced angiogenesis in the skeletal muscles. However, the observed changes show distinct differences depending on the sex.
Długotrwały trening sportowy prowadzi do morfologicznych i czynnościowych zmian w układzie sercowo-naczyniowym, wśród których ważne miejsce zajmuje aktywacja procesów angiogenezy. Cel pracy: Celem pracy była ocena wpływu 8-miesięcznego treningu sportowego na stężenie naczyniowo-śródbłonkowego czynnika wzrostu w surowicy oraz wydolność fizyczną u młodych lekkoatletów. Materiał i metody: Badaniem objęto 28 uczniów gimnazjum sportowego o profilu lekkoatletycznym w wieku 13 lat, w tym 14 chłopców i 14 dziewcząt. Na każdym etapie badania wszyscy uczestnicy zostali poddani ocenie klinicznej. Wykonano u nich badania elektrokardiograficzne oraz echokardiograficzne. Oznaczono także stężenie naczyniowo-śródbłonkowego czynnika wzrostu oraz przeprowadzono próbę wysiłkową, której wynik posłużył do wyliczenia wskaźnika wydolności tlenowej PWC170. Wyniki badań: Podczas 8-miesięcznego treningu stężenie naczyniowo- -śródbłonkowego czynnika wzrostu w surowicy zmniejszyło się istotnie statystycznie (274,3 ± 195,7 vs 193,8 ± 153,8 ng/ml, p < 0,001). Jego stężenie było też istotnie niższe w grupie sportowców płci męskiej, zarówno na początku (196,2 ± 157,3 vs 352,4 ± 204,0 ng/ml, p = 0,02), jak i na końcu okresu obserwacji (139,6 ± 110,9 vs 247,9 ± 174,6 ng/ml, p = 0,003). W tym samym okresie średnia wartość wskaźnika PWC170 zwiększyła się w całej badanej grupie (108,6 ± 28,1 vs 119,0 ± 34,1 W, p = 0,02), a w odniesieniu do płci zmiany istotne statystycznie wystąpiły tylko u sportowców płci męskiej. Nie stwierdzono istotnych statystycznie korelacji pomiędzy względnymi zmianami stężenia naczyniowo-śródbłonkowego czynnika wzrostu i wartości wskaźnika PWC170 (współczynnik korelacji rang Spearmana – Rs 0,158, p > 0,05). Wnioski: Podczas długotrwałego treningu sportowego dochodzi do obniżenia stężenia naczyniowo-śródbłonkowego czynnika wzrostu. Jednocześnie obserwowana poprawa wydolności fizycznej może sugerować, że odbywa się to przy udziale adaptacyjnej, indukowanej wysiłkiem fizycznym angiogenezy w mięśniach szkieletowych. Zmiany te wykazują jednak wyraźne różnice zależne od płci.

Opis:
Głównym celem opracowania była odpowiedź na pytanie, jaki jest wpływ regularnych ćwiczeń aerobowych na poziom rozwoju zdolności motorycznych 20-letnich kobiet. Badaniami objęto 12 dziewcząt, studentek Uniwersytetu Jagiellońskiego, uczęszczających regularnie (2 razy w tygodniu) na zajęcia aerobowe zamiast regularnych zajęć wychowania fizycznego. Zajęcia były obowiązkowe i trwały 4 miesiące. Przed podjęciem przez kobiety zajęć aerobowych oraz po ich zakończeniu wykonano testy pośrednie określające poziom poszczególnych zdolności motorycznych, tj. szybkości, siły, wytrzymałości i koordynacji. Uzyskane wyniki poddano podstawowej analizie statystycznej. Na ich podstawie stwierdzono, że zajęcia aerobowe nie wpłynęły na średnią masę ciała badanych dziewcząt. Stąd wniosek, że regularne zajęcia aerobowe mają raczej wpływ na utrzymanie stałej masy ciała niż jej redukcję, co jest zgodne z danymi z literatury. Nie stwierdzono jednoznacznych zmian w poprawie wytrzymałości (różnokierunkowe zmiany VO2max). Wyniki te wskazują na różną odpowiedź poszczególnych uczestniczek zajęć aerobowych, zależną z pewnością od wyjściowego poziomu wytrenowania. Stąd konieczna wydaje się wstępna selekcja niejednorodnych pod względem sprawności grup, która umożliwi odpowiedni dobór ćwiczeń w stosunku do wyjściowej wydolności organizmu. U wszystkich badanych kobiet zanotowano poprawę wyników w próbach badających takie zdolności motoryczne, jak siła czy szybkość. Wskazuje to na przewagę komponentu siłowo-szybkościowego w prowadzonych zajęciach aerobowych.
The aim of this study is to present the results of research, i.e. to answer the question: what is the influence of aerobics exercises to young women's motor capabilities. Some tests has been done to evaluate the level of young women's physical fitness (the main indicator-mark was the VO2max). Twelve students were examined. They have declared the low level of their physical activity. They have participated in cycle of aerobics exercises, which lasted for16 weeks. The aim of this research was to confirm the thesis that aerobics exercises have a positive influence on young women's physiological and morphological traits. Material and methods: During the experiment 12 students were examined. The cycle of aerobics exercises lasted for 4 months. One, separate activity (60 minutes) took place once a week, on Friday's afternoon. The results were put to the statistical analysis and the process of normalization, which showed the direction of parameter's changing. Results and conclusions: The reduction of weight was the motivation to attend to this cycle of aerobics exercises. In spite of that a decrease in this parameter was inconsiderable. The experiment showed that VO2max parameter increased in those women, who had a lower initial level of this mark. After 4 months of regular aerobics exercises ressearchers noticed that results of those women, who had higher initial VO2max changed for the worse. Regular aerobics activities helped all the participants to keep the constant weight, which was consistent with another author's publication. The results pointed out the necessity of initial selection of women in such a heterogeneous group. The main mark of this selection seemed to be VO2max. This should enable the proper selection of exercises and make the practice more effective. The resserchers noticed a significant improvement in such motor capabilities like: strength and speed (superiority in anaerobic components).
