Background: The aim of the study was to designate changes in the expression of HSPA1A, HSPB1 and LDHb in elite rowers after completing a test “till exhaustion” on a rowing ergometer. Finally, we searched for the answer whether there are significant correlations between the expression of the genes and anaerobic threshold (AnT) or the maximal oxygen uptake (VO2max). Material/Methods: The research was conducted on the sample of 9 Polish lightweight male rowers (23.7 ±3.77 yrs, 72.7 ±1.76 kg, 183.6 ±4.58 cm). To determine AnT and VO2max, the subjects performed the test “till exhaustion” with an increasing load on a rowing ergometer. Directly before and after the test, blood samples were collected from the ulnar vein in order to isolate genetic material. RNA was extracted from white cells of venous blood by the chemical method. 2 µg RNA for the reverse transcription was used and the expression of HSPA1A, HSPB1 and LDHb was determined by Real time PCR reaction. To assess the intensity of expression, the ∆∆Ct method was used. Results: The study showed an increased expression of HSPA1A and HSPB1 and a decreased one of LDHb. Moreover, post-training changes of the genes activity in white blood cells occurred immediately and could be determined directly after the termination of exertion. Conclusions: No significant correlations between the expression of the genes and anaerobic threshold (AnT), maximal oxygen uptake (VO2max) were stated.

Introduction. Physical training is considered an effective means of preventing and treating diseases of affluence such as T2DM. The key benefits of this therapy include improvements in physical performance and in metabolic processes. Aim of Study. The aim of this study was to investigate the impact of a 12-week long supervised combined strength and endurance training program on physical performance of T2DM patients with various complications. Material and Methods. The study was carried out on patients stratified into Groups (levels) 2 and 3 according to the criteria from the 2007 Danish program “Forløbsprogram for Type 2 Diabetes” (see Table 1). A total of 83 patients (29 women, 54 men) participated in the study, aged 65.5 ± 10.62 years. The subjects were offered 60 minutes of supervised group exercise, twice a week for 12 weeks. Each session consisted of a 5-min warm-up, 35-min strength exercise, and 10-min aerobic bicycling, with a load between 12 and 15 on the Borg Scale. Physical performance was measured using a 30-second sit-to-stand test (STS) and 6-minute-walk test (6MWT). Results. A significant improvement in STS was noted in Group 2 (mean = 1.6 ± 2.39; 95% CI 0.92-2.3) and in Group 3 (mean = 1.46 ± 2.14; 95% CI 0.74-2.17). Statistically significant (p <0.0001) 6MWT results were obtained in Group 2 (mean = 46.7 ± 54.08; (95% CI 30-63) and in Group 3 (mean = 46.2 ± 79.51; 95% CI 12-79). Participation in training sessions played a paramount role in improving the effectiveness of combined strength and endurance training. Conclusion. Participation in a 12-week exercise program increased physical performance in patients with type 2 diabetes, regardless of their complication status.

In recent years, EEG-neurofeedback training (EEG-NFB) has been increasingly used to optimize various brain functions. Better performance in various activities was also reported after relaxation trainings, another popular method in therapeutic practice. Both these methods are used as a part of professional coaching in sports training centers. In the present study, we aimed to evaluate the impact of such holistic training on physiological (EEG) and behavioral measures on semi-professional athletes. EEG-NFB paradigm was intended for amplification of the amplitudes of SMR (12–15 Hz) and beta1 (13–20 Hz) bands and simultaneous reduction of the amplitude of theta (4–7.5 Hz) and beta2 (20–30 Hz). Participation in NFB sessions was accompanied with self-administration of relaxing, audio-visual stimulation after each daily athletic training session. The training program resulted in the increase of alpha and beta1 power of trained participants when assessed in rest with eyes-closed. In eyes – open state, participants of the trained group maintained the same level in all frequency bands, in opposite to the control subjects, whose power decreased in the second measurement in beta1 band when compared to the first one. The trained group exhibited greater reduction of reaction times in a test of visual attention than the control group and showed improvement in several performance measures of Kraepelin’s work-curve, used to evaluate speed, effectiveness and work accuracy. Together, these results present initial support for the use of holistic, neurophysiological training in sports workout.

Effect of training on the heart rate in mares. The purpose of this paper was to determine the effect of training on the heart rate in mares and analyse the adaptation of examined specimens to training loads. The tests were carried out on the basis of measurements of the post-effort resting heart rate and restitution time at various training stages in the Training Centre in Bielice. The measurements were taken with an electric heart rate monitorin 56 mares. The resting heart rate in mares was higher than in the final training stage. The heart rate restitution was quicker at the end of the training period. A significant influence of the length of training of mares selected for tests on the way they had reacted to the same load was observed. Horses with a longer preparation period had better efficiency parameters, both at rest and after training. An influence of the level of preparation of mares on their results of the final test in the training centre was also demonstrated – the average grade of mares following an extended preparation period was higher by 2 points.

The main purpose of this study was to determine the influence of different types of surfaces on the sprint test results. 33 male football players from two age categories – U15 and U18 – performed sprint tests (7 distances between 5 and 30 m) and a 150 m shuttle run test on three types of surfaces: natural grass [n], a synthetic surface [s] and a rubber surface [r]. The longer distance a player covers, the more likely it is that the importance of the type of running surface will be noticed. The rubber surface diminishes the negative effects of changeable factors on the reliability of the tests and therefore, in our opinion, is recommended for control tests and especially for longitudinal tests. Comparing the results of running speed tests performed on different surfaces and especially in different weather conditions is unjustified.

Celem badań była ocena: prawidłowości komponowania racji pokarmowych, stanu odżywienia na podstawie wybranych parametrów antropometrycznych oraz wydolności fizycznej grupy studentów poznańskich uczelni. Badania przeprowadzono z udziałem 62 studentów w wieku od 19 do 26 lat. Średnia masa ciała mężczyzn wyniosła 79,0 ± 15,0 kg, a wskaźnik BMI kształtował się na poziomie 24,4 ± 4,7 kg/m2. Wszyscy badani deklarowali umiarkowaną aktywność fizyczną oraz dobry ogólny stan zdrowia. Sposób żywienia studentów określono metodą 24-godzinnego wywiadu żywieniowego, przeprowadzonego trzykrotnie. Ocena stanu odżywienia obejmowała pomiary antropometryczne (BMI, WHR, grubość fałdów tłuszczowo-skórnych) oraz analizę składu ciała (tkankę tłuszczową – FM [%] i beztłuszczową masę ciała – FFM [%]) przeprowadzoną metodą impedancji bioelektrycznej, bioanalizatorem typu BIA 101S, AKERN-RJL. Wydolność fizyczną mężczyzn określono za pomocą testu Fitness, z wykorzystaniem miernika pracy serca Polar Sport Tester S-610. Na podstawie analizy rozkładu poziomów wskaźnika BMI, przeprowadzonej zgodnie z klasyfikacją podaną przez WHO, stwierdzono, że blisko 1/3 młodych mężczyzn charakteryzowała nadwaga lub otyłość. Zawartość tłuszczu w ciele (FM) studentów kształtowała się na poziomie 19,7 ± 8,7%, natomiast beztłuszczowa masa ciała (FFM) wyniosła 60,1 ± 7,0 kg. Ocena wydolności fizycznej z wykorzystaniem testu Fitness (FT) dowiodła, że mężczyźni prezentowali przeciętny poziom wydolności fizycznej (FT: 43,0 ± 8,7), który jednocześnie korelował z zawartością FFM w ciele (r = 0,58, p < 0,001). Dzienne racje pokarmowe studentów były niezbilansowane w odniesieniu do podaży tłuszczu, błonnika pokarmowego, cholesterolu, białka oraz proporcji Ca : P. Podaż tłuszczu w diecie korelowała ze wskaźnikami: BMI (r = 0,64, p < 0,001), WHR (r = 0,56, p < 0,001), udziałem tłuszczu (FM) w ciele (r = 0,60, p < 0,001) oraz średnią grubością fałdów tłuszczowo-skórnych (r = 0,52, p < 0,05).
