Desempenho muscular isocinético dos ombros em atletas de rúgbi

*** Isokinetic muscle performance of shoulders in rugby athletes ***AIMS: To verify the existence of shoulder external and internal rotator muscle asymmetries in male amateur rugby athletes.METHODS: Isokinetic evaluations of male amateur rugby athletes were accessed from the database of the Institute for Sports Medicine and Applied Sciences in Human Movement of Universidade de Caxias do Sul (IME-UCS). Shoulders evaluated were included in the study, whereas those cases without a free and informed consent form signed prior to the test were excluded. The isokinetic dynamometer was used in a concentric-concentric mode for the shoulder external and internal rotators at angular velocities of 60°/s and 180°/s. The peak torque and the external to internal rotator ratio were analyzed. Student’s t test and a significance level of <0.05 were used to verify the existence of asymmetries between the two sides of the same individual.RESULTS: Data from 12 male athletes were analyzed. Regarding the peak torque at the angular velocity of 60º/s, the mean muscle strength values of the dominant limb were significantly higher when compared to non-dominant limb: external rotators, 43.35±4.72 Nm for the dominant limb vs 38.92±4.22 Nm for the non-dominant limb (p=0.0012); internal rotators, 65.58±11.88 Nm for the dominant limb vs 61.69±11.98 Nm for the non-dominant limb (p=0.0021). At 180º/s, the mean values of the non-dominant limb tended to be lower when compared to the dominant limb, without statistical significance. Regarding the mean values of the external to internal rotator ratio, no significant differences were found at any of the angular velocities analyzed.CONCLUSIONS: Amateur rugby athletes showed lower muscle strength of the non-dominant limb when compared to the dominant limb in the peak torque measurements. This difference was not found in other studies with rugby athletes, and we believe that this result is justified by the lack of more frequent and adequate training of these amateur athletes.

Introduction: Cellulitis remains a very serious disease even today. Mortality, which varied between 10–40%, has been reduced owing to the standard securing of airway patency and use of an appropriate surgical treatment approach. Materials and methods: A total of 195 patients were hospitalised for cellulitis at the University Hospital in Hradec Králové during 2007–2011. The following parameters were evaluated: age, gender, dependence of incidence of the disease on the season of the year, frequency of attacks of the particular areas and their clinical characteristics, aetiology of the inflammation, types of patient complaints, prevalence of current systemic diseases, results of microbiological and selected laboratory analyses, socio-economic status of the patients, and duration of patient stay at the hospital. Statistical analysis was performed by using Pearson’s correlation coefficient, the statistical significance level was p < 0.05. Results: The mean age of the patients was 39.8 years. The group of 195 patients included 108 (55%) males and 87 (45%) females. The mean time between the first symptoms of the disease and admission to the Department was 5 days. From among the 195 patients, 116 (59.5%) were working persons, 79 (40.5%) were non-working (children, students, unemployed persons, women on maternity leave, retired people). The odontogenic origin of the disease was verified in 173 (88.7%) patients. In total, 65 (33.3%) patients had no coinciding complicating systemic disease, 22 (11.3%) patients had diabetes mellitus. The most frequent symptom of cellulitis was painful swelling, found in 194 (99.5%) patients, followed by jaw contracture, found in 153 (78.5%) patients. Conclusion: The results are largely very similar to those of previous studies performed in other countries, except that we found no correlation between the prevalence of cellulitis and the socio-economic status, nor have we confirmed Klebsiella pneumoniae sp. as the cause of cellulitis in patients with diabetes mellitus.

Abstract Systematic assessment of muscle strength of the lower extremities throughout the annual training cycle in athletes is crucial from a performance perspective for the optimization of the training process, as well as a health perspective with regard to injury prevention. The main aim of the present study was to determine isokinetic muscle strength of the knee flexors and extensors in female handball players at the beginning of a preparatory period and to assess whether there were any differences between players of different performance levels. The performance level was expressed by means of membership of the Women’s Junior National Handball Team (JNT, n=8) or the Women’s National Handball Team (NT, n=9). The isokinetic peak torque during concentric and eccentric single-joint knee flexion and extension was measured at angular velocities of 60, 180, 240°/s (concentric) and 60°/s (eccentric). The Mann- Whitney test showed no significant differences in the peak torques or ipsilateral ratios between the two groups. The bilateral force deficit (BFD) for concentric extension at 240°/s was significantly higher in the JNT compared with the NT (p=0.04; d=1.02). However, the results of individual evaluation show that the BFD was more frequent in the NT in most measurements. A high BFD was evident in the eccentric mode in both groups highlighting a need for particular strengthening. With regard to low strength ratios a prevention programme should be suggested for both observed groups of professional female handball players to reduce the risk of injury.

In this paper, trend detection of wave parameters such as significant wave height, energy period, and wave power along the Italian seas was carried out. To this purpose, wave time series in the period 1979–2018 taken from the global atmospheric reanalysis ERA-Interim by European Center for Medium-Range Weather Forecasts (ECMWF) were considered. Choosing a significance level equal to 90%, the use of the Mann–Kendall test allowed estimating ongoing trends on the mean values evaluated at yearly and seasonal scale. Furthermore, the assessment of the magnitude of the increase/decrease of the wave parameters was performed through the Theil–Sen estimator. The obtained results underlined that the mean values of the considered wave parameters were characterized by a high occurrence of positive trends in the different Italian seas. The findings of this study could have implications for studies of coastal flooding, shoreline variations, and port operations, and for the assessment of the performances of Wave Energy Converters.

The infiltration capacities (IC) of three different sands were measured repeatedly in a laboratory using a double-ring infiltrometer (DRI) and the Cornell Sprinkle Infiltrometer (CSI). The study assessed (1) the level of agreement between the infiltrometers, and (2) the reproducibility of values produced by each infiltrometer. The results were inconclusive regarding the agreement of IC measurements: the percentage difference in the mean IC was small for one sand (4%), but larger for the other two (32 and 48%), with the CSI yielding higher values than the DRI in both of these cases. For these latter two sands, the measurements were different at a statistical significance level of 0.01 and 0.05, respectively. Likewise, the results were inconclusive regarding the reproducibility of each instrument. The CSI showed much better reproducibility than the DRI for one sand (relative standard deviations of 7% and 26%, respectively), but slightly worse for the other two (23% and 18%, and 22% and 19%), respectively.

Tomato (Lycopersicon esculentum Mill.) is major fruity vegetables grown in Ethiopia next to hot pepper. Although crops grown in the country its production and productivity is very low compared to the world average. Among the reasons for low its production and productivity, shortage of improved tomato varieties is the major one. This experiment was done with the aim of evaluating tomato varieties and select high yielding cultivars. An experiment was conducted in bonga district Gambella region 2011/12 dry season under irrigated condition. Seven tomato varieties namely ARP Tomato D2, Fetan, Melkasalsa, Chali, Bishola, Gelila and Roma-VF(as local check) and were tested in randomized complete block design with 3 replications. The mean values of all parameters were subjected to two way analysis of variance using the Proc GLM procedure of SAS 9.3. Then statistical significance of the mean of each parameter was determined using F-test and Duncan multiple range test procedure was used to compare differences between treatment means at 5% probability level. The analysis of variance showed statistically significant differences (p< 0.05) among varieties in all growth and yield parameters except days to 50% flowering. Among the tested tomato cultivars, Melkasalsa produced the largest fruit. The highest fruit yield was recorded by Melkasalsa followed by Bishola. we can conclude Melkasalsa and Bishola variety were the most productive and gave larger fruit compared to others. Hence, these varieties can be used by tomato growers under irrigated condition around Bonga area.

Background: Eggshell which is primarily composed of more than 98% calcium carbonate crystal, serves as the physical protective and active barrier structure of egg content. Recently, antimicrobial properties of eggshell are fast becoming center of interest among stakeholders of poultry industry. However, few studies have focused on the rigidity factor of calcium components of eggshell as antimicrobial agent. Thus, this study was designed to determine the effect of decalcification on the ability of eggshell to inhibit common poultry and egg bacterial pathogens.Methods: Raw eggshell denoted as calcified eggshell (CES) and decalcified eggshell (DES) were extracted and made into fine powder. Standard protocol was used for preparations of CES and DES at concentrations of 10, 5, 2.5 and 1.25 mg/ml, and their antibacterial assays on selected bacterial pathogens (Bacillus subtilis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Salmonella Typhi) were performed by agar diffusion method. Gentamicin 80mg solution (CC1) and distilled water (CC2) served as controls. Data were analysed with SPSS version 20.0 and presented as mean±SD for descriptive statistics. Friedman's two-way test ANOVA was used to compare the differences in mean values between CES, DES, CC1 and CC2 at significance level of p<0.05.Results: The mean zone diameter of inhibition produced by DES (range 13–28mm) for the isolates was significantly higher (p<0.05) than that produced by CES (range 10-21mm). However, the mean zone diameter of inhibition produced by CC1 (gentamicin) (range 16-40mm) was higher than that produced by DES or CES (p<0.05). The concentrations of DES and CES have no significant antibacterial effect on B. subtilis and K. pneumoniae (p>0.05), but had inverse effect on P. aeruginosa. Overall, DES had a better inhibitory effect than CES against B. subtilis, K. pneumoniae and P. aeruginosa, but notably, neither DES nor CES had inhibitory effect on E. coli and S. Typhi.Conclusion: Poor antibacterial effect of CES may be attributed to the calcium-protein interactions within bacterial cell membrane, which hinders absorption or mobility mechanism of the antibacterial factor of the eggshell, but decalcification had significant impact on the antibacterial profile of the eggshell for some bacterial isolates. However, S. Typhi and E. coli were totally resistant to both DES and CES. Breed of eggs with minimal calcified eggshell to withstand transportation fragility, may enhance antibacterial index and shelf-life of table eggs.

The purpose of this study was to evaluate the inspiratory and expiratory muscle strength of individuals affected by stroke and to compare it with the predicted values in the literature considering their corresponding age. Respiratory muscle strength was evaluated in 22 elderly people who had sequels of stroke, four with right hemiparesis, 16 with left hemiparesis and two with bilateral, of ages ranging from 34 to 82 years. The collected data were submitted to statistical analysis using a Mann–Whitney test to evaluate if there was a significant difference in the average data collected when compared with a mean of the predicted data in the literature. Fourteen men and eight women were evaluated, who obtained mean values of 71.85 cmH2O and 57.75 cmH2O, respectively, for a maximal inspiratory pressure (MIP), and when compared to the predicted values for men and women, 105.41 cmH2O (p-value 0.0019) and 80.57 cmH2O (p-value 0.00464) were significantly lower. For a maximal expiratory pressure (MEP), the mean value obtained for men was 62.28 cmH2O and 49.5 cmH2O for women, whereas the predicted values in the literature were 114.79 cmH2O (p-value < 0.0001) and 78, 46 cmH2O (p-value 0.0059), respectively. In the statistical analysis, it was possible to notice that the studied population did not reach the predicted age indexes and that there was a significant difference between the median columns. In conclusion, there is a weakness in the respiratory muscles of hemiparetic men and women due to stroke.
