The practice of strength training (ST) promotes several benefits such as increased strength, endurance, muscle strength, hypertrophy, as well as changes in body composition. Concentric failure (CF)Several studies show that exercise until CF may be more efficient in promoting positive adaptations about hypertrophy and muscle strength, however, it is still unclear at which time of the exercise CF is achieved. The number of repetitions (NR) performed in each set may be influenced by fatigue caused by CF training. The objective was to analyze the response of the NR between sets as indicative of CF within a session of ST. The study included fourteen trained men (25.0 ± 3.5 years old) (5 ± 4 years) who performed three sets with 75% of 1(repetition maximum) (RM) until CF with fixed rest interval between sets. Statistical analysis: Data normality was tested according to the Shapiro-Wilk test. Subsequently the one-way ANOVA of repeated measures was used to compare the variance of the means between the moments and, when necessary, the post hoc test was used for multiple comparisons using Bonferroni correction. Percentage variations of decreasing NR between sets were found, being from the 1st vs. 2nd set (45,3 ± 14,6 %;), 2nd vs. 3rd set (41,4 ± 19,5%), and 1st vs. 3rd set (67,8 ± 15,1%). The NR can be used to identify if the exercise is being performed up to the CF, considering that the NR between sets decreases substantially due to acute metabolic changes.

The aim of this in vitro study was to investigate the degree of C=C double bond conversion of high-viscosity dimethacrylate- or ormocer-based bulk-fill composites as a function of measurement depth. Four bulk-fill composites (Tetric EvoCeram Bulk Fill, x-tra fil, SonicFill, and Bulk Ormocer) and the conventional nanohybrid composite Tetric EvoCeram were applied in standardized Class II cavities (n = 6 per group) and photoactivated for 20 s at 1350 mW/cm2. The degree of conversion of the composites was assessed using Fourier-transform infrared spectroscopy at seven measurement depths (0.15, 1, 2, 3, 4, 5, 6 mm). Data were analyzed using repeated measures ANOVA and one-way ANOVA with Bonferroni post-hoc tests (α = 0.05). The investigated bulk-fill composites showed at least 80% of their maximum degree of conversion (80% DCmax) up to a measuring depth of at least 4 mm. Tetric EvoCeram Bulk Fill and Bulk Ormocer achieved more than 80% DCmax up to a measuring depth of 5 mm, x-tra fil up to 6 mm. The conventional nanohybrid composite Tetric EvoCeram achieved more than 80% DCmax up to 3 mm. In contrast to the conventional composite, the investigated ormocer- and dimethacrylate-based bulk-fill composites can be photo-polymerized in thick layers of up to at least 4 mm with regard to their degree of C=C double bond conversion.

The present study aimed at investigating changes in behavior (shooting precision) and electrophysiological variables (absolute alpha power) during the motor learning of practical pistol shooting. The sample was composed of 23 healthy subjects, right-handed, male, between 18 and 20 years of age. The task consisted of four learning blocks. A One-way ANOVA with repeated measures and a post hoc analysis were employed to observe modifications on behavioral and electrophysiological measures (p<0.05). The results showed significative differences between blocks according to motor learning, and a significant improvement in shooting's accuracy from both blocks. It was observed a decrease in alpha power in all electrodes examined during task execution when compared with baseline and learning control blocks. The findings suggest that alpha power decreases as the function of the motor learning task when subjects are engaged in the motor execution.

OBJECTIVES: The present in vitro study was designed to compare the differences in the vertical misfit of implant-supported frameworks using three different forces for tightening the bridge locking screws: fastening by hand until first resistance, and using torque drivers with 10 and 20Ncm. METHODS: The investigation was conducted based on the results given by 9 six-unit nickel-chromium (2 abutments/ 4 pontics) screw-retained implant-supported frameworks. The structures were exposed to simulated porcelain firings. The marginal misfit measurements were made using a traveling measuring microscope at selected screw tightening forces: fastening by hand until first resistance, and using torque drivers with 10 and 20Ncm. The results were submitted to one-way ANOVA with repeated measures on one factor, and post hoc pairwise comparisons using Tukey test (5%). RESULTS: The mean marginal misfit of the frameworks, fastening the screws by hand until first resistance, was 41.56µm (SD±12.45µm). The use of torque driver devices caused a significant reduction in marginal opening (p<0.05). With the lowest torque available (10Ncm), the mean marginal discrepancy at the abutment-framework interface was reduced an average of 52% to a mean marginal opening of 19.71µm (SD±2.97µm). After the use of the 20Ncm torque driver, the mean marginal discrepancy of the frameworks was reduced an average of 69% to a mean marginal opening of 12.82µm (SD±4.0µm). Comparing the use of torque drivers with 10 and 20 Ncm torque, the means are not significantly different from one another. CONCLUSION: The seating force has an important effect on the vertical misfit measurements, once it may considerably narrow the vertical misfit gaps at the abutment-framework interface, thus leading to a misjudgment of the real marginal situation.

This study aims to evaluate the change in gait spatiotemporal parameters in subjects with Parkinson’s disease (PD) before and after Automated Mechanical Peripheral Stimulation (AMPS) treatment. Thirty-five subjects with PD and 35 healthy age-matched subjects took part in this study. A dedicated medical device (Gondola) was used to administer the AMPS. All patients with PD were treated in off levodopa phase and their gait performances were evaluated by an inertial measurement system before and after the intervention. The one-way ANOVA for repeated measures was performed to assess the differences between pre- and post-AMPS and the one-way ANOVA to assess the differences between PD patients and the control group. Spearman’s correlations assessed the associations between patients with PD clinical status (H&Y) and the percentage of improvement of the gait variables after AMPS (α<0.05for all tests). The PD group had an improvement of 14.85% in the stride length; 14.77% in the gait velocity; and 29.91% in the gait propulsion. The correlation results showed that the higher the H&Y classification, the higher the stride length percentage of improvement. The treatment based on AMPS intervention seems to induce a better performance in the gait pattern of PD patients, mainly in intermediate and advanced stages of the condition.

Carnitine deficiency is prevalent in patients undergoing hemodialysis, and it could result in lowered muscle strength. So far, the effect of treatment with levocarnitine on lower limb muscle strength has not been well described. This observational study examined the association between treatment with levocarnitine with the change in knee extensor strength (KES) in hemodialysis patients. Eligible patients were selected from the participants enrolled in a prospective cohort study for whom muscle strength was measured annually. We identified 104 eligible patients for this analysis. During the one-year period between 2014 to 2015, 67 patients were treated with intravenous levocarnitine (1000 mg per shot, thrice weekly), whereas 37 patients were not. The change in KES was significantly higher (p = 0.01) in the carnitine group [0.02 (0.01–0.04) kgf/kg] as compared to the non-carnitine group [−0.02 (−0.04 to 0.01) kgf/kg]. Multivariable-adjusted regression analysis showed the positive association between the change in KES and the treatment with levocarnitine remained significant after adjustment for the baseline KES and other potential confounders. Thus, treatment with intravenous levocarnitine was independently and positively associated with the change in KES among hemodialysis patients. Further clinical trials are needed to provide more solid evidence.

SummaryThe main aim of this research was to compare differences in heart rate values (HR) of soccer players during small-sided games (SSGs) with different number of players. We assumed that the number of “neutral” player or players in small-sided games will significantly affect the intensity of SSGs and in this case the heart rate values of participating players. The experimental group consisted of older junior players from the FC DAC 1904 Dunajská Streda soccer club (n = 9). The heart rate values were evaluated on the basis of collected data, which we obtained using Polar sport testers and special software Polar Team2. In order to find out the statistical significance of the difference in heart rate was used the One-Way ANOVA and the Bonferroni post hoc test. The level of statistical significance we set at 5 %. We found out that with increasing number of “neutral” players’ the intensity of small-sided games gradually decreased. During SSG1 (3 vs. 3), we recorded the highest achieved average heart rate values of the monitored players, in average 171.33 ± 9.39 beats.min-1. This form of the SSGs was the most intense, but not statistically significant. Our recommendation is to employ SSGs in the systematic training process with different number of players, because we can adequately prepare the players for the match load itself. Attention need to be paid for the playing position requirements.

Background: There is increasing evidence that practicing tai chi or yoga can improve the elderly’s physical performance. This study aimed to compare the effects of tai chi and yoga on balance and leg muscle strength in the elderly. Material & Methods: This cross-sectional study involved 90 elderly persons who practice tai chi (n = 36), yoga (n = 23), and a control group (n = 31). The balance function was assessed using the single-leg stance (SLS) test, while leg muscle strength (LMS) was assessed using a leg-back dynamometer. A Chi-square, Spearman rank test, one-way ANOVA with LSD post hoc were applied. The significance was set at p<0.05. Results: One-way ANOVA showed a difference in LMS and SLS between groups (p<0.01). LSD post hoc analysis found the difference in LMS between tai chi and yoga (64.3 vs. 41.5, p<0.01) and tai chi and control (64.3 vs. 30.4, p<0.01). The difference was also found in SLS between tai chi and control (36.7 vs. 6.2, p<0.01) and between yoga and control (41.4 vs. 6.2, p<0.01). Conclusion: Elderly persons who participated in tai chi and yoga demonstrated higher LMS and SLS performance than the sedentary participants. The tai chi group showed better muscle strength than the yoga group.

Generation sub-groups have been and continue to be stereotyped as requiring different approaches in the workplace and elsewhere with regard to what keeps them motivated and satisfied. Two measuring instruments were distributed electronically to all staff of a South African Facilities Management firm. The one-way ANOVA was conducted with post-hoc tests to establish which factors display statistically significant differences between generations. The findings demonstrated that certain generation sub-groups have preferences for different types of reward, reward categories, and have different perceptions about what types of reward attracts, motivates and retains employees. The main recommendation is that the company needs to adopt a flexible approach to reward and recognition that allows employees to tailor their reward structure to their own needs.

This research was conducted to determine the effectiveness test of papaya leaf extract with a concentration of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% and 90% and 100% against staphylococcus epidermidis bacteria. Staphylococcus epidermidis is a gram-positive bacterium in the form of cocci and is harmful to humans. This research was conducted with an experimental method with a post-test only design and sampling with a purposive sampling method. The investigation of the effectiveness of papaya leaf extract against staphylococcus epidermidis was done by diffusion using paper discs, namely by calculating the diameter of the bacterial inhibition zone of paper discs that have been moistened with papaya leaf extract. The results of this study were analyzed out with the One-Way ANOVA test followed by the Post Hoc Test. The test showed that there were significant differences from each treatment given with a 95% confidence index. The bacteria treated with papaya leaf extract 100% against staphylococcus epidermidis had the highest average inhibitory zone power compared to other concentrations of 14.97 mm. The papaya leaf extract 100% has the best antibacterial effect compared to other concentrations because the best inhibitory zone power is found on those extract concentrations.
