In the sport performance structure of table tennis is sensor motor reaction time one of the most important factors for reaching top-level results, both in males and females groups. In this research we watched 23 female table tennis players from Slovakia; 9 mini cadets (12-13 years), 6 cadets (14-15 years) and 8 juniors (16-18 years). Girls were tested by modified agility test for table tennis players (Vacenovsky & Vencurik, 2013) with machine FITRO Agility check. Thus we gained their sensor motor reaction times. By Mann-Whitney U-test we studied differences between age categories, upper and lower extremities, dominant (forehand) and un-dominant (backhand) side, right and left-handed players. We used significance level p<0.05. In our research we did not confirm expected results that the older groups have shorter sensor motor reaction time. We also expected shorter reaction time of upper extremities comparing lower extremities; this was confirmed, though there was found statistical significant difference only in juniors group. Groups of mini-cadets and cadets have better (shorter) sensor motor reaction time from backhand side, while group of junior is better from forehand side. We also confirmed that left-handed players have slightly shorter reaction time.

ABSTRACT Aim To evaluate the effect of different chelating agents on the microhardness of the superficial dentin layer of the root canal lumen. Materials and methods Forty-two extracted single rooted teeth were instrumented, and the roots were longitudinally sectioned in a buccolingual direction to expose the entire canal extension. The specimens were randomly distributed in four groups according to the final irrigation: Glyde File Prep (Dentsply Maillefer, Ballaigues, Switzerland), RC Help (Prime Dental Pvt. Ltd, Mumbai, India), Endo Prep RC (Stedman Anabond, Chennai, India), Dolo Endogel (Prevest Denpro Ltd, Jammu, India). A standardized volume of 50 ml of each chelating agent was used for 5 minutes. Dentin microhardness was measured with a Knoop indenter under a 50 gm load and a 15 seconds dwell time. Data was analyzed statistically by one-way analysis of variance ANOVA and post hoc multiple-comparison test at 5% significance level. Results Statistically significant difference was detected among the chelating agents by one-way ANOVA. Glyde File Prep and Dolo Endogel chelating agents differed significantly (p < 0.0001) in reduction of dentin microhardness from RC help and Endo Prep RC. Conclusion Glyde File Prep and Dolo Endogel are significantly better than RC Help and Endo Prep RC in reducing dentin microhardness. How to cite this article Napte BD, Srinidhi SR.

It is known, reaction time increases with age. Agility time, enriched by a motor component is investigated less. Therefore the aim of this study was to determined age-related differences in disjunctive reaction-speed abilities, where the result is an agility time. Data were obtained by agility test adapted to the specific needs of table tennis using FiTRO Agility check device. Subjects of testing were table tennis players from 20 to 70 years devided into four age categories. We assumed a statistically significant differences between agility time in these categories. We assumed a significant relationship between agility time and age. One-way ANOVA indicated a significant differences in agility time between categories (F(2,46) = 10,2; p < 0,001). Pearson correlation coefficient indicated significant relationship between agility time and age (r = 0,53; p < 0,01. We found a significant difference between motor reaction to the forehand and backhand side. It was shorter to the forehand in each age category. Our study showed the age-related changes in disjunctive reaction-speed abilities.
