Published: October 2018

Objective: To investigate the effects of eccentric hamstring training on strength measures and vertical jumping performance. Methods: 26 male basketball players aged 10–12 were divided into Nordic Hamstring Strength Training group (N=15) and control group (N=11). Training was conducted over a 5-week period during which both groups participated in basketball training. All participants underwent pre- and post-training testing comprising isokinetic concentric and eccentric knee extension and flexion strength and vertical jump performance. Results: The NHST group exhibited significant increase in eccentric hamstring strength (p< 0.05) and vertical jumping ability (p< 0.01) whereas the performance of the control group remained unchanged during that period. Conclusion: Including eccentric exercises into entire training program improve muscular strength and can help athletes to reach their highest potential so they produce greater muscular forces.

Published: October 2018

Background: Fatigue is thought to impact performance and may be a factor in injury mechanism. However, the full impact of a potentially fatiguing task on performance is unclear. Objective: To explore changes in maximum voluntary torque and electromyographic (EMG) activity following a sixty second isometric maximum voluntary contraction (MVC) of the quadriceps muscles and to follow the time course of any changes observed. Method: 21 subjects (14 males and 7 females) were recruited. Torque during brief maximum voluntary isometric contractions of the quadriceps muscle group was recorded in right and left legs using a Cybex Norm Isokinetic Dynamometer before, during and at intervals after a 60 second isometric fatigue task. EMG activity of the vastus medialis, rectus femoris and vastus lateralis was also recorded synchronously. Results: Mean peak torque was significantly (p< 0.05) lower in both legs at the end of the fatigue task. However, 10 minutes following the cessation of the task, it had increased and was significantly higher than the pre-fatigue level. It remained higher until the end of the protocol (30 mins post fatigue). The EMG amplitudes decreased slightly compared to pre-fatigue values during the fatigue task, a few of which were significantly lower than those of the pre-fatigue task. Following the fatigue task, EMG amplitudes increased gradually and were significantly higher than those of the pre-fatigue task in all the muscles at the final time point. Median frequencies decreased significantly during the fatigue task and were similar to pre-fatigue values by 5mins post-fatigue. Conclusion: This study has revealed that both torque and EMG rise following a sustained isometric 60 second hold to higher levels than pre-hold and that this rise is maintained for up to 30 minutes. This rise however, was not associated with increased muscle firing frequency. The mechanisms behind this rise remain to be elucidated.

Published: October 2018

Background: In track and field, the load of impact, the coordination and the constraints on the ankle could result in adaptations of the ankle dynamic stabilization. These constraints could play a strengthening role and increase invertor and evertor strength also after a previous history of lateral ankle sprain. Objective: To compare the ankle invertor and evertor isokinetic strength in track and field athletes (i) with functional ankle instability(FAI), (ii) with history of lateral ankle sprain but without functional ankle instability, and (iii) without any history of lateral ankle sprain. Methods: Twenty-five track and field athletes (5 female and 20 male, 22 ± 5 years) were included in this cross-sectional controlled study, and divided into 3 groups for comparison: (i) athletes with FAI, (ii) athletes with a previous history of lateral ankle sprain, and (iii) a control group of healthy athletes. The dominant side ankle invertor and evertor isokinetic strength were evaluated concentrically at 120 and 30°/s while the evertor strength was also tested eccentrically at 30°/s. Results: No significant differences were indicated between the muscle strength of the three groups, except for the concentric evertor peak torque and the evertor-to-invertor ratio (EIR) at 30°/s (P < 0.05). The concentric evertor peak torque and EIR at 30°/s were significantly lower in the group of athletes with a previous history of ankle sprain than in the control group (P <0.05). Conclusion: Functional ankle instability and/or history of lateral ankle sprain in track and field athletes were not associated with strength weakness of the invertor or evertor muscles. However, as the EIRs were higher than 1.0 for the healthy track and field athletes and those with FAI, it is suggested that the track and field constraints result in adaptations of the ankle dynamic stabilization and then influence invertor and evertor strength balance.

Authors: Koç Hürmüz , Aycan Kenan 
Published: October 2018

Objective: The purpose of this study was to examine hand grip strength in individuals with and without the palmaris longus (PL) muscle. Method: Sixty-eight participants from different sports volunteered to participate in this study. The mean age of participants with PL (PL+) or without (PL-) was almost identical, 21.9 ± 1.9 y and 21.7 ± 1.5 y, respectively. Length of dominant arm, width of elbow, wrist and hand grip strength of the subjects were measured using measuring tape whereas a hand grip dynamometer was used to measure hand grip strength. Results: The wrist-width, forearm flexion position and the hand grip strength differed significantly between the groups (p < 0.05). Conclusion: This result indicates that the PL may enhance hand grip strength.

Published: October 2018

Purpose: The aim of this study was to assess the relationship between the free-throw percentage, joint position sense, and muscle torque in professional basketball players. Methods: Eleven professional basketball players participated in the study, with each subject acting as their own internal control by using the non-dominant side. Knee and shoulder joint of the players were evaluated bilaterally. Flexion and extension peak torque of the knee were evaluated isokinetically system. In addition flexion/abduction/external rotation (F/ABD/ER) and extension/adduction/ internal rotation (E/ADD/IR) diagonal pattern peak torque of the shoulder were measured. The joint position sense of both knees and shoulders were evaluated using an active angle reproduction. Thirty, 45, 60 and 75° target angles were used for knee and 160, 135, and 120° target angles were used shoulder. The free-throw percentage of the players for 40∼matches in the 2009–2010 season was taken from the Turkish Basketball League official website. The relationship between the peak torque of the muscles, joint position sense, and the free-throw percentage was evaluated. Results: There were no significant differences in the peak torques of the knee and shoulder muscles and joint position sense between the dominant and non-dominant sides (p> 0.05). There was a significant correlation between the free-throw percentage and the peak torque of the shoulder muscles during the F/ABD/ER pattern at 60°/s in the dominant side of the players. There was a borderline trend to significance between the free-throw percentage and the shoulder joint position sense (eyes-closed and at 160°) in the dominant side. There was a borderline significant correlation between the free-throw percentage and the knee joint position sense (eyes-open and at 75°) in the dominant side. Conclusions: The effect of proprioceptive and strengthening exercises on the free-throw percentage is still unknown. Further comprehensive studies are warranted to analyze the effect of proprioceptive and strengthening exercises on the free-throw percentage in elite basketball players.

Aim: To evaluate bone mass in female basketball players and the relationship between bone mineral density (BMD) and isokinetic muscle strength. Methods: We investigated 29 female basketball players, age 21.9 ± 9.1 years, training for about 6–8 hours per week. The reference group consisted of 22 non-active female, age 21.4 – 1.5 years. BMD was measured using dual-energy-X-ray absorptiometry in total body, lumbar spine, the whole femur and humerus. Isokinetic peak torque of the quadriceps and hamstring muscles were measured at 60 and 180°/s. Osteocalcin (OC) and cross-linked C-telopeptide (CTX) were measured by radioimmunoassay and electrochimiluminescence, respectively. Results: Compared to the controls, the basketball group had significantly (P <0.001) a higher BMD in the total body (11.6%), the lumbar spine (9.83%), the dominant femur(16.8%), the non-dominant femur (15.8%) and the dominant humerus(8.47%). The female basketball players had also significantly higher peak torques at both isokinetic velocities (60 and 180°/s) and for both lower limbs. All muscle peak torque measured for the female basketball players were significantly correlated with correspondent leg BMD and for both velocities tested. However, no significant correlations were noted for the control group. Values of formation (OC) and resorption (CTX) markers were significantly higher in the athletic females (P < 0.01 and P < 0.05, respectively). Conclusion: Our results show clearly that practice of basketball is associated with the improvement of bone mass. In addition, the most important finding of our study is that isokinetic muscle strength seems to be correlated with correspondent BMD in female basketball players.

Frequency and temperature dependence of the hysteresis loops (both major and minor hysteresis loops) of well-known materials such as pure Fe and pure Ni in the as-cast state and after a heat treatment, were measured and analyzed. Furthermore temperature dependent magnetostriction of the as-cast and annealed Ni sample were measured and residual stresses were estimated by assuming the magnetoelastic energy as the origin of coercivity H c. The hysteresis measurements were made on fully automized hysteresigraph which is handled by a labview program. The system works with ring- or frame-shaped samples in the frequency range from 0.1 Hz to 2 kHz and in the temperature range from −77 K to 493 K.

In scientific publications and conducted studies, the possibility of representing logical functions (LF) in alternative forms of representation is demonstrated, the characteristic feature of which is a polynomial entity, which reduces to the representation of LF in the form of series different from the traditional classical representation by adding members of a series - in particular, for an algebraic form, the addition is carried out algebraically with weight coefficients, and in the case of the use of the Reed-Muller form addition is made for mod 2. The results of complete sets of logical functions studies proved that the traditional classical form does not always ensure the minimality of indicators for the structural complexity of the logical functions implementation, which makes relevant further steps in determining the optimal forms for representing logical functions in the problems of discrete devices analysis and synthesis. The implementation of the combination scheme for a given logical function from n arguments is carried out by some set of variants of structures. In problems of analysis and synthesis of combinational circuits of discrete devices it is necessary to evaluate the quality of their possible structures, to provide identification and selection of the most successful or optimal ones. The concept of the logical functions optimal form of representation is presented in the article as an important direction of structural perfection of discrete devices on the basis of their logical functions realization in alternative forms of representation. The existence of the OFR-concept, which takes into account different forms of representation, makes it highly efficient to use alternative forms of logical functions representation from the point of the structural complexity parameters of the combinational schemes implementation in comparison with traditional classical form. The article outlines the factors for the further improvement of the OFR-concept by filling it with new scientific achievements, which will allow to completely or partially remove difficulties with the introduction of the optimal FR into broad engineering practice

The requirements to the quality of higher education in Ukraine and in the world are rising. This means that the quality of strategic management of HEIs is a guarantee of successful implementation of the state reform of higher education in Ukraine. In this conditions, there is no doubt that the adjustment of the universities’ strategies is inevitable if they are going to adapt to new challenges. The article is devoted to the evaluation from the process approach of the management of effectiveness of the university's strategy as a project-oriented organization. the matrix "competitive position / growth trend" for the universities of the Kharkiv region in 2017 was constructed. A comparative assessment of the activities of universities of the Kharkiv region in 2017 has been carried out for three components: quality of scientific and pedagogical potential; quality of training; international recognition. The paper investigates the hypothesis of a connection between the position in the official rating of universities and the quality of its strategic plan. The data of the Consolidated rating of Ukrainian universities and the rating of CEDOS for 2015-1017 are used. Correlation connection with time lag between these indicators is proved. The rank correlation increases with the increase of the time lag (in this paper the range of the time lag {0; 1; 2} was investigated, due to the availability of empirical data). The research evaluated the degree of correlation of the observed phenomena (the content of the strategic plan and the university’s position in the rating) by Spearman’s rank correlation coefficient. The colligation of the studied factors was assessed applying the Chaddock’s scale. The results of the correlation analysis of the relationship between the group of indicators "The main management processes of the university" and the group of calculated indicators in the structure of the indicator "Content of the strategic plan" confirmed the correctness of the using the rating methodology by the CEDOS Center. The authors conclude that the management of an organization such as a university is advantageously carried out from the standpoint of the process approach

The role of syntax in the productivity of German N+N compounds. A diachronic corpus study
Authors: Kopf Kristin 
Published: October 2018

This paper studies the morphological productivity of German N+N compounding patterns from a diachronic perspective. It argues that the productivity of compounds increases due to syntactic influence from genitive constructions ("improper compounds") in Early New High German. Both quantitative and qualitative productivity measures are adapted from derivational morphology and tested on compound data from the Mainz Corpus of (Early) New High German (1500–1710).

Korpusbasierte Untersuchung der Wortbildungsaffixe im Luxemburgischen. Technische Herausforderungen und linguistische Analyse am Beispiel der Produktivität
Authors: Sirajzade Joshgun 
Published: October 2018

The project WBLUX (Wortbildung des moselfränkisch-luxemburgischen Raumes) at the University of Luxembourg aims at the investigation of Luxembourgish word formation through different text sorts and genres. In order to achieve this goal the compilation of an annotated corpus is needed. This article gives an example for benefits of using a corpus with annotations like parts of speech, lemmata and word formation affixes in the analysis of productivity of some selected word formation affixes of Luxembourgish. Then it describes how one can achieve such a corpus from a technical point of view. This includes the choice of corpus format, of a database platform and the designing of programs needed for the annotation process of word formation itself. This article also suggests new corpus linguistic approaches for research of word formation like analyzing the usage of word formation bases in the entire corpus or performing context analysis in order to determine semantical functions of each suffix.
