      Abstract: The present study aimed to investigate the relationships between personality traits and tactical knowledge of field hockey players. The sample consisted of 53 Brazilian female field hockey athletes. The collection instruments were the Big Five Personality Factors Inventory, the Self-Assessment Inventory of Tactical Skills in Collective Sports Games, and a sociodemographic questionnaire. The data were treated according to descriptive and correlational statistics. Percentage values were calculated when the variables showed significant differences. The normality and homogeneity of the data were verified by the Shapiro-Wilk and Levene tests, respectively. The partial correlation test, controlled by the position of the players, was used to analyze associations between the variables. A one-way ANOVA was applied to compare participants’ age and practice time with their field positions. The Kruskal-Wallis test was used to compare the positions of the players. The value of p<.05 was adopted for statistical significance. As a result, a moderate positive correlation was obtained between practice time and age; a moderate negative correlation of Neuroticism with age and practice time; moderate positive correlations between practice time and declarative and procedural knowledge. The Openness exhibited moderate positive correlations with declarative and procedural knowledge. The midfield players had higher scores in Extraversion when compared to the defensive players. In Agreeableness, the midfield players had higher scores when compared to defense and attack. The study allowed concluding that Openness was associated with the tactical knowledge domain.

      Abstract: The aim of this study was to investigate the role of parent-initiated motivational climate on athletes’ dispositional flow and sport engagement. For this purpose, a total of one hundred and eighty athletes (age, M=17.48, SD=3.39 years; sport experience, M=6.48, SD=3.75 years) voluntarily participated in this study. The participants were recruited voluntarily from team and individual sports. A personal information form, Parent-Initiated Motivational Climate Questionnaire-2, Athlete Engagement Questionnaire, and Short Dispositional Flow Scale 2 were used as the data collection tool. The data were analyzed by descriptive statistics, Pearson correlation analysis and stepwise multiple regression analysis. According to the Pearson correlation analysis, confidence, dedication, vigor, enthusiasm, global engagement, and dispositional flow were found to be positively and significantly correlated with parent-initiated task-involving climate. Parent-initiated ego-involving climate did not significantly correlate with any engagement or flow variables. According to the results of multiple regression analysis, parental task-involving climate significantly contributed to athletes’ confidence, dedication, vigor, enthusiasm, global engagement, and dispositional flow. Overall, the results showed that parents’ task-involving motivational climate contributed to athletes’ engagement and dispositional flow. In line with these findings some suggestions for parents are proposed. Key words: motivational climate, parent, dispositional flow, engagement

      Abstract: Differences between hands in motor performance are associated with differences in the interaction of inhibitory connections of homologous parts of the cerebral hemispheres. Modulation of these inhibitory connections in the right and left primary motor cortex (M1) may alter manual performance asymmetries. To investigate this assumption, eleven right-handed male university students performed a discrete aiming task in a digitizing tablet under three experimental conditions: dominant M1 inhibition, non-dominant M1 inhibition, and sham. The Transcranial Direct Current Stimulation technique was used to increase or decrease participants’ M1 excitability. We used a within-subject design, in which we counterbalanced the order of conditions and the order of the starting hand among participants. The performance-dependent variables were: reaction time, movement time, and radial error, while kinematic variables were: peak velocity, relative time to peak velocity, and number of discontinuities in acceleration in the final homing phase. Results showed changes in asymmetry related to reaction time, movement time, and relative time to peak velocity. The interaction between M1 modulation and hemispheric specialization produced specific changes in these variables. Taken together, these findings revealed that modulation of the dominant and non-dominant M1 affects manual performance asymmetries.

      Abstract: Research within sport science disciplines seeks to enhance performance via the combination of factors that influences the team’s periodization. The current study aimed to investigate the variations in training load (TL), and the consequential changes in fitness variables, based on the use of match difficulty prediction model (MDP), level of opposition (LOP), days between matches, and match location during 12 weeks in the competitive period I. Seventeen elite soccer players (age = 17.57 ± 0.49 years; body height 1.79 ± 0.05 m; body weight 72.21 ± 6.96 kg), have completed a Yo-Yo intermittent recovery test, a running-based anaerobic sprint test, a soccer-specific repeated sprint ability, and a vertical jump test to identify changes in players fitness. TL was determined by multiplying the RPE of the session by its duration in minutes (s-RPE). Training monotony, strain, and acute:chronic workload ratio (ACWR) were also assessed. A simple regression model was conducted and the highest variances explained (R2) were used. The LOP score explained most of the variance in ACWR (r= 0.606, R2=0.37). TL declined significantly when compared the match-day by the first three days and the last three days of the week. No significant difference was found in s-RPE between the high and low MDP factor. Strong negative correlations were reported between ACWR and LOP (r=-0.714, p<.01). In addition, we found a significant improvement in repeated sprint ability, aerobic and anaerobic fitness variables between pre- and post-test in fatigue index (d=1.104), best testing time, ideal time, total time and mean-best (d=0.518-0.550), and aerobic and anaerobic fitness variables (p<.05), respectively. The MDP could facilitate the training prescription as well as the distribution of training intensities with high specificity, providing a long-term youth player’s development and allowing teams to maintain optimal fitness leading into more difficult matches.

      Abstract: E-sports can be defined as an electronic sports form and is growing at a rapid pace worldwide. E-sport requires high-speed reactions during all games. The purpose of this study was to evaluate auditory, visual and aim reaction times in different duration of game playing in e-sport players. Fifty-three participants were assigned into two groups according to their playing time which was either more or less than 14 hours per week. The participants were tested for auditory reaction time with online website at, visual and aim reaction time on website of There were statistically significant differences in visual (p<.001) and aim (p<.001) reaction time between the groups, whereas in auditory reaction time no significant difference was found (p=.397). The visual and aim reaction times were higher in the gamers who play more than 14 hours in e-sport. Our study showed that visual and aim reaction time was more affected from game playing time than auditory reaction time in e-sport gamers. Playing e-sport may have positive effects on visual and aim reaction time in young population. Key words: eSports, visual reaction time, aim reaction time, auditory reaction time

      Abstract: Padel is a complex sport within which performance relies on the interrelation of multiple factors such as physiological and physical capacities, psychological skills, and tactical and technical knowledge. Padel match involves intermittent whole-body efforts, evidenced by a large number of strokes and repeated high-intensity running actions such as accelerations, decelerations and changes of direction. Due to its recent creation, little is known about the activity and energy demands of padel match play. The purpose of the present study was to systematically review physiological demands of padel match play by assessing parameters related to external load, such as notational analysis or time-motion studies, and internal load through the analysis of physiological responses during the match. The systematic review process was conducted in accordance with the PRISMA guidelines. The electronic databases PubMed, Scopus and SportDiscus were searched using: (“padel” OR “pádel” OR “paddle tennis”). Twelve papers matched the inclusion criteria, from which four addressed internal load, six external load, and two analyzed both. A total of 203 padel players across all competition levels participated in the 12 selected studies. Study outcomes have probed prevalence of moderate physiological responses, low contribution of anaerobic glycolytic processes to supply energy, VO2 not being a limiting factor, and moderate to relatively high perceived effort rate. The highest game durations were found in professional players. Work-to-rest ratios reaffirm the intermittent nature of padel. Distance covered per set and match as well as speed are reciprocally proportional to player’s standard level. Key words: physiology, training load, paddle tennis, PRISMA

      Abstract: A low physical fitness and incorrect technique could result in muscle strength imbalance and poor dynamic/ static balance in handball players. This study aimed to evaluate the muscular and functional performance of lower limbs in female handball athletes. Twelve female handball athletes performed isokinetic tests at 60°/s, 120°/s, 180°/s, and 240°/s for the knee’s extensor and flexor muscles and functional tests for lower limbs. Regarding the muscular performance, there were no differences between the limbs in the knee’s muscles’ peak torque, while the values of the conventional ratio were below the recommended. With respect to the functional tests, no significant changes were observed. On the other hand, the composite score of the Y-Balance test demonstrated values below the suggested. Overall, the results showed that young female handball athletes had symmetry between the limbs in the muscular and functional performance; however, there was a tendency to muscle imbalance (hamstrings weaker than quadriceps), and dynamic balance deficits that might increase the risk of musculoskeletal injury.

      Abstract: The aim of the study was to explore the service round technical-tactical performance indicators of three phases discriminating the match result and the two match forms. The statistics of 72 professional men’s singles matches of the 2018 international competitions were collected. A chi-square test was used to assess the relationship between match form, match outcome and service round result. Afterwards, a two-way ANOVA was performed to evaluate the effect of match form (SHM: match between players of the same handedness and OHM: match between players of the opposite handedness) and match result on three evaluation indices of thirteen technical-tactical indicators. The results displayed that: (1) there was a weak relationship between the service round outcome and match form for both the winning and losing players (p<0.001, ES=0.12); (2) the winners outperformed the defeated players by a higher technical effectiveness in all three phases with small to moderate effects (p<0.05, ES:0.50-1.00) at both match forms; (3) the usage rate of performance indicators of the first four strokes phase and six strokes above phase distinguished the SHM matches from the OHM matches by small to large effects (p<0.05, ES:0.50-1.26). This study offers insights for practitioners to comprehend the technical-tactical aspects that are deciding for performance when competing against different types of opponents and to make effective training plans and match strategies.

      Abstract: The purpose of this study was to examine the load of regular players and floater players in a specific small-sided game. Twenty semi-professional soccer players performed one 4vs4+2, modifying the position of the floaters (internal, external, zone, square and without floaters). Total distance covered, distance covered at speeds between 7-13.9 km·h−1, 14-17.9 km·h−1, and ≥18 km·h−1, accelerations and decelerations between 2.5-4 m·s−2, maximal and mean heart rate (HR) and rating of perceived exertion (RPE) were analyzed. Internal floaters achieved greater total distance covered, accelerations and RPE than in any other position. Internal and external floaters achieved more distance covered at 7-13.9, 14-17.9, >18 km·h-1 and HR than zone and square floaters. With internal floaters, regular players covered more distance covered >18 km·h-1 than in any other 4vs4+2 format, and with internal and external floaters regular players covered greater total distance and distance at 14-17.9 km·h-1 than without floaters or with zone or square floaters. Regular players showed
      greater total distance covered, distance covered at 7-13.9, 14-17.9, >18 km·h-1, accelerations and RPE than floaters in all 4vs4+2. These data showed that floater position in 4vs4+2 game influenced the internal and external load of both the regular players and the floaters.

      Abstract: The aim of this study was to investigate the ankle and knee stiffness and passive torque in individuals with diabetes mellitus type 2 (DM2), with and without diabetic peripheral neuropathy (DPN) at different speed of motion. Forty-nine male individuals of a similar age were studied (17 with DM2 without DPN, 15 with DM2 and DPN, and 17 controls). Knee and ankle flexion and extension passive torques were assessed on an isokinetic dynamometer at 5°/s, 30°/s, and 60°/s. Our results showed that the individuals with DM2 exhibited greater knee stiffness compared to the controls and the individuals with DPN presented greater ankle stiffness and passive torque compared to the controls and those with DM2 without DPN. The mechanical impairments at the ankle passive structures were most evident at low speeds while the knee alterations were at 30°/s and 60°/s. Although the presence of DPN was a key factor for the increased passive ankle stiffness and torque, it was not related to the increase in the knee passive stiffness. Preventive measures for avoiding stiffness and motion impairments at the ankle and knee could be adopted in the early stages of DM2.

      Abstract: To
      The Editor I would like to congratulate the authors (Lin, Matheus, Lin, & Lin, 2021) on their article, which I read with great interest. Tennis remains a unique interceptive sport, with the serve being the most complex and crucial point in the modern game both for the server and the receiver alike. It is an easy point if struck right; but also, a big loss if it is broken. It remains the receiver’s first and foremost anticipation task in the point and offers the least amount of response time for the intended task completion (Abernathy, 1991). Multiple studies have shown that pre-racket-ball contact information improves prediction accuracy (Farrow & Abernathy, 2003; Farrow, Abernathy, & Jackson 2005). Lin et al (2021) point out that skilled players can anticipate serve direction and placement from precontact visual information by focussing on the trunk, upper body, and the ball. Their methodology could not distinguish between these three areas of the body. A metanalysis has suggested experts generally employ fewer fixations but with longer duration (Mann, Williams, Ward, & Janelle, 2007). Hence, it is possible that the experts focussed on one of these (the trunk, upper body, and the ball) for longer while receiving the serve. A mixed methods study that utilises qualitative interviews immediately after the in-situ experiments, along with video recordings of the serves just received, might provide more granular data of what the expert players really focus on while receiving serves. Furthermore, tennis is also unique because the server has a second serve to play out the point, should the first one be a fault. Three kinds of serves have been identified in the literature – the flat, underspin or the kick serve (Kovacs & Ellenbecker, 2011). While the first serve is usually flat, the server sacrifices speed for accuracy in the 2nd serve to make the return more challenging and this usually involves spinning the ball on the racket head. Lower trunk position and muscle activation patterns do not change between the spinning and flat serves (Kovacs & Ellenbecker, 2011); instead, it has been suggested that the racket face angle differs between the various kinds of serves (Elliott, Reid, & Crespo, 2009) and it is possible that most players will have to change the trajectory of the ‘ball toss’ to facilitate the spin serve. Thus, capturing ‘ball toss’ information may provide additional perceptual cues when receiving serves. As a player (in, what I believe, the expert category) I know that the intention of both the server and the receiver will differ between the 1st and 2nd serve as well. For the receiver, the intention of returning the first serve may be perhaps just to get it back deep in the court on the other end and keep the ball in play. The approach to the 2nd serve is totally different – attack it and make it more challenging for the server to continue the point. Considering that perceptual-cognitive expertise literature suggests that corresponding decision-making is essentially dependent on the task and motivation (Williams, Davids, & Williams, 2000), evaluating the 1st and the 2nd serve in-situ situations may reveal differential results, especially in experts; and if so, this will have a potential to help novices further learn the nuances of tennis.

      Abstract: The image obtained by static ultrasonography (US), despite being a validated measure to identify muscle thickness (MT), has a visualization capacity limited by the size of the transducer. The extended field of view (EFOV) is a more recent technique of obtaining muscle images by the US, which allows observing MT over the entire length of the muscle. The purpose of the study was to determine the reliability and the intra- and inter-rater error of the MT measurement in the proximal, medial and distal portions of the vastus lateralis using the EFOV US. Twenty-five men (age = 24 ± 4 years) paid a visit to the laboratory. Two independent US technicians identified the anatomical landmarks and collected the images using EFOV US, with a 4 cm linear transducer, 10 MHz frequency and 6 cm image depth. After all collections, a third researcher codified the images, which were sent to two independent image raters. After a week, the images were shuffled, recoded and sent back to the same evaluators. The values of the typical error of the measurement, coefficient of variation and intraclass correlation coefficient intra and inter-rater ranged between 0.01 and 0.03 cm, 0.47 and 2.32%, 0.990 and 0.998, respectively, for the two evaluators. The Bland-Altman analysis indicated high agreement and homoscedastic error of all comparisons. The high reliability and low errors observed, less than the increments typically found in training studies, reveal the great potential for EFOV US to determine MT in different portions of the vastus lateralis muscle.

      Abstract: In order to maintain physical fitness during the COVID-19 quarantine, we designed a short-term intervention with one body-weight exercise – burpees. Thus, the aim of this study was to understand level of feasibility and potential benefits of our protocol to different variables in young adults during the COVID-19 quarantine. An online 4-week intervention was administered to 13 young adults (age 22.5±1.39 years, weight 71.8±10.1 kg). The main phase of each session consisted of burpees, a calisthenics body-weight exercises. The training was administered daily. Data regarding quality of life (QoL), body composition, posture, heart rate variability (HRV), cardiovascular health, and strength were collected before and after the intervention period. Participants’ QoL significantly increased after four weeks (p=.025). Also, participants’ strength improved, assessed by the push-up test (p=.017). Systolic blood pressure showed no difference between the pre- and post-measures, while a significant reduction was found in diastolic blood pressure. The HRV assessment showed increased mean RR (p=.005) and RMSSD (p=.014) and decreased mean HR (p=.004) (in the time domain). For the frequency-domain variables, no significant difference was found. No significant changes were noted in body composition, posture, handgrip strength and countermovement squat jump height. Our preliminary results suggest that the 4-week daily online burpees intervention is a feasible method that could improve QoL, upper body strength and HRV in young adults. This non-time-consuming approach could be easily administered to promote healthy living and counteract physical inactivity during COVID-19 restrictions thanks to its feasibility, short duration, and low cost.

      Abstract: The objectives of the present study were: (i) to compare beach handball game-related statistics by match outcome (winning and losing teams), and (ii) to identify characteristics that discriminate performances in the match. The game-related statistics of the 72 women’s matches played in the VIII Women’s Beach Handball World Championship (2018) were analysed. The game-related statistics were taken from the official Web page. A validation of the data showed their reliability to be very good (the inter-observer mean reliability was α=0.82 and the intra-observer mean was α=0.86). For the differences between winning/losing teams a parametric (unpaired t-test) or non-parametric (Mann-Whitney U test) test was applied depending on whether the variable met or did not meet normality, respectively. A stepwise discriminant analysis was then performed to determine the variables that predicted performance (victory or defeat). Five variables showed differences between the winning and losing teams: total points (p<.001; ES=1.09), technical faults (p<.001; ES=‑0.96), the number of players with either negative (p<.001; ES=‑0.86) or positive (p<.001; ES=1.05) valuations and overall valuation (p<.001; ES=1.29). The predictive model correctly classified 80.6% of the matches using two variables (Wilks’s λ=0.618; canonical correlation index=0.618): overall valuation and GK shots.

      Abstract: A detailed review of literature revealed that there is no study of the influence of different types of loads on the performance of a bilateral vertical jump examined on subjects of the same type of F-v profile. Therefore, the aim of this study was to evaluate the influence of two different load-types on the squat-jump performance in force-deficient subjects. During the seven-week training program, the 15 participants of force group performed a half back squat with a load of 80-85% 1RM, while the 15 participants of velocity group performed squat jumps with an unloading of 25% of body weight during the same period of time. The force group significantly improved height of the squat jump (+12.43 ± 6.98%; p <0.001), with a large effect (ES = 1.92 ± 0.72), while in the velocity group were recorded non-significant change (+2.02 ± 5.92%; p = 0.26), with a small effect (ES = 0.30 ± 0.60). These results in the force group were accompanied by a significant optimization of the F-v profile (+31.53 ± 34.91%; p = 0.003), with the attribute of large effect (ES = 1.10 ± 0.65), and the velocity group again recorded non-significant change (-2.20 ± 34.34%; p = 0.70), with a trivial effect (ES = -0.13 ± 0.60). The results of the force group support the hypothesis of the effectiveness of a training program aimed at developing a deficient component of the F-v profile.

      Abstract: The aim of this paper was to present the development of the journal Kinesiology – International Journal of Fundamental and Applied Kinesiology over the five decades of its publication through the analysis of the articles using bibliometric indicators. The sample consisted of 1083 articles published over the period of 50 years, from the 1st volume in 1971 until the 52nd volume in 2020. The analysis of the articles revealed that the most common articles were original scientific papers, while the least represented articles were categorized as conference papers. From 1971 to 1996, most articles were written in the Croatian language, but since 1997, the articles have been written only in the English language. An analysis of the cited references in the last decade of the journal’s publication was made in order to point out the patterns of scientific communication in kinesiology and to determine the recognizability of the published papers at the international level. Since 2006, greater visibility of Kinesiology – International Journal of Fundamental and Applied Kinesiology has been enabled by providing access to full texts of publications through the Portal of Scientific Journals of Croatia – Hrčak, whereas the articles published until the end of 2005 were retrogradely digitized.

      Abstract: Individual biathlon competition as an event consists of a number of segments (variables), i.e. cross-country skiing time, range time, so-called time difference, and shooting accuracy. In the research part, the study analysed the interrelations of these variables and their correlations with competitive performance at the Biathlon World Championship individual competition. Regression analysis showed that total cross-country skiing time was the most important determinant of competitive performance (55%). Total shooting performance prone and standing explains 39.5%, total range time accounts for 5% of the criterion variable, and time difference for 0.5%. The contestants hit 80.5% of all targets in this competition. Factor analysis determined seven factors that logically completed the competition outcome in a biathlon individual competition. These factors are: cross-country skiing performance; shooting time and range time; time difference; accuracy shooting 1 and total time in lap 1; accuracy shooting 2 and total time in lap 2; accuracy shooting 4 and total time in lap 4; and accuracy shooting 3 and total time in lap 3. Although we found in this competition a somewhat dominant contribution of the cross- country skiing itself to the final competitive performance, shooting accuracy is also very important in an individual biathlon competition. The results of men’s individual biathlon competitions at the last Olympics and World Championships show that it is still possible to win a medal with only one missed shot (two missed shots can only be afforded by the rare biathletes who are extremely fast skiers).

      Abstract: The objective of this study was to design and validate an observational instrument to determine the influence of the pivot on tactical performance in handball. The process consisted of five stages. In the first two, a combined instrument using field formats and category repertoires was designed. The third stage consisted of validating the content by consulting a panel of highly qualified experts. The fourth phase produced reliability indices, according to Cohen's Kappa test, for both inter-observer and intra-observer performance, of over .86. Finally, the instrument was applied to a pilot study; a correlational study using Pearson's Chi2test yielded very significant dependence coefficients (p <.001) among variables, confirming the usefulness of the instrument in the search for tactical performance indicators related to the pivot.

      Abstract: The purpose of this review was to gather studies that reported the impact of COVID-19 restrictive measures on physical activity and sedentary behavior in children and adolescents, and to present key findings. The search for articles was performed in three databases of scientific literature: PubMed, Scopus, and Web of Science. We included articles that reported a change in the amount of physical activity and/or sedentary behavior during COVID-19 restrictive measures compared to the period before restrictive measures. The quality of the articles was assessed using the Newcastle-Ottawa Scale. The search returned 1391 hits, of which 23 articles were included in the review. The studies showed that participation in physical activity predominantly decreased (in 17/23 studies) and sedentary behavior predominantly increased (in 16/17 studies). The results regarding the reduction of physical activity were the most consistent for moderate to vigorous physical activity, while the direction of change was mixed for some types of physical activity (e.g., exercise, walking). The results regarding sedentary behavior were mostly consistent in terms of increasing the total amount of sedentary behavior as well as types of sedentary behavior (e.g., watching TV, using tablets). This review showed that COVID-19 restrictive measures have further increased the issue of insufficient physical activity and excessive sedentary behavior among children and adolescents. There is a need for the development of interventions for maintaining/increasing physical activity among children and adolescents that would be suitable for implementation during the future pandemics and other similar crisis situations.
