ABSTRACT This study was designed to examine the metabolic power (MP) responses of football and futsal players to different small sided games (SSG). Twelve football and 12 futsal players participated in this study voluntarily. Maximal oxygen consumption(VO2max) and coach scoring (CS) were used for SSG player matching. Football and futsal players participated in two bouts of 2vs2, 3vs3 and 4vs4-SSG in random order. Kinematic and MP variables during SSG were measured by using GPS. To determine the effects of branch and SSG on each dependent variable of total distance (TD), relative TD (TDRel), MPaverage, relative TD in four different MP levels, and negative and positive acceleration numbers, a main effects 2-way analysis of variance with Bonferroni post hoc was used. MPaverage was significantly higher in futsal players compared to football players (p = 0.000). TD (p = 0.000) and TDRel(p = 0.013) of futsal players was significantly higher compared to football players. Total deceleration and acceleration numbers during SSG were significantly higher for futsal players than football players (p = 0.026). MP requirements were independent of the game format (p > 0.05), except for 2vs2-SSG (p < 0.05), when the playing area per player was kept constant. The results of this study showed that external load indicators during SSG were higher in futsal players compared to football players.

ABSTRACT Using 120 years of Major League baseball data, we re-examine the apparent and widely presumed performance advantage of left-handers. We verify the previously known phenomenon that left-handers hit better than right-handers, but we show this advantage exists only because they face pitchers with the opposite hand far more often; they are not innately more talented. We find, however, that left-handed pitchers are indeed better than right-handed pitchers, and we show the perhaps unusual result that a player’s throwing hand plays a role in the quality of his batting. We further show that switch-hitting is largely ineffective, and we explore a symmetry puzzle in which batters of a given hand facing pitchers of a given hand do not bat similarly to batters of the other hand facing pitchers of the other hand. Taken together, we show that the handedness advantage in baseball is about more than the batting hand. Three handedness factors matter: the matchup advantage, the pitcher quality, and the natural handedness of the batter. Of the 40,320 possible rank orderings of the eight combinations of these three handedness factors, our theory predicts one specific order and finds that it indeed holds across the 1.8 million matchups of 15,000 players.

ABSTRACT Almost half of all possessions in elite Gaelic football originate from turnovers. However, understanding of what constitutes a successful possession following a turnover is limited. This study provides the first comprehensive performance profiles for closely contested Senior men’s intercounty knockout championship matches (final score deficit, ≤6 points), and characterises successful possessions following a turnover. Twenty-nine knockout matches from the 2020 and 2021 All-Ireland Senior Football Championships, including 1,257 possessions following a turnover, were analysed. Statistical differences between winning and losing performances were identified using paired sample t-tests (p ≤ 0.05) and Wilcoxon signed ranked tests (p ≤ 0.05). Binary logistic regression was used to model possession outcome following a turnover. Findings revealed that winning teams were significantly superior to losing teams in securing and retaining possession and demonstrated greater efficiency and productivity in converting possession into scores. Binary logistic regression identified possession duration and the number of attacking phases per possession as the most significant predictors of possession outcome. Prolonged possessions consisting of fewer attacking phases also resulted in a greater score return. These findings enhance existing theoretical understanding of the nature of possessions in Gaelic football and may have practical implications for coaches and performance analysts.

ABSTRACT The purpose of this study was to explore the relationship between gluteal muscle activity patterns and dynamic control of the knee joint during a high-risk single-leg landing task in badminton. Thirty-four badminton players perform a single-leg landing test after a backhand side overhead stroke. This test collected lower limb kinematics, ground reaction force, and gluteus muscle activity data using a marker-based motion capture system, force plates, and electromyography(EMG). The relationship between gluteus maximus(GMAX), gluteus medius(GMED), and knee flexion angle, valgus angle, extension moment, valgus moment, and tibial anterior shear force was analysed by Pearson’s correlation coefficient. The results show that Peak knee valgus was strongly and moderately positively correlated with the activity of the gluteus maximus(GMAX) and gluteus medius(GMED) muscles. Peak proximal tibial shear force was moderately positively correlated with gluteus maximus and gluteus medius activation. Our findings suggest a correlation between the gluteus muscles and the dynamic control of the knee joint during the impact phase of the single-leg landing task in badminton. Optimising neuromuscular control of the glutes may be beneficial in reducing the risk of Anterior Cruciate Ligament(ACL) injury in badminton players during single-leg landing tasks.

ABSTRACT The best golfers exceed the length and accuracy of their driver strokes. The distance and accuracy of the strokes are determined by the impact factors between the club and the ball. However, it is not known whether there are differences in the level and consistency of impact factors within high-level performance players. This study aims to determine the level and variability of impact factors during full swing and evaluate the differences between high-level golfers. Professional and elite players achieved significantly higher clubhead speed as opposed to skilled players, which subsequently caused higher smash factor and ball speed. They also produced significantly lower launch angle with eight iron and lower spin rate with driver. Unexpectedly, the difference in consistency was found only between professional and skilled golfers in the variation of the smash factor which led to a lack of consistency in ball speed. In general, the results indicate that all performance groups are able to consistently repeat the impact factors during the full swing; however, the level of the impact factors distinguishes professionals and elites from skilled golfers. This study therefore suggests that the focus should be primarily on the quality of the golf swing and subsequently on its repeatability.

ABSTRACT In artistic gymnastics, rule changes in the year 2006 aimed to reduce the dominance of difficulty while strengthening performance differentiation. Related research on scorings often refers to analysing the proportion of difficulty and execution scores. For this, several studies preferred analyses of punctual major competitions predominantly neglecting long-term effects on performance differentiation. Therefore, the present study aimed to examine the effects of the International Gymnastics Federation’s (FIG) modified performance rating system on the importance of execution and difficulty and performance differentiation in men’s world elite artistic gymnastics following rule changes. The results’ lists of the five recent Olympic Games (i.e. qualification competitions of Athens 2004, Beijing 2008, London 2012, Rio 2016 and Tokyo 2021) including the difficulty, execution and final scores of the TOP20-ranked gymnasts in each event were analysed. Compared to Athens 2004, results revealed significantly enhanced performance differentiation (p < .01) with the execution score nowadays to predict the final score (p < .01). However, both general findings need to be discussed with respect to apparatus-specific phenomena. We suggest these findings to reflect positive impacts of rule changes on performance rating in world elite men’s artistic gymnastics due to intended scoring tendencies.

ABSTRACT The aim of this research was to analyse the differences in performance indicators between outdoor and indoor professional padel tournaments according to the gender of the players, the round in the draw, the set number, and their result. Performance indicators (winning break points, errors, winning shots, winning smashes…) of 942 sets (402 matches) from the 2022 World Padel Tour (WPT) season were collected from WPT TV open access videos. Differences between outdoor and indoor tournaments in performance indicators according to the analysed variables were analysed through descriptive and inferential statistics. The results showed significant differences between outdoor and indoor tournaments in men’s padel with a higher number of winning shots (p < 0.001) in indoor matches, and in women’s padel with a higher number of smashes (p < 0.001), winning smashes (p = 0.003) and errors (p = 0.002), in outdoor matches. In addition, the rounds in the draw, the set number, and its result were found to be parameters that influence the performance indicators analysed according to the tournament (outdoor and indoor). These findings are of great interest, as they provide players and coaches with an understanding of the performance indicators that affect the style of play depending on whether the tournament is played outdoors or indoors.

ABSTRACT Sitting volleyball (SV) is a dynamic with short actions sport in the paralympic programme. The purpose of the study was to identify the volleyball skills that best discriminate between winning and losing an SV set, for both the genders. The data were collected from all sets played (N = 224) on the 2019 European men and women SV Championship. Cluster analysis established three types of sets according to the final score difference: 2–4 points (balanced), 5–11 points (semi-balanced) and over 11 points (unbalanced). Three-way MANOVAs were conducted to analyse gender, type of set and type of result differences for selected performance indicators. The analyses revealed significant multivariate differences across gender (p < .001), types of set (p = .014) and result (p < .001) and significant interaction effect of result with gender (p = .025) and type of set (p < .001). A follow-up discriminant analysis showed that setting and attacking were the most important skills for all sets. The results showed that in SV the attack is the most important factor, which determines winners and losers, even in balanced sets. In SV, the importance of skills across gender was similar to volleyball, while there were differences in the structure of the game compared to the sequential order of skills in volleyball.

Forty-one male adult judo athletes (23.3 ± 5.8 years old; 78.9 ± 11.6 kg; 174.7 ± 5.9 cm) underwent anthropometric measurements and a test battery to evaluate lower- and upper-body aerobic and anaerobic power and capacity, upper-body dynamic strength-endurance and performed one 5-min match simulation. The time-motion variables were recorded and used to determine the athletes’ pacing. Perceptual, physiological, and performance variables were used to estimate the actions during the match via multiple regression analysis. The association between the frequency of attacks and upper-body strength-endurance confirmed the relevance of developing this capacity for high-intensity actions during the match. Aerobic capacity and power were related to high-intensity actions during the match. Anaerobic power and aerobic capacity were negatively related to high-intensity strength-endurance actions across the match (grip time), while upper-body VO2peak positively influenced it. Groundwork time was determined by aerobic capacity, upper-body strength-endurance, and anaerobic power. However, the coefficient of determination for these relationships was low to moderate (i.e. 0.13–0.51). Thus, different combinations of physiological, perceptual, and performance variables could partially estimate frequency and time of high- and low-intensity actions during the match.
