Purpose. research on empirical aesthetics suggests that specific kinematic parameters are related to the perception of motion aesthetics. Furthermore, an observer’s expertise seems to be related to the perception of motion aesthetics when complex biological motion stimuli are present. the central aim of this study was to investigate whether the amount that specific body parts moved during a complex motor skill was related to the perception of motion aesthetics in observers with different levels of sensory-motor expertise. Methods. Overall, 36 participants divided into 2 groups (18 dancers and 18 non-dancers) were asked to indicate their perceived motion aesthetics when they watched stick-figure video sequences of 3 different semi-standardized dance skills. the stick-figure video sequences were generated from original motion stimuli, and motion aesthetics were measured via Likert scales. Results. the perception of motion aesthetics in relation to the amount that specific body parts move is skilland expertisespecific. Dance poses are perceived similarly by dancers and non-dancers, but motion aesthetics during dance jumps and turns are perceived differently. Furthermore, the amount that specific body parts move affects whether the observer perceives the motor skills as more or less aesthetic. Conclusions. the observer’s sensory-motor expertise regarding the observed motor skills can shape their perception of motion aesthetics. the findings of this study demonstrate that there is a skilland expertise-specific relationship between motion kinematics and motion aesthetics.

Inertial measurement units (IMUs) have been extensively used for measuring human motion. One particular outcome of interest in sports is vertical jump height, which is assessed in specific performance tests or actions occurring in training or match scenarios. This systematic review aimed to (1) identify and summarize studies that have examined the validity of wearable wireless IMUs for measuring jump height and (2) identify and summarize studies that have examined the reliability of wearable wireless IMUs for measuring jump height. A systematic review of the Cochrane Library, EBSCO, PubMed, SPORTDiscus, and Web of Science databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. From the 596 studies initially identified, 30 were fully reviewed, and their outcome measures were extracted and analysed. Among the 16 different IMU models, 15 were considered valid, with only one device not validated. Of the 7 IMUs that were tested for reliability, all were considered reliable for measuring jump height. In general, however, despite these findings, IMUs are not considered accurate enough to detect small changes in performance. Also, generalizations were not possible for athletic populations given the lack of studies with such samples. in the abstract an informative and balanced summary of what was done and what was found (item 1).

Purpose. The main purpose of this study was to investigate changes in the tactical-technical behaviour of football goalkeepers (GKs) across 5 small-sided games (SSGs) formats with temporary numerical variability. Methods. The sample involved 4 male under-17 GKs from the same team aged 16.1 ± 0.52 years. Three sessions were held on 3 different days to collect information. On each day, the 10-minute SSGs exercise with temporary numerical variability was repeated twice. The numerical ratio of players changed every 2 minutes without interrupting the practice. The exercise always started with a situation of 3 vs. 3 + GK (‘+ GK’ for both teams in each format), going through 4 vs. 3 + GK, 5 vs. 3 + GK, 3 vs. 4 + GK, and 3 vs. 5 + GK. Results. The 3 vs. 3 + GK format and the numeric superiority by 1 and 2 (4 vs. 3 + GK and 5 vs. 3 + GK) induced fewer defensive tasks in comparison with numeric inferiority (3 vs. 4 + GK and 3 vs. 5 + GK). From an offensive perspective, 3 vs. 3 + GK caused more offensive tasks in comparison with numeric superiority by 1 and 2 (4 vs. 3 + GK and 5 vs. 3 + GK). However, the game formats in numeric inferiority (3 vs. 4 + GK and 3 vs. 5 + GK) induced more offensive tasks. Conclusions. This study suggests the use of temporary numerical variability SSGs to increase offensive and defensive GK tactical-technical behaviour.

Purpose. balance is a highly demanded motor ability in artistic gymnasts; however, it is unknown what type of training can improve this variable. The purpose was to determine if Star Excursion balance Test (SEbT) and neuromuscular (NM) trainings are more effective than conventional artistic gymnastics training (CONV) for improving balance control in female artistic gymnasts. Methods. Overall, 33 female artistic gymnasts were selected and randomly assigned to 3 training groups: CONV, SEbT, or NM. The Y-balance Test evaluated balance control. ANOVA (group × time) with repeated measures was used to compare the effects of training. Results. In the dominant lower limb, significant pre- and post-intervention differences were observed for SEbT training in the posteromedial direction ( p = 0.0003; % change = 13.4), as well as in NM in the anterior ( p = 0.0001; % change = 23.9), posteromedial ( p = 0.0001; % change = 23.1), and total index ( p = 0.0001; % change = 17.8) of the Y-balance Test. Moreover, NM training presented significant differences compared with CONV ( p = 0.0001; % change = 14.0) and SEbT ( p = 0.0001; % change = 12.8) in the posteromedial direction; it also exhibited differences compared with CONV ( p = 0.0392; % change = 8.8) and SEbT ( p = 0.0065; % change = 11.3) in the total index. Conclusions. NM training results in a significant improvement in balance control compared with CONV and SEbT training in female artistic gymnasts.

Purpose. How demands of precision influence the performance during alternated discrete touching is not well established in the literature. Hence, we compared both hands performance during alternated touching, manipulating the precision demand. Methods. Overall, 23 right-handed adults participated in this study. the first task consisted of alternated touching with a pencil on both sides of a blank paper, performing as fast as possible, considering the first touch as reference for the next ones. Subsequently, touch dispersion and width were measured, and circular targets were drawn with those proportions. the second task consisted of performing as many hits as possible inside those targets. Apart from the delimitated target, increasing precision demand, the task parameters were equal. Results. Movement time increased and the number of touches decreased from the first to the second task. However, the preferred hand displayed greater reductions in performance. Conclusions. the perceptual constraint of adding a visual target affects motor control parameters in alternated touching, causing decrements in performance in both hands, but more evidently in the preferred right hand.

Purpose. In daily living, hands are the basic organs for manipulative tasks of the human body, and they are specialized for various motor tasks with different physical object contact situations. Insufficient strength during aging constitutes a key component of sarcopenia and is associated with subsequent disability and mortality. The simplest and very valid test for assessing general strength is the handgrip test, and the need for international standards for grip strength seems very essential. The study aimed to set normative data for different handgrip strength dimensions in an international healthy adult community. Methods. The maximal muscle force and maximal explosive muscle force for dominant and non-dominant hand were examined across 838 subjects from 11 countries. The result values were compared with the internationally published findings for external validation. Results. The mean value for both hands maximal strength in an adult male was 997 ± 176 N for the absolute and 11.78 ± 1.95 N/kg for the relative measure; in females, the respective values equalled 550 ± 110 N and 8.49 ± 1.79 N/kg. The mean value for maximal explosive strength in an adult male was 6473 ± 1420 N/s for the absolute and 76.47 ± 16.22 N/s/kg for the relative measure; in adult females, the respective values equalled 3506 ± 915 N/s and 54.13 ± 14.38 N/s/kg. Conclusions. The normative reference values provided in this study may serve as an international guide for interpreting maximal and explosive handgrip strength measurements obtained from healthy adult individuals of both genders.

Purpose. smartphone is one of the essential tools but may be inappropriate during locomotion or transportation owing to cognitive distractions. The study aimed to investigate the main effects of smartphone tasks, obstacle conditions, and their interaction on the spatiotemporal gait and centre of mass (cOM) variables among healthy young adults. Methods. The study used a single group with repeated measures design. Overall, 20 participants completed 4 smartphone tasks (no task, texting, calling, and watching), combined with 2 conditions of obstacle confrontation (with and without). spatiotemporal gait (step length, step time, cadence, and gait speed) and cOM variables during gait (excursion and velocity in mediolateral and vertical directions) were collected. Results. significant effects of smartphone tasks and obstacle conditions were found, while no interaction effect between smartphone tasks and obstacle was found. There were alterations of the spatiotemporal gait and cOM variables during walking, both with and without obstacle. The obstacle condition significantly influenced the different tasks of mobile perturbation, all spatiotemporal gait and cOM variables, except for the cOM mediolateral velocity. Conclusions. confronting smartphone tasks and obstacle conditions concurrently challenges young adults to adjust their movement and balance control systems to perform the tasks successfully.

Purpose. In futsal, the goal is the most important situation that can lead the teams to victory. the understanding of when they are scored can help adopting effective strategies, increasing the chances of victory. this study aimed to compare 2 models for analysing goals scored in futsal as a function of time. Methods. Overall, 1122 goals were analysed in 194 matches of the 2018 Brazilian Futsal League, male adult category. the playing time was divided into four 10-minute periods (conventional model) and eight 5-minute periods (alternative model). the goal occurrence was compared with mixed models of repeated measures, and the fit of models by Akaike information criterion (AIC) and Bayesian information criterion (BIC). Results. Both models were statistically significant ( p < 0.001), indicating that the means of goals were different depending on the periods. the conventional model showed that the mean of goals was higher in the final 10 minutes ( p < 0.001); the alternative model implied that from the seventh to the eighth period the mean of goals increased by 39.1% (95% CI: 0.27–0.64, p < 0.001). In addition, the 5-minute model revealed a better fit than the 10-minute model in accordance with AIC and BIC. Conclusions. this finding suggests that more reliable models are useful for better understanding of how the frequency of crucial events, such as goals, changes in the course of a match. We provide information for the coaching staff to strategi-cally think about the best situations for their teams to succeed in competitive matches.

Purpose. the study aim was: (a) to investigate the relationship between triceps brachii muscle architecture and upper-body isometric rate of force development (rFD), isometric peak force (IPF), and maximum strength (one-repetition maximum, 1-rM) in bench press and (b) to explore whether triceps brachii architecture might determine rFD, IPF, and 1-rM strength in stronger and weaker participants. Methods. the study involved 21 males (age: 22.6 ± 4.7 years, weight: 76.6 ± 10.2 kg, height: 1.79 ± 0.07 m) with 3.4 ± 2.1 years of experience in resistance training. they were divided into a strong and weak group depending on their relative 1-rM strength in bench press. Measurements included triceps brachii muscle architecture, upper-body isometric rFD, IPF, and 1-rM strength in bench press. Results. Moderate to large correlations were found for triceps brachii thickness and fascicle angle with upper-body rFD ( r : 0.379–0.627), IPF ( r : 0.582 and 0.564, respectively), and 1-rM strength in bench press ( r : 0.530 and 0.412, respectively). Maximum strength in bench press was largely correlated with IPF ( r = 0.816); moderate to very large correlations were observed with rFD ( r : 0.499–0.725). the strong group presented significantly higher 1-rM relative strength, rFD, and IPF ( p < 0.05) than the weak group, but no significant between-group difference was found for triceps brachii architecture ( p > 0.05). Conclusions. triceps brachii architecture correlates with 1-rM strength, upper-body rFD, and IPF in trained participants. However, triceps brachii architecture may not distinguish upper-body strength and rFD between stronger and weaker male participants.
