Composite stretchable conducting wires Think how useful a electronic “skin” could be. For example you place it over an aircraft fuselage or body to create network of sensors, processors, energy stores, artificial muscles. But is difficult make interconnects and strain sensors that can stretch such surfaces. Liu et al. created superelastic fibers by depositing carbon nanotube sheets onto prestretched rubber core (see the Perspective Ghosh). The nanotubes buckled on relaxation core, but...
The purpose of this study was to characterise Brazilian teams' coverage area and spread on the pitch while attacking defending analyse organisation in tackle shot goal situations. We obtained trajectories 223 players eight games with a tracking method. Team defined as convex hull formed by players' positions. Frobenius norm distance-between-player matrix. calculated over time situations shots (n = 233) tackles 1897). While attacked, (median +/- confidence interval) ranged from 322.9 0.8...
Abstract The purpose of this study was to explore football game-related statistics during a competition, using principal component and cluster analyses determine if it is possible distinguish the winning teams from drawing losing ones. We collected group phase matches 2006 World Cup organised them into matrix. components covariance matrix were calculated. scores first second used represent new data, analysis applied separate elements in two groups (G1 G2). To analyse degree separation...
Abstract The purposes of this study were to characterise the total space covered and distances between players within teams over ten Brazilian First Division Championship matches. Filmed recordings, combined with a tracking system, used obtain trajectories (n = 277), before after half-time. team surface area (the convex hull formed by positions players) spread Frobenius norm distance-between-player matrix) calculated as functions time. A Fast Fourier Transform (FFT) was applied each time...
The purpose of this study was to measure and characterise the distances covered by Brazilian professional futsal players. trajectories 93 players during five matches were obtained using an automatic tracking method. analysed for different game conditions: over entire times when ball out play in separately. When considered, results showed that there a reduction total distance per minute from first [median ± IQR (interquartile range): 97.9 16.2 m/min] second half (median = 90.3 m/min; 12.0),...
The purposes of this study were to investigate sprints and characterize repeated-sprint sequences (RS) performed by athletes during professional futsal matches. We analyzed 97 players 5 official matches using the DVideo automatic tracking system. first second halves according playing position, RS categorized number time between them. results showed an increase (F[1, 2520] = 3.96; P .046) in sprint duration from (mean 3.1 ± 1.3) half 3.2 1.2). However, no differences found for other variables...
The purpose of this study was to analyse the physical and technical performances professional tennis players during official matches. trajectories eight were obtained matches, using an automatic tracking method. distances covered analysed for first second sets. athletes (mean ± standard deviation) a total 1702.4 448.2 m in set, 1457.6 678.1 set 3160.0 880.1 entire match. No differences found between sets variables (lateral forward displacements, distance per rally, game percentage time spent...
Purpose This study aimed to investigate the effects of match location, quality opposition, outcome, and playing position on internal load (IL), external (EL), interpersonal interactions in professional soccer players. Also, relationships between parameters were measured. Methods Fourteen matches from 16 Brazilian players analysed. IL was obtained through rating perceived exertion. EL quantified with Global Positioning System (e.g., high-intensity running [HIR]). Interpersonal measured by...
While chemotherapy treatment can be lifesaving, it also has adverse effects that negatively impact the quality of life. To investigate doxorubicin on body weight loss, strength and muscle mass physical function impairments, all key markers cachexia, sarcopenia, frailty. Seventeen C57/BL/6 mice were allocated into groups. 1) Control (n = 7): exposed to intraperitoneal (i.p.) injections saline solution. 2) Dox 10): cycles (total dose 18 mg/kg divided over 15 days). The loss decreased food...
Creatine has demosntrated protective effects against muscle dysfunction, but its potential protection doxorubicin-induced cardio and skeletal toxicity remains poorly understood. We aimed to investigate the of creatine supplementation myotoxicity. This study analyzed twenty male C57BL/6J mice, divided into three groups: Control (C; n = 6), Dox (n 7) which received weekly doxorubicin injections (16 mg/kg i.p. in 20 days) DoxCr with both (4%). Doxorubicin administration induced atrophy extensor...
Background/Objectives: Dribbling is a fundamental skill in soccer, but assessing the performance of youth players this complicated by confounded effects age and physical development. In study, our aim was to quantify interactive age, height, mass on dribbling 180 between 10 21 years old from an elite Brazilian junior academy. Methods: For each player, we quantified their sprinting speed along four different paths with varying curvature, ability perform specific, directed drills using one or...
Tracking systems in sports aim to record athlete’s position as a function of time. From these data, information on physical, tactical and technical performance is obtained assists coaches players decision-making during the training competition routine. The implementation, feasibility, quality data generated by tracking depend conditions each sporting environment their requirements. This narrative review addresses fundamentals main systems, including algorithms based computer vision...
The purpose of this study was to investigate the coordination between teams spread during football matches using cross-correlation and vector coding techniques. Using a video-based tracking system, we obtained trajectories 257 players 10 matches. Team calculated as functions time. For general description, signals. Vector used identify patterns offensive sequences that ended in shots on goal or defensive tackles. Cross-correlation showed opponent have tendency present in-phase coordination,...

Osteoarthritis (OA) is a chronic degenerative disease that commonly affects the knee joints. Individuals older than 65 years of age with OA have greater risk falls. However, there has been limited examination parameters postural sway (increased time, speed, and area [center pressure{CoP}]), knee.The primary objective this study was to determine whether CoP variables discriminate between patients matched healthy volunteers, correlate Activities-Specific Balance Confidence Scale (ABC) Falls...
The purpose of this study was two-step: (1) classify ball possession (BP) according to the duration and number passes (2) identify which tactical variables most discriminate different BP. We obtained 527 BPs from four official matches Brazilian Soccer Championship 2016. Forty-one "notational", "space occupation", "displacement synchronization" predictor were used. classified into three groups: short (11.07 ± 4.49 s, 1.93 0.99 passes), medium (26.83 7.33 5.41 1.84 long (55.50 14.97 12.11 4.61...
Abstract The purpose of this study was to analyse players’ positional variability during the 2012 UEFA European Championship by applying principal component analysis (PCA) data gathered from heat maps posted on website. We analysed teams that reached finals and semi-finals competition. 2D coordinates each match were obtained an image-processing algorithm maps. With all for match, we applied PCA identify directions greatest variability. Then, two orthogonal segments centred player’s mean...
Muscle wasting has been emerging as one of the principal components cancer cachexia, leading to progressive impairment work capacity. Despite early stages melanomas rarely promotes weight loss, appearance metastatic and/or solid tumor melanoma can leads cachexia development. Here, we investigated B16F10 tumor-induced and its contribution muscle strength locomotor-like activity impairment. C57BL/6 mice were subcutaneously injected with 5 x 104 cells or PBS a Sham negative control. Tumor...
The aim was to investigate the influence of a carbohydrate (CHO) mouth rinse on vastus lateralis (VL) and rectus femoris (RF) electromyographic activity (EMG) time exhaustion (TE) during moderate (MIE) high-intensity cycling exercise (HIE).
