Despite its growing popularity, few studies have investigated specific physiological demands for elite female futsal. The aim of this study was to determine aerobic fitness in elite female futsal players using laboratory and field testing. Fourteen female futsal players from the Venezuelan National team (age =21.2±4.0 years; body mass =58.6±5.6 kg; height =161±5.0 cm) performed a progressive maximal treadmill test under laboratory conditions. Players also performed a progressive intermittent futsal-specific field test for endurance, the Futsal Intermittent Endurance Test (FIET), until volitional fatigue. Outcome variables were exercise heart rate (HR), VO2, post-exercise blood lactate concentrations ([La]b) and running speeds (km · h-1). During the treadmill test, VO2max, maximal aerobic speed (MAS), HR and peak [La]b were 45.3±5.6 ml · kg-1 · min-1, 12.5±1.77 km · h-1, 197±8 beats · min-1 and 11.3±1.4 mmol · l-1, respectively. The FIET total distance, peak running velocity, peak HR and [La]b were 1125.0±121.0 m, 15.2±0.5 km · h-1, 199±8 beats · min-1 and 12.5±2.2 mmol · l-1, respectively. The FIET distance and peak speed were strongly associated (r= 0.85-87, p < 0.0001) with VO2max and MAS, respectively. Peak HR and [La]b were not significantly different between tests. Elite female futsal players possess moderate aerobic fitness. Furthermore, the FIET can be considered as a valid field test to determine aerobic fitness in elite level female futsal players.

Background and Objectives: In modern soccer, players frequently perform curved sprinting (CS) actions that combine speed, agility, and neuromuscular control, highlighting the importance of assessing CS performance in youth athletes. This study aimed to investigate age-related differences in CS performance and its relationship with key components of physical fitness—including aerobic capacity, vertical jump height, and agility-based field tests—in U14 and U16 male soccer players. Materials and Methods: A total of 76 registered players participated, evenly divided between the two age groups. Statistical analyses included t-tests, correlation, and regression modeling to determine key predictors of curve-sprint performance. Results: U16 players showed significant between-group differences, with faster CS times on both the good and weak sides (p < 0.001, d = 0.93–1.08), as well as superior performance in the countermovement jump (p < 0.001, d = 1.12), Illinois Agility Test (p < 0.01, d = 0.70), and 5-0-5 change-of-direction (COD) test (p < 0.01, d = 0.74). Significant negative correlations were found between CMJ height and CS times (r = –0.40 to –0.73), indicating that greater explosive power was associated with better CS performance. Moderate to very strong positive correlations were observed between CS and agility measures (r = 0.43 to 0.79), particularly in the U16 group, whereas VO₂max showed no meaningful relationship with CS performance (r = –0.16 to –0.30, p > 0.05). Conclusions: These results suggest that CS may serve as an indicator of neuromuscular power and agility, both of which improve with age. From a practical perspective, regular curve-sprint assessments and multidirectional drills may support talent development by helping coaches monitor neuromuscular efficiency and movement coordination in young players.

Among the many factors that can affect men’s soccer performance, technical and tactical actions can obscure relevant game data, even affecting specialists in both the programming and design of training tasks. We aimed to evaluate the technical and physical load variables of different positions in U18 semi-professional soccer players and observe the differences between the first and second halves during 10 matches of the 2021/2022 Spanish Football U18 National League Championship. A total of 246 match records (10 matches) were collected from the 2021/2022 Spanish Football U18 National League Championship. Two teams participated, with a total of 49 athletes. Our study’s results indicate that, concerning technical performance, no significant differences between halves were found for goalkeepers, wingers, and forwards. However, significant declines were observed in the number of ball contacts, different actions per time, and possessions per time among central defenders, lateral defenders, and central midfielders. Regarding the observed physical load demands, it was noted that in outfield players, there was a significant decline in total distances covered at different speed thresholds, as well as a decrease in the number and distance of acceleration measures, most of which were lower in the second halves compared to the first, irrespective of playing positions. This study contributes to enhancing our understanding of the multifaceted dynamics of soccer performance and provides valuable insights for coaches, players, and researchers aiming to optimize player performance.

Los efectos de los patrones funcionales surgidos durante la adquisición bimanual de los movimientos de los dedos tocando flauta dulce bajo restricciones informacionales auditivas y visuales en la tarea instrumental, pueden contribuir a mejorar variables importantes relacionadas con la sincronización, precisión de la ejecución, pérdida de ritmo, entre otras variables. 147 alumnos de 3º curso de educación secundaria se sometieron a 5 variaciones de un programa de aprendizaje de flauta durante 12 sesiones de práctica. Los resultados muestran una resistencia al deterioro frente al resto de grupos en la prueba de retención, en variables importantes instrumentales como es el error de nota al grupo al que se aplicaron restricciones totales (GE1), aunque uno de los grupos sometido a restricciones parciales (GE3) también obtuvo mejoras estadísticamente significativas respecto al resto de grupos en otra variable importante como es la sincronización.
