  The aims of the present study were to analyse the relationship between the physical performance and the match load in cerebral palsy (CP) football players, and to analyse the possible impact of the Spanish League format (playing two matches on two consecutive days) on the players’ match load. Data for a Spanish CP football team (n=10; age: 31.0 ± 8.9 years; weight: 66.1 ± 8.6 kg; height: 172.2 ± 7.8 cm; BMI: 22.5 ± 2.9 kg·m-2) included anthropometric (weight, height and BMI), physical performance (CMJ, 5, 10 y 20-m sprint y MAT) and match load variables (distance covered, accelerations and decelerations, heart rate, speed and player load) from two official matches. The players’ physical performance, but not their anthropometrical measurements, correlated to the match load variables (r = 0.76–0.95; p = 0.04–0.01), except for accelerations, decelerations and heart rate-related variables (p > .05). Players’ match load data were not statistically different between matches. The results suggest that players’ physical performance influences the match load variables, and these players’ load variables in competition do not seem to be affected by the fact of playing two matches on two consecutive days. The way in which the players’ physical performance and fatigue may affect the match load variables needs more research in CP football.  Resumen. Los objetivos de este estudio fueron analizar la relación entre el rendimiento físico y la carga de partido en jugadores de fútbol con parálisis cerebral (PC), y analizar la posible influencia del formato de la Liga Española (en la que se juegan dos partidos en días consecutivos) en la carga de partido. Los datos obtenidos de un equipo español de fútbol PC (n=10; edad: 31.0 ± 8.9 años; peso: 66.1 ± 8.6 kg; altura: 172.2 ± 7.8 cm; IMC: 22.5 ± 2.9 kg·m-2) incluyó variables antropométricas (peso, altura e IMC), de rendimiento físico (CMJ, 5, 10 y 20-m sprint y MAT) y variables de carga de partido (distancia recorrida, aceleraciones y deceleraciones, frecuencia cardiaca, velocidad y carga del jugador) en dos partidos oficiales. El rendimiento físico de los jugadores, pero no las variables antropométricas correlacionaron con la carga de partido (r = 0.76–0.95; p = 0.04–0.01), excepto para las aceleraciones, deceleraciones y variables relacionadas con la frecuencia cardiaca (p > .05). Los datos acerca de la carga de partido no fueron significativamente distintos entre partidos. Los resultados sugieren que el rendimiento físico de los jugadores de fútbol PC influyen en la carga en competición y esas variables de carga de partido no parecen estar afectadas por el hecho de jugar dos partidos en días consecutivos. La manera en la que el rendimiento físico de los jugadores y la fatiga puede afectar en la carga de partido necesita mayor investigación en fútbol PC.

  Objetivo: el objetivo de este estudio fue: i) Caracterizar el perfil del rendimiento físico de los futbolistas con parálisis cerebral (PC) de la selección Chilena de fútbol 7 acorde a su clasificación deportiva (CD) y posición de juego; ii) Analizar la relación entre las variables de rendimiento físico con la CD. Método: Participaron 19 jugadores varones con PC pertenecientes a la selección Chilena de fútbol 7 agrupados según CD (FT1, FT2, FT3) y posición de juego. Se realizaron mediciones de agilidad (AG), capacidad de realizar sprint repetido (RSA), distancia recorrida en la prueba Yo-Yo (D), capacidad de salto con las pruebas Squat Jump (SJ) y Countermovement Jump (CMJ). Resultados: Se encontraron diferencias significativas de acuerdo a las CD donde los jugadores FT3 lograron un mayor rendimiento en las pruebas de AG y D comparado con FT2 y FT1, no así para RSA donde solo fue superior a FT1. Mediocampistas lograron un mayor rendimiento con un tamaño del efecto grande en todas las variables en comparación a las posiciones de defensa y delantero. Se observaron relaciones fuertes y muy fuertes entre todas las variables de rendimiento físico, así también para las relaciones con la CD a excepción de SJ y CMJ. Conclusión: Se deben considerar las características específicas de cada CD de los jugadores con PC en conjunto con la posición de juego y la táctica del equipo en sí misma, conjugando una serie de factores que busquen lograr los más altos niveles de rendimiento físico y deportivo. Abstract. Objective: The aims of this study were: i) Characterize the physical performance profile of cerebral palsy (CP) football players of the Chilean national team of football 7 a-Side according to the sport classification (SC) and playing position; ii) Analyze the relationship between physical performance variables and the SC. Method: 19 male football players with CP belonging to the Chilean national team of football 7 a-Side participated and were grouped according to SC (FT2; FT2; FT3) and playing position. Measurements of Agility (AG), repeated sprint ability (RSA), the covered distance in the Yo-Yo test (D), jump ability in Squat Jump (SJ), and Countermovement Jump (CMJ) test were made. Results: Significant differences were found according to SC, where FT3 players achieved higher performance in AG and D tests compared to FT2 and FT1, not for RSA, which was only higher than FT1. Midfielder achieved a higher performance with a large effect size in all variables compared with defender and forward positions. Strong and very strong relationships were observed between all the physical performance variables, as well as for relationships with SC except for SJ and CMJ. Conclusion: The specific characteristics of each SC of CP players must be considered in conjunction with the playing position and the team's tactics, combining a series of factors that seek to achieve the highest levels of physical and sports performance.

The notion of comfort with respect to rides, such as roller coasters, is typically addressed from the perspective of a physical ride, where the convenience of transportation is redefined to minimize risk and maximize thrill. As a popular form of entertainment, roller coasters sit at the nexus of rides and games, providing a suitable environment to measure both mental and physical experiences of rider comfort. In this paper, the way risk and comfort affect such experiences is investigated, and the connection between play comfort and ride comfort is explored. A roller coaster ride simulation is adopted as the target environment for this research, which combines the feeling of being thrill and comfort simultaneously. At the same time, this paper also expands research on roller coaster rides while bridging the rides and games via the analogy of the law of physics, a concept currently known as motion in mind. This study’s contribution involves a roller coaster ride model, which provides an extended understanding of the relationship between physical performance and the mental experience relative to the concept of motion in mind while establishing critical criteria for a comfortable experience of both the ride and play.

The Relationship

Background: Body structure constitutes a kinetic chain with thoracolumbar fascia and this chain may induce a relationship between scapular and spinal stabilizers. Amputee soccer players use crutches during the game and, considering that the crutch use may also activate different muscle groups, the possibility of the relationship between scapular and spinal stabilizers becomes important for organizing training programs. The aim of this study is to determine the relationship between scapular endurance and core endurance in elite amputee players. Material and methods: Fifteen male amputee national football team players took part in the study. The players’ scapular endurance was evaluated by a dynamometer, and the modified side bridge test was used to evaluate core endurance. Results: The relationship between scapular and core endurance was investigated via the Linear Regression Model. The analysis revealed a positive association between scapular endurance and core endurance (B: 0.501, β: 0.561, p: 0.029). Conclusions: This study shows the relationship between scapular and core endurance in amputee football players. Given the assumptions about scapular and core endurance weakness, including scapular muscle exercises along with core exercises in the training programs might be useful for improving performance.

This study aims to compare the performance values of U-16 development league football players. The research was carried out according to the experimental research model. A total of 25 football players of a super league football team (age: 16, height: 170,36±7,31cm, weight: 56,89±8,88kg), all competing in the U-16 elite development league, participated voluntarily. The players wear Polar watches on the grass football field; Yo-Yo Intermittent Recovery Level 1 test was applied and aerobic endurance levels, maximal heart rate, and heart rate recovery times were measured. Tests and measurements were applied 1 week before the start of the league. After the first test, the competition period general training program was applied for 9 weeks, 4 days a week, and after that, the same tests and measurements were carried out again. After a 9-week competition training program, there were statistically significant differences in aerobic endurance levels and heart rate recovery times at the 1st minute (p<0.01), no statistically significant differences were found in maximal heart rate and heart rate recovery times at the 2nd minute (p>0.01). In conclusion, it can be said that the 9-week training program applied during the competition period is effective on the aerobic endurance level and heart rate recovery time in the 1st minute. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0893/a.php" alt="Hit counter" /></p>

AbstractWe aimed to characterize cardiac-autonomic responses to a 13-day preseason camp in the heat among an American college football team. Players were categorized as linemen (n=10) and non-linemen (n=18). RHR, natural logarithm of the root-mean square of successive differences multiplied by twenty (LnRMSSD), and subjective wellbeing (LnWellness) were acquired daily. Effect sizes±90% confidence interval showed that for linemen, LnRMSSD decreased (moderate) on day 2 (71.2±10.4) and increased (moderate) on day 12 (87.1±11.2) relative to day 1 (77.9±11.2) while RHR decreased (small–moderate) on days 6, 7, and 12 (67.7±9.3–70.4±5.5 b∙min-1) relative to day 1 (77.1±10.1 b∙min-1). For non-linemen, LnRMSSD increased (small–large) on days 3–5, 7, 12, and 13 (83.4±6.8–87.6±8.5) relative to day 1 (80.0±6.5) while RHR decreased (small–large) on days 3–9, 12, and 13 (62.1±5.2–67.9±8.1 b∙min-1) relative to day 1 (70.8±6.2 b∙min-1). Decrements in LnWellness were observed on days 4–10 and 13 for linemen (moderate) and on days 6–9, 12, and 13 for non-linemen (small–moderate). Despite reductions in LnWellness, cardiac-autonomic parameters demonstrated responses consistent with heat-acclimation, which possibly attenuated fatigue-related decrements.

The Relationship

This study aimed to describe and determine relationships between repeated sprint and change of direction (COD) abilities in football players with cerebral palsy according to four sport classes (FT5 to FT8). Seventeen male football players with cerebral palsy took part in this study (23.0±4.7 years, 65.9±9.5 kg, 168.8±5.9 cm). The repeated sprint ability (6×40-m sprints with a 20-second recovery) was evaluated to determine the best sprint time, mean sprint time, and percentage of sprint decrement. The difference in lactate concentration was determined using blood samples taken three minutes before and after testing. The Illinois Agility Test (IAT) was also used to assess players’ change of direction ability. The FT8 players had better performance (p&lt;.01) in the best sprint time, mean sprint time and in the IAT scores compared to the players of the sport classes FT5/6. Players of the sport class FT7 also reached higher performance in the IAT compared to the players of the sport classes FT5/6 (p&lt;.05). A significant correlation was found between the best sprint time and mean sprint time (r=.94, p&lt;.01), the best sprint time and the IAT (r=.62, p&lt;.01), and between the best sprint time and the difference in lactate concentration (r=-.51, p&lt;.05). The relationships between repeated sprint and change of direction abilities demonstrate the performance profile of para-footballers with cerebral palsy in those variables according to their sport classes, exhibiting lower performance than the values reported for regular football players.

The Relationship

In this article, we report on a multimethod qualitative study designed to explore the emotional experiences of students in the classroom setting. The purpose of the study was threefold: (1) to explore the correspondence among nonverbal expressions, subjective feelings, and physiological reactivity (heart rate changes) of students’ emotions in the classroom; (2) to examine the relationship between students’ emotions and their competence and value appraisals; and (3) to determine whether task difficulty matters in emotional experiences. We used multiple methods (nonverbal coding scheme, video stimulated recall interview, and heart rate monitoring) to acquire data on emotional experiences of six grade 7 students. Concurrent correspondence analyses of the emotional indices revealed that coherence between emotional response systems, although apparent, is not conclusive. The relationship between appraisals and emotions was evident, but the effect of task difficulty appears to be minimal.
