Reception and performance in high level male volleyball: A relational study

[EN] The aim of this study was to know the association of the reception zone on the performance of the reception of the high-performance male volleyball teams, considering the impact of rotation. The sample consist of 4223 KI sequences, belonging to 29 men's matches of world national teams of the highest level played between 2012 and 2016. The 3 main variables were: the rotation of the team in reception; the reception area; and the reception performance. For data analysis, Pearson's Chi-square analysis has been used to determine the influence of rotation in the reception area, and ordinal regression models to determine the influence of the reception area and the interaction of rotation on the reception performance. The level of significance was set at p = .05. Results showed differences in the distribution of the serve depending on the team's rotation (p < .001; V = 0.123). Significant relationships and interactions were also found between the rotation of the equipment and the reception area, that allow us to understand the greater or lesser probability of achieving a better reception performance (p < .001). In conclusion, the reception area is associated with the rotation of the team, which seems to be related to tactical decisions during the serve of the rival team. Furthermore, the reception performance is different depending on the rotation of the equipment, the reception area, and the interaction between both variables.S

Emotional Intelligence of Undergraduate Athletes: The Role of Sports Experience.

Sport is an emotional experience. Studies have shown that high emotional intelligence (EI) is associated with better sports performance, though different aspects of sports experience and their relationship with EI are still unclear. This study examined the possible relationships between sports experience and EI dimensions of undergraduate athletes. Likewise, according to the differences described in the literature between men and women, the secondary aim was to identify the possible relationship between EI and sports experience in both subgroups. A total of 1784 [712 men (39.9%), 1072 women (60.1%); mean age = 21.3 years, SD = 4.2)] undergraduate athletes completed the Trait Meta Mood Scale and a sports experience questionnaire. Comparisons between groups were performed using Mann–Whitney-U and H-Kruskal–Wallis tests and correlations between variables were analyzed using Spearman correlation. We found that the number of different sports practiced and the number of years practicing sports were positively associated with emotional repair (ER). However, the number of years practicing sports was negatively associated with emotional attention (EA). Male athletes who trained more and had a higher competitive level were more likely to show higher ER. In any case, it is necessary to take into account that all the associations were weak. Our study suggested that athletes tend to attend to and value their feelings and use positive thinking to repair their negative moods.post-print196 K

Transición recepción-ataque en voleibol: análisis de la efectividad del remate

[ES] El objeto de este estudio fue valorar la efectividad del remate del receptor delantero en función de su participación en la transición recepción-ataque y de la rotación del equipo, así como en función de la interacción entre ambas. La muestra se extrajo de 29 partidos jugados entre 2012 y 2016 por selecciones nacionales masculinas de máximo nivel mundial. Las variables estudiadas fueron: la rotación de equipo receptor, la existencia de transición recepción-ataque y el rendimiento del remate. En el análisis de datos, se describieron la media, la desviación típica y la efectividad; además de emplear ji al cuadrado de Pearson y modelos de regresiones ordinales para determinar la influencia de la transición, la rotación del equipo y la posición del colocador sobre el rendimiento del remate. El nivel de significación fue establecido en p = .05. Los resultados mostraron un mejor rendimiento en remate del receptor delantero cuando no realizó transición y el colocador se encontró en posición zaguera, especialmente en las rotaciones RT1 y RT5. También se encontró un mejor rendimiento del remate cuando se realizó la transición con colocador delantero, en relación con colocador zaguero. El peor rendimiento en remate se produjo cuando existió transición y el equipo se encontraba en RT6. Como conclusión, el rendimiento del remate del receptor delantero se ve afectado por la interacción entre la transición y la rotación del equipo en K1; ya sea estudiando las rotaciones de manera individual, o de manera integrada en función de la posición del colocador.S

Rendimiento del remate en K1: Influencia de la rotación y la zona de recepción en equipos de voleibol de alto nivel masculino

El objetivo de este estudio, fue investigar la asociación de la zona de recepción con el rendimiento del remate considerando el impacto de la rotación, en equipos de voleibol masculino de alto nivel. Fueron analizados 29 partidos de selecciones internacionales masculinas de máximo nivel, obteniendo una muestra de 3689 remates en la fase de KI. Las variables analizadas fueron: la rotación del equipo en recepción, la zona de recepción y el rendimiento del remate. Se emplearon modelos de regresión ordinales para determinar la influencia de la zona de recepción y la interacción de la rotación en el rendimiento del remate. Los resultados mostraron interacciones significativas entre la rotación y la zona de recepción, que permiten entender la mayor o menor probabilidad de conseguir un mejor rendimiento en remate (p<0.001) en algunas de las rotaciones. En conclusión, el rendimiento del remate es diferente en función de la interacción de la rotación del equipo y de la zona de recepción, lo que podría asociarse con decisiones tácticas en la ejecución del saque.The purpose of this study was to investigate the association between the reception zone and the spiking performance in each of the game rotations in top level men's volleyball teams. The sample consisted of 29 men´s matches of final phases in Olympic Games, World League and World Cup between 2012 and 2016, obtaining a sample of 3,689 spikes in the K1 phase. The variables analyzed were: the rotation of the reception team, the reception area and the spike performance. Ordinal regression models were used to determine the influence of the receiving zone and the interaction of rotation on spike performance. The results show significant interaction between the rotation and the reception area on spike performance (X²₄₆ = 127.885; p <.001; r2 = .036), which allow us to understand the greater or lesser probability of achieving a better spike performance in some of the rotations. In conclusion, the performance of the spike varies depending on the interaction of the rotation of the team and the reception area, but this relation in global level, only explain 3.6% of the variance of the spike. The analysis of the situations in which significance has been found could be associated with strategic decisions in the execution of the serve and the training of the K1

Explanatory Capacity of Postural Control and Physical Fitness in Cognitive Impairment and Support Needs among Individuals with Intellectual Disabilities—A Cross-Sectional Pilot Study

[EN] Postural control is a skill associated with most motor activities and is essential for the performance of activities of daily living. People with intellectual disabilities (ID) present postural control deficits that can be attributed to several causes. The aim of this study was to determine whether postural control and physical fitness could explain the cognitive impairment and support needs in this population. A cross-sectional pilot study was conducted with 18 people with ID. Data collection was based on assessments for postural control (Mini BESTest and Berg Balance Scale) and physical fitness (Senior Fitness Test). The data were analyzed using linear regression models. Anticipatory postural adjustments were associated with support needs, explaining up to 45% of these. Consecutive postural adjustments and upper limb strength were less significantly associated with support needs. However, none of the variables used explained cognitive impairment in ID. Knowledge of the relationships and behavior of the different measurement tools is essential for the development of appropriate interventions in this population.S

Physical Activity and Mental Health in Undergraduate Students

[EN] Most research support positive relationships between physical activity and mental health. However, possible moderating variables of these relationships have also been identified, such as age, gender, level of physical activity, and the scope of physical activity. This study aimed to analyze the relationships between physical activity and mental health levels in undergraduate students, assessing whether these associations can change depending on the level of physical activity (low, medium, or high) and the setting (occupational, commuting, or leisure time physical activity) in which it was performed. A descriptive and cross-sectional study was conducted. The sample comprised 847 undergraduate students. Physical activity and mental health were measured by the Global Physical Activity Questionnaire (GPAQv2) and the General Health Questionnaire (GHQ-12). We found relationships between students’ physical activity level and their mental health status. The higher the total physical activity, the better their mental health scores. High levels of commuting and leisure time physical activity is also associated with better mental health, while only moderate levels of occupational physical activity are associated with better mental health status. Regarding the possible associations between physical activity and vulnerability to mental health problems, with the fully adjusted regression model, leisure time and occupational physical activity remain protective of a poor state of mental health. Leisure time physical activity, performed at a high level, and moderate occupational physical activity seems to be the best combination of physical activity to reduce students’ vulnerability to potential mental health problems.SIUniversidad Francisco de Vitori

Adherence and long-term outcomes of growth hormone therapy with easypod™ in pediatric subjects: Spanish ECOS study

E-health; Easypod; Electronic deviceE-salut; Easypod; Dispositiu electrònicE-salud; Easypod; Dispositivo electrónicoBackground: Non-adherence to r-hGH treatments occurs in a variable percentage of subjects. One problem found when evaluating adherence is the great variability in methods of detection and definitions utilized in studies. This study assessed the level of adherence in subjects receiving r-hGH with the easypod™ electronic device. Methods: National, multicenter, prospective and observational study involving 238 subjects (144 with GH deficiency (GHD), and 86 with small for gestational age (SGA), 8 with Turner Syndrome), who received r-hGH with easypod™ for at least 3 months before inclusion. The follow-up period was 4 years. Results: Overall adherence was 94.5%; 97.5% after 6 months, 95.3% after 1 year, 93.7% after 2, 94.4% after 3 and 95.5% after 4 years of treatment. No differences in adherence were observed between prepubertal and pubertal groups and GHD and SGA groups. Change in height after 1 and 2 years, change in height SDS after 1 and 2 years, HV after 1 year, HV SDS after at 1 and 4 years, change in BMI after 1 year and change in BMI SDS at 1 and 2 years showed significant correlation with adherence. No significant differences in adherence according to IGF-I levels were found in follow-up visits or between groups. Conclusions: The easypod™ electronic device, apart from being a precise and objective measure of adherence to r-hGH treatment, allows high compliance rates to be achieved over long periods of time. Adherence significantly impacts growth outcomes associated with r-hGH treatmentThis study was funded by Merck, S.L., Madrid, Spain

Tensiomyography, sonoelastography, and mechanosensitivity differences between active, latent, and control low back myofascial trigger points: a cross-sectional study

7 p.The myofascial pain syndrome (MPS) is considered the most common musculoskeletal condition. The lumbopelvic pain (LPP) is established as one of the most prevalent musculoskeletal disorders. Nevertheless, previous research has not yet studied the contractibility changes by tensiomyography between myofascial trigger point (MTrP) types and normal tissue. Therefore, the aim of this study was to determine the tensiomyography, sonoelastography, and pressure pain threshold (PPT) differences between the palpation area of active and latent MTrPs with regards to control points in the lumbar erector spinae muscles of subjects with LPP. A cross-sectional descriptive study was performed. A convenience sample of 60 points (20 active MTrPs, 20 latent MTrPs, and 20 control points) was registered bilaterally in the lumbar erector spinae muscles from subjects with nonspecific LPP. The palpation order of active MTrPs, latent MTrPs, or control points was randomized for each side. The outcome assessors were blinded to the order or point type. The outcome measurements order for each point was sonoelastography manual strain index, tensiomyography, and PPT, separated by 15 minutes. Five contractile objective parameters were: maximal radial displacement (Dm), contraction time (Tc), sustain time (Ts), delay time (Td), and half-relaxation time (Tr). Tensiomyography parameters did not show any statistically significant difference (P> 0.05) between active MTrPs, latent MTrPs, and control points. Nevertheless, PPT and sonoelastography showed statistically significant differences (P< 0.05) between all point types, except for active and latent MTrPs PPT comparison (P= 0.091). Regarding the active MTrPs, a moderate positive correlation was observed between PPT and Dm (P= 0.047; tB = 0.450). Considering the control points, a moderate positive correlation was shown between sonoelastography and Td (P= 0.044; tB = 0.328). The tensiomyography contractile properties did not seem to show differences, while the sonoelastography and mechanosensitivity presented a higher stiffness and a lower PPT, respectively, between the palpation area of active and latent MTrPs with regards to control points in the lumbar erector spinae muscles of subjects with LPP. Considering the correlations, further research is needed regarding the muscle contractile properties modifications under MPS treatments, especially Dm in active MTrPs and Td in normal sites.S

Monitoring of the flexor-extensor musculature of the knee in high-performance female volleyball players

[ES] El propósito del estudio fue describir, a través de TMG, los cambios producidos en las características mecánicas de la musculatura responsable de la flexo extensión de la articulación de la rodilla: antes y después de un periodo de entrenamiento, en jugadoras de voleibol de alto nivel competitivo. Así, se controlaron el Vasto Medial (VM), el Recto Femoral (RF), el Vasto Lateral (VL), el Semitendinoso (ST) y el Bíceps Femoral (BF). Además, se presentan los resultados obtenidos en una batería de saltos realizados sobre una plataforma de contacto durante este mismo periodo de entrenamiento: Squat Jump (SJ), Countermovement Jump (CMJ), Salto de Remate (REM) y Salto de Bloqueo (BLQ). Se evaluaron dieciséis jugadoras (edad 20,3 ± 1,7 años; peso corporal: 67,75 ± 9,13 kg.; altura: 178,2 ± 7,1 cm.; IMC: 21,41 ± 1,75 kg/m 2) pertenecientes a 2 equipos de Superliga femenina. Los resultados obtenidos muestran claras diferencias en los valores pre-post de todos los parámetros evaluados: Altura de Salto, Velocidad de respuesta normalizada (Vrn), Deformación Máxima radial del músculo (Dm), Tiempo de Activación (Td), Tiempo de Mantenimiento de la contracción (Ts), Tiempo de relajación (Tr); siendo estadísticamente significativos los valores de Vrn del VL (p<0,001; ES=1,11); y encontrando una tendencia estadística en Vrn del RF (p=0,117; ES=0,69). En este sentido, podemos concluir que el entrenamiento produce adaptaciones en la musculatura implicada en la flexo-extensión de la rodilla de jugadoras de voleibol de alto nivel competitivo, y que dichos cambios pueden monitorizarse a través del estudio de la modificación de las características mecánicas musculares evaluadas mediante Tensiomiografía.SIConsejo Superior de Deportes y La Universidad Europea de Madri
