Why do female and male taekwondo athletes win the bout? An analysis based on the Olympic weight category and the result of the bout
2020
Combat sports such as taekwondo, where athletes compete against an opponent require control of technique and tactics, as well as knowing the optimal performance of opponents to win the bout. Therefore, the aim of the present study was to analyse the Olympic competitors (London Olympic Games), according to the weight category (fly, feather, light and heavy) and according to the performance in their fighting (winner vs. loser) in each gender. An observational methodology was used, following a nomothetic, follow-up and multidimensional design of 302 individual performances. The statistical analysis used an ANOVA and T Student test for comparing frequencies. The results obtained indicate signif…

Effects of between-set interventions on neuromuscular function during isokinetic maximal concentric contractions of the knee extensors
2011
The presents study investigated the effects of between-set interventions on neuromuscular function of the knee extensors during six sets of 10 isokinetic (120°·s(-1)) maximal concentric contractions separated by three minutes. Twelve healthy men (age: 23.9 ± 2.4 yrs) were tested for four different between-set recovery conditions applied during two minutes: passive recovery, active recovery (cycling), electromyostimulation and stretching, in a randomized, crossover design. Before, during and at the end of the isokinetic session, torque and thigh muscles electromyographic activity were measured during maximal voluntary contractions and electrically-evoked doublets. Activation level was calcul…
Mediadores psicológicos y motivación deportiva en judocas españoles. Psychological mediators and sport motivation in Spanish judokas.
2006
El presente trabajo analizo las diferencias de la motivacion en situacion precompetitiva de judocas en funcion de los mediadores psicologicos (percepciones de competencia, apoyo a la autonomia y relaciones sociales), tal y como postula el Modelo Jerarquico de la Motivacion Intrinseca, Extrinseca y Amotivacion (Vallerand, 1997, 2001; Vallerand y Losier, 1999). Se empleo una muestra de 181 judocas de edades comprendidas entre los 14 y 16 anos. Utilizamos una metodologia selectiva, con diseno prospectivo simple. Los datos se analizaron mediante un MANOVA, tomando como variables independientes los mediadores psicologicos y el sexo de los deportistas y como variables dependientes cada una de las…
Validity and reliability of a pictorial scale of physical self-concept in spanish children. [Validez y fiabilidad de la escala pictográfica de autoco…
2019
The pictorial scale of Physical Self-Concept in Children (P-PSC-C) is a relatively new instrument for investigating physical self-concept in childhood. The current study aims to examine the validity and reliability of the Spanish version of the P-PSC-C, and also to analyse the validity according to the children’s age. A sample of 365 primary school age (M = 9.21, SD = 1.92) students participated; divided in two groups, those aged 9 or younger and those 10-11 years old. Surveys were used to assess perceived physical concept individually. Confirmatory factor analysis (CFA) with diagonally weighted least square estimator specifically designed for ordinal data and a scaled test statistic was co…

2013
Pese a la enorme relevancia del futbol en la sociedad espanola, algunas de sus pautas y procesos caracteristicos han sido poco examinados por la investigacion sociologica.

El estudio se basa en una encuesta representativa de la poblacion espanola realizada en 2007 por el Centro de Investigaciones Sociologicas (CIS) que conto con una muestra de 2.473 entrevistas. Los resultados obtenidos ponen de manifies…
Effects of a training program on stable vs unstable surfaces on postural stability. [Efectos de un programa de entrenamiento en superficies estables …
2019
The training surface can modulate the body’s response to training stimuli. The purpose of the article was to determine the influence of two types of training programs on stable/unstable surfaces on postural stability. 20 physically active participants with no history of lower limb injuries were randomly assigned to 3 groups (Control, Unstable Training, Stable Training), and performed supervised training in 16 sessions. Dynamic postural stability and static stability were assessed and tests were performed at baseline after completion of the training and 1, 2 and 4 weeks after the training process. The stable surface training group improved dynamic stability between the pre-test and the two f…
Football clubs ownership and management. The fans perspective. [Propiedad y gestión de los clubes de fútbol. La perspectiva de los aficionados].
2014
Two decades after the entry into force of the law that stimulated the conversion of the football clubs into public limited sports companies (Sport Law of 1990), this article presents an investigation on the perceptions that the fans have of its configuration and functioning. The changes that have taken place in the ownership and management of the clubs are examined from the point of view of the fans, as well as the consequences that these changes have had in their relation with the clubs. Following the presentation of the process that led to the transformation of the Spanish clubs of football in public limited sports companies, the main results of a qualitative research with 25 football fan…
The Influence of Fatigue on Throwing and YBT-UQ Performance in Male Adolescent Handball Players
2020
Purpose: The goal of the present study was to assess the effects of fatigue on throwing and Upper Quarter Y Balance Test (YBT-UQ) performance in male adolescent handball players. We hypothesized that throwing and YBT-UQ performance will be decreased in response to an upper-body fatigue-protocol.Method: All male participants (N = 24, age: 14.8 ± 0.7 yrs) were handball players of a regional youth selection team. A radar gun was used for the assessment of throwing velocity. The YBT-UQ was executed assessing medial, inferolateral and superolateral reach directions normalized to the upper limb length together with a composite score. Immediately following a fatigue protocol of different sets of p…
A Group-Based 8-Week Functional Interval-Type Outdoor Training Program Improves Physical Performance in Recreationally Active Adults
2022
Even though physical activity is an important aspect of health, lack of time or motivation impede people from working out regularly. One type of training program that is both efficient and motivating is functional interval-type outdoor training. To evaluate this, our study had 81 participants complete a battery of physical performance tests (incremental treadmill test, core stability test and functional fitness test) before and after an 8-week outdoor interval-type training intervention. Training procedures included multimodal and high-intensity exercises performed in consistent, small groups. Results showed that the interval training program produced significant increases in the interventi…
