Masculine, feminine and neutral sports: Extracurricular sport modalities in practice

Abstract: The present work constitutes a novel approach to extracurricular sport modalities. The aim was to analyze the participation model and to determine the relevance of sex in this context. Data from 616 students, aged 15 to 17, were collected. The questionnaire on sport lifestyle from a gender perspective (Alvarinas-Villaverde et al., 2009) was used for assessment. The results showed that sport choice corresponds to sports traditionally associated with men or women. Nevertheless, these coexist with other neutral sports. Girls’ practice was more diverse, while boys’ profile was more resistant to changing classic patterns. Specific strategies are needed to make boys become more interested in typically female activities.

Relación entre la actividad física de los adolescentes y la de madres/padres

Abstract: Este estudio tiene como objetivo analizar la relacion entre la AF de los padres y madres con la de sus hijas e hijos. Participaron en el estudio 1604 adolescentes (807 portugueses, 797 espanoles). Para la recogida de datos sobre practica de AF se utilizo un cuestionario para los adolescentes y otro para los padres y madres. El efecto de la AF de las madres y de los padres sobre la AF de sus hijas e hijos fue evaluado a traves de regresion logistica multinomial. Los adolescentes con progenitores fisicamente activos practicaban semanalmente mas veces AF no organizada (59.4% vs. 37.9%, p<0.001), organizada (39.6% vs. 22.7%, p<0.001) y durante mas tiempo (24.8% vs. 17.0%, p=0.010) que los que tenian madre y padre poco activos. Los adolescentes con madres activas y padres poco activos (OR=1.8, 95% IC: 1.3-2.7, p=0.002), y los que tenian ambos activos (OR=2.1, 95% IC: 1.4-3.2, p<0.001) tenian mayor probabilidad de practicar AF no organizada. Tener el padre activo y la madre poco activa (OR=1.6, 95% IC: 1.1-2.1, p=0.024) y tener ambos activos (OR=1.6, 95% IC: 1.1-2.3, p=0.017) estaba asociado a una mayor probabilidad de practica de AF organizada. El presente estudio demostro la existencia de una relacion entre la AF de padres y madres con la AF de sus hijos e hijas.

Longitudinal Study of Individual Exercises in Elite Rhythmic Gymnastics.

Abstract: The performance evolution in rhythmic gymnastics depends on changes in code of points. At the beginning of each Olympic cycle the code of points changes and therefore, the content of the competition exercises, as well. This study aimed to analyze - for each apparatus - the evolution of number of technical elements and final score over the last two decades (last 13 world championships), how they have been affected by changed code of points, and how the final score relates to the number of technical elements performed. The sample consisted of 416 exercises in five apparatus: ball (96), rope (40), hoop (96), ribbon (88), and clubs (96). The following variables were gathered: code of points, apparatus, technical group, total number of elements, final classification, and final score. Linear mixed-effects models were used to examine the effects on the number of elements and final score in each apparatus. The number of technical elements increased in all apparatus, between 7.4 and 20% over a 10-year period. There were mixed evolutions of final score between the different apparatus, between -6.3 and 14% over a 10-year period. There is small increase in number of elements in hoop and a small decrease in rope after a code change. There was a small decrease in final score in championships after a code change in hoop, moderate in clubs and ribbon, and large in rope. There was a negative relationship between number of elements performed and final score in clubs. In conclusion, the code change generally effects the final score negatively, but there were apparatus specific effects of code change on number of elements and relationship between number of elements and final score.

Acute effects of training load on contractile properties during a competitive microcycle in elite soccer players.

Abstract: The aim of this study was to examine changes in muscle contractile properties across a microcycle of training in professional soccer players during the in-season period. Nineteen professional soccer players were assessed with tensiomyography (TMG) on the biceps femoris and rectus femoris before and after 5 training sessions of an in-season microcycle. Training load was quantified during each training session. Significant differences were observed in training load variables across different training sessions, with the last training session prior to match day showing the lowest values for all training load variables. Significant pre- to post-session increases were observed in muscle stiffness of the rectus femoris and biceps femoris during the first four training sessions (effect size range, 0.5 to 0.9). However, no significant differences were observed in muscle contraction time and contraction velocity from pre- to post-session. In addition, repeated measures correlation analysis revealed significant relationships between absolute change in muscle stiffness of the rectus femoris and training duration, high-speed distance covered during training, and training average distance. The current study shows that players are physically taxed on their muscular stiffness by the training load. Post-session muscular stiffness assessment should be recommended to determine neuromuscular status and readiness in professional soccer players during the competitive season.

Physical demands of different positions in FA Premier League soccer

Abstract: The purpose of this study was to evaluate the physical demands of English Football Association (FA) Premier League soccer of three different positional classifications (defender, midfielder and striker). Computerised time-motion video-analysis using the Bloomfield Movement Classification was undertaken on the purposeful movement (PM) performed by 55 players. Recognition of PM had a good inter-tester reliability strength of agreement (κ = 0.7277). Players spent 40.6 ± 10.0% of the match performing PM. Position had a significant influence on %PM time spent sprinting, running, shuffling, skipping and standing still (p 0.05). Players spent 48.7 ± 9.2% of PM time moving in a directly forward direction, 20.6 ± 6.8% not moving in any direction and the remainder of PM time moving backward, lateral, diagonal and arced directions. The players performed the equivalent of 726 ± 203 turns during the match; 609 ± 193 of these being of 0° to 90° to the left or right. Players were involved in the equivalent of 111 ± 77 on the ball movement activities per match with no significant differences between the positions for total involvement in on the ball activity (p > 0.05). This study has provided an indication of the different physical demands of different playing positions in FA Premier League match-play through assessment of movements performed by players.
