    Get PDF
    El objetivo de este estudio fue describir y comparar las características antropométricas, composición corporal y somatotipo de patinadoras de patinaje artístico sobre ruedas por categorías (junior y senior) y por disciplinas (individual, parejas y danza). Fueron evaluadas 62 patinadoras profesionales (36 en la disciplina de libre, 13 en danza y 13 en parejas). El análisis estadístico utilizado fue una ANOVA para muestras independientes entre disciplinas, y una T de Student para las categorías (junior y senior). Entre la categoría junior y senior no se han encontrado diferencias estadísticas significativas. Las patinadoras junior presentaron un somatotipo endo-mesomorfo, y las patinadoras senior presentaron un somatotipo mesomorfo balanceado. El somatotipo de las patinadoras de parejas y danza fue el mesomórfico balanceado, y el de las patinadoras de libre fue endo-mesomórfico. Este estudio aporta datos biotipológicos de referencia para la población de elite de patinadoras sobre ruedas.The aim of the study was to describe and compare anthropometric characteristics, body composition and somatotype of female roller skaters by levels (Junior and Senior) and by disciplines (freestyle, pairs and dance). Sixty-two world class female roller skaters were assessed (36 freestyle roller skaters, 13 dance roller skaters and 13 pair roller skaters). A one-way analysis of variance (ANOVA) was used to determine if significant differences existed in the anthropometric profile among skating discipline and a student t test in order to assess differences between junior and senior levels. There are no significant differences between junior and senior roller skaters. Junior female roller skaters show an endo-mesomorphic somatotype and senior female roller skaters show a balanced mesomorphic somatotype. Roller dance skaters and roller pair skaters show a balanced mesomorphic somatotype and roller freestyle skaters show an endo-mesomorphic somatotype. This paper, reports specific reference data for world class female roller skaters

    Get PDF
    Its undeniable that throwing speed is one of the most important actions during handball match so it is really important for trainers to improve their knowledge about it. Thus, the aim of the article is threefold: a) to review the scientific studies about the factors that determine throwing speed in team handball to be able to establish the importance of each one b) to summarize the scientific knowledge about throwing speed in handball including aspects that need more studies c) To suggest practical recommendations for handball coaches. Our review revealed that; a) Players with greater elbow angles and higher elbow displacement angles at the release of the ball throw faster b) Hand size, biacromial breadth and finger length are the main anthropometric factors related to throwing speed c) handball players are able to reach a high throwing speeds without losing accuracy, so they should carry out their throwing speed training sessions always at high-speed d) There many different training proposals but with most of them throwing speed is improved. It is necessary to analyse the tactical-technical and conditional work related with throwing speed. e) There are very few studies made in real competition

    The aim of this study was to develop an anthropometric profile on highly skilled male water polo players by specific playing positions. Also, to identify significant relationships between these features an overhead throwing speed in highly skilled male Water Polo players by specific playing positions. Methods: A total of 94 male water polo players (24.5±5.3 yrs) who were playing in the Spanish King´s cup were studied. Subjects were grouped according to their specific playing positions: 15 goalkeepers, 45 offensive wings, 20 center backs and 14 center forwards. Anthropometric assessment was made following ISAK protocols. Hand grip and throwing speed in several situations were also assessed. A one-way analysis of variance (ANOVA) was used to determine if significant differences existed among the four playing positions. Pearson product-moment correlation coefficients (r) were used to determine the relationships of all anthropometric measures with throwing speed and hand grip. The total player’s somatotype was endomorphic-mesomorphic (2.9–5.8–2.3). Center forwards exhibit important anthropometric differences compared with the other specific playing positions in elite male water polo players, but no differences were found in throwing speed by specific playing positions in each throwing conditions. Moreover, a higher number of relationships between anthropometric and throwing speed were found in wings and also in center backs but no relationships were found in center forwards. The data reflects the importance of muscle mass and upper body in the throwing skill. Coaches can use this information in order to select players for the different specific positions

    Performance Factors in Women's Team Handball: Physical and Physiological Aspects—A Review

    Get PDF
    Team handball is an Olympic sport played professionally in many European countries. Nevertheless, a scientific knowledge regarding women's elite team handball demands is limited. Thus, the purpose of this article was to review a series of studies (n = 33) on physical characteristics, physiological attributes, physical attributes, throwing velocity, and on-court performances of women's team handball players. Such empirical and practical information is essential to design and implement successful short-term and long-term training programs for women's team handball players. Our review revealed that (a) players that have a higher skill level are taller and have a higher fat-free mass; (b) players who are more aerobically resistant are at an advantage in international level women team handball; (c) strength and power exercises should be emphasized in conditioning programs, because they are associated with both sprint performance and throwing velocity; (d) speed drills should also be implemented in conditioning programs but after a decrease in physical training volume; (e) a time-motion analysis is an effective method of quantifying the demands of team handball and provides a conceptual framework for the specific physical preparation of players. According to our results, there are only few studies on on-court performance and time-motion analysis for women's team handball players, especially concerning acceleration profiles. More studies are needed to examine the effectiveness of different training programs of women's team handball players' physiological and physical attributes

    Predicting playing status in professional water polo players: analysis by gender

    Get PDF
    BACKGROUND: The aim of this study was twofold: firstly, to identify the characteristics of water polo players that discriminate between women and men based on specific playing positions; and secondly to develop a predicting model to identify the characteristics that are best suited to a given playing position based on gender. METHODS: The study included 130 professional water polo players. Anthropometric characteristics and throwing velocity were analyzed in different situations: no defender or goalkeeper, goalkeeper only and the players made three rapid arm movements and then threw the ball at maximum speed without further feinting with goalkeeper. Measured variables were compared according to gender and player position using discriminant analysis. RESULTS: The predictive model accurately classifies 71.1% of the male players using three variables (arm span, muscle mass Lee and penalty without goalkeeper), and 64.7% of the female players using three variables (triceps skinfold, biceps skinfold and anteroposterior chest breadth). CONCLUSIONS: The anthropometric characteristics and throwing velocity play an important role in identifying the different specific positions in male and female water polo players. In female players, the variables that were determinant in the predictive model, were those associated with body composition.Ministerio de Ciencia e InnovaciĂłn | Ref. DEP2008-0611

    Multidirectional running has been described as an important factor in team sports performance. The aim of the present study was to determine changes in T-test, 505 time, 10 m sprint, squat jump (SJ), countermovement jump (CMJ), countermovement jump right leg (CMJRL), and countermovement jump left leg (CMJLL) following exposure to 12 sessions over 4 weeks of a multidirectional running sprint training intervention in male and female handball players. A total of 31 handball players (15 male and 16 female) were recruited for this study and then randomly assigned to an experimental group (EG) or control group (CG). Male EG players showed improvements in 505 Preferred Side (PS) (p ≤ 0.05), 505 Non-Preferred Side (NPS) (p ≤ 0.05), and 10 m sprint (p ≤ 0.05), while female EG players presented statistically significant improvements between pre- and post-test for the T-test (p ≤ 0.05), 505 PS (p ≤ 0.05), 505 NPS (p ≤ 0.05), and 10 m sprint (p ≤ 0.05). No statistically significant pre- and post-test differences were observed in CG (all p ≥ 0.05) or between male and female players. We found an improvement in handball players’ agility and speed of movement following the intervention protocol, suggesting the need to introduce this program into our training sessions. It may also be necessary to select and develop more specific tests in order to evaluate multidirectional work in handball players
