Throwing speed in team handball: a systematic review

29 p.Its undeniable that throwing speed is one of the most important actions during handball match so it is really important for trainers 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 lose 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

Evolució de la condició física en jugadores d’handbol en les categories infantil, cadet i juvenil

En aquesta investigació s’analitza la condició física de 91 jugadores d’handbol, amb edats compreses entre els 13 i els 18 anys, distribuïdes en tres categories diferents, infantil (n = 30), cadet (n = 32) i juvenil (n = 29). La investigació té caràcter descriptiu i transversal. El principal objectiu és analitzar l’estructura condicional de les jugadores. Per a la valoració es va aplicar la bateria Eurofit, la bateria de Bosco i test d’Abalakov. Es van trobar diferències significatives entre la categoria infantil-cadet en cinc de les 14 variables estudiades, i cap entre la categoria cadet-juvenil. Els millors resultats es van produir en la categoria juvenil. En general, les restants variables sempre van assolir millors valors que la població escolar (en aquelles variables en les quals la comparança va ser possible), però pitjors que els valors presentats per les jugadores de les seleccions espanyoles. En les proves que van valorar la força del tren inferior, els resultats indiquen que a major categoria les diferències són menors entre categories

Water polo throwing speed and body composition: an analysis by playing positions and opposition level

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

A Training Proposal to Improve Multidirectional Running Technique in Male and Female Handball Players: A Pilot Study

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

Power-strength curve in basketball players

The purpose of this study was to examine the power-strength curve in a half squat exercise in trained basketball players of the EBA league. For that, a cross sectional, descriptive study was carried out to 8 high-level male basketball players. After controlling the participants 1RM, a progressive test, consisted on moving loads of 30, 45, 60, 70 and 80% of 1RM as fast as possible in the concentric phase, was performed. The participants showed the highest peak power output with loads of 45% of 1RM. These results differ from the wide literature, which shows values ranged between 30% and 70% of 1RM; this can be due to: a) the analyzed sample; b) the experience of the participants; and c) the methodology used for the record. Therefore, we concluded that, the basketball players studied present values of peak power output, in competitive period, near to 45% of 1RM in the half squat exercise

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

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
