Effects of contrast strength training with elastic band program on sprint, jump, strength, balance and repeated change of direction in young female handball players

Maximal strength, power and his derivates (sprint, change of direction repeatedly and jump) are considered as major determinants of success in elite handball players. Contrast strength training with elastic band (CSTEB) program is form of resistance training, and may play an important method of training to improve this quality. This study examined the effects of 10-week contrast strength training with elastic band (CSTEB) program on physical performance in young female handball players. Thirty participants (age: 15.7 ± 0.3 years; body mass: 63.7 ± 3.7 kg; body height: 166.8 ± 3.8 cm; body fat: 26.9 ± 3.4; and Maturity-offset: 2.9 ± 0.3 years) were randomly assigned between experimental group (EG; n = 15) and control group (CG; n = 15). Two-way analyses of variance (group × time) were assessed for handgrip; back extensor; medicine ball throw; 30-m sprint times; Modified Illinois change-of-direction (Illinois-MT); four jump tests [(squat jump (SJ), countermovement jump (CMJ), countermovement jump with arms (CMJA) and five jump test (5JT)]; static (stork) and dynamic (Y balance) balance tests; and repeated sprint T-test (RSTT). The EG enhanced all strength performance [handgrip right, handgrip left, back extensor strength and medicine ball throw (p < 0.001)] compared to CG. The EG enhanced all sprint performance. The EG also improved performance in the Illinois-MT. All jump performance improved significantly [SJ (p = 0.007), CMJ (p = 0.001) and CMJA (p = 0.001)] except 5JT in the EG. Of the same, 3 of 4 repeated sprint T-test scores [RSTT-Best-Time, RSTT-Mean-Time and RSTT-Total-Time] increased significantly in the EG relative to the CG. Conversely, there were no significant changes in balance performance between groups. It is concluded that 10-weeks of CSTEB improved physical performance (strength, sprint, change of direction, jump, and repeated change of direction) measures in young female handball players.

Establishing Normative Reference Values for the Utah Seated Medicine Ball Throw Protocol in Adolescents

The seated medicine ball throw (SMBT) is a field test intended to assess upper-body muscular power by measuring the maximal distance an individual can throw a medicine ball from an isolated, seated position. The SMBT has been used to assess upper-body power in various populations and to establish concurrent validity for other measures of upper-body power such as the bench press power test and the plyometric push-up. The SMBT is less costly and simpler to incorporate into a field test battery than other upper body power assessments. While the SMBT is a valid, reliable field test for upper-body power, normative reference standards for most populations, including adolescent (12-15 years old) physical education students, do not exist. Purpose: This study reports distances thrown in the SMBT to establish normative reference values in male and female physical education students, ages 12-15 years old. Methods: One hundred thirteen untrained male and female physical education students aged 12-15 years performed the SMBT field test three times on a single testing day. Participants threw a 2kg medicine ball with a 19.5 cm diameter while seated at 90 degrees after recording height and weight. Results: Participant data was separated by age gender for analysis. Mean and standard deviation for the SMBT for males was 4.3+/-0.7m and 5.2+/-0.8 m for ages 12-13 and 14-15, respectively, and for females was 3.4+/-0.5m and 3.7+/-0.5m for ages 12-13 and 14-15, respectively. Pearson correlation coefficients for between-trials comparisons for males and females ranged from r=0.85-0.97. Pearson correlation coefficients for average SMBT and age of participants was r=0.93. Normative reference values as percentile ranks for the SMBT scores for age groups 12-13 and 14-15 among males and females, respectively, were also established. Conclusion: The data presented provides an initial set of normative reference standards for coaches and students to determine upper-body muscular power using the SMBT.

Acute and delayed effects of strength training in ball velocity and accuracy in young competition tennis players

This study aimed to investigate the acute and delayed effects of medicine ball throws and resistance training in ball velocity and accuracy of serve, forehand and backhand in young competition tennis players. A crossover-randomized design was used with 10 competition tennis players (6 girls and 4 boys between 14 and 18 years old). The subjects performed 6 stroke test sessions, 3 for each strength protocol. The velocity and accuracy of strokes were measured before (basal situation), 3 minutes, 24 and 48 hours after the protocol. Medicine ball throws protocol was performed by accomplishing 3 sets of 6 repetitions using a 2 kg ball, throwing it at maximal speed. Resistance training protocol was performed by accomplishing 3 sets of 6 repetitions at 75% one-repetition maximum, lifting the load at maximal speed of bench press, dead lift, one hand row and half squat. There were no significant (p > 0.05) differences in all strokes, regarding ball velocity and accuracy after each method and each recovery time, compared to the basal situation. These results suggest that medicine ball throws and resistance training methods have no acute and delayed detrimental effects on stroke velocity and accuracy in young competition tennis players.

Fitness testing in tennis: Influence of anthropometric characteristics, physical performance, and functional test on serve velocity in professional players

The aims of this study were to examine the relationship between anthropometric variables, physical performance, and functional test with serve velocity regarding tennis players’ level and to design regression models that effectively predict serve velocity. A sample of sixteen male tennis players participated in this study (national level = 8, professional level = 7). Anthropometric measurements (body mass, height, body mass index and body segments) and physical test (hand strength, countermovement jump, jump on serve, and serve velocity) and functional test (medicine ball throw overhead and shot put) were performed. No differences in anthropometrics and physical test were found between national and professional levels. A significant positive correlation (p < 0.05, ranging for 0.603 to 0.932) was found between some anthropometrics measurements (body mass, height, arm, forearm, and leg segments), physical parameters (hand strength, countermovement jump) and functional test (medicine ball throw shot put and overhead) with serve velocity for all tennis players. Multiple regression analysis indicated that medicine ball throw shot put was the most important test to explain serve velocity (r2 = 0.869). The results showed how the combination of physical and anthropometric factors have an impact on serve velocity. In addition, a new functional fitness test (medicine ball throw shot put) is proposed as an alternative to traditional medicine ball throw overhead due to its high reproducibility (inter-trial reliability) and predictive validity values, as well as by multi-segmental coordination movement similar to tennis serve.

Para-Badminton: aptidão física relacionada ao desempenho de atletas brasileiros em cadeira de rodas

O Para-Badminton (PBd) conta com adaptações em suas regras e no seu espaço de jogo de acordo com a classe esportiva, mantendo a essência do jogo oficial. A presente pesquisa apresenta um estudo do tipo exploratório, com delineamento quantitativo cujo objetivo é avaliar, através de testes adaptados, a aptidão física relacionada ao desempenho de atletas brasileiros de PBd. Foram avaliados cinco atletas com deficiência física, usuários de cadeira de rodas, do sexo masculino, com idades entre 18 e 46 anos. Para a coleta de dados, foram utilizados três testes adaptados, sendo: o zigue-zague modificado para avaliar a agilidade; a corrida de 40 metros em cadeiras de rodas esportivas para avaliar a velocidade e, o arremesso de medicine ball para avaliar a potência de membros inferiores. Os resultados médios obtidos nas variáveis: a) agilidade foi de 15,6 segundos; b) velocidade foi de 8,6 segundos; e c) potência de membros superiores de 6,2 metros. Pode-se concluir que os jogadores de PBd, em sua maioria, apresentaram melhores scores do que os estudos com atletas de atletismo Paralímpico, basquete e handebol em cadeira de rodas. Jogadores de PBd necessitam dessas competências bem desenvolvidas em razão das especificidades do jogo (área de jogo reduzida, modalidade rápida, grande volume de deslocamentos e batidas na peteca). Assim, os resultados aqui apresentados podem auxiliar na prescrição e elaboração de programas de treinamento de atletas da modalidade, bem como para estudos que tenham a intenção de verificar a aptidão física voltada ao desempenho de atletas de PBd.

[ID 57089] ANÁLISE CORRELACIONAL DO DESEMPENHO FUNCIONAL E MUSCULAR DO OMBRO DE ATLETAS DE BASQUETE EM CADEIRA DE RODAS E REGULAR

Objetivo: Analisar o desempenho funcional e muscular da articulação glenoumeral de atletas do basquete em cadeira de rodas e comparar com atletas do basquete regular. Metodologia: Oito atletas do basquete em cadeira de rodas e oito atletas do basquete regular fizeram parte da amostra. Para a análise funcional, os testes realizados foram o maximal pass e o arremesso de medicine ball. Em seguida, foi realizada a avaliação do desempenho muscular dos músculos rotadores externos e internos do ombro, utilizando dinamômetro isocinético, no modo concêntrico-concêntrico nas velocidades angulares de 60º/s., 180º/s. e 240º/s. O teste t pareado foi utilizado para a comparação entre os membros e o teste t não pareado para a comparação entre os grupos. O teste de correlação de Spearman foi utilizado para verificar as correlações entre as variáveis funcionais e musculares. Foi considerado o nível de significância de p<0,05. Resultados: Não ocorreram diferenças estatisticamente significativas entre os grupos, tanto nas variáveis funcionais quanto nas musculares; assim como não existiram diferenças entre os membros nas análises de desempenho muscular. No entanto, correlações fortes e significativas foram encontradas entre o arremesso de medicine ball e os valores médios de pico de torque dos rotadores externos e internos do ombro (p<0,05). Conclusão: As fortes correlações entre o teste do arremesso de medicine ball e os valores médios de pico de torque sugerem que este teste funcional é uma ferramenta útil e pode ser considerada para a avaliação de desempenho muscular quando não é possível a utilização da dinamometria isocinética.
