    The aim of the study was to compare kickboxing competitive levels and genders in anthropometric, physical and physiological attributes. The sample was composed of four groups (subelite: 6 men and 4 women; amateur: 10 men and 8 women). Anthropometric measurements, 20-meter Shuttle Run aerobic test, Countermovement Jump (CMJ), Medicine Ball Throw (MBT), Bench Press and Back Squat Maximal Strength and Wingate-test for upper (UB) and lower-body (LB) before were used. We found that the subelite male and female kickboxers achieved significantly higher UB (male: subelite = 6.1±0.6 and 7.6±0.8 vs. 5.2±0.7 and 6.5±0.9 W.kg–1, respectively; female: subelite = 4.8±0.6 and 5.9±0.8 vs. amateur = 3.7±0.8 and 4.1±1.1 W.kg–1, respectively), LB mean and peak power (male: subelite = 8.5±0.9 and 10.9±0.9 vs. 7.1±1.1 and 9.3±1.2 W.kg–1, respectively; female: subelite = 6.5±0.8 and 8.6±1.1 vs. amateur = 5.3±0.9 and 6.7±1.4 W.kg–1, respectively). MBT (male: subelite = 4.6±0.3 vs. amateur = 4.1±0.4 m; female: subelite = 3.9±0.4 vs. amateur = 3.2±0.5 m) and maximal oxygen uptake (male: subelite = 54.6±4.3 vs. amateur = 49.1±4.6 ml.min–1.kg–1; female: subelite = 47.6±3.2 vs. amateur = 42.2±3.8 ml.min–1.kg–1) than amateur kickboxers. The effects demonstrated significant difference between male and female amateur kickboxers for anthropometric, physical and physiological performance (P<0.05) and a sexual dimorphism when compared the female subelite level with male groups. The performance of male and female kickboxers primarily depends on the anaerobic alactic and aerobic power

    The purpose of the present study was to correlate the external load of an official soccer match with the percent change in the countermovement jump variables in professional soccer players and to analyze the differences between moments (pre, immediately post and 24 hours post-match). The main findings were the correlations between the percentage of change in the CMJ variables and the external load very strong between JH1 with ACC4; JH2 with D23, HSR, ACC1 and DCC2; JT1 with ACC4; PP1 with ACC3; RFDB1 with ACC4; RPD1 and RPD2 with D7. On the other hand, differences were found in PF between pre and post, in PP between post and 24h, RFDB between pre and post. Through our results we conclude that the change in the vertical jump with countermovement is correlated with the external load performed during a match in professional players, so that the assessment of the mechanical variables of the jump on force platforms is a practical option to assess fatigue after a soccer match. An individual analysis is also necessary to know the intra-player differences because the group analysis is influenced by the external load

    [ES] El taekwondo (TKD) es un deporte de combate basado en patadas altas a la cabeza, patadas giratorias y saltos. Las combinaciones técnico‐tácticas veloces y ágiles son una característica esencial de esta disciplina. Esta revisión contribuye al análisis crítico de las acciones técnico‐tácticasde los atletas de TKD, estudiando los momentos de pausa y esfuerzo propios de los combates en competiciones oficiales. Esta revisión investigó las disposiciones tácticas (i.e., ataques, defensas y bloqueos), rendimiento técnico (puntos), patadas y golpes, según la categoría de peso, edad y género. De hecho, los cambios de reglas acaecidos durante estos años han incrementado las acciones defensivas en seniors, con alrededor del 50% de acciones ofensivas, seguidas del 30% y 20% de acciones defensivas y bloqueos respectivamente. Los juveniles tienden a adoptar una estrategia ofensiva, con aproximadamente el 90% de acciones ofensivas. Desde la introducción del sistema electrónico de puntuación, los atletas de alto rendimiento necesitan ejecutar técnicas muy precisas y correctas para lograr puntuar. Por ello, los atletas de élite utilizan técnicas a corta distancia con patadas de la pierna retrasada. Esta acción demuestra eficacia para lograr puntos y ayuda a los competidores a aumentar su capacidad defensiva y en sus contraataques. En consecuencia, los programas de formación para atletas de élite de TKD deberían adaptarse a las reglas de competición, categorías de peso, sexo y grupos de edad.[EN] Taekwondo (TKD) is a combat sport, focusing on head‐height kicks, spinning kicks and skipping. The emphasis on technical‐tactical combinations with speed and agility is an essential characteristic of this modality. Therefore, this review aims to contribute to the critical analysis of technical‐tactical actions of TKD athletes, using relative effort and pause moments of official competitions. This review investigated tactical arrangements (i.e., attacks, defenses and blocks), technical performance (points), kicks and punches, regarding to weight category, age class and gender. In fact, rule changes in recent years have increased defensive actions in the senior category, with about 50% of actions in attacks, followed by 30% in defenses and 20% in blocking actions. While juniors tend to adopt an offensive strategy, with about 90% of the actions in attacks. Since the introduction of the scoring electronic system, high‐performance athletes need to perform accurate and correct techniques to achieve scoring, so elite athletes have used short‐distance techniques with kicks from the back leg. This action shows effectiveness in scoring and assists competitors in increasing defensive capability and counter‐attacks. Consequently, training programs need to be specific to the rules, weight divisions, gender and age categories in elite athletes in TKD.[PT] O taekwondo (TKD) é um esporte de combate que focaliza em chutes na cabeça, giratórios, e saltos. A enfase em combinações técnico‐táticas com velocidade e agilidade é uma característica essencial dessa modalidade. Portanto, esse artigo objetiva contribuir com uma análise crítica sobre ações técnico‐táticas de taekwondistas, utilizando momentos relativos de esforço e pausa em competições oficiais. Essa revisão investigou arranjos táticos (i.e., ataques, defesas e bloqueios), performance técnica (pontos), chutes e socos, referentes a categoria de peso, classe de idade e gênero. De fato, as modificações das regras nos anos atuais aumentou as ações defensivas entre adultos, com cerca de 50% das ações em ataques, seguido de 30% de defesas e 20% de ações de bloqueio. Enquanto juvenis tendem a adotar uma estratégia ofensiva, com cerca de 90% das ações em ataques. Desde a introdução do sistema eletrônico, atletas de alto rendimento necessitam executar técnicas precisas e corretas para conquistar pontuação, por isso, atletas de elite tem utilizado técnicas de curta distância com chutes realizados pela perna de trás. Essa ação mostra eficácia em pontuar e auxilia competidores no aumento da capacidade defensiva e em contra‐ataques. Por sua vez, programas de treinamento precisam ser específicos diante das regras, necessidades de categorias de peso, gênero e idade em atletas de elite no TKD

    Objetivo: Este estudo objetivou verificar os níveis de ansiedade-traço em judocas, da classe juvenil (entre 14 e 18 anos) no período pré-competitivo e competitivo. Método: Para tanto, foram analisados 40 atletas (20 de cada sexo) com 5 ± 2 anos de prática de Judô. O instrumento utilizado foi o “Sport Competition Anxiety Test” (SCAT). Para observar diferenças, utilizou-se Friedman e Mann-Whitney, p ≤ 0,05. Para verificar correlações, usou-se o coeficiente de correlação de Spearman. Resultados: Os resultados demonstraram que homens e mulheres em competição apresentaram maior ansiedade em relação ao período de treinamento. Quando comparados os gêneros em interação com o momento, o grupo feminino competitivo demonstrou maior ansiedade que os demais grupos. Foram constatadas correlações negativas e significantes entre a ansiedade, nos momentos pré-competitivo e competitivo, com o tempo de prática da modalidade. Conclusões: Esses dados sugerem que o trabalho preparatório durante o dia da competição deva ser diferente entre o masculino e o feminino, pois enquanto no feminino seria preciso dar atenção ao controle da ansiedade, no masculino outros aspectos poderiam ser analisados/considerados na preparação do atleta no dia da competição

    Este artigo tem como objetivo analisar o perfil epidemiológico dos cuidadores informais dos idosos com déficit de autocuidado. Foi realizado um estudo observacional, transversal e descritivo. Foram avaliados os cuidadores informais que pertenciam a todas as Estratégias de Saúde da Família do município de Criciúma-SC. Responderam ao questionário 139 cuidadores. A idade média foi de 50,1(±12,9) anos e a maioria do sexo feminino (93,5%) e casada (67,6%). A ocupação predominante foi “do lar” (52,5%), apenas 20,1% considerava-se “cuidador”. Os filhos (55,4%) e esposas (15,8%) foram os principais cuidadores. Os católicos (71,9%) e evangélicos (26,6%) representaram as principais religiões. O grau de instrução predominante foi o ensino fundamental incompleto (60,4%) e o menos encontrado foi o superior (2,1%). A renda familiar de 79,8% cuidadores variou entre dois e cinco salários mínimos. Quanto à saúde 59,7% dos cuidadores apresentaram alguma morbidade sendo a Hipertensão (14,4%); e 56,1% relataram o uso de medicamentos. O perfil predominante dos cuidadores foi composto por mulheres de meia idade, casadas, do lar, com baixa escolaridade e renda, apresentando doenças associadas à faixa etária. Nosso estudo traz alguns aspectos relativos ao cuidador informal que poderão auxiliar aos profissionais de saúde a conhecê-los melhor, e assim, desenvolverem intervenções com vistas ao planejamento e à implementação de uma assistência integral aos idosos e aos próprios cuidadores.

    The present study compared emotional intelligence and anxiety between six combat sports of lower, intermediate and high-level female and male athletes. The sample was composed by 444 athletes (age: 24.7 8.8 years, body mass: 72.4 12.1 kg, height: 1.82 0.3 m, and practice time: 13.1 7.4 years) separated by sex (male n = 273, female n = 171) from different combat sports (jiu-jitsu n = 142, judo n = 137, karate n = 57, kendo n = 63, taekwondo n = 25, and freestyle wrestling n = 20) of three levels (high-level n = 57, intermediate n = 137 and low-level n = 142). Inventory of situations and anxiety response (ISRA) provided an independent evaluation for the three systems: cognitive, motor and physiological, as well as a total with four factors of analysis (anxiety before the evaluation, interpersonal, phobic and before habitual, and daily situations). Trait Meta-Mood Scale (TMMS-24) verified emotional intelligence scales. Descriptive results are demonstrated by percentage or median (first quartile Q1; third quartile Q3), Kruskal-Wallis and Mann-Whitney tests were conducted to compare groups, p 0.05. The main results demonstrated 10% more total anxiety for wrestling and judo compared to the other groups (p 0.05). Female athletes showed 15% more anxiety than men, while emotional attention demonstrated 10% better results for women. Significant differences were observed between high- versus low-level athletes in the total anxiety with 85 (44; 143) versus 122 (69; 186) of ISRA index and emotional repair with 30 (25; 34) versus 27 (22; 32) of TMMS-24 index. Emotional intelligence seems to be higher in female and in higher level, while anxiety appears to be prevalent in judo and wrestling, low-level and in female athletes. These outcomes provide support for the hypothesis that emotional abilities are an important contributor to emotional intelligence, particularly differentiating high level athletes than other levels. Results can be incorporated into strategies for reducing anxiety and improving emotional intelligence, considering particularities of gender and level groups.post-print274 K

    IT NECESSARY TO NORMALIZE JUMP TEST RESULTS TO ANTHROPOMETRIC PARAMETERS?

    The purpose of the present study was to analyse the relationship of different normalization methods in the jump performance, obtained from a digital application (My Jump 2 ®). 189 young women made up the sample. Each of them had to perform three attempts of a bilateral countermovement jump (CMJ) in front of a mobile device. The jump height (JH) and power (P) were the main results, which were processed to normalize them. The JH was normalized to height (JH/H) and to leg length (JH/LL). P was normalized to body mass (RP), while force values were divided by the time of jump to get the Explosive Index of Strength (EIS). The results showed a good association and poor prediction between the variables JH and P, not so between JH and EIS, where no significant relationship was observed. However, a strong relationship was observed between JH / LL and RP (r = 0.801; r2 = 0.641; p KEYWORDS: Smartphone app, vertical jump, biomechanics
