“…Olahraga yang tergolong individu ini memiliki berbagai manfaat seperti pertahanan diri, kesehatan, seni, ataupun peningkatan psikologis atlet. Selain itu, karate menitik beratkan pada kegiatan pengembangan kepribadian dan juga ketangkasan (Sastre et al, 2021). Hal ini juga berkaitan dengan kumite, yaitu penyatuan aspek dalam satuan waktu untuk meraih poin dalam pertandingan (Zhu et al, 2020a).…”

Beladiri karate mengutamakan unsur kekuatan dan kecepatan serangan terutama pada kumite. Secara empiris, penelitian ini bertujuan untuk menguji korelasi antara fleksibilitas pinggang dan kekuatan otot lengan terhadap kecepatan pukulan gyaku tsuki. Sebuah studi kuantitatif korelasional dengan melibatkan 30 karateka Kabupaten Sleman (Age= M 16,1 ± SD 0,758). Pengukuran menggunakan tes sit and reach untuk fleksibilitas pinggang, tes push up untuk kekuatan otot lengan, dan software kinovea sebagai pengukur kecepatan gyaku tsuki. Sehubungan dengan hal tersebut, hasil penelitian menunjukkan bahwa kedua variabel (fleksibilitas pinggang dan kekuatan otot lengan) secara bersama memiliki korelasi signifikan dengan kecepatan gyaku tsuki dengan probabilitas sebesar 0,023. Namun, fleksibilitas pinggang memiliki peranan yang lebih kuat dengan probabilitas sebesar 0.03 dibandingkan kekuatan otot lengan hanya sebesar 0.037. Temuan ini menunjukkan bahwa komponen fleksibilitas dan kekuatan adalah komponen yang perlu diperhatikan oleh pelatih untuk penyusunan program latihan ke depannya Waist flexibility and arm muscle strength: how do they contribute to gyaku tsuki hitting speed? AbstractKarate martial arts prioritize elements of strength and attack speed, especially on kumite. Empirically, the study aimed to test the correlation between waist flexibility and arm muscle strength against the speed of gyaku tsuki punches. A quantitative correlational study involving 30 Sleman County karateka (Age= M 16.1 ± SD 0.758). The measurement uses sit and reach tests for waist flexibility, push-up tests for arm muscle strength, and kinovea software as gyaku tsuki speed gauges. In this regard, the results showed that both variables (waist flexibility and arm muscle strength) together had a significant correlation with gyaku tsuki speed with a probability of 0.023. However, waist flexibility has a stronger role with a probability of 0.03 compared to arm muscle strength of only 0.037. These findings suggest that the components of flexibility and strength are components that need to be considered by the coach for the preparation of the exercise program in the future.

“…This approach to methodological integration has been applied in psychological research on spontaneous behavior in the fields of health (e.g., Casarrubea et al, 2018;Castañer et al, 2017;Puigarnau et al, 2016), physical activity and sport (e.g., Amatria et al, 2017;Fernandes et al, 2020;Fernández-Hermógenes et al, 2021;Gutiérrez-Santiago, 2013;Lapresa et al, 2018;Prieto-Lage et al, 2020;Sastre et al, 2021), and physical education (e.g., Camerino et al, 2019;Castañer et al, 2009Castañer et al, , 2011Castañer et al, , 2020Prat et al, 2019;Valero-Valenzuela et al, 2020). Indeed, there are several software programs to conduct visualization and annotation, but with some weakness related to all the necessary features of viewing, coding, analysis and administration of the results, resulting in scattered data and necessitating the export of these results to other complementary software programs (Hernández-Mendo et al, 2014;Love et al, 2019).…”

This paper aims to offer a free software program, LINCE PLUS, suitable for systematic observational studies in sports and health, conducted in natural contexts such as training, education or psychology. Using one or several videos simultaneously, different parameters such as behaviors, decision-making or strategies can be analyzed. The software includes several functionalities for studies that researchers need to utilize throughout the observational study process. Collaborative work can be accomplished by using simultaneous videos and multiple observers. The results of all research conducted by LINCE PLUS are offered inside the application in real time, enabling common calculations or including specific analysis with R language without the need for any other external tool. Moreover, LINCE PLUS shows the results of each study with interactive charts or, if needed, it exports the data to specific data analysis software programs (e.g., SAS, Excel, Theme, GSEQ 5, Hoisan). We include examples of sports and health studies that have been conducted with LINCE PLUS to show the suitability of this software program.

En metodología observacional, para abordar la fiabilidad de los datos ya registrados, suele recurrirse a coeficientes de concordancia, coeficientes de correlación o a la teoría de la generalizabilidad; además, cada vez está tomando mayor protagonismo la concordancia consensuada. Esta forma de concordancia trata de lograr la coincidencia entre los observadores antes del registro. A pesar de su creciente presencia en estudios observacionales, son pocos los trabajos que han profundizado en el desarrollo y optimización de esta forma cualitativa de concordancia. El presente trabajo, además de constituirse en un ejemplo de la utilización de la concordancia por consenso, ha comparado el resultado obtenido (tiempo empleado y ajuste con el registro ideal) por grupos de consenso formados por diferente número de integrantes (dos, tres y cuatro observadores). No se han encontrado diferencias significativas al comparar los grupos de concordancia por consenso de dos, tres y cuatro integrantes, ni en relación al tiempo empleado en el registro, ni en lo relativo al porcentaje de acuerdo con el registro ideal. La determinación del tamaño muestral necesario para obtener diferencias significativas entre los grupos, ha permitido elevar conclusiones en términos de eficiencia. The reliability of datasets in observational methodology is typically tested using coefficients of agreement, correlation coefficients, or generalizability theory. Another increasingly popular method used to demonstrate the quality of data is the consensus agreement method, in which two or more observers agree on their coding decisions while creating the dataset. Although the consensus agreement method is being increasingly used in observational studies, few studies have conducted an in-depth analysis of how this qualitative procedure is approached or of how it can be optimized. In this study, in addition to presenting a practical example of the application of the consensus agreement method, we compare the results from three groups (of two, three, and four observers) to analyze performance in terms of time required to code the data and goodness of fit with respect to an optimal dataset. No significant differences were found between the three groups for either of the variables analyzed. Prior calculation of the sample size required to detect significant differences between the groups adds strength to our conclusions regarding the efficiency of the consensus agreement method. Na metodologia observacional, para lidar com a confiabilidade de dois dados já registrados, costumamos passar pelos coeficientes de concordância, coeficientes de correlação ou pela teoria da generalização. Além disso, a concordância consensual vem ganhando cada vez mais destaque. Esta forma de concordância tenta chegar a um acordo entre os observadores antes do registro. Apesar de sua crescente presença em estudos observacionais, poucos estudos se aprofundam no desenvolvimento e otimização de uma forma qualitativa de concordância. Ou apresentar trabalho, além de ser um exemplo do uso de concordância de consenso, comparação ou resultado obtido (tempo despendido e ajuste como registro ideal) por grupos de consenso formados por diferentes números de membros (dois, três e quatro observadores). Não foram encontradas diferenças significativas na comparação de dois grupos de concordância por consenso de dois, três e quatro membros, não em relação ao tempo gasto não registrado, mas em relação ao percentual de concordância conforme lista ideal. A determinação do tamanho dá a amostra necessária para obter diferenças significativas entre os grupos, permitindo-nos tirar conclusões em termos de eficiência.
