The present study aimed to examine the effect of an 8-week balance training on the agility, strength, balance performance and tennis skills of tennis players aged 10-14. The study was participated by 19 tennis players (10 males and 9 females) playing in the EA Tennis Academy. The participants were selected randomly and divided into two groups as experimental group (9 players) and the control groups (10 players). Firstly, vertical jump, pro-agility, dynamic balance and ITN tennis skills tests were applied to all the participants. After all the test were completed, the experimental group were applied 8 weeks of balance and tennis training while the players in the control group continued tennis training only. The same tests were applied to the participants at the end of the 8 weeks. The findings of the study showed statistically significant improvement in the agility, balance index and tennis skills tests in the pre-test and post-tests of the experimental group (p = 0.034, p = 0.025, p = 0.003), whereas improvement was seen only in the tennis skills test of the control group (p = 0.000). In addition, no statistically significant difference was found in the vertical jump performance used to determine the explosive strength both in the experimental and control groups. As for the difference between groups, a significant difference was found only in the pro-agility post-tests of the experimental and control groups (p < 0.05). Based on these findings, it was revealed that balance training would improve agility and balance in 10-14 year-old children as well as contributing to their tennis skills. Therefore, it is considered that balance training should be included in training plans.

  En los últimos años es frecuente la impartición de la educación física (EF) en lengua inglesa, lo que puede influir sobre las percepciones que los alumnos[1] tienen sobre dicha asignatura. En el presente estudio se analizó el efecto de una metodología bilingüe, el code-switching, sobre la percepción de la comunicación docente y la motivación. La muestra estuvo compuesta por 94 estudiantes de entre 12 y 14 años (M= 13.76; DT=.86). El grupo experimental (n=46) estuvo formado por dos grupos pertenecientes a formas diferentes de implantación del bilingüismo (programa y sección) y el grupo control (n= 47) por dos grupos equivalentes a los anteriores. Previo a la intervención, se realizaron entrevistas a profesorado de EF; los cuestionarios pre y post fueron administrados al alumnado al inicio y al fin de la misma. Tras la intervención se hallaron diferencias en la motivación intrínseca de uno de los grupos experimentales. Los resultados sugieren que la percepción de la comunicación docente por parte de los alumnos no difiere en función de que la clase se imparta íntegramente en inglés o utilizando el code-switching. Se discuten las implicaciones educativas de estos hallazgos.  Abstract. Over the last few years, the teaching of PE in English language has become frequent which could influence the perceptions that students have about this subject. In the present study the effect of a bilingual methodology, code-switching, on perceptions of teaching communication and motivation was analyzed. The sample was composed by 94 students aging from 12 to 14 (M=13,76; SD= .86). Experimental group (n=46) was formed by two classes with different bilingual programs (programa and sección) and control group (n=47), by other two equivalent groups. After the intervention significant differences in intrinsic motivation were found in one of the experimental groups. The findings suggest that the perceptions of teaching communication do not differ between students taught completely in English and students taught through code-switching. Educational implications of these findings are discussed.

 The purpose of the study was to identify statistically significant differences in shifts in the indicators of the special working capacity of qualified Muay-Thai athletes in the experimental and control groups of different weight categories during performance of striking techniques using specialised tests. The data from special and scientific literature was considered. A practical experiment was carried out using the Hykso portable strain gauge diagnostic tool. The method of mathematical statistics was used. Forty-five qualified athletes took part in the experiment, twenty-three of whom were included in the experimental group, twenty-two – in the control group, both with and without weight categories. The shifts in the growth of the speed and strength potential of the athletes from the experimental group in comparison with the athletes from the control group of the lightweight category was identified. They are noted in three types of specialised tests of anaerobic capabilities with creatine-phosphate and glycolytic mechanisms of energy supply, in the form of speed and strength components, each separately. The effectiveness of differentiated programs with the use of the Podhurskyi's weight modified sports equipment for the improvement and implementation of speed-strength capabilities of qualified Muay-Thai athletes of different weight categories was established.  Resumen.

Ensayo Clínico

Objetivo: Describir el efecto de una dosis de ejercicio gradual y progresiva de bajo impacto cardiovascular sobre el autoconcepto físico en un grupo de adultos mayores.Métodos: Ensayo Clínico Aleatorizado y Controlado con intervención simple ciego en dos grupos equivalentes (experimental y control), bajo un modelo de mediciones repetidas. La muestra estuvo compuesta por 20 sujetos por grupo. Se seleccionaron adultos mayores de 60 a 70 años, de ambos sexos, sin riesgo cardiaco; se excluyeron adultos mayores con patologías que pudieran causar limitaciones en la funcionalidad músculo-esquelética o cardiopulmonar. La intervención consistió en la realización de ejercicio de forma gradual y progresiva, 3 veces por semana durante 10 semanas. El indicador para evaluar el autoconcepto físico fue el Instrumento de Auto descripción (SDQ), con un patrón de respuesta tipo Likert.Resultados: Ingresaron 45 sujetos, grupo control 22 adultos (edad 66.6±6.14) y grupo experimental 23 adultos (edad 67.0±7.19); completaron el programa 38 adultos. En ambos grupos predominaron las mujeres (66.7%), nivel socioeconómico medio (73.3%) y escolaridad básica (44.6%). No existió diferencia significativa entre los grupos antes de la intervención, en contraste, después de la intervención existió diferencia significativa entre grupos, lo que resultó en un incremento del autoconcepto físico en el grupo experimental y un descenso del autoconcepto físico en el grupo control.Conclusión: La intervención de ejercicio controlado, gradual, progresivo y de bajo impacto cardiovascular, de tres sesiones por semana durante 10 semanas probó ser efectiva para aumentar el autoconcepto físico en el grupo experimental de adultos. Objective: To describe the effect of a dose of gradual and progressive exercise of low cardiovascular impact on physical self- concept in a group of seniors. Methods: Randomized, controlled clinical trial with a blinded experiment in two equivalent groups (experimental one and control one), under a repeated model of measures. The sample consisted of 20 individuals per group. Male and female seniors from 60 to 70 years old with no heart risk, were selected. Seniors with pathologies that could cause limitations on the musculoskeletal function cardiopulmonary functionality were excluded. The intervention consisted of performing exercise gradually and progressively, 3 times a week for 10 weeks. The indicator for assessing physical self-concept was the Self-Description Questionnaire (SDQ), with a Likert response pattern.Results: 45 individuals were taken; control group 22 adults (age 66.6 ± 6.14) and experimental group 23 adults (age 67.0 ± 7.19); 38 adults completed the program. In both groups, women predominated (66.7%), medium socioeconomic level (73.3%) and basic schooling (44.6%). There was no significant difference between the groups before the intervention, in contrast, after the intervention there was a significant difference between them, which resulted in an increase in physical self-concept in the experimental group and a decrease in physical self-concept in the control group.Conclusion: The intervention of controlled, gradual, progressive and low cardiovascular impact exercise of three sessions per week for 10 weeks proved to be effective in increasing physical self-concept in the experimental group of adults.
