The perception of the physical education class by the students is an important factor because depending on how the students perceive these experiences, certain beliefs or evaluations will be generated, which influence the attitude to face these bodily experiences each time they To present themselves. 176 students (14.74 ± 0.68), belonging to private subsidized establishments in the Coronel commune. The objective of this research is to analyze the subjective attitudinal perception of secondary school students towards PE teachers. To evaluate the attitudinal perception of the students towards the physical education teacher, a modification of the questionnaire of attitudes of schoolchildren towards physical education was used. In the results of the positive attitudes, it can be indicated that the students valued the item "Strongly agree" more in the question "My physical education teacher knows a lot", in the negative attitudes the question "My physical education teacher physical education raises their voice frequently" was the highest percentage in the item "Strongly agree" . In the comparative analysis between men and women for the positive perception I report (p = 0.63) and negative (p = 0.10). In the analysis by age for the positive scale (p = 0.01), for the negative scale (p = 0.25). The students observed mostly positive attitudes and very few negative ones in the physical education teacher, without observing differences between men and women, in the ages differences were reported in the positive and negative attitudes of the teacher, informing that the students with more age more critically evaluate the positive and negative attitudes of the PE teacher., La percepción de la clase de educación física por parte de los estudiantes es un factor importante porque dependiendo de cómo los escolares perciban estas vivencias, se generarán determinadas creencias o valoraciones, las que influyen en la actitud para enfrentar estas experiencias corporales cada vez que se presenten. 176 estudiantes (14.74 ± 0.68), pertenecientes a los establecimientos particulares subvencionados de la comuna de Coronel. El objetivo de esta investigación es analizar la percepción actitudinal subjetiva de los estudiantes de enseñanza secundaria hacia los profesores de EF. Para evaluar la percepción actitudinal de los estudiantes hacia el profesor de educación física, se utilizó una modificación del cuestionario de actitudes de los escolares hacia la educación física. En los resultados de la actitudes positivas, se puede indicar que el alumnado valoro mayormente el ítem “Muy de acuerdo” en la pregunta “Mi profesor/a de educación física sabe mucho”, en las actitudes negativas la pregunta “Mi profesor/a de educación física levanta la voz frecuentemente” fue el mayor porcentaje en el ítem “Muy de acuerdo” . En el análisis comparativo entre hombres y mujeres para la percepción positiva reporto (p = 0.63) y negativa (p = 0.10). En el análisis por edades para la escala positiva (p = 0.01), para la escala negativa (p = 0.25). El alumnado observo mayormente actitudes positivas de y muy pocas negativas en el profesor de educación física, sin observase diferencias entre hombres y mujeres, en las edades se reportaron diferencias en las actitudes positivas y negativas del profesor, informando que los alumnos de con más edad evalúan más críticamente las actitudes positivas y negativas del profesor de EF.

This study aims to analyze the reliability of the test of 8 throws of 3 different variants of handball throws in university students. The participants were 33 males, 20 ± 1.9 years; weight 72.39 ± 8.9 kg; height 176.75 ± 6.07 cm; BMI 23.14 ± 2.3. They were evaluated in 2 sessions separated from each other by a period of one week. The participants executed throws until 8 measurements were recorded in each of the tests, unspecific throws, in support and in the race with 3 steps; the launch speed was recorded with a radar behind the goal. The reliability of the average of the test scores of 8 measurements between the first session and the second was measured with a test-retest test. The following results were obtained: in the nonspecific launch, an ICC= (0.86) was obtained between 95% of confidence, one of CV= (7.43%) and one ES = (0.08). For the toss with support, an ICC = (0.94) was obtained at 95% confidence, one of CV = (4.71%) and an ES = (-0.09). For the running throw, an ICC = (0.96) was obtained at 95% confidence, one of CV = (4.00%) and one ES = (0.05). This study has shown that the test of 8 throws and the 3 variants is a reliable and stable performance measure for university-level students without experience in handball; in relation to the throw variables, all 3 were reliable. Only the nonspecific variable was lower compared to the supported and running pitch., O estudo tem como objetivo analisar a confiabilidade do teste de 8 arremessos de 3 variantes diferentes de arremessos de handebol em estudantes universitários. 33 homens, 20 ±1,9 anos; peso 72,39±8,9 kg; altura 176,75 ±6,07 cm; IMC 23,14±2,3. Os participantes foram testados em 2 sessões separadas por um lapso de 1 semana. Os participantes executaram arremessos até poder registrar 8 medições em cada um dos testes, arremessos não específicos, com apoio e correndo com 3 passos. A velocidade de arremesso foi registrada com um radar pós-gol. A confiabilidade da média dos resultados dos testes de 8 medições entre a primeira sessão e a segunda com um teste de retorno, deu os seguintes resultados: no teste de lançamento não específico, foi obtido um ICC= (0,86) com 95% de confiança, um CV= (7,43%) e um ES= (0,08). Para o lançamento apoiado obtivemos um ICC= (0,94) a 95% de confiança, um CV= (4,71%) e um ES= (-0,09). Para o arremesso de corrida obtivemos um ICC= (0,96) a 95% de confiança, um CV= (4,00%) e um ES= (0,05). Este estudo mostrou que o teste de 8 lances e as 3 variantes é uma medida de desempenho confiável e estável para estudantes universitários sem experiência em handebol. Em relação às variáveis de arremesso, todas as 3 foram confiáveis, apenas a variável não específica foi menor em comparação com o arremesso com suporte e com corrida., El estudio tiene como propósito analizar la fiabilidad de la prueba de 8 lanzamientos de 3 diferentes variantes de lanzamientos de balonmano en estudiantado universitario. 33 varones, 20 ±1,9 años; peso 72,39±8,9 kg; altura 176,75 ±6,07 cm; IMC 23,14±2,3. Los sujetos participantes fueron evaluados en 2 sesiones separadas entre sí por un lapso de una semana. Ejecutaron lanzamientos hasta quedar registrados 8 mediciones en cada una de las pruebas, lanzamientos inespecíficos, en apoyo y en carrera con 3 pasos, se registró la velocidad de lanzamiento con un radar posterior a la portería. La fiabilidad del promedio de las puntuaciones del test de 8 medidas entre la primera sesión y la segunda con una prueba test-retest, se obtuvieron los siguientes resultados: en el lanzamiento inespecífico se obtuvo un ICC= (0,86) entre el 95% de confianza, un de CV= (7,43%) y un ES= (0,08). Para el lanzamiento con apoyo se obtuvo un ICC= (0,94) al 95 % de confianza, un de CV= (4,71 %) y un ES= (-0,09). Para el lanzamiento con carrera se obtuvo un ICC= (0,96) al 95 % de confianza, un de CV= (4,00 %) y un ES= (0,05). Este estudio ha demostrado que la prueba de 8 lanzamientos y las 3 variantes es una medida de rendimiento confiable y estable para estudiantes de nivel universitario sin experiencia en el balonmano, en relación con las variables del lanzamiento, las 3 fueron fiables, solo la variable inespecífica fue menor en comparación al lanzamiento con apoyo y con carrera.

Introduction: the regular practice of physical exercise is an important modulator of resting energy expenditure (REE), which depending on the intensity, duration, and type of exercise can increase the REE in an acute manner as well as long term. The effects of dynamic muscular strength exercises on the REE have been treated very little in literature. Objective: compare the effect of muscle strength exercise (MSE) at different intensities on the REE in young males. Methods: Intra-group design. Fourteen subjects aged 22,5±1,5 0,05) after the exercise at 40%RM. The REEpost 24h was maintained according to the REEpre when the intensity was 80%RM. Conclusion: The REEpost exercise is independent of the intensity of the exercise and only is maintained after 24 hours when the MSE is at a high intensity.
