Changes in the mechanical characteristics of the knee musculature in professional female volleyball players

The technical efficiency in volleyball is closely related to the ability to perform displacements or jump (1). Therefore, it is necessary that precise, individualized, and localized evaluation of the muscles frequently involved in volleyball practice be studied (2,3). The aim of this study was to analyze the neuromuscular changes of the knee musculature in professional volleyball players using Tensiomyography (TMG) and jump tests.

Muscle function and body composition profile in adolescents withrestrictive anorexia nervosa: Does resistance training help?

The aim of this study was to analyze the effects of short-term resistance training on the body composition profile and muscle function in a group of Anorexia Nervosa restricting type (AN-R) patients. The sample consisted of AN-R female adolescents (12.8 ± 0.6 years) allocated into the control and intervention groups (n¼18 each). Body composition and relative strength were assessed at baseline, after 8 weeks and 4 weeks following the intervention. Body mass index (BMI) increased throughout the study (p = 0.011). Significant skeletal muscle mass (SMM) gains were found in the intervention group (p = 0.045, d = 0.6) that correlated to the change in BMI (r = 0.51, p < 0.031). Meanwhile, fat mass (FM) gains were significant in the control group (p = 0.047, d = 0.6) and correlated (r > 0.60) with change in BMI in both the groups. Significant relative strength increases (p < 0.001) were found in the intervention group and were sustained over time.

Aprendizaje experiencial aplicado en la enseñanza superior en el campo de la electrónica en cursos para adultos trabajadores

En este trabajo se muestran las experiencias tenidas con adultos trabajadores en la enseñanza de la Electrónica, en la formación de los mismos como Ingenieros. Están basadas en el aprendizaje experiencial, desde el primer encuentro, gracias a las vivencias obtenidas por el propio alumno, se aprecian ventajas en la aplicación de esta metodología que dan respuesta a las necesidades de este tipo de alumno. Así estos alumnos optimizan el tiempo necesario de aprendizaje, facilitando la comprensión, aplicación y justificación de los conocimientos teóricos. Les reafirma la confianza en sí mismos y les facilita el acercamiento con su vida profesional.
