“…Sin embargo, la variable flexibilidad dinámica de cadera medida en este test de zancada si presentaba fiabilidad. Este salto es básico en gimnasia rítmica, siendo fundamental una buena apertura en esta posición para obtener buenos resultados deportivos (46,47) . Por tanto, la relevancia de la flexibilidad en su manifestación activa-balística en este tipo de salto coinciden con varios autores (48,49) .…”

Objetivo: La gimnasia rítmica implica la realización de gran numero de habilidades motoras que requieren capacidades específicas. El objetivo fue determinar la validez y fiabilidad test-retest de las 10 pruebas que componen la batería Funcional Aristo en Gimnasia Rítmica (BFAGR). Método: Participaron 51 gimnastas de nivel avanzado con edades entre 12 y 19 años. Se utilizó la razón de validez de contenido para calcular el Índice de Validez de contenido (RIVC) de la batería global evaluada por 16 expertos. Se aplicó el Coeficiente de Correlación Intraclase (CCI) para la confiabilidad inter-evaluadores y la fiabilidad test-retest con un intervalo de siete días. En caso de no cumplirse los supuestos de normalidad y homocedasticidad, se optó por el método de Bland y Altman para la estimación de la confiabilidad. Resultados: Los resultados muestran la validez de la BFAGR con un IVC global elevado de 0.81 La confiabilidad inter-evaluadores es alta presentando valores superiores a 0,99 en todas las pruebas. El CCI indicó muy buena reproducibilidad (> 0,90) en las pruebas “Spagat antero posterior a derecha”, “Elevación frontal de pierna derecha e izquierda y mantener”, Puente en spagat, “Zancada (flexibilidad dinámica)” y saltos dobles de comba. Igualmente, se presumió la presencia de concordancia a través del método Bland y Altman, en las pruebas “Spagat antero posterior a izquierda”. Conclusiones: Los cálculos de validez y confiabilidad, confirman que seis pruebas (dos bilaterales) de la BFAGR preliminar son adecuadas para la valoración de la condición física específica en gimnastas de estas edades.

Introduction: The physical health of children and adolescents is directly related to school physical training quality. The improvement of adult sports effectiveness results from a concise protocol with standardized exercises. Rope skipping exercise lacks kinematic studies applied to children and adolescents. Objective: Provide a theoretical reference for jump rope exercise training for children and adolescents. Methods: Eight children aged six to eight years old were recruited to jump at a frequency of 80 and 120 jumps per minute controlled by a metronome. The technique was divided into three stages: impulse, suspension, and landing. Control in the knee joint exoskeleton balance was investigated by computerized baropodometry with differentiation of rotational angular velocity by rotational angular acceleration via Butterworth filter. After noise cleaning and multiplication, an adjustable amplification factor returned to the inlet with inertial compensation torque. Results: Initially, the impulsing force is about three times the individual’s gravity. This value and the center of mass acceleration decrease in time. The initial force is proportional to the velocity of its decrease during the impulse, and the opposite occurs with the landing force. Higher intensity is observed when raising the frequency. Conclusion: The fluctuation in the force curve in the landing phase after 20 jumps indicates low muscle strength in lower limbs to maintain activity. A speed of 80 jumps per minute controlled by music in a playful environment is recommended for children. Evidence Level II; Therapeutic Studies – Investigating the results.

Introduction Aerobic gymnastics is an emerging sport. It develops mainly the aerobic body metabolism improving the cardiopulmonary function of the practitioner. Objective To analyze the influence of core strength training on the physical fitness of university athletes who practice aerobic gymnastics. Methods Using mathematical statistics, we studied the influence of aerobic exercise on the physical fitness of female college athletes. The fitness index test of female college aerobics athletes was performed with Excel 2007, and the obtained results were discussed. Results College female students showed significant improvement in somatization, interpersonal sensitivity, anxiety, and other four factors after aerobic gymnastics exercise (P<0.05). After the practice period, female college students improved orthostatic performance, long jump, stretching in sitting forward position, 1 minute sitting, running four times round trip for 10 meters, and 800 meters. The increase was 11.16cm, 5.02cm, 8.34 times/min, 2.13s, and 9.42s. Conclusion Core training in aerobic gymnastics can strengthen the body, allowing awareness of physical training in college women. Evidence Level II; Therapeutic Studies – Investigating the results.
