ABSTRACT
RESUMEN En las últimas décadas, se han incorporado a los programas de entrenamiento ejercicios con la utilización de tubos (redondos) o bandas (planas) elásticas, de resistencia progresiva, lo que constituye una herramienta fundamental para desarrollar la fuerza muscular e imitar movimientos o gestos deportivos en numerosas especialidades deportivas, debido a su facilidad de uso. El objetivo del presente estudio fue diseñar un programa de entrenamiento con bandas elásticas de resistencia para el incremento de la velocidad, en la carrera home-primera base, con jugadores de la categoría juvenil de Matanzas que participaron en el XLVI Campeonato Nacional de Béisbol. La etapa experimental se desarrolla durante el periodo preparatorio, que constó de 20 microciclos de duración, con una frecuencia de tres días por semana, utilizando la combinación de ejercicios de velocidad con bandas o tubos elásticos y los modelos de periodización de la fuerza y el Sistema de Bloque o Fuerza Concentrada. Los resultados demuestran cambios significativos en los tiempos de la carrera home-primera base de los jugadores, en los diferentes controles efectuados para un 95 % de confianza, pues el valor de la probabilidad (p-value=0.0001) es menor que 0.05. Además, se alcanza un 4.37 % de incremento, con una reducción de los tiempos de 0.37 segundos.
ABSTRACT In the last decades, exercises with the use of tubes (round) or elastic bands (flat) of progressive resistance have been incorporated into the training programs, being a fundamental tool to develop muscle strength and imitate sport movements or gestures in numerous sports specialties, because of its ease to be used. The objective of this study was to design a training program with elastic resistance bands for the increase of the speed in the home-first base race with junior baseball players from Matanzas who participated in the XLVI National Baseball Championship. The experimental stage is developed during the preparatory period, which had a duration of 20 micro cycles, with a frequency of three days per week, using the combination of speed exercises with bands or elastic tubes and the models of periodization of strength and the System of Block or Concentrated Strength. The results show significant changes in the times of the home-first base race of the players in the different controls carried out with a 95% of confidence, since the value of the probability (p-value=0.0001) is less than 0.05. In addition, a 4.37 % increase was achieved with a reduction of 0.37 seconds.
ABSTRACT
Objective To explore the effect of progressive strength training with TheraBand on lower limb motor function and gait after stroke.Methods Forty-eight hemiplegic stroke survivors were randomly divided into a treatment group and a control group,each of 24.The patients of both groups were provided with the routine rehabilitation training,while the treatment group additionally trained the muscles of the paretic side progressively using Thera-Band elastic belts.Before and after 8 weeks of treatment,both groups were evaluated using the Fugl-Meyer movement assessment (FMA),the Berg balance scale (BBS),and the walking and stair negotiation components of the functional independence measure (FIM).GaitWatch gait analysis was also performed.Results After the treatment,significant improvement was observed with both groups' average FMA scores,BBS ratings,FIM scores,stride frequency,stride length and walking speed,but the treatment group showed significantly greater improvement than the control group,on average.Conclusion Using Thera-Band elastic belts to provide resistance can supplement routine rehabilitation training in improving motor function and walking ability after a stroke.
ABSTRACT
@#Objective To explore the rehabilitation effect of the Thera-Band Systems of progressive exercise on chronic lumbar back pain of the athletes.Methods 45 athletes with the soft tissue lesion were tested for pain and the function of lumbar back muscle was evaluated. Then all cases were trained with Thera-Band Systems.Results After training, the scores of pain and function evaluation of lumbar back muscle decreased significantly.Conclusion Thera-Band Systems of progressive exercise has the obvious and positive effects on chronic lumbar back pain and muscular proprioception of the athletes.
