Resumen
La presente investigación tuvo como objetivo evaluar el efecto placebo sobre el tiempo de reacción durante la arrancada en los 100 metros planos. La muestra la integraron 128 de estudiantes de 1ro año y 2do año de la Universidad Central “Marta Abreu” de Las Villas, que fueron distribuidos aleatoriamente en cuatro grupos: enjuague bucal con agua (n = 30); enjuague bucal con Remedios Florales
de Bach (BFR: n = 33); imaginarse como un resorte contraído (n = 31) y línea base o control (n = 34).
Previo al experimento se evaluaron tanto las expectativas de los participantes como la motivación por participar en el estudio. Luego, cada participante realizó un total de cinco arrancadas. El tiempo y los errores de reacción se determinaron mediante procesamiento digital de imágenes.
De forma general, los rituales que utilizan sustancias inertes como el agua o los BFRs no parecen contribuir sustancialmente a la mejora del tiempo de reacción y los errores de anticipación en corredores de 100 metros planos. Por otro lado los resultados parecen sugerir que visualizarse como un resorte contraído puede contribuir sustancialmente a la reducción del tiempo de reacción una vez que el
recurso se ha incorporado como un hábito a través del entrenamiento, especialmente durante la primera arrancada. Sobre todo si el participante se encuentra altamente motivado por el resultado.
The objective of the current investigation is to evaluate the placebo effect on reaction time in the 100 meter track and field start. The sample consisted of 128 first and second year students from the Central University ¨Marta Abreu¨ of the Las villas, whom were randomly distributed in four groups: those whom gargled with water (n =30); those whom gargled with Bach Floral Remedies (BFR: n = 33); those whom imagined to be a contracted spring (n = 31) and those whom formed the control group (n = 34). Prior to the experiment the participants’ expectations and motivation to participate in the experiment were evaluated. After, each participant performed five starts. The reaction time and reaction errors were determined using digital image processing. Generally, the rituals that utilize inert substances such as water or BFRs did not seem to contribute substantially in improving the reaction time and anticipation errors in the 100 meter runners. On the other hand the results seem to suggest that selfvisualizing as a contracted spring may contribute substantially in reducing the reaction time once the resource has been incorporated as a training habit, especially during the first start. More so if the participant appears to be highly motivated to achieve their goal. .
