Análisis de la fiabilidad test-retest de un protocolo incremental para la obtención de la 1 repetición máxima, fuerza pico y potenica media en el tren superior en futbolistas

Resum

Introduction: The team sports are characterized by short periods of preparation and competitive long periods. Keep a tight check and with scientific rigor is no easy task. In this experience it was to perform both. Although different protocols were made to determine the fitness or operational status of our players, here is going to present the results in an upper body exercise. Objective: The purpose of this research was to analyze the reliability (test-retest) of a protocol incremental loads up to the 1RM in the bench press exercise in Smith machine. We also analyzed the stability or range of reliability of the average power and peak force. Method: This protocol incremental load strength testing (+10 kg> 0.5 m rep.) Was conducted in twice with a minimum recovery time of 72 hours. All players were instructed to move the load at maximum speed in each attempt. The test ended when subjects reached their 1RM (0.16 ± 0.4 m � s-1). Twelve third division footballers participated voluntarily in this study (mean and standard deviation of height, weight and age: 180.8 ± 5.6 cm, 72.4 ± 5.72 kg, 24.4 ± 5.72 years, respectively). For the analysis of test-retest reliability index was used intraclass correlation (ICC2, 1), the standard error of measurement (SEM) and minimal differences (MD). Results: The results in terms of the maximum load shifted 1RM shows high testretest reliability (ICC = 0.96, SEM = 3.56 kg MD = 9.8 kg). Peak force has a test-retest fiablili moderately high (ICC = 0.76 to 0.96 range, range = 33.5-39.6 N SEM and range Movimiento humano 4/2012, 25-35. ISSN: 2014-3060 27 = 92.8-98.7 N MD) as the average power (range =.70 to.94 range ICC SEM and range = 12.5-24.9 W MD = 34.6-68.9 W). Conclusions: The incremental protocol used in the present investigation provides a reliable, the maximum offset load. Conducting tests allow test-retest �calibrate� loads properly after the results of the assessments to our athletes. The information it provides is very interesting and useful because it facilitates training areas to consider depending on the manifestation of the force wants to encourage between evaluation periods or re-calibration of the load. Using test-retest testing allows more accurately adjust loads over different planning periods.
