Abstract

Abstract : Abstract: Sanz-López, F, Martínez-Amat, A, Hita-Contreras, F, Valero-Campo, C, and Berzosa, C. Thermographic assessment of eccentric overload training within three days of a running session. J Strength Cond Res 30(2): 504–511, 2016—The aim of this study was to analyze the changes in patellar and Achilles tendons between a group trained using eccentric overload and an untrained group within 3 days of a running session. To this end, infrared thermography (IRT) will be used. Twenty healthy male subjects were divided into 2 groups. One group performed a 6-week squat training in the flywheel before the running session. During the running intervention, both groups ran in 3 different days, for 1 hour each, at 80% maximal heart rate. Before, just after, and after 10 minutes of the running intervention, participants were assessed using IRT. Eccentrically trained groups showed a statistically significant difference (analysis of variance, p = 0.0049) expressed as a smaller bilateral increase in temperature in the patellar tendon just before the first running day (right side, 0.11° C; left side, 0.29° C). On the other days of running and in the Achilles tendon groups, similar changes were observed: an increase in the temperature after running and no significant difference between contralateral limbs. Our results point at eccentric overload training providing a better adaptation for the first day of running. IRT is an easy-to-apply noninvasive tool to analyze and compare the effects of performance on tendon tissues.
