Changes in Recovery-Stress State and Performance in Elite Rowers during Preparation for Major Competitions

Abstract

This study investigated changes in the perceived recovery-stress state and performance in 6 highly trained Estonian rowers preparing for major competitions and representing Estonia in double sculls (age: M = 23.0, SD = 1.4 yr.; height: M = 198.0, SD = 0.0 cm; body mass: M = 97.1, SD = 6.4 kg), and quadruple sculls (age: M = 21.5, SD = 2.5 yr.; height: M = 189.5, SD = 5.4 cm; body mass: M = 90.9, SD = 4.8 kg). The subjects were training regularly and had been doing so for the last 10.5 yr. (double scullers, SD = 2.1 yr.) and 7.5 yr. (quadruple scullers, SD = 3.1 yr.), respectively. The Recovery-Stress Questionnaire for Athletes of Kellmann and Kallus was given two days before World Cup competitions. Standardized Stress and Standardized Recovery scores and RESTQ-Index were computed. In addition, resting Cortisol in blood was measured at the same time. The performance of both boat classes constantly decreased from World Cup 1 to World Cup 3 as indicated by percent losses for winning boats. Resting Cortisol and RESTQ-Index increased and decreased, respectively, at the same time. For double scullers, a decrease in RESTQ-Index mainly reflected the large decrease in the Standardized Recovery score. A decrease in RESTQ-Index was mainly based on a large increase in the Standardized Stress score for rowers performing in a quadruple scull. Present results indicate that the recovery-stress state affects performance of rowers in international competitions. RESTQ-Index could be used as the athletes' resource measure, while the Standardized Stress and Standardized Recovery scores reflect the athletes' extent of stress and recovery separately.
