Kinetic responses to external cues are specific to both the type of cue and type of exercise in adolescent athletes

Abstract

The purpose of this study was to examine how external cues influence kinetics during isometric and dynamic tasks in adolescent athletes. Fifteen adolescent male soccer players performed an isometric midthigh pull (IMTP), unloaded and loaded squat jumps (SJs) (15 and 30% of body mass), countermovement jump (CMJ), and drop jump (DJ) using a neutral or external force-specific or velocity-specific cues. Cue type had limited effects on outcomes in the IMTP or SJs, with mostly trivial (g < 0.20), nonsignificant differences (p > 0.05) across kinetic variables. In the CMJ and DJ, a force cue significantly (p < 0.05) increased jump height (g = 0.43 & 0.52) compared with a velocity cue, but in the DJ, a force cue significantly increased jump height (g = 0.52) compared with both a neutral and velocity cue. However, a velocity cue significantly (p < 0.05) reduced ground contact time (g = 0.73–1.52) and time to peak force (g = 0.50–1.29) in both the CMJ and DJ when compared with a force and neutral cue and increased force and power-related measures (g = 0.33–1.12) in the CMJ and DJ when compared with a force cue. In adolescent athletes, the type of external cue had limited effects on kinetic measures in an IMTP and SJ but differential effects on both a CMJ and DJ, suggesting cues have more effect with increasing movement velocity. Consequently, practitioners working with adolescent athletes should consider both the type of exercise and the desired outcome when providing external cues.
