The training-specific adaptations resulting from resistance training, gymnastics and plyometric training, and non-training in adolescent athletes
(Die trainingsspezifischen Anpassungen, die sich aus dem Krafttraining, der Gymnastik, dem plyometrischen Training und dem "Nichttraining" bei jugendlichen Sportlern ergeben)
Although previous research has investigated the training-specific adaptations to training in adults, there is a paucity of research aimed at investigating these adaptations in adolescent athletes. As such, adolescent athletes training-specific adaptations from three different training intervention...s were investigated in this study. Sixteen adolescent athletes participated in this study, whereby eight performed both training interventions and eight the non-training control. Pre- and post-testing was performed for each intervention with the testing battery: ultrasonography of the vastus lateralis and lateral gastrocnemius, countermovement jump, squat jump, and isometric mid-thigh pull. The resistance training group had large significant increases in isometric mid-thigh pull relative peak force (p<0.01, g=0.85 (-0.01, 1.71)) and vastus lateralis fascicle length (p=0.04, g=0.94 (0.07, 1.80)). The gymnastics and plyometric group demonstrated large significant changes in vastus lateralis pennation angle (p=0.03, g=-0.94 (-1.81, -0.08)) and fascicle length (p=0.03, g=1.07 (0.19, 1.95)), and moderate significant increases in lateral gastrocnemius thickness (p=0.01, g=0.63 (-0.21, 1.47)) and eccentric leg stiffness (p=0.03, g=0.60 (-0.24, 1.44)). No significant changes were observed for any variables in the non-training group. The resistance training evoked increases in lower-body force producing capabilities, whereas the gymnastics and plyometric training evoked changes in muscle structure and inherent muscle qualities.
