AB Objective. — To determine the muscle architecture adaptations in the vastus lateralis (VL) andvastus medialis (VM) after an eccentric training programme based on the Reverse Nordic Ham-string Exercise (RNHE) and after a subsequent detraining period.Subjects and methods. — The participants (N = 28) underwent a 12-week intervention, consistingof one week of assessment and familiarisation, followed by seven weeks of eccentric trainingand four weeks of detraining. The VL and VM muscle architecture features were assessed inresting conditions by means of 2D ultrasonography before (week 1) and after (week 8) thetraining period, as well as after the detraining period (week 12).Results. — Significant increases in the VL and VM muscle fascicle length (FL) (t = − 5.06, d = 1.43,P < 0.05 and t = − 11.14, d = 3.09, P < 0.001, respectively), muscle thickness (MT) (t = − 5.0,d = 1.39, P < 0.05 and t = − 6.17, d = 1.71, P < 0.05) and pennation angle (PA) (t = − 6.77, d = 1.88,P < 0.05 and t = − 4.48, d = 1.25, P < 0.05) were observed after the training period.
