There were significant group x time interactions for vBla4 (P = 0.0235), CMJ (P = 0.0234), SJ (P = 0.0168), and 5-km running time trial performance (P = 0.0035).

Abstract

The aim of this 4-armed parallel group randomized-controlled trial was to evaluate if plyometric training could have different effects on running performance and physiological adaptations depending on the training intensity distribution (TID) in an 8-week intervention in endurance athletes. Sixty well-trained male runners (age: 34 ± 6 years, relative ⩒O2peak: 69 ± 3 mL·kg-1·min-1) were recruited and allocated to a pyramidal (PYR), pyramidal + plyometric training (PYR+PLY), polarized (POL), and polarized + plyometric training (POL+PLY) periodization. The periodization patterns were isolated manipulations of TID, while training load was kept constant. Participants were tested pre- and post-intervention for body mass, velocity at 2 and 4 mmol·L-1 of blood lactate concentration (vBLa2, vBLa4), absolute and relative ⩒O2peak and 5-km running time trial performance, counter movement jump and squat jump. There were significant group x time interactions for vBla4 (P = 0.0235), CMJ (P = 0.0234), SJ (P = 0.0168), and 5-km running time trial performance (P = 0.0035). Specifically, vBla4 and 5-km running time trial performance showed the largest post-intervention improvements in PYR+PLY (2.4% and 1.6%) and POL+PLY (2.1% and 1.8%), respectively. No significant interactions were observed for body mass, absolute and relative ⩒O2peak, peak heart rate, lactate peak and rating of perceived exertion. In conclusion, an 8-week training periodization seems to be effective in improving performance of well-trained endurance runners. Including plyometric training once a week appeared to be more efficacious in maximizing running performance improvements, independently from the TID adopted.
