Description
Fifteen highly trained distance runners (V̇O2max 71.1 ± 6.0 ml·min-1·kg-1, mean ± SD) were randomly assigned to a plyometric training (PLY; n = 7) or control (CON; n = 8) group. In addition to their normal training, the PLY group undertook 3 X 30 minutes PLY sessions per week for 9 weeks. Running economy (RE) was assessed during 3 X 4 minute treadmill runs (14, 16, and 18 km·h-1), followed by an incremental test to measure V̇O2max. Muscle power characteristics were assessed on a portable, unidirectional ground reaction force plate. Compared with CON, PLY improved RE at 18 km·h-1 (4.1%, p = 0.02), but not at 14 or 16 km·h-1. This was accompanied by trends for increased average power during a 5-jump plyometric test (15%, p = 0.11), a shorter time to reach maximal dynamic strength during a strength quality assessment test (14%, p = 0.09), and a lower V̇O2-speed slope (14%, p = 0.12) after 9 weeks of PLY. There were no significant differences in cardiorespiratory measures or V̇O2max as a result of PLY. In a group of highly-trained distance runners, 9 weeks of PLY improved RE, with likely mechanisms residing in the muscle, or alternatively by improving running mechanics. © 2006 National Strength & Conditioning Association.
