The vertical treadmill (VertiRun, UK) is an unresearched mode of exercise where users engage in a "running-like" action whilst body weight is supported by a recumbent bench and overhanging resistance cables are tethered to the user's ankles. The purpose of this study was to determine the effects of training on a VertiRun and any cross-training effect on running performance. Thirty active males (age 22 ± 4 years, stature 1.79 ± 0.08 m, mass 78.5 ± 12.6 kg) volunteered for this study. Participants' aerobic and anaerobic running performance were determined by incremental VO2max treadmill test and a maximum anaerobic running test (MART), respectively. Participants were matched and then randomly assigned to either a VertiRun group, 20 m shuttle sprint group or control group. The intervention consisted of 4-6, 30 s all-out efforts with 4 minutes recovery between bouts, 3 days a week for 6 weeks. The pre and post intervention VO2max and MART were analysed using a mixed repeated measures ANOVA. MART increased by 4.5% in the VertiRun group (P=0.006) and 4% in the sprint group (P<0.001). VO2max increased by 6.2% in the VertiRun group (P=0.009) and 5.5% in the sprint group (P=0.020). The MART and VO2max of the control group were unchanged (P=0.910 and P=0.915, respectively). These data suggest that the VertiRun could be an effective cross-training mode for running and could supplement training programmes. Also, as VertiRun is a low-impact exercise it might be useful in the physical preparation of athletes returning to sport following lower limb injury.
