The main purpose of the present study was to examine the effects of acute whole body vibration (WBV) on recovery following a 3 km time trial (3 km TT) and high-intensity interval training (HIIT) (8 x 400 m). Post-HIIT measures included 3 km time-trial performance, exercise metabolism and markers of muscle damage (creatine kinase, CK) and inflammation (c-reactive protein, CRP). A second purpose was to determine the effects of a 3 km TT and HIIT on performance and metabolism the following day. Nine well-trained, middle-aged, male runners [(mean +/- SD) age 45 +/- 6 years, body mass 75 +/- 7 kg, VO2peak 58 +/- 5 ml kg(-1 )min(-1)] performed a constant pace run at 60 and 80% velocity at VO2peak (v VO2peak) followed by a 3-km TT and a 8 x 400-m HIIT session on two occasions. Following one occasion, the athletes performed 2 x 15 min of low frequency (12 Hz) WBV, whilst the other occasion was a non-WBV control. Twenty-four hours after each HIIT session (day 2) participants performed the constant pace run (60 and 80% v VO2peak) and 3 km TT again. There was a significant decrease in 3 km TT performance (~10 s) 24 h after the HIIT session (P < 0.05); however, there were no differences between conditions (control vs. vibration, P > 0.05). Creatine kinase was significantly elevated on day 2, though there were no differences between conditions (P > 0.05). VO2peak and blood lactate were lower on day 2 (P < 0.05), again with no differences between conditions (P > 0.05). These results show no benefit of WBV on running performance recovery following a HIIT session. However, we have shown that there may be acute alterations in metabolism 24 h following such a running session in well-trained, middle-aged runners.
