Abstract

Whole Body Vibration training is studied and used in different areas, related to sport performan ce and rehabilitation. However, few studies have investigated the effects of Vibration (Vib) exposure on aerobic performance through the application of this concept to cycling exercise. A specifically designed vibrat- ing cycloergometer, the powerBIKE TM , was used to compare the effects of Vib cycling exer cise and normal cycling on dif- ferent physiological parameters during maximal graded exer- cise test. Twelve recreationally active male adults (25 ± 4.8 yrs; 181.33 ± 5.47 cm; 80.66 ± 11.91 kg) performed two maximal incremental cycling tests with and without Vib in a block- randomized order. The protocol consisted of a 4 min warm up at 70 rev·min -1 followed by incremental steps of 3 min each. Cycling cadence was increased at each step by 10 rev·min -1 until participants reached their volitional exhaustion. Respira- tory gases (VO 2 , VCO 2 ), Heart Rate, Blood Lactate and RPE were collected during the test. Paired t-tests and Correlation Coefficients were used for statistical analysis. A significantly greater (P<0.05) response in the VO 2 , HR, BLa and RPE was observed during the Vib trial compare to normal cycling. No significant differences were found in the maximal aerobic power (Vib 34.32 ± 9.70 ml·kg -1 ·min -1 ; no Vib 40.11 ± 9.49 ml·kg -1 ·min -1 ). Adding Vib to cycling exercise seems eliciting a quicker energetic demand durin g maximal exerci se. However, mechanical limitations of the vibrating prototype could have affected the final outcomes. Future studies with more compara- tive setting are recommended to d eeply appraise this concept.
