abstract="Vibrations experienced by cyclists can affect their performance and health. We analysed the vibrations transmitted by mountain bike (26 or 29-inch wheels), in a 2,110 m circuit with a sample of 55 cyclists. The results indicate that the 29&quot;-wheel increases speed (p < 0.001) and thus performance but it also increases exposure to vibrations as the root mean square (RMS) indicate (p = 0.001). The wheel diameter significantly affected the accelerometer-related dependent variables (p < 0.01), specifically seen in the RMS variable (p < 0.01). Regarding vibration transmission variables, it was found that the LW/FH, RW/FH, LA/RH, and RA/RH ratios were higher in the 29&quot; bicycle than in 26&quot; one. Average heart rate (p = 0.01) and maximum heart rate (p < 0.01) values were higher for the 29&quot; bike with no significant differences in the average power values recorded. In conclusion, bicycles with 29&quot; wheels transmit higher levels of vibration to riders.<p /> <p>Language: en</p>",
