Kinematic Variations Of Uphill In Mountain Bikers

The purpose of this study was to determine the relevant kinematic indicators between Elite and Under-23 categories of cross country mountain bike (MTB) cyclists in the climbing technique. The sample was made up of Under-23 (n=5; 18.8 +/- 0.5 years) and Elite (n=7; 24.2 +/- 2.0 years) cyclists, all male and right-handed, federated participants of cross-country MTB competitions.The data were recorded from the sagittal plane to the ascending one through a terrain with a slope of 9.5 +/- 0.5% with videophotogrammetry.The indicators that showed differences between categories were: left pedaling cycle angular velocity (p=0.04; g=-1.22), left pedaling cycle time (p=0.02; g=1.44), left pedaling cycle angular velocity of the preparatory phase (p=0.03; g=-1.37), while for joint speed; speed of the left hip in clean and jerk phase (p=0.029; g =-1.38), speed of the left ankle (p=0.005; g=-1.94) and right ankle (p=0.002; g=-2.17) in recovery phase.
