Purpose:
The aim of the study was to evaluate the changes in upper and lower extremity kinaesthesia during a motorcycle season in recreational riders.

Methods:
The study involved 22 physically active and healthy males (age: 22.65 ± 2.33 years, body height: 180.35 ± 2.89 cm, body mass: 78.15 ± 2.89 kg): 11 street motorcyclists (5.80 ± 2.60 years of motorcycle riding experience, 8400.00 ± 450.00 km per year) and 11 individuals with no history of motorcycle riding (control group). The upper and lower extremities kinaesthesia was measured by a force-matching task replicating a handlebar and gear shift/rear brake dynamics of a motorcycle on a custom-designed kinaesthesiometer. The participants performed 10 right and left single-arm flexions and extensions and 10 right and left leg extensions at a force perceived to be equal to 98 N. The force production accuracy (FPA) for each movement was then calculated. The testing was performed before the start of the motorcycle season (beginning of March) and 4 months into the riding season (end of June).

Results:
No significant between-group or within-group differences were observed for FPA at any time point.

Conclusions:
The frequent upper and lower limb movements performed by motorcyclists during 4 months of motorcycle riding may be insufficient to induce changes in FPA. Future research should include a larger sample of motorcyclists to confirm the role of kinaesthesia in this population.
