METHODS: Cohort study. One hundred and twenty-one road cyclists volunteered to participate. ROM measurements of passive hip flexion, extension, internal rotation, external rotation, knee flexion and ankle dorsiflexion in dominant and non-dominant limbs were performed using an inclinometer. ROM scores were individually categorized as normal or restricted according to reference values. RESULTS: Overall, hip flexion was smaller in the non-dominant limb than in the dominant limb (F=12.429, P<0.001), with bilateral differences in male (95% mean diff: 0.5° to 3.3°) and female cyclists (95% mean diff: 0.1° to 3.1°). Sex differences were found in hip flexion (F=18.346, P<0.001), hip internal rotation (F=6.030, P=0.016) and ankle dorsiflexion (F=4.363, P=0.039), with males showing smaller ROM than females. Males and females had restricted knee flexion in dominant (males: 51.6%; females: 42.6%) and non-dominant limbs (males: 45.0%; females: 39.3%). Ankle dorsiflexion was also restricted in dominant (males: 38.3%; females: 31.1%) and non-dominant limbs (males: 41.6%; females: 34.4%). CONCLUSIONS: Elite road cyclists showed restricted lower-limb ROM according to reference values. In general, male cyclists showed lower values of ROM than females’ counterparts. These findings suggest that including specific stretching exercises and resistance training to improve knee and ankle dorsiflexion ROM may prevent muscle imbalances caused by chronic pedaling in professional cyclists.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Physical examinationWounds and injuriesRisk factorsjournal articleopen access10.23736/S0022-4707.20.11178-2
