Effet de la pratique des activités physiques et sportives sur la susceptibilité au mal des transports

Abstract : The theory of visuo-vestibular conflict is the most commonly accepted to explain motion sickness (MS). Visual, vestibular and proprioceptive afferences are involved in balance control and this function can be improved by physical and sporting activities (PSA). The purpose of the present survey was to investigate the relations between the susceptibility to MS in adulthood and the practice of PSA, and especially proprioceptive PSA. A questionnaire with items concerning MS susceptibility (MSS) and PSA practice has been completed by 1829 students (22.3+-3.4 years ; 799 males). Subjects having practised a sport before and after the age of 18 are less susceptible to MS in adulthood than subjects without PSA practice (P<0.001). For both sexes combined, the practice of proprioceptive PSA before the age of 18 is more protective from MSS in adulthood than the practice of bioenergetic PSA before this age (RR = 0.45, 95 % CI 0.22-0.92). By practising PSA, subjects are less dependent on visual input and use vestibular afferences better. A process of habituation can be involved in better managing conflicting sensory afferences reducing susceptibility to MS. The practice of proprioceptive PSA develops the proprioceptive afferences and improves their treatment by the central nervous system. This additionnal appropriate input associated with an increase in vestibular weight compared to vision helps overcome visuo-vestibular conflict.
