Abstract

The present study examined the stability of rope jumping skill measured by relative phase under different available sensory information. Nine male and nine female university students were required to perform a sequence of rope jumping at different pacing frequencies (1.4, 1.6, and 1.8 Hz) and in two different conditions: a) rope was turned by the performer itself (haptic information available), and b) rope was turned by others (visual and auditory information available). Passive marks were fixed on the rope and on the hip, knee, and ankle joint for analysis of the dependent variables: height of the rope, height of the jump and discrete relative phase. Overall, the results suggested that the motor pattern for jumping the rope is more stable when the performer herself/himself turns the hope and consequently is able to use haptic information in order to control the motor action as opposed to when only visual and auditory information are available.
