Ten primiparous pregnant women who had normal pregnancies took part in this study in the third and eighth months of the pregnancies. These women were compared with 20 control women who were not pregnant but whose mean age, height and weight were similar to those in the study before their pregnancies started. The maternal heart rate was monitored continuously and the fetal heart rate was recorded telemetrically when the women were carrying 5 kg in each hand with the arms held upright. We will discuss the results that were obtained in the 5 women who followed the course from the beginning to the end of the pregnancy for the sake of this study. The mean heart rate at rest was considerably higher in the pregnant women than in the controls at...

This is why this study has been carried out on ten women between the third and eighth month of pregnancy. The speed at which they walk and the parameters of the gait as well as the localization of the centre of gravity when keeping upright have been measured in these pregnant women as well as in twenty control women of the same age. The results show that the speed at which they walk whether with or without carrying a weight usually is identical at the beginning and the end of pregnancy. When walking normally the size of the steps taken are no larger in pregnant women than in the control patients (p less than 0.05). Though the results are not statistically significant the rhythm of the steps is faster as well as their being a reduction in the length of the steps between the third and eighth month of pregnancy. When carr...

A previous study [1] showed that expertise effect varied whether considering either VFDI or not VFDI. Thus, the selection of two classes for the VFDI seemed to be not wholly appropriate. All the more, variability appeared among experts. Then, this two cluster classes is compared with the classical median. Method: the classic rod and frame test assessed the VFDI for 41 young women participants. A classification was made with a two groups cluster analysis comparatively to a median determination. Usually the population is divided into VFI (error below the median) and VFD (error above the median). Results: With the median, 20 VFD (7.4±2.8 °) and 21 VFI (3±1.1 °) were quantitatively similar with the two classes clusterisation: 21 VFD (7.1±3 °) and 20 VFI (3±1.3°). However this classification was qualitatively different for five subjects. 2 VFD became VFI and 3 VFI became VFD. The threshold was increased of one degree in the clusterisation. Discussion: From the cluster analysis, we propose to solve this qualitative problem with three classes. This should be more heuristic since visual field independent participants could be either dependent to gravito-inertial reference or to proprioceptive information.

First, body sways were analyzed on a free seesaw platform. Fast Fourier transform processing allowed spectral frequency analysis of the platform sways recorded by an accelerometer. Secondly, a visual dependence test, the rod and frame test (RFT) was used. Professional dancers were signi®cantly more stable and less dependent on vision for postural control and for perception than untrained subjects. Presumably, professional dance training strengthens the accuracy of proprioceptive inputs and shifts sensorimotor dominance from vision to proprioception. For the dancers, there was interaction between the RFT visual dependence and the visual control of posture: the less visualdependent they were for the RFT, the more stable they were in dynamic balance conditions. q

The toddlers waited for 0.40 and 0.60m from a slopped ramp axis where a ball dropped and had to perform two series of five hits at five heights. We compared infants who succeeded the task with those who failed it. The two groups showed an invariant relationship for the starting time of the hand movement and the duration of the drop. Regressions were significant between .93 and .99 according to the different conditions. However, the analysis of variability showed differences between the succeeded and failed group. Whatever the conditions, the variability was weakest for the succeeded group. The variability is a good candidate to explain the mastering of the interceptive skill.

Shoulders-hip angles in the horizontal plane and supporting leg (SL) displacements were analyzed with three-dimensional kinematic at the beginning and end of the four turns, identified according to their SL (left vs. right) and turn direction (clockwise, CW vs. counterclockwise, CCW). To begin a turn in CCW on left SL, all the participants turned shoulders before hips (-25 degrees angle), p<0.01. Untrained participants yielded the reverse (+30 degrees angle) in CW - their non-preferred turn - whereas dancers maintained their trunk en bloc. In the turn slow down, in their preferred direction all the participants adopted en bloc behavior to avoid imbalance. Dancers kept this pattern in CCW but untrained participants separated shoulders and hips, p...

Fast Fourier transform processing allowed spectral frequency analysis of the platform sways recorded by an accelerometer. Two frequency bands of the total spectral energy were used: the lower (0 - 2 Hz) and the higher (2 - 20 Hz) frequency bands. Dancers were significantly less dependent on vision but use more proprioception than untrained subjects. Professional dance training appears to shift sensorimotor dominance from vision to proprioception, and this evolution seems more marked for males than females. Female and male dancers had similar dynamic performances, but for males, the better neuromuscular coordination may be associated with biomechanical factors.

Four turn types were defined according to direction (clockwise, CW vs. counterclockwise, CCW) and supporting foot (SF, left vs. right). Visual influences were examined by including two visual conditions (blindfolded vs. full-vision). Motor imagery styles were determined using the Vividness of Movement Imagery Questionnaire (VMIQ) (Kinesthetic, n ¼ 4 vs. Visual/Kinesthetic, n ¼ 6). Turning direction preference was assessed by a closed-response questionnaire in which all dancers indicated that they preferred CW turn direction. Kinesthetic dancers showed more SF displacement during CCW (non-preferred direction) than CW (preferred direction) pirouettes. However, Visual/Kinesthetic dancers showed no significant effect of turn direction. Furthermore, Kinesthetic dancers showed no significant effect of vision on SF displacement whereas Visual/Kinesthetic dancers showed significantly higher SF displacement when vision was occluded. Thus there appears to be a selective effect of vision on Visual/Kinesthetic dancers, and a selective effect of turn direction on Kinesthetic dancers. These results suggest that perceptual styles should be taken into consideration when training tasks that require fine equilibrium control because the factors that perturb balance differ depending on perceptual style.

Visual field dependence was assessed using a rod and frame test on women practising judo or dance (international level) or no specific physical activity. Tests were performed with head upright or tilted head to disturb the Z-axis egocentric reference frame. A cluster analysis determined the distribution of visual field independent (VFI) and visual field dependent (VFD) participants. The first result showed no head position effect for the group of judoists (6 • ± 5 • ; 7 • ± 5 • ) and dancers (4 • ± 2 • ; 5 • ± 3 • ) but a significant effect for untrained participants (5 • ± 2 • ; 7 • ± 3 • ): their visual vertical perception was more disturbed with tilted head than with head upright. A variability exists among experts and would necessitate further analysis. The second result showed no influence of the head position for all VFD participants, whereas for VFI participants significant difference between upright and tilted head appeared both for experts (3 • ± 1 • ; 4 • ± 2 • ) and untrained participants (3 • ± 1 • ; 5 • ± 2 • ). In this research, whatever physical activity level, the VFI participants would mainly use the Z-axis reference frame and rely on proprioceptive information. VFD among experts and VFI among untrained participants suggest that proprioceptive reference frame of neck may not provide alone according the groups an appropriate postural control.

We compared lateral deviations of the centre of pressure when balancing on the left leg and on the right leg in three visual conditions: normal and restricted to each hemifields. Whatever the visual conditions, left-footers displaced the centre of pressure towards the outside of the supporting foot, whereas right-footers displaced it towards the right side for the two feet. Postural control appears to be regulated differently between the two groups of footedness. For left-footers it should be more based upon the perception of the centre of body mass and for right-footers upon the asymmetrical utilization of head receptors.

The support (computerized force platform) was disturbed during roll and pitch sways in association with restriction of the left and right visual hemifields (selective nasal and temporal hemiretina goggles). The effect of training by comparing spontaneous dynamic equilibrium (spectral analysis of body sways) between 14 healthy female right-sided untrained and expert dancers was assessed. The foot of the supporting leg was placed on the unstable platform center in the same way for all the participants. In pitch sways, analysis of variance showed that, regardless of the supporting leg used, dancers oscillated significantly less than untrained participants (p&amp;amp;amp;amp;lt;0.01). Furthermore, all participants were significantly less stable in pitch sways if the left visual field was occluded (p&amp;amp;amp;amp;lt;0.001). However, in roll sways, equilibrium was disturbed by covering the eyes only in dancers (p&amp;amp;amp;amp;lt;0.001). When classical dancers&amp;amp;amp;amp;#39; feet were in an unusual position during the experimental task (a somatosensory constraint for them but not for untrained participants), dancers shifted their spatial reference frame from somesthetic to visual cues. The elimination of this visual reference may have created imbalance, indicating that right hemispheric visual dominance is particularly useful for postural control in complex equilibrium conditions.

Subjects stood (eyes open or eyes closed) on a free seesaw platform, the displacements of which were calculated from accelerometer measures. They were instructed to maintain a vertical position with their frontal plane either parallel (to measure antero-posterior oscillations) or perpendicular to the axis of the platform (to measure lateral oscillations). Girls had a better stability than boys as shown by the smaller displacements of their center of gravity. Untrained subjects, irrespective of sex, were the least stable. Subjects trained in acrobatics were more stable than dancers. Differences related to sex can be attenuated by physical training involving equilibrium exercises which suggests that moderate sustained training could reduce the incidence of falls in aged persons and in professionally exposed workers. dynamic equilibrium I body sway I sport training I sex I classical ballet I acrobats

They included two student groups (beginners and confirmed) and two performer groups (adolescent and adult). They maintained their equilibrium on the platform under different visual and position conditions. The displacements of the seesaw platform were calculated from accelerometer measures. Fast Fourier transform processing of stabilograms allowed spectral frequency analysis. The total spectrum energy and the energies of the three frequency bands (0-0.5 Hz, 0.5-2 Hz, 2-20 Hz) were determined. For all groups, ANOVA indicated that values were higher for eyes-closed than for eyes-open conditions. The visual dependence differed according to age: for 14-year-old students the postural control for dynamic equilibrium was less visually dependent than for 11-year-old students. The 18-year-old dancers, although professional, were more dependent on vision than 14-year-old student dancers. These 18-year-old dancers were still adolescent because they had recently undergone growth acceleration which could disturb their proprioceptive references and internal body representations. Thus, visual input may dominate over the other sensory inputs in the regulation of postural control. © Elsevier, Paris dynamic equilibrium / body sway / vision / male dancer / growth * Correspondence and reprints J.

The statistical analysis showed that the hand movement times were similar regardless of ball rolling heights and that the hand initiation times were dependent on the ball rolling times. Children under 5 years were able to hit a moving ball, and they performed this hitting according to a temporal coupling between ball displacements and the hand contact with it. The participants&amp;amp;amp;amp;amp;amp;#39; behavior of hitting while stepping supports the idea that the motor system implicitly knows what the cognitive system ignores.

They performed kinematic analysis at the start and end of the shoulder-hip horizontal rotations (run-up) with regard to imagery of motor actions. On the basis of the Vividness of Movement Imagery Questionnaire, they classified 8 female expert ballet dancers and 7 untrained female participants according to their movement imagery style (kinesthetic and visual). At the run-up&amp;amp;amp;amp;amp;amp;#39;s end, the shoulders initiated the turn independently of SL but differently depending on training: CW for dancers and CCW for untrained participants (their commonly used direction). Kinesthetic and mixed imagery styles prevailed in dancers, whereas simply a mixed style appeared among untrained participants. Thus, dance training enhances the imagery of kinesthetic sensation and influences the choice of spatial direction, facilitating the body-space interaction.
