COMPARISON OF TWO PEDALING SENSORS, ICRANKSET AND SRM, AGAINST A STANDARD REFERENCE SENSOR

Our aim was i) to validate the I-Crankset sensor (I-CS) with a reference torque sensor (RTSL) for the calculation of crankset torque, power and work outputs and ii) to compare I-CS with the SRM sensor, a popular device. SRM and I-CS sensors were mounted simultaneously on a test bench instrumented with the RTSL used to validate I-CS. The protocol included multiple sets of 30 pedaling cycles in three conditions to explore various solicitations. Torque magnitudes, angular velocity and power output were compared using the coefficient of multiple correlation inter-protocol. The results showed a good validity of both the I-CS and SRM for all the conditions in comparison to RTSL for torque’s measurements and power’s calculations, even if an average angular velocity is used by SRM. But this one showed its limitations when calculating the work output

SLIDING ON HARDCOURT SURFACE WITH SPECIFIC SHOES, PRELIMINARY RESULTS

The purpose of this study was to investigate the sliding characteristics of a new shoe (NSh) concept. The NSh has been developed with the specific aim of facilitating sliding on hard surface such as tennis players can do on clay or synthetic turf. Five young tennis players performed several trials on a walkway instrumented with seven force platforms synchronized with a motion capture system. Results revealed that the coefficient of friction was still higher for the NSh-hard surface condition than for the regular shoesynthetic turf condition but the players were able to obtain the same sliding length provided that approach velocity was higher

Recognition of Emotions From Facial Point-Light Displays

International audienceFacial emotion recognition occupies a prominent place in emotion psychology. How perceivers recognize messages conveyed by faces can be studied in either an explicit or an implicit way, and using different kinds of facial stimuli. In the present study, we explored for the first time how facial point-light displays (PLDs) (i.e., biological motion with minimal perceptual properties) can elicit both explicit and implicit mechanisms of facial emotion recognition. Participants completed tasks of explicit or implicit facial emotion recognition from PLDs. Results showed that point-light stimuli are sufficient to allow facial emotion recognition, be it explicit and implicit. We argue that this finding could encourage the use of PLDs in research on the perception of emotional cues from faces
