: We hypothesized that exercise performance is adjusted during repeated sprints in order to not surpass a critical threshold of peripheral fatigue. Twelve men randomly performed three experimental sessions on different days: one single 10 s all-out sprint and two trials of 10 × 10 s all-out sprint with 30 s of passive recovery in between. One...

Dans ce rapport, on propose un modèle de génération d'un processus stochastique à partir du mouvement des deux jambes lors d'un exercice de pédalage. On montre qu'il est stationnaire et que le rapport d'amplitude du fondamental par rapport à la première harmonique est, entre autre, fonction d'un retard systématique entre les deux jambes.

Cette recherche a été menée dans le contexte scientifique proposé par l'équipe BIOMED (Pr. H. RIX), équipe qui regroupe des chercheurs du laboratoire I3S et des médecins (F. RAYBAUD, G. SUISSE) , Praticiens Hospitaliers, ayant une formation scientifique complémentaire (DEA ou Doctorat SPI). Cette association permet d'aborder des problèmes réels...

The estimation of the cilia beating frequency (CBF) is of great interest in understanding how the CBF modulates liquid fluxes and how it is controlled by the ciliated cell intra- and/or extra-cellular medium composition in physiological processes. Motion artifacts and camera defaults may hinder the computation of the frequency variations during...

It has been shown that a pedaling frequency component can be extracted from the heart rate variability (HRV) signal using a time-varying filter. It is shown that this filter can be implemented directly in the time-frequency plane with different approaches. The need of resampling the data is also discussed with regard to the artifacts produced...

During exercise, analysis of the spectral components of the heart rate variability (i.e. R-R interval series variability; HRV) points out a new high frequency component related to the pedalling frequency. This component is independent of the classical low and high frequency bands related to the autonomic nervous system modulation of the heart...

T waves properties are not usually fully exploited when analyzing its profile variation within a set of records. An affine transform of the temporal support is a good candidate for the modeling of this variation. Based on this assumption, we propose here a new framework that provides an estimation of the reference T wave and the parameters of...

Atrial fibrillation dominant frequency (AFDF) has been demonstrated to provide useful information on the characteristics of atrial fibrillation. The present work points forward a new method for AFDF estimation directly from a single-lead ECG recording, exploiting the concept of compressed spectrum as spectral estimator. The main purpose is to...

Motile cilia play a major role in fluid circulation in many biological systems such as the oviduct, the airway and the cerebral ventricles and defects in cilia beating lead to pathologies called ciliopathies. The estimation of the cilia beating frequency (CBF) is of great interest to understand how the CBF modulates the liquid fluxes and how...
