For each test, electromyographic signal (EMG) of quadriceps muscle was characterised in the spectral domain by calculating total energy (ET) and mean power frequency (FM). During incremental test, cardio-respiratory variables (heart rate, O<sub>2</sub> consumption, CO<sub>2</sub> production) and metabolivariables (glycemia, lactatemie, and kaliemia) were measured. According to a healthy children group (SNS), DID showed in isometric condition a fatigability more important. In dynamic condition, changes m cardio-respiratoiry variables were similar while metabolic variables were differently modified. Changes in ET mid FM were illustrated by specific profiles for children with respect to adolescent children (quasilinear increase for ET, relative stability for FM). Using a discriminant analysis, SNS and DID children may be differencied. Thus, EMG signal reflects metabolic changes during incremental test and may be used to characterized DID physical aptitude.</p></div>","PeriodicalId":101059,"journal":{"name":"RBM-News","volume":"21 9","pages":"Pages 193-199"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0222-0776(00)87252-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76980282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The EHG being corrupted by different electromagnetic noises, we have developed specific algorithms, based on wavelet decomposition, for the denoising of the EHG. Classical parameters, extracted from the spectral and temporal representations and from the instantaneous frequency of the EHG, have permitted us to follow the solution of the signals during pregnancy, Furthermore, a discriminant analysis permitted us to evidence a difference between contractions leading to term or preterm deliveries, as soon as 30 WG Non-stationary parameters have then been computed from EHG signals, in order to follow the two electrical waves that are known on animal recordings to be related to contraction efficiency. The extraction and characterization of these waves are made by extracting the ridges of the scalogram, computed from the continuous wavelet transform. The instrumental part development has started with the analysis of maternal movement artifacts, and with the comparison of different kinds of electrodes, suitable for 24 hours recording. A first portable recorder prototype is presently under development.</p></div>","PeriodicalId":101059,"journal":{"name":"RBM-News","volume":"21 9","pages":"Pages 200-211"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0222-0776(00)87253-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85856487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
