Ultrasound analyses of hamstrings musclemorphology changes whit sportR. Santos1, A. Tavares11Instituto Politécnico de Coimbra, ESTeSC – Coimbra Health School,PortugalEmail: rutesantos@estescoimbra.pt; ana.catarina.tavares26@gmail.comIntroductionPhysical activities and sports can change muscle morphology.Changes caused by regular physical exercise can be assessed byultrasound parameters such as the pennation angle, cross-sectional area, echo-intensity and muscle thickness.ObjectivesThis study aims to characterise and evaluate the morphologicalchanges of the hamstring muscles through ultrasound para-meters such as the pennation angle, fascicle length, cross-sectional area, echo-intensity and muscle thickness, and verifythe existence of morphological changes between the dominantand non-dominant limb.MethodologyTwenty-two young female divided in two groups (controlgroup=11; athletes group=11) were submitted to an ultra-sound examination at 50% of the posterior region of the thigh,for the semimembranosus and long portion of the femoralbiceps muscles in the longitudinal and in a panoramic view.Results22 athletes with a mean age of 22.25 years were evaluated.There were significant differences between the two groups inmuscle morphology. The athletes group showed a higher valuefor muscle thickness, cross-sectional area, pennation angle andfascicle length and a lower value for muscle echo-intensity.This group also showed higher values for these parameterswhen dominant limb is compared with non-dominant.ConclusionPhysical exercise causes changes in muscle morphology andultrasound is a good method for the musculoskeletalassessment of athlete’s performance, since it is an imagingmodality that allows to carry out comparative bilateral studiesfor athletes performance follow up and for preventivestrategies against the sedentarism.Correlation between sarcopenia and atherosclerosis/cardiovascular risk factors in the elderly.A Sousa-Coelho1,2,3,4,5, M Botelho1,2, C Guerreiro1, S Pais1,2,5,61CBMR, Centre for Biomedical Research - Universidade do Algarve2CENIE, Centro Internacional sobre o Envelhecimento3ESSUAlg, Escola Superior de Saúde da Universidade do Algarve4CESUAlg, Centro de Estudos e Desenvolvimento em Saúde daUniversidade do Algarve5ABC, Algarve Biomedical Center6DCBM, Departamento de Medicina e Ciências Biomédicas - Universidadedo AlgarveEmail alcoelho@ualg.ptIntroductionSarcopenia is the age-related loss of skeletal muscle mass,strength and function. Uncontrolled diabetes, obesity, chronicinflammation and lipid abnormalities, cause decreases inmuscle strength, which contributes to disease-relatedmorbidity.ObjectivesThe main goal of this study was to correlate the prevalence ofsarcopenia with atherosclerosis and cardiovascular risk factors,mainly estimated by cholesterol, triglycerides, C-reactiveprotein (CRP) and HbA1c levels, in the elderly.MethodologyA quantitative observational cross-sectional study was per-formed in a convenience sample of individuals aged over 60years old recruited non-randomly. Main study variables werebody composition (seca mBCA515), muscle strength (peaktorque, Humac NORM isokinetic dynamometer), risk of falls(TUG test), muscle function (LEFS) and lipids, inflammationand glycaemic profile (cobas b101-Roche).ResultsTotal cholesterol levels fully correlated with LDL and non-HDL cholesterol, and partially with triglycerides, but not withHDL-cholesterol levels, HbA1c, or BMI. LDL-cholesterol levelsdid not correlate with muscle mass (free-fat mass (%)),strength, function, or risk of falls. Similarly, HDL-cholesterollevels did not correlate with muscle function or falls risk.Cholesterol ratio, obtained by dividing total cholesterol byHDL-cholesterol levels, was significantly higher in individualswith CRP levels above 3 mg/L. Interestingly, when compared tonormal values, individuals with triglycerides above 150 mg/dLshowed a statistically significant decrease in muscle strength.ConclusionFrom the biochemical measured parameters, our data showedthat only high triglycerides levels positively correlated withsarcopenia risk, demonstrated by reduced muscle strength.While cholesterol ratio positively correlated with increasedinflammation, blood cholesterol levels seem to be independentfactors regarding sarcopenia prevalence.Influence of Food Education on the quality of snacksof middle school childrenD Andrade11Municı́pio de SoureEmail: dsandrade.nutri@gmail.comIntroductionThe window of opportunity for the creation of eatingbehaviours and preferences, occurs during the early years,and will be reflected throughout the rest of their lives. Theschool represents an ideal environment to apply behaviouralshaping strategies and to create eating habits, but can also benegatively affected by unbalanced eating behaviours. Cognitiveperformance is influenced by their diet, and a deficit ofimportant nutrients harms school productivity, enhancing theimportance of creating habits of making healthy, balanced andcomplete snacks.ObjectivesTo evaluate the quality of middle school children snacks, andto comprehend the influence of Food Education on theimprovement of this same qualityMethodologyMake a detailed initial registration of the snacks composition(morning and afternoon snacks), for 5 consecutive days. Then,apply lectures of Food Education throughout the school year,enhancing what is the ideal composition of these snacks.Repeat the registration of the school snacks, at the end of theyear, in order to compare the data gathered before and afterthe Food Education qualification.ResultsThrough comparing the initial and final registration, it’spossible to see differences in the quantity of some food groups:grain bread (4% to 7%), even though refined bread alsoincreased (51% to 53%); plain milk (29% to 37%), indetriment to flavoured milk (10% to 4%); sugared cakes andcookies, with or without filling (23% to 6%); industrial pastryshop products (27% to 7%).ConclusionBased on the results gathered, it is possible to conclude that acontinuous Food Education, focused on improving schoolsnacks, led to a significant improvement of the nutritionalquality of food choices, enhancing the importance and need ofinstruct children during their early school years, involving theenvironment of their everyday lives.Inflammation disrupts epithelial barrier function andinduces the release of different populations ofexosomesB Martins1,2, T Rodrigues1,2, J Ramalho3, A Ambrósio1,2, H Girão1,2,R Fernandes1,21Coimbra Institute for Clinical and Biomedical Research (iCBR), Faculty ofMedicine, University of Coimbra (FMUC), Portugal2Center for Innovative Biomedicine and Biotechnology (CIBB), University ofCoimbra, Portugal3Centro de Estudos de Doenças Crónicas (CEDOC) and NOVA MedicalSchool, Faculdade de Ciências Médicas (NMS/FCM), PortugalEmail: mrro.54@gmail.comii22 European Journal of Public Health, Vol. 30, Supplement 2, 2020Downloaded from https://academic.oup.com/eurpub/article/30/Supplement_2/ckaa040.064/5862119 by Universidade do Algarve user on 21 March 2023
