Application of supervised and unsupervised classification approaches for the estimation of lactate threshold of endurance runners

[Resumen] Hoy en día el running es, sin lugar a dudas, uno de los deportes más populares que se incorpora como hábito saludable en la vida cotidiana. Dicha práctica deportiva se ve además incentivada por la celebración de múltiples competiciones populares, lo que ha favorecido el cada vez mayor interés por mejorar el rendimiento deportivo así como la seguridad del y la deportista. En este sentido, en la última década se ha extendido enormemente la utilización de Relojes Inteligentes para monitorizar variables fisiológicas. Sin embargo, no todas las variables fisiológicas de interés pueden ser monitorizadas, destacando entre ellas el lactato, cuya medida requiere de muestras de sangre. La curva de lactato permite extraer el umbral de lactato, el cual es fundamental a la hora de planificar entrenamientos y conocer el estado del atleta. Por ello, en este trabajo se propone el diseño y desarrollo de un sensor virtual de lactato. Más concretamente, en este artículo se explora la aplicación de técnicas de agrupamiento de deportistas como vía hacia una estimación personalizada del umbral de lactato.[Abstract] Nowadays, running is one of the most popular sports and it is considered a healthy habit in everyday life. This sport practice is also encouraged by the celebration of multiple popular competitions, which are driving a growing interest in improving athletic performance as well as the safety of the runners. In this sense, in the last decade the use of Smart Watches to monitor physiological variables is becoming more and more common. However, not all the physiological variables of interest can be monitored, among them the lactate, whose measurement requires blood sampling. The lactate curve enables to extract the lactate threshold, which is essential for training-load prescription and assessment. In this work the design and development of a virtual lactate sensor is proposed. More specifically, this article analyzes the applicability of grouping techniques as an alternative towards a personalized estimation of the lactate threshold.Universidad del País Vasco UPV/EHU; GIU18/162Universidad del País Vasco UPV/EHU; PPG17/56Universidad del País Vasco UPV/EHU; PPG/17/40Gobierno Vasco, Departamento de Educación; PRE 2015 1 0129Programa ERASMUS MUNDUS PANTHER; PN/TG1/AUT/PhD/06/201

Building integrated care systems: a case study of Bidasoa Integrated Health Organisation

Introduction: This paper analyses the implementation of integrated care policies in the Basque Country through the deployment of an Integrated Health Organisation in Bidasoa area during the period 2011–2014. Structural, functional and clinical integration policies have been employed with the aim to deliver integrated and person-centred care for patients, especially for those living with chronic conditions.Methods: This organisational case study used multiple data sources and methods in a pragmatic and reflexive manner to build a picture of the organisational development over a 4-year period. In order to measure the progress of integration three concepts have been measured: (i) readiness for chronicity measured with Assessment of Readiness for Chronicity in Healthcare Organisations tool; (ii) collaboration between clinicians from different care levels measured with the D'Amour Questionnaire, and (iii) overall impact of integration through several indicators based on the Triple Aim Framework.Results: The measurement of organisational readiness for chronicity showed improvements in five of the six areas under evaluation. Similarly the collaboration between professionals of different care levels showed a steady improvement in each of the 10 items. Furthermore, the Triple Aim-based indicators showed a better experience of care in terms of patients’ perceptions of care coordination; a reduction in hospital utilisation, particularly for patients with complex chronic conditions; and cost-containment in terms of per capita expenditure.Conclusion: There is a significant amount of data that shows that Bidasoa Integrated Health Organisation has progressed in terms of delivering integrated care for chronic conditions with a positive impact on several Triple Aim outcomes
