Background The growing interest of the scientific community in trail running has highlighted the acute effects of practice at the time of these races on isolated aspects of physiological and structural systems; biological, physiological, cognitive, and muscular functions; and the psychological state of athletes. However, no integrative study has been conducted under these conditions with so many participants and monitoring of pre-, per-, and postrace variables for up to 10 days over a distance close to 100 miles. Objective The aim of this study was to evaluate the kinetics of the performance parameters during a 156 km trail run and 6000 m of elevation gain in pre-, per-, and postrace conditions. The general hypothesis is based on significant alterations in the psychological, physiological, mechanical, biological, and cognitive parameters. Methods The Trail Scientifique de Clécy took place on November 11, 2021. This prospective experimental study provides a comprehensive exploration of the constraints and adaptations of psychophysiological and sociological variables assessed in real race conditions during a trail running of 156 km on hilly ground and 6000 m of elevation gain (D+). The study protocol allowed for repeatability of study measurements under the same experimental conditions during the race, with the race being divided into 6 identical loops of 26 km and 1000 m D+. Measurements were conducted the day before and the morning of the race, at the end of each lap, after a pit stop, and up to 10 days after the race. A total of 55 participants were included, 43 (78%) men and 12 (22%) women, who were experienced in ultra–trail-running events and with no contraindications to the practice of this sport. Results The launch of the study was authorized on October 26, 2021, under the trial number 21-0166 after a favorable opinion from the Comité de Protection des Personnes Ouest III (21.09.61/SIRIPH 2G 21.01586.000009). Of the 55 runners enrolled, 41 (75%) completed the race and 14 (25%) dropped out for various reasons, including gastric problems, hypothermia, fatigue, and musculoskeletal injuries. All the measurements for each team were completed in full. The race times (ie, excluding the measurements) ranged from 17.8206 hours for the first runner to 35.9225 hours for the last runner. The average time to complete all measurements for each lap was 64 (SD 3) minutes. Conclusions The Trail Scientifique de Clécy, by its protocol, allowed for a multidisciplinary approach to the discipline. This approach will allow for the explanation of the studied parameters in relation to each other and observation of the systems of dependence and independence. The initial results are expected in June 2022. International Registered Report Identifier (IRRID) RR1-10.2196/38027
Cet article s’intéresse au renouvellement des pratiques en matière de planification et d’aménagement du territoire dans la région métropolitaine interprovinciale d’Ottawa-Gatineau, où le développement urbain durable et la concertation à l’échelle métropolitaine sont récemment devenus des objectifs officiels de l’action publique. Les auteurs formulent l’hypothèse selon laquelle le manque de concertation des intervenants responsables de l’aménagement du territoire d’Ottawa-Gatineau est principalement attribuable à la complexité de la gouvernance métropolitaine ainsi qu’à leurs importantes divergences d’intérêts politiques, économiques et sociaux, ce qui constitue le principal obstacle à la coordination des transports et de l’urbanisme dans une perspective de développement durable à l’échelle métropolitaine. Ils démontrent que la concertation municipale y est en cours de généralisation, mais qu’elle présente encore des défaillances procédurales majeures et que la concertation interprovinciale y est amorcée depuis longtemps, mais ne figure toujours pas au sommet des priorités des organisations publiques.This paper focuses on the renewal of land use planning practices in the interprovincial metropolitan area of Ottawa-Gatineau, where sustainable urban development and metropolitan cooperation recently became official targets of public action. The authors formulate the hypothesis that the lack of cooperation between stakeholders responsible for land use planning in the region is due primarily to the complexity of interprovincial governance and to significant divergences in the political, economic and social interests of those stakeholders. Taken together, these factors constitute the main impediment to sustainable, integrated transportation and land use planning at the metropolitan level. The authors find that municipal collaboration is in fact increasing, but is marred by serious procedural flaws and that the interprovincial cooperation process, though initiated long ago, is still not a top priority for public organizations.Este artículo trata del cambio de prácticas en materia de planificación y de ordenación territorial, en la región metropolitana interprovincial de Ottawa-Gatineau, donde el desarrollo urbano sustentable y la concertación a escala metropolitana constituyen objetivos oficiales recientes de la acción pública. Los autores formulan como hipótesis la falta de concertación de las personas responsables que intervienen en el ordenación territorial de Ottawa-Gatineau, atribuible principalmente a la complejidad de la gobernación metropolitana y a las divergencias importantes de intereses políticos, económicos y sociales, lo que constituye el obstáculo principal a la coordinación de transportes y del urbanismo, en una perspectiva de desarrollo sostenible a escala metropolitana. Los autores demuestran que la concertación municipal se generaliza, aunque todavía presenta aún dificultades procesales mayores, y que la concertación interprovincial iniciada antaño aún no figura entre las prioridades de las organizacio...
