Study of the Kinetics of the Determinants of Performance During a Mountain Ultramarathon: Multidisciplinary Protocol of the First Trail Scientifique de Clécy 2021.

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.

How physical activity and passion color the passage of time: A response with ultra-trail runners.

The aim of this study was to replicate the results of a lengthening effect caused by physical activity already observed in duration length judgment, using the time passage judgment measure, while exploring the effects of passion types (obsessive vs. harmonious) on time perception. A total of 378 ultra-trail runners responded to an online questionnaire in which the type of passion and the passage of time (PoT) judgments associated with both an ultra-trail context and a non-trail daily context were collected. The results showed that participants systematically judged the time as being dilated in a situation of sports practice, thus extending the results obtained in interval duration judgment studies. This study also showed an influence of the type of passion: higher levels of harmonious passion were related to greater feelings of time dilation, while higher levels of obsessive passion were related to greater feelings of both time contraction and time dilation. Results are discussed in light of the two major factors that influence the PoT referenced in the literature, namely, attention and happiness level.

Successful aging: analysis of the components of a gerontological paradigm.

Since the mid-20th century, scientist has been searching the components of successful or active aging. At the beginning of the 21st century, demographic aging is now a global issue and successful aging has emerged as a gerontological paradigm through nation and international policies. Conducting a comprehensive review of scientific literature on this paradigm offers the opportunity to identify the key components of successful aging. Based on the results of this approach, we show that the components are not limited to the functional and cognitive health of individuals. Multidimensionality of successful aging highlights the complexity of factors influencing the experiences of aging, and the variety of dimensions involved: functional, psychological, social, spiritual or environmental. Representations and aspirations of what would be successful aging differ from one society to another, from culture to another. The article proposes a framework for an exploratory analysis of the vulnerabilities of elderly not to assess the success of aging, but to capture the components of the well-being of people in old age.

[The DATEL (diagnosis for territorial action environment and longevity), a territorial diagnosis for a future with our elders]. / Le diagnostic action territorial environnement longévité (Datel) : un diagnostic territorial pour construire un avenir commun avec les aînés.

The territorial structure is such that it is necessary to go through a step of diagnosis. Ageing must be apprehended in all its aspects, but the multiplicity of actors involved prevents the local powers from getting a comprehensive vision of the stakes and from implementing the adequate policies. The gerontopôle of "Pays de Loire" has developed an original method of diagnosis consisting in a comprehensive approach so called DATEL (diagnosis for territorial action environment and longevity). It is based on three aspects: an analysis of the geographical areas, a diagnosis shared by citizens and local councilors according to the Vancouver method, and a prospective review of the medico-social and health situation which integrates all services and forces at work and their potential demographic evolution. This DATEL aims to give local politicians the means to take well-informed decisions that will sustain the rapid demographic evolution of the ageing population and will maintain a good quality of life for our elders.
