Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The research team leading this project frames it within the objective of advancing knowledge about what happens to this group of athletes who participate in Ultratrail events, with the particularity of studying them during the race itself. To achieve this, the study aims to address four key perspectives.

First, it seeks to understand the training habits of male and female Ultratrail runners. Second, it aims to assess their physical condition and analyze how uphill and downhill segments affect their muscle performance, running efficiency, and strength levels. Third, it investigates the key factors that determine the prediction of race performance for both male and female runners. Finally, the fourth objective is to examine sex differences as a conditioning factor in physiological processes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

There is a category of sporting events held in natural environments over very long distances, classified as Ultratrail races. These races have grown in popularity, attracting an increasing number of participants.

Such races induce states of exhaustion and fatigue, with performance being influenced by numerous factors (environmental conditions, terrain, course profile, etc.), in addition to the athlete's individual characteristics. Scientific interest in these events has surged, and the research community is closely monitoring the health status of participants and their involvement in such races. The aim is to identify the factors influencing performance in a 106 km race (Castelló-Penyagolosa of Penyagolosa Trails) and to assess the physiological impact of participating in this type of endurance event.

To conduct this study, data collection took place before the race, during the race, and within the 48-hour post-race recovery phase.

Before the race, two laboratory sessions were conducted to analyze the athlete's physical condition and assess muscle damage under conditions of both uphill and downhill running. Blood samples were taken before and after these tests.

On race day, measurements included strength loss, weight, dehydration levels, race nutrition, and the evolution of physiological parameters through blood and urine analyses conducted before and after the race.

Finally, blood samples were collected at 24-hours and 48-hours post-race to track the progression of physiological parameters during the recovery phase.
