There is extensive knowledge about uphill running on a treadmill, although paucity regarding the influence of uphill trail running on exercise capacity in runners. The purpose of this study was to compare an uphill field test with a treadmill test with 1% inclination especially considering cardiopulmonary exercise variables. The difference in those tests between a group of trail runners and a group of road runners was tested for establishing a test specifically for trail runners. Ten male endurance road runners and ten male trail runners performed one maximal incremental treadmill test with 1% inclination and a maximal incremental field test on a hill at 16% inclination which they were instructed to run up four times for three minutes, each time with a higher pace. A mobile cardiopulmonary exercise testing unit was used to measure ventilation. There were no significant differences between trail runners and road runners. The equivalence factor was comparable between both groups. was comparable for both test protocols. However, there was a significant difference between the two test protocols regarding lactate concentration, the respiratory exchange ratio, running cost, heart rate, Breathing reserve, and O. The greater lactate concentration and running cost recorded uphill indicate a higher energy demand during trail running than level road running.

: Unlike road running, mountain and trail running typically cover longer distances and include uphill and downhill segments that impose unique physiological and mechanical demands on athletes. : This study aimed to identify morphological differences in the patellar and Achilles tendons between trail and road runners. Moreover, the potential influence of weekly mileage and accumulated positive elevation gain on the morphology of both tendons was obtained.

Introduction And Objective: Research on runners is most often conducted in the context of sports motivation using the adaptation of the Motivations of Marathoners Scale (MOMS) questionnaire, which, however, does not measure aspects related to tourism, nature or socio-cultural aspects. The aim of the study was to create a Polish adaptation of the Sports Tourism Motivation Scale (STMS) for athletes, especially runners, which, for the first time, enables the examination of socio-cultural and tourism-related aspects among them in Poland.
Material And Methods: To conduct the adaptation, the STMS tool was tested among 100 individuals who engage in running: 50 participating in a city-organized running event around cultural monuments (2022 Poznań Marathon) and another 50 individuals running on non-urban routes - in a national park (2022 Łemkowyna Ultra-Trail), exemplified by a nature-surrounded running activity.

This study aimed to assess the calcaneal bone mineral density (BMD) of elite female trail runners and evaluate its reliability using a novel DXA method. It also examined the relationship between calcaneal BMD and other regions of interest to better understand bone health in this specific population. A cross-sectional study was conducted with 35 elite female trail runners from the Spanish national team.

Objective: To explore the correlation between park view elements and their combinations on the heart rate (HR) and speed of walkers, joggers, and runners in different groups of people's profiles and walking types, provide suggestions for the planning and design of walking suitability of walking trails in parks, and guide people with different walking needs to scientifically choose walking trails in parks.
Methods: Profile data and exercise data of users who recorded walking activities in Century Park are collected on Strava, and the park view images (PVIs) were taken and segmented semantically. Data are grouped according to gender, age, weight and exercise type, and the quantitative relationship between HR, speed and 17 park view elements is studied by Spearman correlation analysis.

Article Synopsis
- * Fifteen trained trail runners (10 males and 5 females) participated in a VK race, utilizing advanced equipment to measure their physiological responses, revealing significant differences in multiple respiratory and cardiovascular variables between genders and performance levels.
- * Key performance indicators such as oxygen consumption and carbon dioxide production were identified, highlighting the importance of muscular adaptations and respiratory capacity for success in these intense, short-duration races.
