Background: Reliability refers to the precision of an assessment, so it is a critical topic to take the right decisions related to health management. People usually perform several tasks at the same time in their daily life. The aim of this study was to examine the reliability of the 30-s chair stand test in people with type 2 Diabetes Mellitus (T2DM) with test–retest, with and without dual-task (motor + cognitive task). Methods: Twenty-six subjects with T2DM and 30 subjects without T2DM performed the 30-s Chair Stand Test (30sCST) in which they must sit and stand as many times as possible in 30 s. They performed the test in the usual way (30sCST) and also with an additional cognitive task (30sCST-DT). A retest was conducted 7–14 days later. Results: Relative reliability was excellent in both groups (intraclass correlation coefficient > 0.9). In 30sCST-DT, relative reliability was high in the T2DM group (intraclass correlation coefficient > 0.7) and excellent in subjects without T2DM (intraclass correlation coefficient > 0.9). Conclusions: The 30sCST and the 30sCST-DT tests are reliable tools for people with T2DM to measure changes after an intervention. The smallest real difference was 15% and 20% upper in the T2DM group in the 30sCST and 30sCST-DT tests, respectively.

The practice of sports activities related to nature and the environment is a social and tourist phenomenon that is increasingly popular. In this paper, we aim to find and analyze the sociodemographic characteristics of tourists who take trips in order to find and enjoy trekking opportunities. Thus, it seeks to facilitate the design of offers of more sustainable activities aimed at this public which contribute to the development of an efficient tourism model to preserve the environment. The research has been carried out by analyzing the data obtained from the travel file of the Resident Tourism Survey of the National Statistical Institute for 2019. The profile of the trekking tourist in Spain is Spanish, married, lives as a couple, and very well educated. Participants are usually busy and use their car, other private vehicles, or destination-provided transportation. They tend to stay in the homes of family, friends, or their employer on their trips. This information is relevant for the design of sustainable tourism products since by knowing the priorities of this profile of tourists, more sustainable activities can be elaborated and better development and protection of the environment can be achieved.
