Does gaming keep subjects awake?: Subjective and objective sleep parameters following gaming in comparison to a passive control.

Objectives: Gaming is a global phenomenon often associated with impaired health and sleep patterns. Although the research activities are growing, the evidence to date is rare due to the various gaming titles and inconsistent study designs. Thus, this study aimed to examine the impact of excessive gaming in the evening on subjective as well as objective sleep parameters by focusing on specific game titles and assessing several evenings/nights using a mixed-methods approach.

The prevalence and impact of sarcopenia in older cardiac patients undergoing inpatient cardiac rehabilitation - results from a prospective, observational cohort pre-study.

Background: The prevalence of sarcopenia and its impact in older patients undergoing inpatient cardiac rehabilitation (iCR) after cardiac procedure has been insufficiently studied. The main aim of this study was to evaluate the prevalence of sarcopenia and quantify the functional capacity of older sarcopenic and non-sarcopenic patients participating in iCR.

Methods: Prospective, observational cohort study within the framework of the ongoing multicenter prehabilitation study "PRECOVERY".

Development of a Core Set of Quality Criteria for Virtual Reality Applications Designed for Older Adults: Multistep Qualitative Study.

Background: Virtual reality (VR) applications are gaining growing significance, particularly among older adults. These applications can provide valuable support to older adults by offering immersive VR content that positively influences various aspects of their daily lives, including activities of daily living. Furthermore, VR applications can contribute to the enhancement of cognitive and motor skills, ultimately leading to an improved quality of life for older individuals.

The ESA Parastronaut Feasibility Project: Investigating the Need and Contents of Physical Performance Tests for an Inclusive European Astronaut Corps.

Introduction: In 2022, the European Space Agency (ESA) held the first astronaut selection since the beginning of space flight that allowed physically impaired astronaut candidates to be selected in an inclusive European astronaut corp. The main objective of the 'parastronaut feasibility project' is to investigate if physical performance tests (PPTs) should be part of future astronaut recruitments for an inclusive ESA astronaut corps to test their flight readiness. The objectives of this study are (1) to assess if future (para-)astronaut recruitment campaigns should include PPTs to ensure flight readiness, safety, and mission success; (2) if so, which areas of physical performance should be tested to mimic nominal and off-nominal crew activities during all phases of a space mission; and (3) to assess whether PPTs are compatible with the ethical principles of equal opportunity for an inclusive pool of astronaut candidates.

#fitspiration: a comparison of the sport-related social media usage and its impact on body image in young adults.

Background: Following and posting sport-related content on social media is wide-spread among young people. To date, little is known about the interdependence between sport-related social media use and the thereby perceived personal body image.

Methods: We conducted an online survey (N = 285) to examine how social media influences the sport-related body image.
