Estrés percibido y felicidad auténtica a través del nivel de actividad física en jóvenes universitarios
2020
Se ha demostrado en la literatura que el estrés y la felicidad se han relacionado de diversas maneras, y estas a su vez, también se relacionan con la práctica de actividad física (AF). El objetivo de este trabajo fue poner a prueba el papel de la AF en la reducción del estrés y el aumento de la felicidad, así como su rol mediador en la relación entre ambas variables. Concretamente, se pusieron a prueba las siguientes hipótesis: 1) la percepción del estrés (con o sin control de la situación estresante) y la felicidad auténtica difieren en función del nivel de AF; 2) a mayor práctica de AF, mayor percepción de control en la situación estresante y menor percepción de sentirse sobrepasado por l…
Physical fitness and anthropometrics in Finnish soldiers during their early career: prospective changes during a 3-year follow-up.
2020
IntroductionPhysical fitness is a fundamental capability required of military personnel, but studies focusing on longitudinal changes in physical fitness and anthropometrics in soldiers are lacking. The aim was to evaluate physical fitness and anthropometrics in soldiers during their early career.MethodsA 3-year prospective study included 180 male soldiers (baseline age 26±2 years) with measures of a 12 min running test, standing long jump, sit-up and push-up tests, and body mass, height and waist circumference (WC). Baseline data were stratified into tertiles, and the changes within each tertile were analysed using dependent t-tests and analysis of variance.Results12 min running test dista…
Impact of using different levels of threshold-based artefact correction on the quantification of heart rate variability in three independent human co…
2020
Heart rate variability (HRV) is a non-invasive indicator of autonomic nervous system function. HRV recordings show artefacts due to technical and/or biological issues. The Kubios software is one of the most used software to process HRV recordings, offering different levels of threshold-based artefact correction (i.e., Kubios filters). The aim of the study was to analyze the impact of different Kubios filters on the quantification of HRV derived parameters from short-term recordings in three independent human cohorts. A total of 312 participants were included: 107 children with overweight/obesity (10.0 ±
