Mentalizing eye contact with a face on a video : Gaze direction does not influence autonomic arousal
2018
Recent research has revealed enhanced autonomic and subjective responses to eye contact only when perceiving another live person. However, these enhanced responses to eye contact are abolished if the viewer believes that the other person is not able to look back at the viewer. We purported to investigate whether this “genuine” eye contact effect can be reproduced with pre‐recorded videos of stimulus persons. Autonomic responses, gaze behavior, and subjective self‐assessments were measured while participants viewed pre‐recorded video persons with direct or averted gaze, imagined that the video person was real, and mentalized that the person could see them or not. Pre‐recorded videos did not …
A MICRO-ARCHITECTURAL BASED STRUCTURAL MODEL FOR ELASTOMERIC ELECTROSPUN SCAFFOLDS FOR HEART VALVE TISSUE ENGINEERING
2010
BACKGROUND. Improving how scaffold architectures affect cell morphology, metabolism, phenotypic expression, and predicting mechanical behaviors, are crucial goals in the development of engineered heart valve scaffolds. Studies are required to elucidate how the fibrous microstructure translates into specific tissue (or meso-scale) level mechanical behavior. Deterministic structural models can quantify how key structures contribute to the mechanical response as a function of bulk deformation across multiple scales, as well as provide a better understanding of cellular mechanical response to local micro-structural deformations. An appropriate representative volume element (RVE) size was determ…
Heart of Spain
1991
Heart of Spain no es sólo el título de un film sobre la guerra civil española; es también una constante apelación y una retórica. Una metáfora biológica que se muda en sentimental y a la que se refiere repetidamente el cine de la posguerra. Coloquemos junto a esta metáfora otra que le suele acompañar, también física: la herida. Es así como toma cuerpo el universo al que remiten los films de la posguerra: por una parte, apelando a la grandeza ampulosa del corazón español, corazón éste siempre del lado de los vencedores (el valor, el amor a la patria, a la familia, a la tradición), mientras frente a él se advierte la aplicación deshumanizada de las consignas republicanas, tachadas con papanat…
Resting electrocardiogram and blood pressure in young athletes and nonathletes : A 4-year follow-up
2022
A follow-up data on electrocardiogram (ECG) and blood pressure (BP) changes in adolescent athletes are scarce. We compared ECG and BP between adolescent athletes and non-athletes in a 4-year follow-up. A total of 154 youth sports clubs (SC) in Finland and 100 secondary schools for comparison data participated in this observational follow-up study. Those who maintained or adopted SC participation are referred to as “Always athletes” (n=137), those who never participated in SC as “Never athletes” (n=108) and those who dropped out of SC during the follow-up as “Changers” (n=116). The mean age of the participants was 15.5 (0.6) years in all study groups at baseline. Resting ECG including heart …

The Effects of Combined Same Session Aerobic and Resistance Training on Physical Performance in Coronary Artery Disease Patients : Protocol Comparison
2021
Aerobic training is included to cardiac rehabilitation programs together with resistance training. The effects of combined aerobic and resistance training performed in a same session with different protocols on peak aerobic capacity (VO2peak) and maximal dynamic strength (1RM: one repetition maximum) are not well known. We compared the effectiveness of two different combined aerobic and resistance training programs for 12 weeks performed three times in a week in stable Coronary Artery Disease (CAD) patients (n=30) who had previously performed aerobic training only. The patients were randomized to High Volume- Low Intensity Group (HLG) or Low Volume-High Intensity Group (LHG). Both groups pe…
Changes in nocturnal heart rate variability and endurance performance during a high-intensity or high-volume endurance training period in recreationa…
2014
It is known that endurance training affects the modulation of the autonomic nervous system and heart rate variability (HRV). As a method HRV may be a potential tool to monitor trainability and endurance training adaptation. The purpose of this study was to examine changes in nocturnal HRV indices and endurance running performance during high intensity versus high volume endurance training. In total, 28 recreational male and female endurance runners (35 ± 8 year, VO2max 50 ± 5 ml/kg/min) were matched into two training groups after the 8 week basic training period (BTP) according to HRV, endurance performance and training adaptation during BTP. During the 8 week hard training period (HTP), th…
Individualized Endurance Training Based on Recovery and Training Status in Recreational Runners
2022
Purpose Long-term development of endurance performance requires a proper balance between strain and recovery. While responses and adaptations to training are highly individual, this study examined whether individually-adjusted endurance training based on recovery and training status would lead to greater adaptations compared to a predefined program. Methods Recreational runners were divided into predefined (PD, n = 14) or individualized (IND, n = 16) training groups. In IND, the training load was decreased, maintained or increased twice a week based on nocturnal heart rate variability, perceived recovery, and heart rate-running speed index. Both groups performed three-week preparatory, six-…
