The aim of this study was to evaluate the stress suffered by medical residents as the result of being on call for 24 hours, from a multidimensional approach. Two groups of medical residents selected according to their work shift, participated in the study: one group ( n = 40) was sleep-deprived after having been actively on-call for 24 hours, and another contrast group ( n = 18) had performed a normal work day and were not sleep-deprived. All participants completed pre-post measures during a 24 h cycle. These were administered on both occasions at 8 am. The measures included HRV, cortisol, cognitive performance and transitory mood. The effect of the group x phase interaction was significant for all variables analysed, indicating that doctors in the 24h on-call shift group showed significant deterioration in all physiological, performance and mood indicators in comparison with the participants in the group not on call. These results suggest the need to review medical on-call systems, in order to reduce the stress load, which has a direct effect on working conditions.

Context: The emergence of COVID-19 caused a new public health crisis, leading to major changes in daily life routines, often including physical activity (PA) levels. The main goal of this study was to analyze the differences in self-reported physical activity of people with complete spinal cord injuries between the time prior to the COVID-19 lockdown and the lockdown period itself. Methods: A sample of 20 participants with complete thoracic spinal cord injuries completed the Physical Activity Scale for Individuals with Physical Disabilities before and during the COVID-19 lockdown. Results: The results showed differences between the pre-lockdown and lockdown measurements in total selfreported PA (z= −3.92; P<0.001; d=1.28), recreational PA (z=−3.92; P<0.001; d=1.18) and occupational PA (z= −2.03; P=0.042; d=0.55). Nevertheless, no differences were found in housework PA between the two time periods. Furthermore, the results showed differences in total minutes (z= −3.92; P<0.001; d=1.75), minutes spent on recreational activities (z= −3.82; P<0.001; d=1.56) and minutes spent on occupational activities (z= −2.032; P=0.042; d=0.55) of moderate/vigorous intensity. Conclusions: Individuals with thoracic spinal cord injuries who were full-time manual wheelchair users displayed lower levels of PA during the pandemic than in the pre-pandemic period. The results suggest that the prohibition and restrictions on carrying out recreational and/or occupational activities are the main reasons for this inactivity. Physical activity promotion strategies should be implemented within this population to lessen the effects of this physical inactivity stemming from the COVID-19 pandemic.

En la actualidad, la crisis sanitaria derivada de la aparición del COVID-19 ha repercutido de forma significativa en las vidas de la población, la cual ha experimentado muchos cambios en un espacio muy corto de tiempo. Los estudiantes universitarios son una de las poblaciones que más se han tenido que adaptar a este contexto pandémico, lo cual puede haber generado nuevas situaciones de estrés, afectando a su salud mental. El objetivo principal de este estudio es analizar los niveles de estrés académico de una muestra de estudiantes universitarios, así como identificar los principales estresores, sintomatología asociada al estrés y las estrategias de afrontamiento adoptadas por cada género. La muestra estuvo compuesta por 351 estudiantes universitarios (211 mujeres) a los que se les facilitó el Inventario Sistémico Cognoscitivista (SISCO) para el estudio del Estrés Académico adaptado al contexto de la crisis por COVID-19. Los resultados hallados mostraron diferencias significativas entre los niveles de estrés y variables relacionadas con este entre hombres y mujeres, siendo las estudiantes las que mostraron mayores niveles de estrés (t(260.077)=-4.801, p£0.01, r=0.29). Además, también se hallaron diferencias en la elección de las estrategias de afrontamiento utilizadas por hombres y mujeres. En conclusión, los resultados del presente trabajo mostraron diferencias estadísticamente significativas entre los niveles de estrés de los estudiantes universitarios dependiendo de su género.  Abstract. Currently, the health crisis resulting from the appearance of COVID-19 has had a significant impact on the lives of the population, which has undergone many changes in a very short space of time. University students are one of the populations that have had to adapt the most to this pandemic context, which may have generated new stressful situations, affecting their mental health. Therefore, the main objective of this study was to analyse the levels of academic stress in this population, as well as to identify the main stressors, symptomatology associated with stress and the coping strategies adopted by each gender. The total study sample consisted of 351 university students (211 women) who were provided with the Systemic Cognitive Inventory for the Study of Academic Stress (SISCO) adapted to the context of the crisis by COVID-19. The results showed significant differences in stress levels and stress-related variables between men and women, with female students showing higher levels of stress (t(260.077)=-4.801, p£0.01, r=0.29). In addition, differences were also found between in the election of the coping strategies used by men and women. In conclusion, the results of the present study showed statistically significant differences between the stress levels of university students depending on their gender. Furthermore, the main stressors, stress-associated symptomatology and coping strategies adopted by each gender were identified.

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.
