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.

Acute physical exercise works as an activator of the responses of the human organism to stress. This is based on the activation of the hypothalamic–pituitary–adrenal (HPA) axis, affecting physical, physiological and psychological levels. This study aimed to analyse the effects of a single bout of high-intensity resistance exercise on cognitive-behavioural responses: visuo-spatial path learning and memory, as well as physiological responses (salivary cortisol levels). Nineteen healthy male military-trained powerlifting subjects were tested in a within-subject design on two experimental days with an interval of 48 h. The stress and cognitive variables were measured by cortisol levels and Ruff–Light trail-learning test (RULIT) test scores, respectively. The results showed the immediate influence of acute exercise on cortisol, with significantly higher cortisol levels found in subjects after completion of the acute resistance exercise. In addition, this study found a significant deterioration of memory and learning ability after a dose of intense resistance exercise. In conclusion, the study highlights the relative effects of resistance exercise on cortisol and cognitive performance depending on the intensity and type of the exercise, the moment of measurement and the cerebral areas implicated.

Background: Golf swing performance in medium- to high-handicap players must be reliably measured to use this variable in both research studies and in applied settings. Nevertheless, there are no studies published on this topic and test–retest evidence is only available for low-handicap players. The aim of this study was to determine the number of attempts necessary to obtain a reliable measurement protocol for swing performance variables in medium- to high-handicap players. Methods: Ten amateur players (55.67 (13.64) years, 78.4 (11.4) kg, 1.75 (7.95) m) took part in a test–retest study in two experimental sessions one week apart. In each one, fifteen swings with a six iron and a driver were evaluated with a 3D Doppler tracking golf radar. Results: The results showed that variables related to side carry could not be reliably measured in medium- to high-handicap players in only fifteen trials (ICC < 0.26, SEM > 12.05 m and MDC > 33.41 m). The rest of the performance variables related to the club and ball trajectories could be reliably measured with a 3D Doppler radar with between seven and ten swings. Conclusions: At least seven swings are recommended for the driver and ten for the six iron to measure golf swing performance.

Introduction: The main objective of this study was to determine the rate of auditory concurrent feedback that best enhanced the learning of a continuous postural task in adolescents. Material and methods: A sample of thirty adolescents (13 to 14-years old) was used, who were assigned to three groups: i) control group (CG); ii) 100% auditory feedback group and iii) 67% auditory feedback group. The subjects performed a pre-test, practice, post-test and a retention (24 hours after the practice). In the postural control task subjects were instructed to remain on a seesaw (unstable in anteroposterior position) and keeping it as level as possible. Results: The results demonstrated that concurrent auditory feedback did not enhance the performance of the continuous postural task, although concurrent auditory feedback (both 100% and 67% rates) caused changes to the postural control strategies. Conclusions: From this it was concluded that 100% and 67% concurrent auditory feedback are more recommendable than no-feedback in adolescents’ postural control learning.
