“…This suggests that selective attention ability and cognitive processing speed can be considered to be positively related to better decision-making, better technical execution, better game reading, and greater efficiency in performing the task [10,[59][60][61][62]. These results are in line with previous studies that pointed out this phenomenon and suggest that soccer players with better cognitive functioning are better equipped to focus their attention on relevant stimuli, avoid shifting their interest towards elements that could interfere with the game, and handle information involved in the task more effectively, making them more successful [59,63]. Therefore, it would be interesting to implement cognitive training programs in the soccer players' preparation process.…”

The aim of this study was to analyze the relationships between cognitive functioning, physical fitness, and game performance in a sample of adolescent soccer players. Eighty-five boys from a soccer team in Rincon de la Victoria (Malaga, Spain), aged between 12 and 16 years, participated in the study. The D2 and Global-Local Attention (GLA) tests were used to evaluate selective and divided attention, respectively, and the Coding and Symbol Search tests of the Wechsler Intelligence Scale for Children (WISC-IV) were used for processing speed. To analyze physical fitness, the standing long jump test, speed test, and Course-Navette test of the Alpha-Fitness battery were used. Finally, the Game Performance Assessment Instrument (GPAI) was used to analyze sports performance in three vs. three small-sided games. The analyses showed that cognitive functioning was related to game performance. The results obtained suggest the importance of cognitive functions for performance in this sport.

“…For each epoch, we considered as outliers the channels with an amplitude absolute value above 75 µV and zeroed them. We selected this threshold based on meticulous visual inspection of the EEG according to previous studies [ 58 , 59 , 60 ]. Then, we detrended and z-scored each epoch, and we estimated the power spectral density (PSD) in several frequency bands (see Table 1 ).…”

The latest studies in virtual reality (VR) have evidenced the potential of this technology to reproduce environments from multiple domains in an immersive way. For instance, in stress relief research, VR has been presented as a portable and inexpensive alternative to chromotherapy rooms, which require an adapted space and are expensive. In this work, we propose a portable and versatile alternative to the traditional chromotherapy color-loop treatment through four different 360-degree virtual experiences. A group of 23 healthy participants (mean age 22.65 ± 5.48) were conducted through a single-session experience divided into four phases while their electroencephalography (EEG) was recorded. First, they were stressed via the Montreal imaging stress task (MIST), and then relaxed using our VR proposal. We applied the Wilcoxon test to evaluate the relaxation effect in terms of the EEG relative gamma and self-perceived stress surveys. The results that we obtained validate the effectiveness of our 360-degree proposal to significantly reduce stress (p-value = 0.0001). Furthermore, the participants deemed our proposal comfortable and immersive (score above 3.5 out of 5). These results suggest that 360-degree VR experiences can mitigate stress, reduce costs, and bring stress relief assistance closer to the general public, like in workplaces or homes.

“…We tagged the epochs above an amplitude of 75 µV as outliers and zeroed them. We selected this amplitude limit after visual inspection of the signals in accordance to prior studies (Cassani et al, 2017;Jeunet et al, 2020). Then, we detrended and standardized every epoch.…”

Recent studies have addressed stress level classification via electroencephalography (EEG) and machine learning. These works typically use EEG-based features, like power spectral density (PSD), to develop stress classifiers. Nonetheless, these classifiers are usually limited to the discrimination of two (stress and no stress) or three (low, medium, and high) stress levels. In this study we propose an alternative for quantitative stress assessment based on EEG and regression algorithms. To this aim, we conducted a group of 23 participants (mean age 22.65 ± 5.48) over a stress-relax experience while monitoring their EEG. First, we stressed the participants via the Montreal imaging stress task (MIST), and then we led them through a 360-degree virtual reality (VR) relaxation experience. Throughout the session, the participants reported their self-perceived stress level (SPSL) via surveys. Subsequently, we extracted spectral features from the EEG of the participants and we developed individual models based on regression algorithms to predict their SPSL. We evaluated stress regression performance in terms of the mean squared percentage error (MSPE) and the correlation coefficient (R2). The results yielded from this evaluation (MSPE = 10.62 ± 2.12, R2 = 0.92 ± 0.02) suggest that our approach predicted the stress level of the participants with remarkable performance. These results may have a positive impact in diverse areas that could benefit from stress level quantitative prediction. These areas include research fields like neuromarketing, and training of professionals such as surgeons, industrial workers, or firefighters, that often face stressful situations.
