Coronaviruses (CoVs) are a large family of respiratory viruses that can cause mild to moderate illness. The new variant COVID-19 has started to spread rapidly since December 2019, posing a new threat to global health. To counter the spread of the virus, the Italian government forced the population to close all activities starting from 9 March 2020 to 4 May 2020. In this scenario, we conducted a cross-sectional study on a heterogeneous sample (average age of 28 ± 12 years, 62.6% females) of the University of Naples Federico II (Italy). The aim of the study was to describe the lifestyle change in the university population during quarantine for the COVID 19 pandemic. Participants compiled an online survey consisting of 3 sections: socio-demographic data, dietary behaviours, physical activity habits and psychological aspects. The different results by gender are: 90.8% of females continued to work from home (81.9% were students); 34.8% increased their physical activity; and, only 0.8% prefer ready meals. Whereas, the same percentage of men continued to work from home (90%), but only 72.1% were students (p < 0.001 vs. females), only 23.9% increased physical activity (p < 0.001) and 1.7% favous ready meals. Our data shows that the male population was more affected by isolation and quarantine reporting more unfavourable behavioural changes.

Background: Physical exercise is a source of stress to the human body, triggering different ventilatory responses through different regulatory mechanisms and the aquatic environment imposes several restrictions to the swimmer, particularly regarding the restricted ventilation. Thus, we aimed to assess the acute ventilatory responses and to characterize the adopted breathing patterns when swimming front crawl at increasing intensity domains. Methods: Eighteen well-trained swimmers performed 7 × 200 m front crawl (0.05 m∙s⁻¹ velocity increments) and a maximal 100 m (30 s rest intervals). Pulmonary gas exchange and ventilation were continuously measured (breath-by-breath) and capillary blood samples for lactate concentration ([La⁻]) analysis were collected at rest, during intervals and at the end of the protocol, allowing the identification of the low, moderate, heavy, severe and extreme intensity domains. Results: With the swimming velocity rise, respiratory frequency (f_R), [La⁻] and stroke rate (SR) increased ([29.1–49.7] breaths∙min⁻¹, [2.7–11.4] mmol∙L⁻¹, [26.23–40.85] cycles; respectively) and stroke length (SL) decreased ([2.43–2.04] m∙min⁻¹; respectively). Oxygen uptake (VO₂), minute ventilation (VE), carbon dioxide production (VCO₂) and heart rate (HR) increased until severe ([37.5–53.5] mL∙kg⁻¹∙min⁻¹, [55.8–96.3] L∙min⁻¹, [32.2–51.5] mL∙kg⁻¹∙min⁻¹ and [152–182] bpm; respectively) and stabilized from severe to extreme (53.1 ± 8.4, mL∙kg⁻¹∙min^-1, 99.5 ± 19.1 L∙min⁻¹, 49.7 ± 8.3 mL∙kg⁻¹∙min⁻¹ and 186 ± 11 bpm; respectively) while tidal volume (V_T) was similar from low to severe ([2.02–2.18] L) and decreased at extreme intensities (2.08 ± 0.56 L). Lastly, the f_R/SR ratio increased from low to heavy and decreased from severe to the extreme intensity domains (1.12 ± 0.24, 1.19 ± 0.25, 1.26 ± 0.26, 1.32 ± 0.26 and 1.23 ± 0.26). Conclusions: Our findings confirm a different ventilatory response pattern at extreme intensities when compared to the usually evaluated exertions. This novel insight helps to understand and characterize the maximal efforts in swimming and reinforces the importance to include extreme efforts in future swimming evaluations.

The influence of biological maturity status on talent identification and development in youth soccer has been debated extensively. Alternative methods have thus recently emerged to estimate maturity status, such as the Pubertal Development Scale (PDS), but their relationship with physical capabilities of young soccer players still needs to be determined. The present study investigated the relationships of different PDS-derived pubertal status measures, chronological age, and relative age with selected performance variables in youth soccer. Sixty-one male soccer players were assessed for physical capabilities using field tests for sprinting, vertical jumps (countermovement jump, CMJ), intermittent high-intensity endurance, and repeated sprint ability. Chronological age was defined as the number of days since birth, and relative age was defined in terms of age quarters. PDS-derived measures of puberal status, otherwise, were determined as an average PDS score, a PDS category score, and a pubertal category. Chronological age, relative age, and measures of pubertal status were scarcely related (p > 0.05) to selected measures of soccer performance. Significant correlations were only found between different measures of pubertal status and the variable "work" in the CMJ test (range r = 0.33–0.36; p < 0.01) and between chronological age and CMJ height (r = −0.297; p = 0.02). The present results suggest that physical performance of young soccer players is poorly related to chronological age, relative age, and pubertal status. Potential effects of biological maturity status on physical capabilities may not be easily identifiable in a group of young soccer players narrowed in terms of chronological age and training status.

The present experiment sought to further understanding of the psychological and psychophysiological mechanisms underlying the effects of a single session of audio-guided meditation during moderate-intensity cycling exercise. Twenty-four healthy participants were recruited. A portable EEG device was employed to investigate the cerebral responses associated with the effects of meditation on exercise. Psychological measures were administered at three timepoints during the exercise bout. Two experimental conditions (endurance meditation [EM] and catastrophic meditation [CM]) and a control condition (CO) were administered. Participants were asked to exercise for 8 min (2 min of warm-up performed at 20% below the first ventilatory threshold + 6 min of exercise performed at the first ventilatory threshold) at 60 rpm. The EEG signal from frontal electrode sites was decomposed using Morlet Complex Wavelets, and event-related perturbation was calculated to investigate changes in beta frequency associated with the cycling phase. The results indicate that EM was sufficiently potent to ameliorate exertion and enhance affect to a greater degree than CO and CM. The neural mechanisms underlying the effects of EM appear to be associated with increased beta activity in the right frontal regions. The results of this study also indicate that exertional fatigue can be modulated through an alternative route that is not reliant upon the use of dissociative thoughts and does not require motivation to be up-regulated.

Background: Stigma is a pervasive, though understudied, psychosocial factor affecting people with multiple sclerosis. This review synthesizes the literature on the impact of perceived, enacted, and internalized stigma on psychological health and illness identity in PwMS. Methods: A comprehensive narrative review approach was adopted, integrating findings from peer-reviewed quantitative and qualitative studies. Databases including PubMed, PsycINFO, and Scopus were searched using combinations of terms such as “multiple sclerosis”, “stigma”, “internalized stigma”, “mental health”, and “illness identity”. Studies were included if they reported on stigma-related outcomes in PwMS, discussed psychological or identity variables, or examined interventions aimed at reducing stigma or enhancing adaptive identity. The analysis focused on thematic synthesis, identifying recurrent findings, mediating mechanisms, and clinical implications. Results: Stigma in MS is consistently linked to higher depression, anxiety, and lower quality of life. Internalized stigma disrupts illness identity, often fostering engulfment and rejection of the self. Psychological mediators—such as cognitive fusion, diminished self-compassion, and weakened sense of coherence—amplify these outcomes. Particularly vulnerable are individuals with progressive disease, severe disability, minority status, or limited social support. A recursive loop emerges: stigma triggers psychological distress, which increases stigma awareness and social withdrawal. In addition to traditional psychological interventions, several emerging approaches have shown promise in reducing internalized stigma and fostering adaptive identity integration. Conclusions: Stigma is a central factor in emotional suffering and identity fragmentation in PwMS. Integrative, narrative-informed, and culturally sensitive interventions are essential to reduce stigma and foster resilience. Future research should prioritize longitudinal, mixed-method approaches to develop effective, scalable solutions.

Objective: To investigate the effects of combining a Pilates program with photobiomodulation therapy (PBMT) in patients with chronic nonspecific low back pain (CNLBP). Methods: Thirty-eight adults with CNLBP were randomly assigned to two groups: Pilates exercise + active PBMT (PIL + PBMT) or Pilates exercise + sham PBMT (PIL + SHAM). Both groups performed an 8-week mat Pilates program and received PBMT on their lumbar muscles 10 min before and after each session. The following variables were assessed before and after intervention: peak pain intensity, postural balance (i.e., center of the pressure [A-COP], velocity anteroposterior [Vel AP], and velocity mediolateral [Vel ML]), perceived disability (i.e., Oswestry Disability Index [ODI] and Roland Morris Disability Questionnaire [RMDQ]), and pain-related fear of movement (i.e., Tampa Scale of Kinesiophobia [TSK], Fear Avoidance Beliefs Questionnaire [FABQ], and Pain Catastrophizing Scale [PCS]). Results: Postural balance variables showed no statistically significant differences (p > 0.05) across time or between groups. The groups showed similar (p < 0.05) reductions in peak pain intensity, ODI, RMDQ, and PCS scores, but no statistically significant difference (p > 0.05) in TSK and FABQ scores. Conclusion: The mat Pilates program reduced peak pain intensity, perceived disability, and pain catastrophizing in adults with CNLBP, but PBMT had no additional effect on these variables. Mat Pilates alone or combined with PBMT was not able to improve postural balance.
