    The objective of this study was to explore the effect of COVID-19 and Ramadan on physical activity (PA) and burnout in teachers and the relationship between them. A total of 57 secondary school teachers from public education centers participated in the present study. They were aged between 29 and 52 years. To determine the effect of Ramadan and COVID-19 on PA and burnout, participants completed the online questionnaires before COVID-19, one week before Ramadan and during the second week of Ramadan. The International Physical Activity Questionnaire-BREF and the Maslach Burnout Inventory-Human Services Survey were used to assess PA intensities and burnout, respectively. The data revealed that total PA (p p p p p p p p p < 0.05). In addition, low to high correlations were observed between PA intensities and burnout subscales, except for the correlation between depersonalization and all PA intensities. In conclusion, Ramadan intermittent fasting along with PA was highly recommended for teachers and the general population to improve positive emotions and general health

    The present study aimed to verify the effect of a warm-up protocol with and without facemask-use on cognitive function. The sample was composed of 17 healthy, non-smoking physical education students (age = 17.6 years, height = 1.71 m, and body mass = 69.7 kg). They were randomized to perform 15 min of warm-up exercises, while wearing a cloth facemask (EXP) or no mask (CON) on two separate occasions, with at least 48-h separating conditions. Rate of perceived exertion (RPE) and d2 Attention assessment were used to verify cognitive function, using a repeated measures general linear model. The warm-up improved cognitive abilities and the results demonstrated significant differences between the EXP vs. CON groups in post-concentration performance (186.06 % 15.47 EXP-score vs. 178.12 % 13.66 CON-score), post the total number of errors (23.47 % 14.50 EXP-frequency 4.7 % 0.85 CON-index). Wearing a cloth facemask caused positive effects on cognitive function. This data suggests that wearing a cloth facemask during warm-up may stimulate/improve the cognitive function

    The relative contributions of ACE genotypes on personality traits in Tunisian athletes

    BACKGROUND: The present study attempted to test whether the ACE genotypes can be associated with particular personality traits that can be potentially used as predictors of athletic performance. Eighty seven track and field athletes (47 males, 40 females; aged 20.55±2.22) competing at an international level, voluntarily participated in this study. The athletes were prospectively classified into two groups according to their genetic polymorphism to physical efforts: endurance group (allele I, N.=48) and power group (allele D, N.=39). This genetic predisposition has been granted with athletes’ specialty. METHODS: Personality trait was assessed before competition and the ACE gene polymorphism was examined by polymerase chain reaction. RESULTS: The results revealed strong relationships between score performances and psychological constructs. Using allele I (related to the endurance), calmness explained 31% of the variance, and when sociability was added to the equation, 43% of the variance of score performance was further explained. On the other hand, nervousness explained 23% of the variance using allele D (related to the power), and when aggressiveness was added to the equation, 34% of the variance of score performance was then explained. CONCLUSIONS: The current study is the first to interpret the relationship between the ACE gene and personality traits and has provided evidence that the distance runners and power athletes exhibited different personality profiles associated with their ACE I/D polymorphism predisposition.Scopu
