Background: The Italian government promoted social distancing, in which the suspension of any social event, suspension of all activities practiced in gyms, sports centers and their closure was ordered. The social distancing in the school environment and the use of strategies to limit viral infection are not very compatible with group motor activity and team sports. The aim of this study is to verify the effectiveness of a CrossFit program in order to mitigate the deficits in fitness caused by COVID-19 prevention measures and to evaluate the effects on self-efficacy in a group of young adolescents. Methodsː 30 healthy participants were randomly allocated into an intervention group (IG) that performed the 8 weeks CrossFit training program or control group (CG). Physical fitness tests (i.e., Squat, push-up, lunge, and 20 m run) and psychological measures Regulatory Emotional Self-Efficacy scale (RESE) were performed at baseline and after 8 weeks. Resultsː After 8 weeks, the intervention group showed significant improvements for all fitness tests (p < 0.0001). Additionally, higher scores for the RESE negative and positive (p < 0.0001) scales were found in the intervention group. No statistical differences were found in the control group except for the push up test. Conclusionsː the 8-week CrossFit intervention program could positively affect the general physical well-being and improve the emotional perceived self-efficacy in healthy adolescents.

Mobile devices (i.e., smartphones and tablets) have acquired important functions in both interpersonal and individual spheres. For this reason, they can cause a true dependence for the young people. Moreover, prolonged periods of cognitive activity induce mental fatigue, a psychobiological state which influences the performances in team sports. PURPOSE:The purpose of this study was to assess the effects of prolonged use of smartphones on physical and technical performance of young footballers. METHODS:In total, 16 young male footballers (15.0 ± 1.1 years) were randomly assigned to two studies, Study 1 (S1, n=8) or Study 2 (S2, n=8), in which the Yo-Yo Intermittent Recovery Test level 1 and the Loughborough Soccer Passing Test were performed, respectively. The soccer-specific physical and technical performance was assessed for S1 and S2. In both studies, the participants underwent to mental fatigue through the use of smartphones (Brain It On App) for 30 minutes, and to the control condition (normal activities) after at least 48 hours. A crossover study design and a paired t-test (p<0.05) were used.RESULTS: S1 performed shorter running distances in the state of mental fatigue than under the control condition (1610 ± 135 vs. 1780 ± 249 m, Δ -10.56%, p = 0.046). In addition, mental fatigue significantly increased the performance time in S2 compared with the control condition (51 ± 6 vs. 43 ±2.2 s, Δ +15.7%; p = 0.003). CONCLUSION:Our findings suggest that prolonged use of smartphones, which causes mental fatigue, can reduce the physical and technical performance of young footballers. Therefore, it is necessary to educate to the conscientious use of technology.

The purpose of this randomized controlled study was to investigate the effects of a 12-week coordinative ability training program on adolescents’ cognitive functioning, using evaluation tests of visuospatial perception, attention, and working memory. We randomly assigned 60 public school students (14–15 years) to either an experimental coordinative abilities training (∼40 min twice/week) group (n = 30) or a control group (n = 30) who received general psycho-physical wellness training (∼40 min., twice a week). At baseline and after training we used two standardized motor tests and a single cognitive measure (Corsi’s Block-tapping test) to assess students’ visuospatial perception, attention, and working memory. We found a significant Time x Group interaction for the Throwing and Catching Test and Corsi’s Block-Tapping test, reflecting a meaningful experimental group improvement (p &lt; 0.001), and there were no significant pre-post changes found in the control group. Thus, a 12-week program of coordinative abilities was able to improve not only coordination skills but aspects of cognitive functioning relevant to academic achievement.

Background and objectives: Lymphoma patients experience a psychological and physiological decline that could be reversed by exercise. However, little is known about the effects of the exercise on psychological and physical fitness variables. Therefore, the purpose of this longitudinal study was to assess self-efficacy, fatigue and physical fitness before and after an eight-week exercise intervention. Materials and Methods: Thirty-six participants (54.4 ± 19.1 years) performed a supervised exercise program (~60 min, 2d·wk−1). Each session included a combined progressive training of cardiorespiratory, resistance, flexibility and postural education exercises. Self-efficacy and fatigue were measured with the Regulatory Emotional Self-Efficacy scale and 0–10 rating scale, respectively. Physical fitness was assessed with the body mass index, lower back flexibility, static balance, muscle strength and functional mobility. Results: Adherence to exercise was high (91.2% ± 4.8%) and no major health problems were noted in the patients over the intervention period. At baseline, significant differences were found between Hodgkin’s lymphoma and non-Hodgkin’s lymphoma patients by age and all dependent measures (p < 0.05). Fatigue significantly decreased and the perceived capability to regulate negative affect and to express positive emotions improved after exercise (p < 0.001). Significant improvements were found for body mass index, trunk lateral flexibility, monopodalic balance, isometric handgrip force and functional mobility (p < 0.001). Fatigue was significantly correlated with handgrip force (r = −0.56, p < 0.001) and functional mobility (r = −0.69, p < 0.001). Conclusions: The supervised exercise program improved psychological and physical fitness without causing adverse effects and health problems. Therefore, exercise to improve fitness levels and reduce perceived fatigue should be considered in the management of lymphoma patients.

The purpose of the present study was to monitor any improvement in orienteering skills attributable to acquiring a better mental representation of space. Two groups were examined: the experimental group, who attended 6 mo. of orienteering lessons, versus the control group, who did jogging training instead. Each group, consisting of 20 children, was tested on the Corsi Block-tapping Test, run Forward and Backward, and the Star-Butterfly Test. Pre- and post-tests were administered. In the experimental group, scores increased in mean complexity from pre- to post-test on the Forward and the Backward Corsi tests, while on the Star-Butterfly Test both time and mistakes had decreased after the training. In the control group, mean complexity and Star-Butterfly Test scores were unchanged from pre- to post-test. These results showed that after continual training in orienteering techniques, the orienteering group was able to remember and repeat sequences of events with greater precision than before the training, while these skills were unchanged in the control group after training in jogging.

Body image is a multidimensional construct encompassing how we perceive, think, feel, and act toward our bodies and lies on a continuum from healthy body perceptions to unhealthy body perceptions. Previous researches suggest that adolescent girls experience higher levels of body dissatisfaction than do their male counterparts. Therefore, the aim of this research was to investigate on gender differences concerning the perceived body dissatisfaction and uneasiness by adolescents and the role played by the physical education in the process of positive development of the mental representation of the corporeity. 100 students (14-15 years) participated voluntarily in the study and were assigned to trained group (n = 50; 25M, 25F) regularly practicing sports outside the school hours, or untrained group (n = 50; 25M, 25F) did not practice any extracurricular physical activity in the period before the study. After anthropometric measurements (BMI), two standardized psychological tests to assess the degree of personal satisfaction towards their body were administered (i.e., Body uneasiness test (BUT) and contour drawing rating scale (CDRS)). BUT and CDRS scores were significantly lower for total trained group and trained females (p < .05). Also, total trained group and males and females trained showed a significant lower BMI (p < .05), whereas no significant difference was observed between the untrained and trained males for BUT and CDRS. Findings showed a better bodysize perception and a smaller body uneasiness by trained adolescents. Moreover, girls showed anyway a greater dissatisfaction and uneasiness with the external appearance compared to their male counterpart.

The purpose of this randomized controlled study was to investigate the efficacy of an 8-week exercise programme conducted in e-learning mode on high school students’ academic performance. The aim was to examine the changes in physical fitness and learning outcomes during the enforced period of lockdown caused by outbreak of the second wave of COVID-19 pandemic and the closure of schools in Italy. Thirty high-school students (14–15 years) were randomly assigned to an experimental group (n = 15) that performed an at-home workout programme (~60 min., twice a week), or a control group (n = 15) who received only a regular programme of theoretical lessons where no practice takes place. Both groups were synchronized in real-time with the physical education teacher. In order to assess students’ starting level and significant changes reached, at baseline and after training, a battery of standardized assessment motor tests (Standing long jump test, Harvard step test, sit and reach test, and butt kicks test), and an academic achievement test (Amos 8–15) were administered. In comparison to the control group at baseline and the end of the programme, the experimental group reported considerable improvements in motivation and concentration, significant anxiety reduction, and an increase in capacity to organize studying and to be more flexible. Moreover, it was possible to observe the efficacy of the workout to improve learning ability among practicing students (p < 0.001). No significant changes were found in the control group. The results suggest that a school-based exercise programme conducted online could be a powerful approach in order to achieve the best academic outcomes and for improving students’ physical fitness as well as their cognitive health.

Several studies have been conducted to find at least an association between physical activity (PA)/ physical exercise (PE) and the possibility to modulate the gut microbiome (GM). However, the specific effects produced on the human GM by different types of PA/PE, different training modalities, and their age-related effects are not yet fully understood. Therefore, this systematic review aims to evaluate and summarize the current scientific evidence investigating the bi-directional relationship between PA/PE and the human GM, with a specific focus on the different types/variables of PA/PE and age-related effects, in healthy and unhealthy people. A systematic search was conducted across four databases (Web of Science, Medline (PubMed), Google Scholar, and Cochrane Library). Information was extracted using the populations, exposure, intervention, comparison, outcomes (PICOS) format. The Oxford Quality Scoring System Scale, the Risk of Bias in Non-Randomized Studies of Interventions (ROBINS-I) tool, and the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies were used as a qualitative measure of the review. The protocol was registered in PROSPERO (code: CRD42022302725). The following data items were extracted: author, year of publication, study design, number and age of participants, type of PA/PE carried out, protocol/workload and diet assessment, duration of intervention, measurement tools used, and main outcomes. Two team authors reviewed 694 abstracts for inclusion and at the end of the screening process, only 76 full texts were analyzed. Lastly, only 25 research articles met the eligibility criteria. The synthesis of these findings suggests that GM diversity is associated with aerobic exercise contrary to resistance training; abundance of Prevotella genus seems to be correlated with training duration; no significant change in GM richness and diversity are detected when exercising according to the minimum dose recommended by the World Health Organizations; intense and prolonged PE can induce a higher abundance of pro-inflammatory bacteria; PA does not lead to significant GM α/β-diversity in elderly people (60+ years). The heterogeneity of the training parameters used in the studies, diet control, and different sequencing methods are the main confounders. Thus, this systematic review can provide an in-depth overview of the relationship between PA/PE and the human intestinal microbiota and, at the same time, provide indications from the athletic and health perspective.
