Urban green spaces (UGSs) are increasingly recognised as critical infrastructure for mitigating climate extremes and promoting public health; indeed, the microclimatic mechanisms through which vegetation structure translates into measurable improvements in human comfort at the neighbourhood scale are of significant interest, particularly in the context of new urban developments. This study examines the cooling effects of an urban redevelopment project in the Marconi district of Imola, Italy, using ENVI-met (Version 6.0.0, ENVI-met GmbH, Essen, Germany) simulations to compare ex ante (current) and ex post (planned) scenarios under extreme heat conditions. Physiological Equivalent Temperature (PET) was computed at the pedestrian level for both standard adult and elderly models to assess spatial patterns of thermal comfort. The results demonstrate that tree canopies are the primary determinant of local cooling, with newly planted trees reducing PET by up to 3.5 °C at the core of the regenerated block and by 1–2 °C along adjacent pavements, while grass and low vegetation provided negligible mitigation. However, new buildings generated localised warming bands of 0.5–2 °C along façades, revealing a trade-off between densification and outdoor liveability. Elderly populations experienced slightly stronger thermal stress near buildings, highlighting spatial concentrations of vulnerability. These findings reinforce the need to prioritise tree planting and canopy management as core climate adaptation strategies, while simultaneously addressing near-building heat accumulation through integrated design approaches such as façade greening and ventilation preservation. The study demonstrates the value of spatially explicit microclimate simulation for evidence-based urban planning, contributing to the development of sustainable and liveable urban environments.

Background:A growing body of evidence suggests that physical activity during pregnancy may have significant health benefits. Self-reported questionnaires may represent an important instrument for gathering information and quantifying the amount of physical activity that women engage during pregnancy. In this study we analyzed the reliability and validity of the Italian version of the Pregnancy Physical Activity Questionnaire. Methods:The reliability and construct validity of the Italian Version of the Pregnancy Physical Activity Questionnaire was analyzed in a sample of pregnant women. Intraclass correlation coefficients (ICCs) were calculated to investigate the test-retest reliability of the Italian Version of the Pregnancy Physical Activity Questionnaire scores at baseline and after 1 week. Intraclass correlation coefficients >0.70 were considered to denote an adequate reliability. Validity was assessed using Spearman's rank order correlation coefficients between the Italian Version of the Pregnancy Physical Activity Questionnaire scores and the equivalent measures obtained by accelerometers. Coefficients (ρ) >0.50 were considered adequate for construct validity. Results:The test-retest analysis revealed an adequate reliability for sedentary (Intraclass correlation coefficient = 0.785), moderate (Intraclass correlation coefficient = 0.751), and vigorous physical activity (Intraclass correlation coefficient = 0.931), while lower reliability was found for total (Intraclass correlation coefficients = 0.689) and light physical activity (Intraclass correlation coefficients = 0.632). All Spearman's rank correlation coefficients between the Italian Version of the Pregnancy Physical Activity Questionnaire and the accelerometers measures were <0.50 and non-statistically significant. Conclusion:The results of this study showed that the Italian Version of the Pregnancy Physical Activity Questionnaire has almost adequate reliability, while construct validity, based on correlation between Italian Version of the Pregnancy Physical Activity Questionnaire scores and accelerometer data, is very low. Still, the Pregnancy Physical Activity Questionnaire may represent a useful tool to capture daily life activities of pregnant women.

It is widely known that regular physical activity (PA) can provide substantial benefits to health and well-being. Green spaces and supervised PA interventions by trainers are also effective factors in increasing participation in PA. Hence, the “Moving Parks” project conducted by the Municipality of Bologna, Italy, emerged out of necessity. This study aimed to measure the effectiveness and the reasonableness of the project by investigating the effects of Moving Park intervention on participants’ well-being and motivations for future PA engagement. Two questionnaire surveys before and after the participation in the project were administered and 138 valid results were analyzed. The results suggest a significant improvement in well-being after participating in the outdoor sessions provided by the present study; the most possible motivation which drives to practice PA is the feeling of guilt, especially for females. Overall, the continuation of the “Moving Parks” project is rewarding to the residents, reducing stress, and improving wellbeing.

Elderly patients with femoral fractures need specific rehabilitation after surgery that aims to improve their self-reliance and life quality, reducing their mortality rate. Although worsening patient body composition increased the risk of an unfavourable prognosis, it remains unclear whether evaluating bioelectrical impedance analysis (BIA) parameters can predict any functional recovery. A longitudinal design was conducted on 45 elders (84.59 ± 7.18 years, 75.6% female) who underwent femoral surgery to examine BIA features as rehabilitation biomarkers. The patient’s body composition, assessed by anthropometry and bioimpedance analysis (BIA), and self-reliance were evaluated three times during follow-up in both healthy and surgical lower limbs. The ANCOVA test, adjusted for gender and side of surgery, found improvements in daily living activities, while only thigh circumferences decreased over time. Regarding the BIA, the surgical leg showed a wider decrement in bioelectrical resistance (R), whereas the bioelectric reactance (Xc) exhibited similar trends. Females who underwent surgery on their dominant leg showed significant changes (p < 0.001) in bioimpedance vectorial analysis (BIVA), with a linear trend from baseline to postoperative time, while males exhibited beneficial variations only between baseline and time 2 (p < 0.01). Geriatric patients exhibit characteristic traits that require additional attention. BIA may be a feasible and non-invasive method for monitoring patient prognosis and reducing national health system costs.

In the context of rising mental issues due to various modern challenges, this study examines the relationship between physical activity (PA) and subjective well-being (SWB) among residents of Bologna, Italy. Using a cross-sectional design, data were collected from a representative sample of adults aged from 20 to 79. PA levels, including moderate physical activity (MPA) and vigorous physical activity (VPA), were measured using a questionnaire survey, while the Warwick–Edinburgh Mental Well-Being Scale assessed SWB. The data analysis involved descriptive statistics, chi-square tests for sex differences in categorical variables, two-way ANOVA for age and sex interactions on continuous variables, and hierarchical regression analyses to examine relationships between SWB and MPA/VPA while controlling for covariates, including a composite analysis of total physical activity hours. Our analysis demonstrated that PA positively affected people’s mental health. Participants engaging in PA levels recommended by the WHO exhibited markedly better values in SWB than those who did not reach these thresholds. The study identified age, health issues and work situation as significant sociodemographic and lifestyle factors influencing SWB. Notably, no significant benefits were observed when MPA and VPA were included in a unified model, while the total weekly duration of PA still exhibited a dose–response relationship with SWB. This study underscores the importance of PA in enhancing SWB and highlights the need for tailored PA guidelines considering demographic variations. The findings advocate for future longitudinal studies to elucidate the causal relationships and refine PA recommendations for diverse populations.

Rapid urbanisation has highlighted the importance of urban green spaces (UGS) in promoting environmental sustainability and human wellbeing, yet the gap between urban planning practices and community preferences remains a significant challenge. This study investigated residents’ perceptions and attitudes towards UGS in a neighbourhood of an Italian city (Quartiere Marconi, Imola), focusing on understanding both the strengths and limitations of existing public green spaces from users’ perspectives. Through a comprehensive questionnaire survey of 126 residents, we examined the associations between socio-demographic characteristics and four aspects of UGS utilisation: visiting purposes, barriers to visits, satisfaction levels, and suggestions for improvement. Chi-square tests were conducted to identify significant relationships. The results indicate that life stage, rather than scattered socio-demographic factors, plays a crucial role in shaping UGS perceptions and usage patterns. Particularly, the 31–45 and 46–60 age groups, characterised by family-caring and career responsibilities, showed distinct preferences for social activities, while individual users focused more on nature enjoyment. Although accessibility was generally sufficient, satisfaction levels varied significantly based on living arrangements, with families emphasising facility-related issues and individual users prioritising natural features. These findings suggest that successful UGS planning requires attention to both high-quality natural elements and user-oriented facilities to meet the diverse needs of different life stages. This study represents the preliminary phase of a project, which concerns the redevelopment of the area under study, in order to create a more inclusive and high-quality UGS, taking into account the needs of the resident population.

With the rapidity of urbanisation, concerns about citizens’ mental wellbeing issues are on the rise, and simultaneously, the issue of land use conflicts is becoming increasingly prominent. As a nature-based solution, the role of urban green space has been continually emphasised in the past decade. In urban areas facing scarce land resources, improving the quality of green spaces appears to be an important approach. This review aimed to systematically elaborate the studies regarding the associations between urban green space (UGS) qualities and mental wellbeing, following the Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twenty-two articles were included, and most of them had a cross-sectional design. From the analysis of the data, it emerged that the definition of the quality of green space is heterogeneous. Natural elements, particularly vegetation diversity and water features, consistently showed positive associations with mental wellbeing, while the effects of spatial features like accessibility showed mixed results. The impact of facilities and amenities appeared more complex, with their benefits heavily dependent on the design and maintenance. More evidence is needed to determine the mental wellbeing benefits of maintenance and the development of facilities and amenities for UGSs. In addition, the assessment of mental wellbeing relied on various self-reported scales, with different scales targeting different aspects. Instrumental measurements were rarely employed. Future research should employ more rigorous experimental methods and standardised quality assessment tools.

In recent decades, extensive evidence has indicated that green spaces and physical activity (PA) are associated with mental health, while limited research has explored the combined effects of supervised PA in urban green spaces. To address the research gap, this study examines whether supervised PA within green spaces improves mental health among middle-aged adults (45–65 years) through a quasi-experimental longitudinal study developed as part of the “Moving Parks” project in Bologna, Italy. Using the Italian version of the Warwick–Edinburgh Mental Well-being Scale (WEMWBS), mental health was measured at pre- and post-assessment. A total of 340 participants (258 intervention, 82 control) were included in the study. The effects of intervention, group assignment, and their interaction on mental health scores were analysed using a two-way repeated measures ANOVA. No significant differences in mental health improvements were observed between the intervention group and control group. The results indicated significant main effects of time on total WEMWBS scores and several subscales such as optimism, usefulness, energy, and cheerfulness, but these changes were not significantly influenced by group assignment. The only significant group-by-time interaction was found in perceived usefulness. These findings do not provide conclusive support for the hypothesised benefits of the supervised PA intervention. Possible explanations include seasonal variation, baseline or ceiling effects, and the potential limitations of the WEMWBS in detecting short-term psychological changes. Future research should consider extending intervention duration, improving group comparability, and employing more sensitive assessment tools to better evaluate the mental health impact of green space–based PA programmes.

Background: This study aimed to investigate the association between Affective Exercise Experiences (AEEs), environmental factors, and adherence to a structured public health exercise initiative. Methods: A prospective experimental design was employed in a primary care setting within green parks in a community in Northern Italy. Community-dwelling individuals who participated in a 15-week outdoor exercise program were recruited. Participants engaged in 43 low-to moderate-intensity outdoor exercise sessions, held three times a week from May to July 2022, with each session lasting 60 min. A total of 68 participants (mean age: 64.6 ± 8.6 years) completed the questionnaires. Results: A causal analysis revealed a small but significant positive effect of AEEs on adherence, with higher AEE scores associated with an increased likelihood of attending exercise sessions. The predictive model identified a combination of AEE scores, environmental temperature, distance from the exercise site, and weekday as significant predictors of adherence. Conclusions: This study highlights the importance of AEEs, as well as environmental and demographic factors, in predicting adherence to structured exercise programs. The findings suggest that fostering positive affective experiences related to exercise could enhance adherence, particularly among older adults.

Background: High-intensity interval training (HIIT) is one of the most debated methods involving several parameters that could be modulated, but the long-term adaptations it induces are still unclear. This investigation aimed to evaluate the efficacy of running and whole-body exercises with high-intensity (>80% heart rate) short intervals (30 s) in body composition and physical performance and compare the effects between groups with active (AR) or passive recovery (PR), both in males and females. Methods: Eighteen trained young adults (55.56% ♀) were randomly allocated to the PR (n = 9, 23.09 ± 2.56 years, 163.69 ± 9.88 cm, 68.96 ± 14.62 kg) or AR (n = 9, 22.05 ± 1.54 years, 170.61 ± 11.5 cm, 68.78 ± 12.45 kg) group. Both groups performed eight weeks of HIIT, with an equal progression, training, and volume load (TL: F = 1.55, p = 0.214; VL: F = 0.81, p = 0.505). Body fat (BF), fat-free mass (FFM), upper and lower limb fat (UFI, LFI) and muscle areas (UMA, LMA), handgrip strength (HGS), power (countermovement jump, CMJ), agility (5-0-5), and maximal oxygen consumption (V˙O2p) were tested before and after treatments. Results: The proposed HIIT reduced BF by 9.57% and increased FFM by 2.09%. Females reported better adaptations in LMA (8.34 times higher than males), while both sexes’ upper limb mass distribution was better affected by PR (♀: UFI g = 1.851, 95% CI: 0.51, 3.14; ♂: UFI g = 2.456, 95% CI: 0.336, 4.487). Concerning conditioning, the protocol increased V˙O2p by 6.47%. Females showed better adaptations in CMJ (RR = 1.8), while males showed better adaptations in agility (RR = 3.76). The interaction effects were significant for PR females (right = +6.28%; left = +9.28%) and for AR males (right = +19.21%; left = +19.04%) in HGS. Conclusions: Short-interval HIIT with different exercise recovery types may be a practical solution in training where several physiological improvements are needed. Coaches and trainers can take advantage of the versatile nature of HIIT, relying on desired movement patterns and long-term responses in both male and female individuals.

Aim It is important to promote healthy lifestyles in youth through initiatives in school, which is a preferred setting to implement health-related interventions also targeted at families to be more effective. This study aimed to synthesise school-based interventions including homework and extracurricular activities for the promotion of healthy lifestyles, especially healthy nutrition and physical activity, in children and adolescents. Methods This systematic review was conducted according to the PRISMA guidelines. Quality assessment was performed using the Cochrane Tool for Quality Assessment for randomized and non-randomized control trials, while the STROBE (Strengthening the Reporting of Observational studies in Epidemiology) guidelines were used for observational studies. Results From the 1356 studies identified, eight were included. Across studies, a significant effect was found in increasing fruit and vegetable consumption and reducing snack and sugar intake, while no effect was found for moderate to vigorous physical activity (MVPA) unless for light PA (LPA) and step counts. The results of BMI and waist circumference are still unclear after performing a meta-analysis of three studies. Conclusion School-based interventions including homework and extracurricular activities were shown to improve nutritional behaviour, step counts, and LPA. Despite some statistically significant results, the effects of BMI and waist circumference are still unclear. Further studies are needed to demonstrate that these intervention s can represent an effective strategy for obesity prevention.

Age-related decreases in endurance performance are well known. However, several researches have been carried out on octogenarian athletes, who achieved high performance in some endurance sports. This case report aimed to discuss exercise capacity, body composition and the cardiovascular and common risk factors of an 81-year-old man with a high level of physical activity. The man had a body mass index of 25.59 kg/m2 with a high percentage of skeletal muscle mass (79%). Maximal oxygen uptake was 39.5 mL/min/Kg and oxygen pulse was 18.7 mL/beat showing an excellent exercise capacity. Heart and pulmonary functions were optimal for his age. Bioelectrical phase angle was higher than the average values for his age and gender. Physical activity carried out continuously is confirmed a predictor of healthy state in elderly age, however it is mandatory that master athletes carry out periodic checks of their state of health and monitor vital parameters during intense training.

Physical inactivity, a leading risk factor for chronic diseases and premature death, is prevalent worldwide. This study focuses on participant profiles and factors influencing continued participation and physical activity (PA) levels in the "Moving Parks" PA intervention in Bologna, Italy. This intervention offers free group activities in city parks during the summer. A questionnaire was administered to participants in 2022, gathering data on socio-demographic information, chronic diseases, participation in previous iterations, and PA levels. Out of 596 respondents, 85% were women, and the average age was 50. About 56% held a university degree, and 73% exercised regularly in the winter. Continuous participation was linked to older age, higher education, and chronic conditions. Prior participation predicted higher winter PA levels. Notably, the majority of participants were educated, physically active women. While the project continually engages individuals with higher education and chronic conditions, it needs further tailoring to reach less represented populations.

Body image perception includes body size assessment, body desirability estimation, and perceptions concerning one’s own body shape and size. Adolescence is a period of intense and prompt physical transformation, which changes the perception of one’s body. This represents a critical period for the development of body image. Therefore, the present cross-sectional study aimed to evaluate body image perception and investigate the relationships between it, weight status, sex, and physical activity in a sample of high school students living in Italy. General demographic information and details about physical activity were collected. Body image perception was measured with a body silhouette and two indexes were calculated: the FID (Feel minus Ideal Discrepancy) to evaluate the discrepancy between the perceived current figure and the ideal figure; and the FAI (Feel weight status minus Actual weight status Inconsistency) to observe improper perception of weight status. In addition, body shape concerns were evaluated with the Body Shape Questionnaire (BSQ), in which participants reported the frequency of experiencing negative thoughts about their body shape in the last four weeks. Two hundred and four students were included in the study (155 = female, mean age = 17.13 ± 1.70; 49 = male, mean age = 17.25 ± 1.69). Females felt more concerned about body shape than males (χ2 = 11.347, p = 0.001). Distinctions emerged in terms of body mass index, the scores of Feel minus Ideal Discrepancy (FID), Feel weight status minus Actual weight status Inconsistency (FAI), the Body Shape Questionnaire (BSQ), and of the silhouette mean comparisons due to sex, weight status, and PA interaction effects (p < 0.001). Additionally, 94% of the BSQ variability could be explained by sex, weight status, and PA. Although no direct effects were observed on body image perception, healthy habit promotion, such as physical activity, could positively affect adolescent lives.

Regular physical activity (PA) is protective and reduces disease burden but remains a challenge for pregnant women (PW). According to the World Health Organization (WHO) guidelines, PW without contraindications should practice 150 min of moderate PA per week. Nonetheless, PA levels are concerningly low among PW. The aim of this study was to investigate PW's and midwives' perceptions regarding PA and recommended guidelines, and use this information to inform future health promotion strategies. We recruited 10 PW and 10 midwives to participate in online focus groups conducted between July 2020 and April 2021. Focus group probes and data analysis were guided by the COM-B (capability, opportunity, motivation-behaviour) framework. The majority of the sample had already practised PA, recognized the importance of PA during pregnancy, and considered the WHO guidelines reasonable. Notwithstanding, PW wanted more specific instruction on PA and desired opportunities to practice. Additional barriers reported by PW included low self-efficacy and lack of motivation. Midwives considered the lack of specific knowledge and confidence in managing PA as the main obstacles. The current findings suggest that PW and midwives need specific training in PA to overcome both psychological and physical barriers. Midwives play a vital role in educating and encouraging PA among PW.

Background & aims: The bioelectrical impedance vector analysis (BIVA) represents a qualitative analysis of body composition. The vector, defined by resistance (R) and reactance (Xc) standardized by stature, can be evaluated compared to the 50%,75%, and 95% tolerance ellipses representative of the reference populations. The tolerance ellipses for healthy adults have been provided in 1995 and were developed by mixing underage, adult, and elderly subjects, possibly misrepresenting the actual adult population. The current multicentric, cross-sectional study aimed to provide new tolerance ellipses specific for the general adult population and as a secondary aim to present centile curves for the bioelectrical phase angle. Methods: R, Xc, and phase angle were measured in 2137 and 2230 males and females using phase-sensitive foot-to-hand analyzers at 50 kHz. A minimum of 35 subjects were included for each sex and age category from 18 to 65 years. Results: The new mean vectors showed a leftward shift on the R-Xc graph with respect to the former reference values (males: F = 75.3; p < 0.001; females: F = 36.6, p < 0.001). The results provided new 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, and 97th percentile curves for phase angle, identifying time point phases of decrement (males:-0.03 degrees per year at 33.0-51.0 years and-0.05 degrees per year after 51 years; females:-0.03 degrees per year from 37.2 to 57.9 years). Conclusions: Compared to the original references, the new data are characterized by a different distribution within the R-Xc graph with a higher phase angle. Thirty years after the BIVA invention, the current study presents new tolerance ellipses and phase angle reference values for the adult population. (c) 2023 The Authors. Published by Elsevier Ltd.

BACKGROUND:The present quasi-experimental study aimed to evaluate the effects of active breaks intervention (ABs) to promote physical and cognitive improvement in primary school.METHODS:The active breaks group (ABsG) performed 10 min of ABs three times per school day and the control group (CG) did normal lessons. The baseline and follow-up evaluation was conducted respectively in October 2019 and in May 2021. Cognitive performance was assessed using working memory test, physical performance was analyzed with ActiGraph accelerometers and physical fitness tests, quality of life was monitored using the Paediatric Quality of Life questionnaire (PedsQL) and classroom behavior was collected with an ad hoc questionnaire.RESULTS:We enrolled 153 children (age: 7.61 ± 1.41, 54.2% males). Working memory significantly increased in the ABsG (ΔWM: 1.30 ± 1.17) than in CG (ΔWM: 0.96 ± 1.20). The 6 min Cooper test increased in the ABsG (Δ: 1.77 ± 136.03) but not in CG (Δ: -156.42 ± 187.53), P < 0.05. The weekly physical activity levels increased in both groups; however, the sedentary behavior significantly increased both in ABsG and CG. Children reported improvements in their quality of school life including feeling better in class and in school when using ABs; moreover, children improved their time on task behaviors in ABsG.CONCLUSION:The present study has proven to be effective on children's physical and cognitive performance.

Purpose We compared two different strategies providing professional coaching to administer an exercise program for women with postmenopausal osteoporosis (POP): individual training (IT) at home with trainer’s supervision provided by telephone contacts at regular time-intervals or group training (GT) with trainer’s live supervision. Our working hypothesis was that IT is a valid alternative to GT when GT is not feasible. Patients and Methods This was a single-blind, randomized study. We recruited 52 women with POP, without significant comorbidity, and no participation in any structured exercise program within the previous 6 months. They were assigned randomly to IT or GT groups (n = 26 each). Distribution of age (IT: 68±4, GT: 67±8 years) and body mass index (IT: 23.0±2.5, GT: 21.4±5.1) was similar between groups. Each group performed the exercise program in two 1-hour sessions per week for 18 months. Primary outcome measure was Health-Related Quality of Life (HRQoL), as measured by the Short Osteoporosis Quality of Life Questionnaire. Secondary outcome measures focused on domains acknowledged to influence HRQoL (disability, fear of falling, weekly physical activity, physical function) or the effectiveness of the exercise program (retention, adherence, and safety). Significance level was set at p < 0.05. Results No significant differences were observed between IT and GT groups for any domain. Retention, adherence, and safety were also similar. HRQoL, disability and fear of falling did not change between baseline and follow-up for either group. However, for both groups, physical function (knee flexion, shoulder mobility) and functional capacity (6-minute walking test) improved. Weekly physical activity levels increased from moderate range at baseline to intense at final assessment for both groups. Conclusion IT and GT supervised exercise programs for women with POP provide similar effectiveness, participation and safety. Hence, both modalities should be considered for future translation in clinical practice of exercise recommendations for POP.
