The purpose of this study was to examine vegetable consumption and its relationship with lifestyle characteristics among children and adolescents. Data from a health survey administered to a representative sample of 177,091 schoolchildren between the ages of 8 and 17 were employed in this observational, cross-sectional investigation. Physical activity level, screen time, and sleeping patterns were assessed using self-completed questionnaires. Vegetable consumption and dietary habits were analyzed using the Mediterranean Diet Quality Index for Children and Adolescents. Participants consuming vegetables more than once daily were categorized as consumers vs. non-consumers. Physical education teachers measured anthropometric and physical fitness factors. Descriptive statistics and binary logistic regression analysis were conducted, and the odds ratio with the corresponding 95% confidence interval was calculated and adjusted for confounders. Vegetables were consumed once or more times a day by more females than males (25.5% vs. 24.0%, p < 0.001). In both sexes, vegetable consumers slept more, ate healthier, spent less time on screens, and had better anthropometric and aerobic fitness measurements than non-consumers. Healthy eating practices, such as regularly consuming fruits, legumes, nuts, and dairy products, were strongly correlated with vegetable intake. For every one-year increase in age, the odds of being a vegetable consumer decreased by 8% and 10% in boys and girls, respectively. Overweight/obese participants had lower odds of being a vegetable consumer by 20%. Increased screen time, inadequate physical activity, and insufficient sleeping hours decreased the odds of being a vegetable consumer by 22%, 30%, and 25%, respectively (all p-values < 0.001). Overall, a healthier lifestyle profile was associated with higher vegetable intake for both sexes among children and adolescents. Full article

Background: Chronic stress in childhood and adolescence leads to excessive cortisol secretion, adipokines production and obesity with all the negative mental and physical effects on the health of individuals and adulthood. Objectives: The aim of the present non-randomized controlled trial was to investigate the effect of a stress management protocol with diaphragmatic breathing (DB) and physiotherapy exercise on stress, body composition, cardiorespiratory and metabolic markers of children and adolescents with morbid obesity. Methods: The study included 31 children and adolescents (5–18 years old) with morbid obesity (22 in the intervention arm and 9 controls). All participants completed anxiety questionnaires and a self-perception scale. Forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), blood pressure (BP) and SpO₂ were measured. Fasting glucose, uric acid, triglycerides, HbA1c, (AST/SGOT), (ALT/SGPT), HDL, LDL, insulin, ACTH, cortisol, HOMA-IR, 17-OH, S-DHEA, SHBG were assessed, and anthropometric measurements were also performed. Results: In the intervention group, 4 months after the treatment, an improvement was noted in the BMI, BMI z-score, waist-to-height ratio, FEV1, SpO₂, pulse and systolic BP. HDL increased, ALT/SGPT and insulin resistance improved. Positive changes were observed in temporary and permanent stress and self-esteem of children in the intervention group, including anxiety, self-perception, physical appearance, etc. Conclusions: A combined exercise and DB protocol has a positive effect on stress, by improving body composition, reducing insulin resistance, and ameliorating physical and mental health and quality of life of pediatric patients with morbid obesity.

Mild cognitive impairment (MCI) is the transitional stage between normal cognition and dementia and is associated with arterial stiffness, which may lead to cardiovascular disease. A water-based exercise (W) presents a low-impact activity for the joints and increases resistance compared to exercises performed in the air, which benefits older adults. However, little evidence has been found regarding the effect of W on promoting cognitive and physical performance in older individuals with MCI. Therefore, this study aimed to investigate and compare the post-training effects of W alone and in combination with cognitive training on cognitive function, cardiovascular fitness, and arterial stiffness in older adults with MCI. Forty-six adults with MCI, aged 65 years or older, were enrolled. Participants were divided into two groups: a W group and a water-based exercise combined with cognitive training (W-COG) group. Both groups performed an aerobic exercise program in water for 60 min per/day, 3 day/week, for 12 weeks. Participants in the W-COG group simultaneously performed aerobic exercise and cognitive training in water. Cognitive performance, cardiovascular fitness, and arterial stiffness were examined before and after the intervention. The results revealed improvements in cognitive performance and cardiovascular fitness in both the W and W-COG groups after 12 weeks of intervention. However, there were no significant differences in cognitive and cardiovascular fitness changes between the two groups. Neither the W nor the W-COG groups showed a decrease in brachial pulse wave velocity. Therefore, W interventions have the potential to enhance cognitive function, restore cognition, and improve cardiovascular fitness in older adults with MCI. Full article

Background: Well-designed endurance training leads to improved cardiovascular fitness and sports performance in prolonged exercise tasks, with the adaptations depending on multiple factors, including the training modality and the population in question. It is still disputable how the type of training affects myocardial remodeling, and the information on myocardial remodeling by high-intensity interval training (HIIT) is particularly scarce. Methods: The current study investigated changes in cardiac structure after volume-progressive HIIT in running mode. As part of their conditioning program, amateur athletes (mean ± SD age of 18.2 ± 1.0 years) exclusively conducted HIIT in a volume-progressive fashion over 7 weeks (a total of 21 sessions). Peak oxygen uptake as well as 200 m and 2000 m running performance were measured, and transthoracic two-dimensional echocardiography was conducted before and after the intervention. Results: Training improved running performance, increased the peak oxygen uptake and left atrium diameter (from 32.0 ± 2.5 to 33.5 ± 2.3 mm; p = 0.01), and induced ~11% thickening of the left-ventricular posterior wall (7.5 ± 0.7 to 8.2 ± 0.4 mm; p = 0.01) and interventricular septum (7.6 ± 0.7 to 8.6 ± 0.9 mm; p = 0.02), but not the dilation of left-ventricular, right-ventricular, or right atrium chambers. Conclusions: HIIT of just 127 km of running per 8.5 h during 7 weeks was sufficient to improve aerobic capacity and running performance, and induce left-ventricular wall hypertrophy and left atrium dilation, in young healthy athletes.

There have been some studies investigating the effects of air pollutants on male football players, but few have examined the gender-specific impact of air pollution on the athletic performance of female football players. This research gap limits the development of tailored training and competition strategies. Here, generalized mixed modeling was employed to assess the effects of main ambient air pollutants, i.e., particulate matter less than 2.5 μm (PM_2.5), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon monoxide (CO), on athletic performance indicators (total movement distance (TMD), jogging distance (JD), and walking distance (WD)) among 14 female football players during 16 matches in the 2020 season of the Chinese Football Association Women’s Super League. Our findings indicate a significant negative association between the O₃ concentration and athletic performance, with fixed effect coefficients of −22.426 ± 8.889 for TMD, −10.817 ± 3.697 for JD, and −6.943 ± 3.265 for WD. The NO₂ concentration was significantly correlated with both TMD and JD, while PM_2.5, SO₂, and CO concentrations had minimal or negligible effects. Additionally, aerobic fitness was reduced as the O₃ concentration increased. These results provide valuable insights for optimizing gender-specific training and competition strategies under varying air quality conditions, offering a basis for more targeted health and performance interventions in professional female football players.

Cardiac rehabilitation should be suggested after mitral valve intervention. Physical exercise is associated with improved cardiorespiratory fitness and clinical outcome and reduced rehospitalization and mortality in patients after heart valve surgery. Tailored assessment is the first step before starting a cardiac rehabilitation program. Physical examination, electrocardiogram, echocardiography, and peak exercise capacity stratify the risk of these patients when prescribing appropriate supervised aerobic and resistance exercise training. Cardiac rehabilitation participation impacts physical capacity, psychosocial function, and prognosis in patients after mitral valve surgery and transcatheter edge-to-edge repair. However, further evidence is needed on the efficacy and safety of cardiac rehabilitation programs, as well as standardization. In this review, we provide a contemporary and comprehensive update on the role of cardiac rehabilitation in patients after mitral valve intervention, after both mitral valve surgery and transcatheter mitral valve implantation. Specifically, we focus our review on the tailored assessment and management of these patients from post-operative to cardiac rehabilitation. Full article

Sedentary behavior among young women is increasingly associated with adverse metabolic and cardiovascular outcomes. The aim of this randomized controlled trial was to evaluate and compare the effects of three structured group fitness programs on anthropometric parameters, body composition, and lipid profile in overweight young women (N = 111, age 18–25, BMI ≥ 25). Participants were assigned to mix aerobics (E1, n = 27), kickbox aerobics (E2, n = 28), step aerobics (E3, n = 27), or a control group (C, n = 29). Each intervention lasted 12 weeks, with sessions conducted three times per week, each lasting 60 min. The results were analyzed using repeated measures ANOVA. Significant reductions were observed in body weight (−4.8 kg in E1, p < 0.01), waist circumference (−5.3 cm in E1, p < 0.001), and body fat percentage (−3.6% in E1, p < 0.01). High-density lipoprotein (HDL) increased by 7.4 mg/dL (p < 0.01), while low-density lipoprotein (LDL), total cholesterol, and triglycerides decreased by 12.1 mg/dL, 18.6 mg/dL, and 19.4 mg/dL, respectively (all p < 0.01). The most pronounced overall improvements were found in the mix aerobics group. In contrast, the control group showed significant deterioration in most variables, including a 2.1 kg weight gain and a 6.3 mg/dL increase in total cholesterol (p < 0.05). These findings confirm the superior effectiveness of mix aerobics as a non-pharmacological intervention to improve body composition (notably through reductions in body weight, fat percentage, and waist circumference) and cardiovascular biomarkers (such as increased HDL and decreased LDL, total cholesterol, and triglycerides) in young overweight women. Compared to kickboxing and step aerobics, mix aerobics consistently achieved the greatest improvements across all measured parameters, making it the most comprehensive and effective option among the three programs tested.

Background/Objectives: High-intensity interval training (HIIT) can optimize recovery by complementing the low cardiovascular fitness intensities typically achieved in stroke rehabilitation programs. Skating exercise is an HIIT workout developed based on ice skating movements, and we investigated the effects of this exercise on the cardiorespiratory fitness of elderly patients with minor stroke. Methods: Participants aged 65 or older with a National Institutes of Health Stroke Scale score of 3 or lower were recruited. This study was designed as a randomized controlled trial, in which the intervention group engaged in skating exercises following HIIT, while the control group underwent moderate-intensity continuous training (MICT). Both groups of participants performed either HIIT or MICT for 20 min per day, four times a week, over three months. Results: A total of 34 elderly patients with minor stroke were recruited, with an average age of 70.7 years. For three months, no fall-down injuries or adverse cardiovascular or cerebrovascular events were reported among patients undergoing HIIT or MICT. Both the intervention and control groups showed significant increases in the measures of aerobic capacity after the intervention. However, the patients in the intervention group exhibited significantly greater improvements in peak oxygen uptake, ventilatory threshold, and peak MET (p = 0.005, p = 0.002, and p = 0.024, respectively). Additionally, the Berg Balance Scale (BBS) scores and the skeletal muscle mass index showed significantly greater enhancements in the intervention group compared to the control group (p = 0.032 and p = 0.032). Conclusions: In conclusion, skating exercise could be a safe and effective HIIT protocol for elderly people who have experienced a minor stroke. Full article

Background/Objectives: Long-distance runners with exercise-induced hypertension (EIH) are at increased risk for cardiovascular complications. Although blood flow restriction (BFR) training has shown promise in improving vascular function, hemodynamic response, and cardiorespiratory fitness, its effects in EIH runners remain understudied. This study aimed to evaluate the effects of BFR training on cardiovascular responses and exercise performance in this population as a potential non-pharmacological therapy. Methods: Middle-aged male long-distance runners aged 40–65 with peak systolic blood pressure (SBP) ≥ 210 mmHg during graded exercise testing were randomly assigned to either a BFR group (n = 18) or a non-BFR control group (n = 15) using a computer-generated random sequence. There were no significant differences in baseline characteristics between the groups. Both groups performed aerobic training at 40–60% HRR for 20 min twice weekly for 8 weeks. SBP, diastolic blood pressure (DBP), rate pressure product (RPP), ventilatory threshold (VT), VO_₂max, and perceived exertion were assessed before and after the intervention at rest, during exercise, and during recovery. Results: Compared to the non-BFR group, the BFR group showed statistically significant reductions in resting and maximal SBP and DBP (p < 0.05), along with significant increases in VO_₂max and VT (p < 0.05). During submaximal exercise and post-exercise recovery, SBP and RPP were significantly lower in the BFR group (p < 0.05). The reductions in maximal SBP and DBP were significantly greater in the BFR group than in the control group. Conclusions: BFR training led to reduced myocardial workload and enhanced cardiovascular efficiency in male runners with EIH. These findings suggest that BFR training may be a viable non-pharmacological therapy for mitigating cardiovascular risks associated with EIH. Future studies should explore the long-term effects of BFR in broader populations and assess its applicability in clinical settings. Full article

Background: Cystic fibrosis (CF) is a chronic genetic disease marked by progressive lung function decline and increased respiratory infections. Emerging evidence supports the role of physical exercise in improving lung function, aerobic capacity, and quality of life in pediatric CF patients. Methods: We reviewed randomized clinical trials and observational studies from the last ten years, sourced from PubMed and Google Scholar. Included studies involved children and adolescents (0–18 years) with CF and assessed physical exercise as a primary intervention to improve lung function, aerobic fitness, quality of life, or hospitalization rates. Results: Aerobic training, particularly when combined with strength training, improves cardiorespiratory fitness and muscle strength without compromising nutritional status. High-Intensity Interval Training and Inspiratory Muscle Training show potential but need further validation. Supervised, personalized exercise programs are key to promoting adherence and optimizing outcomes. Conclusions: Exercise-based interventions in pediatric CF should evolve toward personalized, technology-enhanced, and sustainable models. Integrating wearable devices, adapting programs to individual needs, and leveraging early parental involvement may enhance engagement and outcomes, especially in the era of CFTR modulator therapies.

This study evaluated the differential effects of an advanced Vivifrail D-level exercise intervention on arterial stiffness, functional fitness, and body composition in robust older women with varying baseline fitness levels. A total of 41 participants were assigned to a higher-fitness group (HFG, n = 22) or a lower-fitness group (LFG, n = 19) based on their 30 s chair stand performance. Over 12 weeks, both groups completed five weekly sessions incorporating strength, balance, aerobic, and dual-task elements. Significant within-group improvements were observed in the arm curl test (HFG: p = 0.031; LFG: p = 0.002), chair stand (LFG: p < 0.001), and 2 min step test (LFG: p = 0.002). Between-group analysis showed greater percentage gains in the LFG for the chair stand (33.8% ± 28.2% vs. 7.1% ± 21.6%, p = 0.001) and step test (13.7% ± 14.5% vs. 5.3% ± 14.7%, p = 0.040). No significant changes were found in handgrip strength, gait speed, pulse wave velocity, or muscle mass. These results suggest that the modified Vivifrail protocol enhances lower-limb endurance in lower-fitness individuals, but additional adaptations may be necessary to impact vascular and compositional outcomes.

Background: Sarcopenia is characterized by low muscle mass and strength, as well as impaired physical performance. Older adults with sarcopenia experience decreased cardiorespiratory fitness. Physical exercise is recommended for the prevention and treatment of sarcopenia. Virtual reality (VR) exercise was introduced to improve physical activity. However, the effect of VR on cardiorespiratory function in older adults with sarcopenia has not been fully explored. This study aimed to explore the effects of home-based VR aerobic exercise combined with resistive exercise on cardiorespiratory performance in community-dwelling older adults with sarcopenia. Subjects and Methods: In a randomized controlled trial, 53 older adults with sarcopenia were divided into a home-based VR (n = 26) and a control group (CG; n = 27). The VR program combined aerobic and resistance exercises, performed three times per week for 12 weeks, while the CG received knowledge regarding the benefit of exercise and continued with their regular daily activities. All participants were required to undergo respiratory muscle strength and functional capacity tests before and after the 12-week intervention. Two-way mixed repeated ANOVA was conducted to compare within and between groups in cardiorespiratory performance. Results: The home-based VR exercise group showed significant improvement in pre-post (i.e., maximal inspiratory pressure (12.96 ± 1.49 cmH₂O), maximal expiratory pressure (13.73 ± 1.72 cmH₂O), functional capacity (28.32 ± 3.48 m), and between-group (maximal expiratory pressure (F (1,51) = 10.446, p = 0.002, np² = 0.170). In contrast, the CG displayed a reduction in maximal expiratory pressure (−3.93 ± 1.69 cmH₂O, p = 0.024) and functional capacity (−10.39 ± 3.42 m, p = 0.004) after the 12-week program. Conclusions: The home-based VR program provides older adults with sarcopenia an alternative exercise modality that can improve their cardiovascular performance. Full article

Australia’s aging migrant population experiences higher rates of chronic disease and social isolation, highlighting the need for culturally appropriate health promotion programs. This study evaluated the effectiveness of “Move Together”, a culturally adapted community-based group exercise and education intervention for Mandarin-speaking Chinese Australians aged 65+ years. The Model for Adaptation, Design, and Impact framework guided the adaptation of this program. This single-arm pre–post-intervention was delivered bilingually by accredited exercise physiologists over nine weeks to 101 adults (mean age: 72.3 ± 5.3 years; 38% male). The physical health assessments measured waist circumference, aerobic capacity, strength, flexibility, and balance, while the questionnaires evaluated quality of life and social connectedness. The results showed significant improvements in all physical health measures (p < 0.001), with more participants meeting fitness standards for healthy independent living. Participants also reported significant improvements in self-perceived quality of life and social connectedness. The Move Together program effectively improved physical health and psychosocial well-being among older Chinese Australians through its culturally adapted, bilingual delivery model. These findings provide valuable insights for health professionals and policymakers adapting and implementing programs for culturally and linguistically diverse older populations to address chronic disease risks and social isolation.

Background: Prehabilitation is increasingly being used in patients undergoing multimodality treatment for oesophagogastric cancer (OGC). Most studies to date have been small, single-centre trials. This collaborative study sought to assess the overall impact of prehabilitation on patient outcomes following OGC surgery. Methods: Data came from four prospective prehabilitation trials conducted in the UK or Ireland in patients undergoing multimodality treatment for OGC. The studies included three randomised and one non-randomised clinical trial, each comparing a prehabilitation intervention group to controls. The prehabilitation interventions included aerobic training delivered by exercise physiologists alongside dietetic input throughout the treatment pathway. The primary outcome was survival (all-cause and disease-specific mortality). Secondary outcomes were differences in complications, cardio-respiratory fitness (changes in VO_{2 peak} and anaerobic threshold (AT)), chemotherapy completion rates, hospital length of stay, changes in body mass index, tumour regression and complication rates of anastomotic leak and pneumonia. Cox and logistic regression analysis provided hazard ratios (HR) and odds ratios (OR), respectively, with 95% confidence intervals (CI), adjusted for confounders. Results: Among 165 patients included, 88 patients were in the prehabilitation group and 77 patients were in the control group. All-cause and disease-specific mortality were not improved by prehabilitation (HR 0.67 95% CI 0.21–2.12 and HR 0.82 95% CI 0.42–1.57, respectively). The prehabilitation group experienced fewer major complications (20% vs. 36%, p = 0.034; adjusted OR of 0.54; 95%CI 0.26–1.13). There was a mitigated decline in VO_2 peak following neo-adjuvant therapy (delta prehabilitation −1.07 mL/kg/min vs. control −2.74 mL/kg/min; p = 0.035) and chemotherapy completion rates were significantly higher following prehabilitation (90% vs. 73%; p = 0.016). Hospital length of stay (10 vs. 12 days, p = 0.402) and neoadjuvant chemotherapy response (Mandard 1–3 41% vs. 35%; p = 0.494) favoured prehabilitation, albeit not statistically significantly. Conclusion: Despite some limitations in terms of heterogeneity of study methodology, this study suggests a number of meaningful clinical benefits from prehabilitation before surgery for OGC patients. Current initiatives to agree on national standards for delivering prehabilitation and the results of ongoing trials will help to further refine this important intervention and expand the evidence base to support the widespread adoption and implementation of prehabilitation programs.

Objectives: This explorative study aimed to evaluate athletes’ perceptions of how CrossFit^® affects physical, psychological, and social well-being, exploring gender differences. CrossFit^® is a high-intensity functional training modality aimed at enhancing overall fitness and health. Limited research has explored its perceived impact on broader aspects of well-being, particularly considering gender differences. Methods: A total of 202 participants (age 34.3 ± 10.0 years) with at least 6 months of CrossFit^® experience completed an online self-reported questionnaire not previously published but created following published guidelines. The questions explore athletes’ perceptions of their improvements in physical fitness, injury occurrence, and the effects on mental well-being. Statistical analysis included descriptive statistics and parametric and non-parametric tests to investigate gender differences. Results: In total, 81.2% of participants perceived improvements in strength, while 83.2% reported enhanced aerobic capacity. Significant body composition improvements were noted by 68.3% of the sample, and 87.6% reported changes in eating habits. Injury incidence was lower among women (30.2%) than men (45.3%) (p = 0.02). Regarding psychological outcomes, 95% of respondents indicated a reduction in stress levels, 73.3% reported better sleep quality, and over 90% perceived improvements in self-esteem and daily energy. Furthermore, 98.5% of participants formed new social connections through CrossFit^®, with 79.2% acknowledging a positive impact on social relationships. No significant gender differences were found across most psychological and social outcomes. Conclusions: CrossFit^® is perceived positively by participants, with similar views across genders, except for injury rates. It enhances physical fitness, mental health, and social well-being, with high training adherence and relatively low injury risk. Full article
