This study examines the influence of muscle strength on performance metrics in volleyball, addressing the need to understand how specific and non-specific strength training impacts athletic capabilities. A cohort of athletes underwent various strength tests, including squats (SQs), bench presses (BPs), and deadlifts (DLs), to assess their force and power during various forms of test. Lactate thresholds (LT₁ and LT₂) were also measured to evaluate aerobic and anaerobic capacities. The median speed at LT₁ was 1.80 m/s, and LT₂ was determined at a mean velocity of 2.56 m/s. Notably, a correlation was found between SQ performance and total points scored (p = 0.040, r = 0.285), while upper body strength was strongly correlated with performance metrics, showing significant relationships with points scored (p = 0.0001, r = 0.690) and peak power during BPs (p = 0.0001, r = 0.587). The findings suggest that targeted strength training enhances physical capabilities and improves technical and tactical performance in volleyball, highlighting the critical role of muscle strength in athlete selection and training strategies.

(1) Background: Daily caloric intake should aim to reduce the risk of obesity or poor anthropometric development. Our study objective was to analyze the association between food consumption, inflammatory status and anthropometric development; (2) Methods: We performed a prospective observational analytical research during September 2020 and April 2021 on a group of 160 healthy subjects, aged between 6 and 12 years old, by analyzing food ingestion, the basal metabolic rate, anthropometric development and the inflammatory status; (3) Results: IL-6 was significantly correlated to the sum of skinfolds, along with both serum proteins and triglycerides. The skin folds were significantly correlated with the caloric intake and with total fat intake, next to saturated and trans fats. Unlike the skin folds, the body weight was significantly correlated with the caloric intake along with some vitamins, such as Vitamin A and Vitamin B12. Inactive mass increased with excessive folic acid, Vitamin E, Vitamin K and saturated fat intake; (4) Conclusions: The inflammatory status was influenced by the ingestion of micronutrients, total serum lipids and proteins. The anthropometric development was associated with the ingestion of carbohydrates, energy balance and energy intake. We can conclude that daily menu and nutrition imbalances can influence both the risk of obesity and the inflammatory status.

Our goal was to assess the Romanian’s food behavior according to their socio-cultural profile, in order to identify food behavior at risk and implement educational prevention methods. We performed a study based on the assessment of lifestyle and social aspects, based on an international project validated questionnaire of 26 questions, applied online in 2018 to a group of 821 adults, in Romania. The results underlined that socio-economic status was a contributing factor in food choices, people with low socio-economic status opted for low-price food, especially the elderly (40%). Regarding the preference for eating alone related to gender, both the female respondents (37.8%) and the males (50.6%) mostly disagreed, with statistical significance for males (p<0.022), also males were more influenced about what other people are eating (p<0.045). It is needed to implement new educational strategies, both in schools and adults communities, in order to reduce the risks for future chronic diseases.

(1) Background: Worldwide, public health policies focus on studying dietary patterns and the related anthropometric changes in children. Their aim is to improve the measures meant to reduce global malnutrition rates. Our goal was to study the main changes in the inflammatory status related to anthropometric changes and total daily energy intake. (2) Methods: We tested the study hypothesis by analyzing serum IL-6 and IL-8 levels, cholesterol and triglycerides values, as well as total proteins and creatinine levels, RMR, and food journals in a sample of 160 healthy subjects aged between 6 and 12 years old. (3) Results: IL-6 was correlated with the skinfold values. Changes in the skinfolds were significantly correlated with total proteins and triglycerides. Both weight for age and height for age were related to the skinfold values. Through the BMR measurements, peak carbohydrate metabolism changed significantly based upon IL-6 values, which were significantly correlated with the respiratory coefficient values. Based on the basal metabolic rate, an increased IL-8 ratio was related to the RQ value. (4) Conclusions: Skinfolds have been significantly correlated with IL-6 and IL-8 levels. With changes in body weight, we encountered differences in both serum cholesterol and serum triglycerides values, unlike total proteins and creatinine, which failed to change.

Introduction: Food allergies and intolerances represent a growing pediatric health concern. While stress-related outcomes have received increasing attention, fatigue symptoms in children with food hypersensitivity remain insufficiently characterized. The aim of the study was to evaluate perceived stress and fatigue in children with food hypersensitivity. Material and Methods: We conducted an observational cross-sectional study including 339 children aged 1–18 years with specialist-confirmed food allergy, food intolerance, or mixed pathology. Data were collected through structured parent-reported interviews incorporating the Perceived Stress Questionnaire (PSQ) and the Fatigue Assessment Scale (FAS). Results: Children with food allergy had significantly higher perceived stress and fatigue scores compared to those with food intolerance (p < 0.05), with the highest levels observed in the mixed pathology group. Both perceived stress and fatigue scores increased with age, with adolescents showing the highest values. A moderate positive correlation was identified between stress and fatigue (r = 0.49, p < 0.0001). In multivariable analyses, higher stress and fatigue scores were significantly associated with age and diagnostic category, including mixed pathology, after adjustment for sex and anthropometric indicators. Higher scores were also associated with the presence of multiple clinical symptoms, such as sleep disturbances and concentration difficulties. Conclusions: Food hypersensitivity in children is associated with a significant psychological burden characterized by elevated perceived stress and fatigue, particularly in adolescents and in those with more complex diagnostic profiles. These findings highlight the importance of multidisciplinary management strategies integrating accurate diagnosis, nutritional counseling, and psychosocial support in order to address the broader impact of pediatric food hypersensitivity.

(1) Background: With shifts in daily dietary habits, concerns have arisen regarding potential impacts on metabolic health. This study sought to investigate the interplay between nutrient intake and its effects on the anthropometric and inflammatory profiles of young individuals. (2) Methods: Our approach examined the interrelation of caloric, macronutrient, and vitamin intakes with inflammatory markers, serum cholesterol, triglycerides, and other key metrics. The impact of these factors on body mass and inflammation was evaluated. (3) Results: This study found that while increased caloric intake corresponded to a rise in body fat mass, it did not significantly alter body weight, total protein, or fat profile. A dominant carbohydrate intake negatively correlated with vitamin B consumption. Interestingly, only vitamin K showcased a direct association with IL-6, while IL-8 remained unassociated with dietary intake and body mass metrics. (4) Conclusions: Dietary intake undeniably influences nutrient consumption and subsequently affects body mass metrics. Though an escalation in body fat mass was evident with increased food intake, the relationship between vitamins and inflammatory markers, based on macronutrient and caloric intake, remains inconclusive. The findings point to the potential regulatory roles of proteins and select vitamins in inflammation, emphasizing the need for deeper longitudinal studies to further validate these connections.
