Monitoring adolescent team-sport athletes may benefit from combining performance and molecular markers, but empirical evidence supporting this approach in youth team sports remains limited. Objective: Our study investigated molecular and physiological adaptations to seasonal training in elite U18 ice hockey players, focusing on aerobic capacity, salivary cortisol, serum irisin, and cell-free DNA (cfDNA) dynamics. Methods: National-level U18 players were enrolled in our study (<i>n</i> = 23 for cross-sectional analysis, <i>n</i> = 12 longitudinal) during the pre- and early-competition season. Aerobic performance was assessed via graded treadmill VO₂max testing, and the biochemical markers quantified using ELISA-based assays. Results: From pre- to early-season (paired <i>n</i> = 12), VO₂max increased by 10.6% (g = +1.00, <i>p</i> = 0.003) and irisin by 14.7% (g = +0.83, <i>p</i> = 0.010). cfDNA decreased by 60.8% (g = −0.54, <i>p</i> = 0.070; moderate effect, not statistically clear), while cortisol remained stable (+11.3%; <i>p</i> = 0.667). Inter-individual variability increased for VO₂max and irisin and decreased by 82% for cfDNA. Exploratory cross-sectional positional analysis indicated higher irisin levels in forwards and elevated cfDNA in defensemen, although differences did not reach statistical significance. Conclusions: These preliminary findings provide cohort-size limited longitudinal evidence of chronic irisin elevation in ice hockey players and highlight the possibility of combining VO₂max + irisin + cfDNA to assist individualized load/recovery in elite youth ice hockey.

As pesquisas relacionadas ao bem-estar de comunidades turísticas estão cada vez mais em evidência, embora investigações aprofundadas que tratem dos sentimentos de residentes acerca da operação de alojamentos turísticos locais de curto prazo precisem de maiores exames. Sob a ótica da Lógica Dominante do Serviço, este artigo tem como foco explorar a influência deste modelo de negócio no bem-estar da comunidade de Braga, cidade turística ao norte de Portugal, a partir da compreensão dos sentimentos de 27 residentes entrevistados em profundidade, relacionados aos fatores de cocriação de valor e codestruição de valor percebidos. Os resultados apontam para a elevação do bem-estar da comunidade quando o negócio permite, principalmente, maior movimento econômico para a cidade. No entanto, os impactos negativos encontrados acendem um alerta sobre o futuro do negócio em Braga, uma vez que se repetem em cidades que já impuseram fortes restrições ao modelo de negócio. Pesquisas futuras podem se aprofundar em comunidades com grau de desenvolvimento turístico semelhante ou diverso, para auxiliar agentes locais na manutenção ou recuperação do bem-estar de suas comunidades.

The study aims to compare static and dynamic postural stability, navicular drop, dorsiflexion range of motion, and jumping performance of individuals with neutral, prone, and hyperprone foot postures. Forty-eight participants between the ages of 18 and 40, were categorized into neutral (n=16), prone (n=16), and hyperprone (n=16) according to foot posture index (FPI). Static and dynamic postural control evaluations (with the Biodex Balance System SD), navicular drop test (NDT) weight-bearing lunge test, countermovement jump test without arm swing, and drop vertical jump tests have been completed. In the results, the average age of participants in the NG, PG, and HPG are 22.31 ± 2.75, 23.87± 3.72, and 22.37 ± 1.28 years and BMI are 22.6 ± 3, 23.4 ± 3.8, and 21.4 ± 2.24 (kg/m²), respectively. The demographic data of the participants showed a homogeneous distribution. There were no significant differences in none of the outcomes except the NDT. Navicular drop amount is positively correlated by the subtalar joint pronation. An increase in subtalar joint pronation does not have a significant effect on static and dynamic stability, jump performance, or dorsiflexion range of motion in healthy individuals.

Introduction: Polyphenolic compounds are widespread in nature, contained in large quantities especially in fruits, vegetables, cereals and nuts. In recent years numerous attempts have been made to characterize their biological effects, with particular emphasis on their protective potential against the development of chronic diseases, including cancer. Purpose of the study: The aim of the study was to collect and analyze publications on the use of polyphenols in the prevention and treatment of cancer, with particular emphasis on breast cancer, colon cancer, prostate cancer and lung cancer - the four most common cancers in the Polish population. Material and methods: A review of the literature available on PubMed was performed using various combinations of keywords: 'polyphenols' + 'cancer', 'polyphenols' + 'oncology', ‘polyphenols’ + ‘chemoprevention’, ‘polyphenols’ + ‘chemotherapy’, 'polyphenols' + 'lung cancer', 'polyphenols' + 'breast cancer', ‘polyphenols’ + ‘colorectal cancer’, 'polyphenols' + 'prostate cancer'/'prostate gland cancer'. Results: The analysis of the collected publications allows to conclude that polyphenols exert multidirectional anticancer effect through antioxidant, antiproliferative, anti-inflammatory, immunomodulatory and prosenescence activity. This effect has been demonstrated, among others, in relation to cellular models of colorectal cancer, prostate cancer, breast cancer, cervical cancer and lung cancer. Polyphenols also reduce side effects associated with the use of conventional anticancer therapies and increase their effectiveness. Conclusions: Polyphenols - both as independent compounds and components of complex anticancer treatment regimens - have chemopreventive and potentially chemotherapeutic effects. By influencing various stages of carcinogenesis - initiation, promotion and progression of cancer - they constitute a promising direction for the development of new, more effective forms of therapy and prevention of cancer.

COVID-19 süreci dünya genelinde birçok sağlık sorununa neden olduğu gibi, kısıtlamalar, hareketsiz bir yaşantı ve sağlıksız beslenme alışkanlıklarını beraberinde getirdi. Normalleşme süreçlerinde özellikle ergen bireylerde fiziksel aktivite ve beslenme davranışlarındaki değişimlerin takip edilmesi, toplum sağlığının izlenmesi açısından önemli görülmektedir. Adölesan dönem bireylerin çocukluktan yetişkinliğe geçiş yaptıkları, hem fiziksel hem de psikososyal anlamda hızlı değişimlerin yaşandığı kritik bir dönemdir. Bu yaş grubunda sağlıklı yaşam alışkanlıklarının teşvik edilmesi, uzun vadeli sağlık açısından büyük öneme sahiptir. Bu araştırmanın amacı COVID-19 sonrası süreç de lise öğrencilerinde fiziksel aktivite, beslenme davranışı ve VKİ düzeyleri ile bunlar arasındaki ilişkilerin incelenmesidir. Araştırmaya, Uşak ilindeki genel ortaöğretim okullarında öğrenim gören 278 kız (14±3,4 yaş), 192 erkek (14±3,1 yaş), olmak üzere toplamda 470 öğrenci gönüllü olarak katılmıştır. Çalışmada veri toplama araçları olarak “Kişisel Bilgiler Formu” fiziksel aktivite durumlarını belirlemek için “Fiziksel Aktivite Soru Formu” beslenme davranışlarını için ise “Beslenme Davranış Ölçeği” kullanılmıştır. Araştırmaya katılım sağlayan öğrencilerin vücut kitle indekslerini tespit etmek için Dünya Sağlık Örgütü (WHO) tarafından kabul edilen kg/m2 formülü kullanılmıştır. Araştırmada elde edilen veriler SPSSIBM 26 paket program kullanılarak analiz edilmiştir. Verilerin analizinde betimsel istatistik, bağımsız örneklem t-testi, Pearson korelasyon analiz analiz teknikleri kullanılmıştır. Sonuç olarak katılımcıların fiziksel aktivite düzeyleri (X̄= 25,37±5,759) oldukça düşük, beslenme davranış puanları (X̄= -2,04±5,221) çok kötü, Vücut Kitle İndeks puanları ise (X̄= 21,2343±2,76047) normal sınırlarda tespit edilmiştir. VKİ puanlarında kızlarda erkeklere göre daha düşük VKİ sergilerken fiziksel aktivite düzeyleri ve beslenme davranış puanları farklılaşmamaktadır. Katılımcıların VKİ sınıflamalarına göre fiziksel aktivite ve beslenme davranış puanları arasında pozitif bir ilişki tespit edilmilştir.

Cardiovascular disease is the leading cause of human death worldwide. Autophagy is an evolutionarily conserved degradation pathway, which is a highly conserved cellular degradation process in which lysosomes decompose their own organelles and recycle the resulting macromolecules. Autophagy is critical in maintaining cardiovascular homeostasis and function, and excessive or insufficient autophagy or autophagic flux can lead to cardiovascular disease. Enormous evidence indicates that exercise training plays a beneficial role in the prevention and treatment of cardiovascular diseases. The regulation of autophagy during exercise is a bidirectional process. For cardiovascular disease caused by either insufficient or excessive autophagy, exercise training restores normal autophagy function and delays the progression of cardiovascular disease. An in-depth exploration and discussion of exercise-mediated regulation of autophagy in the cardiovascular system can broaden our view about the prevention of various autophagy-related diseases through exercise training. In this article, we review autophagy and its related signaling pathways, as well as autophagy-dependent beneficial effects of exercise in cardiovascular system.

Background: Over 300 million people around the world have thyroid problems. Hashimoto’s thyroiditis is the most common reason for hypothyroidism among people aged 45 to 65, mostly women. Hashimoto’s thyroiditis is a mysterious immune-mediated disease and its reason is still not fully clear. According to specialists nutritional habits have impact on the development of the disease. Fatigue, reduction of exercise capacity, movement deceleration, drowsiness, hair and eyebrow loss, dry skin, nail fragility, feeling cold and chronic constipation are dominant feelings in the clinical picture of the disease. The objective of the paper is indication of food ingredients that support thyroid gland activity as well as those that should be limited. Content: In many publications it is emphasized that right nutrition and proper selection of nutrients are necessary in occurring and development of Hashimoto’s thyroiditis. The diet of patients with hypothyroidism should be based on increased content of complete protein, polyunsaturated fatty acids as well as carbohydrates with a low glycaemic index. Consumption of complex carbohydrates which provide the most of mineral nutrients, vitamins and dietary fibres is recommended. The supply of vitamins and mineral nutrients is important due to their impact on secretory activity of the thyroid. They include iodine, iron, selenium and zinc as well as vitamins: A, D, E, B2, B3 and B12. Existence of relation between vitamin D deficiency and the risk of development of autoimmune thyroiditis is also indicated. Summary: The diet of patients with Hashimoto’s thyroiditis should be considered in a complex way, including hormone deficiency as well as changes in diet and supplementing it in necessary mineral nutrients and vitamins. Therefore education regarding the rules of proper nutrition should be a component of the process of treatment.

It was observed previously that New Zealand blackcurrant (NZBC) extract reduced slowing of the maximal 15 m sprint speed during the Loughborough Intermittent Shuttle Test. We examined the effect of NZBC extract on the performance of the Running Based Anaerobic Sprint Test (RAST, 6 × 35-m sprints with 10 seconds passive recovery) in trained youth and recreationally active football players. Fifteen recreationally active (University team) (age: 20 ± 1 years, height: 174 ± 19 cm, body mass: 80 ± 13 kg) and nine trained youth players (English professional club) (age: 17 ± 0 years, height: 178 ± 8 cm, body mass: 69 ± 9 kg, mean ± SD) participated in three testing sessions. Prior to the RASTs, participants consumed two capsules of NZBC extract (600 mg∙day−1 CurraNZ®) or placebo (P) for 7 days (double blind, randomised, cross-over design, wash-out at least 14 days). Ability difference between groups was shown by sprint 1 time. In the placebo condition, trained youth players had faster times for sprint 1 (5.00 ± 0.05 s) than recreationally active players (5.42 ± 0.08 s) (p &lt; 0.01). In trained youth players, there was a trend for an effect of NZBC extract (p = 0.10) on the slowing of the sprint 1 time. NZBC extract reduced slowing of the sprint 5 time (P: 0.56 ± 0.22 s; NZBC: 0.35 ± 0.25, p = 0.02) and this was not observed in recreationally active players (P: 0.57 ± 0.48 s; NZBC: 0.56 ± 0.33, p = 0.90). For fatigue index, expressed as a % change in fastest sprint time, there was a strong trend to be lower in both trained youth and recreationally active players combined by NZBC extract (P: −13 ± 7%; NZBC: −11 ± 6%, p = 0.06) with 12 participants (five trained youth) experiencing less fatigue. New Zealand blackcurrant extract seems to benefit repeated sprint performance only in trained football players.
