Lifelong football training influences miR-1303 serum expression and human breast cancer MCF-7 cells motility: A pilot study
Introduction MicroRNAs (miRNAs) are key components in the interaction between lifestyle-related risk factors and cancer development. In particular, miR-1303 expression is deregulated in breast cancer tissues, with elevated levels associated with poor prognosis. We have previously shown that regular exercise reduces the expression of this miRNA in skeletal muscle. The present pilot study aimed to evaluate the impact of lifelong football training o…
Beyond the game: Evaluating a soccer-centered approach to physical activity and health education in children
Background/objectives Due to only 25% of U.S. children meeting the physical activity guidelines, we aimed to determine feasibility of team sports to engage children in at least 60 min of moderate-to-vigorous physical activity daily and increase health knowledge. Methods This 11-week quasi-experimental pre/post intervention study was conducted in two after-school programs around metro Atlanta, GA, USA (C1, n = 18; C2, n = 22). The 11 for Health pr…
Effects of Recreational Soccer and Team Handball Training on Cognitive and Physical Performance in Male Adolescents
Recreational soccer (RS) and recreational team handball (RTH) have gained recognition for its positive effects on health indices among untrained participants. We aimed to evaluate and compare the effects of regular RS and RTH on selective attention and physical fitness among untrained adolescents. Participants were randomly assigned to participate in a 3-month RS or RTH training program [2 sessions/week, RS group ( n = 10; Age: 17.11 ± 0.60 years…
Maintaining conceptual fidelity through teacher-led adaptation: An implementation-focused mixed methods study of a school-based physical activity program
School-based physical activity programs are widely promoted to address adolescent physical inactivity, yet their population-level impact is often limited by implementation challenges in real-world school settings. While implementation fidelity is frequently assessed, less is known about how teachers actively balance adherence and local adaptation while maintaining core program principles. This study examined the implementation of the FIT FIRST Te…
Walking handball as an exercise alternative to conventional walking and recreational team handball
WH elicits moderate-intensity internal load, comparable to conventional walking modalities, with lower total distance covered, but higher frequency and magnitude of accelerations and decelerations, while showing lower RPE, and higher fun scores. This supports its potential to enhance cardiovascular and musculoskeletal health, while fostering long-term exercise adherence. RTH provides the strongest overall training stimulus for fitness and health …
Capturing the wider benefits from football participation: A social return on investment (SROI) evaluation of a community based football intervention
The computed SROI ratios for a single site and for ten sites compare favourably with those of other health initiatives particularly other football and community based SROI evaluations. Furthermore, this study quantifies the benefits of football participation from a mental health and social perspective in addition to physical benefits, and it also highlights the benefits of football participation to other stakeholders such as participants' family …
Football cooperative: A pragmatic controlled trial of a community-based physical activity social intervention for men when replicated using a Social Return on Investment (SROI) framework protocol pape…
Across the western world, men tend to have lower life expectancy compared to women and have higher mortality rates for most of the leading causes of deaths at all ages. While biological factors such as genetics and hormones may seem to contribute to men’s heightened vulnerability to certain diseases and health conditions, these elements alone do not fully explain the significant disparities observed in health outcomes between men and women. To ad…
Health-Related Quality of Life Findings From the Faroe Islands Fit First for All School-Based Physical Activity Study
The FIT FIRST FOR ALL program improved physical well-being, particularly among boys and younger age groups, showcasing its potential to influence selected dimensions of HRQOL through structured school-based physical activity. These findings suggest that tailoring the program to specific age and gender groups could further strengthen its scalability and effectiveness across diverse school settings
