Background: Social support has been identified as a key factor influencing adolescents' engagement in physical activities. However, the relationship between middle school girls' physical activity levels and the actual social support they receive remains unclear.
Aim: This study aims to explore the support mechanisms that promote increased physical activity participation among middle school girls.
Methods: A survey was conducted with 1,371 middle school girls from 16 regions and cities in China. The questionnaire included the Physical Activity Questionnaire (PAQ), the Social Support and Exercise Survey, the Physical Activity Rank Scale, and the Family Affluence Scale (FAS). Linear regression was used to examine the relationships among family support, out-of-school exercise behavior, in-school exercise behavior, and the physical activity levels of middle school girls.
Results: In-school physical activity participation (6.6%) was higher than out-of-school participation (5.5%) among urban middle school girls. Physical activity levels were significantly positively correlated with social support from family, peers, and teachers ( < 0.01). Linear regression and descriptive statistics consistently showed that family support was the highest (3.50 ± 1.06), followed by teacher support (3.17 ± 0.96) and peer support (2.88 ± 0.96). Emotional support was notably higher, while instrumental support was relatively low. The physical activity levels of urban middle school girls were associated with the age and grade of the individual, the economic conditions of the family, and the highest level of education of the parents.
Conclusion: Family support significantly enhances urban middle school girls' participation in physical activities. Higher parental education levels may reduce girls' activity participation, while improved family economic conditions may decrease emotional support but increase informational support. The support of friends and teachers will make up for the decrease in family support. A school-based social support network is essential to address disparities in activity support and implement health intervention programs for middle school girls.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.

Importance: Excess body fat plays a pivotal role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). HU6 is a novel, controlled metabolic accelerator that enhances mitochondrial uncoupling resulting in increased metabolism and fat-specific weight loss.
Objective: To assess efficacy and safety of HU6 in reducing body weight, improving peak volume of oxygen consumption (VO2) and body composition among patients with obesity-related HFpEF.

Purpose Of The Review: This review summarises high-level evidence for fan therapy and adds a commentary on the relatively-neglected question of how to optimise benefits based on qualitative evidence, clinical experience and broader research and theory.
Recent Findings: Recent high-level evidence suggests the fan reduces time to recovery from episodic breathlessness rather than reduces daily levels over a longer period. Lower grade evidence suggests the fan can also help people increase their physical activity.
Importance: Exercise intervention studies have shown benefits for patients with lung cancer undergoing surgery, yet most interventions to date have been resource intensive and have followed a one-size-fits-all approach.
Objective: To determine whether a personalized, clinic-aligned perioperative exercise program with remote monitoring and instructions can improve physical function and fatigue among patients undergoing surgery for lung cancer.
Design, Setting, And Participants: The Precision-Exercise-Prescription (PEP) randomized clinical trial is a single-center phase 3 trial.

Importance: Sexual dysfunction is a common adverse effect of prostate cancer treatment, and current management strategies do not adequately address physical and psychological causes. Exercise is a potential therapy in the management of sexual dysfunction.
Objective: To investigate the effects of supervised, clinic-based, resistance and aerobic exercise with and without a brief psychosexual education and self-management intervention (PESM) on sexual function in men with prostate cancer compared with usual care.
