Purpose: This systematic review and meta-analysis aimed to assess the effect of aerobic exercise on circulating vascular endothelial growth factor (VEGF) levels in adults, given the inconsistent results in randomized controlled trials (RCTs), which is the basis for our investigation.
Methods: A comprehensive search of ISI Web of Science, PubMed/MEDLINE, and Scopus was conducted up to May 2025. Thirteen RCTs satisfied eligibility criteria. We performed a random-effects meta-analysis to estimate the overall Standrad mean difference (SMD) in VEGF between aerobic exercise group and control group. We conducted subgroup analyses dated on exercise intensity, duration, and biological sample (serum versus plasma).
Results: The results of the pooled analysis demonstrated no significant overall effect of aerobic exercise on circulating VEGF levels ) SMD: - 0.075; 95% CI: - 0.246 to 0.096; p = 0.390; I2 = 32.9%; τ² = 0.030; PI = -0.5 to 0.35(. Observed reduction in VEGF levels occurred in the studies utilizing interventions with a duration of ≤ 8 weeks. Evidence certainty was rated as very low.
Conclusions: It appears that aerobic exercise does not have significant overall influence on circulating VEGF levels. However, VEGF reductions may subsequently occur after short-duration interventions. Further research is needed with larger high-quality RCTs to verify these associations and further explore the mechanisms.
目的:本系统综述和荟萃分析旨在评估有氧运动对成人循环血管内皮生长因子(VEGF)水平的影响,随机对照试验(RCTs)的结果不一致,这是我们研究的基础。方法:综合检索截至2025年5月的ISI Web of Science、PubMed/MEDLINE和Scopus。13项rct符合入选标准。我们进行了随机效应荟萃分析,以估计有氧运动组和对照组之间VEGF的总体标准平均差异(SMD)。我们对运动强度、持续时间和生物样本(血清和血浆)进行了亚组分析。结果:合并分析结果显示,有氧运动对循环血管内皮生长因子水平的总体影响不显著)SMD: - 0.075;95% CI: - 0.246 ~ 0.096;p = 0.390;i2 = 32.9%;τ²= 0.030;PI = -0.5 ~ 0.35(。在使用持续时间≤8周的干预措施的研究中观察到VEGF水平的降低。证据确定性被评为非常低。结论:有氧运动似乎对循环血管内皮生长因子水平没有显著的总体影响。然而,在短期干预后,VEGF可能会减少。进一步的研究需要更大的高质量随机对照试验来验证这些关联并进一步探索其机制。

<p><strong>Background: </strong>The aim of this randomized controlled trial was to determine the effects of a four-week running-based high-intensity interval training (HIIT) intervention on the reactive strength index (RSI) and motor abilities in youth football players. In this context, the contributions of the running-based HIIT protocol HIIT protocol, implemented in addition to regular football training, were evaluated on performance indicators such as speed, back strength, change of direction (COD), and countermovement jump (CMJ). This study aims to contribute to the development of scientifically grounded training programs to support performance improvement in youth football players.</p><p><strong>Methods: </strong>A quantitative research design was employed in this study, specifically a randomized pretest-posttest controlled experimental design. Twenty male youth football players, aged 11-13 years, who voluntarily participated in the study were randomly allocated to either the experimental group (EG; n = 10) or the control group (CON; n = 10). The EG participated in a running-based HIIT program three times per week for four weeks by replacing a low-to-moderate-intensity technical-tactical segment of their regular football training, whereas the CON continued with only regular football training during this period without any additional training volume. The players underwent RSI, 10 m, 20 m, and 30 m sprint tests, back strength tests, the Illinois Agility Test, and CMJ tests both before the training sessions and at the end of the four-week intervention.</p><p><strong>Results: </strong>According to the repeated-measures ANOVA results, pretest values did not differ significantly between the groups (p > .05). Over the 4-week period, significant improvements with large effect sizes were observed in RSI, sprint performance (10, 20, 30 m), back strength, COD, and CMJ tests (p < .05; ηp² = 0.29-0.55). Significant group × time interactions were also detected for all variables, again with large effect sizes (p < .05; ηp² = 0.20-0.30), indicating greater improvements in the EG compared to the CON. However, despite these favourable within-group changes, between-group post-test comparisons did not reach statistical significance.</p><p><strong>Conclusions: </strong>This study revealed that a 4-week HIIT intervention applied to youth male football players had positive effects on the RSI and motor abilities, as evidenced by large within-group improvements and significant group × time interactions, despite the absence of statistically significant between-group post-test differences.

背景:本随机对照试验的目的是确定为期四周的跑步高强度间歇训练(HIIT)干预对青少年足球运动员反应性力量指数(RSI)和运动能力的影响。在此背景下,在常规足球训练之外实施的基于跑步的HIIT协议的贡献,在速度、背部力量、方向变化(COD)和反向跳跃(CMJ)等性能指标上进行了评估。本研究旨在促进科学训练计划的发展,以支持青少年足球运动员的表现提高。方法:采用定量研究设计,即随机前测后测对照实验设计。20名自愿参加研究的11-13岁男性青少年足球运动员随机分为实验组(EG, n = 10)和对照组(CON, n = 10)。EG组每周进行3次跑步式HIIT训练,持续4周,取代了常规足球训练中低到中等强度的技战术部分,而CON组在此期间只进行常规足球训练,没有任何额外的训练量。运动员在训练前和四周干预结束时分别进行了RSI、10米、20米和30米短跑测试、背部力量测试、伊利诺伊敏捷性测试和CMJ测试。结果:根据重复测量方差分析结果,组间前测值无显著差异(p < 0.05)。在4周的时间里,在RSI、冲刺表现(10、20、30米)、背部力量、COD和CMJ测试中观察到显著的大效应改善(p)。本研究显示,对青少年男性足球运动员进行为期4周的HIIT干预对RSI和运动能力有积极影响,尽管组间测试后差异没有统计学意义,但组内改善和组间显著的交互作用证明了这一点。这些发现表明,HIIT方案应该作为提高年轻运动员爆发力、COD和整体功能表现的有效策略纳入训练计划。试验注册:由于伦理审批和注册处理过程中的行政延误,该随机对照试验于2025年7月16日在ISRCTN (ISRCTN45188963)回顾性注册。

Background: Increased thoracic kyphosis (TK) in adolescence can negatively affect posture, balance, and quality of life (QoL). While conventional corrective exercises (CE) are commonly used, Dynamic Neuromuscular Stabilization (DNS), based on developmental kinesiology, has shown potential as a targeted intervention. This study aims to compare the effects of DNS and conventional CE on TK angle, dynamic balance, and QoL in adolescent boys with increased TK.
Methods: In this single-blind randomized controlled trial, 60 male adolescents aged 14-16 years with increased TK were randomly assigned to three groups: DNS, conventional CE, or control. The DNS and CE group completed six sessions per week (three supervised and three home-based) for 8 weeks and control group continues their normal life. TK angle was measured using a Spinal Mouse device, dynamic balance was assessed with the Y-Balance Test, and QoL was evaluated using the SF-36 questionnaire.
Results: Analysis revealed that both the DNS and conventional exercise (CE) groups showed statistically significant improvements in all measured outcomes, including thoracic kyphosis (TK) angle, dynamic balance, and quality of life (QoL) compared to the control group (p < 0.05). Furthermore, while the DNS group demonstrated significantly greater improvements than the CE group in TK angle and dynamic balance (p < 0.05), the difference in QoL between the two intervention groups was not statistically significant.
Conclusion: DNS exercises were more effective than conventional CE in improving posture, balance, and QoL in adolescents with increased TK.
Trial registration: This trial was registered in the Iranian Registry of Clinical Trials (IRCT) under the registration code IRCT20240907062968N5. Registration Date: 13/05/2025.
