balance training with 3 visits per week made up of 10 minutes of dynamic stretching, 5 minutes of unipedal stance, and 5 minutes of upper limb stretching. FMD of the brachial and popliteal artery were measured with a 12-MHz linear phase array ultrasound transducer before and after the intervention. RESULTS: After the intervention, the boxing group showed a significant increment on brachial FMD by 2.4% (p = 0.001) and popliteal FMD by 2.8% (p = 0.043), while no statistical differences were found in the control group for brachial FMD (p = 0.181) and popliteal FMD (p = 0.538). CONCLUSION: Boxing training is a suitable exercise alternative to improve endothelial function in the upper and lower extremity of individuals with prehypertension.

平衡训练，每周3次，包括10分钟的动态拉伸，5分钟的单脚站立和5分钟的上肢拉伸。干预前后分别用12 mhz线性相控阵超声换能器测量肱动脉和腘动脉FMD。结果:干预后，拳击组肱FMD增加2.4% (p = 0.001)，腘窝FMD增加2.8% (p = 0.043)，而对照组肱FMD (p = 0.181)和腘窝FMD (p = 0.538)无统计学差异。结论:拳击训练是改善高血压前期患者上肢和下肢内皮功能的一种合适的运动选择。作者:Paulina Caraveo, Francisco Morales-Acuna, Andrea Rico, Carlos Rehbein, Manuel Gomez, Lisa Rodriguez, Alvaro N.

flexed, p=0.93). Dancers showed greater dynamic US femoroacetabular translation when compared to non-dancer athletes in both the NF position (5.0±2.57 mm, 4.2±2.50 mm; p=0.04) and EER flexed position (6.0±2.53 mm, 5.2±2.41 mm, respectively; p=0.04). CONCLUSION: Acetabular dysplasia was not associated with increased dynamic US femoroacetabular translation in this cohort. Dancers showed increased US femoroacetabular translation compared to non-dancer athletes. This finding is likely related to increased ligamentous laxity and stretched ligaments inherent to dance training. Future research is warranted to collect data in asymptomatic dancers with and without acetabular dysplasia.

It is documented that intense periods of soccer can induce oxidative stress, the negative effects of which can compromise performance. However, few studies have explored the potential association between exercise-induced oxidative stress and training load intensity. PURPOSE: The aim of the study was to quantify oxidative stress relative to indicators of high-intensity training load in a cohort of professional soccer players throughout different phases of a competitive in-season. METHODS: Ten professional soccer players (age: 23±2yrs; body mass: 83.5±6.2kg; stature: 181.3±5.3 cm; V O2max: 57.2±6.7mL·kg·minˉ ), representatives from an English Football League One team, participated in the study. Training load was assessed at three time points throughout a competitive in-season (T1: early in-season; T2: mid-season; T3: end of in-season [1, 16 & 32 microcycle]) using global positioning system (GPS) and heart rate (HR) based methods to quantify external (HETL) and internal high-intensity training load (HITL). Urine samples were collected at each time point and analysed for malondialdehyde (MDA) as a biomarker of oxidative stress. Data normalised to creatinine. Results presented as M ± SD. RESULTS: High-intensity training load varied significantly throughout the competitive in-season and was significantly higher at T2 compared to T1 (HETL: 18.56 ± 7.30 mmin vs. 6.72 ± 2.62 mmin, an increase of 11.84 mmin, 95% CI [4.33, 19.36], p = .004; HITL: 60 ± 34 %Time spent > 80% HRmax vs. 23 ± 15 %Time spent > 80% HRmax, an increase of 37 %Time > 80% HRmax, 95% CI [13, 60], p = .004; T2 vs. T1, respectively). Urinary MDA concentrations decreased significantly throughout the competitive in-season, x (2) = 6.889; p = .032, (T1: 0.76 ± 0.90 μMmmol vs. T3: 0.18 ± 0.12 μMmmol, Z = -2.192, r = .52, p = .028). No significant correlations were observed between indicators of high-intensity training load and MDA. CONCLUSION: Chronic soccer training appears to promote an adaptive response as oxidative stress was attenuated over the competitive in-season, irrespective of the intensity of the training load. Monitoring urinary MDA may be a useful tool to provide coaches and sports scientists an insight into adaptive or maladaptive responses throughout a competitive season in soccer.
有证据表明，激烈的足球比赛会引起氧化应激，其负面影响可能会影响表现。然而，很少有研究探讨运动诱导的氧化应激和训练负荷强度之间的潜在联系。目的:本研究的目的是量化一组职业足球运动员在竞争性赛季不同阶段的高强度训练负荷指标的氧化应激。方法:10名职业足球运动员(年龄:23±2岁;体重:83.5±6.2kg;身高:181.3±5.3 cm;V O2max: 57.2±6.7mL·kg·min)，来自英国足球甲级联赛球队的代表参加了这项研究。在整个竞争性赛季的三个时间点评估训练负荷(T1:赛季早期;T2:复发;T3:赛季末[1,16 & 32微周期])，使用基于全球定位系统(GPS)和心率(HR)的方法量化外部(HETL)和内部高强度训练负荷(HITL)。在每个时间点收集尿液样本，并分析丙二醛(MDA)作为氧化应激的生物标志物。数据归一化为肌酐。结果以M±SD表示。结果:高强度训练负荷在整个竞技赛季中变化显著，T2时明显高于T1 (HETL: 18.56±7.30 min vs. 6.72±2.62 min，增加11.84 min, 95% CI [4.33, 19.36]， p = 0.004;HITL: 60±34%的时间花费> 80% HRmax vs. 23±15%的时间花费> 80% HRmax，增加37%的时间花费> 80% HRmax, 95% CI [13,60]， p = 0.004;分别为T2和T1)。尿丙二醛(MDA)浓度在整个竞争季节显著下降，x (2) = 6.889;p = 0.032， (T1: 0.76±0.90 μMmmol vs T3: 0.18±0.12 μMmmol, Z = -2.192, r = 0.52, p = 0.028)。高强度训练负荷指标与MDA无显著相关。结论:无论训练负荷的强度如何，慢性足球训练似乎可以促进适应性反应，因为氧化应激在竞争性赛季中被减弱。监测尿丙二醛可能是一个有用的工具，为教练和运动科学家提供一个洞察适应或不适应的反应在整个竞争赛季的足球。
