The aim of this study was to evaluate the influence to acute exercises performed in different intensities with volume equalized (5 km) on indices of cardio-inflammatory health. Twelve physically active male subjects (age, 23.22±5.47 years; height, 174.75±5.80 m; weight, 75.13±6.61 kg; maximal oxygen uptake, 52.92 mL/kg/min), after determination of peak oxygen uptake (VO) and the speed associated with VO (sVO), completed two randomly experimental trials: high-intensity intermittent exercise (HIIE: 1:1 at 100% sVO) and moderate-intensity continuous exercise (MICE: 70% sVO). Brain-derived neurotrophic factor (BDNF), adiponectin and plasminogen inhibitor-1 (PAI-1) data were analyzed pre, immediately, and 60 min after the exercise session. Statistical analysis comparisons between moments and between HIIE and MICE were performed using a mixed model and statistical and significance was set at <5%. PAI-1 presented an effect for time from pre to immediately after exercise moment (<0.018) and from immediately to 60 min after exercise moment (<0.001) only in MICE. BDNF presented an effect for time from pre to immediately after exercise to HIIE (<0.022) and from immediately to 60 min after exercise to MICE (<0.034). HIIE promotes BDNF increase and that there is negative correlation between PAI-1 concentrations and BDNF in both protocols in healthy sportsmen, favoring an anti-atherogenic profile.
本研究的目的是评估在运动量相等(5公里)的情况下,不同强度的急性运动对心脏炎症健康指标的影响。12名身体活跃的男性受试者(年龄23.22±5.47岁;身高174.75±5.80厘米;体重75.13±6.61千克;最大摄氧量52.92毫升/千克/分钟),在测定峰值摄氧量(VO)和与VO相关的速度(sVO)后,完成了两项随机实验试验:高强度间歇运动(HIIE:1:1,强度为100% sVO)和中等强度持续运动(MICE:70% sVO)。在运动前、运动结束即刻和运动结束60分钟后分析脑源性神经营养因子(BDNF)、脂联素和纤溶酶原激活物抑制剂-1(PAI-1)的数据。使用混合模型对不同时刻以及HIIE和MICE之间进行统计分析比较,设定统计学显著性为<5%。仅在MICE中,PAI-1在运动前到运动结束即刻(<0.018)以及运动结束即刻到运动结束60分钟后(<0.001)呈现出时间效应。BDNF在HIIE中运动前到运动结束即刻(<0.022)以及在MICE中运动结束即刻到运动结束60分钟后(<0.034)呈现出时间效应。在健康运动员中,HIIE促进BDNF增加,并且在两种运动方案中PAI-1浓度与BDNF之间均存在负相关,有利于抗动脉粥样硬化状态。
