Abstract

Triathlon is one of the most flourishing sports in the world. This study aimed to analyze the acute effects of physiological markers and subjective perception variables in amateur trained athletes. Participated in the present study 8 male endurance triathletes with race experience. The injury markers and oxidative stress parameters were investigated in the blood plasma and measured at baseline and post-race. Heat, comfort, and humidity perception, and Borg ratings of perceived exertion were measured during the baseline, transition area, and post-race. Descriptive and inferential statistics were used with significance set as p<0.05. The variables of injury and muscle fatigue presented a significant increase comparing the baseline and post-race data, CK (p= 0.005; d= 5.7), LDH (p= 0.004; d= 1.3) and lactate (p< 0.001; d= 7.2). It was observed a significant increase in CP (p= 0.021; d= 2.2) and a significant decrease in DPPH (p= 0.002; d= -1.4) in post-race, no significant changes in LP (p= 0.217; d= 0.6) and TT (p= 0.881; d= -0.1) oxidative stress markers was verified. A significant increase (Δ% = 30.95, p = 0.001; d = 6.8) was observed in urine temperature and color (range [1-7], p = 0.039). Even with the significant increase in fatigue, with a significant increase in the injury markers, oxidative stress markers suggested a good antioxidant defense. It was observed an increase in exertion and heat perception, as well as a reduction in heat comfort and skin wetness.
巴西铁人三项耐力赛中的急性生理反应
铁人三项是世界上最繁荣的运动之一。本研究旨在分析业余训练运动员的生理指标和主观知觉变量的急性效应。本研究以8名有比赛经验的男子铁人三项耐力运动员为研究对象。研究了血浆损伤标志物和氧化应激参数,并在基线和赛后进行了测量。在基线、过渡区和赛后测量热、舒适和湿度感知,以及感知运动的博格评分。采用描述性统计和推断性统计,p<0.05为显著性。与基线和赛后数据相比,损伤和肌肉疲劳的变量显着增加,CK (p= 0.005;d= 5.7), LDH (p= 0.004;D = 1.3)和乳酸(p< 0.001;d = 7.2)。观察到CP显著增加(p= 0.021;d= 2.2), DPPH显著降低(p= 0.002;d= -1.4), LP无显著变化(p= 0.217;d= 0.6)和TT (p= 0.881;D = -0.1)氧化应激标记物得到验证。显著增加(Δ% = 30.95, p = 0.001;尿温、尿色D = 6.8)(范围[1-7],p = 0.039)。即使疲劳显著增加,损伤标志物显著增加,氧化应激标志物表明有良好的抗氧化防御。观察到运动和热感知的增加,以及热舒适和皮肤湿润程度的降低。
