Background Previous studies were conducted only on elite athletes, and they investigate acute training responses of cardiac troponin I (CTnI). However, cardiac troponin was found to be elevated in young and inexperienced athletes than adults, and immature myocardium is more susceptible to injury, which needs further consideration. Aim Therefore, we aimed to observe the association between CTnI and cardiovascular parameters in response to chronic endurance training adaptation in young athletes. Methods Fifteen participants aged (19.5±1.3) years were selected and placed in endurance running at 70%–80% HRmax intensity for 35 min per training for the first week and additional 2 min each week from the second to the last week for 12 weeks. Serum cardiac troponin and cardiovascular parameters were assessed at pre-training and after 12 weeks of training. Result We find a significant CTnI level (p<0.05) and it is positively correlated with systolic blood pressure (BP) (r=0.425). Moreover, CTnI was statistically significant (p<0.01) and positively associated with mean arterial pressure (r=0.516) with a moderate correlation. Besides, CTnI showed a significant (p<0.001) and positive relationship with resting heart rate (r=0.605) and a moderate correlation. We did not find a significant relationship between CTnI and diastolic BP in response to endurance training adaptation. Conclusion In conclusion, serum CTnI was significantly and positively associated with cardiovascular parameters in young amateur athletes in response to 12-week endurance training adaptation.

受过中等训练的年轻业余运动员在 12 周耐力训练后心肌肌钙蛋白 I 与心血管参数之间的关联

背景 以前的研究仅针对优秀运动员进行,他们调查了心肌肌钙蛋白 I (CTnI) 的急性训练反应。然而,发现年轻和缺乏经验的运动员的心肌肌钙蛋白高于成人,未成熟的心肌更容易受到损伤,这需要进一步考虑。目的因此,我们旨在观察 CTnI 与心血管参数之间的关联,以应对年轻运动员的慢性耐力训练适应。方法 选择 15 名(19.5±1.3)岁的参与者,在第一周进行 70%~80% HRmax 强度的耐力跑,每次训练 35 分钟,从第二周到最后一周每周增加 2 分钟,持续 12 周. 在训练前和训练 12 周后评估血清心肌肌钙蛋白和心血管参数。结果 我们发现 CTnI 水平显着(p<0.05),并且与收缩压(BP)呈正相关(r=0.425)。此外,CTnI 具有统计学意义(p<0.01)并且与平均动脉压呈正相关(r=0.516),具有中等相关性。此外,CTnI 与静息心率呈显着(p<0.001)正相关(r=0.605),中度相关。我们没有发现 CTnI 和舒张压之间的显着关系响应耐力训练适应。结论 总之,血清 CTnI 与年轻业余运动员在 12 周耐力训练适应后的心血管参数显着正相关。此外,CTnI 具有统计学意义(p<0.01)并且与平均动脉压呈正相关(r=0.516),具有中等相关性。此外,CTnI 与静息心率呈显着(p<0.001)正相关(r=0.605),中度相关。我们没有发现 CTnI 和舒张压之间的显着关系响应耐力训练适应。结论 总之,血清 CTnI 与年轻业余运动员在 12 周耐力训练适应后的心血管参数显着正相关。此外,CTnI 具有统计学意义(p<0.01)并且与平均动脉压呈正相关(r=0.516),具有中等相关性。此外,CTnI 与静息心率呈显着(p<0.001)正相关(r=0.605),中度相关。我们没有发现 CTnI 和舒张压之间的显着关系响应耐力训练适应。结论 总之,血清 CTnI 与年轻业余运动员在 12 周耐力训练适应后的心血管参数显着正相关。605)和中等相关性。我们没有发现 CTnI 和舒张压之间的显着关系响应耐力训练适应。结论 总之,血清 CTnI 与年轻业余运动员在 12 周耐力训练适应后的心血管参数显着正相关。605)和中等相关性。我们没有发现 CTnI 和舒张压之间的显着关系响应耐力训练适应。结论 总之,血清 CTnI 与年轻业余运动员在 12 周耐力训练适应后的心血管参数显着正相关。
