【摘要】：目的:對受試者進(jìn)行改良CO吸入法測試血紅蛋白總量(t Hb)后,在不同時間點(diǎn)測試最大攝氧量(VO2max)和無氧閾(AT),分析其變化趨勢,并對CO在體內(nèi)的代謝情況進(jìn)行研究。方法:10名網(wǎng)球?qū)ｍ?xiàng)大學(xué)生,19~21歲,肘靜脈取血測試血紅蛋白(Hb)等基礎(chǔ)值,直接測試法測試VO2max;連續(xù)3周對所有受試者進(jìn)行CO吸入法測試t Hb后,在不同時間點(diǎn)(第1周即刻、第2周6小時和第3周12小時)測試受試者VO2max和AT,觀察這些指標(biāo)隨時間的變化曲線;第4周,在10名受試者吸入少量CO后的6 min、3 h、6 h、9 h、12 h測試受試者呼出氣CO和血液中碳氧血紅蛋白(Hb CO)的濃度變化曲線,其中5名受試者在吸入CO后進(jìn)行2小時網(wǎng)球運(yùn)動,另外5名受試者安靜休息。結(jié)果:在CO吸入法測試t Hb后,所有受試者VO2max和AT顯著下降達(dá)9.4%左右(P0.01),在第2周的6 h時間點(diǎn)開始恢復(fù),但仍然低于基礎(chǔ)值(P0.05),在第3周的12 h時間點(diǎn)才完全恢復(fù)。呼出氣CO和血液中Hb CO濃度在CO吸入后即顯著升高,在6 min達(dá)到最高點(diǎn)后即開始下降,直到6 h時間點(diǎn)才基本恢復(fù)正常,其中運(yùn)動組CO在體內(nèi)的恢復(fù)速度要快于安靜組。結(jié)論:CO的吸入會在短時間內(nèi)(6 h)顯著降低受試者的VO2max和AT等反應(yīng)有氧工作能力的指標(biāo),在6 h之后開始逐漸恢復(fù);CO吸入后,呼出氣CO濃度和血液中Hb CO濃度的上升會經(jīng)過正常代謝而排出體外,適當(dāng)運(yùn)動有助于體內(nèi)CO代謝速度的提高。
[Abstract]:Objective: to test the maximal oxygen uptake (VO _ 2max) and anoxic threshold (ATN) at different time points after the modified CO inhalation method was used to measure the total hemoglobin t Hb), to analyze the change trend and to study the metabolism of CO in vivo. Methods Twenty ten tennis college students, aged 19 to 21, were tested for hemoglobin and HB by cubital vein, and VO 2max was measured by direct test. T HB was measured by CO inhalation for 3 consecutive weeks, and at different time points (immediately after week 1). In week 2, week 6 and week 3, week 12, the subjects were tested for VO2max and AT.The curves of these parameters were observed over time; at week 4, The change curves of CO exhalation and hemoglobin (HB) in blood were measured at 6 min, 3 h, 6 h, 9 h and 12 h after CO inhalation in 10 subjects, and 5 subjects were given 2 hours tennis exercise after inhaling CO. The other five subjects rested quietly. Results: after testing t HB by CO inhalation, the levels of VO2max and AT in all subjects decreased significantly by about 9.4% P0.01A, and began to recover at 6 h after the second week, but were still lower than the base value (P0.05), and only fully recovered at 12 h after the 3rd week. The concentration of exhaled CO and HB CO in blood increased significantly after CO inhalation and began to decrease after 6 min reaching the highest point. The CO recovery rate in the exercise group was faster than that in the quiet group until the time point of 6 h. Conclusion inhaled fraction of CO could significantly decrease the aerobic capacity of VO2max and AT in a short period of time, and then gradually recover after inhaling CO 6 h later. The increase of CO concentration in exhalation and HB CO in blood will pass through normal metabolism and be discharged out of the body. Proper exercise is helpful to the increase of CO metabolism velocity in vivo.
