單次無氧運動對血液肌酸激酶、乳酸脫氫酶及嗜中性白血球之影響

Abstract

目的：本研究探討大學男性進行單次無氧運動對血液肌酸激酶、乳酸脫氫酶及嗜中性白血球之影響。方法：以健康男性大學生27名，年齡20.1±0.8歲，身高172.3±5.2公分，體重66.9±7.5公斤為對象，受試者盡全力完成Wingate 30秒無氧動力測驗，而在安靜時、運動後5分鐘及運動後24小時抽血檢驗，並以相依樣本單因子變異數分析比較安靜時、運動後5分鐘及運動後24小時之血液中肌酸激酶、乳酸脫氫酶及嗜中性白血球值，是否有顯著差異。結果：在肌酸激酶值方面，運動後5分鐘明顯高於安靜時(226.4±144.3vs. 192.2±129.9U/L, p<.05)，以及運動後24小時明顯高於安靜時(230.1±122.1vs. 192.2±129.9U/L, p<.05)；在乳酸脫氫酶值方面，運動後5分鐘明顯高於安靜時(151.9±28.9vs. 130.1±23.0U/L, p<.05)，以及運動後5分鐘明顯高於運動後24小時(151.9±28.9vs. 129.2±23.8U/L, p<.05)；在嗜中性白血球值方面運動後5分鐘明顯高於安靜時(4619.4±1321.2vs. 3690.8±866.2/μL, p<.05)，以及運動後5分鐘明顯高於運動後24小時(4619.4±1321.2vs. 3387.0±780.9/μL, p<.05)。結論：進行單次無氧運動後5分鐘，在肌酸激酶及乳酸脫氫酶值方面，肌肉代謝指標明顯上升，可能反應出立即性的肌肉損傷；另外，在乳酸脫氫酶值方面，運動後24小時明顯下降，意味著過多的乳酸已排除體外。在嗜中性白血球值方面，無氧運動後的5分鐘明顯上升以及24小時後的明顯下降，代表運動後身體潛在性肌肉損傷，但在休息24小時後已恢復正常。

Purpose: The purpose of this study was to compare effect of a single bout of Wingate power exercise on blood creatine kinase, lactate dehydrogenase and neutrophil in male university students. Methods: Twenty-seven healthy male ( the average age was 20.1 ± 0.8 y, the average height was 172.3 ± 5.2 cm, the average weight was 66.9 ± 7.5kg). After they finish Wingate 30 sec test for their maximum strength. Venous blood samples were collected immediately before on anaerobic exercise and after 5 minutes and 24 hours. Serum levels of CK, LDH and neutrophil were detected. To analysis data by used descriptive analysis, and One-way Anova (p<.05). Results: CK was significantly increased 5 minutes postexercise as compared with pre-exercise (226.4 ± 144.3 vs. 192.2 ± 129.9 U/L, p<.05). And it was significantly increased 24 hours postexercise as compared with pre-exercise (230.1 ± 122.1 vs. 192.2 ± 129.9 U/L, p <.05). LDH was significantly increased 5 minutes postexercise as compared with pre-exercise (151.9 ± 28.9 vs. 130.1 ± 23.0 U/L, p<.05). And LDH was significantly decreased 5 minutes postexercise as compared with 24 hours postexercise (151.9 ± 28.9 vs. 129.2 ± 23.8 U/L, p<.05). Neutrophil was significantly increased 5 minutes postexercise as compared with pre-exercise (4619.4 ± 1321.2 vs. 3690.8 ± 866.2/μL, p<.05). And it was significantly increased 5 minutes postexercise as compared with 24 hours postexercise (4619.4 ± 1321.2 vs. 3387.0 ± 780.9 /μL, p<.05). Conclusions: After 5 minutes single bout of anaerobic exercise, serum CK and LDH were significantly increased, could resulted in muscle damage immediately. But LDH in 24 hours postexercise was significantly decreased and represented to lactic acid excluded our body. Neutrophil was increased 5 minutes postexercise and decreased 24 hours postexercise and represented postexercise muscle damage potentiality. And after 24 hours break it will return to normal.
