高強度耐力與肌力運動對血乳酸及血清免疫球蛋白濃度之效應

中文摘要

本研究的目的，在探討高強度耐力與肌力運動，對運動員與非運動員血乳酸及血清免疫球蛋白濃度的效應。本研究受試者共18名，其中9名為運動員平均年齡18.89±0.60 yrs、身高165.22±4.35 cm、體重51.67±4.12 kg及最大攝氧量54.07±2.20 ml/kg/min；另9名為非運動員平均年齡19.11±0.33 yrs、身高158.33±3.81 cm、體重51.33±6.32 kg及最大攝氧量36.54±3.65 ml/kg/min。分別於兩種不同類型，高強度的耐力性（跑步機上跑至衰竭）及肌力性（等速肌力測定儀膝屈伸至疲勞）運動前後，抽取血液檢驗。測驗所得資料，經二因子變異數分析及皮爾遜相關積差係數進行各項考驗。

結果發現：(1)運動員組在最大攝氧量及最大力矩值，皆明顯高於非運動員組（p<0.01）。(2)血乳酸濃度在兩組受試者不同類型運動後，皆明顯升高（p<0.01）。(3)血清IgG、IgA、IgM濃度在高強度耐力性運動後，運動員組達顯著的升高（p<0.01），而非運動員組則無顯著差異；於高強度肌力性運動後，兩組皆無顯著差異。(4)血乳酸與血清IgG、IgA、IgM的濃度，在不同類型運動前後的變化量並無顯著相關。

經過討論之後，得到以下結論：不同類型的高強度運動後，血乳酸濃度顯著升高，可為負荷強度的指標。高強度耐力運動後，運動員免疫力的提升，可能與規律的運動訓練有關。運動前後血乳酸與血清IgG、IgA、IgM的濃度變化並無相關性。

Abstract

The purpose of this study was to compare the effects of intense endurance and strength exercises on the blood lactate and serum immunoglobulin levels between trained and untrained females. There were 9 trained females with average age of 18.89±0.60 yrs, average height of 165.22±4.35 cm, average weight of 51.67±4.12 kg, and average VO2max=54.07±2.20 ml/kg/min. And the other 9 untrained females with average age of 19.11±0.33 yrs, average height of 158.33±3.81 cm, average weight of 51.33±6.32 kg, and average VO2max of 36.54±3.65 ml/kg/min. Subjects were asked to perform both intense endurance and strength exercises (running on a treadmill until exhausted and knee extension and flexion on a Kin-com until fatigue, respectively). Blood samples were collected both before and after exercises. The data was analyzed by the two-factorial ANOVA and Pearson product-moment correlation coefficient.

The following results were found: (1) The VO2max and peak torque of trained were significantly higher than untrained (p<0.01). (2) The blood lactate of both groups was significantly increased after different exercises (p<0.01). (3) The serum immunoglobulin was significantly increased in trained after the intense endurance exercise, but was no significant difference for untrained (p<0.01). (4) There was no significant correlation in the variety of blood lactate and serum immunoglobulin before and after different exercises for both groups.

Conclusions: it could be an index of loading intensity that the blood lactate was significantly increased after different exercises. It is probably related to the regular exercise that the immunity of trained could be enhance after the intense endurance exercise. There was no significant relationship between blood lactate and serum immunoglobulin before and after exercise.
