摘要

目的：探討動態恢復對漸增性衰竭運動後血液中淋巴細胞數目及亞群比例變化情形。方法：本實驗對象為20位高中田徑隊男性選手，其中10名為動態恢復組（平均年齡：16.2 ± 1.1歲，最大攝氧量：57.3 ± 8.7ml‧min-1‧kg-1）而10名為安靜休息組（平均年齡：16.6 ± 1.0歲，最大攝氧量：58.5 ± 9.0 ml‧min^-1‧kg^-1）。兩組在跑步機上進行漸增衰竭運動，動態恢復組在衰竭運動後，再接著20分鐘低強度（35% VO2max）運動，而安靜休息組則採坐姿休息。於運動前、運動後立即、運動後20分鐘及運動後2小時進行採血，以便分析血液中淋巴細胞數目和T淋巴亞群、B細胞及NK細胞比例。所得資料以混合設計二因子變異數進行分析。結果：動態恢復組CD3（上標 +）／CD4（上標 +）比例在運動後2小時顯著低於靜態恢復組，但兩組均高於運動前值。安靜休息組淋巴細胞數目和NK 細胞比例在運動後2小時，顯著低於運動前值。結論：年輕田徑選手在漸增衰竭運動後，恢復期淋巴細胞數目和NK細胞比例會減少。雖然，在單次漸增衰竭運動後進行動態恢復對後天性免疫系統比較無影響，但能緩和激烈運動後先天性免疫系統下降的趨勢。

Purpose: The present work investigated how active recovery influenced blood lymphocyte and lymphocyte subsets following maximal exercise. Method: Fifteen senior high school male athletes participated in this study. They were divided in two groups according to VO2max values: active recovery, AR (N=10, age=16.2 ± 1.1 years, VO2max values=57.3 ± 8.7ml‧min^-1‧kg^-1); rest recovery, RR (N=10, age=16.6 ± 1.0 years, VO2max values=58.5 ± 9.0 ml‧min^-1‧kg^-1). Both groups performed incremental exercise until volitional exhaustion on the treadmill. After exhaustive exercise AR jogged further 20 min at 35% VO2max, whereas RR sited, during recovery period. Venous blood samples were collected pre-exercise and then immediately, 20- and 120- minutes post-exercise. Lymphocyte count and proportion of T lymphocyte subsets, B cell and NK cell were measured. Data were analyzed using mixed design two-way ANOVA and repeated one-way ANOVA. Results: The ratio of CD3+/CD4+ at 120min post-exercise was significantly different between AR and RR, and both groups were higher than pre-values. At 120min post-exercise, the lymphocyte count and the ratio of NK cells at RR was significantly decreased below baseline. Conclusion: The lymphocyte count and the ratio of NK cells declined below pre-value after maximal exercise. Although active recovery did not have influence on adaptive immunity but it could attenuate the downside of innate immunity after strenuous exercise.
