本文主要目的：一、藉助無氧閾值（Mader）做為訓練強度的設定；二、應用無氧閾值做為訓練效果評價。本研究以國立三重商工田徑隊8任中距離女選手為對象，年齡18.5±3.0歲，身高161±5.0公分，體重49.3±6.1公斤，訓練年齡6.0±4.2年。測試方法是採用（Mader, 1976）階梯式測試法，選手們先經前測（2-4mmol/L檢測）後，再經5週的訓練進行後測（訓練效果評估），後測是依據生理適應原理（4-6週）為人體的適應期，測量及記錄選手每階之血乳酸、心跳率。實驗所得之各項生物參數以統計軟體SPSS for Windows 10.0版，進行t-test。本研究結果顯示在比較兩次測試曲線移動，後測（Test-2）血乳酸值低且向右移且顯著性達.p<.001；心跳率在前測（Test-1）與後測（Test-1）達到p<.05的顯著性差異。經Laktat-Ecprot乳酸閾值軟體分析，有氧閾值2mmol/L的速度在Test-1與Test-2之間差異0.4m/s，心跳率差異在6min□，而無氧閾值4mmol/L的速度在Test-1與Test-2之間差異0.2m/s，心跳率差異在 6min□，由以上結果得知選手們的體能增加及乳酸代謝率提高了。

The purposes of this study were as follows: (1) Use anaerobic threshold as the standard of training intensity; (2) Assess the effects of it. 8 female middle-distance contestants in SCVS were selected as the subjects of this study. The average age, height, weight, and training age are 18.5±3.0 years, 161.4±5.0 cm, 49.3±6.1 kg and 6.0±4.2 years, respectively. The pretest-posttest design was employed in this study. All contestants accepted the 2-4mmol/L examine as the pretest. According to physiological adoption theory, posttest was conducted 5 weeks later. Lactic acid the HR are measured and recorded in each stage. The data were analyzed by t-test, SPSS For Windows 10.0 was implemented. The result showed that: lactic acid values showed significant differences (p<.01) in the posttest; also significant in the HR (p<.05). Data were also analyzed by Laktat-Ecprot lactic acid threshold software, the difference between pretest and posttest of aerobic threshold (2mmol/L) rate, Hr, and anaerobic threshold (4mmol/L) rate are 0.4m/s, 6min□, and 0.2m/s, respectively. In conclusion, we could see the improvement in physical strength and lactic acid metabolic rate among the contestants.
