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＜.0l) 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^(-1), and 0.2m/s, respectively. In conclusion, we could see the improvement in physical strength and lactic acid metabolic rate among the contestants.
