[Abstract]:Objective: To study the metabolism of female rowers in Shaanxi Province before and after the winter gas, a comparative study of anaerobic capacity, aims to investigate the effects of training on aerobic capacity and anaerobic capacity of athletes from the physiology angle and its possible causes, to help the coaches to further improve the training plan, improve the level of training so as to provide theoretical reference for me. Rowing team achieved better results in the Thirteenth National Games to make due contributions. Methods: running warm-up, dynamometer for 5mi, heart rate 140-150b/mi, rest 3min after incremental load test. The 120w-150w-180w-210w-240w-270w exercise, each load lasts two minutes, according to personal ability, in the last stage and then to pull end sprint until exhaustion. Rowing ergometer is the main subjects not controllable, requiring coaches beside supervision by breath breath encouragement. Method (Breath by breath) test. The athlete completes preparatory activities, with little rest, breathing masks, Polar table and Metamax 3B heart lung function testing device, and connected pathways. In this process the gas analyzer automatic continuous measurement of gas metabolism index, Polar test heart rate, the result was Metamax 3B recorded and transmitted to the computer automatically save the record. Main indicators of VO2max, relative VO2max, VO2max platform, the largest carbon dioxide output, respiratory rate, oxygen pulse, maximum respiratory quotient, maximum ventilation anaerobic threshold, maximal heart rate, maximal exercise time. Immediately after exercise, 3 min, 5min 15, min 20ul refers to the blood test of lactic acid by concePt2 for 60 seconds. The boat sustained maximum capacity dynamometer test, maximum capacity after exercise test 7,9,11,13min after exercise blood lactic acid. Results: (1) when quiet winter after TV, RR, VE, Petc02, V02,VC02,MET,VE/V02,鍛煎惛鏁堢巼,VD/TV,VO_2/HR 鍧囬珮浜庡啲璁墠(P0.05),PetO_2,RQ 灝忎簬鍐鍓，
