A Comparative Study Of Structure Andfeatures Of Training Load Between Winter Training And Pre-Competition Training For Shanghai Men’s Rowing Team Preparing For Open Class Eight Oarsof The 2013 National Games Of PRC

Purpose: This paper focuses on the differences of efficiency and rationality of training load arrangement between winter and the pre-competition training. Through a comparative study between the last winter training(12 weeks) and the pre-competition training before the final of 2013 Nation al Games(8 weeks) to analyze thedifferent performance s of training loadof different training period s, so that coaches ma y make appropriate adjustments accordingly.M ethods: 1. Subjects: eight male open-class heavyweight single oar pla yers of Shanghai Rowing Team. 2. Contents: This paper focuses on different training load features of Shanghai men’s rowing eight oars between the last winter training(12 weeks, Dec. 2012 to Feb. 2013) and the pre-competition training(8 weeks, Jun. 3013 to Aug. 2013) before the final game of 2013 National Games. Training load data collection is divided into two aspects. In the load data monitor ing, the length of time is calculated. We mainly record the time length of water training, dynamo meter training, intensive training and core strength training. For the athletes, lactic acid and heart rate is monitored. To collect athletes heart rate(HR) d ata, players wear heart rate meters for every training, and blood lactic acid(Bla) is tested after every training. For the aerobic training, Bla is below 4mmol/L, HR is below 160, while for the anaerobic training, Bla is 4mmol/L above, HR is more than 160. In this paper, the author uses these two indicators to define the aerobic and anaerobic training, thus the effective training time can be counted.The results: 1. The winter training is predominantly aerobic training. The total water aerobic training time is 6510 minutes(32%). The total aerobic d ynamometer training lasts 2100 minutes(11%). The total anaerobic water training is 120 minutes(0.6%). The total anaerobic d ynamometer training is 450 minutes(2%). 2. As for the pre-competition training, the total w ater aerobic training time is 5400 minutes(41%). The total aerobic dynamometer training lasts 1130 minutes(8%). The total anaerobic water training is 1429 minutes(10%). The total anaerobic dynamometer training is 40 minutes(1%). Anaerobic training time length increases significantly, while aerobic training stills accounts for high proportion. The training is dominantly water training. 3. For the winter training, the aerobic training accounts for 43%, and the anaerobic training 3%. The aerobic water trainin g is 543 minutes per week. The total aerobic dynamometer training is 175 minutes per week. The total anaerobic water training is 10 minutes per week. The total anaerobic d ynamometer training is 38 minutes per week.For the pre-competition training, the aerobic training accounts for 49%, and the anaerobic training 10%. The aerobic water training is 675 minutes per week. The total aerobic dynamometer training is 141 minutes per week. The total anaerobic water training is 179 minutes per week.Conclusions: 1. The 12-week long winter training is dominantly aerobic water training, andaerobic dynamo meter training is supplemented. There are sometimes anaerobic dynamometer and water training. The performance curve of 3-stage aerobic training changes like waves. The highest proportion of stage one is aerobic training,. The highest proportion of stage 2 is anaerobic training. 2. The 8-week-long pre-competition training is mainly aerobic training, but anaerobic proportion increases, among which the 7t h week is the highest. The performance curve of pre-competition aerobic training looks like the letter “W”. The proportion of anaerobic training and aerobic training of stage 2 is higher and lower than those of stage one respectively. 3. Both the winter and pre-competition trai ning is mainly aerobic. The proportion of both aerobic and anaerobic training of pre-competition is higher than that of winter training, because before the final game the training amount increases, and aerobic training is valued. This conclusion is in line with the characteristics of rowing enent.
