Monitoring and evaluation of young female judo players subjected to different training means and load intensities
By testing the blood lactic acid and heart rate of young female judo players subjected to different training means before a competition,the author evaluated exercise intensities produced by different training means in order to provide a criterion for coaches to arrange training scientifically.Basing her research subject on young judo play-ers in Guangzhou,the author tested their blood lactic acid and heart rate after each competition in a teaching compe-tition class,as well as their heart rate after a real competition training class and a dedicated strength training class,and then performed a comparative analysis on the results together with related test results acquired by other schol-ars.Research results: 1) their blood lactic acid after a teaching competition is(8.01±2.11) mmol/L;2) their average heart rate and highest heart rate after warm-up before a teaching competition and the first round of teaching compe-tition are respectively(121±11) beats/min,(146±13) beats/min and(160±7) beats/min,(183±10) beats/min;their average heart rate and highest heart rate after warm-up before a real competition and the first round of real competi-tion are respectively(146±14) beats/min,(168±11) beats/min and(158±9) beats/min,(171±11) beats/min;their av-erage heart rate and highest heart rate after dedicated strength training are respectively(159±10) beats/min and(171±10) beats/min.The results indicate the followings: when preparing for a teaching competition,the coach should arrange the opponent and establish the competition atmosphere in such a way that the teaching competition should be made as close to the formal competition as possible;the load intensity for warm-up should be appropri-ately increased in order to achieve the goal of warm-up;high intensity and high quality training classes should be appropriately arranged in order to meet the demand for high intensity movement during a formal competition;there are many heart rate affecting factors,so the blood lactic acid and heart rate had better be tested at the same time in order to accurately determine the exercise intensity.
