The Effect Of 8-week Altitude Training On EPO And CGRP Etc. Of Elite Male Rowers

Rowing is a sport, based on high-intensity aerobic capacity and a reasonable technical movement forward to promote the boat. Large number of studies found that a variety of rowing test, the aerobic energy supply to total energy supply of 67-88%. Altitude training can effectively improve the rowing athlete's aerobic capacity, so it has become the primary means of training in rowing. Altitude Training is a purpose and a plan for the athlete with a suitable organization to altitude regions to engage in regular exercise training specific approach.Currently most period of the altitude training on the rowers is 3-5 weeks.8 weeks long aerobic capacity of altitude training for athletes and related indicators have not yet seen. This study discusses erythropoietin (EPO) and red blood cell system, as well as calcitonin gene-related peptide (CGRP) and blood pressure and other related indicators of the study during 8 weeks' altitude training, summes up male rowers 8 weeks altitude training EPO, CGRP changes in laws and other indicators as well as EPO and red blood cell (RBC), CGRP, and the relationship between blood pressure. In addition, the adaptation to high altitude environmen of the rowers with repeated experience of altitude training and the others with initial altitude training is different.This study tries to sum up the difference of EPO, CGRP and other changes of on the distinction between the rowers, and deduces the possible changes in the internal mechanisms to provide assistance and reference for sports training.Objectives:(1) Test and Analysis of 8-week altitude training before, during and after elite male rowers EPO and CGRP changes, and summarize a certain pattern.(2)Research the difference about EPO and CGRP between the rowers of with repeated experience of altitude training and the others with initial altitude training.(3)Study degree of correlation between EPO and CGRP, as well as the intrinsic link between them.(4) explore the correation between EPO and hemoglobin,as well as CGRP and Spo2.Methods:(1) Subject and groups:12 athletes of Shanghai Men's Rowing Team for National Games 2009, the eleventh. According to whether they participated in high altitude training, the rowers are divided into two groups, Group A with multiple altitude training experience (6 athletes), Group B was the first time to participate in high altitude training(6 athletes).(2) Training plan:Jan 16 2009-March 15,2009 in Huize Yunnan (2210 m) for training.(3) Indicators and methods:â‘ EPO; RBC, Hgb, Hct, MCV and so on. Arrange for the test in accordance with the training phase.â‘¡CGRP (test according to the training phase); heart rate in the morning (test on each training day); oxygen saturation (test on each training day); blood pressure (test weekly).(4)statistical methods:We analysis all data by SPSS13.0 statistical software packages and Microsoft Excel software. Altitude Training 12 athletes before, during and after a single-factor analysis of variance, group A, B using an independent samples T test. P<0.05 indicates significant difference, P<0.01 indicatesvery significant differences. The correlation between EPO and RBC as well as the level of CGRP and blood pressure are analysed by Bivariate correlation. Results:EPO levels of 12 athletes,8-week high altitude training at the second day have risen 27.21 percent, at the 8th week have risen 8.37 percent, at the 2 weeks after altitude training have risen 21.92%; Group A and Group B of EPO levels at the second day were increased by 8.17% and 56.01%, at the 8th week were increased by-3.65% and 26.65%, at the 2 weeks after the altitude training were increased by 4.76% and 48.02%.2) 12 athletes CGRP levels in 8-week high altitude training in the first two days increased by 14.98% at the 8th week increased by 25.42%, at the 2 weeks after altitude training have risen 33.27%; Group A and Group B the level of CGRP at the second day were increased by-11.34% and 53.5%, at the 8th week were increased by 26.63% and 23.62%, at the 2 weeks after altitude training have risen 7.54%, respectively, and 70.93%. (3) Before, during and after the 8 weeks altitude training, EPO, and BRC of 12 athletes negative correlation, EPO, and MCH were positively correlated (r=0.263); CGRP positive correlation with systolic blood pressure. (4) In the total training cycle, EPO and CGRP of the 12 athletes is positive correlation (r= 0.348). The corrleation of group A between EPO and CGRP is more closely associated than group B.Conclusions:(1) 8 weeks'altitude training is different from the normal altitude training, which may affected by the eight-week high altitude training, time and training rhythm arrangements. (2) 8 weeks of altitude training can effectively improve the athletes Department of EPO and red blood cells and other indicators, which improve aerobic capacity; athletes with initial altitude training are more sensitive to the plateau environment, physiological reaction is more severe; However, benefits lost more quickly; and athletes with repeated altitude training are less effective, but can consolidate and maintain. (3) In the course of eight weeks of altitude training, CGRP increase, which is a special change to adapt to the needs of the plateau; CGRP's change is related with the changes of blood pressure, blood oxygen saturation. (4) EPO and CGRP in different stages have different relationship, but overall is a positive correlation; this may be due to EPO's release increased lead blood viscosity increases, so as feedback CGRP's release also increased, which require further study.Suggestions:(1)Eight weeks of 2210 meters of altitude training is different from the conventional high altitude training. We should pay attention to physiological, biochemical changes, in order to objectively judge the effects of altitude training. (2) The adaptation and the benefits of altitude training betwwen athletes with repated altitude training experience and athletes with initial altitude training were different,so we should make differenttraining plans and programs for differrent athletes..(3) 8 weeks'altitude training at 2210m can serve as a rowing training methods of physical reserves, and can also provide a reference for other sports.
