The Effect Of 8-week( Long Time) Altitude Training On Aerobic Athletic Ability Of Elite Male Rower

Purpose:(1),the athletes blood indexes, gas metabolism, exercise capacity index for statistical analysis and objective evaluation of long altitude training on blood containing oxygen and oxygen capacity of the muscles used to assess aerobic capacity Players change. (2), on many occasions the initial plateau altitude training group and training group were compared to find differences in effects of altitude training, probe the rule. (3) to explore the characteristics of altitude training a long time and with the athletes individual relationship between physiological and biochemical indexes and changes in law, to further improve the rowing altitude training and monitoring to provide reference.Methods:(1) Subjects and groups:Shanghai Men's rowing team of 12 key players for the study, according to the number of altitude training experience, divided into two groups: A group for the many altitude training group, a total of six members; B group for the first altitude training group, a total of 6 team members.(2) Training arrangements:Altitude training is divided into four stages: the first stage (January 16, 2009 -1 23) for the adaptation period, exercise load is the load and small load strength training, the second phase (January 2009 24 -2 12), for the load of climbing, exercise stress is the second largest load and low load strength training, the third phase (February 13, 2009 -3 7 months), the peak load , exercise is a big load capacity, the load intensity and the second largest load strength training, the fourth stage (March 8, 2009 -17 days), the peak load strength, exercise capacity is a big load, big load strength training .(3) Test Specifications:①, blood indexes: include red blood cell count (RBC), hemoglobin (Hb), hematocrit (HCT) and so on.②, gas metabolism: include absolute maximum oxygen uptake (VO2max), the relative maximum oxygen uptake (VO2max/kg), the largest amount of carbon dioxide exhaled (VCO2max), maximum oxygen uptake platform (VO2maxPD), anaerobic threshold oxygen uptake amount (AT-VO2), heart rate, anaerobic threshold (AT-HR) and so on.③, special movement indicators of aerobic capacity: Dynamometer 2km, 6km, six sub-increasing load tests in average speed (average power), sub-row frequency, total score, blood milk (Bla) acid, heart rate (HR ) and so on.(4) statistical methods:All data are used SPSS13.0 statistical software and Microsoft Excel 2003 software for processing and analysis, results are mean±standard deviation ( X__±SD) said. Select One-Way Analysis of Variance and Paired-Samples t Test of two methods to analyze the data. P <0.05 was significantly higher, P <0.01 for the difference is very significant.Results:Changes in red blood cell system:The first week of athletes into the plateau level of the overall Hb fell 5.81%, B group declined more than A group, the second week began to increase, in the fourth week of the peak, the higher up the original before the 9.68%, A group Hb increased by 11.18 %, B group increased 6.92%, after the first week of the next plateau Hb decreased slightly higher than the plateau level before, the second week before the peak higher up 10.32% of the original. A group increased by 9.87%, B group increased 9.43%; higher rate than B group.Changes in aerobic capacity:Plateau was found after the test: Athletes gas metabolism VO2max, VO2max/kg, VCO2max down 5.08%, 2.51%, 9.14%. Group B is greater than A group decrease; VO2maxTp, Time-max increased 41.18%, 0.32%; A group increased 66.7%, 4.32%, B group VO2maxTp increased by 17.4%, while Time-max was decreased by 5.40% . Anaerobic Threshold AT-HR, AT-HRmax% decreased 2.72%, 3.40%, B group is greater than the decrease in the A group, AT-VO2max, AT-Time increased by 2.96% (P> 0.05), 3.92% (P <0.01), B group the level of increase is greater than A group.The special exercise capacity changes:Dynamometer 2km: the altitude training, performance 2km ergometer increased by 1.88%. Instantly raised blood Bla 5.89%. A group score increased 2.78% (P <0.01). B group increased 0.98% (P> 0.05). Immediately after exercise Bla: A group increased 0.59%, B group increased 11.17%.Dynamometer 6km: altitude training and altitude training than before, scores increased 1.86% (P <0.01), instantly Bla increased 21.34% (p <0.05). A group of Bla immediately increased 31.92% (P <0.05). B group increased 7.93% (P> 0.05), two scores were increased 1.89% (P <0.05).6 Test: The test found that after the plateau, the level of anaerobic threshold intensity under the increased lactate - exercise intensity curve significantly shifted to the right; aerobic exercise capacity increased, B group was greater than the A group.Conclusions:(1), after altitude training in 8 weeks, Hb, RBC and other indicators have a high level, to keep longer; shows the body's ability to carry oxygen enhancement. Athletes and other indicators declined slightly VO2max, anaerobic threshold indicators have improved, exercise time to extend that athletes, the higher intensity exercise oxygen uptake and utilization of the capacity increase, while the maximum exercise intensity in aerobic capacity of the body under no increase. Meanwhile, the Players aerobic capacity and aerobic capacity generally have been well improved.(2), 8 weeks of initial altitude training on altitude training group and a series of altitude training group improved aerobic capacity, the initial low altitude training group exercise intensity to improve aerobic capacity under the obvious, but many altitude training Higher intensity exercise group, under aerobic capacity were significantly increased, this may be due to: high altitude training group after several athletes, on the plateau environment is more adaptive when the environment changes, the body can be its own metabolism, functional and structural changes to to make suitable adjustments.
