The Outstanding Young People Swim The Athlete Individual Lactic Acid Threshold Analysis And The Application

This article increases progressively the load test by7×200m the pond in, observes the young people through the dynamic blood lactic acid change to swim the athlete individual lactic acid threshold, explores 13~16 year old young people to swim the athlete individual lactic acid threshold characteristic, provides the basis for the scientific training and the teaching, swims the athlete physiology function for the young people and the energy metabolism longitudinal research provides the parameter. Result demonstration that, 13~16 year old young people swim athlete's lactic acid threshold mean value for2.77±0. 70mmol/L, scope betweenl. 99~3. 99mmol/L, and the individual difference is more obvious, 13 ~ Hyear old of group for2. 69 ± 0. 77mmol/L; 15 ~ 16year old of group for 2.86 ± 0.65mmol/L, the young people athlete's individual lactic acid threshold compares the adult to be somewhat low, also is lower than 4mmol/L, but is higher than the baby and the children; 13~14groups of individual lactic acids threshold corresponds swims fast for1.28±0.05 m/s, 15 ~ 16year old of group for 1.32±0. 03m/s;25 are tried the object the blood lactic acid peak value mean value for7. 16 ± 2. 05mmol/L, the male team member blood lactic acid peak value mean value for7. 65 ± 2. 12mmol/L, the female team member's blood lactic acid peak value mean value for6. 25 ± 1. 80mmol/L, two groups of center male team members' biggest blood young acid values has extremely significant the difference, two groups are tried the object the blood lactic acid peak value to appear in the recovery period 3rd minute; increases progressively the load test to obtain the blood lactic acid to swim the fast curve, the heart rate swims the fast curve to demonstrate that, 15~16 year old of group' s blood lactic acid swims the fast curve, the heart rate swims the fast curve compared to 13~14 groups of overall right laterals, namely 15~16year old of group has the oxygen and the non- oxygen ability all good to 13~14groups; The curve change demonstration blood lactic acid and the heart rate certainly do not assume the synchronized change tendency, the blood lactic acid target can the more accurate local other swimming athlete organism withstanding different load change. Through to the individual lactic acid threshold analysis and the appraisal, is tried each the object the test result as well as between them the crosswise contrast analysis feedback gives the trainer, and has the oxygen at the winter training to train in the plan making, according to team member' s individual difference, reasonably arranges to have the oxygen to train the intensity and the science monitoring, has obtained the preliminary effect.
