After Incremental Exercise Different Restoration Of Blood Lactic Acid, Muscle Oxygen Change Characteristics

Objective:This study aimed to the restoration of blood lactate and muscle oxygen content changes were observed and analyzed, compare what way is more advantageous to the athletes fatigue elimination and physical recovery, for the coaches how to arrange the fatigue of the athletes after training to eliminate way to provide the theory basis, to improve performance athletes to make the contribution.Research:This study athletes incremental exercise to exhaustion, and recovery after exercise in different ways, to eliminate changes in the rate, heart rate and muscle oxygen content of blood lactic acid after exercise to determine which approach is more conducive to athletes the fatigue recovery enthusiasm recovery which muscle oxygen content and blood lactate recovery correlation exploratory study to explore muscle oxygen parameters in human movement recovery and their metabolism may assess application feasibility, sports training guardianship in order to provide new indicators and scientific testing methods.Methods:12volunteers for the Wuhan Institute of Physical Education Sanda athletes, athletes in a test prior to the first preparatory activities for lmin without resistance after the test starting load for50W per minute increments of15W, continuous exercise to exhaustion. A group of athletes in a positive way to recovery after exhaustive maximum power of40%to continue the movement20min, immediately after exhaustive exercise,1,3,5,7,10,15,20min, were collected from the peripheral blood, collected blood for20μL. Blood samples after collection were immediately detected. Group B athletes after exhaustive exercise to maintain vertical position ride, take stationary rest negative way to restore immediately after exhaustive exercise,1,3,5,7,10,15,20min, were collected from the peripheral blood, collected blood20uL of. Blood samples after collection were immediately detected.△HbO2content relative change in the three-wavelength near-infrared portable muscle oxygen detector monitoring subjects quadriceps exercise and after exercise.Results:After30min, recovery after exercise, positive recovery in group A the average level of the athletes’blood lactate3.62±1.14mmol/1, the use of the passive recovery group B athletes, the average blood lactate level of4.42±1.76mmol/1passive recovery on blc lactate clearance rate has lagged far behind in the enthusiasm of recovery. A group of mus oxygen active recovery recovery after exhaustive exercise half the average recovery rate recovery of125.26±1.58, negative-type recovery group B half of the muscle oxygen recovery rate of111.91±2.13, passive recovery on muscle oxygen The rate has lagged far behind to recover the enthusiasm.Conclusion:This study investigated the increment load after exhaustive exercise, different recovery on blood lactate and muscle oxygen recovery rate, the results found using the active recovery mode group blood lactate and muscle oxygen recovery rate faster recovery in the negative The way groups, indicating that active restoration as fatigue after exhaustive exercise to eliminate one of the means is effective to provide a theoretical basis for the guidance of the scientific trainingofthecoaches Fatigue.
