Sanda is a modern competitive sport in which two people use offensive and defensive techniques such as punches and legs in martial arts to overcome the opponent's unarmed confrontation according to certain rules. Sexual fighting items. In the game, Sanda players should adjust the game tactics at any time according to the situation of the opponent on the field, pay attention to the defense in the attack, and be able to seize the opportunity to give the opponent a fatal blow while defending. Therefore, in addition to having a good level of technical and tactical skills, Sanda athletes must also have sufficient physical reserves to ensure the normal performance of technical and tactical skills. Sanda competition has high requirements on the physical quality of Sanda athletes, so the body's three energy supply systems, ATP-CP system, glycolysis system and aerobic metabolism, play a vital role in the competition, among which the most direct and most important the energy supply for anaerobic glycolysis requires Sanda athletes to have higher lactate tolerance and lactate scavenging ability. With the development of the times, Sanda sports training has gradually moved from a single training study to a multidisciplinary scientific training. This paper takes 6 Sanda athletes as the research objects to track and test their physiological and biochemical indicators during the actual combat training in the plateau environment. The training provides an effective theoretical basis. During the plateau training, the hemoglobin and red blood cell index of the male Sanda athletes were well improved, which increased by about 10% compared with those before the plateau training, indicating that the aerobic capacity of the Sanda athletes was well improved.
