For items that need to be stretched after exercise. Does stretching relax muscles or lengthen achilles tendon? This question has been questioned by many people. Let's start with stretching. Stretching can improve blood circulation. When doing strength training, muscles will be congested, and full stretching can effectively circulate blood. Stretching can discharge lactic acid accumulation, and there will be some lactic acid accumulation in muscles after fitness, especially for people who do not exercise for a long time, and their muscle ability will decline. Muscle soreness can be relieved the next day after training. Stretching can improve muscle lines, and stretching after fitness can play a role in shaping and make your muscle lines more perfect. Stretching can improve muscle function, and stretching after fitness can increase the range of muscle activity and enhance the coordination and adaptability of the body. Stretching can avoid sports injuries, which is also an important reason for stretching.
As for whether stretching can lengthen the achilles tendon, in fact, some relative training can lengthen the achilles tendon. The length of achilles tendon, like the tendon length of each muscle group, is determined by development, and is also related to the gene and nutrient intake in the acquired development process. The acquired exercise after development can not change the length of Achilles tendon, but only the separation and toughness of Achilles tendon muscle. The acquired exercise after development can not change the length of Achilles tendon, but only change the separation and toughness of Achilles tendon muscle. The usual stretching is to lengthen the ligament. Stretching can relax muscle fascia, and many bodybuilders will relax muscle fascia in a special way, which can promote muscles to absorb nutrients better and increase muscle growth. You can develop good exercise habits at ordinary times and drive tendon activities through muscle contraction and relaxation.
