The purpose of this study is to reveal the effect of KT and CS on DOMS. The main hypothesis was that KT combined with CS can alleviate DOMS by reducing inflammation, muscle damage, and fatigue. Through our research, this hypothesis was partially supported. Our main findings were shown as follows: (1) Compared with the control group, after using KT and CS, the pain score, fatigue index and occurrence degree of DOMS of lower limb muscles were significantly reduced after exercise immediately; (2) Compared with baseline, IL-6 and PT/BW value recovered faster after KT and CS were used together.Pain is a multi-dimensional experience and a prominent feature of many musculoskeletal diseases. Accurate and reliable measurement is the premise of effective treatment. Although pain is subjective, it is a highly relevant complaint. Visual Analog Scale (VAS) is a quantitative assessment tool for pain, which can guide the determination of the impact of pain on the body [Zeynep et al. concluded that KT intervention can reduce the muscle soreness of the quadriceps femoris in fifty-four nonathletic volunteers [The development of muscle damage caused by DOMS is a process of increasing pain and body load. Therefore, participants should pay attention to the recovery process of physical fatigue and DOMS. After the occurrence of DOMS, the subjects were asked to rest for a while and reduce the amount of exercise when the pain reaches the maximum value to avoid the aggravation of pain and the development of tissue injury into muscle damage. It can be seen from the increase of VAS in different intervention groups 24 h after exercise. After using CS, KT, or CS combined with KT, the occurrence degree of DOMS and pain showed a decreasing trend, indicating that these additional measures played a protective role in DOMS and prevented the occurrence and development of DOMS.IL-6 is a cytokine related to exercise. It is involved in a complex series of biological reactions in the body, often playing a role in inflammation, immune response, and bone metabolism. At the same time, it is also a strong inflammatory response factor that causes pain and can be used as one of the important outcomes of the inflammatory response [Skeletal muscle damage is the main cause of IL-6 release caused by exercise. It is also related to exercise stress, exercise intensity, heart rate during exercise, adrenaline, and so on [A large number of studies have shown that peak torque is the expression of the maximum torque in the process of joint flexion and extension, the embodiment of muscle strength, and has good repeatability. It is regarded as the gold standard and reference value of the isokinetic test, while relative peak torque (PT/BW) is the percentage of peak torque in body weight, excluding the influencing factors of body weight, which can be used to compare the torque between different individuals. The intergroup analysis found that compared with the CG, the improvement of PT/BW by using CS, KT, or CS combined with KT at 24 h after the intervention was statistically significant. It shows that after the production of DOMS, CS and KT can inhibit DOMS, to improve PT/BW. The intragroup analysis found that the PT/BW of CG decreased first and then increased after modeling. At 72 h, the upward trend still did not return to the mean value before modeling. The reason for the above results may be that once DOMS is produced, it will spread to the whole muscle participating in the exercise. The degree of muscle tissue damage is directly proportional to the recovery time and inversely proportional to the exercise ability. The more serious the injury is and the longer the recovery time is, the weaker the exercise ability is, resulting in such a changing trend of PT/BW [WF is the main index to reflect the strength and endurance of lower limb joint muscles. There is no single cause of muscle fatigue. The main mechanism is specific to those processes under pressure during fatigue exercise. This concept is similar to the principle of specificity [According to research and analysis, when CS is used, perceived fatigue is significantly reduced. Research shows that wearing CS within 24 h after high-intensity resistance training can significantly reduce perceived fatigue [
