Purpose: Sports fatigue is a common among track and field athletes. Among them, the recovery of hamstring fatigue in the hamstring is particularly important for athletic performance and injury prevention. However, current rehabilitation methods often have limitations. This study aims to compare the effects of fascia knife therapy, traditional Chinese medicine, and their combined intervention on hamstring fatigue recovery, and to establish a multidimensional evaluation system through electromyographic signals. Methods: A total of 20 track and field athletes were recruited for this study using a randomized experimental design, a total of 17 eligible subjects (n=17) were ultimately enrolled for statistical analysis, all in the experimental group, further subdivided into fascia knife, traditional Chinese medicine, and combined intervention subgroups. The intervention lasted for six weeks, with electromyographic signal data collected immediately after training and 24 hours post-intervention. Results: The combined intervention of fascia knife and traditional Chinese medicine worked much better than the single interventions in recovering hamstring fatigue in track and field athletes. Two-way repeated measures ANOVA indicated significant interaction effects between time and group factors on RMS (p-value of 0.022, which is less than 0.05) and iEMG (p-value of 0.043, which is less than 0.05), with a significant main effect of the MF time factor (p-value of 0.019, which is less than 0.05); 24 hours post-intervention, the combined intervention group showed significant differences in RMS (p-value of 0.0014, which is less than 0.01) and iEMG (p-value of 0.0002, which is less than 0.01) compared to the fascia knife group, and the traditional Chinese medicine group showed significant differences in iEMG compared to the fascia knife group (p-value of 0.033, which is less than 0.05). The decline in MF in the combined intervention group was significantly greater than that in the traditional Chinese medicine group (p<0.05), indicating a synergistic effect of the combined intervention, which can effectively alleviate hamstring fatigue and enhance athletic ability. Conclusions: The combined intervention of fascia knife and traditional Chinese medicine shows significant advantages, followed by the intervention of fascia knife alone, and the effect of traditional Chinese medicine alone is relatively weak. It is recommended to prioritize the promotion of combined intervention in the track and field athlete group, which can shorten the recovery period and reduce the risk of sports injuries, ensuring the stable performance of athletes in their competitive form.
