The ski diagonal stride technique is a crucial component in cross-country skiing, engaging complex muscle coordination, enhancing cardiopulmonary function, and improving balance. In the realm of rehabilitation, traditional methods often face limitations. This study is dedicated to exploring how the physiological factors associated with this technique affect the rehabilitation treatment outcomes. By doing so, it aims to optimize rehabilitation strategies and ultimately enhance patients' physical capabilities and quality of life. Method: Eighty patients between the ages of 30 and 60, all in need of lower-limb rehabilitation, were evenly distributed into an experimental group and a control group. The experiment was carried out in a specialized rehabilitation institution. Over 16 weeks, the experimental group underwent training centered around the ski diagonal stride technique. Starting with simple movements, the training gradually advanced to simulate more challenging diagonal stride situations. They trained 5 times a week, with each session lasting 45 minutes. Meanwhile, the control group adhered to traditional lower-limb rehabilitation training. To accurately assess the effects, surface electromyography instruments, cardiopulmonary function monitors, and balance testing devices were employed. Data were collected at the beginning of the training, after 8 weeks, and at the end of the 16 - week then analyzed using SPSS software. After 16 weeks of training, the experimental group exhibited significant improvements. The maximum isometric contraction force of key muscles, such as the quadriceps femoris, increased by 40%, compared to a 20% increase in the control group. Muscle fatigue was delayed by approximately 30% in the experimental group, while the control group showed only a minor improvement. The experimental group also experienced a 15% increase in maximum oxygen uptake, with more notable improvements in ventilation efficiency compared to the control group. Additionally, the single-leg standing time and the scores of the closed-eye balance test in the experimental group increased by 35% and 40% respectively, contrasted with 15% and 20% in the control group. All these differences between the two groups were highly significant (p < 0.01). The findings indicate that the ski diagonal stride technique is more effective in rehabilitation treatment than traditional methods. However, this study has its limitations, including a relatively small sample size and a short observation period. Future research could address these issues by increasing the sample size and prolonging the observation time. This research provides rehabilitation professionals with new perspectives for treatment optimization.
