Introduction: Chinese boxing demands the maximum potential from its practitioners. The quality of executions of single or multiple punches depends on adequate strength training, and the quality of speed is a crucial factor for victory in Chinese boxing competitions. Objective: Explore the effects of strength training on the speed of punches in Chinese boxing athletes. Methods: Eighteen Chinese boxers were selected by random sampling. The competitors perform functional exercises directed at strength training for ten weeks. Several key points of sports aerobics were comprehensively evaluated. Mathematical and statistical methods were applied in processing the data before and after the intervention. Results: The speed quality of Chinese boxing practitioners after strength training was statistically beneficial (P<0.05). Only the particular qualities of strength did not show significant differences among the four unique qualities of strength analyzed; there were significant differences among the other three abilities (P<0.05). Conclusion: The introduction of functional strength training into the physical training of high-level Chinese boxing athletes can significantly improve the quality of movement speed. Functional strength exercises are a safe and efficient form of exercise. This training protocol provides a good reference to compensate for the shortfall in conventional strength exercises.

Introduction: Recent studies have shown that altitude training can significantly improve hemoglobin content in athletes. This allows for greater oxygen transport to the muscles and, consequently, greater load capacity during training. However, there is no confirmed evidence of athlete-specific training in martial arts. Objective: Explore the load capacity and ability changes caused by high altitude training in athletes. Methods: The research selected ten high-level martial arts athletes as volunteers to compare the functional changes caused by high-altitude training. Physical and functional data were collected before the beginning of the experiment and at its conclusion after three weeks. Results: Measured abilities were significantly improved after 11 days of altitude physical training. After 21 days of altitude training, these abilities improved significantly. The urea nitrogen and creatine kinase values increased rapidly with increasing load intensity in the first stage, peaked in the second stage, and decreased in the third stage. Conclusion: Training in the low-pressure hypoxic environment at high altitude, using dual stimulation of hypoxia and exercise to make the athletes stress response, can stimulate the physical potential to achieve a range of physiological abilities to improve the body’s resistance to hypoxia.
