Abstract: This paper explores the technological applications and future development of virtual simulation technology in sports anatomy research. It begins by providing a comprehensive overview of how virtual simulation has been utilized in studying bones, muscles, and joints. This includes skeletal modeling and biomechanical analysis, muscle mechanics research, kinematic analysis of joints, and posture and movement optimization. The paper then delves into the various technological applications of virtual simulation in sports anatomy research. It discusses modeling and simulation techniques, motion capture and pose estimation, force feedback and physical simulation, as well as soft tissue modeling and simulation. Furthermore, the paper presents an outlook on the future development directions and research prospects of virtual simulation in sports anatomy. It highlights the integration of virtual reality and augmented reality as well as the application of artificial intelligence technology. The paper also mentions the importance of interdisciplinary integration and collaboration. In conclusion, this paper summarizes the innovations and contributions it has made in exploring virtual simulation technology in sports anatomy research. It emphasizes the significance of virtual simulation in this field and its potential for further development. Researchers in sports anatomy will find this paper valuable as it provides references for their work and contributes to the overall development and innovation of the domain.

Abstract: The aim of the research is to a comparison between two methods of power training, strength-speed and speed-strength on the performance of 50-meter freestyle swimming. The experimental method was applied to a sample of 12 adult swimmers (mean +/-SD: 16 +/-1 year, 172.2+/-3.2cm, 78.2+/-2.3kg) divided into two experimental groups, group A (strength-speed) and group B (speed-strength) by applying pre-and post-measurements,1RM bench press, 1RM squat, medicine ball chest throw, vertical jump, stroke length (SL), stroke rate (SR) and 50-meter freestyle tests was applied on the subjects respectively, Statistical Analyses Repeated-measures analysis of variance (ANOVA) was used to compare 50-meter freestyle trial time performance after the 2 different power training methods. Statistical significance was accepted at (p <0.05), (p <0.01). A 6-week power training program was applied 3 times a week, results show significant differences between pre and post-measurements in stroke length (t=3.64) and stroke rate (t=7.00) in group A, 1RM squat (t=3.60), vertical jump (t=4.96), stroke length (t=6.76) and 50-meter freestyle (t=32.91) in group B, and non-significant differences in 1RM bench press (t=2.33), 1RM squat (t=2.22), chest MD ball throw (t=2.35), vertical jump (t=2.18), and 50-meter freestyle (t=1.93) in group (A),1RM bench press (t=2.61), chest MD ball throw (t=2.08) and stroke rate (t=1.40) in group (B) for post-measurements. Present results recommend that dry-land program training must include the two methods of power training, strength-speed, and speed-strength, based on the force-velocity relationship for sprint swimmers during a specific period, power training in these two methods improves stroke length, and stroke rate and it leads to enhance swimming performance in sprint events.
