| Summary: | 碩士 === 臺北巿立體育學院 === 運動技術研究所 === 99 === Purpose: The purpose of the study was to explore differences of balance and neck fitness between weight lifting athletes and non-athletic university students. Changes on balance functions and neck fitness were observed after ice compress on articulatio sternoclavicularis of sternocleidomastoid. Methods: Sensory Organization Test was administered with Computerized Dynamic Posturography using Smart Balance Master, and microFET3 was used to test isometric strength and active joint range of motion on six different directions of the neck. Posttest was conducted after ice compress using an ice bag. Results: 1. Significant differences of main effect were found on all conditions and total scores of sensory organization between pre and post tests regarding time. All subjects were found to have a significant interaction in condition 5, and balance scores and total scores were increased after ice compress. Ice compress was more effective on university students in condition 5. 2. All subjects had higher maximal isometric strength after ice compress in all directions. Weight lifting athletes had higher isometric strength than university students before ice compress, and ice compress was more effective on flex and rotation on weight lifting athletes. 3. All subjects had better active joint range of motion after ice compress in all directions. Except flex, weight lifting athletes had better range of motion than university students before ice compress, and flex active joint range of motion was not enhanced after ice compress. Conclusion: Neck muscle strength, balance, and neck range of motion of weight lifting athletes were enhanced after ice compress, especially in neck muscle strength and balance. Therefore, ice compress is helpful for neck injury prevention, and further enhance weight lifting performance. Ice compress as a neck protection is suggested after training routines for weight lifting athletes for the effects of protection and performance enhancement.
