The purpose of this study was to measure the muscle activity and muscle fatigue of the trunk and lower extremity muscles during running on the Non-motorized Treadmill, Motorized Treadmill and Overground. In 15 healthy male, we compared muscle activity and muscle fatigue during running exercise with a constant distance from a Non-motorized Treadmill, Motorized Treadmill and Overground with self selected constant velocity. We will identify the characteristics of each exercise condition and use it as the basic data for selecting the most suitable exercise condition for the purpose such as training, conditioning, rehabilitation in the future. This study suggests that the characteristics of each exercise condition are understood by comparing the muscle activity and muscle fatigue during Non-motorized Treadmill, Motorized Treadmill and Overground, In future studies, more data will be collected by using various age groups and various speeds. Based on this, we will be able to present effective exercise. The muscle activity and muscle fatigue of trunk and lower extremity muscles were different in exercise condition and exercise period. However, there was no significant difference in all exercise conditions and exercise periods. This suggests that various variables such as subject, exercise condition, and exercise intensity should be considered as a result of contradiction with previous studies.

The purpose of this study was to evaluate the effects of a high intensity ankle stability exercise of ankle isokinetic muscle function and posture balance in college students with chronic ankle sprain. The high intensity ankle stability exercise group participated in the exercise program for short-term (12 times) and the effects on isokinetic muscle function(peak torque, total work) and posture balance(weight distribution index, stability index) were evaluated. The high intensity ankle stability exercise group in analyses of ankle muscle functions, as for changes in Peak Torque, significant improvements were shown in right and left Plantar Flexion. With regard to changes in total work, although significant improvements were shown in all variables. Posture balance was improved but no significant difference was seen. To conclude, applying the high intensity ankle stability exercise of short-term period appeared to effectively improve the fundamental ankle muscle function and posture balance in college students of chronic ankle sprain. This research can provide a guideline of the effective verification model of a high intensity ankle stability exercise of short-term period exercise program to college students of chronic ankle sprain.

The purpose of this study is to analyze how 4-week hip adductor muscle exercise influences a degree of adductor muscle power and pain of female students with premenstrual syndrome. The study subjects were 8 female students in their 20s going to K-university in S city of Gyeongsangbuk-do, who had pain caused by premenstrual syndrome. VAS test as a study method was applied to look into a subjective pain degree. Isokinetic test was conducted to look into hip adductor muscle power. The results are summarized as follows : 1. According to the test on hip adductor muscle power, Peak torque weight 60°/sec was significantly different in the right sides(p<.05), and left sides(p<.01). Average power 60°/sec was statistically and significantly different in the right and left sides(p<.01). Total Work 60°/sec was statistically and significantly different in the right and left sides(p<.01). 2. According to VAS test, pain was significantly alleviated(p<.01). It is expected that more research on premenstrual syndrome will be conducted.

The study is for effect of sling exercise and proprioceptive neuromuscular facilitation on foot pressure and range of motion for strengthening quadriceps femoris and hamstring in accelerating training after total knee replacement. The study of subject is woman 40 enforcing total knee replacement on both of knees in July 2002, getting surgery again (total of two times) from infection on left knee joints in September 2003 and April 2004. The exercise was applied with level of not being hard on body and pain by total knee replacement exercise, sling exercise and PNF leg pattern exercise for 3 time a week. The study showed with significant differences to pressure rate of left and right side of subject before and after exercise on foot pressure. The measuring angle was increased in range of motion.
