The purpose of this study was to examine the effects of isokinetic muscle training and binaural beat training of college golf players on their performance. The subjects are composed of 20 superior and inferior college golf players with normal skeletomuscular and psychological functions. Isokinetic muscle training was done on the wrist, shoulder and other major joints at angular velocities of 60, 180 and 240 using the IsoMed 2000 equipment, and a gradual muscle relaxing exercise. According to this study, driving accuracy after training was significantly higher (p<0.01) in both groups compared to that before training. Greens in regulation was higher in both groups after training compared to that before training. The standard of putting was also higher in both groups after training compared to that before training (p<0.01). The par save rate was higher in the superior group than that of the inferior group. Repeated measurements made for each group`s game score before and after training showed to have an interacting effect. Driving distance was higher after training compared to that before training in both groups (p<0.01). In conclusion, it is assumed that Isokinetic muscle training and binaural beat training can enhance detailed technical factors. Moreover, if carried out for a significant period of time, they will have positive effects on all groups, independent of their skill level, and reduce anxiety caused by competitive situations and improve muscle functions.

The purpose of this study was to analyze instructional contents Pilates instructors, characteristics of instructional content composition, and provide basic data for efficient Pilates instruction.<br/> The results from the analysis of instructional contents can be summarized as follows: First, instruction consisted of warm-up, main exercise, modification, and cool-down, which varied by instructors: some instructors implemented it in the order of warm-up → main exercise → warm-up and other instructors conducted it in that, without cool-down. Second, for warm-up instruction, Pilates instructors added stretching or yoga that they developed for themselves to relieve muscular tension and then entered warm-up instruction in some cases. Third, as for 10-session instruction, the same program was used for warm-up and cool-down while main exercise and modifications varied by sessions. Fourth, since the instruction was at the early stage for beginners with repetitive contents and thus could make members bored, such instruments as gymball, circle, band, and dumbbells were used to arouse their interest. Fifth, many kinds of music were used in Pilates instruction. Several instructors provided characteristic Pilates instruction with different atmospheres of music. In conclusion, in order to implement Pilates instruction efficiently, it is necessary for an instructor to use the time for supervising, lecturing and structuralization of instructional management efficiently through sufficient instructional plans before instruction in consideration of properties of Pilates to allow learners to spend much time in task-based physical activities and to implement learning tasks clearly and accurately by providing the teaching clue of correctional technique feedback.
