The main objective of this research was to develop a method which could be used to get the ultimate golf-swing and improve the ability of performing them. This will be shall by using a comparative analysis of the male progolfers` swing movements and the angles taken with each shot, especially at 0, 10, and -10 degree slopes. As a result of using advanced image analysis equipment to analyze each golf swing at the slope, we conclude as following. First, it appears that there is no difference in the entire swing time and the time it takes to perform each step of the proper hitting form. As a result, regardless of slope (whether it is 0, 10, or -10 degrees) the total swing time is all the same. Second, the experiment shows the following results. -The displacement of body`s center of gravity at each slope is not a variable. - The direction of the ball when hit will vary from each slope. - When hitting from a slope, the original center of gravity for a body after the ball was hit, moved about 8.45cm from the place where the shot was taken. That is a 62.36% change from the original center of gravity, which was found by calculating the total movement of gravity. -If you have a slope, the average body movement was restricted by 8%. -It shows that the movement in the upper and lower parts of your body will have a significant effect on the shot when hitting from a slope. Third, the experiment shows the following results. -When hitting from the slope, the angle of the right knee after the shot always differed from the original angle of the right knee, but when shooting from 10, 0, and -10 degree angles, the 10 had the most change, while the 0 and -10 degree shots followed, respectively. - The difference of the angle in the left knee from the original stance had the most change during the downswing to impact. Fourthly, the experiment shows the following results. -The speed of the club reached its peak just before impact regardless of the slope, which means the top speed of the club in the slope of 0 degree is faster than those of the 10 and -10 degree. 0 degrees resulted in 29.7 m/s 10 degrees resulted in 27.6 m/s -10 degrees resulted in 28.1 m/s Comparing the results of each slope to the shot taken from 0 degrees, the top speed of the club decreased by an average of 5% at the downhill slope whilst the uphill slope decreased by an average 7%. Finally, the experiment shows the following results. Shooting from a 0 degree angle resulted in a speed of 56.5m/s. Shooting from a 10 degree angle resulted in a speed of 54.3m/s. Shooting from a -10 degree angle resulted in a speed of 55.8m/s. Compared to the shot taken at the flat slope (0 degrees), the ball speed will decrease by 1.3% when shooting from a downward slope, and it will decrease by 4% when shooting from an upward slope. This means that shooting from a flat surface will give you the best results.
