Expansion System in Golf
Since technical performance in golf is of crucial importance, amateur golfers usually see golf more as a technical skill, often neglecting the physically demanding side of the sport. The required level of psychophysical fitness is frequently underestimated, leads to the misbelief that the improvement of a golfer’s performance depends solely on a diligent technical training of their swing. Golf is a technically very demanding sport and requires a good physical condition of the players. While performing a golf swing, an amateur golfer typically reaches 90% of their maximum muscular activity. In other words: if we compared the intensity of a golf swing to the intensity of weight lifting, a swing would equal the weight we can lift four times; a technically correct execution of the fifth lift would be impossible due to complete muscular fatigue. In an average play the golfer produces 30 do 40 swings of approximately the same intensity. Golf is thus a highly explosive sport, which also demands a good muscular endurance, since an average amateur play lasts from 3 to 4 hours. American researchers have found that the level of strain and muscular activity in golf is comparable to those in football, hockey or martial arts.
