At first glimpse, swinging a golf club looks really easy. However, it requires a high level of precision, physical control and coordination and is among the most technically challenging motion sequences in sport. The ball lies just above the ground and has to be hit accurately with a club head measuring just ten by five centimetres. On impact, the golfer must hit the face of the club at a precise right angle and while doing so, take the ground conditions, distances, wind strength and gradients into account.
Reasons for Custom-Made Golf Clubs
Selecting the right club is crucial to the perfect golf swing. The club must be tailored to the individual measurements of the player as well as his or her unique requirements. If, for example, the club is too long, it becomes difficult to control. On the other hand, if it is too short, the player has to stoop, and achieving the correct shoulder turn from such a stance is challenging.
In golf businesses or specialist departments, clubs tend to come in standard versions. These naturally suit players who match such standard measurements. However, the majority of players don't fit the norm and require clubs that are custom-made.
This is where Mr. Erhardt brings his fitting service into play. The first step is to measure his customers. The ideal club length can be determined by using body height, distance from hand to floor and other factors. Then an analysis is performed of body movements. To do so, Mr. Erhardt uses the MotionBLITZ EoSens® mini1 high-speed camera.
On average, a golf stroke is executed in just 0.8 - 1.5 seconds. The club head can reach a speed of up to 200 km/h when wielded by an experienced player. But such details of a swing can't be picked up with the naked eye. The MotionBLITZ EoSens® mini1 provides detailed slow-motion recordings, which Dietmar Erhardt analyses.
The recordings provide important findings relating to the best material to choose for the shaft. For example, the greater the club head speed in relation to timing, the more the shaft is inclined to bend out of shape. For players with a fast, powerful swing, a less flexible shaft is therefore recommended. This allows the player to have increased control over the stroke. For older players or beginners with a slower, weaker swing, a shaft made from a more supple material is advised. With a shaft made from graphite, the weight shifts to the club head and the total weight is reduced, enabling improved acceleration.
