Bei den Muskelfasern unterscheidet man
FT (fast-twitch), das sind die schnellen Fasern und
ST (slow-twitch), die langsamen.
Durchschnittlich besteht die menschliche Skelettmuskulatur ungefähr zur Hälfte aus schnellen und langsamen Muskelfasern. Einige Menschen haben einen besonders hohen Anteil einer Art der Muskelfasern. Menschen mit einem genetisch bestimmten besonders hohen Anteil an langsamen Muskelfasern haben im Leistungssport Vorteile bei Ausdauerleistungen wie z.B. Langstreckenlauf, Schwimmen. Bei anteilig besonders vielen schnellen Muskeln haben sie dagegen Vorteile z.B. beim Sprint, Golf.
Leider ist es nicht möglich aus langsamen Muskelfasern durch Training schnelle zu machen, umgekehrt doch.
Was genetisch vorgegeben ist, muss man aktzeptieren. Da der Golfschwung im Drive zur vollen Leistung schnelle Muskelfasern erfordert, ist derjenige mit ST Fasern benachteiligt!
Sorry.

Need more power?
Get width in your swing.
Because women lack the physical strength men, achieving good distance is often a problem. But you can make up for this if you work on maximising the width of your swing, which in turn helps you to increase your speed and momentum through the ball. When you make your backswing, think about pushing your hands away from your body so that you achieve a high position at the top. Imagine you were standing in a doorway; push your hands into the top corner. Your left arm should be comfortably straight – but not rigid -and your weight should be behind the ball.
First of all a perfect control of your backswing.

From here, maintaining that width on the way back down will then enable you to accelerate the clubhead through the ball with considerable force. You want a sensation of free-wheeling through impact and using that momentum to unwind all the way through to a full and balanced finish, with your hands behind your head, arms relaxed.

Driver: glide the clubhead away from the ball, make a full wind-up
Once you are properly set up to hit a drive, you need to think about getting your weight behind the ball with a good wind-up. The first move is important in this respect. Try to feel that your left arm pushes the club away so that you create good width in your swing. Keep the clubhead low to the ground as you glide it back from the ball.
Doing this sets you on the way to a full backswing movement, turning your shoulders through a full 90 degrees. (am supple enough to do this without lifting my left heel off the ground, but don’t worry if you need to let yours come up a little to make a full turn.) Once you have coiled your backswing, give yourself time to unwind.
Don’t hit at the ball from the top. Wait a moment; let your weight settle back towards the target (i.e. feel it flow back to the left side) and sense that your arms and hands drop the club on to a shallow inside path. Once you are in this hitting position, you can enjoy sweeping the ball off the tee, releasing the clubhead past your chin as you unwind.
