Shaft flex and swing...

[Tiger]

Just been wondering something about flex quite possibly a question for the likes of swinger and his scaffold poles. Is stiffness of shaft flex actually determined by the amount of lag you create? Been watching golf this weekend and so many swings are so rhythmic and smooth but the ball goes miles.

I've pole vaulted in the past so understand that the stiffer the flex the more power you can generate but just wondering where the power comes from to create the bend in the xstiff shafts they use?

Swing speed and how you load the shaft. Most could use a softer flex but you want to be able to feel where the head is, I find with a weaker shaft I have no idea where the club is.

But what is loading the shaft? cheers

somewhere (in time) from transition of the downswing to the left arm being just around horizontal to the ground (RH player) the shaft is bent backwards as a result of the inertia + mass of the club head and the torque exerted by the golfer through their dynamic motion.

depends where in 'time' plus how much energy is exerted through the players motion on the shaft in that short length from atop to halfway down, the above happens as to how much the shaft is 'loaded'.

{swing starts down from the ground up, motion passing energy/force (quickly) through the downswing feet, leg, hips, core, chest, shoulders, arm, hand, shaft as it gets to the ball releases the 'loaded' energy, clubhead being the last thing (should be) to reach the balls location}

Thank you :thup:
