Most players string too tight and then blame the strings

Tension is the one piece of equipment a player can change every day, which is exactly why it becomes a place to put anxiety.

A player loses in three sets, walks past the stringer and asks for two kilos tighter. This is a ritual. It is rarely a diagnosis.

The mechanics run in the opposite direction to intuition. A tighter string bed deforms less, so the ball spends less time in contact and the strings return less energy, which means less power and a smaller margin for error. A looser bed acts more like a trampoline, gives more depth for the same swing, and because the main strings can move and snap back it often produces more spin, not less. So the player who tightens after spraying balls long has usually made the ball go shorter by reducing power, which fixes the symptom and hides whatever was actually wrong.

What was actually wrong is usually the swing. Balls fly long when the racket face is opening under fatigue or when the player is arriving late and pushing instead of brushing. Neither of those is a tension problem, and correcting it with equipment means the fault is still there next week, now sitting on top of a setup that hits shorter.

There is a real cost too. Tight polyester at low temperature is brutal on the arm. The shock the string bed does not absorb goes somewhere, and that somewhere is the wrist and elbow. A great deal of amateur tennis elbow is a stringing choice.

My position, and stringers will nod while players ignore it: most club players should drop several kilos from where they are and switch to a softer string, and most professionals adjust tension far more often than the difference is detectable. Conditions matter, certainly. Heat makes a ball livelier so tightening in a hot week is defensible. Altitude is a genuine reason. Losing a match is not.

The strings also change on their own. Polyester loses tension quickly, most of it in the first hour of play, so a racket strung two days ago is not the racket that was requested. Professionals handle this by carrying many frames strung at staggered times and rotating them. Everyone else plays on a string bed that is slowly becoming something else and calls the racket inconsistent.

If you want to know whether tension is the problem, string two identical frames two kilos apart and hit both blind.

Almost nobody does this, because the answer might be that it never mattered.
