Why do tennis players switch sides?
Show answer & explanation
Answer: Equalizes sun and wind conditions
Prevents muscle imbalance — Wrong. Switching sides doesn't address muscle balance—it equalizes environmental conditions (sun, wind) both players face.
Allows court inspection — Wrong. Side switches aren't for court inspection—they equalize environmental factors (sun position, wind direction) affecting play.
Equalizes sun and wind conditions ✓ — Correct! Environmental fairness! Tennis courts often have environmental asymmetries: (1) Sun position—glare affects serving/vision. (2) Wind direction—favors one side. (3) Court surface irregularities. Players switch sides after odd-numbered games (1st, 3rd, 5th, etc.). Ensures both players experience same conditions over match—fairness! 90-second breaks during switches. Pros carefully time switches with sun movement. Outdoor tennis especially affected. Equalizing principle basic to sport fairness!
