Which of the following sports does NOT primarily require reaction time?

Weightlifting does not primarily require reaction time because the sport is focused on strength and technique rather than on responding quickly to external stimuli. In weightlifting, athletes primarily concentrate on their own physical capabilities and the timing of their lifts, which allows them to prepare and act in a controlled manner.

In contrast, the other options involve scenarios where quick responses are crucial. For example, in a 100m sprint, athletes must react promptly to the starting signal. Meanwhile, a goalkeeper in football needs to react quickly to shots on goal, and a batsman in cricket has to respond swiftly to various deliveries from the bowler. Each of these sports engages reaction time as a critical component for performance, making weightlifting distinct in its focus.
