Question 99

A sports scientist conducted a study to compare the effectiveness of two different 10-minute warm-up routines designed to improve the reaction times of competitive esports players.

  • Routine A: Dynamic hand-eye coordination drills using a digital target-board.
  • Routine B: Static upper-body physical stretching exercises.

A sample of players was randomly assigned to one of the two routines. Each player's reaction time (in milliseconds) was measured immediately before and immediately after completing their assigned warm-up routine.

Table 1: Mean reaction times and standard deviations for Routine A and Routine B

What do the mean values in Table 1 suggest about the effectiveness of the different warm-up routines? Justify your answer.
