Which of the following is an example of a one-way repeated-measures research design?
A) Twenty rugby league players volunteered for a resistance training study. A one-repetition bench press was measured before the training began, at week 3 and then again in week 6 to evaluate strength gains.
B) Twenty rugby league players volunteered for a strength training study. Ten players were randomly allocated to a resistance training programme and ten randomly allocated to a plyometric training group. A one-repetition bench press was measured before the training began, at week 3 and then again in week 6 to evaluate strength gains from each method of training.
C) Twenty rugby league players volunteered for a strength training study. Ten players were randomly allocated to a resistance training programme and ten randomly allocated to a plyometric training group. A one-repetition bench press was measured at the end of the 6 weeks to evaluate strength gains from each method of training.
D) None of the descriptions are appropriate for a one-way repeated-measures research design.

In this example, the same variable (one-repetition bench press) is measured at three different time points, making it a one-way repeated-measures design. The participants are the same throughout the study.

Answer: B and C are not appropriate for a one-way repeated-measures design. In B, participants are divided into two groups, making it a between-subjects design. In C, the measure is taken only once, at the end of the study, and does not involve repeated measures.

Therefore, the correct answer is A.
