Variable effects of a behavioral treatment package on the performance of inline roller speed skaters.

We investigated the effects of a treatment package on the performance of correct relay tags with 4 inline speed skaters. The treatment package included verbal praise following correct tags, visual feedback of performance data, and instruction for improving performance. Initial gains in the frequency of correct tags were not maintained at 6-month follow-up when baselines were reestablished. Performance on the second intervention phase for the 3 original subjects was variable and differed from the initial phase, whereas the original findings were replicated in the 4th subject. Possible reasons for this variability and implications for future research and behavioral sport interventions are considered.
