Reliability of the FITLIGHT® System and acute effects of cognitive training on dual-task performance in cutting assessments

The FITLIGHT® system is comprised of individual lights that were programmed for cognitive dual-task testing and training protocols. PURPOSE: To determine the test-retest reliability of the FITLIGHT® system and the acute effects of cognitive training on injury risk in cutting and pivoting sports. METHODS: Seven subjects (M/F: 2/5; Age: 20 ± 0.58 y; Height: 1.67 ± .05 m; Mass: 63.61 ± 11.45 kg), randomized into two groups and completed three visits. Visit one consisted of familiarization. Visits two and three consisted of two normal T-Tests, followed by five cognitive T-Tests. Subjects then watched a film or performed cognitive training for 30 minutes, depending on group randomization. Subjects who watched the film on visit two completed the training on visit three and vice versa. After the 30-minute period, subjects repeated the T-Tests. RESULTS: Average time to completion during pre-training was 15.24 ± 7.18 s, while average time post-training was 14.04 ± 5.47 s with a percent change of -7.87%. Average time pre-video was 16.74 ± 9.19 s, while average time post-video was 10.84 ± 3.69 s, with a percent change of -35.25%. Two subjects decreased and two subjects increased time pre- to post-training. Three subjects decreased and one subject increased time pre- to post-video. CONCLUSION: In this small cohort, training did not improve performance on the cognitive T-Test and the control video appeared to have a greater impact on completion time. These results may be due to fatigue and concentration which anecdotally were present following the training session.
