Effects of a stress-management program on injury and stress of competitive gymnasts.

20 competitive gymnasts (17 girls, 3 boys; mean age, 14.4 +/- 3.4 yr.) were recruited from two clubs in Auckland, New Zealand. Gymnasts, who had competed at a national or international level, were divided into two groups to examine the effects of a longitudinal stress-management program on injury and stress. Those in the stress-management group took part in 12 1-hr. sessions over 24 weeks, while the control group took part in a placebo program of anthropometric measurements and lectures on nutrition. All participants completed the Life Experiences Survey and Athletic Experiences Survey at baseline, 3 mo., 6 mo. (end of intervention), and 9 mo. (3 mo. after completion of intervention). Injury data were collected prospectively by weekly self-report over the 9-mo. study. Repeated-measures analyses of covariance with age and, where applicable, the baseline measure of the dependent variable entered as covariates, indicated no significant group or group by time effects for the scores on the two surveys, or injury scores. However, given the small sample, the statistical power of the study to detect even large effects was low. Therefore, rather than concluding that the stress-management program had no effect on training hours lost to injury or on stress, upper limits were placed on the magnitude of any effects that might exist. Further research using larger samples is recommended.
