Book excerpt: Abstract: Gymnasts are frequently referred to physical therapy due to a high incidence of injury within the sport. Once an injury has been treated, physical therapists are faced with a lack of research enabling them to determine appropriate timeliness in returning the athlete to participation. Many therapists believe this determination, as well as injury prediction, may be made based on the evaluation of strength. Purpose: The purpose of this study was to examine the relationships between isokinetic strength scores, functional test measures, and incidence of injury in collegiate-level gymnasts. Subjects: Two Springfield College female gymnasts participated in this study. Both participants were 18 years of age, and had been competing in gymnastics for a total of 8 years. Methods: All subjects were tested in October of 2000 and January of 2001. During each testing session, each subject was instructed to complete a demographic questionnaire prior to testing. Lumbar range of motion was then assessed using the BROM IIR. Isokinetic strength testing utilizing the CybexRNorm dynamometer was performed next. Testing protocol consisted of the performance of concentric/eccentric quadriceps contractions at three angular velocities (60/second, 180/second and 300/second). Following the isokinetic strength testing, each subject performed the modified vertical power jump test, co-contraction test, and single leg 6-m hop for time test. Isokinetic testing was not conducted during the final testing session in January 2001 due to mechanical failure of the CybexRNorm unit in October 2000. Analysis: Inadequate sample size left the researchers unable to statistically analyze the gathered data as intended. Descriptive statistics were evaluated to examine measurement trends within and across each testing session. Results: Subject one showed no improvement in performance from baseline testing (October 2000) to final testing (January 2001) except during the co-contraction test, and perception of readiness to compete. Intra-trial trends demonstrated that subject one achieved better performance in later trials (trials 2 and 3) than in earlier trials (trial 1), except in measurements obtained for lumbar extension range of motion and modified vertical jump trials recorded in January, 2001. Analysis of baseline testing information showed that subject two also performed more efficiently during later trials. Due to injury, final testing data could not be gathered for subject two. Conclusion: As a result of a non-correctable mechanical failure in the CybexRNorm Dynamometer and a limited sample size, the researchers were unable to accept or reject the null hypothesis. Further research is required to establish the relationships between isokinetic strength scores, functional test measures, and incidence of injury in collegiate-level gymnasts.
