Qi, Y, Shi, D & Zhou, S 2010, 'Study on cross education of six-week unilateral isotonic resistance training for wrist flexion and extension', Chinese Journal of Rehabilitation Medicine, vol. 25, no. 5, pp. 425-429.
Objective: To investigate the effects of six-week unilateral isotonic resistance training for wrist flexion and extension on the strength increment and cross-education to provide experimental evidence for clinical rehabilitation.
Method: Twenty-two college students (male, mean age at 21) volunteered to take part in the research, and were randomly divided into training group and control group. Evaluations of isotonic muscle strength of both side wrist flexion and extension in all subjects were performed pre- and post-experiment. Then, six-week right wrist flexion and extension resistance training in training group was proceeded. The subjects in control group kept daily activities without training during the experiment period. Result: In training group, the muscle strength of right wrist flexion, left wrist flexion and left wrist extension increased by 19%, 12% and 41%, respectively. Significant differences were found for all of them compared with those of control group(P<0.05, P<0.05, P<0.01). Even though the strength of right wrist extension in experiment group increased by 32%, no difference was found compared with that in control group(P=0.059).
Conclusion: Good cross education was proved under the condition in this research，which might offer a new way for clinical rehabilitation practice in requiring cases.
