ABSTRACT
OBJECTIVE:
The purposes of this study were to investigate the effect of suspension, the electrical stimulation and full weight bearing treadmill training on the muscle atrophy and transformation of muscle fibers.METHOD:
Forty Spraque-Dawley rats were divided into control and 3 intervention groups suspension control (n= 10), suspension with weight bearing treadmill (n=10), and suspension with electrical stimulation (n=10). After 4 weeks intervention, both gastrocnemius and soleus were dissected and the muscle weight and transformation of muscle fibers were analyzed.RESULTS:
In suspension control and suspension electrical stimulation groups, muscle to body weight ratio of gastro-cnemius was decreased compared to control group (p<0.05). In all intervention groups, muscle to body weight ratio of soleus was decreased compared to control group (p<0.05). In suspension electrical stimulation group, type I muscle fiber ratio of gastrocnemius was increased compared to control and suspension control groups (p<0.05). In suspension electrical stimulation group, type IIa muscle fiber ratio of gastrocnemius was increased compared to suspension control group (p<0.05).CONCLUSION:
It is suggested that muscle atrophy induced by disuse and transformation of muscle fiber can be prevented by electrical stimulation intervention.
