Comparing the effect of two different exercise types, minitrampoline and fast-walking to gastrocnemius/soleus muscle elasticity by sonoelastrography

Özet

Objectives: Sonoelastography is a newly introduced ultrasound technique that evaluates tissue elasticity andthus provides additional information to that offered by conventional ultrasound images. Here, we comparedthe effect of ballistic jumping on mini-trampolin with walk exercise to the elasticity of gastrocnemius/soleusmuscles with quantitative measurements by sonoelastography.Methods: Forty volunteer healty male cases between the ages of 20-22 years were included the study. Initially,both exercise groups were subjected to joint warm-up movements for 8 minutes. Twenty of the cases (40 legs)had mini-trampoline (balistic jumping) exercise for 15 minutes. Another 20 cases (40 legs) had 15 minutesfast-walk exercise. Measurements were made immediately before and after the procedure (within 5 minutes)with the sonoelastography.Results: A statistically significant difference was observed in the gastrocnemius/soleus muscles after exercisein the trampoline group according to sonoelastography strain value (SESV) data separately (p = 0.0001 / p =0.0001). According to this, when the SESV values evaluated after 15 minutes of jump with the trampoline, weobtained that the elasticity increases and stifness decreases in the calf muscles. In the walking group, nostatistically difference was observed in the gastrocnemius/soleus muscles after exercise separately (p = 0.7925/ p = 0.1879).Conclusions: According to the study, in the trampoline group in general, a decrease in strain values and anincrease in elasticityin muscle groups were found; in the walking group, a decrease in muscle elasticity, anincrease in stiffness and muscle strain were found eventually. We found that the 15-minutes exercise programon the mini-trampoline is more effective as a heating technique and has more positive effect on muscle elasticitythan the 15-minutes walking exercise.
